Sarah Caldwell, M.S.

Sarah Caldwell holds a Master of Science in Nutritional Science from Penn State University and has spent 12 years covering the intersection of evidence-based nutrition, supplement research, and consumer health journalism.

At Nova Health Lab, Sarah leads the editorial review process — evaluating supplement ingredient quality, reviewing clinical study data, and ensuring that every product analysis is grounded in publicly available science rather than manufacturer marketing claims.

Her approach is straightforward: if a clinical study is cited, she verifies it. If a supplement ingredient has limited human data, she says so. She does not evaluate products she hasn't researched thoroughly, and she holds the Nova Health Lab review methodology to the same standards she applied during her graduate work.

Before joining Nova Health Lab, Sarah contributed to several consumer health publications and worked as a research assistant in a university clinical nutrition laboratory, where she developed an eye for how mechanistic study data is often overstated in popular health media.
