I follow Dr. Davis's plan.

Just to give you a few examples on D3.

My wife takes 8000iu's daily and her 25(OH)D level is around 60ng/ml now. She has been taking this dose for over a year. She started at 10,000 and her levels came in at 97ng/ml so we backed off the dose from 10,000 to 8000iu's daily.

We live in the Northeast on Long Island and we are both in our late 60s. As you get older you lose the ability to generate D3 from the sun as well.

I take 10,000 iu's daily and maintain a level of 67ng/ml.

Both my wife and I are heavy. I am 260 and 6 foot tall and my wife is 5' 7" and around 210.

The level required of D3 is influenced by weight among other things. A thin person will need less as compared to a heavy person.

I also take 1200mg of magnesium daily.

What I did learn today and I had thought about was the B12. I missed that one completely. I take Metformin ER 1000mg in the AM and 1000mg in the PM.

My A1C is at 5.4-5.6 over the past three years.

So I think I will follow Hutchinson's advice and get the spray Methylcobalamin B12.

Never to old to learn.

Thanks,

Ralph
