The Effects of α-Linolenic Acid Intake on Skin and Blood Vessel Health and Subjective Fatigue in Middle-Aged Japanese Females: A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Comparative Trial

Even in the Japanese population, which has a mean consumption of high amounts of n-3 fatty acids, it is shown that ALA intake can increase the concentration of n-3 fatty acids in blood serum and contribute to maintaining the health of blood vessels. In addition, in people of normal weight, ALA increased skin hydration and contributed to maintaining skin health.
