Purest Supplements with No Additives in the UK (2025 Guide)
If you’re searching for the purest supplements with no additives in the UK, you’re in the right place. At Clean Supplements UK, we formulate filler-free vitamins and use clear labels so you always know exactly what you’re taking — and what you’re not.
What “No Additives” Really Means
Many supplements include “other ingredients” such as flow agents and binders. These don’t add nutritional value and can pad out tablets. Common additives you’ll see on labels:
- Titanium dioxide (colour/whitener)
- Talc / stearates (flow & anti-caking agents)
- Artificial colours and coatings
- Excessive stabilisers or glazing agents
Our clean standard is simple: keep the ingredient list short, transparent, and focused on the active — delivered in a plant-based cellulose capsule wherever possible.
How to Read Supplement Labels (UK Buyer Checklist)
- Scan “Other Ingredients”: the shorter the list, the better. Avoid artificial colours and unnecessary flow agents.
- Check the capsule: look for vegetable cellulose capsules rather than heavy coatings or hard tablets.
- Demand clear dosages: avoid vague “proprietary blends”. You should see exact mg/µg per serving.
- Look for purpose, not padding: formulas should prioritise bioavailable forms, not additives.
