Not enough information is known at this time to suggest an optimal dose of L-Threonate in isolation.

Mineral chelations of L-Threonate should be dosed according to the active mineral content of the chelation.

Edit1. Structure and Sources

L-Threonate is a deriviative of L-ascorbic acid 2-phosphate (which in and of itself is a derivative of Ascorbic Acid, otherwise known as Vitamin C).

Edit2. Effects on Hair Loss

L-threonate is able to repress the expression of a gene known as dickkopf-1 (DKK-1) which is upregualted by Dihydrotestosterone (DHT) in male pattern baldness when co-cultured.^[1] It seems to work similarily to L-ascorbic acid 2-phosphate via alkaline phosphatase activity and releasing ascorbic acid into the cell.^[2][3]

Edit3. Effects on Bone Metabolism

Independent of its use as a conjugate to Calcium as Calcium-L-Threonate (to be discussed), L-Threonate has been investigated for its usage in bone health. It has been implicated as working synergistically with calcium in the production of collagen and mineralized nodules.^[4][5] and augments the uptake of ascorbic acid into fibroblasts.^[6] By itself, L-theonate can also act on osteoclasts in an anti-osteoporotic manner.^[7]

Edit4. Use as a mineral chelation

Minerals bound to L-theonate tend to have rapid intestinal uptake and report minimal gastrointestinal side effects. Minerals such as Iron^[8][9], Calcium^[5], and Magnesium^[10][11] have been tested with L-Threonate chelations.^[12]

Edit5. Safety and Toxicity

The safety and toxicity of L-threonate has not been investigated.
