Do we really need supplements? The unvarnished truth

The truth about dietary supplements: how to avoid harming yourself and when to get tested before starting any supplement.

Dietary supplements — myths, truth, and risks

Vitamin D, omega-3, magnesium, coenzyme Q10, melatonin, collagen, probiotics — the dietary supplement market is growing rapidly. While supplements were once mainly for athletes and the elderly, today everyone takes them: teenagers, pregnant women, IT specialists, bloggers. But are they a cure-all? Or just a marketing bubble?

How is a supplement different from a medication?

A supplement is not a medication. It does not treat disease but only complements the diet and, in theory, improves bodily functions. Unlike drugs, supplements do not undergo multi-level clinical trials, are not tested for safety in combination with other substances, and have no standard dosages.

In other words — a supplement's effect may or may not exist. Side effects, however, are quite real. Especially with uncontrolled use.

Benefits of supplements: when are they truly needed?

Supplements can be useful, but only when indicated. Here are a few examples:

  • Vitamin D — for deficiency (less than 30 ng/ml)
  • Omega-3 — for high triglyceride levels or inflammation
  • Magnesium — for anxiety, cramps, sleep disturbances
  • Probiotics — after a course of antibiotics
  • Folic acid — when planning a pregnancy

But taking them randomly, "for prevention," without knowing the levels of these substances in the blood, is a lottery. You may end up with vitamin overload, allergic reactions, or extra strain on the liver and kidneys.

When can supplements cause harm?

Taking supplements without testing and medical supervision is especially dangerous in the following cases:

  • With chronic conditions: diabetes, hypertension, oncology
  • While on medications — especially hormonal, anticoagulants, psychotropics
  • During pregnancy and breastfeeding
  • With allergies and autoimmune disorders
  • In children — due to sensitivity to ingredients

There are supplements containing iron, iodine, and potent herbal extracts (ginseng, eleuthero) that can cause blood pressure spikes, insomnia, and tachycardia.

How to approach taking supplements correctly?

The first and main rule: never take supplements based on internet "reviews." Even if a blogger says it is "just magic" — they have different test results, lifestyle, and chronic conditions.

Before starting, it is important to:

  • Get tested: vitamin D, B12, ferritin, magnesium, omega-3, zinc, calcium
  • Consult a general practitioner or endocrinologist
  • Determine the duration of intake, dose, and form
  • Repeat tests after 1–2 months and track the effect

Even the most "natural" supplements still interfere with how the body works. And one must be cautious about that.
