“We don’t believe big pharma— and the synthetic ingredients it relies on— should be the single clinical nutrition option for patients.”


At CF Nutrition, we ask our team a simple question: “What kind of products would we want for ourselves or our loved ones if our bodies needed nutritional support?” Food is medicine…and processed, over-sweetened products full of synthetic additives and dirty fillers are far from food and even further from medicine. That’s why every ingredient we select has a purpose.

Taste isn’t everything, but without it a drink is nothing. If you can’t stomach the taste, you’ll never drink it. That’s why we carefully select natural flavors in our clinical nutrition to be enjoyed—not just tolerated.


In answer to the growing demand for natural products, CF Nutrition’s team of doctors, dietitians, and beverage scientists created a suite of clean, delicious alternatives to the synthetic drinks on the market today.

“The way of the future in pre-op care”

As a physician and surgeon myself, I wholeheartedly endorse this product. It is really the first of its kind in the US, and it has been a huge success in my experience. Not only do I use it for all of my own surgical patients, but I have used it as a patient myself before a procedure. It makes a tremendous difference. The drink actually tastes pretty good, especially chilled overnight, but the best thing is that you go into surgery without the starving or thirst feeling, and you are much calmer, more relaxed, and you get through it much better. I think this should be the way of the future for preop care. There is plenty of scientific evidence supporting its use; we just have to convince our anesthesiologists that it’s time to drop the “old school ways” of nothing to eat or drink after midnight, and adopt the new evidence-based practices.
