Verified Buyer

“L glutamine and the other essential stacks products have been paramount to getting rid of four years worth of diarrhea with my special needs son.”

J Brimhall

Verified Buyer

“I have had some recent bloating and digestive issues lately due to the high dairy/meat diet of my fellow firefighters. Moved to a new station and almost every meal contained cheese. Dairy doesn't sit too well with me so I bought these as well as Essential Stacks Pure Glutamine. Within a few days I noticed a big difference with bloating and overall quality feeling of my poor intestines. Bought a second bottle.”

Donna Kilgore

Verified Buyer

“Down 30 lbs already, no more stomach pain, no more flare ups, no more bloat, no more feeling like everything I eat makes me sick, and finally truly REGULAR for the first time in my life -- without a handful of laxatives, stool softeners, and fiber supplements. I cannot THANK YOU enough for these products. ❤ Thank you thank you thank you!!!”
