Vitamins are the nutrients necessary to fulfill many essential functions of the body. According to Medlineplus, there are 13 vitamins that you must cultivate and develop normally, including vitamins A and E.
It is ideal to obtain these essential vitamins from the food you eat, but it can sometimes be difficult for a number of reasons.
Taking daily multivitamin is a way to make sure you get enough vitamin. However, overconsumption vitamins can be toxic. They can also interact with certain medications or medical conditions.
Consult your doctor to take a multivitamin and if you should consider multivitamins without vitamins A and E.
Vitamin A
“Vitamin A” is the umbrella term for a group of compounds that include retinol, retinyl esters, beta-carotene, alpha-carotene and beta-co-cryptoxanthin, according to the National Institutes of Health (NIH).
Vitamin A is a soluble fatty vitamin. It has an important role in vision, reproduction, immune function and cell growth.
The daily value (DV) of vitamin A is 900 micrograms (MCG) equivalent of retinol activity (RAE). Foods containing vitamin A include:
- Sweet potato
- Spinach
- Carrots
- herring
- Enriched skimmed milk
- Cantaloupe
- Red peppers
- Mango
According to the Memorial Sloan Kettering Cancer Center, vitamin A supplements interact with certain drugs that can be toxic to the liver. Supplementation is also contraindicated with chronic alcohol consumption, liver and pregnant lesions.
Vitamin E
Vitamin E is vitamin and antioxidant of fat, says the NIH. The name, like vitamin A, is also an umbrella term for its different forms. The alpha-tocopherol is the only form of vitamin E which however meets the needs of your body.
The antioxidant effects of vitamin E help protect your cells from damage. It also has a role in immune function. In addition, vitamin E can inhibit platelet aggregation and may therefore help prevent the formation of blood clots.
Vitamin E DV is 15 milligrams (MG). Vitamin E is found in foods such as:
- Wheat germ
- Seeds and nuts
- Spinach
- Broccoli
- Kiwi
- Some oils
According to the Memorial Sloan Kettering Cancer Center, high blood serum rates of vitamin E which can result from supplementation interact with warfarin (coumadin) and other anticoagulants.
It is also not known whether to take supplements containing vitamin E or other antioxidants during chemotherapy or radiotherapy can reduce or cancel their effects.
If you are undergoing these therapies and you care about your vitamin E or another antioxidant intake, especially in the form of a supplement, talk to your doctor.
Multivitamins without vitamin A
According to the Merck Manual, adults who consume more than 1,500 mcg rae per day can develop chronic toxicity of vitamin A. Megadoses of vitamin A can also lead to hepatic toxicity.
Eating excessive quantities of food with carotenes will not lead to the toxicity of vitamin A, but it can turn your yellow skin.
Symptoms of toxicity vary but generally include headache and rash. The acute toxicity of the ingestion of massive quantities of vitamin A is extremely rare in adults, but is more frequent when children accidentally ingest large quantities of supplements.
Symptoms of acute toxicity include nausea, vomiting, abdominal pain, drowsiness, irritability and increased pressure in the skull.
Chronic toxicity by ingesting a lot of vitamin A over a longer period can initially cause coarse hair, loss of eyebrow hair, dry and rough skin, dry eyes and cracked lips.
Later, symptoms include serious headaches, pressure in the skull and generalized weakness. The bones weakened by the chronic toxicity of vitamin A can also ensure that fractures occur easily.
Although they can be difficult to find, you can buy a multivitamin without vitamin A, although it will probably still contain vitamin E.
Here are all multivitamins without vitamin A:
Multivitamins without vitamin E
Consumption too much vitamin E can also cause toxicity. The upper limit of vitamin E consumption per day is 1,000 mg, according to the Merck manual.
Many adults take large doses of 400 mg to 800 mg per day for months without side effects. Sometimes nausea, diarrhea, fatigue and muscle weakness occur at such doses.
The most serious result of the toxicity of vitamin E is coagulation and bleeding of altered blood. This is rare in doses of less than 1,000 mg, unless you also take a blood medication.
According to the Linus Pauling Institute, some doctors recommend stopping the vitamin E high -dose supplementation two to four weeks before surgery to reduce the risk of hemorrhage.
To avoid overconsumption, you can buy a multivitamin without vitamin E, although most brands without it always contain vitamin A.
Versions that do not have vitamin E include:
