How a daily 3–5 g of creatine fills your muscles, what the strength meta-analyses found, and what is still early on memory.
Key Takeaways
- Taking 3 g a day raised muscle creatine by about the same amount as a 20 g loading phase. It just took 28 days instead of 6.
- Across 53 trials, creatine produced a small, consistent gain in upper-body strength. Across 60 trials, the same was true for the legs.
- The ISSN says 3–5 g a day is enough to keep stores topped up. Our gummies give you 5 g.
- Research on memory and thinking is promising but early.
Why Creatine Is the Most-Studied Supplement in Sports Nutrition
Your muscles store creatine as phosphocreatine. It is the fuel you burn in the first few seconds of hard effort, like a heavy lift, a sprint or a jump. Diet provides some, mostly from meat and fish. Supplementing raises those stores further, and that is where the performance effects come from.
The International Society of Sports Nutrition reviewed the full body of evidence in 2017. It concluded that creatine is safe and well tolerated in healthy people, even at up to 30 g a day for five years. That is six times what our gummies provide.
Do You Need to Load? The 1996 Study That Answered It
A 1996 study took muscle biopsies from men on two schedules. One group took a 20 g-a-day loading phase for 6 days. The other took 3 g a day for 28 days. Both groups ended up with a similar increase.
This is why our gummies skip the loading phase. A daily 5 g tops up stores steadily, with no stomach-churning 20 g days. The NIH describes the same pattern: an optional loading phase, then 3–5 g a day.
What the Strength Meta-Analyses Found
A meta-analysis pools many trials to get a more reliable answer than any single study. A French team ran two of them. The first covered lower-limb strength (60 studies, 1,297 people) and the second covered upper-limb strength (53 trials, 1,138 people). Both found a small, statistically significant benefit over placebo.
What About the Brain?
Your brain also uses creatine for energy. A 2018 systematic review of six randomized trials (281 people) found some evidence that short-term memory and reasoning may improve, especially in vegetarians, who get little creatine from food. In young people, performance mostly stayed the same. The trials were small and varied, so we treat this as a promising area rather than a promise.
How Our Dose Compares
| What Was Measured | Amount Studied | DLNIA Amount |
|---|---|---|
| Maintaining muscle stores (ISSN, NIH) | 3–5 g a day | 5,000 mg micronized creatine monohydrate in 4 gummies |
| Steady filling without loading (Hultman 1996) | 3 g a day for 28 days | 5 g a day, so at or above the tested amount |
| Long-term safety (ISSN review) | Up to 30 g a day for 5 years | 5 g a day |
What the Research Does Not Show
Most trials test creatine alongside resistance training. Without training, expect little change in strength. Creatine can raise body weight by a kilogram or so, largely from water held in muscle. If you have kidney disease or take regular medicine, check with your doctor first.
