Sweet, works, until you don't need it
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.

Great product!
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.

Glycine changed my life!
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.

Will recommend for sleep
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 product
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

High value supplement
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

A relatively inexpensive way to source Glycine
I’m taking 5+ grams a day (GlyNAC protocol) and wanted to avoid a handful of capsules. I put half in my coffee and drink half in a glass of water. The granules do settle in the water, but I re-stir it.

Bought to Pair with My Collagen Powder
I picked this up to mix with my collagen powder as part of my daily routine. It blends easily and doesn’t have an overpowering taste or texture. I can’t speak to long-term effects yet, but it’s been easy to incorporate into my routine. Source Naturals is a highly trusted brand, so I felt comfortable choosing this one. Simple and straightforward.
