A serve is four veggie capsules, which gives 1,500 mg of glucosamine, 1,200 mg of chondroitin sulfate and 1,000 mg of MSM as OptiMSM. The bottle holds 120 capsules, so it lasts 30 days. It contains shellfish, so it is not suitable if you have a shellfish allergy.

What is in it
Glucosamine. A compound your body makes naturally and uses as a building block of cartilage. The glucosamine here comes from crab and shrimp shells.
Chondroitin sulfate. Another natural part of cartilage. It is often paired with glucosamine.
MSM. Methylsulfonylmethane, a source of sulfur. OptiMSM is a branded form.
The other ingredients are hypromellose (the vegetarian capsule), magnesium stearate from a vegetable source, silicon dioxide and microcrystalline cellulose.
What the research says. Glucosamine and chondroitin are among the most studied joint supplements, mostly in knee osteoarthritis. Results are mixed. Some trials show a small benefit and others show none, so it is fair to treat this as a supplement to trial for a few months, not a treatment.
Who it suits
