The Importance of Spirulina’s Cultivation Method and Environment

Spirulina, or Spirulina platensis, is a blue-green microalga that has existed on Earth for billions of years.

In 2000, the WHO recognized it as a “superior dietary supplement” due to its exceptional nutritional value. Spirulina’s properties are indeed impressive: it is rich in protein, minerals (especially iron and magnesium), essential fatty acids, amino acids, and antioxidants.

The iron content in spirulina is particularly noteworthy, as iron deficiency affects a significant portion of the population—especially women (30%).

Iron Absorption Mechanism and Bioavailability

Spirulina has unique physiological mechanisms that allow it to absorb and filter minerals—particularly metals—from its growing environment. As it grows, it naturally accumulates iron.

This is why it’s crucial to ensure that spirulina is cultivated in an environment free of heavy metals.

Once ingested by humans, spirulina gradually releases iron at optimal sites within the body, facilitating its absorption.

As a result, the iron naturally present in spirulina is highly bioavailable and easily assimilated by the body.

Not All Spirulina Is Created Equal

The quality and nutrient density of spirulina depend heavily on the growing conditions, geographical and climatic environment, and manufacturing processes.

Years of research were needed to develop Pharmalp’s spirulina, which is exceptionally rich in natural iron (1 tablet = 12 mg of iron, or 85% of the Nutrient Reference Value) and highly bioavailable.

The 12 mg of iron are present in two forms that are especially well absorbed by the body: free Fe²⁺ iron and iron bound to small proteins.

It is cultivated in a pristine natural environment (free from pollutants and heavy metals), and our tablet production follows GMP standards (Good Manufacturing Practices) to ensure both high efficacy and full safety for our customers.

A One-of-a-Kind Production Site

Our spirulina is cultivated in Ecuador at 2,500 meters altitude, benefiting from an ideal and stable photoperiod—12 hours of sunlight per day, every day of the year.

Our eco-responsible production is conducted without greenhouses or artificial heating, on a site that is Ecocert-certified.
