Metabolic Maintenance Glycine Sticks - 3 g Glycine - Calm & Sleep Support - Single Dose Powder Sticks - No Fillers or Preservatives - 30 Servings - 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 very different from the product I got before ARG bought the company. This version gives me nightmares, leaves the water cloudy instead of clean, and tastes different. I called the company, and they claimed that they have changed their sourcing, so it is not the same.

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?????

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

I have been dealing with insomnia for several years and have tried every non-medical treatment I could find. This is my refill order of Glycine because I wanted to give it a full try in combination with other natural treatments. And the answer FOR ME is Glycine in a cup of chamomile tea. I'm very happy with the results and hope this helps others with the same problem.

Well packaged, easy to use, pleasant taste.

I've been buying this for years and have been very happy with it. Recently, they merged with another company and changed the design. Now the sticks are impossible to open without a pair of scissors. Why pay extra for easy-to-use sticks when you have to grab a pair of scissors every morning?
