Blue Spirulina Algae Extract
Also known as: Blue Spirulina, Blue-Green Algae, Spirulina, *Arthrospira platensis*
Overview
Spirulina, scientifically known as *Arthrospira platensis*, is a type of cyanobacteria commonly referred to as blue-green algae. It thrives in freshwater lakes and ponds and is notable for its high nutritional profile, containing 60-70% protein, essential amino acids, vitamins, and minerals. Traditionally consumed as a dietary supplement, Spirulina is believed to offer various health benefits, particularly its antioxidant, anti-inflammatory, and immunomodulatory properties. The body of research investigating Spirulina is growing in maturity, with studies showing moderate evidence that supports its usage for enhancing health, although the quality of individual studies can vary widely.
Benefits
Spirulina may provide significant antioxidant effects, enhancing total antioxidant capacity (TAC) and superoxide dismutase (SOD) activity, although these effects are marginal. In terms of cholesterol management, it may lower total cholesterol (TC) and triglycerides (TG) while promoting high-density lipoprotein (HDL) cholesterol levels. Moreover, its anti-inflammatory and immunomodulatory properties could benefit individuals with conditions like allergic rhinitis. Athletes may also gain from Spirulina, as it has been shown to improve aerobic fitness and reduce muscle damage. Particularly, overweight and obese individuals may experience favorable changes in body composition. While many benefits may arise within weeks of supplementation, clinical significance varies.
How it works
Spirulina's health benefits stem from its bioactive compounds, especially phycocyanin, which play integral roles in antioxidant and anti-inflammatory pathways. These pathways can modulate oxidative stress and the inflammatory response, interacting with various body systems, including cardiovascular and immune systems. However, the specific molecular targets and detailed mechanisms remain inadequately defined, necessitating further extensive research.
Side effects
Spirulina is generally deemed safe when procured from reputable sources. Common side effects (occurring in over 5% of users) include gastrointestinal upset and potential allergic responses. Less frequently observed effects (1-5%) can involve skin rashes and elevated liver enzymes. Rarely, anaphylaxis may occur in susceptible individuals. Caution is advised if using blood thinners or diabetes medications due to possible interactions. Pregnant or breastfeeding women, as well as those with allergies, should consult a healthcare provider before using Spirulina. Overall, it's crucial for individuals in special populations or on concurrent medications to seek professional medical advice.
Dosage
The minimum effective dose of Spirulina generally starts at 1-2 grams per day. For optimal benefits, daily dosages typically range from 2 to 8 grams, depending on specific health goals. Although there isn't a well-established maximum safe dose, it is advisable not to exceed 10 grams per day. Spirulina can be taken at any time, ideally accompanied by meals for better absorption. Available in powder or tablet forms, the powdered variant can be conveniently mixed into foods or beverages. Additionally, bioavailability may be improved when consumed with vitamin C.
