Is it true that people with blood A type absorb Vitamin B less efficiently and requires higher dosages?

Question

Just for info, i got this info from this link:

http://ezinearticles.com/?Hair-Loss:-Biotin-is-Food-for-Your-Hair&id=126771

(This is the sentance: Additionally, those with type A blood don't have the ability to fully absorb B vitamins. Biotin is classified as a Vitamin B, so if you have Type A blood, adding higher doses of 5-8 grams twice daily will be needed... )

Answer 1

No, we don't.

Answer 2

Don't believe everything you read on the internet.  Where exactly did the woman who wrote that article get her MD or PhD?  What proof does she give of her assertion?  She's selling hair products.

She also says elsewhere in the article that you would have to eat "thousands of calories a day" to get the levels she's recommending for your "hair needs," so I guess through all the thousands of years before biotin supplements, people's hair all fell out automatically?  It's a silly claim.

Answer 3

Could you give your source for that?

Is it also the case that people with blood type B absorb Vitamin A less efficiently? just kidding.
