Chlorella — Green Algae for Detox & Health Support
Chlorella — Green Algae for Detox & Health Support
What is chlorella and what are its health benefits?
Chlorella is a single-celled freshwater algae considered one of the most nutrient-dense foods in the world. It is rich in chlorophyll, protein (60% of dry weight), iron, vitamin B12, and chlorella growth factor (CGF), which supports cellular repair. Chlorella is especially known for its detoxifying properties — it binds heavy metals and toxins in the digestive tract and helps remove them from the body.
Frequently asked questions about chlorella
Yes, chlorella is one of the few natural substances shown in studies to bind heavy metals (mercury, lead, cadmium) in the digestive tract. Chlorella does not remove metals from tissues but prevents their reabsorption from the intestine. For detox support, 3-6 g of chlorella powder or tablets per day is recommended.
Both are nutrient-dense algae with different strengths. Chlorella is a better detoxifier due to its chlorophyll content and cell wall structure. Spirulina contains more protein and beta-carotene and is better known for energy support. Many people take both together to get the benefits of each.
For general health, 2-3 g per day is recommended. During a detox course, the dose can be increased to 5-10 g. Start with a lower dose (1 g) and increase gradually, as chlorella may initially cause mild digestive issues. Chlorella is available in tablet, capsule, and powder forms.
Chlorella contains vitamin B12, but its bioavailability in humans is still debated. Some studies show that chlorella B12 can raise blood B12 levels in vegans, but most experts recommend vegans use a separate B12 supplement. Still, chlorella serves as a good complementary B12 source within a vegan diet.
