Supplements Without Additives: The Honest UK Buyer’s Guide (2025)
If you’re looking for supplements without additives or fillers in the UK, you’ve probably noticed how many products on the shelves are bulked out with talc, binders, coatings and colourants. At Clean Supplements UK, we built our entire brand around being different — filler-free, clean, and transparent. This guide explains what additives to avoid, how to spot them on labels, and which clean supplements are worth your money.
What Additives Are Hiding in Your Supplements?
Here are the most common unnecessary ingredients found in high street vitamins:
- Titanium Dioxide: a whitening agent, banned in EU food but still found in UK supplements.
- Magnesium Stearate: used as a flow agent, offers no health benefit.
- Talc: used for anti-caking, adds nothing to nutrition.
- Artificial Colours & Glazing: purely cosmetic, often listed as “coating” or “E-numbers.”
Why Avoid Additives?
- ❌ They dilute potency — space that should be active nutrition is wasted.
- ❌ Some are controversial (e.g. titanium dioxide linked to health concerns).
- ❌ They hide behind vague “Other Ingredients” lists, reducing transparency.
That’s why supplements without additives are rapidly growing in demand across the UK.
How to Spot Supplements Without Additives
Use this UK buyer checklist:
- ✅ Short ingredient lists — ideally just the active ingredient + capsule.
- ✅ Plant-based cellulose capsules — no gelatin or coatings.
- ✅ No “proprietary blends” — dosages should be clearly stated in mg/µg.
- ✅ Transparent UK brands with consistent reviews.
