"100% chondroitin sulphate powder, pure without additives Origin:. Beef" and not from shells of crabs, shrimps, lobsters
Natura Vita chondroitin powder, pure 100g (Personal Care) 5
The only product I could find on the fast, which consists of beef, instead of shells of crabs, prawns, lobsters and mussels, on which can be allergic to a lot more likely. In addition, this is the good sulphate form that works in studies at all (other forms bring partly no improvement). And this is as a powder and without any additives. So great.
It is recommended this be given in combination with glucosamine sulfate and sulfur (MSM). This can and should perhaps silica (including for connective tissue), gelatin take (eg for cartilage) and manganese (eg for cartilage, bone).
Many nutrients are related, such as iron deficiency, although it takes iron tablets if the copper is missing.
