Side effects of dietary supplements
Dietary supplements help maintain optimal health and prevent complications related to vitamin and mineral deficiencies. However, if you do not research carefully and ignore the doctor's advice, you may experience side effects when using them.
Dr. Payal Chaudhary - senior consultant, obstetrician and gynecologist at Rainbow Children's Hospital (India) - shared some effects to note when using dietary supplements:
- Vitamin C is generally considered safe, but high doses can cause digestive problems such as diarrhea and stomach pain. It can also lead to a risk of developing kidney stones in at-risk people.
- Vitamin B12 supplements are generally well tolerated, but some people may experience side effects such as nausea, diarrhea or headache.
- Omega-3 supplements derived from fish oil can cause a fishy taste, bad breath, and indigestion. They can also increase the risk of bleeding in people taking blood thinners.
- Iron supplements can cause constipation, nausea, and stomach upset. In rare cases, they can lead to iron overload, especially in people with genetic conditions such as hemochromatosis.
“Other supplements such as herbal remedies, weight loss aids or hormone-based supplements can have potential side effects, including allergic reactions, hormone imbalances,” says Dr. Chaudhary.

Digestive disorders: Abdominal pain, bloating, nausea, diarrhea or constipation are common signs when the body cannot absorb dietary supplements.
Rash or itching: Some ingredients in dietary supplements can cause skin allergies, rashes, hives or itching.
