Highest Quality Ingredients produce the Best Supplements

At Lidtke, we manufacture nutritional supplements that are kind to your body and your soul – using only the richest, cleanest natural ingredients that we test ourselves for impurities.

In everything we do, we strive to restore life and health, and we value and honor those who share our philosophy.

Our mission is to educate, enlighten, and share our knowledge base with everyone in our community, and we encourage all of our customers to do the same.

Many dream about making the planet a better place – only a determined few dedicate their lives to actually making it happen.

When it comes to nutritional supplements, there are hundreds of details that must be controlled to attain the highest quality, and as a manufacturer you truly have to believe in your work to spend decades refining the procedures and identifying the best suppliers needed to achieve such high goals.

We, at Lidtke, are a specialty manufacturer and in order to live up to our philosophy, we take the time to understand each ingredient so that we can discern small but important differences in quality.

As worldwide levels of radioactive nuclides, heavy metals, solvents, pesticides, herbicides and GMO ingredients continue to increase, the challenge to live a healthy life, we believe, becomes a worthwhile priority.

Be well in mind, body, and spirit!

We Thought You'd Like To Know...

At Lidtke, we are concerned about contaminants, the kind of organic and inorganic chemical contaminants, including solvents, fumigants, and heavy metals, that you may find in foods or supplements.

A few of the chemicals identified include acetone, toluene, hexane, ether, 1,2-dichloroethane, ethyl acetate, isopropyl alcohol, and ethylene oxide. These chemicals may, unknown to the bottler or consumer, be used in manufacturing processes.

Generally, nutritional ingredients are tested only for a few contaminants, and the other, untested toxic solvents, fumigants, pesticides and herbicides can be hundreds of times higher than safety standards.

The average consumer, in fact, would be surprised how often such solvents and other chemicals are used in the manufacture of “natural” products. Toxic residues such as these are more commonly found in low-cost nutrients because manufacturers can dramatically reduce their expenses by leaving out critical purification steps. Sorry to say, such residues seldom can be detected by consumers, and their illnesses, years in the future, may never be diagnosed.

These are the reasons why we believe it is important to work with respected suppliers of ingredients and raw materials – those who share our commitment to purity and safety. Please feel free to mail us your suggestions!
