I know CHL and SPR are the great green combo...
But do I have to do them both? Why should I do them both?
In the short sum of things, no real reason to do them both. They really go hand in hand and do very similar things in the body. For the most part, Spirulina is a Blue/Green Algae, and Chlorella is a Green Algae. Both are known as micro-algae and are rich in Chlorophyll which has the therapeutic actions. Because Spirulina/Chlorella contain plentiful supplies of chlorophyll, they can be considered blood-building foods. Chlorella has more Chlorophyll than Spirulina and Spirulina has more protein. You would actually have to take more Spirulina to get the same effects of Chlorella, the ratio is 2:1 Spirulina:Chlorella.
Briefly I will list the properties of Chlorophyll:
Inhibits the growth of bacteria in aerobic yeasts and fungal infections, wounds, and in the digestive tract.
Deodorizes and sanitizes the body, is effective against bad breath and a toxic colon as well.
Can help to decrease tooth decay and gum disease when used orally.
Works as a natural anti-inflammatory in conditions such as arthritis, skin inflammations, sore throat, pancreatitis, gingivitis and stomach and intestinal irritation.
Builds the blood and nutritionally supports the body, especially if in a weakened condition.
Helps to stimulate the regeneration of tissue.
Promotes friendly intestinal flora which helps to ensure proper elimination and disease resistance.
Has the ability to enrich the blood and treat anemia. The molecular structure of chlorophyll is quite similar to hemoglobin (red blood cells).
Chlorophyll is sometimes called the "blood of plant life."
Specifically, Spirulina is the highest plant source of beta-carotene, vitamin B 12, and gamma linolenic acid (GLA). It contains more beta-carotene than carrot sources and 250% more vitamin B12 than liver. Spirulina is comprised of 65 to 70% of protein and provides all eight essential proteins. While beef is comprised of 18% protein, Spirulina is at least 65% protein. In addition, 80% of the protein content of Spirulina is assimilated by the body as compared to 20% for beef. The calcium content of Spirulina is 26 times that of milk.
There is so much more to this, but I tried to be very basic as to not overwhelm. You could very well do just one. Chlorella would be the less expensive option because you can take less and get the same results for the most part. Spirulina is not for everyone, so do additional research and make an informed decision. We know that persons with thyroid diseases may not be able to take Spirulina, it depends upon the individual, some can while others can't.
GREEN is GREAT, I am happy to be GREEN.
