All the tablets you mentioned were dietary supplemants which help to replenish the reduced store of calcium present in the body.Shellcal is a dietary supplement that contains Calcium, thus the only reported known side effect of it is constipation. Evion contains Vit E which at it's usual dose is rarely toxic.High doses however can cause nausea, diarrhea, stomach cramps, fatigue, weakness, headache, blurred vision, rash, and bruising and bleeding. Freeflex Forte is actually not a drug, it is a supplement that contains Glucosamine and Chondroitin, which are substances that are naturally present in our joints. It is commonly believed that a lack of them, due to aging or injury can cause joint problems and pain, and that replacing them can help with those conditions. Since it is a supplement, not a drug, the side effect profile has not been studied and I can't really answer your question. Please take all the drugs prescribed your doctor without worrying about the side effects.Hope,I satisfied your queries.
