What vitamin am I lacking if my joints hurt?

The two patterns that may be a vitamin: where and when they hurt

What vitamin am I lacking if my joints hurt is a question with an assumption built into it, that a lack is the cause, and the honest page tests the assumption rather than picking a vitamin to satisfy it, using the method a clinician uses on the same question, which is to let the joints answer by where and when they hurt, because joint pain has a small number of patterns and only two of them point at a vitamin. The first of the two is the pattern that may be vitamin D, and it is worth describing carefully because it is often not joint pain at all in the strict sense. Vitamin D deficiency, common in the UK through the winter months when the sun is too low to make it in skin, and more common in people with darker skin, those who cover their skin, those who are rarely outdoors and older adults, produces an ache that is widespread rather than confined to particular joints, felt in the bones and the muscles around them, the lower back, the pelvis, the thighs and the ribs, with a proximal weakness that makes stairs and rising from a chair harder, tiredness, and sometimes low mood, and it is worse in late winter and early spring. A reader with that pattern has the one common deficiency that produces musculoskeletal pain and has a reason for a blood test, which a doctor orders; if the level is low, correction at the guidance dose of ten micrograms a day, or a higher short course the doctor chooses, eases the aches over weeks to months if the deficiency was the cause, and the register's sentences, maintenance of normal muscle function and normal bones, describe why. The second pattern is rare and specific: joint pain, often in the knees and ankles, with bleeding or swollen gums, easy bruising, tiny bleeds around hair follicles, wounds that heal slowly and tiredness, in someone on a very restricted diet, with alcohol dependence, an eating disorder or an older person living on little fresh food, is vitamin C deficiency, scurvy, in which the collagen enzymes cannot work and connective tissue fails, with the joint pain coming from bleeding into the joints. It is rare in the UK, it is a doctor's diagnosis from the symptoms and a blood level, and it reverses with vitamin C and a changed diet; a reader who eats any fruit or vegetables in an ordinary week does not have it. Those are the two patterns that may be a vitamin, and a reader whose pain does not match either has, in all likelihood, joints that are lacking nothing and hurting for one of the reasons that follow.

The patterns that are not a vitamin, the vitamins that are not joint pain, and the honest habit

The commonest pattern of joint pain in adults is not a vitamin at all. Weight-bearing joints, the knees, the hips, the base of the thumb and the end joints of the fingers, that ache with use and ease with rest, that stiffen for a few minutes in the morning or after sitting and loosen with movement, that creak and occasionally swell after a long walk, in a reader past forty, is osteoarthritis, the wear pattern, and it is lacking nothing that a capsule supplies: its levers are the strength of the muscles around the joint, body weight, since each kilogram adds several to the knee with every step, and regular movement, which nourishes cartilage, with pain relief from a pharmacist for flares and no vitamin in any guideline for it. The second non-vitamin pattern is the one the honest page most wants a reader to recognise, because time matters: small joints of the hands and feet, the knuckles, the middle finger joints, the balls of the feet, hurting on both sides symmetrically, swollen, and stiff for an hour or more in the morning, with tiredness and sometimes a low fever, is inflammatory arthritis, rheumatoid or one of its relatives, and it is a doctor's assessment early rather than a vitamin's, because the treatments that protect joints from damage work best started soon and because no supplement touches it. A related pattern, joint and tendon pain with a psoriasis rash, nail pitting, back stiffness in the morning or a recent gut or eye inflammation, is the spondyloarthritis family and is the same early assessment. The third non-vitamin pattern is urgent: one joint, often the big toe, the knee or the ankle, suddenly hot, red, swollen and exquisitely tender, is gout, treatable and a doctor's; the same joint in someone who is unwell and feverish is possibly infection and is an emergency, since a septic joint is destroyed in days. Having let the joints answer, the honest page clears the vitamins the shelf names that are not joint pain at all: vitamin B12 deficiency brings tingling, numbness, balance problems and tiredness; iron deficiency brings tiredness, breathlessness and pale skin; magnesium shortfall brings cramps and twitches; none of them hurts a joint, and a reader who buys a joint complex because the shelf lists them has bought the wrong aisle. So most hurting joints are lacking nothing, the two patterns that might be a vitamin are found by their shape and tested by a doctor, and the patterns that are not vitamins have their own routes, strength and weight for wear, early assessment for inflammatory arthritis, urgent assessment for a hot joint. Collagen holds no joint claim in the UK and sits beside the wear pattern as the modest knee osteoarthritis trials describe, questionnaire gains at around 10g over twelve to twenty-four weeks with no cartilage change. The worked example is the habit once the pattern is sorted, stated on its true terms: two capsules, 1200mg hydrolysed type 1 marine collagen with 12mg vitamin C at 15% of its reference value plus zinc, 120 for £16.99 at 28p a day, lab tested and UK made, the vitamin C carrying its collagen formation sentence for cartilage and bones, the collagen below the research band and holding no joint claim. What vitamin am I lacking if my joints hurt: probably none, possibly vitamin D if the ache is everywhere and the season is winter, and the joints themselves will tell you which by where and when.
