Gummies vs Capsules: Which Supplement Format Is Actually Better?
When choosing a supplement, most people focus on the ingredients. However, the format — gummies vs capsules — plays a major role in ingredient stability, absorption, formulation quality and transparency.
At SellHealth UK, we can manufacture both gummies and capsules at the same price. After extensive consultation with our factory and formulation partners, we made a deliberate decision to prioritise capsules.
Gummies vs Capsules: A Quick Comparison
| Feature | Capsules | Gummies |
|---|---|---|
| Active ingredient strength | High | Limited |
| Heat exposure during production | Low | High |
| Fillers or sugars required | No | Almost always |
| Suitable for micronised ingredients | Yes | Rare |
| Vegan options | Yes | Sometimes |
| Ingredient stability over shelf life | Strong | Variable |
1. Ingredient Strength & Stability
Capsules allow for higher concentrations of active ingredients and better protection from heat, moisture and oxygen. This makes them particularly suitable for vitamins, minerals, amino acids and botanicals that are sensitive to environmental stress.
Gummies require heating during production and must prioritise texture and taste. This limits how much active ingredient they can contain and can lead to degradation both during manufacturing and over shelf life. For many formulations, our factory advises that capsules are simply the more stable and reliable option.
2. Why So Many Companies Push Gummies
Gummy supplements have become extremely popular — largely because they are a trend.
Many companies push gummies because they:
- are visually appealing and easy to market on social media
- taste good and feel more like a treat than a supplement
- require less explanation than capsule-based formulations
While gummies can help with consistency for some people, their popularity is driven more by consumer trends than by formulation performance. Capsules remain the preferred format in clinical, practitioner and pharmaceutical-grade supplementation for a reason.
3. Fillers, Sugars & Formulation Trade-Offs
Most gummy supplements require additional ingredients to achieve the correct texture and flavour. These typically include sugars or sweeteners, gelling agents such as pectin, flavourings, colourings and stabilisers.
Even products labelled as “sugar-free” often rely on bulking agents that add volume without adding functional value.
At SellHealth UK, we take a different approach:
- no fillers
- no sugars or bulking agents
- 100% vegan capsule shells
- ingredients included for function, not flavour
4. Absorption & Bioavailability
Capsules allow for the use of micronised ingredients, which have a smaller particle size and increased surface area. This can support more predictable breakdown and absorption in the digestive system.
Gummies dissolve alongside sugars and gelling agents, which can influence how active ingredients are released. This makes consistent absorption more difficult to achieve, particularly across different batches and over shelf life.
5. Lab Testing: The Reality with Gummies
Lab testing is often highlighted in supplement marketing, but the reality is more complex — especially for gummy formats.
In practice, comprehensive lab testing for gummy supplements is often limited or not practically achievable across the industry. This is because:
- sugars and gelling agents create complex matrices that are difficult to analyse accurately
- many analytical methods are validated for powders and capsules, not gummies
- active ingredients in gummies can degrade during production and over shelf life
- end-of-shelf-life testing can produce variable results
As a result, extensive testing is often limited or not required in practice for many gummy products. Capsules, by contrast, are simpler to analyse and verify due to their cleaner composition and improved stability.
6. Why SellHealth UK Chooses Capsules
We choose capsules because they allow us to:
- avoid fillers entirely
- use vegan shells only
- include micronised ingredients where appropriate
- maintain ingredient integrity over shelf life
- focus on formulation quality rather than trends
Final Thoughts
Gummies are popular, but popularity does not always equal effectiveness. If your priority is ingredient integrity, absorption and transparency, capsules remain the more reliable option.
At SellHealth UK, we don’t follow trends — we focus on sound formulation choices.
Frequently Asked Questions
Are gummies as effective as capsules?
In many cases, capsules are more effective because they can hold higher ingredient concentrations and avoid heat-related degradation.
Why do so many supplement brands sell gummies?
Gummies are trend-driven and popular with consumers. Many brands choose them for marketing appeal rather than formulation performance.
Is lab testing required for gummy supplements?
Comprehensive lab testing for gummies is often limited due to their complex composition. Many testing methods are not validated for gummy matrices.
Are SellHealth UK supplements vegan?
Yes. All SellHealth UK supplements use 100% vegan capsule shells and contain no fillers.
Do capsules absorb better than gummies?
Capsules often provide more predictable absorption, particularly when using micronised ingredients and cleaner formulations.
