Doctors I know, anti-aging and endocrinologists, are typically more conservative than vitamin d counsel website. The problem is a lot of geriatrics are chronically low and infants generally do not get sufficient amounts that are breast fed. A lot of us eating decent amounts of tuna, salmon and etc. and with younger skin may be at optimal levels. Taking mega doses with optimal levels may lead to hypercalcemia. K may help plumbing and redirect calcium.
Where I diverge is in the belief that large doses of d will make a normal person feel any better or any different. It theoretically could have opposite impact if raises blood calcium. I think the d feel good may be a bit psychosomatic.
The feel good from the sun comes from An opioid B-endorphin via stimulation of POMC. Not sure d really produces any feel good reaction similar to the UV production of B-endorphin feel good response.
Thank you for the informative response. I agree with the more cautious approach insomuch as the average person just jumping on the D bandwagon with no baseline bloodwork or medical supervision at all. I do tend to believe the Vit D Council's stance that higher levels are generally indicated for most people when measured against the current RDA.
And I want B-endorphin in gel caps. Supp company reps get on this stat! lol
10,000 iu's per day of D3 + 2g ALCAR is excellent.
