The wellness market has seen a surge in "period-friendly" drinks, with brands claiming their concoctions can alleviate common menstrual symptoms like cramps, bloating, and mood swings. These beverages fall under the umbrella of functional beverages, designed to offer benefits beyond hydration through added ingredients such as vitamins, minerals, and herbs.
Some of these ingredients have scientific backing for their potential effects. According to registered dietitian Janelle Connell, chaste berry, ginger, and lemon balm stand out. Research suggests chaste berry may help with PMS symptoms including breast tenderness, headaches, irritability, and mood swings. Ginger, known for its anti-inflammatory properties, might aid in reducing cramps, nausea, and bloating, with one study indicating it could be as effective as ibuprofen for menstrual pain. Lemon balm is thought to support mood by increasing GABA levels in the brain, a neurotransmitter associated with calmness.
Other ingredients found in these drinks, such as dong quai, white peony, Chinese licorice root, and Siberian ginseng, are more rooted in traditional medicine than extensive modern clinical trials for PMS specifically, notes registered dietitian Sydney Lappe. Chamomile, fennel, cinnamon, and turmeric also show some promise for symptoms like cramping, inflammation, and mood changes, though research remains limited. Raspberry leaf, motherwort, and nettle leaf have historical uses for cramps and heavy bleeding, but high-quality human studies are scarce.
However, experts caution that the effectiveness of these drinks can be limited by ingredient dosages. Dr. Sheryl A. Ross, an OB/GYN, points out that the amount of beneficial ingredients in many products may not be sufficient to significantly impact disruptive period symptoms. A small amount of ginger or magnesium, while promising on a label, might not provide the same effect as the quantities used in studies.
Potential pitfalls also exist. While most ingredients are likely safe for healthy adults, "natural" does not always mean harmless. Dong quai, for instance, contains compounds that can thin the blood, potentially increasing menstrual flow. Some formulas include iron, which, while important for some menstruating individuals, can cause constipation and gastrointestinal distress if taken unnecessarily. Herbs like chaste berry, licorice, and ginseng may interact with hormonal pathways and warrant caution for those on hormonal medications or managing hormone-sensitive conditions.
Experts also warn against "supplement stacking," where combining multiple PMS products could lead to unintentionally high doses of certain ingredients. A significant concern is when products list ingredients as "proprietary blends" without specifying individual dosages, making it impossible for consumers to know what they are actually consuming.
While period drinks might offer some convenience, health professionals emphasize that foundational lifestyle habits are the most effective strategies for managing menstrual discomfort. Regular exercise, consistent sleep, stress management, and a nutrient-rich diet can all contribute to easing symptoms like fatigue, bloating, and mood changes. Consulting a healthcare provider to rule out underlying conditions is also recommended over blindly treating symptoms. For more severe symptoms, conventional treatments like NSAIDs, SSRIs, or birth control pills, combined with healthy lifestyle choices, are likely to provide more substantial relief than functional beverages alone. Ultimately, these drinks are best viewed as a potential supplementary tool rather than a definitive cure for monthly misery.
