Ligands are ions, molecules or a molecular group that bind to another chemical entity to form a larger complex. In this episode we're exploring the world of mineral ligands, the combinations of mineral complexes commonly found in nutritional supplementation and the many myths and misnomers perpetuated largely by marketing and hype. But what are the facts? What is the clinical opportunity or drawback to using say Calcium Sulphate vs. Citrate, or Magnesium Oxide vs. Magnesium Aspartate?. What is the evidence for amino-acid chelates and how they work in the body? How can you choose the right combination to yield the highest bioavailability or the best clinical outcome? Today we welcome back Dr Bob Buist arguably one of Australia's foremost leading experts in the field of nutritional biochemistry to dispel some myths and deliver some clinical pearls of wisdom about selecting the right combinations.
