Vitamin Supplements – Do They Work?
Vitamin Supplements – Do They Work?
Vitamin Supplementation is huge worldwide. Most of us take vitamins now or have taken vitamins in the past. The US ranks top in dietary supplementation globally. 18.9% of Americans had taken at least one dietary supplement in 2004. Over 100 million Americans use vitamin and mineral supplements everyday. The global market has become a multi-billion dollar industry and the dietary supplement sector is growing the fastest.
The most common reason for supplement use is “to improve overall health and general well being.” It is a popular belief that vitamins are antioxidants and can therefore protect us from oxidative stress that causes many health conditions.
The most common supplements taken are:
multivitamin/multiminerals – 22%;
multivitamins plus vitamin C – 15%;
vitamin C as a single vitamin – 13%;
herbal and botanical supplements – 7%;
vitamin E as a single vitamin – 6%.
Over the years, more and more reports on the health benefits of vitamin supplements have emerged, ranging from cardiovascular benefits to cancer prevention. This is mainly due to the antioxidant properties of vitamins that can protect us from oxidative stress. As a result several studies have been conducted to confirm these reports. Some of the latest studies summarized below reveal surprising results to say the least.
One of the very first studies to comprehensively investigate the health effects of vitamin supplements was conducted by Danish researchers in 2007. They performed a meta-analysis on data pooled from several clinical trials which used supplementation of the antioxidant vitamin A, vitamin E, beta-carotene, vitamin C and selenium used as stand-alone or as combination supplements to treat a wide range of health conditions, from cardiovascular disorders to cancer. Their results were a surprising, even troubling. For one, no benefits of these “antioxidant supplements” were found. Second, supplementation with vitamins A and E and beta-carotene (but not vitamin C and selenium) actually increased overall mortality. This study prompted other researchers to take a second look at the benefits of vitamin supplements.
In a more recent review paper, the same researchers performed another meta-analysis of more data from several clinical trials, this time involving over 200,000 people who are healthy as well as those with existing health conditions. The researchers only considered studies which compared the efficacy of antioxidant supplements against placebos in the primary and secondary prevention of different medical conditions. The authors reported that they “found no evidence to support antioxidant supplements for primary or secondary prevention. Vitamin A, beta-carotene, and vitamin E may increase mortality.”
Another meta-analysis investigated the anti-cancer properties of antioxidant supplements, particularly against gastrointestinal cancers. They looked at data of trials which studied beta-carotene, vitamins A, C, and E and selenium. The authors concluded that “we could not find convincing evidence that antioxidant supplements prevent gastrointestinal cancers.”
One of the most recent developments in vitamin supplement research is the long-term SELECT (Selenium and Vitamin E Cancer Prevention Trial) study of the National Cancer Institute (NCI). The study evaluated the efficacy of selenium and Vitamin E in preventing prostate cancer and enrolled 35,000 male participants in the US, Puerto Rico, and Canada. The participants were randomly assigned to one of 3 groups: group 1 were given vitamin E supplements only, group 2 were given only selenium, group 3 took both supplements in combination, and group 4 were given placebos only. Five years into the study, the NCI decided to stop the trial because of some “concerning” findings, namely:
1. The analysis found no lower risk of prostate cancer in men taking the supplements, either alone or together.
2. Men who were taking only vitamin E actually had a slightly higher risk of developing prostate cancer.
3. Men taking only selenium seemed to have a slightly higher risk of developing diabetes.
Another study evaluated the efficacy of combined folic acid, vitamin B6, and vitamin B12 in reducing cancer risk among women. Their result show that combined folic acid, vitamin B6 and vitamin B12 treatment had no significant effect on overall risk of total invasive cancer or breast cancer among women during the folic acid fortification era.
A study published in December 2008 evaluated whether vitamins C and E and beta carotene supplementation have an effect on overall cancer risk. The data was taken from the Women’s Antioxidant Cardiovascular Study and involved 8,171 women who were cancer-free at the start of the study about 9.4 years ago. The findings of the study showed that “supplementation with vitamin C, vitamin E, or beta carotene offers no overall benefits in the primary prevention of total cancer incidence or cancer mortality.”
The Women’s Health Initiative Calcium/Vitamin D Trial evaluated the effects of vitamin D and calcium supplements on blood pressure and risk for hypertension risk of 36,252 healthy postmenopausal women. The women were assigned in 2 groups: one group received a daily supplement of 1000 mg of calcium plus 400 IU of vitamin D3 daily. The other group received placebo only. The researchers reported that “in postmenopausal women, calcium plus vitamin D3 supplementation did not reduce either blood pressure or the risk of developing hypertension over 7 years of follow-up.”
The Physicians’ Health Study II evaluated whether vitamin E or vitamin C have cardioprotective properties that can reduce risk for CVD in men. A total of 14,641 American doctors were enrolled in the study, aged 50 years and older, and were followed up for 8 years. The study results showed that “neither vitamin E nor vitamin C supplementation reduced the risk of major cardiovascular events. These data provide no support for the use of these supplements for the prevention of cardiovascular disease in middle-aged and older men.”
This study evaluated whether antioxidant (vitamins E, C and/or beta-carotene) supplements can prevent atherosclerosis. The researchers performed a meta-analysis of 22 trials which involved 134,590 participants. The researcher conclude that “…the majority of studies included in this review does not support a possible role of antioxidant supplementation in reducing the risk of cardiovascular disease … no definite conclusion can be drawn to justify the use of antioxidant vitamin supplements for the prevention of atherosclerotic events.”
Folic acid is routinely prescribed for pregnant women to prevent birth defects such as spina bifida. It has also been thought that folic acid, which reduced the levels of homocysteine in the blood, can prevent cardiovascular disease. Homocysteine is an amino acid used as biomarker for cardiovascular disorder. This trial investigated whether a vitamin combination pill with folic acid, vitamin B6, and vitamin B12 (vs. a placebo) can reduce cardiovascular risk. It enrolled more than 5,400 American women with a history of cardiovascular disease or with moderate to high risk profile for ccardiovascular disease. After 7.3 years of treatment and follow-up, a combination pill of folic acid, vitamin B6, and vitamin B12 did not reduce a combined end point of total cardiovascular events among high-risk women, despite significant homocysteine lowering.
While most of the evidence from studies summarized here does not seem to support the health benefits of vitamin supplements, there are some studies which indicate that vitamin D supplementation is worthwhile, even essential. Vitamin D is unique because we cannot get our vitamin D requirements from food alone. Instead, vitamin D is synthesized by the body upon exposure of the skin to the sun, thus earning it the title “sun vitamin.” However, since the sun is said to cause skin cancer, people tend to avoid exposure leading to widespread vitamin D deficiency.
American health experts are convinced of the necessity of vitamin D supplements and thus, routinely prescribe vitamin D supplements even for newborn babies. Milk and other dairy products in the US are fortified with vitamin D but not in many parts of the world. Last year, the American Academy of Pediatrics updated its guidelines for vitamin D supplementation to recommend the doubling of the dose for babies and children from 200 IU to 400 IU per day.
According to a review paper, “vitamin D is not only important for calcium metabolism and maintenance of bone health throughout life, but also plays an important role in reducing risk of many chronic diseases including type I diabetes, multiple sclerosis, rheumatoid arthritis, deadly cancers, heart disease and infectious diseases.”
In summary, antioxidants in fresh fruit and vegetables have been shown to have extensive health benefits. Unfortunately, except for vitamin D, the use of vitamin and mineral supplementation does not seem to reproduce the protective effect of natural food stuffs, as shown by many different studies summarized here. Worse, some studies even suggest that vitamin supplementation can actually increase risk for certain health conditions and mortalities. Most of the studies cited were long-term randomized, placebo-controlled trials involving thousands of participants. The data they presented are therefore, highly reliable.
The antioxidant supplement pill fits in quite nicely in this era of convenience food and lifestyle on the go. Unfortunately, it doesn’t look like a real healthy lifestyle and convenience can go hand in hand. The take home message is, when it comes to nutrition, there is no substitute for natural food stuff. Nature is still the best source of our nutritional needs.
