Symptoms of food sensitivity include: irritable bowel syndrome, joint pain, chronic headaches, migraines, fatigue, eczema, and psoriasis to name a few. These symptoms generally occur days after the food is ingested which makes the offending food hard to identify without proper testing. Test, Don't Guess! The FIT test is a patented multi pathway delayed food sensitivity test. This new technology measures both IgG and Immune Complexes, the most common food-related pathways in the body. The test comes with a free wellness consultation with our clinical pharmacist. Available for ages 2 years and up!
