NOW Organic Spirulina 500 mg is a USDA Certified Organic, nutrient-dense blue-green microalgae tablet that supports energy metabolism, immune function, and antioxidant defense — delivering one of nature's most concentrated whole-food nutritional profiles in a clean, certified organic format.
Key Benefits of Spirulina
- Nutrient-Dense Whole-Food Support: Spirulina provides a naturally concentrated source of complete protein (60–70% by dry weight), B vitamins, iron, gamma-linolenic acid (GLA), and phytonutrients — supporting comprehensive nutritional status.
- Energy Metabolism Support: Spirulina's B vitamin content, including B1, B2, and B3, supports healthy cellular energy production and promotes sustained vitality throughout the day.
- Immune Function Support: Phycocyanin — spirulina's signature blue pigment — supports healthy immune cell activity and promotes a balanced immune response.
- Antioxidant Defense: Spirulina provides phycocyanin, beta-carotene, and tocopherols, which support cellular protection from oxidative stress and free radical activity.
- Cardiovascular Function Support: Spirulina's GLA content and phytonutrient profile support healthy lipid metabolism and promote normal cardiovascular function as part of a balanced diet.
- Detoxification Support: Spirulina's chlorophyll content supports the body's natural detoxification processes and promotes a healthy internal environment.
- Plant-Based Protein & Iron: Spirulina provides a bioavailable source of plant-based protein and non-heme iron, supporting muscle maintenance and healthy red blood cell production — particularly valuable for vegan and vegetarian diets.
- Alkalizing & pH Balance Support: As an alkaline whole food, spirulina supports healthy pH balance and promotes an optimal internal environment for cellular function.
USDA Certified Organic certification distinguishes this spirulina from conventional products by ensuring it is cultivated without synthetic pesticides, herbicides, or chemical fertilizers — a meaningful quality distinction for a microalgae product, as spirulina can readily absorb contaminants from its growing environment. NOW's Organic Spirulina is produced in controlled, certified organic cultivation facilities with rigorous heavy metal and microbial testing, providing an additional layer of safety assurance beyond organic certification alone. The compressed tablet format delivers a convenient, unflavored whole-food supplement that integrates seamlessly into daily wellness routines without the taste challenges associated with loose spirulina powder.

Frequently Asked Questions
What is Organic Spirulina 500 mg used for?
Organic Spirulina is used to support energy metabolism, immune function, antioxidant defense, plant-based protein and iron intake, and cardiovascular function — making it one of the most nutritionally comprehensive whole-food supplements available in certified organic form.
Why choose Organic Spirulina over conventional Spirulina?
Organic Spirulina is cultivated without synthetic pesticides, herbicides, or chemical fertilizers, and is subject to stricter contamination controls. Because spirulina readily absorbs compounds from its growing environment, organic certification and heavy metal testing are particularly important quality benchmarks for this ingredient.
How many tablets should I take per day?
The recommended serving is typically 3–6 tablets per day with meals or as directed by a licensed healthcare provider. Follow current label directions for specific dosing guidance.
Does Spirulina have a strong taste or smell?
Spirulina has a naturally earthy, algae-like flavor that some individuals find strong in powder form. The tablet format minimizes direct taste exposure, making it a more palatable option for those sensitive to spirulina's characteristic aroma and flavor.
Is Spirulina safe for daily use?
Organic Spirulina is generally well-tolerated for daily use as a whole-food supplement. Individuals who are pregnant, nursing, immunocompromised, or taking prescription medications should consult a licensed healthcare provider before use. Those with phenylketonuria (PKU) should note that spirulina contains phenylalanine.
Can Spirulina support iron levels in vegans and vegetarians?
Yes — spirulina provides non-heme iron alongside vitamin B12 precursors and protein, making it a valuable nutritional supplement for individuals following plant-based diets who may have limited dietary iron sources. Note that non-heme iron absorption is enhanced by consuming vitamin C alongside spirulina.
Yes — NOW Organic Spirulina undergoes testing for heavy metals including lead, mercury, arsenic, and cadmium, in addition to standard GMP quality testing for identity, potency, and microbial purity.
Is this product third-party tested?
Yes — NOW Foods products are manufactured in GMP-certified facilities and undergo rigorous in-house and third-party testing for identity, potency, purity, and heavy metal content.
