Health Perception Glucosamine Sulphate has a lower dosage of 750mg glucosamine sulphate so you can choose whether you would like to take a higher or lower dosage e.g. one or two tablet depending on your preferences. By taking one in the morning and one in the afternoon youll give your body the chance to absorb the glucosamine over time. Weve also added 2mg of manganese and 55mg of vitamin C which aids absorption of manganese. Manganese is essential for the formation of certain enzymes, one of which is superoxide dismutase, a powerful antioxidant enzyme that neutralises potentially damaging free radicals. If that wasnt enough weve also added 80mg of calcium to help keep your bones strong!GlucuOsamine is an amino sugar which is produced naturally by the body from glucose and L-Glutamine.To reinforce the fact that Health Perception glucosamine is manufactured to the highest pharmaceeutical standards,it is the only glucosamine to have been chosen for use in a leading British hospital trial.
