Jennifer Ashton Instagram – As someone with a Master’s Degree in Nutrition, I get this question all the time: “Can I add creatine to my coffee?” because of a concern about the coffee inactivating the creatine… ☕️💪
Here’s the truth — The science here is inconclusive.
1️⃣ As many studies show positive effects as show negative or neutral ones.
2️⃣ There’s something called the food matrix — the form of a given food and what it’s mixed with matters.
3️⃣ Potential downsides? GI upset or dehydration — both are possible with creatine or caffeine on their own; combining them can increase that risk.
Here’s a great review on creatine with a special section on combining it with caffeine. Antonio, J., et al. (2024). Part II. Common questions and misconceptions about creatine supplementation: what does the scientific evidence really show? J of the Intl Soc of Sports Nutrition, 22(1). It sums up this issue with this comment: “”short-term Creatine monohydrate and caffeine ingestion (<5 mg/kg/day) likely does not cause opposing muscle effects. The long-term possible interference effects of CrM and caffeine are unknown.””
There’s no one-size-fits-all answer here — and if someone says otherwise, they’re probably not qualified to be giving that advice.
