Use case
Stack Almanac for women
The first supplement advisor built around female biology — cycle-aware timing, sex-specific dosing, and recommendations that adapt to your hormonal status.
Most supplement research is conducted predominantly on men. Dosing recommendations, timing suggestions, and "optimal" routines are designed for male physiology by default. For women, this means following advice that may be wrong — or at best, incomplete.
Stack Almanac addresses this directly. When your personal profile includes your sex, hormonal status, and cycle tracking preferences, every recommendation and insight is filtered through that context. The AI advisor knows that iron needs change with menstruation, that magnesium requirements shift across the cycle, and that perimenopause fundamentally changes the supplementation equation.
The challenges
Male-biased research and dosing
Clinical trials historically under-represent women. Standard supplement doses are often derived from studies on men, ignoring differences in body weight, hormonal metabolism, and absorption patterns.
Cycle-dependent needs are ignored
Supplement requirements change across the menstrual cycle. Iron needs spike post-menstruation. Magnesium and B6 become more important in the luteal phase. Most trackers and advisors treat every day the same.
Life-stage transitions change everything
Perimenopause, menopause, pregnancy, and breastfeeding each require fundamentally different supplement routines. Generic advice doesn't account for where you are in life.
Hormonal conditions affect supplementation
PCOS, endometriosis, thyroid conditions, and HRT all change what you should take, when, and how much. These interactions are complex and poorly addressed by standard recommendations.
How Stack Almanac helps
Cycle-aware tracking and recommendations
Opt into cycle tracking and Stack Almanac adjusts recommendations by phase. Follicular phase: prioritise iron replenishment post-menstruation. Luteal phase: increase magnesium and B6 for PMS support. Your personal insights show which supplements work differently at different times of your cycle.
Sex-specific dosing
The AI advisor applies sex-specific dosing guidelines. Iron recommendations differ dramatically between pre- and post-menopausal women. Creatine loading protocols account for lower baseline stores. Calcium and vitamin D recommendations shift with menopause.
Hormonal status awareness
Your personal profile captures hormonal status — regular cycle, irregular cycle, PCOS, perimenopause, menopause, HRT, or thyroid medication. The advisor tailors every response to your current reality, not a generic female template.
Cycle-phase insights
A unique feature: Stack Almanac compares your energy, mood, sleep, and focus by cycle phase. See whether magnesium helps more during the luteal phase. Discover if your B-complex makes a bigger difference follicular vs luteal. Personal data, tailored to your biology.
Medication-aware recommendations
If you're on hormonal contraception, HRT, thyroid medication, or other prescriptions, the interaction database flags conflicts and spacing requirements. The advisor knows to separate magnesium from levothyroxine by 4 hours, or to adjust vitamin K if you're on certain medications.
