Can I drink bottled juice during a fast?

Do not expect to heal your body drinking only bottled juices.  They lack in vitamins, minerals and enzymes.  Bottle juice is fine if you are only trying to lose weight and you can fast on it, but that is so much less than the incredible boost in health and vitality that juices from and extractor will give you. I do not recommend prolonged fasting on bottled, canned or frozen juices.  If you are going to fast that long, a juicer is a cheap investment and will transform your fast.

I only recommend bottle juices when you main juices are coming from an extractor and the bottle juices are a supplement.

Buy unsweetened natural juice is good since these has lower sugar levels. Bottled juice is great when you do not have fresh juice available, it is an alternative.  Also frozen concentrates are good. When I make fresh watermelon juice, I add a can of frozen pineapple juice and the taste is amazing and it also sustains me for many hours of hard physical labor.

Fresh juice is better for you as it has a revitalizing effect due to enzymes and all the nutritional mysteries that science is just beginning to understand that are killed by heat, air, and light. So drink as much fresh juice as you can and when you can’t drink sweetened herbal teas, bottled juice and frozen concentrates.

Bottled Juice Problems During a Fast

Too much acidic juice, such as apple or grapefruit take too quickly can cause stomach pains.

Heated tomato juice with some Worcestershire sauce and a sprinkle of garlic powder when you are chill from fasting is delicious and heart warming. Too much tomato juice slows the detoxification.

Freeze fresh cantaloupe juice into Popsicle and you feel like you are cheating because they taste so good. Enjoy as they are permitted during a juice fast.

Bottled juice is pasteurized and has lost its enzymes but has natural sugars, vitamins and mineral. Do not drink powdered juice mixtures or flavored fruit drinks.

My favorite bottle juices are beet, mango and pear.

    what about drinking V8? I don’t like normal V8 but I like V8 Splash, it is 10% juice. Would driking V8 splash be a good or bad idea durring a juice fast? Im going to start a week fast today. This will be my first one. Just kind of a trial.

    Hi Tim,
    I live in third world counties and the water is often loaded with bacteria. When the stomach starts to gurgle, I race to the pharmacy.

    Hi, I was thinking about fasting for my first time. I work at GNC and take a multivitamin and some extra antioxidants(alpha lipoic acid). I was wondering if it I could do the juice fast and continue to take my supplements at the same time.

  6. Tom Coghill says:

    Yes Shanna, It is always good to take supplements on a juice fast.

    You’re not supposed to do a bottled juice fast because like all cooked, canned or bottled food, it is devoid of “food enzymes” which make food far less nutritionally costly to process. I’ve only heard of food enzymes on TV once, during a Jack Lalanne commercial. Why? Because all brand name foods have no enzymes and all foods that have enzymes anyone can grow. Plus the more enzymes in fresh foods the shorter the shelf life. They’d lose money if we know about food enzymes.

    Just put a banana + water or some watermelon in the blender for your juice, maybe add some fiber supplement. Much healthier. Anyone not used to eating this healthy can expect withdrawal symptoms.

    I thought watermelon was not a good fruit to use in a juice diet?

    Hi Lisa,
    Watermelon makes lots of cheap delicious juice and excellent for juice fasting. I like it with pineapple.

    I am considering a juice fast for spiritual and overall health. I would like to lose weight as well and I am looking at a 30 day fast. I am a beginner when it comes to juice fasting and I am trying to find out as much as possible before I begin. I am currently cutting down my food consumption to prepare my stomach. I am limited to bottled juices and I am looking for suggestions as to which are the best. My current line of thinking lets me know that if it doesn’t contain corn syrup it can go on my list. Please help me with some information. If possible, can you email me at the address I have provided you.

    Hi Tom,
    I am thinking about doing the juice fast but a little scared because this is my first time but had a couple question. I am in a fitness class during the week is it ok to still fast? and can you make any kind of juice in the juicer(veggie vs fruit) whats best? Also how much weight does an average person lose? I am 148 and want to be at 130 :) how long would I have to fast? does it clean your system out should I stay close to the restroom? and lastly can I drink green tea with honey like the lipton brand? thanks hopefully I can do it!

      Yes you can exercise. Do a site search on exercise, weight loss rates, 30 days is recommended if you have will power and are without compulsive behaviors. If not shorter juice fast progressing to longer ones.

    When you fast, can you drink Coffee or Tea? What about Tang juice?

  18. AboutTime says:

    This is my first 30 days juice fast and I had bought v8 vegetable juice that should last me for a week. Are you suggesting that I should stop them completely and buy a juicer instead?

  19. Ron says:

    Hi About Time! You only get live enzymes from fresh juice. V8 tastes good, but you are getting too much salt and acid from tomatoes. Bottled or can juice is ok a few times a week if they are 100% pure, low on sugar (under 15grs) and sodium (140mgs). Get a juicer or you won’t get the full benefits of fasting, and actually prolong the detoxing process.

  20. AboutTime says:

    Ron, Thank you for your answer.
    Wow I am just amazed by how quick you answer, God bless your heart for even making this website free. Today is Day 2, and yesterday I read more articles on this website and realized that I do need to get a juicer for really; I thought I did not have time make fresh juice but I will make it happen.
    Thanks so much for the quick reply. May God continue to prosper you and the team.

    I found this bottled juice ‘CHARLIE’S’ which states it has no atificials for example the ingredients for the apple juice is simply – pressed apple juice, vitamin (C) and that it. I was wondering, could i fast on this type of bottled juice?

    • Ron says:

      Hi Libby, (My wifes name too!!) Bottled juices are ok. But we need live enzymes in fresh juices. Most enzymes have diminished within in 12 hours. I usually use bottled teas and juices as a supplement to my regular juicing. In a pinch, the bottled juices are fine. Just keep the sugar in the single digits of grams. I find there is way too much sugar in the bottled stuff. Hope this helped? Ron

  22. hanmin1 says:

    Will I have healing effect even if I drink juice from carton but take supplement (multivitamin & prebiotics)?

  23. Ron says:

    Hi hanmin1, Juice is best fresh. Live enzymes only live in foods for about 8 – 12 hours. You will still get vitamins and “maybe” some nutrients and minerals from store bought juices. But, you will usually get added sugar…and God knows what else. Bottled juice is better than cartons, and ok in a pinch. Try to get a juicer and drink fresh fruits and veggies when you can. Your body will thank you for it! Ron

    We have a nice twin gear juicer. I would like to know if i would loose a lot of the nutrition if i made a days worth a juice in the morning and kept it in the fridge. I would do it everyday so none would be around for more than 24 hours. Its time consuming preparing juice and cleaning the juicer multiple times a day. We are juicing all sorts of veggies.

  25. sarenee19 says:

    Hi Tom, I’m beginning a juice fast for the first time and I was wondering, are weight loss rates different depending on size? I weigh 130 lbs. and would like to go down to 100lbs, which my doctor says is healthy for my bone structure. How long do you think it will take to lose this amount? also, on the juice fast, should I drink more vegetable or fruit juice or both?
