Spirulina is a health supplement made from blue-green algae. It is believed to have antibacterial, anticancer and probiotic properties. It is used to treat a variety of conditions and may help to promote good heart health and liver function and support the respiratory and immune systems. Although considered safe for most people, spirulina may have a few health risks worth considering before using it in regularity. Here are the side effects of spirulina:
People with weak or malfunctioning kidneys may not want to take spirulina. Spirulina has been associated with swelling of the extremities and other parts of the body tissue, also known as edema.
Some people have experienced slight elevations in body temperature when taking spirulina. Although it is not likely to cause dangerous spikes in body temperature, prolonged mild fevers and high fevers may be possible. Consult a doctor should these conditions appear and persist.
Spirulina can cause mild digestive problems such as abdominal pain, gas and constipation. It is believed that spirulina can contribute to the buildup of toxins in the colon. Be sure to drink plenty of fluids when taking spirulina to help properly flush the body of potentially hazardous substances.
Spirulina can sometimes be contaminated with toxic metals, bacteria and other substances that can damage the liver. This can lead to stomach pain, nausea and vomiting. While this is considered a small risk, consult a doctor should any of these side effects occur. Spirulina is not recommended for children who may be more susceptible to these conditions.
