Kinetics
USMLENutrition Prep
Ace clinical nutrition science. Master USMLE nutrition biochemistry through clinical reasoning — not recall. Built for the June 2026 USMLE nutrition content expansion.
Android post-launchThe Loop
Every session runs
the same loop.
Open a patient vignette
A clinical scenario appears. Review the history. Start building a mental model.
Order relevant labs
Select the tests that matter. Interpret the results in context.
Commit to a differential
Name the diagnosis. Own the decision before you see the mechanism.
Map the biochemistry
Drag substrates, enzymes, and cofactors into a mechanism chain that explains why the clinical picture emerged.
Spaced repetition takes over
Miss a pathway? It returns tomorrow. Nail it? The interval grows — 3 days, 7 days, 21 days. Durable knowledge.
Key Features
Biochemistry pathways, not passive flashcards.
62 Clinical Cases
Physician-reviewed vignettes covering deficiency, toxicity, and dysregulation. Every case ties back to a mechanism.
37 Interactive Pathways
Drag substrates, enzymes, and cofactors. Build the biochemistry chain that explains the clinical picture. Clinical pearls at every step.
Spaced Repetition
3-day, 7-day, 21-day intervals built directly into the study loop.
Drug-Nutrient Pack
Dedicated content on drug-nutrient interactions and clinical implications.
Lifespan Pathways
Age-specific pathways — pregnancy, pediatrics, geriatrics — with unique mechanisms.
Content
Clinical cases covering all 21 USMLE Step 1 nutrients
Every vitamin, every mineral, every major macronutrient pathway.
13 Vitamins
A, D, E, K, C, B1 (thiamine), B2 (riboflavin), B3 (niacin), B5, B6, B7, B9 (folate), B12 (cobalamin)
6 Minerals
Iron, calcium, magnesium, zinc, iodine, selenium
Carbohydrate Metabolism
Glycolysis, gluconeogenesis, glycogen metabolism, pentose phosphate
Fatty-Acid Metabolism
Beta-oxidation, ketogenesis, fatty-acid synthesis, lipid transport
Why Kinetics
Built for the 2026 USMLE
nutrition content update.
Nutrition biochemistry and chronic-disease clinical thinking are now core — not peripheral. Kinetics is built for the new bar: reasoning from patient to mechanism, with spaced repetition keeping it durable between now and test day.
Built for USMLE candidates
USMLE Step 1
Biochemistry foundations for the new nutrition content
USMLE Step 2 CK
Clinical nutrition reasoning in patient scenarios
USMLE Step 3
Advanced clinical decision-making with nutrition axes
