GlyNAC supplement combines glycine with N-acetylcysteine, usually shortened to NAC. The name refers to these two ingredients, which the body uses in making glutathione; it is not simply another name for NAC alone.
GlyNAC supplement provides two building blocks involved in the body's production of glutathione. Small human studies have explored changes in certain health measures, but the evidence does not show that GlyNAC prevents or treats disease.
GlyNAC supplement has not been proven to slow aging or extend lifespan. Research on glutathione and age-related measures is still developing, and changes in study measurements do not establish that the supplement reverses aging in people.
There is no universally established dose of GlyNAC supplement. Amounts used in research vary by study and product, so follow the serving directions on your product and do not assume that taking more will produce greater benefits.
GlyNAC supplement does not have to be taken on an empty stomach based on established evidence. Follow the product directions; taking it with food may be easier if it upsets your stomach, but there is no proven need to time it around meals.
GlyNAC supplement may cause digestive symptoms such as nausea or diarrhea, and NAC-containing products can also cause headache. Information on long-term use is limited, so avoid exceeding the serving directions on the product.
GlyNAC supplement may interact with some medicines, including nitroglycerin. If you take prescription medication or have a chronic condition, ask your doctor or pharmacist before using it because the risks can depend on your treatment.
There is no established timeline for GlyNAC supplement to produce a noticeable effect. Changes measured in research do not guarantee that you will feel a difference, or that any effect will appear after a particular number of days.
GlyNAC supplement contains both glycine and NAC, while a NAC-only product does not provide the added glycine. Taking the ingredients separately can provide the same two compounds, but the combination has not been proven superior to NAC alone.

A GlyNAC supplement combines glycine, an amino acid, with N-acetylcysteine (NAC). It is a supplement rather than a traditional dish, and products may come as powder or capsules, so the form and directions can vary.
There is no standard way to serve it at meals; people generally fit it into their daily routine according to the product label. Its nutritional character comes from amino acids rather than carbohydrate or fat, and a typical serving is about 5 g. If you choose to use it, follow the serving directions on the package; for powder, mix it only as instructed. It need not replace a balanced meal or the varied foods that provide protein.
Low
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
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.
