Zeolite Sum

ZED Health offers a combination of zeolite clay and humic acid. Zeo Natural sells a combination of zeolite and humic &fulvic acid. The scanning electronmicrographs of analcime, Phillipsite, Faujasite, Erionite, and Clinoptilolite. in this post’s image are from PubChem and Internet image searches. The above list of zeolite minerals with embedded links reference images uploaded on ResearchGate. They link to the publication. This post was going to be about whether is is safe to combine zeolite with humic and fulvic acids. The question becomes which zeolite? We need our suppliers to tell us this before we even consider cobining them with other stuff.

Using a review as a spring board

The Mastinu review makes it clear fast that the zeolites are a family of minerals containing SiO4 and AlO4 subunits connected by shared oxygen atoms. [1]

Adapted from Table 1 ref [1]. The Maccarinelli publication gives a much better review of the literature.

The approach taken on this post will be to briefly discuss the reference in the abbreviated Table 1 and meld in publications of that zeolite isoform with humic and/or fulvic acid.

  • Fulvic acid is straw-colored extract of humus that remains after humic acid has been precipitated with acid.
  • Humic acids are degradation products of organic material that are soluble in alkaline solutions.
  • Lignins are complex polyphenolic polymers that form the basis of plant cell walls.

Chabazite, Phillipsite, and Analcime

The clay came from a region near Bolsena lake in Central Italy.

  • 33.7% chabazite [CaAl2SiO12×6(H2O)]
  • 17.0% phillipsite [(K,Na,Ca)1-2(Si,Al)8O16×6(H2O)]
  • 6.1% analcime [NaAlSi2O6×H2O].
  • 18% sanidine K(AlSi3O8)
  • 14.6% plagioclase NaAlSi3O8 to CaAl2Si2O8
  • 10.6 % muscovite mica,KAl2(AlSi3O10)(F,OH)2, or (KF)2(Al2O3)3(SiO2)6(H2O
  • No traces clinoptilotite were found

Note that this clay is far from pure. The authors did not mention how they came to this determination. [2]


  • 25 clinically healthy male (40 ± 3 years, 13 smokers, 12 non smokers
  • Subjects were following a typical mediterranean diet and leading a non-sedentary life style.
  • received for 4 weeks, twice a day, 1/2 h before breakfast and dinner, 3 g of chabazite/phillipsite/analcime as powder suspension dissolved in water.
*p<0.05 vs T0; **p<0.001 vs T0. GLUT PER: gluthatione peroxidase; GLUT RED: gluthatione reductase; SOD: superoxide dismutase; TAS: total antioxidant status; TBARS: thiobarbituric acid reactive substance. [2] T0 is before and T1 after treatment.
  • Glutathione peroxidase is an enzyme that catalyzes this reaction 2GSH + H2O2 → GS–SG + 2H2O The reference value is 4171–10881 U/L of whole blood.
  • Glutathione reductase is an enzyme that catatalyzes this reaction GSSG + H+ + NADPH → 2GSH + NADP+ The reference value is 33–77 U/l of plasma.
  • SOD superoxide dismutase converts superoxide to hydrogen peroxide and water. The reference value is 164–240 U/ml of whole blood.
  • Total antioxidant status reference range is 1.3–1.7 mmol/l of plasma.
  • TBARS lipid peroxidation products have a reference value of

No PubMed documents were found for analcime and humic or fulvic acid. Zang and coauthors (2022) studied the ability of analcime to degrade lignins to constituent monophenols. [7] The synergetic effect of the micro-mesoporous structure and enhanced acidic sites of analchime were key to regulating the monomer composition and the yield of monophenols. [7] Could humic and or fulvic acid be degraded by analcime?

Clays in detail

Information in these posts started out, but then got moved.

Phillipisite supplementation of dogs on an almost human diet has been shown to result in probably favorable changes in the microbiome.

Clinoptilolite has been tested as an enhancer of intestinal barrier function in endurance athletes.
