What is the purpose and source of each ingredient in Optimal Creatine PowderUpdated 2 hours ago
| Ingredient | Purpose |
| Magnesium | Magnesium is an essential cofactor for creatine kinase, the enzyme that converts creatine to phosphocreatine inside cells. Without adequate magnesium, this conversion is rate-limited regardless of how much creatine is present. Malic acid (malate) also participates in the Krebs cycle, supporting mitochondrial energy production.† |
| Sodium | Sodium is the co-transporter ion for SLC6A8, the primary creatine transporter responsible for moving creatine into muscle and brain cells. SLC6A8 is sodium-dependent: transporter activity is reduced when extracellular sodium is insufficient. The 75 mg dose addresses this transporter requirement without contributing a clinically significant sodium load.† |
| Creatine | Replenishes the phosphocreatine pool in muscle and brain tissue, supporting rapid ATP regeneration during high-intensity physical effort and cognitively demanding tasks. The 5g dose aligns with the maintenance dose used across the majority of efficacy trials.† † |
