Biotin and Collagen Supplements: An Honest Buyer's Guide
Beauty supplements are everywhere, and the claims around them can be confusing. This guide to biotin and collagen supplements explains in plain words what the common ingredients are, the different formats, and what to check on the label, without hype.
Common ingredients explained
| Ingredient | What it is |
|---|---|
| Collagen peptides (hydrolyzed collagen) | Collagen protein broken down into smaller pieces. Listings often name the collagen types, such as I, II, III, V and X. |
| Biotin | A B vitamin (vitamin B7), found in many hair, skin and nail formulas. |
| Keratin | A structural protein found in hair and nails. |
| Glutathione | An antioxidant compound often combined with collagen. |
| Vitamin C | A vitamin commonly added to collagen formulas. |
Capsules, gummies or powder?
- Capsules: a measured dose, no taste, easy to travel with.
- Gummies: easy to take, but usually contain sugar. Keep them away from children, as they can look like sweets.
- Powder: mixes into drinks; the dose is measured with a scoop.
How to read the label
- Check the serving size and how many servings are in the pack.
- Read the full ingredient list, including fillers and allergens such as fish, shellfish or bovine sources.
- Follow the suggested use. Taking more than the label suggests is not recommended.
- Check the expiry date and storage instructions.
Safety points
- Talk to your doctor or pharmacist before taking any supplement, especially if you are pregnant, breastfeeding, taking medication or have a medical condition.
- Biotin can affect some lab test results. Tell your doctor if you take biotin before any blood test.
- Stop taking a supplement and seek medical advice if you have any reaction.
- Keep all supplements out of reach of children.
