Re: New Research Challenges Concept of Vitamin D Deficiency Doesn't it say "ingested"? >.............> Marshall's research has demonstrated how ingested vitamin D can actually block VDR activation, the opposite effect to that of Sunshine. Tanning beds should have the same effect as natural sunshine. One of my customers is taking classes in naturapathic healing (hope my spelling is close). She also has psorasis (as I do). She said that tanning beds and natural sunlight are the best ways to get your Vitamin D. You can overdose on Vit D supplements. They can cause kidney failure. Isn't there a law suit in progress, because of Vitamin D supplements and pet food? |
