The industry of dietary supplements is a growing multi-billion dollar business which grows every year. As of the year 2011, the consumer sales reached $30 billion and it increased by 8%. Over half of the US adults are taking a dietary supplement, as said by the CDC or Center for Disease Control & Prevention. About 85% of the elite track and field athletes are taking supplements.
Oftentimes, claims are made regarding those supplements that are marketed to athletes. They are claimed to change the composition of the body, prolong fatigue and enhance performance. Others are claimed to develop physical or mental functions, boost energy and support your overall health.
Some supplements might have some beneficial effects, whilst some others do not have effect at all while others have ingredients which might actually impair health and performance. Likewise, significant are potential detrimental impacts of taking supplements at inadequate dose. Whilst most dietary supplements, like vitamins and minerals, have a countenance the same with prescription or through the counter medicines, understand that such products aren’t regulated in similar way.
Since 1994, the DSHEA or Dietary Supplement Health & Education Act regulated dietary supplements with the labeling guidelines, yet the content’s effectiveness, safety and quality isn’t covered. Rather, it’s left up to the consumers to arrive at such determinations. Taking multivitamins is a convenient, easy and generally cheap way of supplementing nutrients which might be missing from your diet.
Some research recommends that using the multivitamin routinely could help to prevent cardiovascular disease or cancer. Multivitamin intake is likely unnecessary for a runner that regularly consumes a healthy diet, specifically if it involves high calories. More foods mean more minerals and vitamins with supplementary nutrients coming from those fortified products.
Factors which increase deficiency risk for the athletes which include:
- Consuming less than 1,500 calories each day
- Food allergic reactions, restrictions and intolerances which restrict food ingestion or gastrointestinal tract absorption
- A vegetarian or vegan diet low in vitamins such as vitamin D, B2 and B12 including minerals like zinc and iron that could necessitate supplementation.
For prevention of CVD and cancer, health professionals do come with different interpretations of the multivitamin research and that is the reason why daily nutrient suggestions differ. When you prefer to take a multivitamin, you should consider the following:
- More is not better – search for the supplement which contains 100% of the needed vitamins and minerals daily value. Avoid intake of mega dosages which is higher than the recommended dose that could be unsafe, specifically fat-soluble vitamins that the body retains.
- When you’re deficient in a vitamin or mineral, you must consider supplementing with that nutrient since most vitamins & minerals are competing for absorption. The most typical individual vitamins or minerals which are advantageous to take as supplements are calcium, iron & vitamin D. When you’re taking any other medicines and dietary supplements, you must talk about the addition of another multivitamin together with your physician or pharmacist.
You must ignore supplements that have been supported by testimonials. Rather, search for those that were backed by scientific studies that were rigorously executed. You should not buy anything within the label which does not provide a listing of ingredients which include the term known as “proprietary blend”. The product might not be standardized to a constant dosage and it might contain unsafe or illegal substances.
