How to Use Spirulina

Spirulina is a health food supplement of blue-green algae. Found in the alkaline waters of Africa and Mexico, it is rich in B-complex vitamins, vitamin E, manganese, selenium and protein. Spirulina is also rich in chlorophyll, which may increase energy and act as a blood builder. Spirulina is considered a "superfood" because of its nutrient-dense content 2. It is usually available in a powdered form that you can add to food or drinks, although you may find it in tablet form. Always consult your doctor before taking a new supplement.

Take a 3,000mg dose of spirulina each day. Although a health-care provider will need to determine the right dose for you, 3,000mg is a standard dose for general health.

Add a dose of spirulina powder to smoothies, juices or yogurt to help conceal its slightly bitter taste.

Take spirulina at least one hour before drinking alcohol, coffee or soft drinks. These drinks may destroy the delicate nutrients and enzymes in spirulina.


Do not take spirulina if you have any seafood allergy, multiple sclerosis, lupus or rheumatoid arthritis. Spirulina may stimulate your immune system and make your condition worse.

Do not take spirulina if you have phenylketonuria, a rare condition that prevents the metabolism of the amino acid phenylalanine, which is abundant in spirulina.
