Fuel Your Active Lifestyle

Active women lose iron through sweat, foot strikes during running, and menstrual blood loss. Iron is essential for carrying oxygen to your muscles. Women ages 19-50 need 18mg daily, but active women may need up to 18-27mg. Include heme iron sources like lean meat and poultry, plus plant-based sources like spinach and legumes, paired with vitamin C to enhance absorption.

Both timing matters. Before exercise: eat a light meal with carbs and protein 2-3 hours before, or a small snack 30 minutes before. After training: consume protein and carbs within 2 hours to replenish glycogen and initiate muscle recovery. A post-workout ratio of 3:1 carbs to protein is ideal. For morning workouts, even a banana with nut butter helps.

Nutrition needs fluctuate with your cycle. During the follicular phase (menstruation to ovulation), metabolism is lower; during the luteal phase (ovulation to menstruation), you may need 100-300 extra calories daily. Iron needs increase during menstruation. Consider tracking energy levels and adjusting carb intake accordingly. Magnesium-rich foods help manage symptoms during the luteal phase.

Women have less sweat capacity than men and may be more susceptible to dehydration. Drink 400-800ml of fluid per hour during exercise, depending on intensity and conditions. Include sodium in sports drinks to enhance fluid retention. Electrolyte intake becomes more important during longer endurance events. Start hydrating before you feel thirsty, and monitor urine color—pale yellow indicates good hydration.

Active women need 1000-1200mg of calcium daily plus adequate vitamin D for optimal bone health. Weight-bearing exercise strengthens bones, but nutrition is equally important. Dairy products, fortified plant milks, leafy greens, and canned fish with bones are excellent sources. Vitamin D (from sunlight, fatty fish, or supplements) helps calcium absorption. Low energy availability can compromise bone health, so ensure adequate overall calorie intake.
