Chemical Cocktail or Health Product?

Natural health products are safe. You can go into a health food store and try something from the shelf, and be sure that it isn’t going to harm you.

The downfall of having supplements readily available, is that many people think that they can self-prescribe correctly.

I often hear people say that a “natural health product didn’t work for me.” With further investigation I find out that they did not take the product at the right time or in the correct dosage or form for their body type.

Many people believe that since these products are so accessible and don’t require a prescription, they must be simple to use. This couldn’t be further from the truth.

I have spent countless hours studying which supplements are the best. Also, when I put a personalized nutritional protocol together for a client, it takes me about ten hours of research before I make a single recommendation of what to take.

One of the most popular supplements on the market is the multi-vitamin Centrum. What many people don’t realize is that this multi-vitamin is probably doing more harm than good.

A Few Centrum Facts

  • Centrum is a product produced by the company Pfizer, one of the largest pharmaceutical companies in the world.
  • The dosages of most of the nutrients in Centrum are negligible and not even close to therapeutic levels.
  • The forms that the nutrients are provided in are the cheapest and the least absorbable forms.
  • Supplements that come in tablet form are often hard to digest and contain binders and fillers (more on this below).
  • Water-soluble nutrients (vitamin C and the B-vitamins) are either used or excreted within about 4 hours. Thus, a one-a-day multi is completely useless and a sure sign that it is of poor quality.

The Ingredients In Centrum

Calcium Carbonate This is the least absorbable forms of calcium on the market. A very small percentage is actually absorbed.

Ferrous Fumarate This form of iron often causes constipation.

Pregelatinized Corn Starch This is used as a binder to hold all of the ingredients together. It most likely a genetically modified corn which presents a number of problems for sensitive people.(1)

DL-Alpha Tocopherol This is vitamin E and they are using two forms. The “D” form which is natural and the “L” Form which is synthetic. The “L”  form is used to “water-down” the more expensive and bioactive “D” form.

BHT Butylated hydroxyanisole has been shown to be toxic to the liver, thyroid, kidney, and lungs, and can affect blood coagulation.(2) BHT can act as a tumour promoter.(3)

FD&C Yellow No. 6 Aluminum Lake Why is there food colouring in a health supplement?

Gelatin Vegetarians watch out!

Hydrogenated Palm Oil Hydrogenating any oil turns the oil rancid and makes it into a strong free radical. Free radicals promote cancer and heart disease.

Nickelous Sulfate and Tin I have never come across any nutrition book discussing a nickel or tin deficiency. Have you? We most likely don’t need to supplement it.

Sodium Benzoate A preservative that may cause organ toxicity.(4)

Talc Has been shown to cause cancer. (5,6,7)

Sodium Aluminosilicate Used as a food additive for its anti-caking effect.

One of my rules when shopping for nutritional supplements is to never buy supplements in a drug store.

Centrum is only available in drug stores and is advertised as the “#1-recommended doctor multivitamin” (doctors receive no more than 40 hours of nutrition training).

When it comes to a multi-vitamin I recommend going to a health food store and talking to an employee about a good-quality multi-vitamin.

Tips For Choosing A Multi-vitamin

  • Look for a multi with a dosage of at least 2-3 capsules per day.
  • You get what you pay for: The more expensive the multi is, the better the product.
  • Don’t buy it if it says “doctor-recommended” on the label or if a pharmaceutical company distributes it.
  • Consult with a clinical nutritionist to determine the right multi-vitamin for you.
