Phytosterols are a group of naturally occurring compounds that are structurally similar to cholesterol, but are derived from plants. They are found in various plant-based foods such as nuts, seeds, and vegetable oils.
In protein powders, phytosterols are often added as a supplement to help reduce cholesterol levels and promote heart health. They work by competing with cholesterol for absorption in the small intestine, which can lead to lower levels of cholesterol in the bloodstream.
Phytosterols may also have potential benefits for athletes and those engaging in physical activity. Studies have shown that phytosterol supplementation may help improve endurance and reduce muscle damage and inflammation associated with exercise.
Phytosterols are generally considered safe when used in recommended amounts, and there have been no reported adverse effects associated with phytosterol supplementation.
