Why HCL, not monohydrate?
Creatine monohydrate is the most-studied form — but it barely dissolves in water. Drop 5g into hot coffee and you get a gritty, clumping mess that settles to the bottom.
Creatine HCL is 38× more water-soluble. At 3g per pod, it dissolves completely and invisibly during your brew. Your coffee looks and tastes exactly like coffee.
The effective dose is also lower — 3g HCL delivers the same creatine load as roughly 5g monohydrate, without the bloating or water retention.

Why We Chose Creatine HCL (And Why It Matters in Your Coffee)
Creatine monohydrate is cheap, well-studied, and popular. It's also gritty, bloating, and barely soluble. Here's why HCL changes everything for functional coffee.

How to Build a Morning Routine That Actually Sticks
Most morning routines fail because they require too much. The research on habit formation points to one principle: make the good behavior the path of least resistance.
Creatine Coffee — answered.
Can you put creatine in your coffee?+
Yes — but only if you use the right form. Creatine monohydrate won't dissolve fully in hot coffee and leaves grit. Day One uses Creatine HCL, which is 38× more soluble and dissolves completely during the brew cycle. No residue, no texture change.
What are creatine coffee K-Cups?+
Creatine coffee K-Cups are standard K-Cup pods that contain both coffee and creatine — pre-measured and integrated at the manufacturing level. Day One's pods deliver 3g of Creatine HCL per cup, fully dissolved, with no additional mixing required.
Is it safe to drink creatine coffee every day?+
Yes. Creatine is one of the most extensively studied supplements available. Long-term safety studies — including a 16-month trial at 10g/day — show no adverse effects on kidney or liver function. 3g per day is well within the range consistently shown to be safe.
How much creatine is in each Day One pod?+
Each pod contains 3g of Creatine HCL — the optimal daily dose supported by peer-reviewed research. This is clinically equivalent to approximately 5g of creatine monohydrate, without the bloating or grit.
What makes Creatine HCL better than monohydrate for coffee?+
Solubility. Creatine HCL is 38× more water-soluble than monohydrate. At 3g per pod, it dissolves completely and invisibly during brewing. Monohydrate at 5g cannot fully dissolve in an 8oz cup, resulting in a gritty, unpleasant texture.
Can you take too much creatine? Are there limits?+
At normal doses, no — there is no established upper limit for healthy adults and no evidence of harm from daily use at 3–5g. Very high doses (10g+/day over long periods) have also been studied without adverse effects. That said, more is not better: once your muscles are saturated, excess creatine is simply excreted. 3g of Creatine HCL per pod is the optimal daily maintenance dose — effective, not excessive.
Will I notice the taste of creatine in my coffee?+
No. Creatine HCL at 3g is tasteless when fully dissolved, and because it dissolves completely during the brew cycle, there is nothing left to taste. Your coffee tastes exactly like coffee — no bitterness, no chalkiness, no aftertaste.
What coffee machines are compatible with Day One K-Cups?+
Day One pods work with every Keurig brewer ever made — Keurig 1.0, 2.0, K-Elite, K-Supreme, K-Slim, K-Mini, K-Duo, and all other K-Cup compatible machines. If it brews a K-Cup, it brews Day One.
Start Day One.
One pod every morning. The simplest performance upgrade you'll ever make.
