, we declare the ‘active’ glucosamine weight, most popular sulphate form of glucosamine, a true a one-a-day formula & easy to swallow tablets, sensible pot size for maximum freshnessnature’s best glucosamine provides 1500mg of high quality glucosamine sulphate 2kcl in each tablet providing a whopping 1131mg of ‘active’ glucosamine sulphate per tablet. this is the same strength glucosamine as that offered by other companies however other companies show the compound weight of 1500mg without owning up to the actual ‘active’ weight which we think is misleading.to effectively stabilise the formula we use potassium chloride (and not a sodium salt) as part of the overall compound which is widely regarded as the most effective method of glucosamine stabilisation. however the level of potassium in the product is virtually insignificant compared to the ideal daily intake of 3000mg. nature's best 1500mg tablets have been specially made to ensure the same easy absorption as our 2kcl 1000mg tablets & coated for easy swallowing. we’ve also chosen to supply the tablets in a sensible pot size of 180 tablets rather than 360 tablets for maximum freshness.our glucosamine sulphate 1500mg has gained a large fan-base due to its optimum strength & the convenience that comes from a one tablet a day. it makes the ideal choice for anyone wishing to take fewer tablets daily but still achieve high glucosamine levels. popular with active individuals. genuinely 100% made & tested in the uk to gmp standards.
