Just got an upgrade(?) from Pharma grade glutamine to Ajinomoto as the pharma grade was on backorder. Don't know much about this brand/classification, frankly this is the first I've ever heard about it. I found this:
The Science Behind AjiPureÂ®
For more than a century, Ajinomoto Co., Inc. has pioneered the research and development of new and innovative technologies used to manufacture and purify pharmaceutical grade amino acids. AjiPureÂ® amino acids are fermented using only natural vegetable-based carbohydrates as raw materials. Ajinomoto Co., Inc. never uses raw materials of animal origin in any production process. AjiPureÂ® amino acids stem from over 100 years of clinical and scientific research, yielding unsurpassed quality and purity. Industry leading purification processes allow quicker absorption, faster bio-availability, proven consistency and unrivaled efficacy.* Ajinomoto Co., Inc. is the global leader in production, sales and research of amino acids used for medical, pharmaceutical, nutraceutical, sport, nutrition and health industries.
So it does indeed seem to be at the very least pharmaceutical grade. Anyone have anything else they can add?
My usual go to is Jarrow L-Glutamine as it is usually the crossroads were least expensive and highest quality meets.
