Vitamin and Mineral Guide: Deficiency, Tests, and Safe Supplementation

Short answerThe most appropriate approach to vitamin and mineral supplementation is not “the same supplement for everyone,” but rather evaluating diet, age, medical conditions, medications, and the actual risk of deficiency together. A supplement does not replace a laboratory test or medical evaluation.

How is a deficiency evaluated?

The same method is not used for every vitamin. Blood tests are useful for some nutrients; others are interpreted together with clinical history, diet, and risk factors. For example, 25-OH vitamin D, B12, folate, and iron/ferritin can be measured directly in certain situations. It is not possible to reliably identify all vitamin and mineral deficiencies with a single “energy” or frequency test.

Who may be at higher risk of deficiency?

  • People with restrictive or unvaried diets
  • People following vegan/vegetarian diets, especially with regard to B12
  • People with a history of malabsorption, celiac disease, inflammatory bowel disease, or bariatric surgery
  • Older adults
  • People taking certain long-term medications
  • During periods of increased requirements, such as pregnancy and breastfeeding

More is not always better

The fat-soluble vitamins A, D, E, and K and some minerals can accumulate at high doses or interact with medications. Some water-soluble vitamins, such as B6, can also cause toxicity when used at high doses for a long time. Therefore, the goal is not a “high dose,” but a dose appropriate to the need.

Does bioresonance reveal vitamin deficiencies?

Bioresonance has not been shown to reliably detect vitamin or mineral deficiencies in place of standard laboratory tests. When a deficiency is suspected, clinical evaluation and appropriate laboratory methods should be the basis for assessment.

Our approach at our Bodrum clinic

We develop the supplementation plan by considering symptoms, diet, medications, and laboratory findings together. We place importance on avoiding unnecessary high doses and taking the same ingredients repeatedly through multiple products.
