How to increase cartilage in joints naturally?

What cannot go up: adult cartilage and the reason no natural method regrows it

How to increase cartilage in joints naturally is a question with a false premise and a useful answer hidden beneath it, and the honest page deals with the premise first, because a reader who spends a year trying to increase cartilage has spent a year on the one thing that cannot happen while three things that can were available. Adult articular cartilage, the smooth surface on the ends of the bones in a joint, does not regrow. It is avascular, so no blood brings repair cells or nutrients to a damaged area beyond what diffuses in from the joint fluid; it has no nerve supply, so damage is felt only when the bone beneath or the joint lining is involved; and it is populated by sparse chondrocytes locked in their matrix, which maintain the cartilage around them and cannot migrate to fill a defect or divide to replace lost tissue at any meaningful rate, the cartilage biology literature's reason that a cartilage injury in the twenties is still there in the forties and that osteoarthritis, once cartilage is lost, does not reverse. Nothing natural changes that, and nothing in a tub does either: the trials of glucosamine, chondroitin, collagen hydrolysate, vitamin D and fish oil in knee osteoarthritis that measured cartilage by MRI or joint space by X-ray found no meaningful slowing of loss and no regrowth against placebo, whatever they found on symptom scores, so no oral supplement has increased cartilage in a human joint and a reader who is told one does is being told something no imaging has ever shown. Cartilage repair, where it exists, is a surgical field, cell implants and grafts for focal defects in the right knees, and the fact that operating theatres exist for it is the plainest evidence that no natural method or capsule regrows the tissue. That is the premise dealt with: the amount of cartilage in an adult joint can be kept and cannot be increased, and the question becomes what can be increased that the joint depends on, which turns out to be three things and all of them natural.

What can go up: the cartilage's quality, the muscle around the joint, and the room the joint has

The first thing that can go up is the quality of the cartilage that remains, and it goes up with load. Cartilage is mechanosensitive: its chondrocytes respond to the cyclic compression of use by maintaining the matrix around them, and the matrix's glycosaminoglycans, the long charged molecules that hold water and give cartilage the pressurised stiffness that lets it bear load, increase in content when the joint is loaded regularly within tolerance and fall when it is not, the contrast-enhanced MRI studies showing higher glycosaminoglycan content in the knee cartilage of adults who took up moderate regular exercise and thinning, softer cartilage in the immobilised. So the natural way to improve cartilage is to use the joint, walking, cycling, swimming, resistance work through a pain-free range, progressively and often, which does not add cartilage but makes the cartilage that is there wetter, stiffer and better at its job, and which is why the clinical guidance for osteoarthritis puts exercise first and rest nowhere. The second thing that can go up is the muscle around the joint. The quadriceps, hamstrings and glutes at the knee, the glutes and deep hip muscles at the hip, the rotator cuff at the shoulder, share the load the joint takes and control how it lands, so a stronger, better-coordinated muscle envelope means less load reaching the cartilage at each step and less of the shearing that wears it, and muscle is built by progressive resistance training over months, the most natural and best-evidenced joint intervention a lifter owns. The third thing that can go up is the room the joint has, by which the honest page means the load taken off it: each kilogram of body weight adds around four kilograms of force across the knee with every step, so a five-kilogram loss takes twenty kilograms off each stride, and weight loss in overweight adults with knee osteoarthritis reduces pain and improves function in proportion to the weight lost, which is why weight management is first-line in the guidance beside exercise. Three natural increases, then, none of them cartilage and all of them the things cartilage needs: better matrix through loading, more muscle through training, less load through weight. Collagen's place at the end is honest and small: the joint comfort trials at around ten grams a day over months measured how a joint felt under load and found modest gains, not cartilage, and the register's cartilage sentence belongs to vitamin C, which contributes to normal collagen formation for the normal function of cartilage, the maintenance of what is there rather than the increase of it. The worked example is stated on those terms: two capsules, 1200mg hydrolysed type 1 marine collagen with 12mg vitamin C plus zinc, 120 for £16.99 at 28p a day, lab tested and UK made, below the joint research dose, taken for vitamin C's cartilage sentence, for how the joint feels and not for what it is made of. How to increase cartilage in joints naturally: you cannot, and you can increase everything around it that decides how long it lasts.
