3. Interstitial Cystitis

Based on the proven benefit of DMSO in the cases, preliminary research has been undertaken with MSM. It

appears that MSM may also be of useful in the treatment of interstitial cystitis, but further investigation is necessary

to substantiate this application.19

Dosage and Standardized Grade

When administered as a single treatment agent a dose as low as 250 mg per day has been shown to be ef ective.

Other studies have used doses as high as 2,000-6,000 mg per day. As indicated by Drs Jacob and Lawrence, it is

likely best to use MSM in conjunction with glucosamine sulfate, and possibly other natural anti-inflammatory agents, to

assist in the management of arthritis and other musculoskeletal disorders. 19, 20, 21

Adverse Side Effects, Toxicity and Contraindications

There are naturally occurring concentrations of MSM in the human system of approximately 0.2–0.25 ppm, presumably

originating from food. 22 The LD-50 in rats has been determined in excess of 20g/kg BM/d, indicating that MSM is an

extremely non-toxic compound. 23 Other animal studies of toxicity have provided similar evidence, reporting no or very

low toxicity at extremely high doses. 23 In humans, MSM has been established as a safe supplement. At high doses (2-

8 gms per day), some gastric upset or diarrhea may occur. 24,25

Drug-Nutrient Interactions

There are no well-known drug-nutrient interactions at this time in regards to MSM supplementation. 26

Other Frontiers Of MSM Research Include Cancer Prevention

In animal studies MSM supplementation has been shown to prevent and delay the development of colon and breast

cancer in rats treated with known chemical carcinogens. 13, 28 This effect may be due to its ability to support methionine

levels (helping to prevent hypomethylation of DNA, which results in fragile chromosomal linkages leading to mutations)

or related more to its anti-proliferative action. 29,30 How this applies to humans at this time is not known.

Pregnancy and Lactation

During pregnancy and lactation, the only supplements that are considered safe include standard prenatal

vitamin and mineral supplements. All other supplements or dose alterations may pose a threat to the

developing fetus and there is generally insuf icient evidence at this time to determine an absolute level of

safety for most dietary supplements other than a prenatal supplement. Any supplementation practices

beyond a prenatal supplement should involve the cooperation of the at ending physician (e.g., magnesium

and the treatment of preeclampsia.)

N-Acetylcysteine (NAC)

General Features

N-Acetylcysteine is a modified form of the amino acid cysteine, which when taken as a supplement can help the body

increase its glutathione stores – an important antioxidant and detoxification agent. In conditions of heightened

oxidative stress, HIV infection and certain chemical toxicities that damage the liver, the supplementation of N-

Acetylcysteine can be used to elevate or re-establish more optimal levels of liver and blood glutathione.

In liver detoxification the most important antioxidant for neutralizing the free radicals produced as Phase I by products

is glutathione.

Glutathione is a tripeptide composed of three amino acids, namely cysteine, glutamic acid and glycine. Glutathione

also provides a detoxification role in Phase I detoxification by acting as a conjugating agent. Conjugation reactions

either neutralize toxins produced by Phase I detoxification enzymes and/or

make the toxin more easily excreted through the urine or bile.

When high levels of toxin exposure results in extensive free radical intermediate build up from Phase I detoxification

processes, glutathione is rapidly used up and a glutathione deficiency state may occur.

Glutathione conjugation is extremely useful to convert fat-soluble toxins into a water-soluble form, allowing more

ef ective excretion via the kidneys.

Certain conditions that increase oxidative stress also more rapidly use up glutathione in its antioxidant function. In turn

this can lead to glutathione deficiency and a worsening of the patient’s condition. Conditions that are linked to

glutathione deficiency include HIV infection, idiopathic pulmonary fibrosis and adult respiratory distress syndrome.

Glutathione supplements are not well absorbed, however supplementation with vitamin C (500-3,000 mg per day) and

Vitamin E (400 – 800 i.u. per day) have been shown to raise blood and liver glutathione levels in various studies.

In patients with AIDS or HIV infection, supplementation with N-Acetylcysteine has been shown to be a very ef ective

way to boost glutathione levels.1
