Leah Segedie
Founder of Mamavation — commissions independent lab tests of food and consumer products
Founder of Mamavation, Segedie commissions independent laboratory tests of foods and consumer products — rice for heavy metals, flours for glyphosate, olive oils for phthalates — and publishes the results brand by brand. She is also the founder of ShiftCon, a mom-blogger network, and a long-standing figure in the 'MAHA mom' demographic.
Coverage status — October 2026: Segedie holds no formal administration role. She is tracked as the strongest lab-methodology documenter in this section: the tests she commissions are the underlying evidence many other food voices cite.
Her documented testing covers rice for arsenic, lead, cadmium, and mercury; organic flours for glyphosate; olive oils for phthalates; strawberries for 500+ pesticides; vitamin D supplements for PFAS, phthalates, and heavy metals; and PFAS in activewear and period underwear. Her stated audience was ~200,000 Facebook fans (her own statement, ~2022); a current total is not verified.
Her evidence style is what sets her apart: products are bought at retail, kept in their packaging, and sent to EPA-certified / ISO-accredited third-party labs (e.g., Galbraith Labs), with results published brand by brand including ppm values. She works with scientific advisors, including Pete Myers of Environmental Health Sciences, and publicly notes the limits of her testing — a caveat this site preserves alongside her results.
Why tracked here: she owns the commissioned-lab-testing beat — retail products, accredited labs, published numbers — for the food and consumer-products contamination story.
