Achieve Your Goals Faster

Scientific research overwhelmingly demonstrates that dietary supplements can help people overcome vitamin and mineral insufficiency, improve their quality of life, accelerate how quickly and healthfully they achieve their fitness goals, improve performance, and a lot more.

The appeal of improved health, weight loss, fitness, and performance drives millions of Americans to use dietary supplements as part of their healthy lifestyle.

But why do some people obtain results from taking dietary supplements, while others don’t?

The answer to this question is one of the reasons why dotFIT exists.

Why dotFIT Exists

As a former professional bodybuilder, dotFIT CEO, Neal Spruce has always recognized the important role that dietary supplements play in health, fitness, and performance goals.

Neal has been on a mission for several decades to help people improve their lives and achieve their fitness goals through exercise and proper nutrition, which includes dietary supplements.

But he had a problem very early in his career.

Like many other Americans, he couldn’t find a dietary supplement company that was consistently manufacturing safe, high quality, and scientifically sound products.

The supplement industry was full of exaggerated claims, scams, unfair price gauging, and marketing hype.

It still is.

Protection From Low-Quality and Ineffective Dietary Supplements

Every year, multitudes of Americans unknowingly purchase ineffective or harmful products from a mass-market supplement company.

Exaggerated claims, gimmicky practices, unfair price gauging, inaccurate dosages, and marketing hype from many supplement companies can lead to ineffective supplements and potentially harmful effects.

The most common mass-market offenses:

Low-quality products

In 2019 the Food and Drug Administration inspected 598 supplement manufacturing facilities and issued violations for more than 50% of them.

Inaccuracies between labels and product ingredients

The FDA currently maintains a database of 965 + “hidden ingredients” including steroids, prescription medications and illegal drugs.

Window dressing & nutrient filling

Many companies make formulation decisions for their dietary supplements based upon marketing hype, not scientific research. Adding an ingredient solely because of its hype in the marketplace can lead to products that are ineffective and potentially dangerous.
