The molecule behind every cup

Three compounds.
One extraordinary ritual.

When specialty coffee meets high-flavanol cacao, three naturally occurring compounds give F-100 its character — a smooth lift, rich flavor, and the antioxidant flavanols cacao is prized for. This is what's inside F-100.

C₇H₈N₄O₂
Methylxanthine
N C N N C C N C O O CH₃ CH₃

Theobromine

Cacao's Signature Alkaloid

A methylxanthine, chemically related to caffeine but structurally distinct. Its defining property is pharmacokinetic: theobromine is absorbed and cleared more slowly than caffeine.*

  • Half-life roughly 2–3× that of caffeine
  • Studied as a mild vasodilator
  • Naturally present — nothing added
  • What gives dark chocolate its bitterness
C₁₅H₁₄O₆
Flavanol
OH OH OH OH activates eNOS EPC EPC EPC

Epicatechin (Flavanol)

The Star Cacao Flavanol

Epicatechin is the primary flavanol in cacao and the most studied of its polyphenols — it's the compound COSMOS standardised its extract on. It's also fragile: alkalising strips most of it out, which is why we never Dutch our cacao.

  • The most studied flavanol in cacao
  • Destroyed by alkalising — ours isn't
  • Central to cacao's nitric-oxide pathway
  • Naturally antioxidant-rich polyphenol

The COSMOS Trial

21,442 participants. 3.6 years. COSMOS was one of the largest randomized trials ever run on a cocoa flavanol supplement — a big reason we build F-100 around real, high-flavanol cacao rather than a flavoring.

Cacao is one of the richest natural sources of flavanols — the plant compounds researchers have studied for years. And now they're in the coffee you were already going to brew.

Caffeine + Theobromine

Cacao brings theobromine alongside coffee's caffeine. The two are chemically related, but theobromine is absorbed and cleared more slowly — so every cup carries both.*

Antioxidant-Rich

Epicatechin is the most studied flavanol in cacao and a naturally potent antioxidant — a hallmark of high-quality, minimally processed cacao.

Origin & heritage

Grown in volcanic soil.
Cupped in the top 5%.

Our beans are sole-sourced from the volcanic highlands of Costa Rica, where mineral-dense earth and altitude produce a cup professional cuppers score at SCA 84 — specialty grade, the top 5% of coffee worldwide. It's better coffee before you even consider the cacao.

Then there's the cacao itself. Cultures across Mesoamerica drank it for millennia, long before anyone could name a flavanol. We're not claiming they knew something we've since proven — we're saying it's a very old ritual, and we keep ours minimally processed so what's in the bean survives to your cup.

The Functioning Centurion

Strong. Sharp. Active

Kevin Worley · Founder, F-100

A note from Kevin

"A Functioning Centurion uses science, fitness and lifestyle to slow aging — and stay strong, sharp and active past 100."

I didn't start F-100 because I needed a new coffee. I started it because I got fascinated by the research on cacao flavanols — one of the most studied areas in nutrition — and couldn't un-read it. So we build every bag around real, high-flavanol cacao, sourced with care and kept minimally processed. That's what gets me up in the morning.

Questions, answered

Everything you want to know.

Theobromine (C₇H₈N₄O₂) is the primary alkaloid in cacao — a methylxanthine, chemically related to caffeine but with slower absorption and a longer half-life in the body. That pharmacokinetic difference is well characterised; what it feels like in a given cup, at the amounts present in food, varies a lot from person to person. We'd rather tell you what's in the blend than tell you how it will make you feel.*
Cacao is naturally rich in flavanols — especially epicatechin — the plant compounds it's prized for. They're linked to the body's nitric-oxide pathway, which is why cacao is associated with healthy circulation.* We source high-flavanol cacao and keep it minimally processed so those flavanols survive to your cup, instead of being stripped out by heavy processing.
Flavanols like epicatechin are fragile. Heavy alkalizing (Dutch processing) strips most of them out of ordinary cocoa. We keep our cacao minimally processed on purpose, so the flavanols that make cacao worth drinking actually make it into your cup. It's the whole reason we call it high-flavanol cacao.
F-100 is coffee and cacao — foods, not medicine, and we don't sell them as a treatment for anything. It does contain caffeine, so if you're sensitive to caffeine, pregnant or nursing, or you manage a health condition or take medication, check with your doctor first, just as you would with any coffee. These statements have not been evaluated by the Food and Drug Administration, and this product is not intended to diagnose, treat, cure or prevent any disease.
Honestly? A better cup of coffee. The taste difference is immediate — cacao gives it a rounder, darker body without any added sugar. Beyond flavour we're not going to promise you a feeling on a schedule; that isn't something we can substantiate, and anyone who does is guessing. What we can say is that cacao flavanols are studied at daily intakes, so if you're drinking it for the cacao, consistency is the part that matters.*
Here's the honest version. The largest trial to date, COSMOS, randomised 21,442 adults to a cocoa flavanol extract (500 mg flavanols, about 80 mg epicatechin daily) or placebo for a mean 3.6 years. Its primary endpoint — total cardiovascular events — was not met: the 10% reduction wasn't statistically significant. A pre-specified secondary endpoint, death from cardiovascular disease, was 27% lower. Separately, in 2023 the FDA said it would not object to a qualified health claim for high-flavanol cocoa powder, while stating its own view that the supporting evidence is very limited.

So: interesting, ongoing, not settled — and studied as a concentrated supplement, not as coffee. We're not going to tell you a bag of coffee reproduces a clinical trial. We'd rather publish what's actually in ours and let you decide.*
Yes — the actual certificates of analysis, by batch, as PDFs on our lab results page. Heavy metals (cadmium especially, since cacao takes it up from soil more readily than most crops), microbiological, mycotoxins, pesticide screen, and flavanol assay. "Third-party tested" means nothing without the paperwork behind it, so there's the paperwork.
High Performance Cacao is a 100% powder to stir into anything — coffee, smoothies, oatmeal. Ceremonial Cacao is single-origin, stone-ground for a richer ritual cup (think the traditional Mayan preparation). Chocolate Drops are 72% dark chocolate for an everyday snack that's rich in real cacao flavanols. All three are epicatechin-rich — pick the format that fits your day. The Coffee + Cacao is the easiest: it's already blended, so your morning brew delivers everything automatically.
