Ferrous Fumarate is synthetically produced, meaning it is manufactured through chemical processes rather than directly extracted from natural sources. Synthetic ingredients are extremely common in supplements and are not inherently less safe than natural alternatives. In many cases, synthetic production allows for higher purity and more consistent quality. The FDA regulates both natural and synthetic supplement ingredients under the same safety standards. GoodSupp rates ingredients based on their actual safety data regardless of whether they're natural or synthetic.
