VITAMIN-C:Too much vitamin C or zinc could cause nausea, diarrhea, and stomach cramps.

SELENIUM:Too much selenium could lead to hair loss, gastrointestinal upset, fatigue, and mild nerve damage. 

VITAMIN-A:Symptoms of too much vitamin A include fatigue, suppressed appetite, nausea, dizziness, headache and dry skin. In severe cases, excess vitamin A may cause liver damage. It also may cause birth defects if taken during pregnancy.

VITAMIN-D:vitamin D daily may lead to high blood calcium levels. Side effects of excess vitamin D include fatigue, headache, loss of appetite, nausea and vomiting.

VITAMIN-E:High doses of vitamin E may cause hemorrhage and interfere with blood clotting.
