When gummy vitamins entered the market, they were a hit with kids and adults alike. They’re tasty and make life way easier for anyone who has a tough time swallowing traditional capsules and pills. In fact, the brightly-colored supplements make taking your vitamins as fun as indulging in a piece of candy — and this, according to University Hospitals primary care provider Monique Williams, CNP, “significantly improves adherence to a daily supplement routine.”

Still, it’s not all sunshine and cotton candy when it comes to gummy vitamins. According to some experts, the appeal of this type of supplement hides quite a few potential downsides.

“While gummy vitamins have their place, they shouldn’t be the default option for most people,” says Avery Zenker, MAN, RD at MyCrohnsandColitisTeam. So at the end of the day, are gummy vitamins good for you? Here are the major concerns Zenker and other experts caution against.

1. Gummy vitamins may contain fewer nutrients than other supplements.

While both medicine and supplements are regulated by the FDA, the rules governing the latter are far less strict. As a result, Zenker notes that not everything is always as it seems when it comes to these chewy vitamins. According to a 2022 study in the American Journal of Nursing, labeling on dietary supplements is often inaccurate and misleading — and according to our experts, this holds particularly true for gummy vitamins¹.

Certain nutrients in particular are difficult to incorporate into a stable gummy. These include calcium and magnesium, which require large amounts of mineral salts, as well as iron and B vitamins, whose flavors are often bitter, metallic, and difficult to mask. Consumer Labs tests have found that, as a result, some gummies contain less of certain nutrients than what’s on the label².

While this isn’t necessarily harmful, it’s certainly not a win for fans of these tasty supplements. According to Zenker, this means “some gummy vitamins are more like expensive candy.”

2. Gummy vitamins tend to lose potency over time.

While some gummy vitamin brands do indeed start out with a respectable amount of nutrients, what’s on the label could still be misleading due to gummies’ propensity to degrade at a rapid rate.

“Supplements are less stable (chemically) in a gummy formulation,” explains Dr. Hedva Barenholtz Levy, a pharmacist, author, and educator with over 25 years’ experience. Heat and humidity can also break down the vitamins in gummies more quickly than in coated pills. According to Emma Zheng, a certified nutritionist, HR expert, and co-founder of SummitBreezeTea.com, this is particularly true of compounds like vitamin C and folate. She says these compounds “tend to break down more easily in vitamin gummies because of their texture.”

“Vitamin C and folate break down when exposed to heat, air, and light,” she explains. “By the time people get to half empty, the vitamin may not be as potent as it was when it was first purchased.”

While storing them in a cool, dry place can extend their shelf life, it’s not foolproof. Ultimately, they may not be worth the added cost when compared to more stable supplement pills.

3. On the flip side, gummy vitamins may contain way more of a nutrient than you think.

To defend against degradation, some companies may overcompensate and jam even more active ingredients into their formulations. This means that even if you’re using the vitamins responsibly, there’s a chance you’re getting more nutrients than you thought. Overall, you can see that the only consistent factor of gummy vitamins is their inconsistency.

“Manufacturers want to maximize the amount of active ingredient in the formulation in order to maximize the shelf-life of the product,” says Levy. “Gummy formulations of vitamins might be less potent OR more potent than a tablet or capsule formulation.”

Consumer Labs tests found that certain gummy vitamins could contain twice or even three times as much of a given nutrient than it says on the label². At best, this is misleading and unpredictable. At worst, this can have dangerous repercussions.

4. The palatability of gummy vitamins may lead to misuse.

Naturally, this leads us to the question: can you overdose on gummy vitamins? Gummy vitamins are designed to be as tasty as candy — and unfortunately, this can lead us to forget that they’re medicine, and that there are dosages to respect. “Because of the candy-like appearance of gummies, overdose is a real concern,” says Levy.

So what happens if you eat too many gummy vitamins? Of course, in some cases, overconsumption isn’t that big of a worry. The biggest consequences you face might be expensive pee. But when it comes to certain vitamins and minerals, overconsumption can actually be dangerous. For example, you may think water-soluble vitamins are harmless and can’t be consumed in excess — but that’s not necessarily true.

While vitamin C has low toxicity, it can cause gastrointestinal symptoms like diarrhea, cramps, and nausea when taken at high doses³. Vitamin B3 (niacin) can cause high blood pressure, impaired vision, and even liver damage if taken in too high a dose⁴. Vitamin B6 can cause neurological symptoms and light sensitivity when taken at high doses⁵, while too much folate can have negative impacts on the immune system⁶.

And these dangers are only compounded when you take too much of fat-soluble vitamins and minerals like Vitamins A, D, and E, which build up in the body if taken in large quantities. In these cases, repercussions can include hemorrhage and stroke (vitamin E⁷), organ damage (vitamin D⁸), and even strokes (vitamin A⁹).

5. Gummy vitamins often contain added sugar or sugar alcohols.

To help make gummy vitamins tastier, most brands rely on sweeteners — either sugar or sugar alcohols like sorbitol. And both approaches have their downsides.

Sugar-sweetened gummy vitamins contain anywhere from three to five grams of added sugar per gummy, TODAY.com reports¹⁰. “Taking a serving of gummy vitamins every day could provide the same amount of sugar as an extra can of soda every week,” says Zenker. That can easily compound.

For those taking more than one supplement a day, that sugar adds up fast. Since the American Heart Association recommends limiting added sugar to somewhere between 25 and 37 grams a day, you may find yourself needing to cut out other, more pleasant sources of added sugar, like good-quality dark chocolate or homemade vegan ice cream.

The added sugar of gummy vitamins only contributes to their negative impact on your dental health, according to Dr. Tricia Quartey, a Brooklyn-based dentist and spokesperson for the American Dental Association. “Gummy vitamins are still just candy,” she tells TODAY.com. “And they’re sticky, which is the worst type of candy.”

To get around this issue, many brands rely on sugar alcohols instead. But while this addresses the issue of added sugar, these additives aren’t without their own set of concerns. Sorbitol can cause gastrointestinal discomfort or distress. Compounded with other additives like guar gum, which has also been linked to digestive woes¹¹, and artificial dyes, which can have endocrine and neurological side effects, your gummy vitamin may be causing more trouble than it’s worth.
