RESEARCH TOOLS

Free interactive tools, backed by research

Calculators and assessments built around the consumer health and product research published on GiftedPicks. Every tool is grounded in primary-source citations and links back to the underlying research.

In development

Tools we're actively building. If any of these would be useful to you and you want first access when they ship, drop us a note — user input shapes what we prioritize.

Supplement Stack Conflict Checker

Coming soon

Check whether the supplements in your stack have known interactions, absorption conflicts, or timing issues. Built from peer-reviewed pharmacology data.

Red Light Therapy Wattage Calculator

Coming soon

Input your treatment goal (hair regrowth, skin, recovery) and get the recommended irradiance, wavelength, and session-length range from the published trial literature.

Skincare Ingredient Conflict Checker

Coming soon

Paste your routine; get a per-step warning for known irritation pairs (retinoid + AHA, vitamin C + niacinamide, etc.) with the supporting research.

How these tools are built

Every tool starts with a peer-reviewed evidence base — we read the primary literature first, then design the inputs and weighting around what the published data actually supports. Tools are explicitly relative-ranking instruments, not precise medical instruments. Methodology is disclosed on each tool page.

Built by Kevin Geary. If you're a researcher with relevant expertise and want to suggest methodology improvements, please email kevin@giftedpicks.com.
