Seed cycling is a practice of eating specific seeds during certain phases of the menstrual cycle to support hormone balance and menstrual cycle regulation. The seeds used in seed cycling are flax, pumpkin, sesame, and sunflower seeds. The menstrual cycle is divided into four interconnected phases: menstruation, follicular phase, ovulation, and luteal phase. Seed cycling advocates believe that some seeds promote estrogen production, while others support progesterone production, and rotating these seeds throughout the menstrual cycle can help regulate hormone dysfunction, resulting in more balanced hormones and fewer hormone-related symptoms like hot flashes, PMS, irregular periods, and PCOS. However, there is limited scientific evidence to support the effectiveness of seed cycling. While seed cycling alone is not a cure-all, it can be a gentle and natural way to support hormone balance when incorporated consistently with other hormone-stabilizing practices. It is important to note that the menstrual cycle varies among women, and seed cycling relies on the belief that most women have a 28-day cycle, which is not the case for most women. Women with irregular or absent cycles, menopause, or post-menopause can still try seed cycling by starting the seed cycle with any two weeks and then rotating.
