Pure L-glutamine to support gut health, recovery, and immune function.
L-Glutamine is produced in the body and is the most abundant protein in the blood and other bodily fluids. However, highly active individuals usually have higher Glutamine needs than their bodies can produce. Therefore, supplementing with it is essential for those wanting to perform better.
L-Glutamine supports lean muscle mass, cell growth, and growth hormone release in the body, which is essential for improved performance. It also supports the immune system activity in the gut.

I was spending over $300/month on supplements from various brands. With Monthlees, I get the same quality — actually better, since everything is tested† — for less than half. My stack costs me $120 now.

I've tried every subscription box and DTC brand out there. Monthlees is different — it's like Costco for supplements. I'm saving 50%+ on my monthly† essentials without compromising on quality.

The transparency is what sold me. I can see exactly what's in each product, where it's sourced, and the testing results. Plus the savings are incredible.† My husband and I both use Monthlees now.

As a biohacker, I was skeptical because I'm used to paying an arm and a leg for supplements. But the quality is legit — these are premium formulas† at wholesale prices. The membership pays for itself in my first order every month.
