Been reading your articles on Vitamine D. Have a question, I understand best source is natural sun light, but can we also get it from grow lights or daylight bulbs?
Hi Art,
I have the same question and guess what, I find practical ways in getting it in Mercola's new book Dark Deception. I can't explain it all here but everything is there. I find it very insightful and I know you will too.
Cheers!
