Supplements Without Fillers UK (2025 Guide)

More UK customers than ever are searching for supplements without fillers. If you’ve flipped over a supplement label and seen ingredients like magnesium stearate, silicon dioxide, maltodextrin, or titanium dioxide, you might be wondering — are these really necessary?

The truth: most fillers are used to bulk out capsules or speed up manufacturing. They don’t provide any health benefit. That’s why a new wave of filler-free supplements is rising across the UK — and customers are switching fast.

What Are Fillers in Supplements?

Fillers (also called excipients, bulking agents, or flow agents) are added to make capsules easier to produce. Common examples include:

• Magnesium stearate — used as a lubricant, no nutritional benefit
• Silicon dioxide — anti-caking agent
• Maltodextrin — cheap starch filler
• Titanium dioxide — a whitening/colouring agent (banned in EU food)

While legal, many consumers prefer to avoid these unnecessary additives in favour of pure, transparent nutrition.

Why UK Consumers Want Filler-Free Supplements

• ✅ Purity — nothing hidden, only the nutrients you need
• ✅ Better absorption — no cheap bulking agents that dilute potency
• ✅ Transparency — clear labels without misleading blends
• ✅ Trust — independent COAs prove what’s inside
