PhiNaturals Turmeric Curcumin Capsules: Curcuminoids are the main active ingredient in turmeric. Bioperine is a potent source of piperine – the bioactive compound in black pepper extract which works in powerful synergy with turmeric. You would have to eat a huge mound of turmeric to get the equivalent to one pill of Turmeric Curcumin with Bioperine. Because we concentrate the curcuminoids, each serving of 1400 mg is the equivalent of 4200 mg whole turmeric root. We're giving it to you in a form that your body can easily absorb and assimilate for the best and fastest results. Our supplement is a dose of 1500 mg.
