Almost all glucosamine on the UK market is derived from shellfish — which rules it out for anyone with a shellfish allergy, and for vegans and vegetarians. Flexi-Time uses vegan-source glucosamine hydrochloride at 300mg per capsule, alongside MSM, 2631mg of turmeric providing 50mg of curcuminoids, and twelve further botanicals and enzymes.
Vitamin C Carries the Cartilage Claim
Glucosamine and MSM are widely used in joint formulas but carry no EU-authorised health claims. What does carry one here is vitamin C: it contributes to normal collagen formation for the normal function of cartilage and bones — along with blood vessels, gums, skin and teeth.
Collagen is the structural protein in bones, cartilage, gums, skin, tendons and blood vessels, and vitamin C is a required co-factor for its synthesis. That is the regulator-assessed mechanism behind this formula.
The turmeric is the headline botanical at 2631mg equivalent per capsule, standardised to deliver 50mg of curcuminoids — the active polyphenols in turmeric.
How Other UK Joint Supplements Compare
Standard glucosamine and chondroitin — shellfish-derived. The category default, from Seven Seas to own-brand. Effective for many, but shellfish-sourced, which excludes anyone with a shellfish allergy or on a plant-based diet, and rarely halal certified.
Single-ingredient turmeric capsules — one botanical. Inexpensive, but turmeric alone with no glucosamine, MSM or vitamin C carrying the cartilage claim.
Premium joint blends — good quality, higher price. Often well formulated but typically shellfish-based and without halal approval.

How to Take It
Take 1 capsule, two to three times per day, preferably with food. Joint nutrients are cumulative rather than acute — give it several weeks of consistent use.
For higher-dose turmeric specifically, CurcuminBoost is the dedicated organic option. For collagen itself, Marine Collagen Nourish provides 9,000mg of marine peptides per serving — though note that one contains fish.
Is This You?
- You have a shellfish allergy, or follow a plant-based diet, and standard glucosamine is off the table
- You need halal approved joint support — shellfish-derived glucosamine rarely carries it
- You want turmeric at a meaningful dose with the curcuminoid content stated, not just "contains turmeric"
- You'd rather have fourteen ingredients at declared doses than glucosamine alone
- You want a regulator-approved cartilage claim behind the product, via vitamin C

Questions We Get Asked
Is the glucosamine from shellfish?
No. Almost all glucosamine sold in the UK is derived from shellfish shells, which makes it unsuitable for anyone with a shellfish allergy and for vegans and vegetarians. The glucosamine hydrochloride in Flexi-Time is vegan-sourced, at 300mg per capsule. That is the main reason this formula exists.
Which ingredient carries the authorised claim?
Vitamin C. It contributes to normal collagen formation for the normal function of cartilage and bones — an EU-authorised health claim. Glucosamine and MSM are widely used in joint formulas but carry no authorised claims of their own, and we would rather be clear about that than imply otherwise.
How much turmeric is in it?
2631mg equivalent weight from extract per capsule, providing 50mg of curcuminoids — by far the largest ingredient in the formula. If turmeric is your main interest, CurcuminBoost is our dedicated organic turmeric product.
What do bromelain and papain do here?
They are enzymes found in fruit — bromelain from pineapple, papain from papaya. Both are included at 5mg alongside the botanicals. They are a traditional inclusion in joint formulas rather than ingredients carrying authorised claims.
