The compound

What Glucosamine Sulfate Potassium Chloride Is

Glucosamine is an amino sugar and, as the NIH LiverTox database describes it, a natural component of cartilage. In supplements it is sold in several salt forms. "Glucosamine sulfate potassium chloride" is glucosamine sulfate combined with potassium chloride, and it has its own monograph under that name in the United States Pharmacopeia–National Formulary. The "D-" in front of the name on the VapoCept label refers to the natural form of the sugar.

How it is made

LiverTox notes that glucosamine in commercial supplements is usually prepared from the exoskeletons of shellfish or from fermentation of grain.

What the label tells you

The form and the amount. The VapoCept label lists "D-Glucosamine Sulfate Potassium Chloride" at 250 mg and does not say which source was used.

If you avoid shellfish

Because the source is not on the label, ask the distributor before ordering: contact@customercs.com or +1 (507) 448-8190.

Safety

Glucosamine Safety: What NIH LiverTox Says

LiverTox, the NIH database on supplements, herbs and medicines and the liver, describes the side effects of glucosamine as uncommon and mild, such as abdominal discomfort, nausea, fatigue and headache. It notes that glucosamine has been mentioned in isolated case reports, that the role of glucosamine itself in those reports has not been shown, and that liver injury due to glucosamine must be very rare if it occurs at all.

The VapoCept label adds its own caution for pregnant or nursing mothers, under-18s and anyone with a known medical condition: consult a physician first. If you take medicine, check with a doctor first.
