Can you use bottled lemon juice for the Master Cleanse?

The Master Cleanse, also known as the Lemonade Diet, is a liquid fast that involves drinking 6-12 glasses per day of a lemonade mixture for a period of 10 or more days. The lemonade consists of water, lemon juice, maple syrup and cayenne pepper. It was created by Stanley Burroughs in the 1940s and was popularized by Peter Glickman’s book “Lose Weight, Have More Energy and Be Happier in 10 Days”.

The Purpose of the Master Cleanse

The purpose of the Master Cleanse is to detoxify and cleanse the body while providing minimal nutrients and calories. Proponents claim it can remove toxins and impurities, eliminate cravings, clear the mind, improve digestion and promote weight loss. However, there is limited scientific evidence to support these health claims.

During the cleanse, only the lemonade drink is consumed for a period of at least 10 days. After this fasting period, you slowly reintroduce solid foods into your diet. The Master Cleanse is intended to give your digestive system a rest while flooding your body with nutrients from the lemonade.

The Role of Lemon Juice in the Master Cleanse

Freshly squeezed lemon juice is a key ingredient in the Master Cleanse lemonade recipe. Lemon juice has an alkalizing effect on the body and boosts levels of antioxidants, vitamin C, B vitamins and minerals. Lemon juice also aids digestion and is thought to help stimulate the release of toxins from the body.

In the classic Master Cleanse recipe, juice from at least 6-12 fresh lemons is recommended per day. The acidity of the lemon juice combined with cayenne pepper and maple syrup is intended to gently stimulate the stomach, liver and digestive system.

Can You Substitute Bottled Lemon Juice?

The Master Cleanse recipe was formulated around using the juice from fresh lemons. However, some people wonder if bottled lemon juice can be substituted in order to make the cleanse more convenient.

Unfortunately, most health experts advise against using bottled lemon juice for the Master Cleanse. Here’s why:

  • Bottled lemon juice is pasteurized and manufactured using heat and preservatives that destroy nutrients and enzymes naturally found in fresh lemons.
  • The bottling process oxidizes the lemon juice, altering its flavor and nutrient profile.
  • Freshly squeezed lemon juice has more vitamin C, antioxidants and beneficial plant compounds compared to bottled juice.
  • Bottled lemon juice frequently contains added sugars or flavorings, whereas the Master Cleanse requires pure, unsweetened lemon juice.
  • The flavor and acidity of bottled lemon juice is different than that of fresh squeezed juice.

For best results, use organic lemons and squeeze them by hand or with a manual citrus juicer. The fresher the lemon juice, the better it will perform for detoxification.

Tips for Preparing Fresh Lemon Juice for the Master Cleanse

Here are some tips for getting the most from lemons when doing the Master Cleanse:

  • Always use fresh, organic lemons when possible.
  • Wash lemons thoroughly before juicing.
  • Use lemons at room temperature for maximum juice extraction.
  • Roll lemons on the counter before juicing to help release more juice.
  • Use a manual or electric citrus juicer for easy juicing.
  • Juice lemons as needed, or juice ahead and store lemon juice in the fridge for up to 24 hours.
  • Measure out exact juice portions for each lemonade using a measuring cup.
  • Combine lemon juice with purified or spring water, maple syrup and cayenne pepper to make the lemonade.
  • Drink lemonade with a straw to prevent damage to tooth enamel from acidity.

How Much Lemon Juice Do You Need?

The minimum amount of lemon juice required per day on the Master Cleanse is from 6-8 lemons. However, Stanley Burroughs recommended using 12 or more lemons per day for maximum cleansing effects. The amount of lemon juice you need depends on:

  • Your desired calorie intake – the more lemonade you drink, the higher quantity of lemons required.
  • Your body size and metabolism.
  • How strictly you follow the cleanse. Consuming extra fluids, herbal teas or smoothies with the lemonade requires more lemon juice to compensate.
  • Your personal taste preferences and sensitivity to acidity. Adjust lemon quantity to suit your taste buds.

Most Master Cleanse guides suggest starting with a minimum of 6 lemons (approx. 1⁄2 cup juice per lemon) and increasing up to 12 lemons if tolerated. Here is an approximate lemon juice requirement per day:

Number of Lemons Approx. Lemon Juice Volume
6 lemons 3 cups
8 lemons 4 cups
10 lemons 5 cups
12 lemons 6 cups

Measuring Out Lemon Juice Accurately

To make the Master Cleanse lemonade, you’ll need to measure out exact quantities of lemon juice per serving. Here are some key tips for measuring lemon juice correctly:

  • Use a measuring cup for accuracy. Don’t estimate!
  • Squeeze lemon juice into a measuring cup before pouring into lemonade.
  • Remove pulp and seeds using a sieve or cheesecloth if desired for smooth consistency.
  • Pour in enough juice to reach desired measurement – 2 Tbsp or 1/4 cup per serving.
  • Adjust lemon juice amount gradually over the cleanse based on your changing taste preferences.
  • Record the number of lemons and volume of juice used each day to track your intake.

Precisely measuring your lemon juice avoids the risk of using too much or too little for the cleanse to be effective. Adjust lemon quantity based on your body’s reaction over 10-40 days.

Can You Add Too Much Lemon Juice on the Master Cleanse?

Is there any danger to adding too much lemon juice to the Master Cleanse recipe? A few precautions apply:

  • Risk of acidity: Excess lemon juice can make the lemonade very acidic for your teeth enamel and digestive tract.
  • Blood sugar impact: Large amounts of lemon juice can potentially cause blood sugar spikes and drops.
  • Side effects: Too much lemon juice could lead to diarrhea, reflux, bloating, nausea or headaches in some people.

That said, there is no universal upper limit to the lemon juice quantity you can tolerate. Some cleansers use as much as 1 cup per serving successfully. Increase lemon juice incrementally and listen to your body’s signals.

Adapting the Master Cleanse Recipe

The original Master Cleanse recipe called for fresh lemon juice as the only citrus ingredient. However, some cleansers adapt the recipe based on personal tolerance, availability and convenience. Common substitutions include:

  • Lime juice: 1-1 replacement for lemon juice.
  • Grapefruit juice: Adds sweetness and offsets lemon flavor.
  • Orange juice: Mixes well with lemon but decreases acidity.
  • Lemon-lime soda: Use only as flavor enhancer in very small amounts.

When substituting or adding juices, aim for 50-80% lemon juice in the recipe and adjust other ingredients accordingly. Keep total sugar content moderate by reducing maple syrup. Only fresh citrus juices are permitted – no bottled juices.

Should You Strain the Lemon Pulp?

For smoother texture, some cleansers prefer to strain the lemon pulp and seeds from the juice through a sieve or cheesecloth. However, the lemon pulp contains beneficial fiber and nutrients. Leaving pulp in the juice is perfectly fine and more nutritious.

If you do wish to strain, press the pulp firmly before discarding to extract as much juice and nutrients as possible. Don’t let good lemon flesh go to waste!

Tips for Handling Lemon Juice

Here are some final tips for handling lemon juice properly when doing the Master Cleanse:

  • Wash hands and equipment thoroughly before and after juicing.
  • Use only heat-sterilized glass jars or bottles to store lemon juice.
  • Keep lemon juice refrigerated and use within 24 hours for food safety.
  • Consume the juice immediately after mixing each serving of lemonade.
  • Discard any leftover diluted lemonade – don’t save it after drinking.
  • Stay hydrated by drinking plenty of water in addition to the lemonade.


While bottled lemon juice is more convenient, fresh lemon juice is strongly recommended for the Master Cleanse. Real lemons provide higher vitamin C and antioxidant levels and have a clean, pure taste. Investing in fresh organic lemons will make the cleanse more rewarding and effective. Measure the juice accurately, start with 6 lemons per day and slowly work up. Listen to your body, be consistent, and the Master Cleanse lemonade will yield results.
