Difference and nutritional intake

Chlorella and Spirulina

Nutritional contribution

Chlorella, like Spirulina, are excellent sources of digestible protein and contain the nine essential amino acids that the body can not make and must be found in our diet.

Because they grow in freshwater pond, these two microalgae do not contain iodine and their sodium content is reduced.

Chlorella and Spirulina both contain essential elements for the good functioning of the organism.

In Chlorella, we notice an exceptional concentration of chlorophyll and lutein. Chlorella is the plant that contains the most chlorophyll and lutein on earth. (Lutein > 150mg/100g, Chlorophyll > 3,000mg/100g).

The Key Differences between Chlorella and Spirulina

Chlorella and Spirulina each provide polyunsaturated fatty acids in different and complementary proportions. Chlorella contains Omega 3 (like those found in flaxseed) while in Spirulina we find Omega 6.

Spirulina is rich in phycocyanin: a rare blue-green pigment immunostimulant and powerful antioxidant. Chlorella does not contain phycocyanin but contains chlorophyll, a powerful antioxidant also very active. Chlorella is very popular especially to detoxify the body and stimulate liver activity.

As the cell membrane of Chlorella contains not assimilable fibers (16 to 20%), Chlorella will be preferred by those who want to rebalance or stimulate their intestinal transit. Since Spirulina does not have a cellulosic membrane, it will be more easily digested than Chlorella and will be preferred by athletes; in addition, Spirulina can fight against muscle fatigue and restore energy and vitality.

Spirulina is richer in carotenoids, hence its essential protective effect to maintain good health and protects cells from the effects of aging. In recent studies carotenoids have also been identified as primary protectors for the cardiovascular system.

The absorption of iron contained in Chlorella and Spirulina is at least 5 times more effective than that from meat. 3 g of Chlorella or 5 g of spirulina provide between 4 and 5 mg of bio assimilable iron and correspond to about 50% of the recommended daily intake for over 50 years.1

Chlorella is preferred for its best iron supply.

Chlorella contains B12, 100% bio-assimilable and active compared to Spirulina which also contains partially assimilable B12 p.c. considered to be analog and therefore less active for humans.2

Chlorella

  • Stimulates the immune system
  • General well-being
  • Fight against constipation
  • Lowers the blood pressure and bad cholesterol
  • Suitable for vegetarians

Spirulina

  • Stimulates the immune system
  • Antioxidant and anti-aging effect
  • Lowers high-blood pressure and bad cholesterol
  • Improves muscle performance
  • Suitable for vegetarians

Moreover, Chinese researchers have shown that phycocyanin, a respiratory protein pigment unique to Spirulina, is involved in the bone marrow by stimulating the evolution and differentiation of stem cells of red and white blood lines.3

A sampling of slightly hypertensive volunteers consumed Chlorella for two months and noticed a reduction and a stabilization of their blood pressure as well as a reduction in LDL ("bad") cholesterol.4
