Safe and Effective Dietary Supplements – Online Reference Guide

If you take supplements or know some one who does, please continue reading. This is worth 30 seconds of your time, I promise.

For over 22 years, I’ve been working to positively impact the lives of others by sharing what I’ve learned, experienced and researched. Part of this mission was putting my Master’s in Nutritional Sciences to good use in combination with my years of experience as a dietary supplement counselor to investigate the safety and efficacy (effectiveness) of dietary supplements as well as those shown to be quality products by analyzing various available and reliable resources (scientific journals) to create an avenue for people to learn about what products are Tested and True

The knowledge below will help you save money and avoid getting ripped off when it comes to investing in supplements.

What You Need to Know About Supplements

With the passing of the Dietary Supplement Health and Safety Act in 1994, the definition of supplements changed and the industry exploded. At the same time, the supplement industry’s regulation became limited and many people were adversely affected by supplements. In response, the FDA issued a statement in 1998,

“We, as consumers, along with manufacturers, are responsible for the safety and efficacy of dietary supplements.” 

This allowed supplement businesses to grow. It also meant 2 things…

1. Consumer safety and protection was left to manufacturers to meet “Good Manufacturing Practices.”

2. Consumers had to do research to find safe and effective supplements

To help consumers save time and money, and help health care practitioners who take and recommend supplements, I consolidated several years of research to put together a research-based reference guide to find Tested and True supplements below. 

What is a Tested and True Supplement?

Tested (safe) and True (effective) simply means a product passed independent testing, meaning that the product contents are consistent with the manufacturer’s product label, or the product has been shown to be safe and effective in appropriate doses for certain conditions based on what the manufacturer’s label says about what’s in the bottle.* (Please keep in mind that even the products that were classified as Tested and True can have counter indications with certain medications and it’s best to consult with a physician prior to using any dietary supplement).

With consumer safety in mind, I created a Tested and True  reference guide below, which includes research from, as well as several other reputable sources who set standards for quality and purity, including the United States Pharmacopeia (USP) and the National Sanitation Foundation (NSF).
