What Makes Essential Stacks Different

What Makes Us Different

Most supplement companies cut corners where you can't see - using overseas manufacturing, skipping independent testing and loading products with gut-irritating fillers. We take the harder, more expensive path because your gut health deserves better than “industry-standard”.

What make us different
Essential Stacks Powder Products

Mixes well in any beverage.
Dissolves instantly.
No grit or taste.

Third-Party Tested
In The USA

Most companies only test their products internally - we do both. Our formulas get tested in-house, then verified again by independent ISO-certified labs where scientists screen for contaminants and validate our allergen-free promises. Because we believe your gut health journey deserves nothing less than exceptional quality.

Affordable Alternative To Pricier Brand

I was looking for a more affordable alternative to the L-Glutamine supplement I'd been taking. I stumbled across Essential Stacks when researching and I'm glad I did. Its supplement is easy to blend into by daily drinks and has no noticeable taste.
