You have a sachet of spirulina powder in your cupboard and you're not quite sure what to do with it? Consuming it as-is is technically possible but not very pleasant to the taste (pronounced algae flavor). The good news: there are 6 simple ways to incorporate it into your daily routine, from the quickest (lemon water) to the most creative (pesto, hummus). This article reviews the best pairings, appropriate dosages, and 3 signature recipes to transform spirulina into a daily ally without gustatory burden. For scientific benefits, see our article on 10 proven benefits.
Four practical guidelines. (1) Daily dosage : 1 to 3 g (1/3 to 1 teaspoon) per day for nutritional use. (2) Taste : pronounced and easy to mask with a sweet fruit (pineapple, banana), an acidic juice (lemon, orange), or an aromatic beverage (matcha). (3) Cooking : avoid above 60 °C to preserve phycocyanin. (4) Storage : opaque container, away from light and moisture, max 25 °C. For scientifically proven benefits, see our dedicated article.

Frequently Asked Questions
Can you drink spirulina powder in plain water?
Technically yes, but the algae taste comes through very strongly. Pair it with fruit juice, lemonade or a smoothie to mask the taste while preserving nutrients. If you prefer plain water, add a few drops of lemon and a touch of honey to soften the flavor. Drink quickly to avoid sediment.
How much spirulina powder per day?
Nutritional use: 1-3 g/day (1/3 to 1 level teaspoon). Targeted effect (lipids, blood pressure): 3-8 g/day for 8-12 weeks. Sports: 3-5 g/day. Start with 1 g in the first week to assess tolerance. Split into 2 doses if taking a higher amount.
Should you take spirulina in the morning or evening?
Rather in the morning or before 4 PM. B vitamins and energizing compounds may disrupt sleep in some sensitive individuals. Ideal at breakfast (smoothie, latte) or as an afternoon snack. For athletes, 30-60 minutes before training.
Does spirulina powder mix well with hot beverages?
Yes but with caution. Above 60°C, phycocyanin and certain vitamins may degrade. Favor lukewarm beverages (40-50°C) or add spirulina at the end of preparation after removing from heat. Lukewarm plant-based lattes are ideal.
How do you mask the taste of spirulina?
Four tips: (1) Very sweet and acidic fruit (pineapple, mango, berries). (2) Beverage with strong flavor (orange juice, lemonade, matcha). (3) Aromatic flavors (mint, ginger, honey). (4) Savory dishes with bold flavors (garlic pesto, spiced hummus, mustard vinaigrette). Avoid neutral flavors.
Spirulina powder or tablets: what's the difference?
Same nutrients, different formats. Powder : flexible, economical, ideal for recipes. Tablets : convenient, precise dosage, easy to transport. Start with tablets to assess tolerance, switch to powder for advanced uses (sports, high doses, recipes).
How long does spirulina powder keep?
6 to 12 months after opening under proper storage conditions. Sensitive to light, humidity, and heat. Store in original opaque packaging, tightly sealed, in a dry and cool place (max 25 °C). Khaki-green or brown color or unpleasant odor = discard.
Can you cook with spirulina (oven cooking)?
Possible but not recommended. Prolonged heat above 70 °C degrades phycocyanin. For savory recipes, add cold at the end of preparation. If cooking is necessary (pizza, soup, meatballs), accept partial nutrient loss. Spirulina will then mainly serve as a natural colorant.
Can children consume spirulina powder?
Yes from age 3, in appropriate doses. 3 to 12 years: 0.5 to 1 g per day (1/6 to 1/3 tsp). Mix into a sweet fruit smoothie to mask the taste. Check for algae allergies. For pregnancy and breastfeeding, apply precautionary principle: avoid unless advised by a doctor.
What are the best fruits to pair with spirulina?
Top 5: (1) Pineapple (sweet + acidic), (2) Banana (sweet, creamy), (3) Mango (very sweet, exotic), (4) Berries (fruity intensity), (5) Orange and lemon (acidity). Avoid neutral fruits (pear, white grape). Pairing 1 sweet + 1 acidic gives the best result.
