How to Choose The Right Nutritional Supplements

Robert Zembroski, DC, DACNB, MS

The standard American diet consists of foods which are high in calories and low in nutrient content. Current research tells us that this unhealthful way of eating is also the main reason behind most of the illnesses we all suffer from.

This being said, nutritional supplements, such as vitamins, minerals, herbs, and enzymes, provide a portion of the daily nutritional needs—filling in the pot holes—for people who could become ill due to lack of proper nutrition on top of stressful lifestyles.

Can’t decide what nutritional supplements to take? Overwhelmed with what to take and why? Not sure if you should buy a powder, capsule, tablet, or chewable?

Undoubtedly, there is a daunting number of nutritional supplements to consider, as well as too many companies to choose from. When considering nutritional supplements, it can also be difficult to understand what works and what doesn’t. It is wise to exercise caution when buying nutritional supplements you know little about or have never tried.

When considering nutritional support, there are some things you should keep in mind:

  • Choose a company which complies with good manufacturing practice (GMP), pharmaceutical-grade production and ingredients, as well as quality-control measures.
  • Look for supplements that are tested and analyzed for their effectiveness, purity and potency.
  • Get some information about supplements. You should know that certain vitamins work together, i.e., Vitamin C and Vitamin E
  • Be aware that some medications and/or medical conditions do not pair well with certain supplements. For example, St.John’s Wort (an herbal supplement) should not be taken with antidepressant medication. Feel free to call us to find out which supplement can affect the intended use of the medication you take, and to make sure there are no contraindications.
  • Consider your specific needs. Are you looking for a multivitamin, a specialty product, or help with a specific health condition?
  • As more and more brands get into the market, it’s up to you to look for the best quality money can buy. Look no further; the DCFM has chosen supplement manufacturers that produce scientifically researched, doctor-formulated, high-quality nutritional products that have been shown to be very effective for their intended use.

If you want to take a health supplement because of a specific condition, you may want to choose a specialized product. Both companies have supplements that are formulated to address certain issues.

You can also call us with specific questions on general nutritional support, including which products would be best suited for you.
