Breathe Easier with ProHealth's Guaifenesin FA™

Guaifenesin FA™, 400mg, is an over-the-counter drug that acts as a powerful expectorant by helping loosen and liquefy mucus. Guaifenesin is a common component of many nonprescription cold and cough remedies. It is derived from a tree bark extract called guaiacum, historically used for its expectorant qualities in the Caribbean region and adopted by European explorers in the 1500's.

It is also the primary component of the Guaifenesin Protocol developed by R. Paul St. Amand, MD. The protocol, which addresses conditions such as Fibromyalgia, utilizes guaifenesin to help the body eliminate excess calcium and phosphates. Note Guaifensin FA™ contains no salicylates, sweeteners, flavorings, dyes, soy, yeast, dairy, gluten or corn.

Guaifenesin Mechanism of Action

Guaifenesin works by drawing water into the bronchi - the air passages branching into our lungs. The released water both thins the mucus and lubricates the airway, facilitating the removal of cold and allergy associated mucus from the chest by coughing, and making it easier to breathe.

Guaifenesin is also considered helpful for thinning postnasal drainage from the sinuses and reducing nasal congestion, and so may relieve sinus pressure/ headache. As Dr. Sarah Myhill comments, "Whoever designed the human body needs a black mark for putting in sinuses! They are cavities in the bones of the face with only one entry and exit hole which is easily blocked by catarrh or swollen mucus membranes." When this occurs, less oxygen can enter the sinuses, promoting bacterial overgrowth and causing sinusitis.

Guaifenesin can help to relieve congestion by increasing the clearance of secretions, helping with the mucus membrane's natural job of washing away invading viruses, bacteria, pollen and other potential allergens - "the first level of immune defense."

Patients with chronic obstructive pulmonary disease (COPD) may find guaifenesin's thinning and lubricating action helpful at times when they experience particular difficulty coughing up the thick or sticky mucus that can block their damaged airways.

Similarly, guaifenesin can assist by thinning 'sticky' mucus to help expel inhaled particles that can exacerbate asthma symptoms.

Importantly, whether used to ease the congestion of colds or rhinosinusitis, or to support healthy vocal folds, guaifenesin works best if one drinks plenty of water, as extra fluids increase the flow of water and mucus.

Contains only pure guaifenesin and natural ingredients. No sweeteners, flavorings or dyes. Salicylate, soy and corn free.

I love this product! I get a lot of phlegm buildup in my throat, I think from allergies. I have to clear my throat and cough a lot. This breaks up all the phlegm, and my voice is nice and clear!

Surprisingly, Guaifenesin FA is effective in reducing pain and promoting better sleep. The pure form is much better for those of us who have chemical sensitivities.

I had to change to this guai preparation as you were out of stock of my usual type and I am sure it is giving the same excellent results, not because it's not a good product, but I was advised that you should stick to one guai from the start and keep to it. I am now thi ...[read entire review]

I have had chronic bronchitis off and on for about 5 years. I also have chronic neurological lyme disease, babesia and bartonella. Back in 1998 I was incorrectly diagnosed with fibromyalgia and at that time heard about Guaifenesin. I tried it but it didn't do anything ...[read entire review]
