This spring, I told my doctor I was thinking about trying creatine. I am 63, I lift three mornings a week at the community rec center, and I wanted to keep the strength I have worked to rebuild since I retired from the post office. He did not wave it off. He asked about my kidneys, ran a blood test, and when it came back fine he said go ahead, five grams a day, and give it eight weeks before you judge it. I picked Optimum Nutrition creatine monohydrate because it was plain creatine monohydrate with nothing added, and because the scoop measured out five grams, which sounded like less fuss than weighing powder.

That is how I do everything these days. One new supplement at a time, at least eight weeks, with a spiral notebook where I write down my lifts, my bodyweight, and how I slept. I walked a mail route for 31 years, and when I stopped, the strength went with it faster than I expected. Carrying groceries up the porch steps got hard. Getting up off the floor got hard. So at 60 I started lifting, and it helped, but I knew I was still leaving something on the table.

Creatine is the supplement I read the most about before trying it. There is a lot of research on it, and a good chunk of that research looks at older lifters, which is exactly the group I am in. The plain summary is that it is one of the most studied supplements around, and the evidence points the same direction for most people: it can help you get a little more out of the training you are already doing. It does not do the training for you. Nothing does.

Here is what actually changed. In the first two weeks, my bodyweight went up about three pounds. That is water in the muscle, and it is expected, and it is not the kind of weight that bothers me. After about a month, I was getting a couple more reps on the leg press and the seated row at the same weight. A couple of reps. That is the honest size of it, and I think that is worth knowing, because most of what you read online makes it sound bigger than that.

I am not a supplement salesman, and I am not a young man with a camera. I am a retired letter carrier who wanted his strength back. That is why I keep a notebook and why I test one thing at a time. If something does nothing for me, I say so. This one did something, and I want to tell you exactly what, and exactly what it did not do.

Five grams a day, one scoop, no loading phase

That is the whole routine. Optimum Nutrition creatine monohydrate is unflavored, so it disappears into a chocolate whey shake on lifting days and a glass of water the rest of the week. See today's price on Amazon and give it your own eight weeks.

The practical details matter more than people think. One scoop is five grams. I take it every day, not just on lifting days. On Monday, Wednesday, and Friday it goes into the same shaker bottle as my whey, mixed with 2% milk, and it vanishes into the chocolate. On the other days it goes into a glass of cold water at breakfast, and I will be honest with you, a little grit settles at the bottom. It does not fully dissolve in cold water. It never bothered me, and it did not bother the results, but I would rather tell you now than have you think you did something wrong.

I also want to be straight about the limits. Creatine is not going to turn a 63-year-old into a 30-year-old. It did not make me look different, and nobody at the rec center has said a word. My joints did not hurt any more or less. My sleep did not change. My energy did not change. The only things that changed were a couple of reps on two exercises and about three pounds on the scale, and I am at peace with that, because at my age the goal is not a stage. The goal is carrying the groceries on the first try, getting up off the floor without using the couch, and keeping up with Joanne on our walks along the riverfront.

Before I switched to Optimum Nutrition, I used a tub of another brand of creatine for about a month, and it worked the same. I want to be clear about that, because you do not need the most expensive tub on the shelf, and nobody should pretend otherwise. I switched because I preferred this tub and this scoop, not because the powder inside was night and day. Unflavored creatine monohydrate is unflavored creatine monohydrate, and the research that matters is about the ingredient, not the label.

My doctor's instructions were simple, and I will pass them along. Talk to your own doctor first, especially if you have kidney concerns or take medication. Five grams a day is the dose the research uses, and it is the dose I use. And give it eight weeks before you decide anything, because the people who quit after a week quit before the supplement had a chance to do anything. That is not a sales pitch. That is just how long these things take.

What I'd Tell You If We Were Sitting at My Kitchen Table

Supplements come after food, sleep, and showing up. That is the order, and it does not change just because you are over 60. I get around 130 grams of protein a day, a number my doctor agreed with, I sleep decently, and I lift three mornings a week whether I feel like it or not. Creatine is the last thing in that line, not the first. If you are eating the way I used to, toast and coffee for breakfast and not much protein the rest of the day, fix that before you buy anything. And have the conversation with your doctor. Mine checked my kidneys first, and that is the conversation worth having. Then, if you lift, creatine is worth trying, and Optimum Nutrition is the tub on my pantry shelf. One scoop, five grams, every day, eight weeks. That is the whole thing.
