A glycine supplement provides an amino acid that the body uses to make proteins, collagen, and other compounds. Glycine also has roles in the nervous system, but taking it has not been shown to treat disease or reliably improve every process it supports.
A glycine supplement may modestly support sleep for some people, but the evidence is limited. Small studies have examined taking it before bedtime; it is not a proven treatment for insomnia, and persistent sleep problems deserve attention to their underlying cause.
There is no established daily requirement for glycine supplements. Studies have tested different amounts, including 3 grams in some sleep research, but that is not a universal recommendation. Follow your product’s serving directions rather than increasing the amount on your own.
There is no required time of day to take a glycine supplement. If you are using it for sleep, research has generally examined taking it before bed; for other purposes, follow the product directions. Avoid taking it at a time that disrupts your usual routine.
A glycine supplement can cause digestive symptoms such as nausea or stomach discomfort in some people. If symptoms begin after you start taking it, stop and see whether they resolve; seek medical advice for severe or persistent symptoms.
Yes, a glycine supplement can generally be taken with creatine; there is no well-established harmful interaction between the two. They serve different roles, so combining them is not known to provide a special benefit beyond using each for its intended purpose.
Neither glycine powder nor capsules are inherently more effective if they provide the same amount. Powder can be mixed into a drink, while capsules avoid measuring and may be easier to carry; choose the format you can use consistently and correctly.
Yes, glycine supplements can be taken with collagen, but collagen already contains glycine. Combining them may simply increase your total glycine intake rather than provide a unique benefit, so consider what your collagen product already supplies.
Daily use has not been studied well enough to establish long-term safety for everyone. Short-term research does not prove that continuous use is risk-free; if you take regular medication or have a medical condition, ask a healthcare professional before making it routine.
A glycine supplement is not a proven way to lower or control blood sugar. Research on glycine and glucose metabolism does not establish it as a diabetes treatment, so do not use it in place of prescribed medication or glucose monitoring.

GLYCEMIC INDEX
GLYCEMIC LOAD
Accounts for portion size — a more realistic measure than GI alone.
To burn the 12 calories in 1 teaspoon (small) (3 g):

Swimming
Times are calculated with the MET equation for a 70 kg adult. Actual burn varies with your weight, age and pace.
A glycine supplement provides glycine on its own, an amino acid that serves as a building block of proteins. It is commonly sold as a fine powder or in capsules. The powder has a mildly sweet taste and can be stirred into water or another drink; capsules are usually taken with water. It is not a traditional food or everyday meal ingredient, though the powder can also be mixed into foods such as yoghurt.
Nutritionally, it supplies an amino acid rather than meaningful carbohydrate or fat. Check the product label for its serving guidance, and choose an unflavoured powder if you want to mix it into a drink without changing its flavour much.
Low
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
