Product is great! Helps with recovery

Gritty like Chewing on Gravel

The L-Glutamine Powder that I had previously purchased was a fine powder that dissolved in my yogurt quickly, without any complications. The L-Glutamine product that I received earlier this month is gritty and doesn't dissolve at all. It is like eating sand or gravel in my yogurt. Please go back to the previous formula or processing method--the current product is unsuitable for consumption!

More than any other post workout supplement I feel I get a better recovery experience work L-Glutamine. It’s well packaged and easy to use.

Ordered to much

I love the product but I ordered too much. I won't use the entire bag for months.

Good texture, seems fresh

Dissolves well and adds a hint of sweetness to mixture. Appreciate the lack of fillers and hard gelatin. The integrity of the gut barrier is critical to healthy immune function. Glutamine is the main source of energy for the mucosal cells of the small intestine, and can help heal leaky gut.
