Xo'sh, nima yaxshiroq bo'lishi mumkin (bundan tashqari) biologik parchalanadigan yoki qutulish mumkin bo'lgan idishlar)? Xo'sh, kichkina Keurig qahva va choy kapsulalari har kuni tabletkalarni olib tashlash uchun vitaminlar bilan boyitilgan ozuqa moddalari bilan kelgan bo'lsa-chi?

Bu aynan nima VitaCup vitaminli qahva va choy po'stlog'ining birinchi turini amalga oshirdi. Dunyoda eng sog'lom qahva ishlab chiqarildi San -Diego kompaniya asoschisi Brandon Fishman, to'rtinchi avlod Roastmaster Jeff MakIntosh va vitaminlar bo'yicha bosh direktor Brianna Hanratti, ro'yxatdan o'tgan parhezshunos va ovqatlanish shifokori.

Milliy sog'liqni saqlash va ovqatlanish ekspertizasi so'rovi shuni ko'rsatdiki, aholining uchdan bir qismi vitamin etishmasligi xavfi ostida, kasalliklarni nazorat qilish va profilaktika markazi esa aholining atigi uchdan ikki qismi etarli darajada ovqatlanmoqda. D vitamini. Daily Meal Hanratty bilan VitaCup sog'lom qahva liniyasi haqida gaplashdi.

Kundalik ovqat: Nega oldin bu haqda hech kim o'ylamagan? Sizning ilhomingiz nima edi?
Brayan Xanratti:
VitaCup missiyasi aholining ko'p qismida vitamin etishmasligi haqidagi statistik ma'lumotlardan ilhomlangan. Vitamin iste'mol qilishni boshqarish bizning vazifalar ro'yxatining oxiriga to'g'ri keladi, bu esa ovqatlanish etishmasligiga olib keladi, bu esa charchash, vazn ortishi va hattoki diqqatni to'g'ri jamlay olmaslikka olib kelishi mumkin. Biz qahvani suvdan keyin dunyoda ikkinchi eng ko'p iste'mol qilinadigan ichimlik ekanligini yaxshi ko'ramiz, shuning uchun iloji boricha ko'proq odamlarga vitaminlar aralashmasining sog'liq uchun foydasini berish maqsadimizga erishish uchun ajoyib vosita.

Agar siz S vitamini ko'p iste'mol qilsangiz nima bo'ladi?

S vitamini odatda yuqori dozalarda ham xavfsiz qabul qilinadi. Biroq, odamlar ba'zida ovqat hazm qilish bezovtalanishi kabi engil yon ta'sirga duch kelishi mumkin. Kamdan kam hollarda jiddiyroq yon ta'siri paydo bo'lishi mumkin.

S vitamini - inson tanasi uchun zarur bo'lgan vitamin. Bu antioksidant bo'lib, u qon bosimini pasaytirish, yallig'lanish bilan kurashish va kollagen hosil qilish kabi bir qator muhim jarayonlarga yordam beradi.

Ushbu maqolada biz S vitamini qabul qilishning tavsiya etilgan yuqori chegaralarini, haddan tashqari dozani qabul qilishning mumkin bo'lgan yon ta'sirini va boshqa ogohlantirishlarni ko'rib chiqamiz.

Pinterest -da bo'lishish odatda S vitamini yuqori bo'lgan taomlarni tez -tez iste'mol qilish xavfsizdir.

S vitamini yuqori bo'lgan ovqatlarni tez -tez iste'mol qilish sog'liq muammolariga olib kelmasligi kerak. S vitamini qo'shimchalari orqali haddan tashqari ko'p iste'mol qilish yon ta'sirga olib kelishi mumkin.

Kattalar uchun tavsiya etilgan S vitamini miqdori erkaklar uchun 90 milligramm (ayollar uchun) 75 mg ni tashkil qiladi.

Kuniga 2000 mg dan ortiq S vitamini qabul qilgan kattalar yon ta'sirga duch kelishi mumkin.

Agar odam tavsiya etilgan S vitamini miqdoridan oshsa, ovqat hazm qilish tizimining engil buzilishi bo'lishi mumkin. Agar tanada so'rilmaydigan C vitamini oshqozon -ichak traktini bezovta qilsa, bu sodir bo'lishi mumkin.

S vitaminining haddan tashqari ko'p uchraydigan engil yon ta'siriga quyidagilar kiradi:

Tana qo'shimchalardan olingan barcha S vitamini o'zlashtirmaydi.

Masalan, agar odam har kuni 30–180 mg S vitamini qabul qilsa, uning tanasi bu vitaminning 70-90 foizini o'zlashtiradi. Agar odam kuniga 1 grammdan ortiq S vitamini qabul qilsa, organizm vitaminning 50 foizidan kamini o'zlashtiradi, bu esa salbiy yon ta'sir xavfini kamaytiradi. Ortiqcha tanani siydikda qoldiradi.

Agar odam haddan tashqari ko'p iste'mol qilsa, S vitamini yoqimsiz simptomlarni keltirib chiqarishi mumkin, shuning uchun Oziq -ovqat va ovqatlanish kengashi "ruxsat etilgan yuqori iste'mol darajasini" o'rnatdi.

Oziq -ovqat qo'shimchalari idorasi (ODS) ma'lumotlariga ko'ra, 19 yoshdan oshgan odamlarda S vitamini qabul qilishning yuqori chegarasi erkak va ayollarda 2000 mg ni tashkil qiladi. Homilador va emizikli ayollar uchun chegara o'zgarmaydi.

Bolalar va chaqaloqlar uchun kunlik C vitaminining yuqori darajasi quyidagicha:

  • 1-3 yoshli chaqaloqlar uchun 400 mg
  • 4-8 yoshli bolalar uchun 650 mg
  • 9-13 yoshdagi bolalar uchun 1200 mg
  • 14-18 yoshdagi o'smirlar uchun 1800 mg
  • 14-18 yoshli homilador yoki emizikli o'smirlarda 1800 mg

Bu cheklovlarga istisnolar bor, ular faqat shifokor boshqa dozani ko'rsatmagan bo'lsa qo'llaniladi. Ba'zi odamlar tibbiy davolanish uchun ko'proq miqdorda S vitamini qabul qilishlari mumkin.

Kamdan -kam hollarda, odamlar S vitamini ko'p qabul qilishda jiddiy yon ta'sirga duch kelishi mumkin.

S vitamini haddan tashqari ko'p iste'mol qilish sog'liq uchun mumkin bo'lgan xavflarni o'z ichiga oladi:

Buyrak toshlari

Shifokorlarning fikricha, agar S vitamini ko'p miqdorda iste'mol qilinsa, odam siydikda oksalat va siydik kislotasi birikmalarini chiqarib yuborishi mumkin. Bu birikmalar buyrak toshining shakllanishiga olib kelishi mumkin.

Jurnaldagi amaliy ish mualliflari Buyrak xalqarobir ayol 4 oy davomida har kuni 4 g yoki undan ko'p S vitamini qabul qilganidan keyin buyrak toshlari paydo bo'lganini xabar qildi.

Biroq, tadqiqotchilar S vitamini qabul qilish va buyrak toshlarining shakllanishi bo'yicha katta miqyosli tadqiqotlar o'tkazmaganlar. ODS ma'lumotlariga ko'ra, buyrak toshlari bo'lgan odamlar, agar ular ko'p miqdorda S vitamini qabul qilsalar, ularni hosil qilish ehtimoli ko'proq.

Oziq moddalar muvozanati

S vitamini haddan tashqari ko'p iste'mol qilish bilan bog'liq yana bir tashvish shundaki, u organizmning boshqa ozuqaviy moddalarni qayta ishlash qobiliyatiga putur etkazishi mumkin.

Masalan, S vitamini tanadagi B-12 vitamini va mis miqdorini kamaytirishi mumkin.

S vitaminining mavjudligi, shuningdek, organizmda temirning so'rilishini kuchaytirishi mumkin, bu esa haddan tashqari yuqori darajaga olib kelishi mumkin.

Suyak toshmalariga sabab bo'ladi

Artrit jamg'armasi ma'lumotlariga ko'ra, bir tadqiqot shuni ko'rsatdiki, organizmda juda ko'p miqdordagi S vitamini borligi, odamda suyak og'riqlari paydo bo'lish ehtimolini oshiradi.

Shu bilan birga, Fond, shuningdek, C vitamini darajasi past bo'lgan odamlarda bo'g'imlarning og'riqli yallig'lanishi bo'lgan revmatoid artritga chalinish xavfi yuqori ekanligini aniqlagan tadqiqotga iqtibos keltirdi.

Bu topilmalar S vitamini qo'shimchalari zarurligini ta'kidlaydi, bu na ko'p, na juda kam.

Niatsin-simvastatin samaradorligini pasaytiring

Dalillar shuni ko'rsatadiki, S vitamini qo'shimchalarini qabul qilish, niatsin-simvastatin kombinatsiyalangan dori-darmonlarni qabul qilgan odamlarda, yuqori zichlikdagi lipoprotein (HDL) xolesterinini oshirish qobiliyatini pasaytirishi mumkin. Bu dori niatsin vitaminini statin simvastatin (Zocor) bilan birlashtiradi va odamlar uni yuqori xolesterinni davolash uchun qabul qilishadi.

Shifokorlar HDL xolesterolini "yaxshi" xolesterin deb hisoblashadi, chunki u qondagi zararli xolesterin miqdorini kamaytiradi.

Agar biror kishi S vitamini qo'shimchalari va niatsin-simvastatinni qabul qilsa, u har biri samaraliroq bo'lishi uchun shifokor bilan gaplashishi kerak. Shifokorlar S vitamini Zokorga o'xshash boshqa dorilarning qobiliyatiga ta'sir qiladimi yoki yo'qligini bilishmaydi.

Inson tanasi S vitamini ishlab chiqara olmaydi, shuning uchun odamlar kundalik ehtiyojlarini qondirish uchun S vitamini o'z ichiga olgan ovqatlarni iste'mol qilishlari kerak. Agar kimdir S vitamini etishmasligi xavfi ostida bo'lsa, u S vitamini qo'shimchalarini olishi mumkin.

ODS har kuni quyidagi S vitamini RDA miqdorini belgilashni maslahat beradi:

YoshiErkakAyol
1-3 yil15 mg15 mg
4-8 yil25 mg25 mg
9-13 yoshda45 mg45 mg
14-18 yoshda75 mg65 mg
19+ yil90 mg75 mg

Sigaret chekadiganlar chekmaydiganlarga qaraganda kuniga 35 mg ko'proq S vitamini qabul qilishlari kerak.

Homiladorlik paytida yoki emizish paytida ayollar kuniga C vitaminining quyidagi darajasini olishlari kerak:

  • 14-18 yosh: homiladorlik paytida 80 mg va emizishda 115 mg
  • 19 yoshdan katta: homiladorlik paytida 85 mg va emizishda 120 mg

1 yoshgacha bo'lgan bolalarda S vitamini uchun RDA ni taklif qilish uchun etarli tadqiqotlar yo'q. Natijada, ODS "etarli iste'mol" ni ta'minlaydi, bu etarli bo'lishi mumkin bo'lgan miqdor:

Masalan, S vitamini tanadagi B-12 vitamini va mis miqdorini kamaytirishi mumkin.

S vitaminining mavjudligi, shuningdek, organizmda temirning so'rilishini kuchaytirishi mumkin, bu esa haddan tashqari yuqori darajaga olib kelishi mumkin.

Suyak toshmalariga sabab bo'ladi

Artrit jamg'armasi ma'lumotlariga ko'ra, bir tadqiqot shuni ko'rsatdiki, organizmda juda ko'p miqdordagi S vitamini borligi, odamda suyak og'riqlari paydo bo'lish ehtimolini oshiradi.

Shu bilan birga, Jamg'arma, shuningdek, C vitamini darajasi past bo'lgan odamlarda bo'g'imlarning og'riqli yallig'lanish kasalligi bo'lgan revmatoid artrit rivojlanish xavfi yuqori ekanligi aniqlangan tadqiqotga iqtibos keltirdi.

Bu topilmalar S vitamini qo'shimchalari zarurligini ta'kidlaydi, bu na ko'p, na juda kam.

Niatsin-simvastatin samaradorligini pasaytiring

Dalillar shuni ko'rsatadiki, S vitamini qo'shimchalarini qabul qilish, niatsin-simvastatin kombinatsiyalangan dori-darmonlarni qabul qilgan odamlarda, yuqori zichlikdagi lipoprotein (HDL) xolesterinini oshirish qobiliyatini pasaytirishi mumkin. Bu dori niatsin vitaminini statin simvastatin (Zocor) bilan birlashtiradi va odamlar uni yuqori xolesterinni davolash uchun qabul qilishadi.

Shifokorlar HDL xolesterolini "yaxshi" xolesterin deb hisoblashadi, chunki u qondagi zararli xolesterin miqdorini kamaytiradi.

Agar biror kishi S vitamini qo'shimchalari va niatsin-simvastatinni qabul qilsa, u har biri samaraliroq bo'lishi uchun shifokor bilan gaplashishi kerak. Shifokorlar S vitamini Zokorga o'xshash boshqa dorilarning qobiliyatiga ta'sir qiladimi yoki yo'qligini bilishmaydi.

Inson tanasi S vitamini ishlab chiqara olmaydi, shuning uchun odamlar kundalik ehtiyojlarini qondirish uchun S vitamini o'z ichiga olgan ovqatlarni iste'mol qilishlari kerak. Agar kimdir S vitamini etishmasligi xavfi ostida bo'lsa, u S vitamini qo'shimchalarini olishi mumkin.

ODS har kuni quyidagi S vitamini RDA miqdorini belgilashni maslahat beradi:

YoshiErkakAyol
1-3 yil15 mg15 mg
4-8 yil25 mg25 mg
9-13 yoshda45 mg45 mg
14-18 yoshda75 mg65 mg
19+ yil90 mg75 mg

Sigaret chekadiganlar chekmaydiganlarga qaraganda kuniga 35 mg ko'proq S vitamini qabul qilishlari kerak.

Homiladorlik paytida yoki emizish paytida ayollar kuniga C vitaminining quyidagi darajasini olishlari kerak:

  • 14-18 yosh: homiladorlik paytida 80 mg va emizishda 115 mg
  • 19 yoshdan katta: homiladorlik paytida 85 mg va emizishda 120 mg

1 yoshgacha bo'lgan bolalarda S vitamini uchun RDA ni taklif qilish uchun etarli tadqiqotlar yo'q. Natijada, ODS "etarli iste'mol" ni ta'minlaydi, bu etarli bo'lishi mumkin bo'lgan miqdor:


Agar siz S vitamini ko'p iste'mol qilsangiz nima bo'ladi?

S vitamini odatda yuqori dozalarda ham xavfsiz qabul qilinadi. Biroq, odamlar ba'zida ovqat hazm qilish bezovtalanishi kabi engil yon ta'sirga duch kelishi mumkin. Kamdan kam hollarda jiddiyroq yon ta'siri paydo bo'lishi mumkin.

S vitamini - inson tanasi uchun zarur bo'lgan vitamin. Bu antioksidant bo'lib, u qon bosimini pasaytirish, yallig'lanish bilan kurashish va kollagen hosil qilish kabi bir qator muhim jarayonlarga yordam beradi.

Ushbu maqolada biz S vitamini iste'mol qilishning tavsiya etilgan yuqori chegaralarini, haddan tashqari dozani qabul qilishning mumkin bo'lgan yon ta'sirini va boshqa ogohlantirishlarni ko'rib chiqamiz.

Pinterest -da bo'lishish odatda S vitamini yuqori bo'lgan taomlarni tez -tez iste'mol qilish xavfsizdir.

S vitamini yuqori bo'lgan ovqatlarni tez -tez iste'mol qilish sog'liq muammolariga olib kelmasligi kerak. S vitamini qo'shimchalar orqali ko'p iste'mol qilish yon ta'sirga olib kelishi mumkin.

Kattalar uchun tavsiya etilgan S vitamini miqdori erkaklar uchun 90 milligramm (ayollar uchun) 75 mg ni tashkil qiladi.

Kuniga 2000 mg dan ortiq S vitamini qabul qilgan kattalar yon ta'sirga duch kelishi mumkin.

Agar odam tavsiya etilgan S vitamini miqdoridan oshsa, ovqat hazm qilish tizimining engil buzilishi bo'lishi mumkin. Agar tanada so'rilmaydigan C vitamini oshqozon -ichak traktini bezovta qilsa, bu sodir bo'lishi mumkin.

S vitaminining haddan tashqari ko'p uchraydigan engil yon ta'siriga quyidagilar kiradi:

Tana qo'shimchalardan olingan barcha S vitamini o'zlashtirmaydi.

Masalan, agar odam har kuni 30–180 mg S vitamini qabul qilsa, uning tanasi bu vitaminning 70-90 foizini o'zlashtiradi. Agar odam kuniga 1 grammdan ortiq S vitamini qabul qilsa, organizm vitaminning 50 foizidan kamini o'zlashtiradi, bu esa salbiy ta'sirlar xavfini kamaytiradi. Ortiqcha tanani siydikda qoldiradi.

Agar odam haddan tashqari ko'p iste'mol qilsa, S vitamini yoqimsiz simptomlarni keltirib chiqarishi mumkin, shuning uchun Oziq -ovqat va ovqatlanish kengashi "ruxsat etilgan yuqori iste'mol darajasini" o'rnatdi.

Oziq -ovqat qo'shimchalari idorasi (ODS) ma'lumotlariga ko'ra, 19 yoshdan oshgan odamlarda S vitamini qabul qilishning yuqori chegarasi erkak va ayollarda 2000 mg ni tashkil qiladi. Homilador va emizikli ayollar uchun chegara o'zgarmaydi.

Bolalar va chaqaloqlar uchun kunlik C vitaminining yuqori darajasi quyidagicha:

  • 1-3 yoshli chaqaloqlar uchun 400 mg
  • 4-8 yoshli bolalar uchun 650 mg
  • 9-13 yoshdagi bolalar uchun 1200 mg
  • 14-18 yoshdagi o'smirlar uchun 1800 mg
  • 14-18 yoshli homilador yoki emizikli o'smirlarda 1800 mg

Bu cheklovlarga istisnolar bor, ular faqat shifokor boshqa dozani ko'rsatmagan bo'lsa qo'llaniladi. Ba'zi odamlar tibbiy davolanish uchun ko'proq miqdorda S vitamini qabul qilishlari mumkin.

Kamdan -kam hollarda, odamlar S vitamini ko'p qabul qilishda jiddiy yon ta'sirga duch kelishi mumkin.

S vitamini haddan tashqari ko'p iste'mol qilish sog'liq uchun mumkin bo'lgan xavflarni o'z ichiga oladi:

Buyrak toshlari

Shifokorlarning fikricha, agar S vitamini ko'p miqdorda iste'mol qilinsa, odam siydikda oksalat va siydik kislotasi birikmalarini chiqarib yuborishi mumkin. Bu birikmalar buyrak toshining shakllanishiga olib kelishi mumkin.

Jurnaldagi amaliy ish mualliflari Buyrak xalqarobir ayol 4 oy davomida har kuni 4 g yoki undan ko'p S vitamini qabul qilganidan keyin buyrak toshlari paydo bo'lganini xabar qildi.

Biroq, tadqiqotchilar S vitamini qabul qilish va buyrak toshlarining shakllanishi bo'yicha katta miqyosli tadqiqotlar o'tkazmaganlar. ODS ma'lumotlariga ko'ra, buyrak toshlari bo'lgan odamlar, agar ular ko'p miqdorda S vitamini qabul qilsalar, ularni hosil qilish ehtimoli ko'proq.

S vitamini haddan tashqari ko'p iste'mol qilish sog'liq uchun mumkin bo'lgan xavflarni o'z ichiga oladi:

Buyrak toshlari

Doctors believe that too much vitamin C supplementation could result in a person excreting the compounds oxalate and uric acid in their urine. These compounds could lead to kidney stone formation.

The authors of a case study in the journal Kidney Internationalreported that a woman developed kidney stones after taking 4 g or more of vitamin C each day for 4 months.

However, researchers have not conducted any larger scale studies on vitamin C intake and kidney stone formation. They do know that people who have a history of kidney stones are more likely to form them if they take large amounts of vitamin C, according to the ODS .

Nutrient imbalances

Another concern regarding excessive vitamin C intake is that it can impair the body’s ability to process other nutrients.

For example, vitamin C may reduce the levels of vitamin B-12 and copper in the body.

The presence of vitamin C can also enhance iron absorption in the body, which could lead to excessively high levels.

Cause bone spurs

According to the Arthritis Foundation, one study found that the presence of very high vitamin C levels in the body increased the likelihood of a person developing painful bone spurs.

However, the Foundation also cited a research study that found that people with low levels of vitamin C had a higher risk of developing rheumatoid arthritis, a painful inflammatory joint condition.

These findings emphasize the need for appropriate vitamin C supplementation that provides neither too much nor too little.

Impair the effectiveness of niacin-simvastatin

Evidence suggests that taking vitamin C supplements may impair the body’s ability to increase high density lipoprotein (HDL) cholesterol in people taking the combination drug niacin-simvastatin. This drug combines the vitamin niacin with the statin simvastatin (Zocor), and people take it to treat high cholesterol.

Doctors consider HDL cholesterol the “good” cholesterol because it reduces the amount of harmful cholesterol in the blood.

If a person takes vitamin C supplements and niacin-simvastatin, they should talk to their doctor about ways to make each more effective. Doctors do not know whether vitamin C also affects the ability of other medicines similar to Zocor.

A person’s body cannot make vitamin C, so people need to eat enough foods that contain vitamin C to meet their daily needs. If someone is at risk of a vitamin C deficiency, they can take vitamin C supplements.

The ODS advise aiming for the following RDA of vitamin C each day:

YoshiErkakAyol
1–3 years15 mg15 mg
4–8 years25 mg25 mg
9–13 years45 mg45 mg
14–18 years75 mg65 mg
19+ years90 mg75 mg

People who smoke should take 35 mg more vitamin C per day than those who do not smoke.

During pregnancy or when breastfeeding, women should get the following levels of vitamin C per day:

  • 14–18 years: 80 mg during pregnancy and 115 mg when breastfeeding
  • 19 years and older: 85 mg during pregnancy and 120 mg when breastfeeding

There is not enough research to suggest an RDA for vitamin C in those younger than 1 year of age. As a result, the ODS provide an “adequate intake,” which is the amount that is likely to be sufficient:


What happens when you take too much vitamin C?

Vitamin C is usually safe to take even at high dosages. However, people may sometimes experience mild side effects, such as digestive discomfort. Rarely, more serious side effects can occur.

Vitamin C is an essential vitamin for the human body. It is an antioxidant, and it helps with a range of important processes, including lowering blood pressure, fighting inflammation, and creating collagen.

In this article, we look at the recommended upper limits of vitamin C intake, possible side effects of taking too much, and other warnings.

Share on Pinterest It is usually safe to frequently eat foods high in vitamin C.

Frequently eating foods high in vitamin C should not lead to any health issues. Taking too much vitamin C through supplements can, however, cause side effects.

In adults, the recommended dietary allowance (RDA) of vitamin C is 90 milligrams (mg) for males and 75 mg for females.

Adults who take more than 2,000 mg of vitamin C per day may experience side effects.

When a person takes more than the recommended limit of vitamin C, they may experience mild digestive disturbances. These can occur if the vitamin C that the body does not absorb irritates the gastrointestinal tract.

Common mild side effects of too much vitamin C include:

The body does not absorb all of the vitamin C that it gets from supplements.

For example, if a person takes 30–180 mg of vitamin C each day, their body absorbs about 70–90% of this vitamin. If a person takes more than 1 gram (g) of vitamin C per day, the body absorbs less than 50% of the vitamin, which reduces the risk of negative side effects. The excess leaves the body in the urine.

As vitamin C can cause unpleasant symptoms if a person takes too much, the Food and Nutrition Board have established “tolerable upper intake levels.”

According to the Office of Dietary Supplements (ODS) , the upper limit for vitamin C intake in people aged 19 years and over is 2,000 mg in males and females. The limit remains the same for pregnant or breastfeeding women.

The upper daily vitamin C levels for children and infants are as follows:

  • 400 mg for infants aged 1–3 years
  • 650 mg for children aged 4–8 years
  • 1,200 mg for children aged 9–13 years
  • 1,800 mg for teenagers aged 14–18 years
  • 1,800 mg in pregnant or breastfeeding teenagers aged 14–18 years

There are exceptions to these limits, which only apply if a person’s doctor has not specified a different intake. Some people may have to take larger amounts of vitamin C for medical treatments.

Less commonly, people may experience severe side effects from taking too much vitamin C. Long term intake above the recommended levels increases the risk of these negative effects.

Possible health risks of taking too much vitamin C include:

Kidney stones

  • 14–18 years: 80 mg during pregnancy and 115 mg when breastfeeding
  • 19 years and older: 85 mg during pregnancy and 120 mg when breastfeeding

There is not enough research to suggest an RDA for vitamin C in those younger than 1 year of age. As a result, the ODS provide an “adequate intake,” which is the amount that is likely to be sufficient:


What happens when you take too much vitamin C?

Vitamin C is usually safe to take even at high dosages. However, people may sometimes experience mild side effects, such as digestive discomfort. Rarely, more serious side effects can occur.

Vitamin C is an essential vitamin for the human body. It is an antioxidant, and it helps with a range of important processes, including lowering blood pressure, fighting inflammation, and creating collagen.

In this article, we look at the recommended upper limits of vitamin C intake, possible side effects of taking too much, and other warnings.

Share on Pinterest It is usually safe to frequently eat foods high in vitamin C.

Frequently eating foods high in vitamin C should not lead to any health issues. Taking too much vitamin C through supplements can, however, cause side effects.

In adults, the recommended dietary allowance (RDA) of vitamin C is 90 milligrams (mg) for males and 75 mg for females.

Adults who take more than 2,000 mg of vitamin C per day may experience side effects.

When a person takes more than the recommended limit of vitamin C, they may experience mild digestive disturbances. These can occur if the vitamin C that the body does not absorb irritates the gastrointestinal tract.

Common mild side effects of too much vitamin C include:

The body does not absorb all of the vitamin C that it gets from supplements.

For example, if a person takes 30–180 mg of vitamin C each day, their body absorbs about 70–90% of this vitamin. If a person takes more than 1 gram (g) of vitamin C per day, the body absorbs less than 50% of the vitamin, which reduces the risk of negative side effects. The excess leaves the body in the urine.

As vitamin C can cause unpleasant symptoms if a person takes too much, the Food and Nutrition Board have established “tolerable upper intake levels.”

According to the Office of Dietary Supplements (ODS) , the upper limit for vitamin C intake in people aged 19 years and over is 2,000 mg in males and females. The limit remains the same for pregnant or breastfeeding women.

The upper daily vitamin C levels for children and infants are as follows:

  • 400 mg for infants aged 1–3 years
  • 650 mg for children aged 4–8 years
  • 1,200 mg for children aged 9–13 years
  • 1,800 mg for teenagers aged 14–18 years
  • 1,800 mg in pregnant or breastfeeding teenagers aged 14–18 years

There are exceptions to these limits, which only apply if a person’s doctor has not specified a different intake. Some people may have to take larger amounts of vitamin C for medical treatments.

Less commonly, people may experience severe side effects from taking too much vitamin C. Long term intake above the recommended levels increases the risk of these negative effects.

Possible health risks of taking too much vitamin C include:

Kidney stones

Doctors believe that too much vitamin C supplementation could result in a person excreting the compounds oxalate and uric acid in their urine. These compounds could lead to kidney stone formation.

The authors of a case study in the journal Kidney Internationalreported that a woman developed kidney stones after taking 4 g or more of vitamin C each day for 4 months.

However, researchers have not conducted any larger scale studies on vitamin C intake and kidney stone formation. They do know that people who have a history of kidney stones are more likely to form them if they take large amounts of vitamin C, according to the ODS .

Nutrient imbalances

Another concern regarding excessive vitamin C intake is that it can impair the body’s ability to process other nutrients.

For example, vitamin C may reduce the levels of vitamin B-12 and copper in the body.

The presence of vitamin C can also enhance iron absorption in the body, which could lead to excessively high levels.

Cause bone spurs

According to the Arthritis Foundation, one study found that the presence of very high vitamin C levels in the body increased the likelihood of a person developing painful bone spurs.

However, the Foundation also cited a research study that found that people with low levels of vitamin C had a higher risk of developing rheumatoid arthritis, a painful inflammatory joint condition.

These findings emphasize the need for appropriate vitamin C supplementation that provides neither too much nor too little.

Impair the effectiveness of niacin-simvastatin

Evidence suggests that taking vitamin C supplements may impair the body’s ability to increase high density lipoprotein (HDL) cholesterol in people taking the combination drug niacin-simvastatin. This drug combines the vitamin niacin with the statin simvastatin (Zocor), and people take it to treat high cholesterol.

Doctors consider HDL cholesterol the “good” cholesterol because it reduces the amount of harmful cholesterol in the blood.

If a person takes vitamin C supplements and niacin-simvastatin, they should talk to their doctor about ways to make each more effective. Doctors do not know whether vitamin C also affects the ability of other medicines similar to Zocor.

A person’s body cannot make vitamin C, so people need to eat enough foods that contain vitamin C to meet their daily needs. If someone is at risk of a vitamin C deficiency, they can take vitamin C supplements.

The ODS advise aiming for the following RDA of vitamin C each day:

YoshiErkakAyol
1–3 years15 mg15 mg
4–8 years25 mg25 mg
9–13 years45 mg45 mg
14–18 years75 mg65 mg
