My actual stack.

The supplements I take every morning, the tools I use for hours a day, and the gear that quietly runs in the background. Updated when things change.

supplements

What I take daily.

OTC stack built with a dietitian. Every item has a specific job; nothing is here for vibes. For standalone supplements I default to Momentous — NSF Certified for Sport, third-party tested.

Heads up: I'm not a doctor and this isn't advice. My stack was designed with labs in hand and professional guidance. What works for me may not be right for you.

foundation

Thorne Essential Multi

The base everything else builds on. Methylated B12 and folate (actually absorbed), D3 + K1/K2 (MK-7), zinc/copper at the right ratio, and a comprehensive mineral set — all third-party tested.

4 caps morning with fat
cardio · anti-inflammatory

Omega-3 Fish Oil

High-dose EPA+DHA at 1,600 mg combined. Cardiovascular support and long-term anti-inflammatory maintenance. Sourced for purity — check for third-party testing on whatever brand you use.

1,600 mg EPA+DHA morning with fat
mitochondrial energy

CoQ10 Ubiquinol

The reduced (ubiquinol) form absorbs meaningfully better than plain CoQ10. Mitochondrial support and antioxidant — pairs well with the fish oil for cardiovascular upkeep.

100 mg morning with fat momentous
performance · cognition

Creatine Monohydrate

Most researched supplement in sports science. Strength, endurance, and — often underrated — cognitive benefits. Monohydrate is the form with the evidence behind it. Timing doesn't much matter; just take it daily.

5 g any time with food momentous
sleep · cognition

Magnesium L-Threonate

The L-threonate form specifically crosses the blood-brain barrier — regular magnesium glycinate doesn't. Sleep onset, sleep quality, and cognitive support. Taken at bedtime; noticeably different from cheap magnesium oxide.

3 caps (~145 mg) bedtime empty stomach momentous

software

Tools I open every day.

Not a comprehensive list of everything installed — just what I actually reach for.

AI assistant

Claude

Powers my entire personal OS. Morning briefs, daily dashboards, scheduled agents that write and update files automatically. I use the Cowork desktop mode for hours a day — it's the closest thing I've found to a genuine thinking partner that also executes.

knowledge base

Obsidian

Three years of notes in plain Markdown, stored locally on my machine. Health records, project docs, financial context, people layers — everything lives here. No cloud lock-in, no subscription required for the core product.

AI meeting notes

Granola

Joins meetings and generates structured notes automatically — work standups, doctor appointments, vet visits. The transcripts feed directly into my context management system. Replaced manual note-taking almost entirely.

docs + collaboration

Notion

Where team docs, product specs, and anything that needs sharing lives. My personal knowledge stays in Obsidian; anything cross-functional goes to Notion. The two-tool split has held up for years.

hardware

Gear that earns its place.

Physical things I'd buy again without hesitation.

primary device

iPhone

More computing happens here than on my laptop on most days. Tightly integrated with Apple Health — every data source feeds in automatically. The ecosystem lock-in is real, and for me the tradeoff is worth it.

health tracking

Apple Watch

Passive health data backbone — steps, resting heart rate, workout detection, sleep when I wear it. All flows into Apple Health and then into my daily dashboards. The always-on heart rate data alone is worth it.

passive tracking

Withings Sleep & Scale

Sleep tracking mat that goes under the mattress — no wristband needed. Body composition scale for weight + muscle/fat split. Both sync to Apple Health automatically. The best passive health data I've ever added; completely zero-friction.

vehicle

Tesla Model S

The car I've wanted for years and finally got. Dog Mode keeps Yumi comfortable while I run errands — and displays "My owner will be back soon" on screen so no one panics. Sentry Mode is genuinely great peace of mind. Software updates feel like getting a new car every few months.

smart home

Automation that earns its keep.

Three companies. Zero regrets. The bar is: does it actually run itself, or am I still babysitting it?

switchbot

Curtain Robot

Clips onto any curtain rod and automates open/close on a schedule. Wakes up with the sunrise without me touching anything — genuinely one of the most satisfying smart home purchases. Retrofit, no rewiring, no new curtains required.

Air Purifier

Runs on auto mode and adjusts fan speed based on actual air quality readings. Especially useful with a dog in the apartment. Integrates with the same SwitchBot hub as the curtains — one app for both.

govee

Govee Lighting

Ambient lighting that actually transforms a room. RGBIC strips behind the TV and shelf lighting synced to scenes and schedules. Much better price-to-vibe ratio than the competition. The app has more options than I'll ever use — in the best way.
