Humic acid is a mix of organic compounds that forms when plants decay in soil and peat. Supplement makers sell it in capsules or liquids, often bundling it with fulvic acid. The human body does not need it to function.
Marketers claim it helps move minerals around or supports digestion, but solid proof is absent. Most support comes from early lab work or animal tests. Human studies are rare and don't back these selling points.
No safe or effective dose exists for this ingredient. Products lack standardization, so one batch may differ wildly from the next. Some carry unwanted minerals or heavy metals unless properly purified. Pregnant or breastfeeding women should steer clear because safety is unknown. Pick products only from makers who verify purity.
