THE SELL: The DIY option. Register online for a one-time kit and receive a blood-spot card in the mail. Prick a finger and blot the five circles, then send back. Results are posted online in a week, minus any nutritional recommendations. The company also offers a monthly testing option to track biomarkers over time.
THE SELL: Face-to-face advice. Register online, have blood drawn at a clinic, and sit down for a 20-minute consultation with a health professional for answers to questions about nutrition and lifestyle.
THE SELL: Total customization. Pick a biomarker package and have your blood drawn. Results appear online about two days later, with detailed nutritional recommendations that account for food allergies and taste preferences.
