Sun Chlorella is a brand of dietary supplements that contains a type of algae known as chlorella. Despite chlorella's benefits when eaten as a food, it is associated with side effects as a supplement.
Possible side effects of chlorella include diarrhea, nausea, flatulence, green stoools and stomach cramps. It also increases the sensitivity of your skin to the sun, posing a risk for sunburns.
Side effects of chlorella are most common during the first week of use while your body acclimates to the supplement, according to RxList.
Chorella contains vitamin K, which increases the clotting potential of blood, making it decrease the effectiveness of warfarin. This poses a risk for blood clots and may require a change in your dosage of warfarin, according to RxList.
Some patients develop severe, asthmatic reactions to chlorella. Symptoms include wheezing, rapid heart beat and chest pains, reports the Physicians' Desktop Reference.
If you are pregnant or nursing or if you suffer from lupus, multiple sclerosis or rheumatoid arthritis, it may not be safe for you to take Sun Chlorella due to its potential side effects. While taking Sun Chlorella, avoid tanning and use adequate sunscreen to protect your skin in case of photosensitivity.
