Your gummy supplement might be shortchanging you on nutrients

A mix of multivitamin and magnesium gummies
Set as preferred source

Gummy vitamins are a popular alternative to tablets, but in some cases we found you could be getting much less of the key ingredients than you might expect, while paying more for the privilege.

Certain types are more likely to run into issues than others. For example, a vitamin D gummy will likely give you what you need, albeit in a pricier format, but when we looked into multivitamin and magnesium gummies, we found that you could end up shortchanged on nutrients as well as cash.

Gummies and spray vitamins have become increasingly popular in recent years. For those who struggle with swallowing pills, they can be a real help - although as with any fancy formats, they'll usually cost you more. 

But they have downsides too. Gummies typically have more additives and sugar than tablets, and in some cases you could be missing out on important nutrients or getting a lower dose than anticipated, without realising. 

Gummies and sprays may contain less active ingredients than tablet equivalents

A range of popular multivitamin gummies

We reviewed a range of popular multivitamin and magnesium gummies and sprays, to find out how they compare to pill versions. Our research shows you'll almost always pay more, and in many cases for less of the active ingredients you want.

Our analysis of multivitamin supplements rates them for completeness against 23 key nutrients we'd expect to find in a general multivitamin. Most tablets and capsules contain near this number – or exceed it.

But among the popular gummies and sprays we assessed, the most any contained was 14. The least was seven, so less than a third of the range of nutrients found in a typical pill version. 

More additives and sweeteners

Compared to most tablets and capsules, gummies typically contain more additives and fillers, as the manufacturers need to make something that is sweet-like in texture and taste. 

Common fillers are gelling agents so the gummy holds its shape, as well as sugar, sweeteners and flavourings to make it taste nice, and stabilisers so that the nutrients don't deteriorate and the gummies don't stick together. 

This means there's less space to include valuable nutrients. With multivitamins, we found that, even where the nutrients are included, many of them are in low doses. 

For example, New Leaf Multivitamin Gummies contain just 1.5mcg of vitamin D – 15% of the 10mcg recommended by the NHS. Many other multivitamin gummies we looked at contained just 5mcg of vitamin D – half the recommended amount. 

Minerals fare badly too, and were largely absent from the multivitamin gummies we reviewed. Key nutrients, including calcium and magnesium, were missing completely. This is likely because they're needed in relatively large amounts - 800mg for calcium and 375mg for magnesium. 

Probably for the same reason, we found that standalone magnesium gummy supplements also tend to be underdosed compared with capsule or tablet versions.

Boots Multivitamin tablet vs gummy

Boots multivitamin tablets and gummies side by side


Cost per daily doseContains
Boots A-Z Multivitamin tablets7p23 nutrients at good dose levels
Boots Multivitamin gummies15p9 vitamins at lower-than-optimal dose levels

Boots A-Z Multivitamin tablets cost 7p per daily dose and contain 23 nutrients, including essential vitamins and minerals. Most nutrients are at doses that fulfil your daily needs, including 10mcg of vitamin D.  It contains all 13 vitamins and 10 minerals, including copper, iodine, iron and zinc. The only nutrients that don't meet your full daily needs are calcium (25%) and magnesium (27%).

In comparison, Boots Multivitamin gummies cost 15p per daily dose and contain nine vitamins (A, B6, B7, B9, B12, C, D and E) but none in doses that meet your daily requirements - doses range from 25% (vitamin B5) to 60% (folic acid, vitamin B9). They also contain 20 additives - including five different forms of sugar and sweeteners - compared with 10 in the tablets.

If we put it through our multivitamins ratings framework, which assesses supplements on range of nutrients, dose levels, bioavailability and additives, the Boots Multivitamin gummies score just 15%. In fact, the scores for all the multivitamin gummies we put through our assessment were so poor we decided not to include them in our multivitamin reviews.

How other multivitamin gummies measure up:

  • Bassetts Adult Multivitamin gummies (£13.65 for 60, 23p per daily dose): Contains seven nutrients - vitamins A, B2, B6, B12, C, D and E (and only 5mcg of vitamin D, which doesn't meet the 10mcg recommended by the NHS). 
  • Bettervits Multivitamin gummies (£30 for 60, £1 per daily dose): Contains nine nutrients - vitamins A, D, E, C, B3, B6, B7, iodine and zinc. A daily dose is two gummies.
  • Capys Adult Multivitamin gummies (£14.99 for 260, 12p per daily dose): Contains 10 nutrients - some B-vitamins plus vitamins A, C, D and E, and zinc and iodine, the majority in decent doses. A daily dose is two gummies.
  • HABI All Set Multivitamin gummies (£10 for 60, 33p per daily dose): Contains 10 nutrients - vitamins A, B3, B6, B7, B12, C, D and E, plus zinc and iodine. It contains 10mcg of vitamin D and 2.5 mcg of vitamin B12, 100% of what you need per day but for all other nutrients it provides 50% of your daily needs. Also contain 17 additives and fillers including six different types of sugar and three flavourings. 
  • Holland & Barrett Multivits gummies (£11.99 for 60, 20p per daily dose): Contains 10 nutrients - vitamins A, C, D and E plus five B-vitamins and iodine. It only contains 5mcg of vitamin D, half of what the NHS recommends. 
  • Nature's Truth Multivitamin gummies (£9.99 for 60, 33p per daily dose): Contains 12 nutrients - vitamins A, C, D and E, B5, B6, B7, B9 and B12 plus zinc, iodine and chromium. It does contain 10mcg of vitamin D.
  • New Leaf Multivitamin gummies (£13.95 for 60, 47p per daily dose): Contain 13 nutrients - a mix of vitamins and minerals which appears promising but the doses aren't great. These contain only 1.5mcg of vitamin D, 15% of what you need. Doses of zinc, manganese and chromium are similarly low.

Magnesium tablets vs gummies

Magnesium gummies and supplements from Holland & Barrett

While some single-active gummies fare better – such as vitamin D gummies, which generally will meet the required daily dose level – we found magnesium gummies are another one to watch out for. 

All the magnesium gummies we assessed contained low doses compared to magnesium tablets or capsules, and don't meet the daily recommended amount for adults.

Daily doses varied between 75 and 300mg of magnesium, with the most common dose sitting at around the 150mg zone. This is less than half the nutrient reference value (NRV) of 375mg - the recommended amount to aim for. 

They also typically use magnesium citrate, which can have some unwanted digestive side effects versus other forms of magnesium.

Take Holland & Barrett's own-brand offerings. The gummy version costs 63p per daily dose, but provides only 150mg of magnesium. The tablet version costs 30p per daily dose and contains 300mg of magnesium. The only downside? You have to take three tablets per day to get the full dose.

Among the 10 other magnesium gummy supplements we assessed, the cost of a daily dose varies between 22p and £1.33, and the dose level varied wildly too, for example:

  • Nutrigums Magnesium gummies cost 22p for one gummy, but contain just 75mg magnesium per dose.
  • Starpowa Magnesium Super Strength gummies were the most expensive at £1.33 per two-gummy dose, which provides 206mg of magnesium.
  • Vitabiotics Ultra Magnesium gummies cost 60p per daily dose (two gummies) and provide 300mg of magnesium. 

Whereas we've found a Best Buy magnesium supplement that costs 17p per daily dose and provides 400mg of magnesium.

What about vitamin sprays? 

A selection of multivitamin oral sprays

Like gummies, multivitamin sprays don't fare well when compared to tablets. The multivitamin sprays we looked at contain 13-14 nutrients compared to 23 typically found in tablets. 

As with the gummies, doses of individual nutrients vary, but the Better You spray was generally quite well-dosed for the nutrients it contained.

  • BetterYou Multivitamin oral spray (£10.99 for 32 doses, 34p per daily dose): Contains 14 nutrients - vitamins A, C, D, K, some B-vitamins, selenium and iodine. Most of these are well-dosed and it contains 20mcg of vitamin D.  
  • Natures Aid Multivitamin oral spray (£9.99 for 60 doses, 17p per daily dose): Contains 13 nutrients - the full range of vitamins, however, some in very low doses. For example, it contains only 12.5% of your vitamin A and C daily needs. It does, however, contain your daily needs for vitamin D (10mcg) and vitamin B12 (2.5mcg).

Sprays also require a lot of additives to make them palatable, including flavourings and sweeteners such as xylitol. While xylitol can cause digestive issues at large doses, at the doses found in these sprays it's unlikely to be problematic. 

As with gummies, for some these may be the preferred or only option, but it's worth checking the ingredients to ensure you're getting the nutrients you really need in the right doses if you're trying to make up for a specific deficiency. 

And if you don't have absorption issues or issues swallowing pills, you're likely to be better off with a tablet.

The verdict on gummy and spray supplements

A selection of supplements in tablets, capsules and gummies

While gummy and spray formats are beneficial for some, they can have drawbacks including higher prices, more additives and smaller amounts of active ingredients than you might expect.

If you can swallow pills, you'll be better off with a tablet or capsule in most cases, especially for heavier minerals or combination products such as multivitamins and magnesium. 

While we have two Best Buy multivitamins and two Great Value options no gummies or sprays scored highly enough for us to recommend them. The same applies to our review of magnesium supplements. 

For multivitamins, the sprays we reviewed do score better than gummies, but both gummies and sprays contain mainly vitamins rather than minerals, and most of these are easy to get through a healthy diet anyway. 

For example, most people get enough vitamin A from sources such as dairy, eggs, oily fish, carrots, sweet potatoes, red and yellow peppers and dark green leafy veg. The same applies to vitamin C, which is found in citrus fruits, berries, tomatoes, potatoes and broccoli. 

The exception is vitamin D, which is hard to get from diet alone, and vitamin B12 for vegans. 

What's missing from multivitamin gummies and sprays are important nutrients such as iron, calcium and magnesium that many people in the UK struggle to get enough of. 

Always check the back of the pack when buying a multivitamin, whether that's a tablet, capsule, spray or gummy, to make sure it contains the nutrients that you need most.
