Benefits of Spirulina

To date, few human studies have explored spirulina's health benefits. However, test-tube studies and animal-based research suggest that spirulina may help with the following conditions:

1) Allergies>

Spirulina holds some promise in the treatment of allergic rhinitis (nasal allergies), according to a research review published in 2009. Indeed, a previously published study of patients with allergic rhinitis found several benefits for spirulina consumption (including improvement in symptoms like nasal discharge, sneezing, congestion, and itching).

2) Diabetes

In a 2008 study involving 37 people with type 2 diabetes, researchers found that those assigned to 12 weeks of spirulina supplementation experienced a significant reduction in blood-fat levels. Spirulina benefits also included a decrease in inflammation and, for some patients, a decrease in blood pressure and cholesterol.

3) Oral Cancer

Spirulina may offer some protection against oral cancer, according to one small study of tobacco chewers with precancerous oral lesions. For 12 months, study members took either a daily dose of spirulina or a placebo. By the study's end, the lesions cleared up in 20 of the 44 participants who'd consumed spirulina (compared to three of the 43 participants who'd been assigned to the placebo group).

4) Weight Loss

Despite widespread marketing claims that spirulina can suppress appetite, there is insufficient evidence to show that spirulina can boost weight loss.

Side Effects

Although few adverse effects are associated with use of spirulina, consuming spirulina may cause headache, muscle pain, sweating, and insomnia in some cases.

Safety

As with all supplements, it's also important to consult your health-care provider before using spirulina in combination with other medications and/or supplements.
