Man-made vitamin D cholecalciferol is the active ingredient in rat poison. Check the Decon website. And it is not that hard to get enough vitamin D from the sun and from natural food sources. I like to supplement with Reishi mushroom and lions mane mushroom. And remember if you were chronically deficient in vitamin D it is a gut issue. #vitamind #vitamins ##supplements #foodismedicine #healthylife #naturalremedies #MTHFR #healyourselfnaturally | New Day Whole Health
