What It Is
Glutamate Scavenger III is a magnesium-led formula built around Magtein® magnesium L-threonate, supplied at 2 g per serving inside a 2189 mg blend alongside valerian root, magnolia bark, and sunflower-derived phosphatidylserine. It comes in DRcap® delayed-release capsules.
Key Benefits
- Supplies 145 mg of magnesium, a mineral with a role in normal nervous system function
- Provides niacin, a B vitamin with a role in normal energy metabolism and normal nervous system function
- Delivers magnesium as L-threonate, a chelated form bound to threonic acid
- Supplies phosphatidylserine, a phospholipid and structural component of cell membranes
- Includes valerian root standardized to 0.8% valerenic acid, a botanical with a long history of traditional use
- Includes magnolia bark standardized to 98% honokiol
How It Works
Magnesium is supplied as magnesium L-threonate under the branded name Magtein®, at 2 g of the compound per serving. Magnesium is always bound to something in a supplement, and the binding partner differs between forms — here it is threonic acid rather than the more common oxide, citrate, or glycinate.
Two of the botanicals are standardized to marker compounds: valerian root to 0.8% valerenic acid, and magnolia bark to 98% honokiol. Standardization means each batch is produced to a specified content of that compound rather than varying by harvest.
Phosphatidylserine is supplied as SunPS®, a sunflower-derived form. Phosphatidylserine is often sourced from soy, so the source is worth noting.
The capsules are DRcap®, a delayed-release format made from gellan and hypromellose.

Sourcing & Quality
Three ingredients in this formula are branded, specified materials: Magtein® magnesium L-threonate, SunPS® sunflower phosphatidylserine, and DRcap® delayed-release capsules. Both botanicals are standardized — valerian to 0.8% valerenic acid and magnolia bark to 98% honokiol. The capsule is made from gellan and hypromellose, and the formula is gluten-free and plant-based.
Warnings

Frequently Asked Questions
What is in Glutamate Scavenger III?
Each 3-capsule serving supplies 10 mg of niacin, 145 mg of magnesium from magnesium L-threonate, and a 2189 mg proprietary blend. The blend contains Magtein magnesium L-threonate at 2 g per serving, valerian root standardized to 0.8% valerenic acid, magnolia bark extract standardized to 98% honokiol, and phosphatidylserine as SunPS from sunflower. The full panel is listed in the Supplement Facts above.
What form does it come in, and how many servings are in a bottle?
Glutamate Scavenger III is supplied in DRcap delayed-release capsules. A bottle contains 90 capsules and the serving size is 3 capsules, which works out to 30 servings per bottle.
What is magnesium L-threonate, and how is it different from other forms?
Magnesium in a supplement is always bound to something, and the compound it is bound to defines the form. Magnesium L-threonate is magnesium bound to threonic acid, sold here under the branded name Magtein. Other common forms include magnesium oxide, citrate, glycinate, and malate. The elemental magnesium content differs between forms, which is why the panel states both the compound weight and the magnesium within it.
Why is magnesium listed twice on the label?
They are the same ingredient counted two ways. The 145 mg figure is the elemental magnesium, listed in the upper section because magnesium has an established Daily Value. Magtein magnesium L-threonate appears again in the blend at 2 g per serving, which is the weight of the whole compound. The remainder of that 2 g is threonic acid.
Is the phosphatidylserine soy-derived?
No. It is supplied as SunPS, a sunflower-derived phosphatidylserine, as stated on the Supplement Facts panel. Phosphatidylserine is commonly sourced from soy, so the source is worth checking on any product that contains it.
What does “standardized to 98% honokiol” mean?
Honokiol is the compound magnolia bark extracts are characterized by. Standardization means each batch is produced to contain a specified percentage of that compound, so a 98% standardization is a highly concentrated extract rather than whole ground bark. Without standardization, the marker compound content of a botanical extract varies between harvests and batches.
What is a DRcap capsule?
DRcap is a delayed-release capsule made from gellan and hypromellose, both plant-derived. Delayed-release capsules are formulated to resist dissolving immediately, so the contents are released further along rather than on contact with stomach acid. It is the only other ingredient in this formula.
