What Is a 28 Day Juice Cleanse and How Does It Work
A 28 day juice cleanse is an extended dietary protocol where participants consume only fruit and vegetable juices for four weeks, replacing all solid meals. Programs typically deliver 4 to 6 cold-pressed juices per day, totaling roughly 1,000 to 1,500 calories daily. The cleanse relies on pre-packaged bottles shipped to subscribers, with brands such as Blueprint Cleanse, Pressed Juicery, and Liquiteria offering structured 28 day programs that include morning celery juice, midday green blends, and evening nut-milk-based elixirs. Industry reports indicate that extended cleanses now represent a growing segment of the functional beverage market, with companies expanding subscription tiers to accommodate 21 and 28 day durations.
Most 28 day juice cleanse programs cost between $600 and $2,500 per cycle, depending on brand, delivery frequency, and ingredient complexity. Higher-end cleanses from brands like Kreation Organic and Sakara Life can exceed $300 per day, while standard cold-pressed offerings from local juiceries often fall below $150 per day. The extended duration raises concerns about nutrient adequacy, as juice-only diets typically lack protein, healthy fats, and fiber. Registered dietitians note that prolonged cleanses may lead to muscle loss, electrolyte imbalances, and gastrointestinal discomfort, especially for individuals with pre-existing metabolic conditions.
28 Day Juice Cleanse Market Leaders and Pricing Trends
In the U.S. juice cleanse market, companies such as Suja Juice, Daily Harvest, and Freshly have expanded into extended cleanse offerings, with 28 day programs priced between $800 and $1,800. Blueprint Cleanse, one of the earliest pioneers, offers a 28 day plan starting around $1,200, which includes organic cold-pressed juices and optional add-ons like adaptogen shots and probiotic blends. Forbes data shows that the U.S. cold-pressed juice market reached over $10 billion in annual retail sales by 2024, with cleanse subscriptions growing at double-digit rates year over year.
Subscription models dominate the 28 day juice cleanse space, with most companies requiring full upfront payment or auto-ship commitments. Some brands offer tiered pricing based on calorie density and ingredient sourcing, while others bundle coaching, email support, and progress tracking into the package. The competitive landscape has intensified as wellness startups and established beverage companies enter the space, leading to more standardized pricing and wider availability through third-party retailers and e-commerce platforms. SEC filings from publicly traded beverage and wellness companies show increased capital allocation toward cold-pressed and functional juice product lines.
Health Risks, Scientific Evidence, and Practical Considerations
Medical literature consistently warns that a 28 day juice cleanse poses risks including hypoglycemia, kidney stress from high oxalate intake, and inadequate protein for immune function. The American Heart Association and Mayo Clinic advise against prolonged juice-only diets, noting that whole fruits and vegetables provide fiber and satiety that juice lacks.
