You are so right. I think the carrots did me in. Something shorted out the synapse and changed the well known D to an A.
I even went to the medicine chest to see for sure that the recently purchased new bottle was in fact Vitamin D and not A
I think that you can also get a good dose of vitamin D from sunshine. As long as you are not prone to skin cancer, if you garden in your swim trunks you will be healthy.
