Top 5 Mistakes Patients Make That Reduce Supplement Effectiveness

By G. Douglas Andersen, DC, DACBSP, CCN

There are many reasons why nutritional supplements are sometimes ineffective. In some cases, it is simply due to a bad product that does not meet the label claims or is produced with poor quality control.

It can also be from exposure to temperature or moisture at any step from the manufacturer to the consumer. However, these are not the most common reasons why nutritional supplements fail to provide the desired results. In my practice, the five most common reasons supplements do not yield the desired effects are caused by how and why they are used.

#5: Micro-Overdosing

Micro-overdosing is not a pathologic overdose. It is the mistake of taking the correct daily allowance of products that require divided dosing in a single serving. For example, instead of taking one pill three times a day as directed, a person takes three pills once a day. What makes this mistake so common is that many popular supplements (such fish oil and glucosamine) can be taken all at once. But for others, such as calcium, taking the full daily requirement all at once exceeds the dose that can be digested at one time.

Unintended underdosing happens when a person unknowingly takes less pills than they should. It is most often seen with products whose supplement facts are for multiple pills. A common scenario would be a woman who is told she needs a stronger multivitamin than the one-pill-a-day product she uses. She finds a better brand and takes one a day, never realizing it's a four-pill-a-day product – meaning the ¼ dose of the new product may be less than the low-potency product it replaced.

#3: Meal Mistakes

Some supplements require a meal for absorption, while others have better uptake between meals. Depending on the product and the person's unique GI tract, this mistake can result in a partial to total loss of supplement effectiveness.

#2: Inconsistent Use

Inconsistent use can also be described as frequency underdosing. This error occurs in one of two ways – missing days (e.g., a 30-day bottle takes 60 days to finish) or replacement delays (e.g., repurchasing the product 14 days after running out).

#1: Taking Unnecessary Supplements

The most common reason supplements don't work in a particular patient is because they aren't needed. Whenever I do a nutritional consultation, I have the patient bring in every supplement they own (or e-mail the list to me in the case of phone appointments) and determine why each product was purchased. In my experience, I have found that friends, co-workers, family members, acquaintances and the media (including advertising) are the primary sources of advice on nutritional supplements for many people. In most cases they are very well-meaning, but equally unqualified to give this type of guidance.

I ask a simple, diplomatic question in these situations: "How many questions did the person who recommended the dietary supplement ask you about your diet?"
