Aspalathin is primarily known for its potent antioxidant properties, making it valuable in the development of dietary supplements and functional foods aimed at reducing oxidative stress. It supports metabolic health by helping to regulate blood sugar levels, which is beneficial in managing type 2 diabetes. Research indicates it may improve insulin sensitivity and glucose uptake in cells. Due to its anti-inflammatory effects, aspalathin is also explored for use in skincare products, where it can help protect the skin from environmental damage and aging. Additionally, it contributes to cardiovascular health by supporting healthy lipid profiles and protecting against lipid peroxidation. Most commonly found in rooibos tea, it is increasingly used in nutraceuticals and natural health products for its wide-ranging health-promoting effects.
