The big pro to this is that you get all three of these supplements in strong doses, in one liquid form which makes it much easier to take than most of the giant pills on the market.
I have searched across the internet and have not found any other supplier that makes a liquid formulation with these strong doses, and as somebody who is actively working on knee joint problems, taking this type of supplement is crucial.
The con is that the flavor is rather medicinal and still a bit hard to get down. I recommend taking two swigs instead of one large one because it really is a mouthful.
I wish that they made the glucosamine, chondroitin, MSM in an orange flavor like their magnesium supplement, because this tastes nothing like blueberries.
I still highly recommend this for anyone who is needing a really good joint supplement and doesn't want to take 6 to 8 pills everyday.
