Glycine 1000mg – A versatile amino acid in a practical format

Glycine 1000mg by EssentialSeries is a food supplement in vegetable capsules made from highly pure and concentrated glycine amino acid.

Glycine is an amino acid that the body can produce on its own, and it’s also found in protein-rich foods. However, more and more people are adding it to their diet as a food supplement because of its nutritional properties. In the body, it’s part of various structures including proteins and enzymes that play a role in metabolism.

Glycine 1000mg is the ideal food supplement to use as part of your nighttime stack, providing a high-purity amino acid in concentrated 1g capsules.

Your nighttime ally – In high-purity capsules

1000mg per capsule – High concentration

Most glycine capsule products on the market contain less than 1000mg, usually around 500mg. This is due to the natural size limitations of capsules and the amount of powder they can hold. The issue with lower-dose formats is that they require taking many capsules daily to reach an optimal dose.

A more practical and convenient way to supplement your diet with glycine.

Clean Label manufacturing – Vegetable capsules, allergen-free, no unnecessary additives

We developed our glycine capsules following the clean label philosophy, meaning we only use essential ingredients, with no unnecessary additives. By eliminating colourings and other aesthetic additives, we’ve created a transparent, high-quality product, staying true to our approach and values in supplement manufacturing: offering simple, practical, top-quality options.

Finally, our capsules are allergen-free, making them ideal for those who want to avoid ingredients like gluten or soy. Thanks to our clean room manufacturing process and cross-contamination-free ingredient supply chain, we guarantee the complete absence of allergens.

Glycine in your diet – Which foods contain it?

Glycine is a non-essential amino acid widely used as a food supplement. Even though the body can produce glycine and it can also be obtained from the diet, it’s common for daily intake levels to be relatively low. That’s why people often supplement their diet with this amino acid.

In food, glycine is mainly found in animal-based protein-rich foods like red meat, chicken, fish, and dairy products. Bone broths are also an excellent source of glycine, as they contain a high amount of collagen, which breaks down into glycine during digestion.

A key amino acid, in its most convenient form

At HSN you can also find pure glycine amino acid in powder form from our RawSeries brand.

Glycine powder is also very popular, as many people prefer it for the greater control it offers over dosage, and because glycine naturally has a sweet taste, which many people enjoy using as a mild sweetener. However, some people don’t like the sweet taste, so glycine in capsules is the ideal alternative, as this way the natural flavour of the amino acid isn’t noticeable.

Where to find Glycine and what to combine it with? 

You can find glycine in formulas already available in our range, mainly in powder form, as the ideal glycine dosage makes it difficult to combine with other compounds in capsule format without needing large quantities. You’ll find it in:

•  Sleep Care powder.
•  Deep Sleep Hot Chocolate.

Plus, it’s highly compatible with other products – as an amino acid, it’s safe to combine with all types of food supplements such as:

•  Melatonin.
•  L-Theanine.
•  EvoZMA.
•  Ashwagandha Extract.
•  Valerian Extract.
