What Exactly is Juice Plus? A Whole Food Approach
Juice Plus+ is a dietary supplement derived from whole food-based ingredients, rather than being a synthetic multivitamin. It includes juice powder concentrates from 30 different fruits, vegetables, and berries, along with plant-based omegas. The produce is juiced, dehydrated into a powder, and then put into capsules or chewables to capture nutritional value like vitamins, antioxidants, and phytonutrients. Its core idea is to help fill the nutritional gap for those not consuming enough fruits and vegetables daily. However, it is meant to supplement, not replace, a diet rich in fresh produce.
Scientific Backing and Bioavailability
Juice Plus emphasizes its research portfolio, citing over 40 peer-reviewed scientific publications that examine its effectiveness and nutrient absorption (bioavailability). The company's cited studies indicate that Juice Plus can increase blood levels of key nutrients and antioxidants.
Key Benefits of Juice Plus
Clinical research has identified several areas where Juice Plus may offer benefits:
- Immune System: Studies suggest support for immune function.
- Cardiovascular Health: Research points to contributions to heart health, including maintaining healthy blood pressure and cholesterol already within a normal range, and supporting arterial elasticity.
- Antioxidant Protection: Increasing blood antioxidant levels helps protect against oxidative stress.
- Skin Health: Studies indicate potential improvements in skin hydration, thickness, and microcirculation in middle-aged women.
- Gum Health: Research suggests improved gum health when added to dental cleaning.
- Cognitive Function: One study showed improvements in working memory and processing speed in healthy young adults.
- Inflammation Reduction: Some studies suggest a decrease in biomarkers of systemic inflammation.
Juice Plus vs. A Standard Multivitamin
The fundamental difference between Juice Plus and a traditional synthetic multivitamin lies in the source and nature of the nutrients.
| Feature | Juice Plus+ (Whole Food) | Standard Multivitamin (Synthetic) |
|---|---|---|
| Source of Nutrients | Powdered concentrates of fruits, vegetables, and berries. | Lab-made, isolated chemical versions of vitamins and minerals. |
| Nutrient Complexity | Thousands of naturally occurring phytonutrients, antioxidants, and enzymes from whole foods. | A limited list of basic vitamins and minerals. |
| Bioavailability | Designed for high absorption, as the body recognizes nutrients from whole foods. | Absorption can be poor; nutrients may pass through the body unabsorbed. |
| Synergistic Effects | The blend of whole food compounds works synergistically, enhancing benefits. | Isolated nutrients lack the natural synergy found in whole foods. |
| Regulation | Regulated as a food product, with an NSF certification for purity. | Less stringent regulation; quality can vary widely. |
| Labeling | Contains a Nutrition Facts label, recognizing the product as food. | Features a Supplement Facts label, indicating isolated components. |
Potential Downsides and Considerations
While research is highlighted, some critics, such as those at McGill University's Office for Science and Society, point out that the dehydration process removes fiber, a crucial component for gut health. Additionally, some research has faced scrutiny regarding potential conflicts of interest. Consulting a healthcare professional before starting any new supplement is recommended.

Conclusion
Juice Plus vitamins are a whole-food-based supplement designed to supplement a diet with plant-derived nutrients. Research suggests potential benefits for the immune system, cardiovascular health, skin, and dental health. However, it does not replace a balanced diet of whole fruits and vegetables and lacks the fiber found in fresh produce. It should be seen as a complement to a healthy lifestyle, not a sole solution or substitute for proper nutrition.
