Source Naturals Glycine, for Protein Systhesis and Energy Generation*, 454 Grams - 16 oz Powder

It's decent quality--about the consistency of fine granulated white sugar. So...dissolvability/mixability is about what one would expect of sugar (not great and needing to be stirred a couple of times if not chugged in one go). It is, as all glycine products are, very sweet in a not- terribly- attractive way. Putting it in some product to consume is preferable to taking it straight. Initially I felt that it drastically improved the quality of my sleep, which is why I was taking it. I find it doesn't help now, and I suspect that is because I am no longer short of it in my system. Taking it in larger doses once appropriate levels of it are in the body seems to cause a sort of transient nausea/stomach upset, and so I am not currently taking it on a regular basis. If I find myself having more difficulty sleeping, I may try it again. What has helped me most with sleep is taking hormone replacement in the form of progesterone (but I am a post-menopausal female with extremely low levels of the adrenal and gonadal hormones), and I anticipate that the small testosterone dose I have begun recently will also contribute to improved sleep, according to human research efforts in the current healthcare literature.

This is a quality product. I love the sweet taste. The granules dissolve in liquid after a minute. This elicits a calmnes and helps me be ready for going to sleep. It's an easy way to give my body one of the components it needs to support healing and health in general.

I read a research study that showed that Glycine helps people to fall back asleep at night. I would have to get up 3 or more times a night and then often take 45 min to 2 hours to fall asleep again. This definitely works! My smart watch shows "excellent sleep latency" (the time it take to fall asleep) as opposed to before taking Glycine. Prior to taking Glycine, results would always show "poor" sleep latency. There is 1 gram of glycine in 1/4 teaspoon. I take 3 grams per night because that was dosage in the research study. I stir it into an 8 to 10 oz glass of water. It has a slightly sweet take, not unpleasant at all. It has changed my life. I was so tired all the time because of poor sleep. Also, Source Naturals is a brand that I trust.

The cheapest gylcine you can get. Works fine, tastes sweet, dissolves easily, has helped me with my nails and skin. I use it to help sleep and not have to urinate at night.

Good stuff. Helps with sleep and a bunch of other things in the body. Tastes a bit sweet so it's easy to take. 3-5g a day is all you need so this container goes a long way. I take it at night near bed time. High value supplement, recommended

I have struggled with insomnia for years, and tried dozens of ineffective remedies. I recently read an article about Glycine and NAC taken at night to help with sleep issues. It really does work. So grateful to have found this non-toxic, non addictive, nutrient-based option. It doesn't dissolve very well in cold liquids, and (for me) the flavor is cloyingly sweet. I mix it into a strongly flavored herbal tea an hour before bed.

Haven’t been taking it very long but I hope out hope that it does what it is supposed to to.

This supplement is great! I have been using is for a couple of weeks and have noticed seller sleep at night, more energy during the day. It dissolves easily in water or any drink. I does not have any smell or taste. Easy to use
