Excellent product & helpful instructions
By Beverly B.
Since using these products, I have increased my energy, lost fat and increased my general health. It is a clear correlation and I wonder if the probiotics & Mg are the cause of the obvious physical changes. No matter. I feel and look great since taking these products for the past 60 days.

Excellent products sent Overseas super quick followed by a free hoodie due to spend amount. I also have realised that you get super low price on one of the products Post confirmation of purchase which reduces the average price of the purchase!!!!

Ive used supplements for most of my adult life. The biggest progress in my general health has been since I started using BiOptimizers cognibiotics, Masszymes, HCL and magnesium. I have suffered from food sensitivities for decades. One example is cashews. If I ate even a slither of cashew I would experience a severe headache within 10 minutes. Gladly I dont suffer from headaches other than from cashew exposure. But....I can now eat foods containing cashews and have no unpleasant response. I cant say 100% that it is these supplements but they are the only lifestyle factor I have changed.
