Spirulina is a dietary supplement that is considered safe for most people when consumed in adequate amounts. However, it is important to keep a few precautions in mind: 1. Consult your doctor before starting Spirulina supplements, especially if you have any pre-existing medical conditions or are taking other medications. 2. If you experience any allergic reactions, such as rashes, itching, difficulty breathing or swelling, stop taking the product and seek medical attention immediately. 3. Avoid taking Spirulina if you are pregnant or breastfeeding, as its safety in these situations has not been established. 4. If you have phenylketonuria, an inherited metabolic disease, you should avoid Spirulina, as it contains phenylalanine. Remember that it is always important to read and follow product instructions and consult a healthcare professional before starting any dietary supplement.
