Unlike medicines, supplements are not strictly regulated. Dosage recommendations are often based on research rather than FDA approval.

Timing Matters

The effectiveness of some supplements depends on timing. For example, creatine is better absorbed after training with carbohydrates.

💡 Practical Tips

⚠️ Important to Know: Never exceed the recommended dose thinking that "more = better". Too high doses can be toxic (e.g., vitamin D, iron, zinc). Before starting any supplement, consult a doctor, especially if you are taking medications.

How to Use the Calculator

The supplement dosage calculator helps calculate an approximate supplement dose based on body weight or other entered data. Enter your weight and select a supplement, and the tool will suggest a dose according to standard recommendations.

Remember that this is an indicative tool — before starting use, it is worth checking with a specialist, especially if you take medications or have health conditions. The calculator does not take individual circumstances into account, so treat the result as a starting point.

How to Interpret the Result

The suggested dose is a general recommendation, not an individual prescription. Consider your diet: if you already get the supplement from food, your need may be lower. Start with a lower dose and monitor how you feel, and increase the dose gradually.

More is not always better — an excess of some substances can be harmful. If you take several supplements, check that their ingredients do not duplicate.

Common Mistakes

When the Calculator Does Not Help

The calculator will not help if your main diet is unbalanced — supplements only supplement, not replace, food. Check doses for specific supplements in separate tools: creatine dose, caffeine dose or protein requirements.

🙋 Frequently Asked Questions

Can Several Supplements Be Combined? It is possible, but start one at a time and monitor the effect so you know what works.

When Should You Take Supplements? Timing depends on the specific supplement; general recommendations can be found in the respective tools.

Are supplements necessary? For most people, the priority is to first get nutrition, sleep and training in order — supplements are only an addition.

Do Children Need Different Doses? Yes, doses differ for children and adolescents and should be determined by a specialist — do not use adult doses.

What to Do If You Miss a Dose? Usually there is no need to double the next dose; simply continue your usual regimen.

Store supplements according to the manufacturer's instructions and pay attention to the expiration date — an expired product may lose effectiveness. Always match the dose to a specific need rather than taking it "prophylactically".

Pay attention to timing and combining with food — some supplements are better absorbed with food, others on an empty stomach. These recommendations are usually provided by the manufacturer, so follow them rather than experimenting on your own.

If you are unsure whether you need a supplement, first evaluate your diet and only then decide on supplements — often simple changes deliver more than expensive products.

📚 Scientific Basis

Supplement doses are not universal — they depend on the substance, goal and person. Textbooks emphasize that a supplement is a supplement to food, not a replacement for it, so it is worth first ensuring that your diet covers the need.

Two practical principles: (1) start with the lowest effective dose, (2) take one supplement at a time so you can tell what works and what doesn't.
