Supplements for joints
Collagen peptides, vitamin C, hyaluronic acid, omega 3 and vitamin D3 K2: the authorised claims, the trial timelines, and what nothing here does.
How to choose a joint supplement
Freer movement and more comfortable joints, with skin that benefits too. Collagen and vitamin C support the tissues joints are made of, hyaluronic acid cushions them, omega 3 eases stiffness with regular use, and vitamin D keeps the muscles around them strong.
Why these
Classic Collagen: Supports smoother skin and more comfortable joints, with the trials showing change at around 90 days. Hydrolysed peptides, unflavoured.
Collagen Formula: Helps the body build its own collagen: vitamin C with the amino acids it needs, in a capsule.
Hyaluronic Acid Capsules: Cushions joints and hydrates skin from within. 200 mg per capsule, the high molecular weight form the trials used.
Omega 3: Eases stiff joints with regular use and supports heart health. 330 mg EPA and 220 mg DHA per capsule.
Vitamin D3 & K2: Keeps muscles and bones strong; low vitamin D shows up as widespread aches. 2500 IU with K2.
N Acetyl Glucosamine: Supports joint comfort and mobility, and is gentler on the stomach than standard glucosamine.

Common questions
How long does collagen take to work?
Two to three months. The trials that measured skin and joint outcomes ran for around 90 days, so anything shorter is not a fair test.
Does anything on this page treat arthritis?
No. These products carry authorised claims about normal collagen formation, cartilage, muscle and bone. A hot, swollen or red joint, or stiffness lasting more than an hour in the morning, needs a GP.
Marine or bovine collagen?
The difference is source and taste rather than evidence; both are hydrolysed peptides and the trials do not separate them clearly.
