Science-First Supplement Formulation
InYoung was founded on a simple premise: supplements should be held to the same standard as medicine. That means evidence first, always—and no exceptions for trendy or profitable ingredients that lack rigorous support.
Formulation Principles
Physician-Designed Formulas
Every product is developed in collaboration with board-certified physicians who specialize in integrative medicine and longevity. Clinical expertise informs every decision.
Evidence-Informed Ingredients
We only include ingredients backed by peer-reviewed clinical evidence. No proprietary blends—full transparency on every label. If we can't point to the study, we don't use the ingredient.
Clinically Meaningful Doses
Our doses match or exceed the amounts used in published clinical trials. Sub-therapeutic doses are not science—they're marketing. Every milligram is intentional.
No Trends or Hype
We don't chase viral ingredients or make claims we can't support. If the science isn't there, neither are we. Period.
Research Focus Areas
Our medical and scientific teams continuously review the literature across these core domains to ensure our formulas stay current with the best available evidence.
Cellular Longevity
We study the mechanisms of cellular aging—telomere maintenance, mitochondrial function, and senescence pathways—to identify ingredients that support healthy lifespan.
Dermatological Health
Our skin health formulas are built on dermatology literature exploring collagen synthesis, oxidative stress, UV protection, and barrier function from the inside out.
Hormonal Balance
We review endocrinology research on the hormonal shifts of your 30s and 40s—and identify evidence-based nutritional strategies to support energy, mood, and metabolic health.
Personalized Nutrition
No two bodies are the same. We draw from nutrigenomics and personalized medicine research to ensure our recommendations adapt to your individual profile.
Science FAQs
How do you select ingredients?
Every ingredient must clear a three-step review: (1) peer-reviewed evidence of efficacy, (2) a safety profile reviewed by our medical advisory board, and (3) a clinically meaningful dose that matches or exceeds trial dosages. Ingredients that fail any step are excluded.
Are your products tested for purity and potency?
Yes. All InYoung products are manufactured in cGMP-certified facilities and undergo third-party testing for identity, potency, and absence of heavy metals, microbials, and pesticides. Certificates of Analysis are available on request.
Do your formulas interact with medications?
Some supplements can interact with medications. We recommend consulting your physician or pharmacist before starting any new supplement, particularly if you are on prescription drugs. Our assessment asks about medications to help surface potential concerns.
Why do you use a personalized assessment instead of one-size-fits-all bundles?
The scientific literature increasingly supports individualized approaches to supplementation based on age, sex, lifestyle, health goals, and existing deficiencies. Our assessment maps your profile to formulas where the evidence of benefit is strongest for someone like you.
