Walk into any pharmacy or scroll through any online shop and you’ll find dozens of collagen products – all claiming to be the best. But how do you actually compare them? The answer is on the label. Here is how to read it properly.
1. Check the Actual Collagen Content Per Serving
This is the single most important number. Look for the grams of collagen per serving – not the serving size, not the bottle volume, not the number of capsules.
- ✅ Good: ‘10g collagen hydrolysate per serving’
- ⚠️ Vague: ‘Collagen Blend 500mg’ (too low to be meaningful)
- ❌ Red flag: No collagen content stated at all
Many ready-to-drink collagen products contain only 2–5g of collagen per bottle despite a high price. Always calculate the price per gram of collagen to compare fairly.
2. Look for the Collagen Type and Source
The label should clearly state:
-
Type of collagen – e.g. Type I, Type II, Type III
-
Source – bovine (cattle), marine (fish), porcine (pig)
-
Form – hydrolysate / peptides / native collagen
If the source is not stated, that is a red flag. Allergen information (e.g. “contains fish”) is legally required in the EU and should always be present.
3. Check the Dalton Value (If Stated)
The Dalton (Da) value indicates the molecular weight of the collagen peptides. Lower values mean smaller peptides and better solubility. Premium products often state this clearly – e.g. ‘~1,000 Da’ or ‘~1,500 Da’. If no Dalton value is given, the product may use standard hydrolysate without further specification.
4. Read the Full Ingredient List
EU law requires all ingredients to be listed in descending order by weight. Check for:
-
Fillers – e.g. maltodextrin, dextrose (add bulk, not value)
-
Artificial flavours & sweeteners – e.g. sucralose, acesulfame K
-
Preservatives – e.g. potassium sorbate, sodium benzoate
-
Colouring agents – often unnecessary in a quality product
A short, clean ingredient list is generally a good sign. The fewer unnecessary additives, the better.
5. Look for Quality Certifications
Reputable manufacturers will state their production standards clearly:
- ✅ GMP certified – Good Manufacturing Practice (EU standard)
- ✅ Lab tested – independent testing for purity, heavy metals, microbiology
- ✅ Made in Germany / EU – subject to strict EU food supplement regulations
If none of these are mentioned, ask the manufacturer directly – or choose a brand that is transparent.
6. Check the Manufacturer Information
EU law requires the name and address of the responsible manufacturer or importer to be stated on the label. If this information is missing or vague, be cautious.
7. The Mandatory Disclaimer
Every EU-compliant food supplement must carry this statement (or equivalent):
“Food supplements are not a substitute for a balanced and varied diet and a healthy lifestyle. Do not exceed the recommended daily intake. Keep out of reach of children.”
If this disclaimer is missing, the product may not be fully EU-compliant.
