Spirulina, a type of blue-green algae, is a nutrient-dense superfood. Rich in various vitamins, minerals, and antioxidants, it is reputed for its immune-supporting and anti-inflammatory properties. Consuming spirulina can help combat oxidative stress and inflammation.
While generally safe, spirulina can occasionally cause minor side effects such as nausea and headache. Notable brands are Thorne, NOW Foods, Nutrex Hawaii, and Pure Hawaiian. Verify the supplement's purity to avoid contamination. Typically, a monthly supply of spirulina costs between $10 and $25.
