What is cycle‑specific supplementation and how do I do it?

  • Article: How to Sync Your Routine With Your Menstrual Cycle

  • Expert: Dr. Caitlin O'Connor, ND 

  • Answer: Cycle-specific supplementation means adjusting your nutrition and supplements to match the changing needs of each menstrual cycle phase. Dr. Caitlin O'Connor explains that during menstruation, "focus on iron-rich foods" like "spinach, red meat, broccoli, legumes, pumpkin seeds, quinoa, tofu, and dark chocolate" to replace iron lost during bleeding. During the follicular phase and ovulation, your body is more efficient at burning fat, making it ideal for "slow-absorption carbs like brown rice, legumes, lentils, and fiber-rich fruit." In the luteal phase, Dr. O'Connor notes that "folks are naturally hungrier during this phase" because "their body is trying to signal to them that they need to increase their caloric intake to fuel the building of the uterine lining," requiring "more protein and complex carbohydrates." Perelel's Women's Daily Vitamin Trio provides comprehensive daily nutrition that adapts to your changing needs throughout your cycle, supporting energy metabolism, mood, immunity, and beauty—perfect for consistent baseline support while you customize your cycle-specific nutrition.
