Fifty Years in New Hampshire
MegaFood was founded in 1973 in Manchester, New Hampshire, at a time when the supplement industry was dominated by isolated synthetic vitamins. The company's founding premise was that vitamins derived from or bonded to whole food sources would be more bioavailable and nutritionally complete than pure synthetic isolates — a position that has remained central to the brand for over fifty years.
The Manchester facility processes fresh produce delivered directly from farm partners. MegaFood purchases hundreds of thousands of pounds of fresh produce annually, sourced from farms in Vermont, Wisconsin, Hawaii, and California. The whole food processing happens at the New Hampshire facility, where ingredients are dried and prepared before being incorporated into supplement formulations.
Farm-to-Tablet Philosophy
MegaFood's manufacturing process begins with real food: produce is sourced from farm partners with established relationships and consistent growing practices. At the Manchester facility, fresh produce is dried using a proprietary process designed to preserve the nutritional content of the original food. The dried whole food material is then combined with vitamins and minerals to create the finished supplement.
The approach produces supplements that contain the cofactors, phytonutrients, and enzyme activity present in whole foods alongside the targeted vitamins and minerals. Whether these food matrix components meaningfully enhance absorption compared to isolated vitamins is debated in nutritional science, but MegaFood's commitment to the approach has been consistent through five decades of operation.
Non-GMO and Gluten-Free Standards
MegaFood products are Non-GMO Project Verified and certified gluten-free, standards that require third-party testing and supply chain documentation rather than self-certification. For consumers with celiac disease or gluten sensitivity, the certified gluten-free designation means the manufacturing facility and supply chain have been audited to confirm the absence of gluten contamination — not just that gluten is absent from the formula on paper.
The Non-GMO Project Verification requires annual supplier reviews and product testing, creating accountability beyond labeling claims. For buyers who prioritize both supplement quality and supply chain transparency, MegaFood's domestic manufacturing combined with third-party certifications represents a combination that is less common in the supplement category.
