Organic Spirulina Powder

Organic Spirulina Powder

1. Introduction

Organic Spirulina Powder, derived from Spirulina platensis (also known as Arthrospira platensis), is a nutrient-dense blue-green microalga widely used as a functional ingredient in dietary supplements, health foods and beverages. It is naturally rich in high-quality protein, essential amino acids, vitamins, minerals, carotenoids and the blue pigment phycocyanin.

Modern research indicates that spirulina supplementation can support antioxidant defenses, help maintain healthy blood lipids and blood pressure, and modulate immune responses when used alongside a balanced diet and healthy lifestyle.

Our Organic Spirulina Powder is manufactured in China from the dried thallus of Spirulina platensis and strictly controlled for microbial safety and heavy metals, making it suitable as a raw material for nutraceutical, food and cosmetic formulations.

2. What Is Organic Spirulina Powder?

• Botanical Source

Organic Spirulina Powder is produced from Spirulina platensis, a filamentous cyanobacterium cultivated in clean, controlled freshwater systems. It has a long history of use as a traditional food and, more recently, as a modern nutraceutical ingredient.

• Part Used

According to the Certificate of Analysis (COA), the thallus (the whole algal biomass) is harvested, dried and milled into a fine powder.

• Physical & Organoleptic Characteristics

Appearance: Dark blue-green powder

Odor: Characteristic

Taste: Characteristic

3. Key Health Benefits & Mechanisms of Action

1) Nutrient-Dense Superfood for Daily Support

Spirulina typically contains up to ~60–70% protein by dry weight, including all essential amino acids, along with B-group vitamins (including provitamin A as β-carotene), minerals (such as iron and magnesium), γ-linolenic acid, phycocyanin and carotenoids.

These nutrients make Organic Spirulina Powder a versatile base for:

General wellness supplements

Green superfood blends

Products targeting energy, vitality and recovery

Supported by research:

Comprehensive reviews describe spirulina as a high-protein, micronutrient-rich microalga used as a nutraceutical, and highlight its potential to support overall nutritional status when used as a food supplement.

2) Antioxidant Support & Oxidative Stress Balance

Spirulina contains potent antioxidant compounds such as phycocyanin, phycocyanobilin and carotenoids, which can help neutralize reactive oxygen species (ROS) and support endogenous antioxidant systems.

Mechanisms include:

Scavenging free radicals

Supporting the activity of endogenous antioxidant enzymes (e.g., superoxide dismutase, catalase)

Reducing lipid peroxidation markers in blood and tissues

Supported by research:

A 2016 review concluded that spirulina activates cellular antioxidant enzymes, inhibits lipid peroxidation and protects against oxidative stress in both preclinical and human studies.

A randomized, double-blind, placebo-controlled trial of a spirulina liquid extract (Spirulysat®) in adults with metabolic syndrome showed significant reductions in oxidized LDL/total LDL and isoprostanes, indicating improved oxidative status and a favorable impact on cardiometabolic risk markers.

3) Lipid Profile & Cardiometabolic Support 

Spirulina supplementation has been studied in multiple randomized controlled trials and meta-analyses for its effects on blood lipids and related cardiometabolic markers.

Key observed effects (across human RCTs and meta-analyses) include:

Reduction in total cholesterol (TC) and LDL-cholesterol (LDL-C)

Reduction in triglycerides (TG)

Modest increases in HDL-cholesterol (HDL-C)

Improvements in composite lipid profiles in subjects with dyslipidemia, obesity or metabolic syndrome

Supported by research:

A GRADE-assessed systematic review and dose-response meta-analysis of RCTs found that spirulina supplementation significantly reduced TC, LDL-C and TG and increased HDL-C, supporting its use as an adjunct to lifestyle measures for improving lipid profile.

A narrative review in Open Heart concluded that daily intakes of ~2–8 g spirulina can reduce body fat, waist circumference and BMI, while significantly improving blood lipid parameters.

A double-blind, randomized, crossover trial in overweight and obese men showed that Arthrospira (Spirulina) maxima supplementation combined with exercise significantly lowered total cholesterol, LDL-C and triglycerides compared with placebo.

In a Mexican population, spirulina supplementation in an open clinical study produced antihyperlipidemic effects, lowering TC and LDL-C while also showing antihypertensive trends.

4) Blood Pressure & Vascular Function Support

Beyond lipids, spirulina has also been investigated for its influence on blood pressure and vascular health.

Supported by research:

A meta-analysis of randomized controlled trials reported that spirulina supplementation significantly reduced both systolic and diastolic blood pressure, especially in individuals with elevated baseline blood pressure.

Clinical work with Spirulina maxima in overweight hypertensive subjects has shown improvements in blood pressure and endothelial function, suggesting a beneficial role in vascular health when used alongside standard care and lifestyle modification.

5) Immune Modulation & Allergy Support 

Spirulina is known for its immunomodulatory activity, including effects on cytokine balance and antibody production.

Supported by research:

In a randomized, double-blind, placebo-controlled trial in elderly Koreans (8 g/day spirulina for 16 weeks), supplementation significantly improved immune variables, including increased IL-2 and decreased IL-6, alongside favorable effects on total antioxidant status and lipid profiles.

A double-blind, placebo-controlled clinical trial on patients with allergic rhinitis found that spirulina significantly improved symptoms (nasal discharge, sneezing, congestion, itching) and reduced inflammatory markers compared with placebo, suggesting a beneficial immunomodulatory effect in allergy support.

Reviews summarizing clinical data note that spirulina can modulate cytokine expression and enhance innate and adaptive immune functions, supporting its positioning in immune-health formulations.
