Description
Blackmores Glucosamine Sulfate 1500 One-A-Day is a high strength, vanilla flavoured film coated tablet that supplies a full 1.5 g of glucosamine sulfate in a single daily tablet. It is listed on the Australian Register of Therapeutic Goods to help reduce the symptoms of mild osteoarthritis, including mild joint pain, mild joint stiffness and mild joint inflammation, and to help maintain joint mobility and healthy joint cartilage production. It comes as two bottle sizes, 90 tablets and 180 tablets. Both bottles hold the same tablet, so the figures below apply to either pack.
Product Strengths
- One tablet a day supplies glucosamine sulfate 1.5 g, from glucosamine sulfate sodium chloride complex 1.884 g.
- Helps reduce the symptoms of mild osteoarthritis, including mild joint aches and pains, mild joint stiffness and mild joint inflammation or swelling.
- Helps maintain joint mobility and flexibility and supports healthy joint cartilage production.
- The glucosamine is GlucosaGreen, a sustainably sourced, non-GMO glucosamine sulfate rather than a shellfish extract.
- Vanilla flavoured, film coated tablet taken once a day with food.
- Choose 90 tablets or 180 tablets, which is roughly a three month or a six month supply at one tablet a day.
Suitable For / Not Suitable For
Suitable for: Adults who want to reduce the symptoms of mild osteoarthritis and support joint mobility, and who prefer a single daily tablet.
Not suitable for: Anyone with an allergy to the listed ingredients. The tablet contains sulfites, soybean products and galactose, so it does not suit anyone avoiding soy, anyone sensitive to sulfites, or anyone on a galactose restricted diet. It carries approximately 151 mg of sodium per daily dose, which is relevant on a sodium restricted diet. This is an adult dose product and is not intended for children except on the advice of a health professional. If you have a shellfish or seafood allergy, check the pack you receive: Blackmores now states this product uses GlucosaGreen glucosamine, but older packs of this product carried a precaution that the glucosamine was derived from seafood.

Precautions
Glucosamine Sulfate
Why choose glucosamine sulfate?
Glucosamine sulfate is the form behind most of the joint research, and year-long trials linked it to less pain for mild knee aches that have hung around for months. Give it a few months to judge how it suits you.

How the forms compare
Common questions
Is glucosamine sulfate better than glucosamine hydrochloride?
On its own, the sulfate has the stronger record. An analysis of 15 trials put its effect size at 0.44, compared with 0.06 for hydrochloride. But an analysis of individual patient data, independent of industry, found no benefit from either, and said the type of glucosamine made no difference. Hydrochloride gives you more glucosamine per gram.
Is crystalline glucosamine sulfate worth choosing over the regular form?
On the only human comparison we have, no. A crossover study gave 10 healthy adults a single 1,500 mg dose of each. Crystalline glucosamine sulfate showed no significant absorption advantage over the regular form, and the regular form actually came out slightly higher. It's a small pilot study, so it isn't the final word, but it doesn't show an advantage for the crystalline form.
Why does my glucosamine sulfate have a kidney warning?
Most likely because it's the potassium chloride form. Glucosamine sulfate isn't stable on its own, so it's stabilised with potassium chloride or sodium chloride. In Australia, the potassium chloride version must carry a warning for anyone with kidney disease or taking heart or blood pressure medicine, and each dose must contain under 550 mg of potassium chloride.
