ByHeart is a US infant-nutrition company founded in 2016 that makes Whole Nutrition Infant Formula, marketed on the promise of better science, better ingredients, and better quality. It sells direct-to-consumer through a Shopify storefront at byheart.com as well as through retail. The company ran its own clinical program and built its own manufacturing. In November 2025 ByHeart recalled all batches after Clostridium botulinum contamination linked to infant-botulism cases and paused production pending FDA clearance to resume. ByHeart is a portfolio company of D1 Capital. It publishes no first-party developer API; its only machine-discoverable surface is the Shopify Customer Account API (OpenID Connect / OAuth 2.0) advertised under its domain.
