Analysis

The three-softgel serving provides 400 mg of magnesium from citrate, glycinate, and malate. Avoiding oxide gives the blend better expected systemic absorption than many high-dose competitors.

The contribution from each form is not disclosed, so users cannot know whether glycinate or citrate leads the blend. Two grams of fat and 20 calories reflect the softgel delivery rather than added nutritional value.

Thirty servings and moderate cost are reasonable for a multi-form softgel. The full 400 mg amount may still loosen stools, and the three-softgel burden reduces flexibility.

Who is it for
  • Adults seeking an oxide-free magnesium blend
  • Users who prefer softgels
  • People wanting citrate, glycinate, and malate together
Best for
  • Multi-form magnesium support
  • An oxide-free active profile
  • Substantial elemental intake

Pros

  • Uses citrate, glycinate, and malate
  • Avoids magnesium oxide
  • Provides 400 mg of magnesium
  • Keeps the active formula focused

Cons

  • Does not disclose form proportions
  • Requires three softgels
  • Adds 2 g of fat and 20 calories
  • Offers only 30 servings

Warnings

  • The 400 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.

Magnesium · 400 mg

A substantial magnesium amount uses glycinate, malate, and citrate forms with good absorption potential. The blend supports foundational energy, nerve, and muscle functions.

The single-mineral focus limits breadth but provides strong depth for people seeking magnesium support. A full serving may loosen stools or cause digestive discomfort, particularly because citrate is included.

Magnesium · 400 mg

The therapeutic magnesium amount uses citrate, glycinate, and malate forms with good absorption potential. That combination can support ATP-dependent metabolism and muscle function when magnesium intake is inadequate.

The product remains a single-pathway mineral supplement rather than a broad energy formula. A full serving may cause loose stools or abdominal discomfort in sensitive users because supplemental magnesium has an osmotic effect.

Magnesium · 400 mg

A substantial magnesium amount may support physical relaxation and nervous-system resilience when intake is low. Glycinate, malate, and citrate provide a stronger absorption profile than oxide-based blends.

The three forms are not individually quantified and do not add a distinct adaptogenic or direct-calming pathway. The substantial supplemental amount may cause loose stools or abdominal discomfort.

Magnesium glycinate, malate, and citrate provide a meaningful amount with strong absorption potential. Clear disclosure supports confidence in its contribution to bone mineral structure and vitamin D activation.

The formula remains limited to magnesium and does not cover calcium, vitamin D, vitamin K, or collagen. Its premium forms give the narrow pathway good depth without unnecessary actives.

Three magnesium forms provides foundational support for vascular tone, normal heart rhythm, and blood-pressure regulation when magnesium intake is low. It does not cover lipid management, nitric-oxide production, or cellular energy.

The 400 mg amount is substantial and uses malate, citrate, and glycinate forms. High supplemental magnesium may cause diarrhea or abdominal discomfort, especially in sensitive users.

The blend combines glycinate and malate with citrate, giving it strong absorption potential. The label presents a therapeutic elemental magnesium amount, but no patented or fully reacted chelation standard is identified. Its serving cost is favorable for the form quality, while the formula offers no named uptake cofactor.
