Dr Stanfield

Dr Stanfield sells physician-formulated dietary supplements that focus on gut health, immune support and healthy aging. Single bottles run $35-$55 and 3-pack bundles drop the per-unit cost to the low-$30s, placing the line in the mid-range tier. All inventory is sold direct-to-consumer through drstanfield.com; no retail or third-party e-commerce listings are used. The brand’s point of difference is that every capsule, powder or soft-gel is designed by Dr. James Stanfield, a board-certified M.D. who publishes ingredient rationale and third-party lab certificates on each product page. Flagship SKUs include “Gut Restore” (a spore-based probiotic plus post-biotic blend) and “NMN + Resveratrol,” a two-capsule longevity combo that has driven most of the site’s five-star reviews. Core buyers are health-conscious adults aged 35-60 with discretionary income who research PubMed links before purchasing and value transparency over celebrity endorsements. They typically follow intermittent-fasting or bio-hacking routines and want small-batch, USA-made formulas from a single clinician rather than a conglomerate catalog. Competitors range from low-cost Amazon probiotics to premium longevity brands sold through subscription wellness platforms. Dr Stanfield differentiates by limiting the catalog to six SKUs, offering one-time purchases with no auto-ship default, and backing every batch with publicly viewable COAs linked to the exact lot number on the bottle.
