Endurance athletes place significantly higher demands on their metabolic and cardiovascular systems — both of which depend on B12. It's required for red blood cell production (and therefore oxygen delivery), mitochondrial energy metabolism, and nerve signal efficiency. Athletes following plant-based diets face additional risk since B12 is found almost exclusively in animal products. Even subtle deficiencies can show up as unexplained fatigue, reduced endurance, or slower recovery.

Standard B12 tablets and capsules have to survive digestion before they can be absorbed — and absorption rates can vary significantly based on your gut health, age, and whether your body produces sufficient intrinsic factor (a protein needed to absorb B12 from the gut). Rho's liposomal liquid wraps methylcobalamin in phosphatidylcholine carriers that support direct cellular uptake, making absorption more efficient and reliable regardless of those variables.

Some athletes report feeling improvements in energy and mental clarity within a week. For others it takes two to four weeks of consistent daily use. B12 is a foundational nutrient — the benefits build over time and are best maintained through daily supplementation since the body doesn't store large amounts of water-soluble vitamins.

Yes — and it stacks particularly well with Rho Liposomal NAD+ for comprehensive cellular energy support. All Rho products are designed to work synergistically and can be combined into the same beverage for convenience.
