Certified Organic Spirulina Powder
Also known as: Spirulina, Blue-green algae, Arthrospira platensis
Overview
Spirulina is a type of cyanobacteria often found in freshwater lakes and ponds. It is noted for its rich nutritional profile, containing high levels of protein, vitamins, and minerals. As a dietary supplement, Spirulina is primarily utilized for its purported health benefits, including the enhancement of antioxidant defenses, and potential support in managing blood pressure and blood sugar levels. Spirulina contains phycocyanin, an active compound known for its anti-inflammatory properties. Research on Spirulina's health effects is moderately established, with evidence from systematic reviews highlighting various health benefits, although the quality of studies varies due to sample size and heterogeneity in results.
Benefits
Spirulina has several evidence-backed benefits: it significantly enhances antioxidant capacity, evident through increased total antioxidant capacity (TAC) and superoxide dismutase (SOD) activity. It may positively impact blood sugar levels, especially in type 2 diabetes patients, with evidence indicating a reduction of fasting blood sugar by approximately 17.88 mg/dL on average. Additionally, Spirulina seems to lower blood pressure, particularly in those with hypertension, while also potentially reducing total and LDL cholesterol. The anti-inflammatory properties of phycocyanin may provide therapeutic effects in conditions like ulcerative colitis. Benefits are observed within weeks of supplementation, with populations such as hypertensive individuals and type 2 diabetics experiencing the most advantages.
How it works
Spirulina's mechanism of action primarily involves its antioxidant activity, which enhances the body's defense mechanisms against oxidative stress by increasing TAC and SOD levels. The phycocyanin in Spirulina acts as an anti-inflammatory agent, which may contribute to reducing blood pressure and cholesterol levels in the cardiovascular system. Additionally, Spirulina plays a role in glycemic control, particularly in diabetes management by supporting endocrine function and insulin sensitivity.
Side effects
Overall, Spirulina is considered safe for most adults, though some users may experience gastrointestinal disturbances, including nausea and diarrhea (occurring in over 5% of users). Allergic reactions are rare (1-5% of users), and there is a potential low risk (<1%) of heavy metal contamination if Spirulina is not sourced properly. Caution is advised when taken alongside blood thinners or diabetes medications, and pregnant or breastfeeding women should avoid Spirulina due to insufficient safety data. Additionally, individuals with autoimmune disorders should consult healthcare providers before use, as Spirulina may affect immune system responses.
Dosage
The minimum effective dose for Spirulina typically begins at 1 gram per day, while optimal dosages range from 1 to 8 grams per day based on specific health conditions. There is no established maximum safe dose, though very high doses could enhance side effects. To minimize gastrointestinal issues, Spirulina is best taken with meals, and it is available in powder or capsule forms. Absorption may be improved when taken during meals, though specific bioavailability details remain limited.
