The benefits of spirulina and chlorella are more than evident, but are there any side effects? As with any drug or supplement, it is important to consult a physician prior to starting anything new. Spirulina and chlorella are naturally occurring whole foods and, generally speaking, do not cause any significant side effects.

Chlorella and spirulina are safe to be taken as whole food supplements, but some consumers have reported mild reactions. Side effects generally occurred within the first few days of adding these supplements to their diet. These side effects included:

  • Nausea
  • Bloating
  • Diarrhea
  • Green Colored Stool
  • Upset Stomach
  • Sensitivity to Sunlight
  • Headaches
  • Muscle Pain

The above side effects usually occur when a person first begins using spirulina and chlorella as a supplement and generally diminish as the body becomes adjusted. There are no documented reports of spirulina or chlorella negatively interacting with other foods or medications.

One of the great benefits of Chlorella is that it boosts the immune system, but if you have a condition such as multiple sclerosis, rheumatoid arthritis, or lupus, chlorella is not a supplement for you. These conditions are auto-immune diseases and chlorella could potentially worsen your condition.

As with any supplement, consult your physician if you are pregnant or breast-feeding. Even though our lab testing results show mercury levels are non-detectable, chlorella can have a high content of mercury, and it isn’t advised for women who are pregnant or breast-feeding.

In a very few cases, consumers have reported an allergic reaction to chlorella. The symptoms included breathing problems, chest tightness, hives, itching and/or a rash. These symptoms are considered major side effects and you should consult a physician immediately.

If you are currently taking blood thinners, namely Coumadin, or its generic Warfarin, you should not take chlorella. Chlorella may have high levels of Vitamin K ,which when combined with a blood thinner, could affect blood clotting.

Again, if you have any doubts or questions, it is wise to consult your physician.

Ensure that the supplement you are buying is from a reputable and qualified supplier, because spirulina and chlorella grown in contaminated water can concentrate toxins. For this reason, Perfect Aquatic Greens contains spirulina and chlorella that is grown in the exceptionally clean & natural environment of the Hainan Island.
