‘Megadose’ Supplements: More Is NOT Better for Bone Health

In the 1990’s the dietary supplement industry went through a phase of megadosing.  Megadosing of antioxidants like Vitamin C, beta-carotene, and Vitamin E led to sweeping misperceptions among consumers about the supposed health benefits of taking large doses.

The vitamins most dangerous at megadose levels are the fat-soluble ones like Vitamin-A and Vitamin-E. It’s also possible to overdose on Vitamin-D supplements (not by diet or sun exposure), when vitamin D is taken at levels many times higher than the recommended dietary allowance.

Water-soluble vitamins like Vitamin C are safer, and the National Institutes of Health has set the tolerable safe upper intake level for Vitamin C at 2,000 mg/day in adults. While Vitamin C has low toxicity, too much Vitamin C can interfere with the body’s ability to absorb copper.  Megadoses of Vitamin C have been promoted as a treatment to various conditions including the common cold, cancer, and polio. High doses of Vitamin C may interfere with cancer chemotherapy. Large doses of Vitamin C have not been shown to cure the common cold or even prevent it in the general population.  In spite of this evidence, many people believe otherwise to this day, and marketers still capitalize on the myth. While modest vitamin supplementation has benefits, megadosing to fight disease is simply not supported by the available scientific evidence to date.

Although megadosing is rarely helpful with Vitamin C, on the other end of the spectrum, most people in the United States consume less than the recommended amount, 90 mg/day. This means that most Americans would benefit from modest supplementation with Vitamin C because it plays a protective role in building strong bones and preventing fractures. Vitamin C is essential for collagen production that is the framework for bone calcification - thus Vitamin C is one of the additional vitamins in Silical® 2 – part of Silical System.

In addition to Vitamin C, most Americans don’t get enough calcium and Vitamin D in their diets so some supplementation may reduce the risk of osteoporosis, but recent studies have shown that too much calcium increases the risk of heart attack and kidney stones. The point is that some supplementation can help most Americans reach the recommended daily amounts of vitamins and minerals, but megadoses can cause health problems. Very large doses of some vitamins and minerals may even have toxic effects.

A truly advanced approach to better bone health does not include megadoses in any shape or form. Silical® System* balances well-known nutrients with breakthrough nutrients in amounts that are consistent with NIH guidelines for recommended daily amount and safe levels. Silical integrates these new findings of safety and efficacy for calcium and vitamin D. Silical System is one of the only bone health supplements that includes organic silicon – plus extra nutrients that are important for bone health at recommended levels– and it's important to note that ALL of the nutrients in the Silical System are specifically chosen because they are insufficient in the average American diet.

Review your supplement plan with your doctor before taking large doses of vitamins,minerals, or other supplements.

*Adequate calcium and vitamin D, throughout life, as part of a well-balanced diet, may reduce the risk of osteoporosis.
