> Unfortunately, light boxes stimulate melatonin but don't take care of this Vit D problem. Do you know what dosages are in the megadose range? I'd sure like to start supplementing before waiting for an appointment, test results, etc.
The RDA has fairly recently been bumped up to 400 IU, but investigations based on the normalization of parathyroid/calcium levels show that the RDA should actually be near 1600. The megadose therapy for depression is a 100,000 IU bolus. Despite warnings about vitamin D toxicity, there has never been a single report of adverse reactions to this large dose.
