Spirulina & Chlorella: powerful microalgae for wellness – what does the science say?

In a world increasingly focused on natural well-being, spirulina and chlorella are gaining recognition as true plant-based superfoods. But what does science really say about them?

🌿 What are they?

Spirulina (Arthrospira platensis) and chlorella (Chlorella vulgaris) are freshwater microalgae packed with nutrients. Rich in protein, chlorophyll, antioxidants, vitamins, minerals, and essential fatty acids, they have been studied for decades for their health-promoting potential.

✅ Proven benefits

💚 1. Cardiovascular support

Multiple clinical studies have shown that regular intake of spirulina or chlorella can:

• lower LDL cholesterol and triglycerides

• improve blood pressure

• support vascular elasticity

🍬 2. Blood sugar regulation

Research on type 2 diabetic patients shows both microalgae may:

• reduce fasting glucose levels

• lower HbA1c (glycated hemoglobin)

🛡️ 3. Immune system support

Thanks to their antioxidant content and bioactive compounds, spirulina and chlorella can:

• enhance immune cell activity (e.g., NK cells, macrophages)

• increase antibody production

💪 4. Physical performance & recovery

Spirulina is especially valued by athletes for its ability to:

• boost endurance
