Understand and optimize your immune health
The diagnostic kit
Most of us don't get enough vitamin D to fulfill our body’s needs. The d.velop™ vitamin D test kit 2-pack, available for free with a three-month subscription (a $100 value), will help you first understand your current vitamin D deficit, and then track your progress as you reach recommended levels — which can happen in as few as 14 days.
The d.velop™ app
Along with our exclusive d.velop™ formula that helps you achieve optimal vitamin D levels, you get the d.velop™ app free. The app provides you with actionable information to help understand your immune health with a holistic immunity score. And, it helps you address other potential immunity gaps based on your lifestyle, including nutrition, sleep, and environmental factors. It makes it easy to track your progress toward a healthier immune system. It is also supported by live coaching from registered dietitians, available to answer your questions and help ensure you achieve your goals.
