Dual Pathway, Not Single Pathway. Most creatine on the market is just monohydrate. Monohydrate alone is built for muscle — it goes to the cells that power physical performance, fills your stores, and stops there. Creatine Reserve adds 750 mg of GAA, the molecule your body uses to make its own creatine. GAA crosses the blood-brain barrier through SLC6A8, the brain’s preferred transporter. The muscle version can’t use this pathway.* The Cognitive Part of Your Stack, Consolidated. Reserve replaces the separate creatine, GAA, B-complex, and taurine bottles most longevity stacks already include. One capsule. Active methylated B6, B9, and B12 — the cofactors your body actually uses to convert creatine and GAA into the phosphocreatine your brain runs on.* No Loading. No Bloat. No Powder. The 20–25 g loading phase is the reason creatine got its bloat reputation. Reserve skips it. 3,000 mg + 750 mg GAA daily reaches saturation in 3–4 weeks. Capsules — no scoops, no shakers, no flavors, no grit.*
