Myth 8: "You can easily overdose on supplements."

Fact 8: True. As with most substances, it is the amount consumed that is the key. Almost anything is toxic if consumed in excess, including salt, alcohol and even water. Provided that supplements are taken in the amounts recommended on the pack by the manufacturer or retailer, and combining too many different supplements does not exceed the recommended doses, then it is highly unlikely that supplements will cause toxicity. The body to any great extent cannot store water-soluble vitamins - such as the B GROUP vitamins and vitamin C -, so if you take in more than your body needs, they are simply excreted. The fat-soluble vitamins A and D can accumulate in the body, but pose no danger to health if consumed within the safe upper limit indicated for them. The exception is in pregnancy, when large amounts of vitamin A may pose a risk to the developing infant. Pregnant women should seek advice from a doctor before taking a supplement containing vitamin A and people with blood clotting disorders should seek a doctor's advice before taking supplements containing vitamin E.

Finally, it is worth stating that quantities in excess of what we need or what is recommended may be harmful for a few individuals and that individual sensitivities and variations in response can occur, so if any unexpected symptoms appear whilst taking a particular supplement, medical advice should be sought.
