Dietary minerals are consumed by millions of people each day but many lack the knowledge of how they are made. There are two major forms of minerals, one is natural and the other one is synthetic. Learning how to tell the difference between natural and synthetic minerals will help you choose a dietary supplement that is worth your money. In general, minerals that contained amino acid chelated minerals are good sources of minerals.

How to tell which forms of mineral is better

  • Calcium: Good source is from calcium amino acid chelate. Bad sources are from coral calcium, calcium hydroxyapatite, bitartrate, calcium gluconate and calcium carbonate. Coral calcium is not a good source of calcium because it usually has the highest in lead content.
  • Copper: Good source is from copper amino acid chelate and bad source is from copper gluconate.
  • Iodine: Good source are from kelp and iodine solution that is in the nascent iodine state. Bad source is from potassium iodine.
  • Iron: Good source is from iron amino acid chelate. Bad sources are from ferris sulfate, iron fumarate and iron gluconate.
  • Magnesium: Good sources are magnesium taurate and magnesium citrate because they are easy to absorb and utilize by the body. Magnesium from whole food is a good source too. Bad sources of magnesium are magnesium gluconate and magnesium oxide.
  • Potassium: Good sources are potassium citrate and whole food. Bad sources are potassium chloride and potassium gluconate.

The most common types of minerals used in dietary supplements are forms of mineral salts. These minerals have suffix such as sulfate, chloride or carbonate (i.e. chromium chloride). Mineral salts usually cause gastrointernal distress and are poorly absorbed. Dietary supplements with mineral oxides are also not good sources of minerals because mineral oxides are even less well absorbed by the body. Mineral oxides are usually listed with the suffix “oxide” at the end. The best forms of minerals are chelated minerals because these minerals are attached to amino acids and other synergistic components. By not extracting their synergistic components, minerals are more absorbable and easier to use by the body. Chelated minerals have suffix such as chelavite, chelazome or chelate at the end.

    hi, thanks soo for your info on natural vs. synthetic vitamins…my big dilemma…what brands to buy or which companies make healthy vitamins/supplements?? no one seems to want to tackle this concern…if i’m having the problem, i’m sure so many others are too. q. what about supplements like, coQ-10, selenium, l-arginine, etc.etc…do you have info on good/bad ingredients in these? thanks. liz
