However, multivitamins can't replace a balanced diet, and taking them in large quantities can cause side effects ranging from mild stomach upset to serious liver and heart problems. Like many supplements, multivitamins aren't strictly regulated and can contain much higher levels of nutrients than the label says. A study found that calcium supplements may increase the risk of a heart attack. Many doctors recommend that people at high risk of heart disease get their calcium through diet and not through supplements.
Okunnu says, “On average, I would say no.” Okunnu poses a question: For the average person who isn't really deficient, does consuming more of these vitamins and minerals than you need actually benefit your overall health? The good news is, even when all they produce is expensive urine, what they won't cost you is your health. According to Dr. Okunnu, some multivitamins are better than others. And if they're worded incorrectly, they can even be unsafe.
As for which form of a multivitamin is better: capsules, tablets, gummies, or liquids, Dr. Okunnu says there's really no difference.
