Glycine 3g Powder Sticks - 3000mg Amino Acid Supplement for Sleep, Calm & Energy Support, Pure Glycine Powder for Men & Women 50+, Travel-Friendly Packets - 30 Count

We have been using glycine sticks for a couple of years now, and these are the best we've tried. Taken before bedtime (open the sachet and tip directly in mouth), the glycine quickly helps us into a refreshing sleep. Other brands don't work as well, presumably because the quality of the glycine is not sufficient, and very few alternatives package like this - in 3g single shots. 3g is the optimum size according to scientific studies on the effects of glycine on sleep enhancement. Others add stevia, which is very bitter compared to glycine's natural sweetness. No thanks. I'll stick with metabolic maintenance. Update (Oct 2016): still going strong with the glycine sticks. With young kids, esp a 19-mth old infant, it's more important than ever to get to sleep quickly and deeply.

I like that these are high dose per packet. Nothing else added. Doesn't dissolve easily in liquid but easy enough to take straight into the mouth from the packet. Slightly sweet taste.

This is my second order and I feel like I am able to fall asleep much faster. I do have an issue though. I have probably used 4 of the packets with no problem. The packet I opened tonight had tiny black particles in it?????

Well packaged, easy to use, pleasant taste.

This product does not with my sleep. It is easy to take and with no taste.
