AFA is harvested from a stream-fed lake in Oregon. The quality of this bluegreen changes with the seasons and water conditions in Upper Klamath Lake. Because of the wild nature of AFA, BioFortify™ suggests that this bluegreen not be used by people under 18 years of age, pregnant women or lactating women. Also, the top daily intake of 2 grams per day should be reserved for people weighing 132 lbs (60 kg) or more. If AFA is a bit too wild for you, try Spirulina grown in a controlled environment.
Clean Chlorella is a nutrient dense aquatic botanical. Start with one or two tablets per day. Over time, daily intake can be increased slowly to 20 tablets per day. 4 grams per day can be obtained by taking 20 of the 200 mg tablets per day.
If you have never taken BlueGreen Algae (BGA) or Chlorella, then BioFortify™ suggests that you start with one or two capsules or tablets per day. After you are comfortable with small amounts of BGA or Chlorella, slowly increase to the suggested maximum of 2 grams per day for BGA and 4 grams per day of Chlorella.
