Overview
21st Century VegeSamin 500mg Capsule is a glucosamine supplement from 21st Century, providing 500mg of glucosamine hydrochloride per capsule. What sets VegeSamin apart from most glucosamine products is its source: the glucosamine is derived from corn rather than from the shells of shrimp, crab or other shellfish. This makes it a vegetarian, shellfish-free option for adults who prefer to avoid animal-derived glucosamine.
Glucosamine is an amino sugar that the body naturally produces and uses as a building block for glycosaminoglycans, which are structural components of cartilage and the fluid that lubricates the joints. Glucosamine supplements are commonly taken by adults as nutritional support for joint and cartilage health, particularly in middle age and later life. Research findings on glucosamine have been mixed, with some people reporting benefit and others noticing little change, so it is best viewed as a dietary supplement rather than a replacement for medical care.
VegeSamin is supplied as easy-to-swallow capsules, and the pack listed on DoctorOnCall contains 30 capsules. It is generally taken with meals to help reduce stomach discomfort. Because it is made from a non-shellfish source, it may be a suitable glucosamine option for people who follow a vegetarian diet or who wish to avoid shellfish-derived ingredients, although anyone with allergies should still read the full ingredient list on the label.
Directions for Use
Swallow the capsule whole with a glass of water during or after a meal. Taking glucosamine with food may help reduce stomach discomfort. Follow the serving size on the product label or as advised by your doctor or pharmacist, and do not exceed the recommended amount.
Dosage
Adults: 1 to 2 capsules daily with meals (500mg to 1,000mg of glucosamine hydrochloride per day), or as directed by your doctor or pharmacist. Please follow the serving instructions printed on the product label.
This product is intended for adults. Glucosamine is usually taken consistently over several weeks, as any effect is not immediate. Do not exceed the recommended daily intake, and if you miss a dose, simply continue with your next usual dose.
Storage Instructions
Store in a cool, dry place away from direct sunlight, heat and moisture. Keep the bottle tightly closed after use and keep out of reach of children. Please also follow any storage instructions printed on the product label.
