The World’s First Open-Source Supplement Company

Most companies use "proprietary blends" so they don't have to tell you the amount of each ingredient in their formulas. At Natural Stacks we believe it's your right to know exactly what you're putting into your body. We proudly publish our innovative formulas and ingredient suppliers in an open source format.

Excellent

We decided to try your products and not take others that we were taking. We wanted to make sure what was helping or not. My husband is scheduled for hip replacement surgery January 29th. Since taking the CBD, he is walking without his cane and the pain has subsided quite a lot. The only negative I have is when I take the sleep CBD, I wake up (after sleeping better) with a slight headache. I am blaming the melatonin- this has happened to me with other melatonin.By the way, my husband is 86 and I am 80.

My favorite stack ever

I've tried all of these ingredients on their own and never in a stack or continuously use together until this. I can say I have finally found a stack that matches what I need. Anger, irritability and anxious/depressive thoughts are gone. Never felt better! High quality products
