**Chelated minerals** are mineral ions bound to organic ligands — usually amino acids — to improve absorption and reduce gastric irritation relative to plain inorganic salts. The Institute's material names the **TRAACS** (Albion) chelate technology specifically.

The organising principle of the whole Part II material is here in one line: **form governs uptake**. Which nutrient matters less than which form of it.

## Why chelation helps

A mineral salt dissociates in the stomach and the free ion must then compete for a divalent-metal transporter, is vulnerable to phytate and oxalate binding, and irritates gut mucosa. A **bis-glycinate** chelate — two glycine molecules wrapped around the ion — is small, neutral, stable at gut pH and can be absorbed as an intact molecule via peptide/amino-acid routes, sidestepping both the competition and the irritation.

## Practical comparisons

- **Iron**: ferrous **bis-glycinate** vs ferrous sulfate — comparable absorption at lower elemental dose, with markedly less constipation and nausea. This is the clearest real-world win for chelation, and iron is the mineral people most often abandon over side effects.
- **Magnesium**: **glycinate** (well absorbed, calming, minimal laxative effect) and **citrate** (well absorbed, laxative at dose) versus **oxide** — which is roughly 4% absorbed and is mostly a laxative sold as a supplement. Magnesium **threonate** is marketed for CNS penetration on thin evidence.
- **Zinc**: picolinate, bis-glycinate and citrate all outperform oxide.
- **Calcium**: **citrate** does not require stomach acid; **carbonate** does, and therefore fails in people on proton-pump inhibitors — a common and avoidable interaction.

## Elemental content is the catch

A chelate is mostly ligand by weight. **1,000 mg of magnesium glycinate is roughly 140 mg of magnesium.** Labels vary in whether they state the compound or the element, and comparisons between products are frequently made between the wrong numbers. Read the elemental figure.

## Liposomal delivery

The same logic applied differently: ascorbate or a mineral packaged in phospholipid vesicles to raise the absorbed fraction. See Liposomal Vitamin C.

## Cautions

- **Iron** — overdose is a leading cause of poisoning death in small children, and haemochromatosis makes supplementation dangerous. Do not supplement iron without a ferritin measurement.
- **Zinc** displaces **copper**; chronic zinc without copper causes copper-deficiency anaemia and myelopathy.
- **Magnesium** accumulates in renal impairment.
- **Calcium** binds and blocks the absorption of iron, zinc, levothyroxine and the tetracycline and quinolone antibiotics — separate the doses.
- Better absorption means it is easier to reach a toxic intake, not harder.
