Glucosamine is an amino sugar as well as the fundamental building block of the molecules responsible for attracting and holding water in cartilage. It has been found to work effectively in conjunction with chondroitin to help promote water retention in the cartilage, which is essential for your joints’ shock absorption. While glucosamine is most commonly found in joint health supplements, it has also been found to promote heart health.

A study in the United Kingdom observing 466,039 participants over a period of seven years concluded that self-reported daily glucosamine supplementation experienced a 15 percent lower risk of developing cardiovascular disease. In addition, participants saw a 22 percent decrease in risk of death, an 18 percent decrease in risk of congenital heart disease.

Gelatin is another common ingredient found in Flex Force joint support. Derived from connective tissues in animals, gelatin helps the body rebuild collagen, cartilage, and connective tissue in the joints. However, your joints are not the only parts of your body that benefit from gelatin’s collagen-producing properties.

Collagen is the protein responsible for providing structure and moisture to your hair, skin, and nails. Gelatin’s role in collagen production in the body may also be useful for improving hair thickness and growth along with retaining skin moisture.

Gelatin is also composed of glutamic acid, an amino acid the body converts to glutamine which strengthens the lining of the stomach and intestines and improves digestion. Gelatin is also 27 percent comprised of the amino acid glycine, which is known for improving sleep quality.
