Use case
Stack Almanac for athletes
Optimise recovery, performance, and energy with data-driven supplement tracking and AI-powered recommendations.
Athletes take supplements seriously — creatine, electrolytes, protein, adaptogens, joint support, recovery aids. But most athletic supplementation is based on what a coach, podcast, or training partner recommended, not personal data.
Stack Almanac connects your supplement routine to your actual performance data. Wearable integration brings in sleep, HRV, resting heart rate, and activity levels — so you can see which supplements genuinely affect your recovery and performance, not what a study on untrained college students found.
The challenges
Too many supplements, no way to know what works
Serious athletes often take 10-20+ supplements. Creatine, beta-alanine, electrolytes, ashwagandha, omega-3, vitamin D, magnesium — the list grows. Without tracking, you're spending money on supplements that might not be doing anything for you specifically.
Recovery is hard to measure
You can feel when you're recovered, but subjective assessment is unreliable. HRV, resting heart rate, and sleep quality are better signals — but connecting those to your supplement routine requires consistent tracking.
Timing matters more for athletes
Pre-workout vs post-workout. Fasted training vs fed. Night before vs morning of. Supplement timing around training sessions significantly affects absorption and efficacy, but most athletes wing it.
Training phases need different routines
A heavy strength block has different supplement needs than a deload week or an endurance phase. Most trackers don't account for periodisation.
How Stack Almanac helps
Wearable integration
Connect Apple Health, Oura Ring, Whoop, or other devices. Steps, sleep hours, HRV, and resting heart rate feed directly into your personal insights. See whether ashwagandha actually improves your HRV on rest days, or if creatine correlates with better sleep quality.
Personal insights
Stack Almanac compares your energy, recovery, sleep, and focus scores on days you take specific supplements versus days you skip. After 3-4 weeks, you'll know which supplements are earning their place and which are dead weight.
Training-aware timing
Stack Almanac understands pre-workout, post-workout, and around-training contexts. It flags conflicts (don't take magnesium right before training — it can cause GI distress), suggests optimal windows, and helps you build a training-day routine.
Daily Score for consistency
Your Daily Score tracks how consistently you follow your routine. During a competition prep or training block, consistency matters enormously. The score helps you maintain discipline across weeks and months.
AI advisor for athletic supplementation
Ask the Almanac Advisor about training-specific questions: 'Should I take creatine on rest days?', 'What's the best electrolyte ratio for long runs?', 'Is beta-alanine working for me?' The advisor knows your training context, supplements, and personal data.
