Multiple Chemical Sensitivity (MCS)

AKA Idiopathic Environmental Intolerance (IEI), Environmental Sensitivity/Illness

This syndrome – collection of symptoms – is triggered by a wide range of chemicals that are primarily, but not exclusively man-made. Reactions occur at low-level chemical exposures that do not trigger reactions in all people exposed.

Characteristics of MCS

Characteristic of multiple chemical sensitivity (MCS) is chronicity, symptoms are consistently triggered at a low-grade exposure to chemicals that is innocuous to most people, symptoms are triggered by more than one type of chemical and the symptoms are diverse and involve more than one body system (i.e. respiratory tract and digestive system).

Symptoms of MCS

Symptoms of multiple chemical senstivity can include difficulty breathing, irritation/pain of the eyes, sinuses, throat and lungs, abdominal pain, digestive problems (nausea, indigestion/heartburn, vomiting, diarrhea), skin irritation, headaches, joint and muscle aches and pains, paresthesias (abnormal neurolocal sensations such as pins and needles, burning, and tingling), extreme fatigue, anxiety, impaired sleep, wakes tired, visual disturbances, inability to focus, impaired memory, and abnormally acute sense of smell and sensitivity to smells.

Triggers for MCS

Chemicals that can trigger reactions include cleaning products, scented products (perfumes, colognes, air fresheners, cosmetics, soaps, shampoos, conditioners), engine exhaust, plastics, pesticides, herbicides, fungicides, chlorine, synthetic fabrics, petroleum products, paint and stain, mold, new carpet, new furniture, fresh ink print, dry cleaning residue on clothing, wood smoke, tobacco smoke, and artificial colors and flavors.

Symptoms of MCS


Symptoms can include difficulty breathing, irritation of the eyes, sinuses, throat and lungs, abdominal pain, digestive problems, skin irritation, headaches, joint and muscle aches and pains, and more.

Learn how chemical intolerance to natural and man-made chemical compounds in your food and environment contributes to your multiple chemical sensitivity. Learn what you can do to get clarity and freedom from the shackles of living with MCS. Our six part email program will help you.

Distilling Down Multiple Chemical Sensitivity

This is an extremely diverse list of chemical triggers for MCS and seems to deny sense. However, as a whole these compounds fall within a few families of compounds that include sulfites, aldehydes, phenols, biogenic amines, and histamine. Impaired metabolism of these compounds appears to be the underlying issue for people who meet the criteria for MCS and why they experience reactions to chemicals at concentrations that do not trigger reactions in others.

Vinami for MCS

Vinami is specifically designed and formulated to support improved metabolism of these compounds. A six to eight week trial of Vinami will determine how useful it is to improve your tolerance to chemical compounds from you food and environment – both natural and man-made.

Ruling Out Illness

Multiple chemical sensitivity can be confused for illnesses that need the attention of a physician. Possible conditions that might mimic MCS are depression, anxiety and somatoform disorders, neurological conditions that affect sensory processing of odors.
