Cost of the Marshall Protocol

Related article: Insurance coverage

One of the prerequisites for starting on the Marshall Protocol (MP), a treatment that generally lasts for many years, is the money and/or insurance necessary to pay for certain basic expenses. These expenses include clinic visits, laboratory tests, medications, and special protective sunglasses. Some of these costs are fully or partially covered by insurance. Patients can check their coverage before agreeing to a visit, test or medication so that they are aware of the potential cost. In the United States, insurance coverage varies widely. Patients usually obtain full insurance coverage for the Protocol.
In Australia, cost is modest for those with a pension or Health Benefit card, but the doctor must be prepared to make a case as to why a particular patient requires frequent dosing of Olmesartan.

Visits to a physician

To do the MP, patients require a licensed physician, whose responsibility it is to monitor progress and prescribe the necessary medications. This cost of the physician depends on a couple factors:

  • if the physician is fully or partially covered by insurance
  • the frequency of visits

Some patients have asked their physicians if they could cut costs by minimizing clinic visits. Some physicians allow patients to keep in touch via e-mail or phone.

Laboratory tests

While laboratory tests may be useful in monitoring progress and immunopathology, there is only one laboratory test an MP patient absolutely needs to get with any regularity.

The only laboratory test that is necessary in all cases is the test for 25-D. The 25-D test is important because it suggests how much the immune system is being suppressed by vitamin D consumption. Patients can forgo the 1,25-D test, which is the more expensive of the two tests, if one's physician does not require it.

The 25-D test should be done prior to starting the MP and once or twice a year thereafter. The 1,25-D test only needs to be done prior to the start of the MP, if at all.

Usually, the D-Metabolites tests are covered by insurance without question when using the appropriate codes. For patients wanting to test their 25-D independently, home test kits are available.

Other routine and disease-specific laboratory tests, such as chest x-rays, may be needed as determined by a patient's physician.

Some doctors have been known to order an expensive panel of tests routinely on new patients. This is not part of the MP and you should carefully question the need for any test before you agree to it. Seek advice on the forum before you make any decision if the expense concerns you.


MP patients who experience any light sensitivity must protect their eyes using special sunglasses. While there are a couple of more stylish and expensive options, two pairs of basic NoIR sunglassses (10% and 2%) retail for around $40 each.


There is some financial help available for buying Benicar and other prescription medications. Benicar's own label, Daiichi Sankyo, sponsors one called the Open Care Program.

Olmesartan (Benicar)

Four (or more) times every day, MP patients take 40mg doses of Olmesartan medoxomil (Benicar), a medication for which there is no substitute. Patients can use the generic form (olmesartan medoxomil) or the brand name (Benicar). For patients who must buy olmesartan out of pocket, online discount pharmacies sell a month's worth of generic olmesartan for around $80 or less.

Patients who have a medication benefit to their insurance coverage, including Medicare and Medicaid, may have to file an appeal to obtain full coverage of the recommended dose of olmesartan. If any problems are encountered, patients usually win on appeal of their claims, unless their insurance policy specifically states that off-label use of medications is prohibited.


Low-dose antibiotics may be optionally used during the MP. The most commonly used antibiotic is minocycline, which is available in low-cost generic formulations. Low-doses of a few other antibiotics may be optionally added. The cost of these optional antibiotics are generally reasonable, with some regional exceptions.
