Creatine Benefits, Dosage, and Brain Health: What to Know

May 19, 2026

A pro golfer, a water bottle, and a clump of creatine walk onto the first tee.

That is not the start of a joke. It is basically what happened to PGA Tour player Ben Griffin at the BMW Championship. According to the PGA Tour, Griffin started his final round by taking creatine from his water bottle, accidentally swallowed what he called a big "rock" of it, did not drink enough water after, and suddenly felt shaky enough that he four-putted the first hole.

Then he hit one out of bounds on the second.

Then his caddie made him chug water, which may be the most accurate piece of sports nutrition coaching ever delivered under pressure.

The funny part: Griffin recovered and played the final 15 holes in 7-under.

The useful part: creatine is having a massive comeback, but the lesson is still boring in the best way. Dose it correctly. Mix it correctly. Take it consistently. Do not inhale a supplement snowball mid-round and ask your nervous system to act normal.

Creatine Used to Be Gym Powder. Now It Is Everywhere.

For years, creatine lived in a very specific corner of culture: weight rooms, shaker bottles, college athletes, and people arguing about loading phases like the fate of civilization depended on it.

That version still exists. Creatine monohydrate is one of the most studied sports supplements in the world because it helps your muscles recycle energy during short, hard efforts. Think lifting, sprinting, repeated bursts, and the kind of training where one more rep actually matters.

But the conversation has changed.

Creatine is now showing up in women's health coverage, aging conversations, brain-health podcasts, and longevity stacks. Bryan Johnson's Blueprint Longevity Mix includes creatine monohydrate alongside ingredients like glutathione, CaAKG, taurine, glycine, magnesium, and L-theanine. That does not mean everyone needs a longevity drink. It does mean creatine has officially left the bodybuilding aisle and entered the healthspan group chat.

So What Does Creatine Actually Do?

Creatine helps your body make and recycle ATP, the quick-access energy currency your cells use when effort gets intense.

In muscle, that matters because hard training burns through ATP fast. Creatine helps replenish it, which can support strength, power, training volume, and recovery between repeated high-intensity efforts.

That is the classic use case. It is why creatine became popular with lifters in the first place. It is not a steroid. It is not a stimulant. It is not a secret shortcut. It is more like adding a slightly bigger battery to a system that already works.

The normal baseline is simple: 3-5 grams per day of creatine monohydrate, taken consistently.

The Rhonda Patrick Brain-Health Angle

The newer conversation is about the brain.

On Huberman Lab, Dr. Rhonda Patrick talks about creatine as more than a muscle supplement. Her point is that the brain is also energy-hungry, and creatine may matter in contexts where energy demand is high: cognitive stress, sleep deprivation, aging, and potentially other brain-health scenarios. That is the thread that makes creatine relevant beyond the weight room.

The important nuance: the muscle research and the brain research are not identical.

Patrick has discussed 5 grams per day as the classic dose used in much of the muscle and performance literature. She has also talked about personally using a higher daily intake, split into doses, because the brain may require more creatine than muscle to meaningfully shift creatine availability in certain contexts.

That does not mean everyone should jump to a higher dose tomorrow. It means the "creatine is only for biceps" story is outdated.

The better frame: creatine is a cellular energy tool. Muscle was the obvious first market. Brain health may be the next major frontier.

The Golfer Lesson: More Is Not Always Better

Back to Griffin.

The internet version of the story is "golfer overdoses on creatine," which is clickable because of course it is. But the useful read is less dramatic and more practical: he took creatine in a bad format, at a bad time, without enough water, during a pressure situation where shaky hands are not exactly ideal.

That is not an argument against creatine. It is an argument against treating supplements like loose trail mix.

The basic protocol: use creatine monohydrate, take 3-5 grams daily, mix it fully into water or another drink, and take it consistently instead of randomly going big. Powder is the boring-but-reliable format. Capsules can also work if the math gets you to a real dose. Gummies need more scrutiny: look for real third-party testing, not just a label that says 5 grams in friendly typography. If experimenting with higher doses, split them and make sure your stomach tolerates it. Do not dry-scoop it. Do not take a mystery clump before doing something that requires fine motor control.

Simple tools still need simple rules.

The Gummy Problem

Creatine's popularity created the obvious next product: creatine gummies. Because why mix a powder when you can make your supplement feel like candy?

The problem is that gummies are a much harder format to get right. A recent WIRED story reported on independent testing ordered by SuppCo. Four of six popular creatine gummy products sold on Amazon contained almost no creatine or none at all. One product labeled as 5 grams per serving reportedly tested at 0.005 grams per serving. Translation: you would need roughly 2,000 gummies to get the listed 5-gram dose. That is not a supplement protocol. That is a hostage situation for your molars.

WIRED also noted that NOW Foods previously tested a dozen popular creatine gummy brands and found 5 of 12 failed, showing very little or no active ingredient. The issue is not just shady labels. Creatine can degrade into creatinine, and gummies often involve moisture, heat, and acidity — basically a hostile little spa day for an ingredient that is much easier to keep stable as a dry powder.

If the goal is a reliable 3-5 grams per day, creatine monohydrate powder is still the cleanest path. Gummies are convenient, but convenience only counts if the dose is real.

The Sleep-Deprived Brain Angle

This is where creatine gets more interesting than gym performance.

Sleep deprivation is basically an energy crisis with a calendar invite. Your brain still has to make decisions, remember where the diaper cream went, answer Slack without sounding unhinged, and drive like a person who has slept. Caffeine can make you feel more awake. It does not magically erase the metabolic cost of being up half the night with a baby, a deadline, or both.

A 2024 Scientific Reports study tested a single high dose of creatine monohydrate during a night of sleep deprivation. The researchers used brain spectroscopy and cognitive tasks across the night and reported improved cognitive performance along with changes in cerebral high-energy phosphates. In plain English: under sleep-deprived conditions, creatine appeared to help the brain's energy system hold up better.

Important caveat: this was not a normal daily dose. The study used 0.35 grams per kilogram, which is a big acute dose — roughly 25 grams for a 155-pound person. That is research-lab territory, not a casual Tuesday morning parenting protocol.

The practical takeaway is not “megadose creatine when your toddler wakes up.” It is that creatine's brain-energy role is real enough to study under sleep stress, which makes the everyday 3-5 gram habit more interesting than the old gym-powder stereotype.

The Practical Take

Creatine is not magic. It is a tool.

For strength training, it can help support repeated high-effort work. For brain health, the science is interesting enough that serious people like Rhonda Patrick are paying attention, especially around energy demand and higher-dose questions. For longevity culture, its appearance in products like Blueprint's Longevity Mix shows how far the category has moved.

But the protocol still matters more than the hype.

Start with 3-5 grams of creatine monohydrate per day. Mix it properly. Drink water. Take it consistently. If you choose gummies, make sure the brand has credible third-party testing showing the creatine dose is actually there. Do not expect to feel it like caffeine. Do not panic if it feels boring. Boring is kind of the point.

And if you are about to tee off in a professional golf tournament, maybe make sure there are no supplement boulders floating in your bottle.
