What is the acceptable daily intake of curcumin?
All products in contact with humans must undergo toxicity tests to determine safe doses and thus avoid side effects. For curcumin, foods and supplements should provide no more than 153 mg of curcumin per day. A rate that is difficult to achieve even when taking a lot of turmeric and traditional supplements. But improving bioavailability rearranges the cards. Without exceeding the ADA in absolute terms, these formulas can exceed it issue of bioavailability.
