There is much to be said about the different Guaifenesins, and it can be a bit confusing, here is some info on the Guaifenesin that is appropriate for the protocol:
FA: Fast Acting. Also known as Short Acting and Immediate Release. (the kind you can take later on to speed things along, but not sufficient by itself for the protocol.)
LA: Long Acting. Also known as Extended Release (the kind you need to clear on the protocol.)
ok, here are the different brands that work for the Guaifenesin Protocol:
MDR/Fibro Pharmacy Guai (Marina Del Ray Guaifenesin) is in capsules and has Long Acting/Extended Release and also the Fast Acting/ Immediate Release ones. This is your best option for guaifenesin right now unless you live in Canada. It is a good one to start on, as it is reliable and been used for a long long time, They have different kids of capsules, and right now I believe they are using the vegetarian caps, which are easier on our tummies :). Click here to go to purchase at MDR.
Generic guai (Updated 9/18/17) (found at pharmacies all over like in Walmart and Walgreens) is back in stores and the new ones do not have blue dye! YAY! Make sure you only buy the ones without blue dye since Dr St Amand has seen stalling in clearing from blue dye. Also, They do have some FA/IR in it which makes us need to dose this guai 3x a day instead of the 2x a day like the MDR/FibroPharmacy guai. (Used to be made by Perrigo, but not the new generic ones) Always look for 12 hour and Extended Release on the bottle.
Guai Aid (updated 9/19/17) Guai aid has had a bad rap for alot of years for being all FA/IR. A trusted source has contacted the company and tested out their product for 6 months on more than one person, being mapped by a trained, reliable mapper, and found the 300mg and 600mg Long Acting enough for the protocol. They don’t last the full 12 hours, so need to dose 3x a day instead of 2x a day. Much like generic guai. Make sure you buy the 300mg and 600mg as these are the LA ones. The 200mg and 400mg are only FA, do not use these for the protocol. This is WONDERFUL news for everyone, as this is the cheapest alternative out there.
**Please note that Dr St Amand is now suggesting Mucinex is not appropriate for the protocol due to the blue dye.
Estevan Guai is AWESOME but only available for those living in Canada. Long Acting Pure Guaifenesin through Estevan Pharmacy, Victoria BC. Speak with Kyle. Phone number: 1 250 598 2517 He is very kind but will have a lot of questions, he will treat you like his own patient. He sells both LA and FA in many sizes 🙂 He does ask for a prescription, so keep that in mind.
German Guaifenesin MC is a bit of a mystery since we can’t get a straight answer from the pharmacist who makes them. But some in Germany are using this guaifenesin successfully when dosed 3x a day instead of the twice a day as the MDR/Fibro Pharmacy guaifenesin. German LA guai has Guaifenesin MC as the name. MC stands for methylcellulose which causes the guai to become Long Acting . It comes in 150mg MC, 300mg MC, 450mg MC. If it does not have MC beside the name, then it is Fast Acting and not good for the protocol. This is the website for ordering the Guaifenesin MC: http://husarenshop.de/
The trouble is mostly at the beginning, the first couple months of titrating your dose to find your clearing dose. Click for: Steps to Find Your Clearing Dose.
In the end, everyone is so different and will respond differently to the different brands.
So, any more thoughts on these different guai’s?
