Love this product, reasonably priced and great quality! I take 3g of it before bed and sleep like a baby! It’s the best thing when you are training lots and need to give your muscles a good rest. It also tastes sweet, so you can have it as sweetener in your evening cup of tea! The best!

Pure Glycine Powder - Great Value

This glycine powder from Metabolic Maintenance is pure and effective. The powder is unflavored and dissolves completely in water or juice without any grittiness. I take it before bed to support better sleep quality. The 7 oz container lasts a good while with daily use. The powder has no taste, making it easy to add to any beverage. Good quality supplement from a trusted brand at a reasonable price point.

Great!

I am using it as a sweetener for my tea before sleeping, but ofcourse its not the main reason why i am using it. It helps me to fall asleep better, improves my sleep quality and relaxes my nervous system. I ordered it to Cyprus. Delivery was not fast as i expected but that is not a problem.

Ye

I’ve tried glycine powder mainly in the evening, usually mixed into water before bed. It has a slightly sweet taste and dissolves easily, so it’s simple to take. The main thing I noticed is a bit of a calming effect that can help with winding down and sleep quality, but it’s not dramatic or instant every time. Overall, it feels like a gentle, useful supplement for relaxation and sleep support rather than something with strong, obvious effects.

Excellent quality but small quantity for the price

Metabolic Maintenance is an excellent brand with very high standards. However, the container is quite small considering the price. Since a therapeutic dose is 3g per night, this 200g size doesn't last very long. It’s a great, pure product, but I wish there was a larger, more economical option available.

Helps me sleep

This glycine powder taste good and helps me sleep. I was having issues with reoccurring thoughts while sleeping and read that a benefit of glycine is it helps with this. I have only been taking for a short time period but so far so good. I like the composition being powder and no additional ingredients.
