My husband has been trying this supplement, he works as a grounds maintenance proper and often complains of aching back or shoulders. Each 1303mg daily serving (2 capsules) contains: 300mg Collagen (Marine), 200mg Glucosamine Sulphate, 200mg Boswellia,150mg MSM, 100mg Chondroitin Sulphate, 100mg Vitamin C, 10mg Zinc, 2mg Manganese, 1mg Copper, 55ug Selenium. Each bottle contains 60 easy to swallow capsules giving you a 30-day supply. Not vegan friendly due to marine collagen, also not suitable for shellfish allergy sufferers. The capsules are easy to swallow and have no aftertaste or effects. At the current selling price the 30 day course will cost around 60pence per day, which is not too bad for a all in one supplement. As with all supplements it will probably take a month or two to seeing any effects.
