    I am taking 3 drops orally as a preventative for Alzheimer's.

I have no idea if this works. I am taking 3 drops orally as a preventative for Alzheimer's. It has been shown to aid in that, and this was a cheap source of it. I have had no ill effects other than a few stains on my counter when I spilled. I ad the drops to a glass of OJ and it doesn't impact the flavor much.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Try this for laughs

Should have ordered powder.  When powder is mixed with liquid soap, it makes for excellent tracking of most items when strategically placed with a cotton swab.A little bit goes a long way and can be a lot of fun.  Try making your friends urinate green on St Patricks Day or whenever - works very well in an open bottle of beer in a brown bottle.
