I've been using Piping Rock brand because I was ordering 10 bottles at a time for 5 something dollars a bottle and 5 dollars shipping. Theirs is a fast release (coconut oil extract) formula.
The original brand of monolaurin is called Lauricidin (probably named after lauric acid, the main effective compound found in coconut oil). Instead of capsules this stuff is formulated into coated pelets that are supposed to get past your digestive system. I've never tried them.
Instead of lauricidin I ordered a cheaper brand called Ultimate Monolaurin which should be here in about a day or so. The price is comparable to the piping rock brand but you have to order a 21 oz tub to get that price.
The reason I am trying the pellets is for a more sustained release. In the past I've only used monolaurin when I was feeling bad and it's always kicked the crap out of whatever I had after a few doses but now I'm aiming at possible viruses that live in the joints near the bones which are much deeper, so maybe a slower release for a more sustained dose might work better. I've always been afraid that taking it all the time might reduce it's effectiveness and keep it from working, similar to the way antibiotics kill the original form of pathogen and allow it to mutate till they no longer work.. Hopefully this is not the case. I was a caregiver to a woman who got prescribed antibiotics like they were candy. She died from an infection that they would no longer control. I haven't been able to find any information about this happening with monolaurin but that doesn't mean it can't happen!
So far the higher doses of monolaurin seem to be working for my backaches and joint pain...
Hope this helps!
