Mineral metabolites in organic acid testing reveal functional mineral status by reflecting enzyme activity and metabolic health related to essential minerals like magnesium, manganese, calcium, and iron.
Common Mineral-Related Organic Acid Markers and What They Reflect:
| Marker | Mineral Association | Significance |
|---|---|---|
| Pyroglutamic acid | Magnesium | Elevated levels can indicate magnesium deficiency or glutathione depletion (which involves Mg-dependent enzymes) |
| 2-Hydroxyisovaleric acid | Magnesium | Increased with magnesium deficiency affecting BCAA metabolism |
| Citric acid | Magnesium, Calcium | Low levels may reflect magnesium or calcium imbalance impacting the Krebs cycle |
| Fumaric acid | Manganese | Changes can reflect manganese-dependent enzyme activity |
| Malic acid | Magnesium, Manganese | Alterations can indicate deficiencies affecting energy production |
| Succinic acid | Iron | Reflects iron-dependent enzyme activity in the Krebs cycle |
| Ethylmalonic acid | Sulfur | Linked to sulfur metabolism and cofactors |
🔍 How Mineral Metabolites Help:
-
Assess mineral sufficiency or deficiency indirectly via metabolic intermediates
-
Detect enzyme cofactor imbalances, since many enzymes require minerals to function
-
Identify mitochondrial and energy metabolism disturbances caused by mineral deficits
-
Guide targeted nutritional supplementation to support metabolism and detoxification
Phosphoric acid is a normal component of urine and is sometimes included in urine organic acid profiles to reflect phosphate metabolism, acid-base balance, and renal function.
🔬 What Is Phosphoric Acid?
-
A weak acid derived from phosphorus, a vital mineral in the body.
-
In urine, it reflects the body’s excretion of phosphate, which plays a role in:
-
Energy metabolism (as part of ATP)
-
Bone health (combined with calcium)
-
Buffering systems (maintaining pH balance)
-
🧪 In an Organic Acid Test:
Phosphoric acid is not always a core diagnostic marker, but when reported:
| Level | Possible Interpretation |
|---|---|
| High | – High protein intake – Acidosis – Kidney issues – Phosphate over-supplementation |
| Low | – Low dietary phosphate – Magnesium or vitamin D deficiency – Poor renal excretion |
Phosphoric acid is a marker of vitamin D and calcium. This marker indicates whether vitamin D receptors are activated. If phosphoric acid is low, then the person is likely vitamin D and/or calcium deficient. Low levels can be due to low phosphate consumption, low digestive juice production, or deficiencies in vitamin D, vitamin K2, or magnesium. It is recommended to do a Vitamin D test if the phosphoric acid is low.
Low levels of phosphoric acid point to a deficiency, which might stem from:
- Poor phosphate intake
- Impaired production of digestive juices
- Deficiency of vitamin K2
- Deficiency of magnesium
High levels of phosphoric acid might mean that a person has been exposed to toxic levels of lead, or that they’re getting too many phosphates in their diet (often from high consumption of processed foods). It can also result from inappropriate vitamin D supplementation.
Low magnesium or calcium markers on the OAT might suggest a need to assess Vitamin D, because:
-
Vitamin D helps regulate calcium and phosphorus absorption.
-
Magnesium is required to activate Vitamin D in the liver and kidneys.
In the first blood test (2016) it was indicated as low, this test did not indicate any Phosphoric acid. The low reading was why we started using the probiotic with Vit D3.
Vitamin D 29.1 (result) L / 30 – 70 (range)
Unfortunately, the South African test did not test for phosphoric acid.
