1. What is spirulina?

Spirulina is a blue-green algae (technically a cyanobacterium) that grows in alkaline lakes around the world. It is one of the most nutrient-dense foods on earth, containing 60–70% complete protein by dry weight, all essential amino acids, B vitamins, beta-carotene, iron, magnesium, gamma-linolenic acid (GLA) and a unique blue pigment called phycocyanin, which is a powerful anti-inflammatory and antioxidant.

Reference ranges and recommended intakes vary from country to country — always interpret guidance against the recommendations of your own healthcare authority.

2. Function and how it works

Spirulina supports fertility through:

1. Complete protein. Provides all essential amino acids needed for follicle, sperm and embryo development.
2. Iron and B vitamins. Bioavailable iron supports a healthy uterine lining; B vitamins support egg quality and methylation.
3. Antioxidant defence. Phycocyanin and beta-carotene neutralise reactive oxygen species that damage eggs and sperm.
4. Anti-inflammatory. GLA and phycocyanin reduce systemic inflammation, useful in PCOS and endometriosis.
5. Detoxification support. Spirulina assists the body in removing heavy metals and other environmental toxins.

3. Fertility benefits

Spirulina is particularly useful for:

1. Vegans and vegetarians needing additional protein and iron
2. Women with low iron or anaemia
3. Couples preparing for IVF or natural conception
4. Anyone undertaking a preconception detox
5. Women with PCOS or chronic inflammation

4. Recommended daily dose

I recommend a daily dose of 3–5 g of spirulina, taken in tablets or powder. Higher doses (up to 10 g per day) are well tolerated by most people. Spirulina has a strong taste — powder is best mixed into smoothies or juices to mask the flavour.

5. Sources

Spirulina is sold as:

1. Tablets
2. Powder
3. Capsules
4. Liquid extracts

Choose a reputable brand that batch-tests for heavy metals and microcystin (a toxin produced by some blue-green algae). Hawaiian and Indian sources are widely respected.

6. Cautions and contraindications

1. Avoid spirulina if you have phenylketonuria (PKU) — it contains phenylalanine.
2. Avoid if you have an autoimmune condition, as spirulina stimulates immune activity.
3. Stop if you experience digestive upset, headache or skin rash.
4. Always choose batch-tested products to avoid heavy metal or microcystin contamination.
5. Always consult with a fertility specialist or your doctor before starting any new supplement regime.
