why type O's are not recommended to use St Johns Wort. Aside from the fact that the two cases of "photo sensitization"
Type O's have lower levels of the enzyme MAO, and St. Johns
Wort is an MAO inhibitor feel "weird" or have disturbing dreams
type O's with mild to moderate depression do benefit from the
amino acid tyrosine (which can boost dopamine levels), and arginine (which is used to recycle nitrous oxide in the nervous system). Also, the gene for the enzyme dopamine beta hydroxylase sits right on top of the ABO gene and there are indications that this may cause psychiatric syndromes to be somewhat related to ABO blood group. Maybe those Japanese personality observations were not so off-the-wall after all?

stress. Many type A's with poor sleeping and stress tolerance are cortisol imbalanced. Why not try some St. John's Wort? It is a mild MAO inhibitor (probably) but actually more significantly, helps modulate cortisol metabolism through the p-450 enzyme system of the liver.

"The blood type O gene is very tightly linked to the gene for Dopamine Beta Hydroxylase" meaning that Os don't produce enough ornithine decarboxylase.  The shortage of this enzyme has digestive and emotional consequences, which results in Os having difficulty clearing some stress hormones and neurotransmitters out of their system. It does this by inhibiting the production of mono amine oxidase, which is responsible for clearing these things out (this being the reason why Os don't respond to MAO antidepressants)  It is also the reason Os are more prone to bipolar and unipolar depression.  We release enough neurotransmitters, but have no built-in ways of clearing them out.
Blood Type O has lower levels of the enzyme MAO, and St. John's wort is an MAO inhibitor. This may explain why many Type O's on St. John's wort say they feel "weird" or have disturbing dreams.  I have found, however, that blood Type O's with mild to moderate
depression benefit from the amino acid tyrosine, which can boost dopamine levels, or the Russian adaptogenic herb rhodiola, which
helps modulate adrenaline and dopamine levels in the brain.

cravings (under "stress and emotional stability"): "Many type Os crave either wheat or red meat. Wheat is one of the highest plant sources and red meat one of the highest animal sources of L-tyrosine, the building block of dopamine and the catecholamines." type O responds to stress with higher levels of catecholamines (adrenaline molecules) than the other blood types, and they do not clear them out of their bloodstream as fast. This is probably related to a gene linked to ABO that is involved in the regulation of dopamine metabolism, (the elective shunting of
tyrosine to dopamine or adrenaline or thyroxine). We also know that even normal healthy type O's have lower resting levels of platelet MAO (monoaminoxidase)which is known to produce a variety of personality manifestations including 'monotony avoidance.'

RESOURCE: Calculate Your Heart Rate Range

To calculate your desired heart rate during exercise, subtract your age from 220, then use 60 percent and 80 percent of that number as your fitness range. Here's an example, based on a 36-year-old:
SUBTRACT AGE      BOTTOM OF RANGE      TOP OF RANGE
220 - 36 = 184      184 x .6 = 110      184 x .8 = 147

This 36-year-old would aim for a heart rate between 110 and 147 beats per minute for a fitness workout.

There are all kinds of heart rate monitors on the market to help you measure your progress. But they are not the only method for determining your exercise intensity.

Catechol-O is formulated to optimize dopamine metabolism in type O's. It is not really a 'supplement' in the sense that it does some sort of semi-pharmacologic thing. What it does do is supply elements similar to the O diet in slightly higher amounts. I doubt one can become acclimated or addicted to it, since its actions are much like the diet itself.

Quoted Text

5HTP is probably OK in type O's...

Unfortunately, I've given up using it in my own practice as it didn't seem to work all that effectively, certainly not as effective as the older pre-problem L-tryptophane.

In general O's are better off boosting dopamine than they are boosting serotonin. try a little L-tyrosine instead.

Quoted Text

It is only my completely subjective opinion that many grain eating-vegetarian type O's are dopamine deficient, and perhaps
because of this some tend be more introverted, others more angry or agitated.

...  I am an Ao

Quoted from CB

   Running makes me feel great!!  I only run 5 to 6 miles/hr and also do weight bearing because it makes me feel great too.   Having said that I don't want to take years from life.   This is my quandry.    Where is Dr. D when I need him?    Take care.  CB

Quoted from italybound

okay, I'm always so confused about this blood typing thing.
Can one be Aa, Bb, or is it always Ao, Bo, Oo and AB. I know an A and a B or an O and a B can have an O baby, so this leads me to believe it is always Ao and Bo. Is that right?  

Quoted from Mayflowers

I used to run also, before my hips went.  I read that animals who have shorter lives than us,  have hearts that beat very fast. When you increase your heart rate you shorten your life. Wasn't man meant to sprint if I'm not correct? Only short distances of fast sprinting to run from predators?  The reason why you feel so great  is because when you run, your body is being stressed and the body compensates for that by releasing endorphins to take the pain away. So in actually, (especially in A's), you are being stressed more than if you swam or walked... by running instead. But I don't know if this applies to O's..

Do you think that there will ever be a blood test to find out if someone is AA or BB?

How do O's have a net increase in dopamine (the make-you-feel-good neurotransmitter) from exercise, even though increased MAO means decreased dopamine?

Quoted from Dr. D

Exercise blocks dopamine beta hydroxylase.
