🏷️ What to Look for on a Supplement Label (and What to Avoid)

👀 Why label-reading matters more than ever

The UK supplement market is booming — but not every product on the shelf is as “healthy” as it looks. Hidden inside many capsules and powders are fillers, artificial additives, and chemical binders that offer zero nutritional benefit.

That’s why at Luthco, we do the label-reading so you don’t have to. But if you want to understand what goes into your body, this quick guide will help you decode supplement labels and make smarter choices.

✅ What to look for on a supplement label

When choosing clean supplements, the goal is simplicity + transparency. Here are the green flags that show a product has been made with integrity:

1️⃣ Clear, honest ingredient lists– Every active ingredient should be listed in plain English — no “proprietary blends.”– Look for transparency around quantities (e.g. “Ashwagandha root extract 500 mg KSM-66”).

2️⃣ Natural sources and plant-based ingredients– Choose products labelled plant-based or vegan-friendly.– Look for whole-food or naturally derived ingredients rather than synthetic versions.

3️⃣ Free from artificial additives– Labels should say “no artificial colours, flavours, or preservatives.”– “Non-GMO” and “additive-free” are strong indicators of a cleaner formula.

4️⃣ Sustainably produced in the UK or EU– UK-manufactured supplements follow stricter quality standards.– Locally made also means fewer transport emissions and better oversight.

5️⃣ Evidence-backed ingredients– Look for named extracts with standardised actives (like KSM-66®, BioPerine®, or OptiMSM®).– This shows clinical data supports their inclusion — not marketing hype.

⚠️ What to avoid on supplement labels

Even products that look premium can hide less-than-pure additives. Here’s your quick “no-go” list — ingredients that never appear in Luthco’s zero-toxin wellness range:

🚫 Titanium dioxide — a whitening agent banned in foods across the EU due to safety concerns.

🚫 Magnesium stearate — a cheap flow agent that can reduce nutrient absorption.

🚫 Silicon dioxide — an anti-caking additive that does nothing for your health.

🚫 Artificial colours or sweeteners — look out for E-numbers like E171, E172, E104, and E951 (aspartame).

🚫 Hydrogenated oils or talc — unnecessary bulking agents sometimes used in tablets.

🚫 Proprietary blends — vague formulas that hide ingredient dosages.

At Luthco, we believe every label should tell the truth — no jargon, no fillers, no shortcuts.
