I once queried the Price Pottenger foundation on what they thought activator
X to be (about 2 years back). I got no reply. Lots of candidates I suppose.
Could be an CLA http://www.lef.org/prod_hp/abstracts/php-ab153.html or an
omega 3. I suppose people in the past thought it was vitamin E or something
else. I always like to remind myself that there are many undiscovered
supernutrients and the only diet that has a hope of supplying them is the
Paleo diet.
