Evidence Lab
Evidence Lab is a public education layer for ingredient evidence, practical coaching context, safety considerations and supplement-combination review.
Claim-level summaries keep the ingredient evidence separate from product quality and client-specific decisions.
Safety notes, interactions and referral reminders sit beside the claimed benefit, not hidden at the bottom.
Combination pages can explain rationale, overlap, uncertainty and risk without implying a universal stack.
Published articles should be backed by traceable references and review history before they go public.
Published Supplements
Only reviewed and published records appear here.
Strong
Beta-alanine is a chronic-loading performance supplement that raises muscle carnosine and may support high-intensity work lasting roughly one to several minutes. It is not an acute pre-workout stimulant, and tingling is common but can often be reduced by divided doses.
Strong
Caffeine can acutely improve alertness, attention and several exercise-performance outcomes, especially endurance and high-intensity efforts. Benefits depend on dose, timing, tolerance, sleep impact and individual response.
Emerging / Mixed
Citrulline malate is a nitric-oxide-pathway supplement with mixed evidence for exercise performance. Acute studies sometimes show small improvements in repetitions or fatigue resistance, but formulation quality and malate ratio uncertainty make claims less settled than stronger Group A supplements.
Strong
Creatine monohydrate is a well-studied supplement that can improve repeated high-intensity exercise and support strength gains from resistance training. Benefits vary, endurance effects are limited, and product quality and individual health context still matter.
Emerging / Mixed
L-theanine is a tea-derived amino acid with emerging evidence for calm focus and selected cognition or stress-related outcomes. The strongest practical use is often in combination with caffeine rather than as a standalone sports-performance supplement.
Strong
Sodium bicarbonate is an extracellular buffering supplement with evidence for selected high-intensity exercise tasks, but gastrointestinal tolerance, sodium load and medical context determine whether it is practical.
Combinations
Combination pages are designed to separate ingredient rationale from safety overlap, uncertainty and product-quality questions.
Coach-only drafting and review tools can prepare records first. Public pages remain empty until records are explicitly published.
