Spirulina contains substances called polysaccharides, which help your digestive organs release energy. This effect raises the levels of healthy lactobacillus in your digestive tract, which enables the production of natural vitamin B6. It’s well-known that the B-vitamins facilitate energy release from food, which means that spirulina seems to help you feel more energetic in a variety of different ways.
Allergy and Immune Benefits
Spirulina essentially works as a natural antihistamine without all the side effects. While there’s a lot we still don’t know about how spirulina interacts with the human immune system, research suggests that this substance has at least some anti-allergy effects to support conditions such as hayfever.
This natural substance fights allergies by preventing the release of histamine, which is a pro-inflammatory substance that causes allergic reactions. Scientists don’t know exactly how allergies work, so it can’t be said that spirulina is a cure for rhinitis, hay fever, and other related conditions. However, it’s a straight fact that any substance that exerts antihistamine action will reduce allergic symptoms.
Cardiovascular & Diabetes Benefits
A 1998 study indicates that spirulina lowers bad cholesterol, which in turn is associated with a possible reduction in risk of other cardiovascular conditions. The researchers “gave 4.2 g day−1 of Spirulina to 15 male volunteers and, although there was no significant increase in high-density lipoprotein (HDL) levels, they observed a significant reduction of high-density lipoprotein (LDL) cholesterol after 8 weeks of treatment.”
A small study of diabetes patients in India sought to establish the potential benefits that sufferers of this condition might gain from spirulina supplementation. This study found that spirulina reduces triglycerides and lowers blood glucose levels in addition to reducing unhealthy cholesterol.
Anti-inflammatory and Antioxidant Benefits
While clinical research into the anti-inflammatory and antioxidant benefits of spirulina is limited, detailed analysis of the spirulina cyanobacteria has detected the presence of a variety of different proteins and other substances that have the ability to scavenge free radicals and prevent inflammation in other ways.
It appears that spirulina exerts the majority of its benefits via its ability to modulate inflammation and other immune functions while simultaneously reducing oxidative stress throughout the body by scavenging free radicals. While reducing oxidative stress usually reduces inflammation as well, substances that achieve both effects at the same time are rarer, which truly makes spirulina a superfood of the future.
