10+ Foods High in Glycine (2023 UPDATE)

Glycine is an amino acid that plays a crucial role in many bodily functions, including the formation of collagen, a protein that gives structure to skin, bones, and other connective tissues. It also helps regulate the nervous system and aids in the production of glucose, which provides energy for the body's cells.

Many foods contain glycine, but some are particularly high in this essential amino acid. Here are a few examples:

1. Gelatin: Gelatin is a protein made from collagen and is one of the richest sources of glycine. It can be found in many processed foods like jellies, gummies, and marshmallows, but it's also a common ingredient in supplements and can be added to hot liquids to make a tasty and nutritious drink.

2. Meat and poultry: Meat and poultry, especially skin, bones, and connective tissue, are also good sources of glycine. Chicken skin, for example, is about 14% glycine by weight.

3. Fish: Fish, particularly the skin and bones, are also rich in glycine. Sardines and cod, for example, have about 5-6% glycine by weight.

4. Dairy products: Dairy products like cheese and yogurt are also relatively high in glycine, with some types containing as much as 3-4% glycine by weight.

5. Legumes: Legumes like soybeans, lentils, and chickpeas are good sources of glycine. Soybeans, for example, contain about 2-3% glycine by weight.

6. Vegetables: Some vegetable like spinach, kale, broccoli and other green leafy vegetables also contain a small amount of glycine.

It's important to note that while these foods are high in glycine, they may also contain other nutrients that are important for overall health. Eating a balanced diet that includes a variety of fruits, vegetables, and lean proteins can help ensure that you're getting all the nutrients you need.
