体育投注网址Minerals are key nutrients that your body requires to function. They affect various aspects of bodily function, such as growth, bone health, muscle contractions, fluid balance, and many other processes.

However, many are difficult for your body to absorb. That’s why chelated minerals, which are supplements touted for improved absorption, have gained interest recently.

Chelated minerals are bound to compounds like amino or organic acids, which are meant to boost your body’s uptake of the mineral at hand.

This article explains whether chelated minerals are effective.

).

Chelated minerals are meant to boost absorption. They’re bound to a chelating agent, which are typically organic compounds or amino acids that help prevent the minerals from interacting with other compounds.

For example, chromium picolinate is a type of chromium attached to three molecules of picolinic acid. It’s absorbed through a different pathway than dietary chromium and appears to be more stable in your body (, ).

Summary

Chelated minerals are minerals bound to a chelating agent, which is designed to enhance their absorption in your body.

体育投注网址Most minerals are available in chelated form. Some of the most common include:

They’re typically made using an amino or organic acid.

Amino acids

These amino acids are commonly used to make mineral chelates:

  • Aspartic acid: used to make zinc aspartate, magnesium aspartate, and more
  • Methionine: used to make copper methionine, zinc methionine, and more
  • Monomethionine: used to make zinc monomethionine
  • Lysine: used to make calcium lysinate
  • Glycine: used to make magnesium glycinate

Organic acids

Organic acids used to make mineral chelates include:

  • Acetic acid: used to make zinc acetate, calcium acetate, and more
  • Citric acid: used to make chromium citrate, magnesium citrate, and more
  • Orotic acid: used to make magnesium orotate, lithium orotate, and more
  • Gluconic acid: used to make iron gluconate, zinc gluconate, and more
  • Fumaric acid: used to make iron (ferrous) fumarate
  • Picolinic acid: used to make chromium picolinate, manganese picolinate, and more
Summary

体育投注网址Chelated minerals are usually joined to either organic acids or amino acids. Most mineral supplements are available in chelated form.

).

Similarly, a study in 30 adults noted that magnesium glycerophosphate (chelated) raised blood magnesium levels significantly more than magnesium oxide (non-chelated) ().

What’s more, some research suggests that taking chelated minerals may reduce the total amount you need to consume to reach healthy blood levels. This is important for people at risk of excess mineral intake, such as iron overload.

For example, in a study in 300 infants, giving 0.34 mg per pound of body weight (0.75 mg per kg) of iron bisglycinate (chelated) daily raised blood iron levels to levels similar to those caused by 4 times that amount of iron sulfate (non-chelated) ().

Yet, not all studies give the same results.

A study in 23 postmenopausal women showed that 1,000 mg of calcium carbonate (non-chelated) was more rapidly absorbed and raised blood calcium levels more effectively than the same amount of calcium citrate (chelated) ().

Meanwhile, a study in pregnant women with iron deficiency found no significant difference in blood iron levels when comparing chelated iron (ferrous bisglycinate) with regular iron (ferrous sulfate) ().

In general, animal studies indicate that chelated minerals are absorbed more effectively (, ).

体育投注网址However, these findings should be interpreted with caution, as animals have significantly different digestive tracts than humans. These differences can affect mineral absorption.

体育投注网址Given that the current research is mixed, more research on chelated minerals is needed.

Summary

Current research provides mixed results on whether chelated minerals are absorbed better than regular minerals. More studies are needed before one can be recommended over the other.

Because chelated minerals are bound to an amino or organic acid, they don’t require as much stomach acid to be efficiently digested ().

Similarly, people who experience stomach pain after taking supplements may benefit from chelated minerals, as they’re less dependent on stomach acid for digestion.

体育投注网址Nonetheless, regular, non-chelated minerals are sufficient for most adults.

体育投注网址Plus, chelated minerals tend to cost more than non-chelated ones. If cost is a concern for you, stick with regular mineral supplements.

体育投注网址Keep in mind that mineral supplements are unnecessary for most healthy adults unless your diet doesn’t provide enough to meet your daily needs. In most instances, mineral supplements aren’t a suitable replacement for dietary mineral intake.

Still, vegans体育投注网址, blood donors, pregnant women, and certain other populations may benefit from regularly supplementing with minerals.

If you plan on taking chelated minerals, you should speak with a healthcare professional beforehand.

Summary

Some individuals, such as older adults and those who have difficulty tolerating regular supplements, may benefit from chelated minerals.

Chelated minerals are those bound to a chelating agent, such as an organic or amino acid, to improve absorption.

Though they’re often said to be absorbed better than regular mineral supplements, the current research is mixed.

For certain populations, such as older adults and those with stomach issues, chelated minerals are a suitable alternative to regular minerals. However, for most healthy adults, there’s no need to choose one over the other.
