• FULL VIEW OF FOOD INTOLERANCE & ENVIRONMENTAL SENSITIVITIES. This pairing helps you see how your body responds to everyday foods and the exposures in your surroundings. Looking at both together gives you clearer direction for meaningful changes instead of guessing what may be contributing to discomfort.
• FOUNDATIONAL FOOD INTOLERANCE INSIGHT. The Food Intolerance Test evaluates common ingredients across categories like proteins, grains, dairy, fruits, vegetables, and fats. Your results show which foods may be creating digestive stress so you can build a structured elimination and rotation plan.
• CLEAR ENVIRONMENTAL SENSITIVITY INSIGHT. The Environmental Intolerance Test screens common exposures in your home and daily routine, including fabrics, molds, dust, chemicals, and outdoor elements. Seeing your sensitivity response levels helps you make intentional adjustments that support your overall balance.
• FAST & SIMPLE HAIR SAMPLE PROCESS. Register your kit online, collect 10–15 strands of hair, and send them to our certified U.S. lab using the prepaid mailer. Your results arrive within days and are organized into clear response categories so you know what to reduce, rotate, or keep.
