Decomposed:
My initial thought after a cursory glance on the 'net' is Amazon. .06 a gram is CHEAP as dosage is suggested at 2 grams or 12 cents daily. Amazon is out of stock till 2/4 and I am not sure where the product is sourced from. On a side note some commenters have stated it has a sweet taste and that might be a plus for those persons, like myself, who no longer use sugars or artificial sweeteners.
Since I cannot "buy it now" I will most likely do a little more digging over the next few days and post my results here before I order.
The way I look at it, even thought I am only 53, a brain boosting supplement that can potentially help avoid such a terrible disease and help with better sleep etc. is a good investment and I figured many on this bored (sic) might also benefit.
Time, as always, will tell and we will see!
