Jonna Wallberg, mum of 2, trains 6 mornings a week

Two kids, a 4:30am alarm, six mornings a week. I feel sharper now than I did at 25.

That is the only quiet hour I get, and it is when I train. One OneFit® sachet before I start covers the protein, the creatine, the probiotics and the electrolytes, so it is one thing to remember instead of six.

My alarm goes off at 4:30am, before my kids wake up.

There was a shelf of tubs in my kitchen and most mornings I’d get to the gym having taken none of them. That is the only quiet hour I get, so whatever I take has to be done in the time it takes the kettle to boil.

I managed some of the busiest restaurants in Bondi.

I know what running on empty feels like, and I know what it costs you two days later. I was not going to do that to myself again, and I did not have the headspace to manage six separate things to stay out of it.

I’ve just never been willing to feel like I can’t.

Two kids, a business and six mornings a week. The day does not get easier, so I would rather be the one who can keep up with it.

I wasn’t going to wait until I felt it drop.

I started thinking seriously about how you hold on to energy as you get older, rather than waiting until it was already gone and trying to claw it back. The 5g of creatine I used to skip is the part that keeps the muscle I train for.

I’m not sore for days like I used to be.

I have trained almost every day for about five years. What I noticed in the past six months is the recovery rather than the session, with 25g of protein and 5g of creatine in before I start.

It has all my protein, probiotics and electrolytes.

One 35g sachet: 25g of protein, 5g of creatine monohydrate, 20 billion CFU of Lactobacillus paracasei, 181mg of magnesium and 16 vitamins and minerals, at 100 calories. Every amount is printed per serve, so you can check it before you trust it.

It saves me time and energy having it all in one.

I can keep up with the kids and feel good in my body, and the whole thing costs me about thirty seconds a morning. I am not chasing a transformation, I just want the next thirty years to feel like this.

The questions everybody asks.

Is creatine safe long term? What about my kidneys?

Creatine monohydrate is one of the most heavily studied supplements in existence. Across controlled trials, adverse events have been mild and comparable to placebo, and kidney markers unchanged.

That said, if you have existing kidney disease or take medication that affects kidney function, this is a question for your doctor rather than a product page.

Will it give me the energy to get through the day?

Not the way an energy drink would, and we would rather say so plainly. There is no caffeine or stimulant in it.

What it does carry is 25g of protein and the B vitamins that contribute to normal energy release from food, on the mornings when breakfast does not happen. If you are exhausted in a way that sleep is not fixing, that is a conversation for your GP rather than a product page.

Do I have to train for this to be worth it?

No. Most of what is in the sachet is everyday nutrition: protein, magnesium, a probiotic, 16 vitamins and minerals. That does its job whether or not you make it to the gym.

The creatine is the part that pays off most alongside resistance training, and two sessions a week is the figure the evidence keeps landing on, not six. If you train, it helps. If this is a week where you do not, you have still had the rest of it.

Is one sachet really the same as taking all six separately?

On the amounts, yes, and that is the whole reason to check the panel rather than take our word for it. Every dose is printed: 25g of protein, 5g of creatine monohydrate, 181mg of magnesium, 20 billion CFU and 16 vitamins and minerals per 35g serve. There are no proprietary blends hiding a pinch of something behind a name.

What one sachet cannot replace is anything your doctor has you on. This is food, not medication, and it does not stand in for a prescription.

How much is in OneFit®, and how do I take it?

25g of protein and 5g of creatine monohydrate per 35g serve: one sachet or one scoop, shaken into 300ml of water. One serve daily. Creatine works by saturating over time, so taking it every day matters more than when you take it.

When should I take it?

Whenever you’ll actually remember it, at the same time each day. Daily consistency matters more than perfect timing. A serve taken every day beats a better-timed one taken twice a week. If you train, after training is a sensible anchor.

Who is it for?

People who train at least a few times a week and want one daily serve covering protein, creatine, electrolytes, probiotics and micronutrients instead of managing four or more separate products. It isn’t a weight-loss product and it isn’t a replacement for meals.

How does it fit into a daily routine?

It replaces the stack rather than adding to it. One sachet after training covers what most people were buying as four separate tubs. The formula is built around lean mass and probiotic among them. The gut ingredient is a named strain at a printed count sitting beside 25g of protein and 5g of creatine, rather than being sold on its own.

What if I don’t like it?

You’re covered by a 90-day full refund guarantee, and you can cancel or pause a subscription at any time. If it’s the flavour rather than the formula, the flavour promise lets you swap within 24 hours.
