What Is 4Life Transfer Factor KBU?
4Life Transfer Factor KBU is a urinary system supplement designed to support kidney function, bladder health, and urinary tract balance using botanical extracts and immune-support transfer factors.
4Life Transfer Factor KBU® is a dietary supplement formulated to provide comprehensive support for the urinary system — specifically the kidneys, bladder, and urinary tract — in both men and women. It combines two distinct functional systems in one formula: a multi-herb botanical complex targeting urinary health, and 4Life’s proprietary peptide complex designed to educate and balance immune system cells.
How KBU Differs from Basic Urinary Supplements
Unlike basic cranberry supplements or single-herb bladder products, KBU delivers four separate, purpose-built blends: the Transfer Factor® Blend, Bladder Support Blend, Kidney Support Blend, and pH Balancing Blend.
This layered, synergistic approach provides comprehensive urinary system coverage that a standard single-ingredient supplement cannot replicate. The formula is protected by U.S. Patents 6,468,534 and 6,866,868 covering the extraction and combination processes for its proprietary peptide complex.
KBU is a product of 4Life Research, manufactured by BioMedical Research Laboratories, LLC in Sandy, Utah, using quality ingredients sourced from around the world. It is available at Recs-Medix for delivery to Nigeria, the US, UK, Canada, EU, and Australia via DHL Express.
This is a dietary supplement, not a medicine. It is not intended to diagnose, treat, cure, or prevent any disease.
What Does 4Life Transfer Factor KBU Do?
KBU is formulated to support the body’s natural urinary system functions through a combination of botanical ingredients and immune-education molecules. Each component in the formula is selected for a specific functional role within the urinary system.
The Bladder Support Blend — featuring cranberry (Vaccinium macrocarpon), d-mannose, blueberry (Vaccinium spp.), and lingonberry (Vaccinium vitis-idaea) — is designed to help maintain a healthy bladder environment. Cranberry is one of the most widely researched botanical ingredients for urinary tract health, with evidence suggesting it may help support the natural barrier function of the bladder wall.
The Kidney Support Blend combines IP-6 (inositol hexaphosphate), chanca piedra (Phyllanthus amarus), juniper berry (Juniperus communis), dandelion (Taraxacum officinale), and varuna (Crataeva nurvala) stem bark extract. These herbs have a long history of use in traditional wellness systems to support healthy kidney filtration, fluid balance, and natural elimination processes.
The pH Balancing Blend — apple cider vinegar, sodium bicarbonate, potassium bicarbonate, and calcium carbonate — contributes to maintaining a healthy urinary pH environment, which is an important factor in urinary comfort and tract health.
Finally, the proprietary immune support blend (UltraFactor®, OvoFactor®, and NanoFactor®) provides immune system support at the cellular level, helping immune cells learn, respond, and maintain balance — particularly relevant given the immune component of urinary tract health.

Ingredient Authority: What Is Inside KBU?
4Life Transfer Factor® Blend — 100 mg
This proprietary blend is the defining feature that distinguishes KBU from ordinary urinary health supplements. It combines three components:
- UltraFactor®: A proprietary concentrate of ultra-filtered 4Life Transfer Factor® proteins and other peptides derived from cow colostrum.
- OvoFactor®: A patented concentrate of 4Life Transfer Factor® proteins and peptides derived from chicken egg yolk, protected by U.S. Patent 6,468,534.
- NanoFactor®: A proprietary concentrate of nano-filtered cow colostrum for enhanced bioavailability.
Transfer factors are small messenger molecules that help educate immune cells. Rather than simply stimulating the immune system, this proprietary peptide complex helps immune cells recognise threats and maintain appropriate balance — a more targeted approach than general immune-boosting supplements offer.
Bladder Support Blend — 1,050 mg
- Cranberry (Vaccinium macrocarpon) fruit powder and extract: One of the most extensively researched botanicals for urinary tract health. Cranberry’s proanthocyanidins are thought to contribute to a healthy bladder environment by supporting the natural barrier properties of the urinary tract lining.*
- D-Mannose: A naturally occurring simple sugar that is absorbed in the intestinal tract and excreted via the urinary system, where it may contribute to urinary tract health.*
- Blueberry (Vaccinium spp.) fruit: Rich in anthocyanins and polyphenols, blueberry contributes antioxidant activity that complements the urinary support profile of cranberry.*
- Lingonberry (Vaccinium vitis-idaea) fruit juice: A Nordic berry closely related to cranberry, containing similar proanthocyanidins and antioxidant compounds that further support bladder comfort.*
Kidney Support Blend — 580 mg
- IP-6 (Inositol hexaphosphate): A naturally occurring compound found in many plant foods, studied for its role in supporting kidney health and antioxidant function.*
- Chanca Piedra (Phyllanthus amarus) herb: A plant with deep roots in traditional Amazonian and Ayurvedic wellness practices. Its common name — “stone breaker” — reflects its traditional association with supporting the kidneys and urinary tract.*
- Juniper (Juniperus communis) berry: Traditionally used as a diuretic herb to support healthy fluid balance and kidney function. Juniper berry contributes to the cleansing character of the Kidney Support Blend.*
- Dandelion (Taraxacum officinale) aerial parts: Widely used in traditional herbal medicine as a mild diuretic and kidney tonic to support healthy elimination and fluid balance.*
- Varuna (Crataeva nurvala) stem bark extract: An Ayurvedic herb with a long history of use to support healthy kidney and bladder function, particularly in relation to urinary tract tone.*
pH Balancing Blend — 208 mg
Apple cider vinegar, sodium bicarbonate, potassium bicarbonate, and calcium carbonate work together to help maintain a healthy urinary pH environment — a practical addition that is rarely seen in standard urinary supplements.*

How to Use 4Life Transfer Factor KBU
Take four (4) capsules daily with 240 ml (8 oz) of water or other fluid. For best results, take two (2) capsules in the morning and two (2) capsules in the evening with meals. Each bottle contains 120 veggie capsules, providing a full 30-day supply at the recommended daily dose.
Do not exceed the recommended serving size. Store in a cool, dry place. Keep out of reach of children.
Best Results Routine
To get the most from 4Life Transfer Factor KBU, consistency is key. Follow these practical guidelines to build an effective daily routine:
- Morning (with breakfast): Take two (2) capsules with a full glass of water (240 ml). Taking with food may improve tolerance.
- Evening (with dinner): Take the remaining two (2) capsules with another full glass of water.
- Daily hydration: Adequate fluid intake — at least 1.5–2 litres of water per day — supports the urinary system independently and works in harmony with KBU’s botanical ingredients.
- Dietary support: Reduce high-sugar foods and highly processed ingredients that may place additional strain on the kidneys and bladder. A diet rich in vegetables and whole grains complements the supplement’s kidney-support herbs.
- Consistent daily use: Botanical supplements typically work best when taken consistently over several weeks. Allow at least 4–6 weeks of regular use before evaluating results.
Individual results may vary. Food supplements are intended to support a balanced diet and healthy lifestyle, not to replace them.
Who Is This Product For?
4Life Transfer Factor KBU is designed for adults who want to maintain urinary tract health as part of a proactive wellness routine. Typical user profiles include:
- Adults with a history of urinary discomfort: Those who experience recurring urinary tract discomfort and are looking for a preventive, daily supplement approach using evidence-supported botanicals such as cranberry and d-mannose.
- People over 40 concerned about kidney and bladder health: As the body ages, kidney filtration efficiency and bladder tone may naturally decline. KBU’s multi-blend approach addresses these concerns with a comprehensive, targeted formula.
- Health-conscious individuals seeking immune and urinary support together: Those who want the added benefit of 4Life’s proprietary Transfer Factor® Blend for immune system education alongside urinary health support — without taking two separate supplements.
- Men and women interested in natural kidney cleansing: People who prefer botanical approaches — dandelion leaf, juniper berry, chanca piedra — as part of a seasonal or ongoing wellness and natural elimination routine.
Who Should Avoid KBU or Consult a Doctor First?
- Pregnant or breastfeeding women: Consult your doctor or midwife before using this supplement during pregnancy or while nursing.
- People taking prescription medications: Some herbal ingredients — including dandelion and juniper berry — may interact with diuretics, blood pressure medications, or kidney medications. Always consult your healthcare provider if you are on regular medication.
- Individuals with known kidney disease or serious kidney conditions: Those with diagnosed chronic kidney disease (CKD) or other significant kidney pathology should not use urinary or kidney herbal supplements without explicit medical supervision.
- People with allergies to milk or egg: KBU contains ingredients derived from cow colostrum (milk) and chicken egg yolk. Individuals with dairy or egg allergies should avoid this product.
- Children under 18: This product is formulated for adults. Keep out of reach of children.
What 4Life Transfer Factor KBU Does Not Do
- KBU is not a medicine and is not intended to diagnose, treat, cure, or prevent any disease, including urinary tract infections (UTIs), kidney stones, or kidney disease.
- It is not a replacement for antibiotic treatment in cases of diagnosed bacterial urinary tract infections. If you have a confirmed UTI, seek medical advice and treatment promptly.
- It does not produce instant results. Botanical supplements work gradually over consistent daily use, typically over several weeks.
- It is not a substitute for adequate hydration. Drinking sufficient water daily is essential to urinary and kidney health and cannot be replaced by a supplement alone.
- It does not replace a balanced diet or healthy lifestyle. It is intended to complement, not substitute, good nutritional habits.
Storage and Safety
- Store in a cool, dry place away from direct sunlight and heat.
- Keep the container tightly sealed after each use.
- Do not refrigerate unless directed.
- Keep out of reach of children.
- Do not use if the seal is broken or missing upon receipt.
- Check the expiry date printed on the bottle before use.

Frequently Asked Questions About 4Life Transfer Factor KBU
What is 4Life Transfer Factor KBU used for?
4Life Transfer Factor KBU is a dietary supplement formulated to support healthy urinary tract function, kidney filtration, bladder tone, and fluid balance. It also includes the 4Life Transfer Factor® Blend to provide immune system education and support alongside urinary health benefits.*
How do you take KBU?
Take four (4) capsules daily with 240 ml (8 oz) of fluid. For best results, split the dose — two (2) capsules in the morning and two (2) capsules in the evening. One bottle provides a 30-day supply.
How does KBU differ from a basic cranberry supplement?
Basic cranberry supplements typically contain only cranberry extract as a single ingredient. KBU combines four distinct blends — a Bladder Support Blend (cranberry, d-mannose, blueberry, lingonberry), a Kidney Support Blend (chanca piedra, dandelion, juniper, varuna, IP-6), a pH Balancing Blend, and the unique 4Life Transfer Factor® Blend — providing far broader urinary system and immune support than a single-ingredient cranberry product can offer.
Is KBU safe for daily long-term use?
KBU is formulated with natural botanical ingredients and is intended for daily use. However, if you have a diagnosed medical condition — particularly related to the kidneys or urinary tract — or are taking regular medications, consult your healthcare provider before beginning any new supplement.
Does KBU contain allergens?
Yes. KBU contains ingredients derived from cow colostrum (milk) and chicken egg yolk. It is not suitable for individuals with confirmed dairy or egg allergies. The product label clearly states: “Contains ingredients from milk and egg.”
Can women take KBU?
Yes. 4Life Transfer Factor KBU is formulated for both men and women. Pregnant or breastfeeding women should consult their doctor before use.
How long does it take to see results?
Botanical supplement effects are gradual. Most users are advised to use KBU consistently for at least 4–6 weeks before assessing results. Individual results will vary depending on diet, lifestyle, hydration, and overall health.
Where can I buy 4Life Transfer Factor KBU in Nigeria, the UK, USA, or Canada?
4Life Transfer Factor KBU is available to order online at Recs-Medix Natural Solutions. We ship internationally via DHL Express to Nigeria, the United States, the United Kingdom, Canada, the EU, and Australia. You can also purchase in person at our Lagos, Abuja, or Jos stores.
Can KBU help with frequent urination?
KBU is formulated to support healthy bladder tone and urinary tract function — factors that can contribute to urinary frequency and comfort. Ingredients such as cranberry, d-mannose, and varuna stem bark extract have traditional associations with supporting normal bladder control and urinary comfort. KBU is a dietary supplement, not a treatment for any medical condition. If frequent urination is a persistent concern, consult a healthcare professional for an evaluation.*
