Pure Original Ingredients Glycine Powder (2lb) Non-GMO, Non-Essential Amino Acid, Allergen-Free

I am an experienced biohacking expert with over 17 years of experience and take a variety of supplements to improve my quality of life. Glycine is an amino acid that, according to many sources, can improve sleep quality, promote relaxation, regulate blood sugar levels, and improve overall metabolism, although scientific data on this issue is contradictory and the benefits of taking glycine vary from person to person. Nevertheless, I take 2 grams of glycine daily on a regular basis, although I cannot say that I feel any significant difference in my condition. However, it has definitely helped me and some of my patients subjectively improve sleep quality and reduce overall anxiety levels, although I do not rule out a possible placebo effect. I chose the powder form instead of capsules because it is generally more economical

High quality product at a great price. Bout this a couple times before and this one seems to be even better quality as it is of finer crystals, dissolves more readily and tastes better too when mixed in drinks. An ideal way to circumvent the glycine deficit that most human beings function on everyday.

Good quality

Amazing. Adding a pinch to morning coffee and able to concentrate better thru out day and sleeping better.

A first-time buyer of this product because of the favorable ratings, and have ordered Glycine from other vendors with high positive ratings as well . This batch has an extremely unfavorable odor as if washed in an ether or similar rinse. Asked for a refund and was initially denied called Amazon Prime and was refunded the full amount. Many other buyers had the same experience. Be wary of this even though others have had a majority of positive results with their shipments.

I'm taking glycine to address a potential nerve/autonomic issue related to equilibrium. I found the glycine caplets to be very effective, but this - despite taken in larger quantities - didn't really have any effect at all. I'm not sure why. Anyway, one thing it is good for is making pure Magnesium glycinate powder taste vaguely palatable. I take that at night, for a similar reason as the glycine, trying to improve sleep quality by chilling out a suspected overactive system. To no effect yet, I might add, but research is ongoing. Glycine is very sweet on the tongue. I've noticed no benefits from glycine otherwise, I don't feel better in any obvious way when taking it, so I don't recommend it as a prophylactic measure for any condition. It is, at best, inoffensive.

It is normal for glycine to be sweet. The name Glycine comes from the Greek word γλυκύς meaning "sweet tasting". This product is as sweet as any of the other Glycine products I have tasted and has been consistently cheaper over the past year. I use it along with inulin to sweeten things. I find also use a little to sweeten tea. (Note that most proteinogenic amino acids don't decompose until 185 degrees c or more. I seem to recall that Glycine doesn't until 240 C) Humans can synthesize Glycine from serine, so it is not considered an essential amino acid but there are studies that seem to show that older adults may benefit from glycine supplementation. Note that all of the bags I have received for the last year clearly state that 1/4 tsp is about 1.16 grams. I do pour contents from the bag into a glass jar for storage once I open it.

Excellent
