Yumove is an increasingly popular joint supplement from Lintbells - a company with a great reputation for good products.
This supplement comes in handy tablet form, and seems to taste good, so should go down easily.
Its glucosamine is sourced from green-lipped mussels, a great natural source. Yumove also includes chrondrotin.
Unfortunately, it doesn't contain MSM (methylsulphonylmethane) which is a really effective anti-inflammatory found in other supplements and which can alleviate pain suffered by dogs with joint issues.
Its concentration levels make it less cost-effective than Riaflex - see table below.
Nevertheless, Yumove is developing a strong reputation as an effective joint supplement, so is well worth giving a try.
