Why we love it

High curcumin concentration for maximum benefits.

Vegan and allergen-free formula.
Main highlights

WHY BUY OUR HIGH STRENGTH CURCUMIN TURMERIC SUPPLEMENT TABLETS? Curcumin is the main beneficial active compound in turmeric. Most of our competitors provide turmeric powder capsules that only contain around 3% curcumin vs our 95% high strength extract. Each daily serving (2 tablets) has been formulated to provide the equivalent of 2000mg of the highest quality turmeric (35:1 Extract), 1000mg (23:1 Extract) of Ginger and 200mg (10:1 Extract) of black pepper (piperine).
VEGAN FRIENDLY, GLUTEN-FREE, DAIRY-FREE, CRUELTY-FREE, LOW CARBON FOOTPRINT - We understand the importance of providing immune system support supplements that are ethical as well as caters to everyone's needs.
SPACE SAVING & LETTER-BOX FRIENDLY PACKAGING - By providing our turmeric tablets in flat pack packaging, we save on costly postage and storage fees associated with bottled turmeric capsules. Savings are passed on to you and allows us to spend more on research, helping us provide our loyal customers quality products at great value prices, whether it's curcumin supplements, ashwaganda tablets, echinacea capsules or vitamins for immune system.
EASY TO SWALLOW WITH NO AFTERTASTE & DELIGHTFUL NATURAL AROMA - Our turmeric and black pepper tablets are 6mm in diameter and we believe are a better alternative to turmeric curcumin capsules - our customers think so too. Every time you take our turmeric tablets, you will be greeted by a burst of natural turmeric curcumin and ginger aroma - you won't be disappointed.
DO YOU ENJOY MAINTAINING AN ACTIVE LIFESTYLE OR NEED RELIEF? Our turmeric tablets high strength have been formulated to help aid you towards your health goals. We add black pepper as it plays a key role in increasing the absorption of curcumin and other curcuminoid nutrients found in turmeric.
