My body cannot absorb some vitamins from food due to PPIs usage, hoped this could help, however after 2 weeks usage there is no effect at all. A few AIs doubts the multivitamins could be delivered transdermally efficiently, though it depends on each individual. Still I have no option and will try them for 6 months. "Transdermal vitamin patches, like the PatchAid Multivitamin Patch, are designed to deliver nutrients directly through the skin into the bloodstream, bypassing the digestive system. This method can be beneficial for individuals who have difficulty absorbing nutrients orally due to digestive issues. However, the effectiveness of transdermal absorption for vitamins is still debated. While some users report positive experiences, scientific research on the efficiency of vitamin patches compared to traditional oral supplements is limited. If you're considering using them, it might be helpful to consult a healthcare professional to ensure you're getting the nutrients you need." "Vitamin patches have some potential drawbacks that are worth considering: - Limited Scientific Evidence: Research on the effectiveness of transdermal vitamin absorption is still scarce, and many experts question whether vitamins can be absorbed efficiently through the skin. - Skin Absorption Challenges: The skin acts as a natural barrier, making it difficult for large vitamin molecules—especially water-soluble ones like B12 and C—to penetrate. - Variable Absorption Rates: Factors like skin type, hydration, and patch placement can affect how well nutrients are absorbed, leading to inconsistent results. - Regulatory Concerns: In some regions, vitamin patches are not regulated as dietary supplements, meaning their safety and efficacy may not be thoroughly evaluated. - Potential Cost: Vitamin patches can be more expensive than traditional oral supplements, and their effectiveness may not justify the higher price." "Transdermal absorption allows vitamins to pass through the skin and into the bloodstream, bypassing the digestive system. This method is used in vitamin patches, which release nutrients gradually over time. The skin has multiple layers, with the epidermis acting as the primary barrier. For vitamins to be absorbed, they must penetrate this layer and reach the dermis, where blood vessels can transport them throughout the body. Factors like skin hydration, thickness, and location affect absorption rates—thinner, well-hydrated skin tends to absorb nutrients more effectively. However, the effectiveness of transdermal vitamin absorption is still debated. While some nutrients, like nicotine and certain medications, are successfully delivered through the skin, vitamins have larger molecular structures, making absorption more challenging. Some studies suggest that fat-soluble vitamins (like D and A) may be more suited for transdermal delivery than water-soluble ones (like B12 and C)."
