Energy fuels every function in the human body—from blinking to thinking to repairing cells. Yet many people today struggle with fatigue, poor sleep, or stress. Robuvit®, a natural extract from French oak wood, offers a safe, caffeine-free solution supported by more than 30 clinical studies, including research in fatigue, stress, recovery and sleep.
Clinical results
Robuvit® supplementation has consistently shown measurable benefits across different populations:
-
In healthy adults aged 45–65, four weeks of use significantly increased energy and reduced fatigue.
-
In men with reduced vigor, Robuvit® improved physical and mental vitality, reducing apathy and weakness.
-
Among 108 professionals, four weeks of supplementation improved coping, mood and energy levels.
-
In colon cancer patients post-chemotherapy, Robuvit® reduced fatigue by 70% and improved fitness, mood and work ability after six weeks.
-
In people with chronic fatigue symptoms, Robuvit® increased energy by 48% after four weeks and improved sleep and mood-related symptoms after three months.
Across multiple studies, Robuvit® also showed significant improvements in sleep quality, with participants sleeping 33% more and reporting better mood and energy in the morning.
How it works
Robuvit® works at the cellular level by supporting mitochondria—the body’s powerhouses. Once ingested, Robuvit® is metabolized into urolithins, notably urolithin A, which promotes mitophagy: the removal of damaged mitochondria and the generation of new ones. This process optimizes energy production in the form of ATP. Robuvit® also stimulates ribosome biogenesis, enhancing protein synthesis needed for enzymes, hormones and muscle fibres.
Additionally, Robuvit® provides antioxidant support. Clinical studies have shown reduced oxidative stress markers and increased antioxidant enzyme activity, helping protect mitochondria and sustain energy output.
Applications
The benefits of Robuvit® extend to multiple areas of wellness:
-
Daily energy and fatigue relief – safe, stimulant-free support to combat everyday tiredness.
-
Sleep and mood – improved sleep duration and mood balance, helping people feel refreshed.
-
Recovery and performance – faster recovery after illness, surgery, or intense physical activity.
