Spirulina: better powder or tablets?

Spirulina’s flavor is partly reminiscent of chlorophyll and partly of the sea. Compared to other algae, it’s less intense, since it’s actually a freshwater organism. Technically, it isn’t even an algae: spirulina is a cyanobacterium; a spiral-shaped microorganism that has existed since the dawn of Earth.

What is spirulina?

Spirulina, or Arthrospira platensis, belongs to the class Cyanobacteria.
It has a dark green color due to chlorophyll and striking blue reflections from phycocyanin, its star antioxidant pigment.

Spirulina thrives in alkaline lakes and streams and is so resistant that NASA chose it for long-duration space missions. Both the WHO and the UN have praised it as one of the most promising foods for the future.

Why take spirulina?

Spirulina is considered a superfood because of its dense nutritional profile:

• Protein-rich (about 60–70% of its weight) – excellent for vegetarians, vegans, and athletes.

• Minerals & vitamins – including iron, magnesium, potassium, B vitamins.

• Antioxidant & anti-inflammatory properties – mainly thanks to phycocyanin.

• Energizing and restorative – often used to support endurance and recovery.

Spirulina powder vs tablets: what’s the difference?

The nutritional value is identical: both are made from dried spirulina processed at low temperatures to preserve nutrients. The only difference is form and convenience:

• Powder → ideal for mixing into food and drinks. Best for those who enjoy experimenting with recipes.

• Tablets/capsules → best for those who dislike spirulina’s taste or want an easy supplement-on-the-go.

Tip: if you’re just starting, tablets might be easier. If you love experimenting in the kitchen, powder gives you endless possibilities.

How to choose Spirulina

When buying spirulina, always check:

• Cold drying process → Spirulina that has been processed at low temperatures preserves proteins, antioxidants, and phycocyanin. NaturaleBio uses this method to keep the nutritional profile intact.

• Organic certification → This guarantees cultivation without pesticides, chemical fertilizers, or contaminants such as heavy metals. NaturaleBio Spirulina is 100% organic certified, ensuring purity and safety.

• Transparency of origin → The best spirulina comes from controlled freshwater environments with strict monitoring. NaturaleBio works only with carefully selected farms and performs lab tests in Europe for every batch.

By focusing on these aspects, you can be confident you’re choosing spirulina that’s both safe and nutritionally superior.

How to take Spirulina

• Daily dosage: 2–3 g (about 1 tsp powder or 3–6 tablets).

• Start small: begin with half the dose to let your body adjust.

Powder

Use it like a “super-spice” in both sweet and savory recipes:

• Sprinkle on roasted veggies, salads, or potatoes.

• Mix into smoothies, juices, or plant-based milk.

• Add to yogurt, oatmeal, or energy balls.

• Experiment with green doughs for pasta, bread, or gnocchi.

Tablets

Simply take them with water, preferably with meals for better absorption.

• Start with small doses to avoid bloating or mild digestive discomfort.

• Avoid if pregnant, breastfeeding, or if you have thyroid issues, autoimmune diseases, or phenylketonuria.
