I was looking to try out glucosamine in case my intermittant knee soreness was due to cartilage wear and tear. (I'm ≈45) But the lady at the shop convinced me to try out the rose-hips powder supplement described in the following article.

Apprently the makers have a patented process that preserves the key ingredient, a "sugary fatty acid called GOPO", that is anti-inflammatory and shows some indications of promoting cartilage regeneration.

According the the lady at the shop, her customers swear by it, including middle aged people who want to be able to work out hard. But according to my doctor wife, it's only for old ladies with arthritis

Anyone have experience of this supplement? I'm about to give it a go for two months.
