There are numerous chemical compounds found in turmeric, with curcumin being the most important compound. It is the main active ingredient in turmeric and has powerful antioxidant and anti-inflammatory properties.

Curcumin makes turmeric a functional food; the food that has potentially positive health effects. However, the amount of curcumin found in turmeric is not that great. [1] Thus, it becomes extremely difficult to get sufficient curcumin intake by using turmeric as a spice in the meals. That’s why it’s highly recommended to take turmeric supplements that comprise of a substantial quantity of beneficial curcumin in it.

The Issue of Curcumin & Its Bioavailability

Curcumin tends to have antioxidant, anti-inflammatory, anticancer & neurotrophic activity, helping in preventing and treating several ailments. Although it works wonders on health, the poor bioavailability of curcumin becomes a major barrier to its clinical efficacy.

So, what is bioavailability and why it is so important?

Bioavailability (BA) is the rate at which the part of the substance is absorbed by the body’s circulatory system to have an active effect on it. This concludes that turmeric contained curcumin is very poorly absorbed in the body and the bioavailability of turmeric capsules needs to be improved. There are several reasons that contribute to the poor bioavailability of turmeric capsules. It includes:

  • Its swift metabolism and excretion from the body.
  • The way it is distributed throughout the body tissues.
  • Its short-life decreases its activity in the body.
  • Its low solubility in water.

Fortunately, there are numerous ways to improve the bioavailability of turmeric and turmeric capsules.

  • Combine turmeric with black pepper. Black pepper is rich in piperine, a natural substance which helps in boosting the curcumin absorption rate by 2000%. [4]
  • You can mix turmeric with fats such as olive oil, flaxseed oil or coconut oil.
  • The micronized powder and the liquid micellar formulation of Curcumin help in increasing its oral bioavailability. [5]

All in all, using any of the above methods can significantly increase the bioavailability of turmeric.
