I am extremely happy with my products. The Bulletproof prebiotic powder is excellent as it is completely tasteless and great in coffee ☕️

Great service!

I have been ordering from OptimOZ for a year now. I have always been very happy with 1) the quality of the products and 2) the speed of the delivery.

At my last order, some of the products had a defect. The OptimOZ team was great in dealing with it. No questions asked, they sent me new products straight away.

I highly recommend!

I use it in my tea every morning.
