has a different value as the p572 NAG. Are they 2 different products?

No, it's the same product. All the usages listed are valid for N-acetyl Glucosamine, also known as NAG.

Heidi, In the Blood Type Encyclopedia, on page 488 at the bottom of the page on the left, it lists Co Enzyme Q10: 3 mg. Is that correct, or should it be 30 mg?

It should be 30 mg. Many CoQ10 supplements have even higher dosages, due to the low bioavailability of the CoQ10 in those specific preparations. There is a fairly new product called "Q-Gel," which claims to deliver more of the active compound per mg than other formulations do.

On page 103 of the Encyclopedia, Dr. D'Adamo recommends vitamin B6 (pyridoxine) in a dose of 20-30mg/kg for Type O's. For an 80kg man such as myself, that would equal up to 2400mg (2.4g) of vitamin B6 per day. The Merck Manual warns against such a high dosage -- can you confirm if this is correct? Ryan

That is an error: it should read, "2-3 mg/kg." We'll make sure the publisher is made aware of this correction -- thanks, Ryan!

One more for the Encyclopedia Errata - on p. 332 there is a recommendation to take 200 mg. of Melatonin. (YES, 200 mg.!) Take care! -- Judy

200 mg is the high end of dosage range for melatonin. Since the appropriate dose and the timing of it vary so much between individuals, you are squarely in front of your own drawing board if you decide to try it. Each increment starting at .1 mg (1 mcg) all the way up to 200 mg has proved ideal for at least one person. :-) I suspect this entry in the Encyclopedia could reasonably be changed to read "200 mcg," or .2 mg, which is a good starting point if you wish to experiment with this substance. Here’s an informative webpage on melatonin, with a detailed discussion of its functions in humans, and reliable guidelines for using it.

Thanks, everyone!

Hello there, eric ~~ I'm not familiar enough with the common store brands to be able to recommend any for you. :-( I prefer making my own salad dressing; it's quick & simple to make, cheaper than the bottled stuff, and I KNOW what's in it. So maybe these suggestions will help. :-)

If you have a blender, you are 3 minutes away from having your own personal salad dressing of any old kind you would like.

Here are a few Beneficial Blends for AB. Use them to get your imagination going on others you'd enjoy.

1) Basic: 1 cup olive oil, juice from one lemon, dash of sea salt.

2) Add to the basic recipe a handful of fresh basil or oregano - or 1/4 cup of red wine.

3) Fresh pink grapefruit, sectioned; 1 cup olive oil; one or two tablespoons of blackstrap molasses, touch of sea salt. Sounds bizarre, but it's very tasty!

4) 1 cup walnut oil, juice from 1/2 lemon, one tablespoon of miso, a raw garlic clove, two tablespoons brewer's yeast. Makes a rather thick, pungent dressing for Asian-style grilled vegetables, noodles, grilled turkey breast, or a hefty salad.

In all cases, just dump everything in the blender and whiz it up. Adjust to taste, and you're done!

I wouldn't think you will need to adapt the AB diet to handle the diabetes. In fact, it should begin altering you, since diabetes is one of the conditions it is designed to alleviate. People often write that after being on their diet for a few weeks, they needed to reduce their medication! so it's a good idea to keep a close eye on your insulin dosage, and stay in touch with your doctor.

Best wishes!
