Creatine Gummies: Side Effects & Safety
Creatine has been studied for decades across hundreds of trials, and its safety record is excellent. Most of the 'side effects' you've heard about are myths — but a couple of real ones are worth knowing.
Does creatine hurt your kidneys?
No — not in healthy people. Long-term studies show no harm to kidney function in healthy adults. The myth comes from creatine slightly raising creatinine, a marker labs use to estimate kidney function — but that's a harmless byproduct of creatine metabolism, not damage. If you have existing kidney disease, talk to your doctor.
Does creatine cause hair loss?
There's no solid evidence that it does. The fear traces back to a single small study that measured a hormone (DHT), not actual hair loss, and it has never been replicated. See our full write-up on creatine and hair loss.
Does creatine cause bloating?
At a steady daily dose, no. Bloating was linked to old high-dose 'loading' protocols — about 20g a day for a week, which fills your muscles with water fast. Skip loading and take a steady daily dose, and there's no early water-weight spike.
The one real downside
The most common real side effect is mild stomach discomfort, usually from taking too much at once (loading) or on an empty stomach. Sticking to a steady daily dose with food solves it for almost everyone. With gummies, the thing to watch is added sugar.
