Great product!
I used this supplement based on my nutritionist's recommendation to help lower my mercury levels. I took 5 capsules a day consistently until the packet was finished. My mercury level is now measuring twice as low as before.
It was easy to take: no aftertaste, no stomach discomfort. I took it first thing in the morning on an empty stomach with a full glass of water, and had absolutely no issues. Highly recommend if you're working on detoxing heavy metals!

Great product at a good price
The positive... It's chlorella at a good price. There isn't any flavor and the smell is not that bad, actually reminds me that I am taking algae. The health benefits outweigh any smell that it could have that people have been complaining about.
The only downside is that they are only 500mg tabs and wish for a 1000mg tab, but they are very easy to swallow and no taste to mention. Overall, you are getting a hefty amount for the price and they are a good quality compared to others that I have taken. I will be buying again when I start getting low especially for the fall and winter time to help the immune system.

Outstanding book
Format: Hardcover
Yes, Aristophanes was a genius in using satire to sting the then politicians. Oh! How we could we use his abilities today in the US!
I highly recommend this (and other similar) books to anyone who likes or loves to read excellent books with morals.
With this book I now have all of Aristophanes's plays to read over and over to my grandchildren, who love them. Thank you.
