Nick - I've been banging away at the drum over the reason why the glycinate form is useful for so many it seems almost weekly in various posts. I'm glad you connected with this one.
See the following explanation from a previous post. Not that the WW form isn't useful. It definitely is as is the topical form called 'magnesium oil'... as transdermal deliver is quick and efficient and also doesn't have to be broken down by stomach acid.
The magnesium story is a very large 'chapter' in what's critical for optimal health. Because there are so many variations in situations that leave many of us vulnerable to low intracellular levels of magnesium - especially in heart cells - it becomes important to attempt to understand as much as possible and try to sort out what fits for your biochemical uniqueness.
Shortly, I'll be posting a list of 'one-liners' that will serve to emphasize the importance of magnesium for health and for afibbers, especially... mostly as a review for those who have not slugged through all this as the story unfolded years ago.
Advantages of Chelated Minerals

In a recent teleconference featuring a presentation by Sharon R. Price, Ph.D., CN , the advantages of chelated minerals were discussed. While it was not the presentation topic, some time was spent to emphasize the need to recognize that in order to be absorbed and assimilated to any degree of measured or calculable benefit, it is worth knowing why chelated minerals are a better choice. Reference was made to Albion chelated minerals. This is the company that has patents on chelating minerals.
magnesium glycinate (for one) with which we are familiar. [Albion did not sponsor the teleconference, but the nutritionists speaking were using minerals chelated by the Albion process.]
After listening, I reflected on the potential side effects caused by a mix of ionic minerals together as evidenced by some symptoms many afibbers report.
We already know to use magnesium glycinate, and for about a year, I was using a chelated potassium product which I do believe was much better in reducing ectopy. It was Solgars Amino Acid Potassium Complex in the form of potassium glycinate which is an Albion chelate. Hans has it on his website and as soon as I finish the potassium citrate Im using, Im going back to the chelated version. I dont even know why I stopped! [they are listed as $5.82 /100 tablets without the discount]. What a bargain!
We may want to check all the forms of minerals we take after reading this thread.

Here are some of the comments from the presentation and then a reference page.
- Therapeutic doses of any mineral must be accomplished with chelated minerals. Chelated minerals are designed to the ability to survive stomach and will break down directly in the intestine, ready to enter the blood stream immediately, unlike ionic minerals that are split in the gut unless chelated. There is no interference with hydrochloric acid (HCl) or food fiber. You take them, they pass through the stomach, all intact, together and, boom they are in the blood.
- The problem arises when multiple (unchelated) ionic minerals are consumed together and then break down into a chemical experiment going on in the stomach, then there is no reliable calculation as to how much of what is actually bioavailable and utilized.
You can go to Albions website [
www.albion-an.com] and learn more about the importance of chelated minerals but following are some highlights. Specific mention in the teleconference was made to the wheel showing which minerals tend toward antagonism with each other and need to be monitor for correct balance or ratios
like calcium to magnesium, sodium to potassium, chromium to vanadium, copper to zinc. Its worth viewing the wheel.
Many minerals with inversion to the standard ratio indicate a route to checking for disease processes; ie, if sodium is high look to inflammation and allergy; with poor digestion and low B vitamins, Calcium is elevated relative to magnesium.
Natural HCl in the stomach is used to make food minerals available. [chelated minerals do not benefit from HCl- as previously stated.]
Chelated minerals provide us with the essential requirement of packaging our minerals in a way that allows them to be absorbed by the body without going through extra steps to do so.
BENEFITS
Improved Absorption
Increased Tolerability
Less Absorption Interference from Foods
Guaranteed Purity and Stability
Guaranteed pH Stability
WHAT IS A CHELATED MINERAL, AND WHY IS IT IMPORTANT
Chelated minerals are minerals, such as zinc, manganese, magnesium, copper, iron, or calcium that are surrounded by amino acids, which are bonded in a stable form to the mineral. In the body's natural process of digestion, amino acids are used to naturally chelate minerals and help transport them across the intestinal wall. If you think of a mineral as being essentially an insoluble rock, the process of chelation helps to convert the mineral and hide it in an amino acid coating that makes it usable by the body. This essentially makes it bioavailable. According to Albion Laboratories, "Bioavailability is the amount of a substance that is absorbed and available for metabolic use by the body once it is ingested."
WHY IS SUPPLEMENTATION WITH MINERALS IMPORTANT?
It is true we live in a wealthy nation that should be able to afford the best nutrition for its inhabitants. However, it is perplexing that people still use this fact to support the theory that vitamin or mineral deficiencies are rare...especially when one of the most common diseases linked to Westernization, osteoporosis, comes from Calcium deficiency!! Additionally, there are many more illnesses that are common in the Western world that have nutritional links supported by solid science. One example of a mineral deficiency that affects our health is Zinc deficiency. It has been well documented, and recently publicized, that even a minor deficiency in Zinc inhibits healthy immune function. It is clear that we should be radically changing our diets to provide all the necessary vitamins and minerals. At the very least, we should supplement with forms that are bioavailable.
Deficiencies or imbalances in certain minerals can affect the following body systems:
1. Immune System: Cu, Zn, Fe, Se
2. Energy Production: Mg, P, Mn
3. Hormone System: Fe, Mn, Zn, Cu, Mg, K
4. Vitamin Production: Co
5. Blood Production: Cu, Fe
6. Enzyme Systems: Zn, Cu, K, Mn, Mg, Fe, Ca, Mo
7. Skeletal System: Ca, Mg, Zn, Mn, B, P
8. Reproduction: P, Cu, K, Mn, Zn, Mg

THE "OTHER HALF" OF MINERALS
Much debate exists over the form that a mineral comes in, or as Albion Laboratories has called it, the "other half" (or ligand) of a mineral. A ligand is the amino acid to which minerals are often bound to in the chelating process. It may seem strange that so much controversy is involved with this "other half" when the benefit we are mostly interested in is from the mineral! The controversy, it turns out, is important because the "other half" of a mineral can influence its effectiveness, including factors such as bioavailability, tolerability, safety, retention in the tissue, and its chemical interactions. Here are some of the questions that can be encountered when looking at the mineral form:
Is glycine or picolinate a better ligand for the chelation of minerals?
Glycine is used in the Albion Laboratories manufacturing process of creating a chelated mineral. The question of what is the best ligand for a mineral is a common question, as picolinates are used often by companies claiming to make chelated minerals, whereas Albion uses glycine. The first issue in addressing this question is how each of these ligands affect the bioavailability of the mineral. Because glycine is metabolized by the body after it is absorbed, and the picolinate is not metabolized after absorption, the glycine would perform better in metabolism. The fact that glycine is used nutritionally, and picolinate is treated as a waste product for the body is also important. In studies regarding the effectiveness of picolinate as a chelating ligand for zinc, it has been found that the picolinates do not enhance absorption of zinc over other zinc forms (citrate or sulfate). The picolinates even went so far as to increase the excretion of supplemental zinc and endogenous zinc from the body as well as reducing the tissue retention in animals fed zinc picolinate.
The question of picolinates vs. glycine is an important example not only for bioavailability, but also for nutritional functionality. The use of picolinate as a chelating agent with zinc is an excellent example of the difference between a simple chelate, and a "nutritionally functional" chelate. This is because the use of picolinates makes good chelating agents because they make zinc absorb well into the body, however they are not "nutritionally functional" because they promote the excretion (and not use) of zinc once it is in the body.
Glycine, however, has important metabolic functions in the body, and research supports its use as a safe nutritionally functioning chelating agent. Glycine helps to preserve muscle mass. It is an essential component in the synthesis of creatine, which helps prevent liver damage due to alcohol abuse, and prevents ulcer-formation. Glycine also plays important roles in the central nervous system (CNS), the immune system, energy production, and the maintenance of a healthy prostate.
How do Glycine Amino Acid Chelates perform versus Salts, Citrates, Krebs-Cycle Complexes, or Bran Chelates in terms of Bioavailability and GI Tolerance?
Salts
Salts are the usual form that minerals are found in multivitamin and mineral supplements. Depending on the mineral, and other digestive factors, their bioavailability can be poor to adequate, and their GI tolerance can be poor to adequate.
Citrates
Citrate bioavailability can be poor to very good, and their GI tolerance can be poor to adequate.
Krebs-Cycle Complexes
Krebs-Cycle Complexes do not have the same stable bonding of chelates, only exhibiting weak ionic or hydrogen bonds, which do not increase their bioavailability. Theoretically, their bioavailability should be low, and their GI tolerance should be low, but there is no data on these factors to say for certain.
Glycine Amino Acid Chelates
Albion Laboratories holds the patents on the processes that create the nutritionally functional amino acid chelates made with glycine. Their bioavailability is very good and their GI tolerance is very good.
THE AUTHENTIC CHELATES
The National Nutritional Food Association (NNFA) created a definition of what an Amino Acid Chelate is in 1996; currently, Albion chelates are the only known chelates to meet the NNFA definition:
Metal Amino Acid Chelate is the product resulting from the reaction of a metal ion from a soluble metal salt with amino acids with a mole ratio of one mole of metal to one to three (preferably two) moles of amino acids to form coordinate covalent bonds. The average molecular weight of the hydrolyzed amino acids must be about 150 AMU (Atomic Mass Units) and the resulting chelate must not exceed 800 AMU. The minimum elemental metal content must be declared. It will be declared as a METAL amino acid chelate: e.g. Copper amino acid chelate.
-Adapted by the NNFA Board of Directors, July 1996
In order for chelation to occur, the following minimum requirements must be met:
The same metal ion.
The ligand must form a heterocyclic ring with the metal as the closing member of the ring.
It must be sterically possible to chelate the metal.
The molar ratio of the ligand to the metal must be at least 1:1
The above requirements, however, do not guarantee that a chelate is nutritionally functional. For a nutritionally functional chelate, the following further requirements must be met:
The chelate must have a molecular weight less than 1000 daltons.
The chelate must be electrically neutral. The chelate must not be complexed with an easily ionizable anion, such as a halogen or a sulfate group; the ligand must satisfy both the oxidative state and a coordination number of the metal atom.
The chelate must have a high enough stability constant to avoid competitive chemical interactions in the gut prior to absorption.
The ligand must be easily metabolized.
In summary, Albion Mineral Chelates are the mineral chelates, which can most closely mimic the body's natural chelation process. These chelates allow for the metabolization of mineral ligands. All Albion's processes are patented, and Albion has invested heavily in the research of its minerals for many years.
SUGGESTED USE AND SAFETY
Mineral Chelates can be taken and used just like regular multivitamins. The added benefits are: better bioavailability, higher tolerability, and less toxicity. Because chelates are easily absorbed by our bodies, and there are less problems with food or other nutrient interactions and they do not cause gastrointestinal distress (as found with most regular multivitamins and minerals), chelated minerals may be taken with a greater degree of trust and convenience throughout the day.
