The challenge with curcumin supplementation<br />

Despite the remarkable benefits of curcumin, the major challenge of supplementation is poor oral<br />

bioavailability. The major reasons contributing to low plasma and tissue levels of curcumin appear to be<br />

due to poor absorption, rapid metabolism and rapid systemic elimination. Earlier clinical trials investigating<br />

the benefits of curcumin required large doses of up to 12 grams per day in order to supply sufficient<br />

levels into the blood stream. The improvement of curcumin bioavailability has become a major focus of<br />

researchers with many enhanced curcumin extracts now available which claim to solve the challenge of<br />

poor absorption.<br />

Key points to consider when selecting a curcumin<br />

supplement<br />

Only bioactive or free curcumin is active within the human body and<br />

provides the benefits we want. Many companies measure not only<br />

free curcumin but include in-actives such as curcumin metabolites<br />

when measuring bioavailability. Ensure you understand the claimed<br />

improvement in bioactive or free curcumin bioavailability. It is<br />

easy to be misled by simply choosing a product with the highest<br />

supposed bioavailability. Ensure that you understand the difference<br />

between bioactive/free curcumin and curcumin metabolites to make<br />

an informed decision. This information should be transparent and<br />

available to you from a manufacturer.<br />

95%<br />

Standard curcumin 95% extracts offer a short active life of<br />

approximately 4-5 hours, resulting in users needing multiple doses per<br />

day. Ensure that you understand the active life of your supplement<br />

in order to compare and plan the required dosing schedule. Different<br />

products offer different active lives.<br />

Additional additives. In an attempt to improve bioavailability<br />

companies have combined curcumin with various substances, many<br />

of which may be questionable in a natural supplement or have<br />

potential consequences when used long term. Substances such as<br />

polysorbate 80 and Polyvinylpyrrolidone (PVP) are not uncommon.<br />

Piperine has also been used in curcumin supplements, however<br />

there is a concern related to their long term use, with various studies<br />

indicating potential risk. Piperine has been noted to be a potent<br />

inhibitor of drug metabolism and may be contraindicated for those<br />

using various medications.<br />

Clinical evidence. A body of reputable evidence exists which can be<br />

used to substantiate or validate claims being made about a product or<br />

its benefits.
