A recent study from Osaka University in Japan has revealed that adding vitamin D to the diets of fish increased their lifespan. This discovery could potentially apply to humans and other vertebrates as well.
The study focused on killifish, which have short lifespans ideal for studying aging. Researchers observed that removing germ cells had different effects on males and females, indicating potential longevity benefits for males through increased vitamin D signaling.
Dr. Holick, a researcher, emphasized the importance of the right dosage of vitamin D for optimal health and longevity. He highlighted previous studies showing the positive effects of vitamin D on lifespan and overall health, including cognitive function and reducing the risk of various diseases.
Interestingly, Dr. Holick pointed out that vitamin D produced by the skin through sunlight lasts longer in the body compared to oral intake. He recommended a balance of sensible sun exposure and vitamin D supplements for maximum benefits.
