Spirulina

Spirulina is available in tablets, capsules or powder form, suitable for different nutritional needs and preferences regarding administration. 

In general, the formulations are lactose-free and well tolerated, making them suitable even for those with lactose intolerance.

Manufacturers – Spirulina Hofigal, Spirulina Alevia, Spirulina Bio Rotta Natura, Spirulina powder Niavis, etc.

Blue spirulina is recommended as a nutritional supplement in a variety of clinical and functional situations, such as:

• chronic fatigue, physical and mental exhaustion, asthenia
• low immunity and convalescence
• periods of intense stress, nervous and mental overload
• weight-loss diets and appetite control
• supporting digestion and normalising the gut microbiota
• combating oxidative stress and premature ageing processes
• improved physical and mental performance

Spirulina should be administered to adults in doses of 1–3 g per day, divided into 2–3 doses, approximately 30 minutes before main meals. For individuals undergoing intense physical exertion, the daily dose may be increased to 3–5 g, on the advice of a specialist. 

It is recommended to use the product in 3-month cycles, with breaks of at least 10 days between cycles.

The product is generally well tolerated. However, it is contraindicated:

• children under the age of 3
• people with hypersensitivity to any of the ingredients

Spirulina should only be used during pregnancy and breastfeeding on medical advice.

Caution is advised in cases of diabetes mellitus, coagulation disorders or autoimmune diseases, in which cases the advice of the treating doctor is required.

Spirulina may be taken alongside conventional medical treatments. An adequate intake of fluids (at least 2 litres per day) is recommended to optimise nutrient absorption. 

Due to its natural origin, there may be variations in colour, smell or appearance between batches, without this affecting the product’s efficacy.

At the recommended doses, spirulina has not been associated with any significant adverse reactions. 

Mild digestive discomfort or headaches may rarely occur. If you experience any side effects, stop taking the product and consult your doctor or pharmacist.

No significant clinical interactions are known. However, caution is advised when used concurrently with anticoagulants, antidiabetics or immunosuppressants.

Spirulina can be used alongside other supplements as part of a healthy, balanced lifestyle.

No documented cases of severe overdose associated with the intake of Spirulina have been reported; it is considered a dietary supplement with a high safety profile when used in accordance with the recommended doses. 

However, taking excessive amounts, significantly higher than the recommended daily doses, may cause temporary symptoms, particularly of a gastrointestinal nature, such as abdominal discomfort, bloating, nausea or changes in bowel movements. If symptoms persist or worsen, it is advisable to consult a doctor.

Store at room temperature (15–25 °C), away from moisture and direct light, in the original packaging. Do not use after the expiry date stated on the packaging. Keep out of reach of children.
