Revitalizing Aging Skin with Topical Vitamin C

Revitalizing Aging Skin with Topical Vitamin C - Life Extension:

While vitamin C is an important nutrient for overall health, little reaches the skin when orally ingested. As levels of vitamin C in the skin decline with age, replenishing levels directly in the skin can help combat collagen degradation and oxidative stress. Results from clinical trials show that when applied topically, vitamin C promotes collagen formation and mitigates the effects of free radicals, helping to maintain firm and youthful skin.

Blueberries Improve Insulin Sensitivity

Bioactives in Blueberries Improve Insulin Sensitivity in Obese, Insulin-Resistant Men and Women:

The mean change in insulin sensitivity improved more in the blueberry group (1.7 � 0.5 mg⋅kg FFM−1⋅min−1) than in the placebo group (0.4 � 0.4 mg⋅kg FFM−1⋅min−1) (P = 0.04). Insulin sensitivity was enhanced in the blueberry group at the end of the study without significant changes in adiposity, energy intake, and inflammatory biomarkers. In conclusion, daily dietary supplementation with bioactives from whole blueberries improved insulin sensitivity in obese, nondiabetic, and insulin-resistant participants.
