Age: 29 Height: 5 4 Weight: 120 Hi, I have a question about allergic reactions to taking Vit. D3. I just started taking 2,000 IU daily of a dry D3 vitmin from a company called Metabolic Maintenance, and noticed a difference in the way I feel - both good and bad. They make a dry formula - which is all I can take since I have multiple food allergies. I ve been on this supplement for 4 days and noticed on the third day that my tongue felt like it got burned (same feeling as when you drink something really hot and scorch your tongue.) AND I also felt nauseous right after taking the vitamin - no vomiting or anything like that, just nausea. Do you know if this is a common symptom of taking Vitamin D? Thank you so much.
