So I decided to actually test the purity of my NSI (Vita Cost) MSM capsules. I had an old bottle of Puritan's Pride MSM Powder to compare it to.
Pure MSM should first sink to the bottom of the glass of water and then dissolve completely within a few minutes.
My Puritan's Pride MSM passed the test with flying colors. It sank to the bottom and then dissolved completely.
As for the NSI capsules... all I have to say is that I will never order a Vita Cost brand product from Vita Cost again. All contents of the capsule floated on the top of the water and did not dissolve at all as you can see.
As far as the Puritan's Pride MSM I just have one question about it... Why doesn't it have that sulfur smell? It has no sent to it really at all and I think that is why I got skeptical and stopped taking it. What do you guys think. Are there any brands that have a proven quality that anyone can recommend to me. Please and thank you. 1
