Analysis

The two-capsule serving provides 300 mg of magnesium from TRAACS buffered glycinate chelate. The form and amount fit users seeking systemic magnesium support without the very high load of 400 to 500 mg products.

Buffering can improve elemental density, but the added magnesium source and its proportion are not disclosed. That omission prevents treating the full amount as unbuffered glycinate.

Sixty servings offer a practical two-month supply. The formula is well focused, though the serving cost remains high compared with simpler chelated alternatives.

Who is it for
  • Adults seeking buffered magnesium glycinate
  • Users who prefer capsules
  • People wanting a two-month supply
Best for
  • Chelated magnesium intake
  • Moderate-to-high magnesium support
  • Focused mineral supplementation

Pros

  • Uses branded TRAACS glycinate chelate
  • Provides 300 mg of magnesium
  • Offers 60 servings
  • Avoids unnecessary active additions

Cons

  • Does not identify the buffer
  • Full excipients are missing
  • Costs more than many alternatives
  • Requires two capsules per serving

Warnings

  • The 300 mg magnesium serving may cause diarrhea, cramping, or nausea, especially when taken at once.
  • Reduced kidney function can impair magnesium clearance, so regular supplemental use requires medical guidance in that situation.
  • Magnesium can reduce absorption of levothyroxine, bisphosphonates, and certain antibiotics; follow the medicine-specific spacing interval.

Nutrient quality

90 Highest impact

Form quality is favorable and the magnesium amount is meaningful. The focused ingredient profile remains aligned with its intended use.

.

Ingredient transparency

Magnesium · 300 mg

Magnesium glycinate provides a well-absorbed form of a mineral involved in normal nervous-system regulation. The disclosed amount is meaningful, and the patented chelate gives unusually strong form assurance.

The focused formula supports one foundational relaxation pathway rather than cortisol regulation or direct neurotransmitter modulation. Its buffered design is not fully explained, but the product remains much stronger than magnesium oxide-based alternatives.

A meaningful magnesium glycinate serving supports normal muscle, nerve, and energy-related functions. The patented chelate and clear elemental amount strengthen confidence in absorption and label quality.

The formula is deliberately narrow and does not fill wider vitamin or fatty-acid gaps. Magnesium can still cause digestive discomfort in some users, although glycinate is often better tolerated than oxide.

A meaningful amount of branded magnesium glycinate may support vascular relaxation and normal cardiac rhythm. The buffered form can include less absorbable magnesium, so its quality is not as clear as an unbuffered glycinate.

The formula provides strong depth for one established mineral pathway with no unnecessary additions. Its narrow focus leaves lipid balance, cellular energy, and homocysteine regulation unaddressed.
