FULVIC ACID PURITY AND DOSE: THE 90% STANDARD

The Purity Problem

Fulvic acid as a raw ingredient varies more in purity than most supplement consumers know. Commercial fulvic acid is typically extracted from leonardite, peat, or other humic-substance sources, and the extraction process determines what fraction of the final powder is actual fulvic acid versus accompanying humic acid, humin, mineral residue, or extraction solvent residue. Suppliers commonly sell preparations at anywhere from 20 percent to 95 percent fulvic acid content depending on the extraction route.

A "150mg fulvic acid" label on a supplement bottle does not tell you what you are actually getting. 150mg of 90 percent fulvic acid is not teh same product as 150mg of 30 percent fulvic acid even if the labels look identical. The functional dose differs by 3x. (I went through three different fulvic acid suppliers before landing on the one we use, and the certificate-of-analysis differences between them were embarrassing for the cheaper end of the market.)

Why We Use 90 Percent

The H180 formula uses fulvic acid at 90 percent purity, which is near the high end of what commercial extraction processes can reliably produce at industrial scale. The choice is driven by two things: predictability of the chelation capacity per milligram (so the dose math against DHM stays clean serving-to-serving), and minimization of co-extracted humic acid and mineral residue that don't add anything to the function.

The 150mg dose is sized to match the chelation capacity of fulvic acid at this purity level against the DHM input dose in the same serving. This is what makes the membrane-transport assist actually predictable rather than a wild card.

Safety at the Dose

A 2020 toxicological assessment of fulvic acid in animal models reported no significant adverse effects across a wide dose range, with no observed-adverse-effect levels well above any practical supplement dose¹. A separate toxicological evaluation of a combined fulvic-and-humic-acid preparation reached similar conclusions³. Mineral-profile characterization of fulvic-acid beverages found that trace metals delivered fall within ranges consistent with normal dietary intake even at higher servings². The safety margin is wide in the published toxicological data at least, but purity is still where the cheap suppliers cut corners, particularly around heavy-metal residue from the leonardite source.

What This Page Is Not Claiming

We are not claiming the 90 percent purity standard is uniquely "ours" or that lower-purity fulvic acid is unsafe at the doses typically used. The point is narrower: a delivery-agent function depends on knowing exactly how much chelation capacity you are putting in each serving, and you can't know that if the ingredient purity varies. Higher purity is the way to keep the chelation math honest⁴.
