Spirulina Benefits
By Dr (TCM) Attilio D'Alberto | Traditional Chinese Medicine Practitioner, Wokingham
Spirulina is a blue-green microalgae that has been used as a food source for centuries and is now one of the most researched nutritional supplements in the world. It is exceptional in its nutrient density — gram for gram, it contains more protein than meat, alongside a wide spectrum of vitamins, minerals, and phytonutrients. In the context of traditional Chinese medicine, spirulina is valued for its ability to build blood and yin, making it particularly relevant for women with hormonal imbalance, fertility concerns, or chronic fatigue.
Nutritional Profile
Spirulina is approximately 60–70% protein by dry weight and contains all essential amino acids. It is one of the few plant-based sources of complete protein. It is also rich in iron, B vitamins (including B12 in a limited but bioavailable form), gamma-linolenic acid (GLA), beta-carotene, and the potent antioxidant phycocyanin — the pigment that gives it its distinctive blue-green colour. Its iron content is particularly relevant for women with heavy periods or prolonged menstrual bleeding who are at risk of iron deficiency.
Antioxidant and Anti-inflammatory Effects
Phycocyanin — spirulina's principal active compound — is a powerful antioxidant and anti-inflammatory agent. Research has demonstrated its ability to inhibit lipid peroxidation, neutralise reactive oxygen species, and reduce pro-inflammatory cytokines including TNF-alpha and IL-6. These effects are clinically relevant for conditions driven by oxidative stress, including poor egg quality, sperm DNA fragmentation, and inflammatory conditions such as endometriosis.
Immune Modulation
Spirulina is an immune modulator — it enhances natural killer cell activity, stimulates macrophage function, and promotes IgA production in mucosal tissues. Clinical trials have shown benefits for allergic rhinitis, with significant reductions in symptoms including nasal discharge, congestion, and sneezing. For patients with allergies or recurrent infections, it is a useful addition to a broader nutritional and herbal protocol.
Blood Sugar and Cholesterol
Several clinical trials have demonstrated that spirulina supplementation reduces fasting blood glucose, HbA1c, total cholesterol, and LDL cholesterol while raising HDL cholesterol. These effects are relevant for women with PCOS and insulin resistance, where metabolic dysregulation compounds hormonal imbalance and impairs ovulation.
TCM View — Building Blood and Yin
In traditional Chinese medicine, spirulina's deep green-blue colour, its growth in water, and its dense nourishing quality associate it with the kidney and liver systems. It is a blood and yin tonic — replenishing the fundamental nourishing substances that are depleted by overwork, chronic illness, blood loss, or the natural ageing process. I recommend it as a food supplement for patients with blood deficiency patterns — characterised by pallor, fatigue, dizziness, poor sleep, and scanty periods — and for women preparing for conception who want to optimise their nutritional foundation.
How to Use Spirulina
Spirulina is available as a powder or tablet. A typical therapeutic dose is 3–5g daily. The powder can be added to smoothies or juices. It is best taken with food containing vitamin C to enhance iron absorption. It should be sourced from a reputable supplier that tests for heavy metal contamination, as algae can bioaccumulate toxins from polluted water. Spirulina is generally safe but is contraindicated in phenylketonuria and should be used cautiously in autoimmune conditions.
