Vitamins and Supplements UK
Our bodies require vitamins and supplements UK to function properly. There are five vitamins known: A, C, D, and E. The B vitamins are thiamin, riboflavin, niacin, pantothenic acids (B3) and pyridoxal, (B6), cobalamin, B12, biotin, and folate/Folic Acid. Many minerals are vital for our health, including calcium, phosphorus, and potassium as well as magnesium, iron, zinc (B1), riboflavin (B2), pantothenic acid (B5), pyridoxal(B12), cobalamin, folate/folic acid (B12), and cobalt. The Dietary Guidelines suggest that individuals should strive to satisfy their nutritional needs through healthy eating patterns that include nutrient-dense foods.
Multivitamins/multiminerals (MVMs) are the most frequently used dietary supplements, with close to half of American adults taking them. MVMs can’t replace a varied diet that includes healthy foods. Foods offer more than Vitamins and Supplements UK. Many foods contain fiber and other nutrients that can have health benefits. Some people may be able to benefit from single-nutrient or multivitamin supplements. There is limited evidence supporting their use in general health and prevention.
- A healthy diet of nutrient-dense foods can help most people get all the vitamins and minerals they need. The Dietary Guidelines offer recommendations for certain populations, such as women who may become pregnant or breastfeed and those over 50.
- An MVM can increase nutrient intake, and help some people get the required amounts of Vitamins and Supplements UK from food. An MVM can increase the risk of getting too many nutrients like iron, vitamin A and zinc. This is especially true if a person consumes more than a simple, daily product that provides 100 percent or less of the daily value (DV).
- Age-Related Eye Disease Study, (AREDS), was conducted by NIH’s National Eye Institute. It concluded in 2001 that high daily intakes of vitamins C, E, beta-carotene, and the minerals copper–the AREDS formulation–can slow down the progression to advanced age-related Macular Degeneration (AMD), a fatal eye disease.
- The AREDS2 study later showed that removing beta carotene from AREDS didn’t reduce its protection against advanced AMD. AREDS2 also found that the addition of lutein/zeaxanthin and omega-3 fatty acid to the original AREDS formulation did not affect the need for cataract surgery.
- There is no set standard or regulatory requirement for MVMs or any other dietary supplement as to the amount or quality of nutrients they should contain. Manufacturers decide which vitamins, minerals, or other ingredients they want to include in their products. The United States doesn’t require dietary supplements to be standardized. They must have a Supplement Facts label with an ingredient list that describes what they contain.
- To identify MVMs in your supplement products, read the Supplement Facts label. To find out how much of your daily allowance you are getting, make sure to look at the percent daily value (%DV).
- Supplements can be more beneficial for people who have healthier lifestyles and eat better. MVMs don’t prevent chronic diseases, but there is no evidence to support this claim.
- A daily intake of a simple MVM is unlikely not to pose any health risks for most people. If you consume foods or beverages with added vitamins and minerals, such as cereals, drinks with vitamins and minerals, it is important to ensure that you do not exceed the safe upper limit for nutrients. To determine if your DV is higher than 100%, check the Nutrition Facts label on packaged foods and the Supplement Facts label for MVMs. For more information on safe upper levels of nutrients, visit the NIH Office of Dietary Supplements at: ods.od.nih.gov/factsheets/list-all.
- Smokers and ex-smokers should stay away from MVM products with more than 100% DV of vitamin A. These MVM products can be either performed retinol, beta-carotene, or a combination of both. Two studies have shown that high supplemental intakes of these nutrients are linked to an increased risk for lung cancer in smokers.
- Excessive intake of vitamin A (preformed, retinol form) during pregnancy is linked to an increased risk of birth defects.
- Adult males and women postmenopausal should not take iron supplements, or MVMs that contain more than the recommended daily allowance of iron (8 mg/day), unless they are diagnosed with iron deficiency, inadequacy or severe illness. Pregnant women, teenage girls, infants, older children, and women in childbearing years may benefit from iron supplements. Iron supplements can cause poisoning in young children. Parents and guardians should ensure that iron-containing supplements are out of reach of children.
- MVMs that provide nutrients up to 100% DV are not known to interact with medication. Talk to your doctor if you are taking a blood thinner such as warfarin (Coumadin) or other brands. Before you start any MVM, dietary supplement, or MVM that contains vitamin K. Doctors base the medicine’s dosage partly on how much vitamin K is consumed in food and supplement foods.
