2. It can improve the appearance of skin, hair and nails
Studies done on gelatin supplements show positive results in improving the appearance of skin, hair, and nails. One study had women eat about 10 grams of pork or fish collagen (remember that collagen is the main component of gelatin). The women experienced a 28% increase in skin moisture after eight weeks of taking pig collagen, and a 12% increase in skin moisture after taking fish collagen.
In the second part of the same study, 106 women were asked to eat 10 grams of fish collagen or a placebo daily for 84 days. The study found that participants’ skin collagen density increased significantly in the group that took the fish collagen, compared to the group that took the placebo.
To stand out: Research shows that taking gelatin can also improve hair thickness and growth.
