I take about 250 mg of resveratrol every day (from Life Extension). I also take,
when I can find and afford it, pterostilbene, which is the methylated form of
resveratrol (and therefore not off-topic), which has important health benefits
of its own.

Swansons used to sell it at a reasonable price and then suddenly discontinued
it. I have found another site, but they charge a dollar a pill for a bottle of
60. This product also contains resveratrol.

The extract is called "pTerinol". It comes from the malabar kino tree.
I have ordered some from an ayurvedic website, but it's the raw herb. They use
it for diabetes, which I do not have.

I'm a big believer in both resveratrol and pterostilbene. Blueberries, by the
way, are the most common source of the latter in our diets, but they only
contain a trace amount.

Remember, pterostilbene is the methylated form of resveratrol. They go together
and mentioning it here should not be considered off-topic.

Does anyone know of a good source of pterostilbene capsules at a reasonable
price?
