Women are not small men. During our menstrual cycle our internal temperature varies by 0.5°C, while our sodium losses increase and plasma volume drops. Dr. Stacy Sims developed Active Hydration for Women to address these physiological realities to help female athletes:

• Increase Power Output
• Improve Endurance
• Avoid Premenstrual-Related Performance Decline

Get the nutrition that matches your physiology and see how much better you feel and perform.

Two SaltStick Caps in an hour equate to 430 mg sodium, 126 mg potassium, 22 mg magnesium, and 44 mg calcium per hour: The ideal ratio to keep you moving. SaltStick Caps have been formulated to provide your body with a balanced electrolyte content in the suggested serving of 1 capsule per 30-60 minutes. 

As women, our recovery physiology is heavily influenced by our menstrual cycle. Recovery is critical for us because progesterone and estrogen inhibit muscle repair and glycogen restoration.

Acute Recovery for Women was developed to address these physiological realities. It helps female athletes:

• Promote Muscle Synthesis
• Reduce Hormonal Influences on Recovery
• Optimize Training Adaptations

That's why the scientists at First Endurance developed Ultragen, the most advanced post-recovery formulation ever produced. Each serving of Ultragen delivers the levels of nutrients that have been shown in clinical research to maximize recovery and give you an extra edge over the competition.
