The standard creatine dose is 0.3 grams per kilogram of body weight per day during a loading phase, which works out to about 0.14 grams per pound. For a 180-pound person, that’s roughly 25 grams daily for 5 to 7 days. After that, a maintenance dose of 0.05 to 0.15 grams per kilogram (0.02 to 0.07 grams per pound) keeps your muscles saturated long-term.
If those decimals feel abstract, here’s the simple version: multiply your weight in pounds by 0.14 for your loading dose, or by 0.03 to 0.07 for your daily maintenance dose. The rest of this article breaks down exactly how to use those numbers and when you might not need a loading phase at all.
Loading Phase Dosing by Body Weight
A loading phase floods your muscles with creatine quickly, typically over 5 to 7 days. The target is 0.3 grams per kilogram of body weight per day, split into smaller doses taken roughly every 4 hours. Here’s what that looks like across different body weights:
- 140 lbs (64 kg): ~19 g per day
- 160 lbs (73 kg): ~22 g per day
- 180 lbs (82 kg): ~25 g per day
- 200 lbs (91 kg): ~27 g per day
- 220 lbs (100 kg): ~30 g per day
One level teaspoon of creatine monohydrate holds roughly 5 grams, so a 180-pound person would take about 5 level teaspoons spread across the day. If you want precision, a small digital kitchen scale is more reliable than eyeballing scoops.
Single doses above 10 grams can cause stomach discomfort because unabsorbed creatine draws water into the intestines. Splitting your daily total into 4 or 5 doses of 5 grams or less avoids this problem almost entirely.
Maintenance Phase Dosing by Body Weight
Once your muscles are saturated, you need far less creatine to stay there. The recommended maintenance range is 0.05 to 0.15 grams per kilogram per day, or roughly 0.02 to 0.07 grams per pound. For most people, this falls between 3 and 10 grams daily depending on body size.
- 140 lbs: ~3–10 g per day
- 160 lbs: ~4–11 g per day
- 180 lbs: ~4–12 g per day
- 200 lbs: ~5–14 g per day
- 220 lbs: ~5–15 g per day
That’s a wide range, and where you land depends on your goals and training intensity. Most recreational lifters do well at the lower end, around one level teaspoon (5 grams) per day. Larger or more heavily muscled individuals may benefit from the higher end of the range because they have more muscle tissue to keep saturated.
Skipping the Loading Phase
A loading phase isn’t required. Taking just 3 grams per day (a little over half a teaspoon) reaches the same level of muscle saturation, but it takes about 28 days instead of 5 to 7. The end result is identical. You won’t gain strength or size any faster by loading; you’ll just get to full saturation sooner.
This slower approach has a practical advantage: it’s gentler on the stomach and simpler to manage. You take one small dose per day instead of juggling four or five. If you’re not preparing for a competition on a tight timeline, there’s no real downside to skipping the load.
Total Weight vs. Lean Body Mass
Most dosing guidelines are based on total body weight, not lean mass. This works fine for people at a typical body fat percentage. But if you carry a significant amount of extra body fat, dosing by total weight could overshoot what your muscles actually need, since fat tissue doesn’t store creatine the way muscle does.
Research has tested both absolute dosing (a flat gram amount like 5 g/day) and relative dosing (grams per kilogram of body weight), and both approaches effectively raise muscle creatine levels. If you’re significantly overweight, using an absolute maintenance dose of 3 to 5 grams per day is a reasonable alternative to multiplying out a per-pound calculation. For most people in a normal weight range, the per-pound formula and a flat 5-gram maintenance dose land in roughly the same place anyway.
Water Weight Gain During Loading
Creatine pulls water into muscle cells, so expect some weight gain on the scale, especially during a loading phase. In one study, participants gained an average of about 3.7 pounds of total body water over the supplementation period with no change in body fat or calorie intake. This water retention is happening inside muscle tissue, not under your skin, so it doesn’t create a bloated appearance. The extra water is part of how creatine works: better-hydrated muscle cells function and recover more effectively.
If you’re tracking body weight for fat loss, keep this initial bump in mind. It’s water, not fat, and it stabilizes within the first couple of weeks.
Safety at Higher Body Weights
Heavier individuals end up with higher absolute doses when using per-pound calculations. A 250-pound person loading at 0.14 grams per pound would take about 35 grams per day. That’s within the studied range of 5 to 20 grams per day for general use, but at the extreme end for a loading phase.
The main concern at high doses isn’t kidney damage in healthy people. It’s gastrointestinal discomfort. Keeping each individual dose at 5 grams or less is the most effective way to avoid stomach issues, even if your total daily intake is high. A 250-pound person loading at 35 grams per day would split that into 7 doses of 5 grams spread throughout the day.
For people with pre-existing kidney conditions, the safety data is limited. Standard kidney function tests can be thrown off by creatine supplementation because creatine naturally raises a blood marker (creatinine) that doctors use to estimate kidney health. This doesn’t mean your kidneys are struggling; it means the test is reading a false signal. If kidney function is a concern, more direct measures of filtration rate or protein in urine give a clearer picture.
Quick Reference Formula
For a loading phase: multiply your body weight in pounds by 0.14. Take that many grams per day, split into doses of 5 grams or less, for 5 to 7 days.
For maintenance: take 3 to 5 grams per day (one level teaspoon) if you’re under 200 pounds. If you’re over 200 pounds or training at a high intensity, 5 to 10 grams per day is a reasonable range. Or skip the loading phase entirely and start at 3 to 5 grams per day, reaching full saturation in about four weeks.
