How Do Multivitamin Gummies Work? A Simple Guide

Multivitamin gummies work like any other supplement: they provide vitamins and minerals that the body absorbs mainly in the small intestine, after the gummy is chewed and swallowed. The difference is in the form — chewing breaks the gummy down and mixes it with saliva, which starts digestion earlier than swallowing a whole tablet. That does not mean they are "better" or "worse": it means the format changes the experience of taking them, not the biology of absorption.

What determines whether a multivitamin gummy makes sense for you is something else: which nutrients it brings, at what dose per serving, whether that dose comes close to what the evidence links to an adequate nutritional status, and whether you take it consistently. That is what this article explains — without promises and with the context of the numbers.

What happens in the body when you chew a multivitamin gummy

Unlike a tablet, which is swallowed whole, the gummy is chewed and broken down in the mouth. Saliva dissolves part of the gummy matrix (maltitol- and pectin-based, in the products in the range) and starts to release the nutrients. Then, in the stomach, the acidic environment continues to break the gummy down and, in the small intestine, the nutrients cross the intestinal wall into the bloodstream.

This route is common to tablets, capsules and gummies. Chewing does not "increase" absorption on its own, but it does ensure the gummy reaches the stomach already broken down — which matters above all for people who have difficulty swallowing tablets or avoid them for that reason.

Are the vitamins and minerals in gummies absorbed in the same way?

Not exactly, and it depends on the nutrient. Some factors that influence absorption:

• Vitamin B12: the oral route is a studied alternative to the intramuscular route in managing diagnosed deficiency, although the intramuscular route came out ahead in raising serum levels in a network meta-analysis of 13 studies with 4,275 participants ¹. This concerns people with a diagnosed deficiency, not those taking a multivitamin routinely.
• Zinc: the chemical form influences absorption. A 2024 narrative review suggested that zinc glycinate and zinc gluconate may be better absorbed than other forms of zinc in humans, although the comparative evidence is limited ². Dietary phytate (found in wholegrains and pulses) reduces the bioavailability of zinc ³.
• Biotin: in a crossover trial in 6 healthy adults, pharmacological oral doses of biotin were completely absorbed, with urinary recovery similar to that of the intravenous route ⁴.

In other words: the gummy matrix does not prevent absorption, but the nutrient, the chemical form and the rest of the diet all count.

What the label of a TuttiBear multivitamin gummy says

The Multivitamin Gummies provide, per serving of 2 gummies: 20 mg of vitamin C (25% NRV), 50 µg of vitamin D (1000% NRV), 4.5 mg of vitamin E (38% NRV), 0.4 mg of riboflavin (29% NRV), 2 mg of vitamin B6 (143% NRV), 10 µg DF of folic acid, 8 µg of vitamin B12 (320% NRV), 180 µg of biotin (360% NRV), 2 mg of pantothenic acid (33% NRV), 3 mg of zinc (30% NRV), 1 mg of omega-3 fatty acids (chia seed extract) and 100 mg of a blend of glycine, glutamic acid and L-glutathione. The directions for use state to chew 2 gummies per day, preferably after a meal.

Note that vitamin D appears at 1000% of the NRV per serving — a high dose relative to the reference value, which underlines the importance of not exceeding the recommended daily dose and of checking whether other supplements you take already contain vitamin D.

It is worth keeping the context of the reference values in mind: the EU NRV for vitamin D is 5 µg per day and the tolerable upper intake level set by EFSA for adults is 100 µg per day ^{5 6}. For zinc, the NRV is 10 mg and the upper limit is 25 mg per day ^{5 6}. For vitamin C, vitamin B12, biotin, riboflavin and pantothenic acid, EFSA has not set a tolerable upper intake level ⁶.

Do multivitamin gummies replace a balanced diet?

No. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle — this warning appears on the labels themselves. The role of a multivitamin is to complement, not to replace.

This is especially relevant in groups at higher risk of insufficient intake. A systematic review of 141 studies in adults following plant-based diets (mainly vegetarian and vegan) showed that the intake and status of vitamin B12, vitamin D, iron, zinc, iodine and calcium tended to be lower than in meat eaters, although results vary depending on the type of diet ⁷. In a meta-analysis of 17 studies in adult vegans, unsupplemented vegans had significantly lower serum B12 values and higher total homocysteine compared with vegetarians or omnivores ⁸.

If this is your case, it makes sense to talk to a healthcare professional about which nutrients to monitor. You can also go deeper in the article on how vitamin B12 works and in the guide to zinc: what the evidence shows.

What the evidence shows about the most common nutrients in these gummies

It is worth distinguishing what is well established from what is uncertain.

Zinc

Zinc is an essential micronutrient and is not stored in significant amounts, so regular intake is needed ⁹. Zinc deficiency can impair immune function and contribute to the global burden of infectious disease ¹⁰. In children with acute diarrhoea, a meta-analysis of 38 randomised trials suggested that zinc supplementation increased the proportion of children who recovered ¹¹ — but this applies to a specific clinical context, not to routine supplementation in healthy adults.

In a meta-analysis of 3 trials with 265 participants with prediabetes, zinc supplementation (20–30 mg/day, for 6–12 months) reduced fasting blood glucose in pooled analyses, both alone and in combination with other micronutrients ¹². Note that this is a population with a specific metabolic condition and doses higher than those of a typical multivitamin. The Multivitamin Gummies provide 3 mg of zinc per serving of 2 gummies; the Zinc Gummies have a different dose, which you can check on the product page. Doses used in studies are not instructions for use.

Vitamin B12

Vitamin B12 is essential for DNA synthesis, methylation and erythropoiesis. A systematic review and meta-analysis of 16 randomised trials with 6,276 participants found no effect of B12 supplementation (alone or in a B complex) on cognitive function, depressive symptoms or idiopathic fatigue in people without evident deficiency or advanced neurological disease ¹³. This matters: B12 corrects a deficiency, but it is not a "pick-me-up" for those who already have adequate levels.

To go deeper, see how to read the vitamin B12 label.

Biotin

Biotin is a water-soluble vitamin involved in macronutrient metabolism. The trial already cited showed complete absorption of pharmacological oral doses in healthy adults ⁴. A 2024 systematic review on micronutrients and androgenetic alopecia suggested that deficiencies or imbalances of B vitamins, vitamin D, iron and zinc may contribute to the pathogenesis of the condition and that supplementation showed potential benefits — but the results were not consistent across studies ¹⁴. This means biotin is not a guaranteed solution for hair loss; if the topic interests you, see biotin gummies for hair.

Authorised claims: what can be said accurately

In the European Union, only certain health claims are authorised for vitamins and minerals, under Regulation (EU) No 432/2012 ¹⁵. That is why, instead of vague promises, labels use formulations such as "Vitamin C contributes to the normal function of the immune system" or "Zinc contributes to the normal function of the immune system". For plants and botanical extracts there are no authorised claims — only what the studies examined is described.

Gummies or tablets: what changes in practice

Aspect	Gummies	Tablets
How to take	Chew	Swallow whole
Start of digestion	In the mouth, with chewing	In the stomach
Ease for those who have difficulty swallowing	Greater	Lesser
Typical excipients	Maltitol, pectin, citric acid	Variable
Common warning	Contains polyols; excessive consumption may have a laxative effect	Depends on the formulation

There are no studies directly comparing the bioavailability of gummies with that of tablets for most nutrients. What is known is that the nutrient, the chemical form and the presence of food at the time of intake influence absorption. If you want to go deeper into this comparison, see the article on zinc gummies or tablets.

How to get the most out of taking them

1. Follow the dose on the label. Do not exceed the recommended daily dose. In the case of the Multivitamin Gummies, that is 2 gummies per day.
2. Take after a meal. This is the product's own direction and it helps with the absorption of fat-soluble vitamins such as A, D, E and K.
3. Check for overlaps. If you take several supplements, add up the doses so you do not exceed limits — especially with vitamin D, which appears at high doses in some products.
4. Be consistent. The effect of a multivitamin depends on regular intake, not on a single dose.
5. Store correctly. Cool, dry place, out of reach of children.

Who should be careful

If you take medicines regularly, check with your doctor or pharmacist whether there are possible interactions before starting any supplement — some nutrients can interfere with the absorption or the action of medicines, and the reverse is also true.

In case of pregnancy, breastfeeding, illness or taking medicines, you should consult a healthcare professional before using any supplement — this warning appears on the labels in the range. The gummies contain polyols and excessive consumption may have a laxative effect. In the case of products with a high dose of biotin, biotin can interfere with the results of some laboratory tests; before having tests, tell your doctor and the laboratory that you take the supplement.

For children, there are specific formulations with age-appropriate doses and their own directions for use (for example, 1 gummy per day from 2 years of age, under adult supervision). Never give adult product doses to children. You can explore the Kids collection to see the available options.

Questions that remain unanswered

Research on gummy supplements is less extensive than on tablets and capsules. There are, for example, no trials directly comparing the clinical impact of a gummy multivitamin with that of an equivalent tablet. What exists is evidence on the absorption of individual nutrients and on the effect of correcting deficiencies — and that is what should guide your decision, together with the product label and, if needed, the guidance of a healthcare professional.

Frequently asked questions

Are multivitamin gummies absorbed by the body?

Yes. The gummy is chewed, broken down in the mouth and then digested in the stomach and absorbed in the small intestine, just as with other supplement forms. Absorption depends on the nutrient, the chemical form and the rest of the diet, not on the fact that it is a gummy.

Do multivitamin gummies work as well as tablets?

There are no studies directly comparing gummies with tablets for most nutrients, so it is not possible to state equivalence or superiority. What is known is that absorption depends on the nutrient and the chemical form, and that chewing makes them easier to take for people who have difficulty swallowing tablets.

When is the best time to take multivitamin gummies?

The direction for the products in the range is to chew after a meal. This helps with the absorption of fat-soluble vitamins such as A, D, E and K and reduces the likelihood of digestive discomfort. The most important thing is to keep a consistent routine.

Can multivitamin gummies replace a balanced diet?

No. Food supplements do not replace a varied and balanced diet or a healthy lifestyle. Their role is to complement the diet, especially in groups at higher risk of insufficient intake, such as people following plant-based diets.

Can children take multivitamin gummies?

There are specific formulations for children, with age-appropriate doses and directions to take under adult supervision. You should never give products formulated for adults to children. If in doubt, consult your paediatrician.

Are multivitamin gummies safe for long-term use?

As long as you respect the recommended daily dose on the label, yes. You should watch out for overlaps if you take several supplements, especially with vitamin D, and consult a healthcare professional in case of pregnancy, breastfeeding, illness or taking medicines.
