Does taking more of a food supplement than the label states make it more effective?

Answer

No. The recommended daily amounts printed on food supplement labels are set by taking into account the safe intake limits established for different age groups and individuals. Exceeding that amount in the belief that the product will work better does not increase the effect; it can instead create a health risk, because upper limits considered safe for daily intake exist for the vitamins, minerals and other components these products contain. For this reason every approved food supplement carries on its label the recommended daily portion (for example 1 capsule, 2-3 tablets, 1 sachet, 1 scoop or 5 ml) together with the warning "Do not exceed the recommended daily portion." Food supplements should be consumed only in the stated amounts and in line with the instructions for use.
