Can you do a juice fast with a Vitamix?

A juice fast, also known as a juice cleanse or juice detox, involves consuming only fruit and vegetable juices for a set period of time. Some people choose to do a juice fast for health reasons like weight loss or detoxification, while others do it for spiritual or religious purposes. Juice fasts typically last anywhere from 1-7 days.

Many people use high-powered blenders like the Vitamix to make juices for their fasts. But can you successfully complete a juice fast using only a Vitamix? Let’s take a look at the pros and cons of doing a juice fast with a Vitamix blender.

Pros of Using a Vitamix for a Juice Fast

There are some advantages to using a Vitamix blender for juicing during a fast:

  • Gets more nutrients from produce – The Vitamix is a powerful blender that can break down fruits and veggies on a cellular level, releasing more vitamins, minerals and phytonutrients compared to a regular juicer.
  • Uses the whole produce – Juicers extract the liquid from produce and leave behind the fiber. The Vitamix pulverizes everything, so you get the beneficial fiber too.
  • Versatility – The Vitamix can make smoothies, nut milks, soups, sauces and more. So you’re not limited to just juices.
  • Easy to clean – The Vitamix jug detaches and can be cleaned in the dishwasher. Juicers have more components to wash by hand.
  • Saves money – The Vitamix eliminates the need to buy a separate juicer appliance.

So using a high-powered blender like the Vitamix allows you to get more nutrients from your produce while retaining the fiber. And their versatility and easy cleanup makes the juicing process simpler.

Cons of Using a Vitamix for a Juice Fast

However, there are also some potential drawbacks to using a Vitamix blender for juicing during a fast:

  • Not as smooth – Juicers separate the fiber from the liquid, resulting in a smoother, drinkable juice. The Vitamix doesn’t remove fiber so juices may have a thicker, pulpy texture.
  • Sugar content – Blending keeps the sugars from whole fruits intact, while juicers allow you to remove some sugars by not including the flesh. Important to consider for longer fasts.
  • Oxidation – The high-speed blending of the Vitamix introduces air into juices, causing oxidation faster. Juices made with a cold-press juicer last longer.
  • Less variety – Some produce like wheatgrass and sprouts don’t juice well in a blender. So juice options may be more limited.
  • Tough on produce – The fast spinning blades heat up and can destroy delicate produce if blended too long. Juicers are gentler.

So in some cases, using a dedicated juicer may result in smoother, more nutrient-rich juices that last longer compared to the Vitamix. The lower speeds of a cold-press juicer also retain more enzymes.

Tips for Using the Vitamix for Juice Fasts

If you decide to use a Vitamix for your juice fast, here are some tips to get the most out of it:

  • Use cold water – Adding ice or cold water helps blend produce smoothly and prevents heat buildup.
  • Blend in stages – Don’t overblend.Pulse and blend in short intervals to preserve nutrients.
  • Strain for smoothness – For smoother juices without fiber, blend and then strain through a nut milk bag or cheesecloth.
  • Supplement with citrus – Add lemon, lime, grapefruit, etc. Their acidity helps extract more juice from produce.
  • Try different speeds – Experiment with different blade speeds to find what works best for different produce.
  • Make nut milks – Expand variety by making nut and seed milks like almond, cashew or hemp.
  • Use herbs – Herbs like parsley, cilantro and basil add flavor and nutrients.

Following these tips will help you get the most nutrition from produce, avoid oxidation, and expand the variety of juices and nut milks you can make in the Vitamix while fasting.

Sample Juice Fast Schedule with a Vitamix

Here is an example 3-day juice fast schedule using a Vitamix:

Day 1 Day 2 Day 3
Morning: Green juice made with kale, cucumber, celery, lemon, ginger and apple Morning: Beet, carrot, orange juice Morning: Green juice with spinach, parsley, cucumber, celery and lemon
Mid-morning: Chia seed pudding made with almond milk Mid-morning: Strawberry-banana smoothie Mid-morning: Mango lassi with mango, yogurt and almond milk

Afternoon: Pineapple coconut smoothie Afternoon: Green juice with kale, spinach, cucumber, celery and lemon Afternoon: Watermelon juice
Dinner: Cauliflower soup made with cauliflower, onion, garlic and nutritional yeast Dinner: Zucchini noodles with raw tomato sauce and basil Dinner: Celery juice

This sample schedule takes advantage of the Vitamix’s versatility to make a variety of juices, smoothies, nut milks and raw soups. It provides a diversity of nutrients from fruits, vegetables, nuts and seeds. Be sure to drink plenty of water in addition to the Vitamix drinks while fasting.

Should You Do a Juice Fast with a Vitamix?

In summary, it is certainly possible to complete a juice fast using only a Vitamix blender. The Vitamix allows you to unlock more nutrients from whole fruits and veggies compared to a regular blender. And its versatility means you can make smoothies, soups, nut milks and more to support your fast.

However, a proper juicer may still result in smoother, longer lasting juices. And lower speeds protect delicate nutrients better. So if you’re doing a longer fast, a juicer may be a better option. But for short 1-3 day fasts, the Vitamix can definitely get the job done!

As with any fast, be sure to consult your doctor first, especially if you have any underlying health conditions. And introduce solid foods slowly when breaking your fast. With proper precautions, using a Vitamix blender can help support you through a safe, healthy juice fast.


A Vitamix blender is a versatile tool that can be used to make a variety of juices, smoothies, nut milks and other drinks to support a juice fast. Its high-speed blades break down fruits and vegetables on a cellular level to unlock more nutrients. However, a proper juicer still produces smoother, longer lasting juices by separating the fiber from the liquid. So a juicer may be better for longer juice fasts.

The key is to use fresh, organic produce and blend at proper speeds for your chosen ingredients when using the Vitamix. With some adjustments, a Vitamix blender can be an convenient option for completing short juice fasts of 1-3 days in duration. Just be sure to consult your doctor before beginning any fast.
