Happy with the quality and the size

I’ve really noticed an improvement in my digestion and associated skin issues since taking L-glutamine. After taking gel capsules for a few months I decided to switch to powder. This product is good quality and the powder is easy to take, so I plan to keep purchasing it.

My Go to!

This is a must have for my IBS as it help my intestinal lining to stay healthy. The taste is flavorless and dissolves easily in my coffee each morning. I have no complaints of the quality. This size container lasts me about 3 months or so as one little scoop a day does the trick.

Could not get lid off!!!

I have NEVER had an issue like this - neither me or my husband could remove the lid! It’s completely jammed and won’t budge. We are fit adults, so I can’t imagine anyone elderly or with weak grip strength having any chance of opening this. My husband was gripping so hard he dented the container. We may have to cut it open. As for the contents of this product, who knows yet!

If you need glutamate powder, this one's good

I was looking for glutamate powder and this brand was reasonable, and a good size for the price. I needed it as support to address gut health and amino acid deficiencies. This powder mixes easily into a almond or nut milk, and could be put into other food/drink or smoothies, so it's easy to take.

Good product

First time using glutamine, it's been a few weeks, but I can't really say if it helps with anything. However the ratio quantity/price is really good, just one ingredient and I like that it dissolves easily and is tasteless.
