What Is Magnesium Glycinate?

Magnesium glycinate is a chelated form of the mineral magnesium. It is made from one magnesium bound to two glycines. Both are involved in supporting efficient cellular function. Magnesium is one of the most abundant minerals in the body and is vital for the functioning of all living cells. It’s used in more than 300 enzymes. ATP (i.e., cellular energy) occurs complexed with ATP, so all enzymes utilizing or synthesizing ATP require magnesium. The same is true for enzymes that synthesize DNA and RNA, magnesium is always involved. Magnesium also plays a large role in breaking down sugars (glycolysis). Because magnesium supports the electrical functions of cells (i.e., it’s an electrolyte), muscle and nerve function rely on magnesium. Glycine was discovered in the early 1800’s. It’s name comes from the Greek word for sweet, because glycine has a sweet taste similar to sugar. Glycine is a conditional amino acid. While we can make glycine inside the body (i.e., it’s non-essential), there are circumstances where the amount we make and what we get in the diet appear to be insufficient to optimize functional health. Glycine is used to make many proteins in the body. An example is glutathione, which functions as part of cellular antioxidant defenses and detoxification. Glycine is also used in the brain as a neurotransmitter and throughout the body to make collagen. Collagen proteins are the best dietary source of glycine.  

Neurohacker’s Magnesium Glycinate Sourcing

Magnesium glycinate is used when there’s a role for both magnesium and glycine in the formula. For example, both support healthy cellular energy function. Magnesium is involved in making and using ATP and glycine supports building the antioxidant molecule glutathione, so boosts antioxidant defenses.

Magnesium glycinate has higher bioavailability than other more traditional forms of magnesium supplementation, because the two glycines act as a carrier and allow for efficient absorption (1)

Magnesium glycinate sourcing is focused on ensuring it is non-GMO, gluten-free and vegan.

Magnesium Glycinate Dosing Principles and Rationale

The Recommended Dietary Allowances for magnesium in adults varies from 310 to 420 depending upon age and gender. A majority of Americans of all ages fall somewhat short of this amount. Supplying even a low dose of magnesium can help close the gap. Magnesium glycinate contains about 14% elemental magnesium by mass (the other 86% is glycine), so the complex provides far more glycine than magnesium. An average adult requires about 15 grams of glycine daily. About 2-3 grams is made in the body; diet must provide the rest. (2) Magnesium glycinate is generally considered to be dose-dependent (see Neurohacker Dosing Principles) in the range it’s commonly dosed. We generally dose it in small amounts to augment dietary intake of both magnesium and glycine.

Potassium as Tripotassium Citrate

Potassium Citrate Common Names

Tripotassium Citrate | Potassium | Citrate | Citric Acid

Top Benefits of Potassium Citrate

  • Supports electrolyte balance*
  • Supports cellular energy*
  • Supports neuronal function*
  • Supports muscle function*

What Is Potassium Citrate?

Tripotassium citrate is a chelated form of the mineral potassium, with three potassium ions bound to a single citrate molecule. Both molecules are involved in supporting efficient cellular energy production. Potassium is one of the most abundant minerals in the body and is vital for the functioning of all living cells. Its main role is as an intracellular electrolyte (sodium is the main extracellular electrolyte). Potassium is needed for electrolyte balance, which supports the electrical functions of cells. Citrate is a salt of citric acid, a compound that was first identified in lemon juice, but is found in all citrus fruits. Citrate is an intermediate in the citric acid cycle (also called the Krebs cycle), a circular pathway that helps turn food into energy (i.e., ATP) and build important biomolecules. Adding intermediates like citrate into this cycle helps upregulate the flux (i.e., the cycle can essentially spin faster). Citrate is also a vital component of bone. 

Neurohacker’s Potassium Citrate Sourcing

We opt to use the citrate sale of potassium, instead of a different form of potassium, when both potassium and citrate play a role supporting pathways or processes in a formulation.

Potassium citrate sourcing is focused on ensuring it is non-GMO, gluten-free and vegan.

Tripotassium Citrate Dosing Principles and Rationale

Tripotassium citrate is used primarily as a source of citrate, an important Krebs cycle and mitochondrial nutrient. We dose it in small amounts to augment dietary intake. The adequate intake (AI) for potassium in adults is 3400 mg for men and 2600mg for women. Supplements will typically contain 99 mg or less per serving because of certain FDA constraints with potassium dosing. This amount would not be sufficient to correct issues with potassium intake.

Potassium Citrate Key Mechanisms

  • Main positively charged ion in intracellular fluid (1, 2)
  • Along with sodium, potassium creates an electrochemical gradient across cell membranes known as the membrane potential (1, 2)
  • Essential for nerve impulse transmission, muscle contraction and heart function (2)
  • Potassium is required for the activity of a few enzymes including pyruvate kinase (catalyzes the final step of glycolysis) (3)
  • Supports insulin secretion (4)
  • Regulates blood flow and blood pressure (4, 5, 6)
  • Protects kidney function (7, 8)
