MK WORLD / MK8
MK8 is an everyday body-care product for people interested in kidney health.
When learning about MK8, you can also use the kidney self-check to reflect on your health concerns.
Kidney self-check ↗01 / Who is it for?
Late nights, long hours sitting or putting off bathroom breaks? Reviewing daily habits is a starting point for kidney-health awareness. Do you recognise any of the following habits?
Persistent sleep loss may affect blood pressure and metabolism, which matter for kidney health.
Some medicines can harm the liver or kidneys with prolonged, excessive or inappropriate use. Follow monitoring advice and do not stop prescriptions on your own.
A high-salt diet can raise blood pressure. Excess added sugar can undermine weight and glucose control, indirectly increasing kidney risk.
Notice whether work or a busy schedule often makes you delay bathroom breaks.
Adjust sexual activity if it causes fatigue or disrupts rest. Frequency alone does not establish kidney damage.
Some supplements may harm the kidneys when overused or used inappropriately; risk depends on ingredients, dose and existing kidney function.
Stress can stimulate cortisol release from the adrenal cortex. Persistent stress may affect blood pressure, metabolism and immune regulation.
Extreme or unaccustomed exertion, especially with heat or dehydration, can trigger rhabdomyolysis and, in severe cases, acute kidney injury.
These prompts support reflection on daily habits. Some unhealthy habits may increase kidney-health risks over time; individual risks vary and this list cannot assess kidney function.

Glomeruli filter blood; tubules reabsorb and secrete substances. Waste leaves in urine.
Regulate water, electrolytes and acid–base balance.
Support blood-pressure regulation, red-cell production and bone health.
Remove urea and other wastes, including some drug metabolites.
Retain needed water and remove excess fluid.
Release erythropoietin to stimulate red-cell production in bone marrow.
Influence blood pressure through fluid balance and hormonal pathways.
Regulate sodium, potassium and other minerals for nerve and muscle function.
The kidneys also help activate vitamin D and regulate calcium and phosphorus for bone health.
These are possible effects, not inevitable outcomes or a checklist for self-diagnosis.
Schematic locations; some systems extend throughout the body
Seek prompt medical care for markedly reduced urine, breathing difficulty, chest pain or altered consciousness.
02 / What care needs does it address?
Five signs to watch for: foamy urine, swelling, high blood pressure, anaemia and fatigue.
Persistent foamy urine may be related to protein in the urine or other causes. A urine test is needed to check.
Swollen ankles, legs or eyelids may reflect fluid retention. Skin that stays indented after pressure also deserves attention.
High blood pressure can both damage the kidneys and result from kidney disease. Persistent or difficult-to-control readings need assessment.
Reduced kidney function may lower erythropoietin production, leading to anaemia with paleness, dizziness or weakness.
Persistent tiredness may relate to anaemia, waste buildup or sleep problems. Fatigue alone does not mean kidney disease.
Early kidney disease may have no obvious symptoms. These signs can have other causes and need assessment with blood and urine tests.
MK8 Kidney Cellular Nutrition Spray is an externally applied body spray. Brand materials describe natural trace-element compounds, no added alcohol or preservatives, and a water-treatment process called Quantum Molecular Band Processing Technology.
Read the label and intended uses without equating an external spray with kidney treatment.
Pay attention to regular sleep, suitable activity and scheduled health checks.
Use the kidney self-check to organise questions for a clinician. A questionnaire cannot measure kidney function.
03 / Design & formulation
MK stands for Molecular Key. According to the brand materials, MK8 contains naturally sourced trace-element compounds without added alcohol or preservatives. It is a body spray for daily external care.
MK8 enhances zinc, manganese, selenium, potassium, calcium and cobalt in its water-based formulation.
Supports protein and DNA synthesis, cell division and normal wound healing.
Acts as an enzyme cofactor in nutrient metabolism and antioxidant defence.
Forms part of selenoproteins involved in protection against oxidative damage.
Supports intracellular fluid balance, nerve signalling and muscle contraction.
Contributes to cell signalling, nerve transmission and muscle contraction.
Is part of vitamin B12, which supports DNA synthesis, blood-cell formation and nerve function. These roles cannot be attributed to cobalt compounds in general.

MK8 / Community awareness film
《雨来 风依旧》 is a community awareness short film telling a moving story of resilience and hope.
Proudly presented by Dietchain (MK8), directed by acclaimed filmmaker Jess Teong (张爵西), and starring 陈立扬, 刘铨盛 and 陈凯旋, the film is inspired by the true story of Tony, an entrepreneur living with kidney disease. Through her compassionate visual storytelling, Jess Teong sensitively portrays his courage and determination in the face of adversity.
The rain symbolises life's trials, while the wind represents the protagonist's free and unrestrained spirit. Through every change in fortune, he keeps an open heart and moves forward with courage.
When storms arrive, he never loses his longing for light. When a gentle breeze passes, he embraces every possibility. Meeting life's ups and downs with a smile, he spreads hope and joy like dandelion seeds on the wind. This is both a true story of overcoming adversity and a journey of inner transformation and renewal.
On life's journey, we need not fear the storms: the wind remains, and he is a light that never fades. Through this short film, we hope to inspire greater awareness of health, appreciation of life and the courage to live with hope.

MK8 is kidney care water containing 100% natural trace-element compounds, with no added chemical ingredients, alcohol or preservatives. MK8 is easily absorbed by the kidneys and provides kidney care. Through the use of quantum molecular band processing technology, the encapsulated trace elements are fully released into a free state that can be directly absorbed and used by cells.
MK8 contains more than 20 trace-element compounds to strengthen kidney function.
The six main trace-element compounds in MK8 are:
Zinc compounds - promote wound healing, maintain cell membranes and promote cell regeneration.
Manganese compounds - strengthen kidney function.
Selenium compounds - prevent cell damage.
Potassium compounds - promote the normal functioning of all cells, tissues and organs.
Calcium compounds - help transport nutrients and other substances through cell membranes.
Cobalt compounds - promote the metabolism of every cell in the body.
MK8 is mainly intended for four groups: kidney disease patients, seniors, office workers, and infants and adolescents.
Body aches and pain, increased perspiration, stronger steps, increased urine output, stronger urine odor, mental fatigue or increased energy.
Yes, dietary restrictions are recommended. In particular, people with poorer kidney function and dialysis patients need to avoid the following foods: all mushrooms, seafood, all alcoholic beverages, peanuts, caffeinated drinks, and all beans (for example: soybeans).
They often feel weak, have no appetite, react slowly, are forgetful, have unstable emotions, are stubborn, lose their temper easily, and often forget what they were going to say halfway through speaking.
Unlike the heart or stomach, the kidneys do not show pain when they are unwell. They quietly play the role of a “cleaner.” For this reason, the damage they suffer is also silent. By the time symptoms appear and a diagnosis is made, kidney function may already have been reduced by half. Therefore, the concept of kidney care needs to be taught from childhood, and it is recommended to begin using MK8 during adolescence. This is a stage of physical development, and a good kidney environment is healthier and more positive for an adolescent’s future physical and mental development.
