Where is your L-Glutamine made?

Our L-Glutamine tablets are manufactured in the USA.

On the other hand, our powdered L-Glutamine is imported from an advanced facility in Japan, then refined, checked and bottled in the US.

We use a UV spectrometer to check for any unwanted ingredients, which includes things like heavy metals. We can’t speak for other products from overseas, but ours is as pure as you can get.
