Professional Summary

Supplement leadership backed by hands-on product work

Jake works at the intersection of supplement formulation, evidence review, and practical health education. As founder of USA Medical, he is responsible for translating research, labeling requirements, and real product-development decisions into clear guidance consumers can use.

His work is intentionally consumer-facing: explain what the evidence can support, identify what remains uncertain, and give readers enough context to make a more informed decision without presenting education as diagnosis or treatment.
