Glucosamine Supplements

Glucosamine supplements are taken by many people with joint discomfort, often combined with chondroitin or turmeric, and they come as caplets, tablets, capsules and powders. Research results are mixed, with some people reporting relief and others none, so the first decision is whether to try it, ideally after talking to a doctor, especially if you have diabetes, a shellfish allergy or take blood thinners.

Form and dose are the next questions. Glucosamine sulfate and glucosamine hydrochloride are the common forms, and many studies used a set daily amount of glucosamine sulfate. Compare the amount per serving and how many pills make up the daily dose, since some products need several large tablets a day.

Source matters for allergies. Most glucosamine comes from shellfish shells, so people with shellfish allergies should look for products from non shellfish sources, which are labelled as such.

Before buying, check the glucosamine form, the daily dose, the other ingredients, the tablet size and the number of servings. Give any joint supplement several weeks before judging it, and stop if you notice side effects. Liquid and powder forms suit people who find large tablets hard to swallow, and chewable versions exist for some products. Combination formulas cost more, so check whether you actually want the added ingredients. Pets have their own joint supplements, which should not be swapped with human products. Store tablets in a cool, dry place with the lid closed.
