On the basis of these findings and powerful marketing strategies, many healthy members of the population are now voluntarily consuming antioxidant supplements.
To produce effective food supplements as well as pharmaceutical formulations from these herbs, the responsible components for the antioxidant activity should be identified.
The combined evidence suggests that additional research on antioxidant supplements is needed.
It is advisable that the antioxidants are consumed from rich natural dietary sources rather than supplements.
It is suggested that indiscriminate use of antioxidant supplements should be avoided.
These results show the need to standardize dietary supplements in terms of their antioxidant capacity to match required doses to the oxidative status of consumers.

What are the health benefits of antioxidants?5 answersAntioxidants have a variety of health benefits. They can protect cells from free radicals, which contribute to heart disease, cancer, and other diseases. Antioxidants also have anti-aging and anti-inflammatory properties. They enhance the taste and safety of a wide range of foods. Antioxidants have been shown to protect cells from oxidative damage in both lab settings and observational studies. They can reduce lipid peroxidation, detoxify free radicals, activate endogenous antioxidant enzymes, and reduce levels of pro-inflammatory cytokines. Natural antioxidants from fruits, plants, and other sources have different health-promoting effects. Exogenous antioxidants obtained from foods can work together with endogenous antioxidants to maintain the redox reaction balance in the body. Consuming a diet rich in antioxidants, particularly fruits and vegetables, is linked to superior overall health effects. In addition to diet, adopting an active lifestyle with consistent exercise and stress management is important for good health.
What are the most effective and safe antioxidants for skin?5 answersThe most effective and safe antioxidants for skin include natural compounds such as naringenin, nordihydroguaiaretic acid (NDGA), kaempferol, polyphenols, tocopherols, carotenoids, ascorbic acid, and macromolecules (including polysaccharides and peptides). These antioxidants have been shown to attenuate free radicals' accumulation and provide protection against UV radiation-induced oxidative stress and skin damage. Encapsulation of these antioxidants into nanostructured lipid carriers (NLCs) can enhance their bioavailability and delivery to the skin. Additionally, the use of nanocarrier systems such as solid lipid nanoparticles (SLN), nanostructured lipid carriers (NLC), and nanoemulsions (NEs) can improve the stability, controlled release, and permeation of antioxidants in cosmetic formulations. Topical application of antioxidants, such as vitamins C and E, and selenium, can effectively protect against and reverse photodamage to the skin. These antioxidants, when applied topically, can reach higher levels in the skin compared to oral intake and provide long-lasting protection.
