Gelatin may provide various health benefits.
Healthy body tissues
In its purest, powdered form, gelatin has a high protein content.
Protein is a macronutrient, meaning the body needs significant amounts to function.
Proteins are essential because they:
- build and maintain body tissues
- support the proper function of various organs
- act as enzymes and hormones

Skin care
Gelatin derives from collagen, which helps maintain the skin’s elasticity. With age, the body loses collagen. The skin becomes less firm, and wrinkles and lines may develop.
In 2021, researchers conducted a meta-analysis of studies looking at the impact of collagen supplementation on skin aging. The results suggested that taking hydrolyzed collagen for 90 days may reduce wrinkles by improving skin elasticity and hydration.
However, experts are uncertain that consuming gelatin would have the same effect.

Managing blood sugar
A small 2019 study indicated that glycine, an amino acid in gelatin, may help people with type 2 diabetes manage the condition by improving insulin sensitivity.
However, some gelatin-based foods, such as gummy candies, have high sugar content, so they are not suitable for people with type 2 diabetes.

Bone strength
Gelatin contains the amino acid lysine, which is important for muscle and bone health. It helps the body absorb calcium, keeping bones strong and reducing bone loss.
Studies have found an association between amino acid intake and increased bone density. For example, research from 2017 found that when rats with a magnesium deficiency consumed gelatin, it positively affected one aspect of bone density.
However, more research is necessary to confirm whether eating gelatin can improve bone health in humans.
Sleep quality
Gelatin contains high levels of the amino acid glycine. Some older studies suggest that glycine may improve sleep quality and other neurological functions. However, the researchers did not specifically recommend consuming gelatin to improve sleep.
Weight loss
Consuming gelatin-based products as part of a balanced diet may help promote weight loss due to gelatin’s high protein and low calorie contents. Protein helps people feel full, making them less likely to overeat.
However, some sources of gelatin, such as chewy candies and marshmallows, also have high sugar content. People should opt for low-sugar sources of gelatin, especially if weight loss is a goal.
