Name and Basic Overview

NOW Foods Certified Organic Spirulina is a dietary supplement that provides 3,000 mg of spirulina per serving, with each tablet containing 500 mg. Spirulina is a type of blue-green microalgae known for its rich nutrient profile.

It is naturally sourced from freshwater environments and is recognized for its high protein content and array of vitamins, minerals, and gamma-linolenic acid (GLA).

People commonly seek spirulina for its potential benefits in boosting energy, supporting immune function, and providing antioxidant protection.

Historical Background / Traditional Use

Spirulina has been consumed for centuries, with historical use by the Aztecs and other Mesoamerican cultures as a food source.

In modern times, it has gained popularity as a superfood due to its dense nutrient content and potential health benefits, which are now being explored in scientific research.

Composition and Active Components

The primary component of spirulina is protein, which constitutes a significant portion of its dry weight, making it an excellent source of plant-based protein.

It also contains essential vitamins such as B vitamins, minerals like iron and magnesium, and phytonutrients including beta-carotene and chlorophyll.

Gamma-linolenic acid (GLA), a type of omega-6 fatty acid, is another notable component, which may contribute to anti-inflammatory effects.

Research and Evidence Base

Numerous studies have investigated spirulina's health benefits. Clinical trials suggest it may support immune function, improve lipid profiles, and reduce oxidative stress due to its antioxidant properties.

A meta-analysis of spirulina supplementation has shown potential benefits in reducing cholesterol levels and improving blood glucose control, although more research is needed to confirm these effects.

While the evidence is promising, it is important to note that much of the research is preliminary, and further studies are required to establish definitive health claims.
