D-β-Tocotrienol is primarily used for its potent antioxidant properties, helping to protect cells from oxidative stress and free radical damage. It supports cardiovascular health by helping to maintain healthy cholesterol levels and reducing arterial plaque formation. This compound also shows promise in supporting brain health, with studies suggesting neuroprotective effects that may reduce the risk of neurodegenerative conditions. Due to its anti-inflammatory and cell-signaling modulation abilities, D-β-Tocotrienol is investigated for potential roles in cancer prevention, including inhibition of growth in certain cancers like breast and pancreatic, and as a supportive agent in metabolic health. It is commonly included in dietary supplements aimed at promoting longevity, heart function, and overall cellular wellness.

In the cosmetics industry, D-β-Tocotrienol is incorporated into skin care products such as moisturizers, sunscreens, and anti-aging creams due to its excellent skin penetration, ability to enhance hydration, reduce wrinkles, and protect against UV radiation.
