Creatine might be the most studied supplement in sports nutrition. It's also one of the simplest. There's not much to it: one ingredient, a scoop a day, and patience.

That makes the brand you pick mostly about purity. That's where Thorne Creatine earns its spot, and why it holds 4.7 stars from more than 18,000 Amazon ratings.

What creatine does

Your muscles store creatine and use it to quickly recharge their energy during short, hard efforts. Think of the last few reps of a set, a sprint, or jumping up a flight of stairs. Topping up those stores is why creatine is so popular with people who lift.

Thorne describes it like this. Creatine promotes lean body mass, supports muscle endurance, capacity and power output, and helps cells create energy more efficiently, which benefits exercise capacity.

Then there's the part that surprises people. Thorne also notes that creatine has been shown to support cognitive function. Your brain uses creatine for energy too, and that's a big reason it's being talked about well beyond the weight room, including by older adults and people who don't eat meat.

Why micronized monohydrate

Creatine monohydrate is the form used in the overwhelming majority of research. Micronized means the powder is milled into finer particles, so it stirs into water more easily and doesn't sit at the bottom of your glass like sand.

It's unflavored. You can add it to coffee, a smoothie, juice, or a protein shake and barely notice it.

The NSF Certified for Sport seal

Here's what sets this tub apart. It's NSF Certified for Sport. That program tests products to make sure the label claims are accurate and that there are none of the nearly 300 substances banned by major athletic organizations.

If you're a competitive athlete, that seal is often required. If you're not, it's still a reassuring sign. You know what you're scooping, and nothing else.

Thorne also says it's trusted by more than 100 professional sports teams, and it's the brand many dietitians and trainers reach for first.

Making it a habit

Follow the serving on the tub, once a day. Timing isn't critical. Before training, after training, with breakfast, it all works, because what matters is taking it consistently so your muscles stay topped up. Many people simply stir it into their morning drink so they don't forget.

Drink plenty of water through the day. Creatine pulls water into your muscles, and a lot of people notice the scale goes up a pound or two in the first weeks. That's water in the muscle, and it's normal.

You can skip the old loading phase. A steady daily dose gets you to the same place in a few weeks with less chance of an upset stomach.

The value

This tub has 90 servings, three months, and was listed at $44.00 when I checked. That's about 49 cents a day. You can find cheaper creatine, but at this price you're paying for the certification and the Thorne testing behind it, and for a lot of people that's worth it.

A couple of sensible notes

If you have kidney disease, or you take medicines that affect the kidneys, talk with your doctor before starting creatine. Also let your doctor know you take it before blood work, because it can nudge creatinine, a lab marker of kidney function, a little higher. Pregnant or nursing? Check with your provider first.

Simple, clean, proven

If you've been curious about creatine for strength, training or even brain support, this is one of the cleanest ways to begin. One ingredient, independently certified, easy to mix. Take a look at Thorne Creatine and see if it earns a place in your morning routine.
