VitaChek-C Strips, 50 Test Strips

(1 review) Write a Review

Wondering if you get enough Vitamin C through diet and/or nutrient supplements? VitaChek-C strips have been exclusively created by Riordan Clinic for in vitro measurement of urine Vitamin C. Each bottle contains 50 test strips. Start by testing early in the day before eating or taking nutrients. Then test after breakfast and again in the afternoon. Test a final time right before bed. The test strips are designed to be a fast and simple way to check your nutrient levels of Vitamin C daily so that you can adjust your diet or nutrient regimen accordingly.

"Vitamin C is found in three pools, tissues, blood and urine. Vitamin C disappears from the urine early in blood or tissue depletion. Plasma levels fall next and tissue levels (such as in leukocytes and platelets) are the last to fall. The VitaCheck-C strip, on the color chart, reflects levels of vitamin C of 0, 5, 10, 20, 40, 50, and 100 mg/dL. The normal range of urine Vitamin C is greater than 20 mg/dL, and Dr. Riordan preferred levels above 40. A consistent urine Vitamin C of 20 mg/dL or lower may be trying to tell you something."
