Other tools you may find usefulCreatine calculator 2026 online. Calculate the dose for your weight, goal and protocol
The following is a complete guide to the Livewire addon that calculates your creatine monohydrate dose. Here you will find the logic of the algorithm, justification of the thresholds, user manual, step-by-step examples, kitchen conversion factors, most common errors, a security section, as well as implementation tips for developers. Everything is consistent with the view and component class you passed.
What the calculator calculates and who it is intended for
The calculator answers three practical questions. How many grams of creatine per day to take in maintenance mode. Is it worth using loading and what should be the daily supply and how much is a serving for a given number of servings per day? How to measure a dose when you only have a kitchen spoon or a standard measuring cup. The solution will be used by people who train strength, endurance sports enthusiasts, users on a plant-based diet and trainers who prepare quick recommendations for their clients. The interface is clear and the recommendations are within safe and reasonable limits used in sports practice.
Input data and validation
The form accepts body weight in kilograms, supplementation goal, protocol selection and charging parameters. Validation defends borders. For body weight 30 to 250 kg, for loading days 3 to 7, for the number of servings 2 to 6. Goal selection limited to strength, general, vegan. The protocol selection is no_load or load. If the user is in non-loading mode, the loading-related fields are hidden, simplifying the interface and reducing errors.
Algorithm. Where the
numbers come from The logic starts with a weight-based maintenance dose. We assume 0.03 g per kilogram of body weight per day, but we stick to the practical minimum of 3 g and maximum of 5 g. We then make slight adjustments to the goal. The general variant reduces the result by about 10 percent, but does not allow it to go below 3 g. The vegan variant increases the result by about 10 percent, but does not allow it to exceed 5 g. This mechanism keeps the result within a practical range for most users and protects against exaggeration.
| Step | Formula | Description |
|---|---|---|
| Base | base = 0.03 × weight | Start from 0.03 g per kg body weight |
| Clamp | base = min(5.0, max(3.0, base)) | Practical limits 3 to 5 g |
| Target | general: base × 0.9, vegan: base × 1.1 | Correction down or up while maintaining limits |
| Projection | maintenance_g = round(base, 1) | Presentation with 1 decimal place |
| Loading | loading_daily = min(30, 0.3 × weight) | Quick saturation for several days, ceiling 30 g |
| Division | serving = loading_daily ÷ servings_per_day | Portion within the daily supply |
On the presentation side, we also provide the equivalent of a teaspoon and a measuring cup. We take 3 g in a teaspoon and 5 g in a measuring cup. This is a simplification. Manufacturers use different measures, so we treat the values as approximate and communicate them in the interface.
User Instructions
- Enter your body weight in kilograms. For reliability, it is best to use the morning measurement.
- Select a target. Strength is a profile focused on resistance training. General is a recreational profile. Vegan takes into account lower creatine intake in the diet.
- Select protocol. If you care about convenience, choose no charging. If you want to reach saturation faster, select charging.
- If you chose to load, set the number of days and number of servings per day. The standard is 5 days and 4 portions.
- Click Calculate and read the maintenance dose card and the loading card.
- Pay attention to the teaspoon and measuring cup conversion factors. These are approximations. The most accurate measurement is a scale.
Extended calculation examples
Recreational variant, 62 kg, without loading
Base 0.03 × 62 gives 1.86 g. After entering a minimum of 3 g, we get 3.0 g. General profile reduces by 10 percent, but cannot go below 3 g. The result remains at 3.0 g. Calculated per teaspoon it's about 1.00, per measure 0.60. It is most convenient to take one level teaspoon once a day with a meal.
Strength variant, 76 kg, loading 5 days and 4 portions
Maintenance dose of 0.03 × 76 is 2.28 g, after a minimum of 3 g the result is 3.0 g. Loading 0.3 × 76 is 22.8 g per day, which is within the 30 g limit. Dividing into four portions gives 5.7 g per serving. We round it up to 5.7 g. Converted into scoops, this is approximately 1.14 scoops per serving. After 5 days we return to 3 g per day.
Vegan variant, 96 kg, unloaded
The 0.03 × 96 base is 2.88 g. With the correction plus 10 percent we get 3.17 g, which when rounded to one place gives 3.2 g. That's approximately 1.07 teaspoons and 0.64 measuring cups. The no-load strategy will be comfortable, especially if you have a tight schedule.
Extended guide table
| Body weight | Strength | General | Vegan | Spoons approx. | Measuring cups approx. |
|---|---|---|---|---|---|
| 50 kg | 3.0 g | 3.0 g | 3.3 g | 1.10 | 0.66 |
| 60 kg | 3.0 g | 3.0 g | 3.3 g | 1.10 | 0.66 |
| 70 kg | 3.0 g | 3.0 g | 3.3 g | 1.10 | 0.66 |
| 80 kg | 3.0 g | 3.0 g | 3.3 g | 1.10 | 0.66 |
| 90 kg | 3.6 g | 3.2 g | 4.0 g | 1.33 | 0.80 |
| 100 kg | 3.9 g | 3.5 g | 4.3 g | 1.30 | 0.86 |
| 110 kg | 4.2 g | 3.8 g | 4.6 g | 1.40 | 0.92 |
| 120 kg | 4.5 g | 4.1 g | 5.0 g | 1.50 | 1.00 |
The table supports quick decisions. The values in the tool are calculated exactly for the entered weight and then presented with one decimal place. The teaspoon and measuring cup conversion rates are indicative. When communicating, use the words approximate and about, and recommend a kitchen scale whenever possible.
Practical tips for taking
- Take a serving with a meal. Better tolerance and comfort in your daily routine.
- Remember to stay hydrated. Creatine supplementation increases fluid requirements.
- Divide the loading dose into equal portions every 3 to 4 hours.
- On non-training days, keep the same dose as on training days.
- If you have a sensitive stomach, reduce portion size and increase frequency.
Frequently asked questions and answers
Does the time of day matter
The most important thing is consistency and daily intake. The time is of secondary importance. A good habit is to take a portion after a main meal or after training, because it makes it easier to remember to supplement.
Do you have to do cycles
The tool does not impose cycles. Many users use creatine continuously at a maintenance dose. If you want to plan breaks, treat them as a separate element of the strategy, it does not affect the calculator's algorithm.
What are the contraindications of
People with kidney or liver diseases, unregulated hypertension, pregnant and breastfeeding women should consult supplementation with a doctor. The calculator is not medical advice and does not replace a qualified consultation.
Does the form of creatine matter
The calculator is based on monohydrate. Other forms may have a different content of pure creatine per measure and technological additives. For such products, we suggest entering doses in grams according to the label and using the scale.
Why the 30 g limit was introduced when loading
The limit protects against excessively high intake in a single day, which reduces the risk of stomach discomfort. If you have a very large body weight, dividing into a larger number of portions makes more sense than exceeding this limit.
Common errors and corrections
- Skipping chunks while loading. Solution: Set reminders and tie portions to meals.
- Estimation by eye without scale. Solution: use the manufacturer's measuring cup or kitchen scale.
- Jumping between protocols every few days. Solution: Choose a 4 to 6 week strategy.
- Water supply too low. Solution: Aim for regular small amounts of fluids throughout the day.
Implementation in the project. Developer Notes
The Livewire component has public properties consistent with form and result cards. Validation rules enforce valid ranges, and the compute method implements formulas, rounding, and conversions. The teaspoon and measuring cup ratios are calculated at the end once the target grams have been set. Recording the history is optional and safely wrapped in a try catch block. If there is a History model in the project, a lightweight record with details of the call along with the date and IP address will be added to the database. If the model is missing, the method silences exceptions.
Tech Tips
- Add aria and role labels to selection buttons to improve accessibility for screen readers.
- Use the same number format with a decimal separator in the results section to avoid visual discrepancies.
- Move language versions to translation files. Texts in the view should use i18n keys.
- Add component tests for three scenarios: force without charging, force with charging, vegan without charging.
Extended test scenarios
| Scenario | Input | Expected result |
|---|---|---|
| Strength without loading | weight 80, goal strength, protocol no_load | maintenance approx. 3.0 g, no loading fields |
| Strength with loading | weight 80, protocol load, days 5, servings 4 | loading approx. 24.0 g, portion approx. 6.0 g, maintenance approx. 3.0 g |
| Vegan without charging | weight 100, goal vegan | maintenance approx. 3.9 to 4.3 g after correction, do not exceed 5 g |
