Do vitamins disappear after juicing?

Juicing fruits and vegetables is a popular way to get more nutrients into your diet. However, some people wonder if the vitamins and minerals are lost during the juicing process. This article explores whether juicing causes a loss of vitamins, the factors that affect nutrient levels, and tips for getting the most nutrition from your juice.


With the rise of juice bars and home juicing machines, drinking fresh juice has become a trendy way to increase fruit and vegetable intake. Proponents claim that juicing is better than eating whole produce because it removes fiber, allowing you to consume a higher concentration of vitamins, minerals, and antioxidants.

However, critics argue that important nutrients are lost in the juicing process. Some sources claim that juicing strips away up to 90% of vitamins and minerals. So what’s the real story?

This article will examine what happens to vitamins when fruits and vegetables are juiced. We’ll look at factors like heat exposure, oxygen, and fiber removal that can affect nutrient levels. You’ll learn which vitamins are most sensitive to juicing and get science-backed answers to questions like:

  • Does juicing destroy nutrients?
  • Are some vitamins completely lost?
  • How much of each vitamin is retained?
  • What can you do to maximize nutrition when juicing?

Let’s explore how juicing impacts vitamins and find out if those nutrients really disappear.

The Effect of Juicing on Vitamins

There are two main ways that juicing can reduce vitamin levels:

  1. Oxidation – Exposure to light, heat, and air can degrade delicate vitamins.
  2. Fiber removal – Some vitamins are bound to plant fibers which are lost in the juicing process.

However, the idea that juicing destroys all or even most nutrients is exaggerated. With minimal heat and oxygen exposure, many vitamins are retained. The extent of nutrient loss depends on the specific vitamin as well as juicing methods.
