VITA-Sorb is a liquid vitamin given once every 10-14 days. With this product, vitamins pass from the esophagus directly to the lymphatic system, by-passing the digestive system and then entering directly into the blood stream. University of Michigan research shows that blood levels can be spiked in as little as 30 minutes. Easily absorbed high levels are formulated to enhance the immune & reproductive system. This is a cross species product. Vita-sorb is a fat soluble vitamin blend rich in A, D, E and B-vitamins absorbed through the esophagus, traveling directly to the blood stream, rather than thru the digestive tract or by injection. Suggested feeding rate: 1 ml (1/5 tsp.) per 25 pounds of body weight.
