Transdermal diffusion allows B12 to cross the skin barrier directly into the bloodstream, bypassing digestive transit and the losses linked to intestinal absorption (particularly problematic for B12). Studies show that the transdermal B12 patch offers bioavailability equivalent or superior to oral supplements, particularly in people with deficient intrinsic factor.
Yes. Vitamin B12 is essential for cellular energy production (Krebs cycle), DNA synthesis and maintenance of the neurological myelin sheath. A deficiency causes chronic fatigue, brain fog and muscle weakness. The Barrière B12 patch provides a continuous and stable supply over 24 hours, without peaks or drops.
Vegans and vegetarians (B12 is almost exclusively of animal origin), people over 50 (reduced digestive absorption), people taking metformin (diabetes) or PPIs (antacids), and people with Crohn's disease or coeliac disease. The patch is the ideal solution when digestive absorption is compromised.
Apply the patch to a clean, dry, hair-free area of skin (inner wrist, shoulder, upper back). The patch must stay in place for 24 hours. Vary application sites to avoid irritation. Do not apply to irritated or damaged skin. Store patches away from heat and humidity.
Yes. The Barrière patch contains no animal products. It is the preferred solution for vegans who do not consume animal-origin B12 and prefer to avoid the animal gelatin found in many capsules. The methylcobalamin used is the most bioactive and assimilable form of B12.
Generally very well tolerated. Rare local redness at the application site (a normal reaction to the adhesive, which disappears after removal). If you have very sensitive skin or contact dermatitis, test on a small area first. Not recommended in case of allergy to acrylic adhesives. No known toxicity from excess B12 (water-soluble).
