I have been taking about 300-400 mcgs of B-12 on a full stomach for years and have good blood concentrations. My suggestion is take enough to get the blood concentration to about 1000 pcgs/mL.

I mention the spirulina because many vegans/vegetarians claim to get all they need from their normal vegan diet. Studies show some serious deficiencies in the vegetarian diet.
