"I love your algae!  The 500mg capsules are great!  I can see the crystals.  Why did the other algae we were taking not have the crystal appearance?  The other algae was also from Klamath Lake..."

... With your algae we get more for our money.  I started to increase my dosage...  I am so excited that we can actually increase our algae intake. Thank you for making such good quality algae at an affordable price...

... Thanks again for your time and wonderful support.  I have already passed your emails on to my two good friends who also eat algae.  You may be getting a few more orders! " Wendy N.
