The Right Turmeric, For All the Right Reasons

Turmeric: A Common Spice, for Many Common Conditions

The “yellow curry powder,” turmeric, is one of the most valued spices dating back thousands of years for its food, medicinal, and even cosmetic uses. The most potent bioactive present in turmeric is curcumin, a pronutrient, i.e., it is converted into several active forms during metabolism when taken orally. Despite its broad nutritional benefits, concerns over poor solubility and poor bioavailability have risen over the years.

The Bioavailability of Curcumin in Turmeric

Intrigued by the potential health benefits of this "wonder spice," several strategies have been exploited to enhance curcumin’s bioavailability, namely solid lipid particle formulations, phospholipid complex, volatile oil complex, nanotechnology, and water dispersion technology, etc. Although some of the approaches have claimed the enhancement of bioavailability from 7 to 60 times higher than unmodified curcumin, the fact is these reports considered the sum of free curcumin and its conjugated metabolites (glucuronides and sulfates) while calculating the bioavailability. The free curcumin is capable of showing its biological activity and not the bound or conjugated forms. Therefore, this claimed "enhanced" bioavailability may not serve the concern of equivalently "enhanced" efficacy. It has to be noted that there would not be any inclusion of ingredients or bioavailability-enhancing agents detrimental to health, at the same time they need to be studied elaborately with adequate sample size while endeavoring to enhance the bioavailability of curcumin.

Studies revealed that curcumin will get converted into phase I and phase II metabolites within three hours after oral intake and it is the phase I metabolites (dihydro-, tetrahydro-, hexahydro- and octahydro-curcumin) that exhibit more potent biological activity than the phase II metabolites.

Challenges and Pitfalls Include:

  • Poor oral bioavailability
  • Rapid biotransformation
  • Formation of inactive metabolites
  • Equivocal efficacy of modified curcuminoids compared to placebo
  • Lack of substantially demonstrated "enhanced" benefits equivalent with the said "enhanced" blood circulation levels of modified formulations
  • Lack of extensive safety and toxicity studies for modified formulations
  • Possibility of the presence of toxic by-products

In light of all these debates, it is wise to choose unmodified curcumin. The raw material should be sourced from a known and qualified vendor, with a quality- and standards-complying partner, having an established entire supply-chain from farming to delivery, free from adulteration and substitution.
