So, did the examine actually unlock learn how to sluggish growing older? Effectively, the 777-participant trial revealed {that a} mixture of two,000 IU of vitamin D and/or 1g of omega-3 a day alongside a easy, thrice-weekly 30-minute residence train program might sluggish organic growing older throughout 4 next-generation DNA methylation measures.
