FunctionaLab Active Mix & Nutrient Tonics in Prophyto, Provita, and Energy
The claim: This white-tea-infused supplement program boosts energy for better workouts, while the low-calorie, antioxidant-rich tonics serve as pick-me-ups when you're fatigued.
The cost: $145 for a 30-day supply of pills; $4 for each tonic
MC Editor's verdict: By the end of the second week, our tester was waking up more easily and felt more robust when working out; by the end of the third week, she was hopping out of bed to get to the gym. She felt exhausted the fourth week but thinks her cardio overload is partly to blame. The tonics, though tasty, were no substitute for her afternoon coffee.
The expert says: "White tea is high in phytonutrients, which help our body function better, but it's a stretch to say they would improve workout performance. This mix also contains high doses of vitamins and minerals commonly found in multivitamins, so to prevent possible toxicity, it's best not to take any additional dietary supplement."
