Manda Hakko (万田発酵) has been producing fermented plant foods since 1969. We analyzed their MANDA CARE PLUS (Papaya + Cocoa flavor) to evaluate its claims about inner beauty and digestive health support.
What is MANDA CARE PLUS? This is a fermented food supplement containing 53+ types of fruits, vegetables, grains, and seaweeds that are naturally fermented and aged for over 3 years and 3 months. The papaya + cocoa version emphasizes papaya enzyme (papain) and cacao polyphenols as key functional ingredients.
The verdict? A traditional fermented food with potential benefits, but lacking scientific validation. While individual ingredients like papain and cocoa polyphenols have clinical support, this product uses a proprietary blend approach with no disclosure of active compound amounts. Without clinical trials on this specific formulation or standardized dosing information, you're relying entirely on traditional use rather than evidence-based efficacy.
Quick Summary
Uses proprietary blend approach with no disclosure of active compound amounts. Impossible to assess whether papain or polyphenol levels are clinically meaningful.
MANDA CARE PLUS combines ingredients with legitimate scientific support (papain, cocoa polyphenols, fermented foods), but the product itself has never been clinically tested. The proprietary blend approach means you don't know if you're getting meaningful amounts of active compounds.
Fermentation may enhance nutrient bioavailability, but without standardized amounts, actual absorption of active compounds is unknown.
Generally safe as a traditional fermented food. Main concerns are allergen exposure from 53+ ingredients and potential drug interactions with papain.
Ingredient Breakdown
This product contains 53+ plant ingredients including papaya (with papain enzyme), cocoa (with polyphenols), fruits, grains, vegetables, and seaweeds. The challenge is that none of the active compounds are quantified, making it impossible to compare against clinically effective doses.
Primary Ingredients
Papaya (Papain Enzyme)
Digestive Enzyme / Protein Digestion
Papaya contains papain, a proteolytic enzyme that breaks down proteins into smaller peptides and amino acids. Clinical studies using concentrated papaya preparations (like Caricol) showed improvements in IBS symptoms, constipation, and bloating after 40 days. In trials with 150+ participants, papaya enzyme reduced digestive discomfort and inflammation. However, MANDA CARE PLUS does not disclose how much papaya or papain it contains, making it impossible to know if the amount is clinically relevant.
Cocoa Polyphenols
Antioxidant / Cardiovascular Support
Cocoa is rich in polyphenols (catechins, anthocyanins, proanthocyanidins) with potent antioxidant activity—2-5x higher than green or black tea. Clinical trials show cocoa polyphenols support cardiovascular health, reduce inflammation, lower blood pressure, and improve endothelial function. Studies typically use 200-900mg of cocoa flavonoids daily. Without knowing the cocoa powder amount or polyphenol content in this product, efficacy cannot be assessed.
Fermented Plant Complex (53+ ingredients)
Microbiome Support / Digestive Health
The product contains 53+ fermented ingredients including fruits (apple, persimmon, banana, pineapple, grapes), grains (rice, barley, millet), vegetables (carrot, garlic, burdock), seaweeds (kelp, wakame, nori), and others, fermented for 3+ years. A Stanford clinical trial found fermented foods increased microbiome diversity and reduced inflammation markers—but participants consumed high amounts daily (6+ servings). This product provides 2.5g per serving, which is minimal compared to clinical studies that used 75g+ of fermented foods like sauerkraut. The fermentation process may enhance nutrient bioavailability, but without clinical data on this specific formulation, benefits are theoretical.
Practical Recommendations
- Understand What You'Re Buying: This is a traditional fermented food product, not a standardized supplement. Think of it like consuming miso or kimchi—potentially beneficial, but without precise dosing.
- Consider Targeted Supplements: For digestive support or antioxidants, consider supplements with standardized amounts of papain or cocoa flavonoids that match clinical research.
- Watch For Allergens: With 53+ ingredients including nuts, fruits, and grains, check the complete ingredient list carefully if you have food sensitivities.
- Set Realistic Expectations: Benefits from fermented foods typically emerge from consistent, long-term consumption as part of an overall healthy diet—not as a quick fix.
Is it Safe?
The product consists of naturally fermented plant foods with a long history of traditional use in Japan. While generally safe for most people, the lack of ingredient standardization means effects may vary between batches. The extensive ingredient list also increases the risk of allergen exposure.
Safety & Considerations
- Proprietary Blend Concerns: The product does not disclose amounts of individual active compounds (papain, polyphenols, probiotics). This makes it impossible to assess whether you're getting clinically effective doses or to compare batches for consistency.
- Allergen Risk: Contains 53+ ingredients including: nuts (walnuts), fruits, grains, soybeans, sesame, and seaweeds. High risk for individuals with multiple food allergies or sensitivities. Always review the complete ingredient list.
- Papain Interactions: Papaya enzyme may interact with blood thinners (warfarin) and diabetes medications. Those with latex allergies should avoid papain. Pregnant or nursing women should consult healthcare providers.
- No Clinical Validation: While individual ingredients have research support, this specific product formulation has not been clinically tested. Benefits are theoretical based on traditional use and ingredient profiles.
- Traditional Food Vs. Supplement: This is a fermented food product rather than a standardized supplement. Effects may vary between batches due to natural fermentation variability.
The Science
The individual ingredients—papaya enzyme, cocoa polyphenols, and fermented foods—have legitimate clinical support. However, this specific product has never been clinically tested. Without knowing the amounts of active compounds or seeing human trial data on MANDA CARE PLUS itself, any efficacy claims are speculative.
