linguisil msm is just normal msm with a botanical additive which means they can hike up the price. all msm will be equally bio available for you so go for something bulk and get a great price. as i've been led to understand none of it is refined from plants, all of it is chemically produced as the cost would be far to prohibitive
your location would help. in the uk search a1 msm in google. if australia try bulk msm in google. do some research maybe
emery that was my point, no brand is better than any other. it basically all comes from a few different chemical companies producing it then others package and sell it on. look for a good price, dont worry bout the brand.
