Magnesi-Om Magnesium Powder with L-Theanine for Relaxation, Natural, Organic Mixed Berry or Lemon Flavor

Six-dimension breakdown

Why this scored 68/100

Magnesi-Om is Moon Juice's flagship magnesium formula — a three-magnesium blend (gluconate + citrate + acetyl taurate) plus L-theanine and monk fruit for flavoring. Moon Juice is a Los Angeles-based adaptogen and wellness brand (Amanda Chantal Bacon, founded 2011). The formulation is thoughtful: magnesium acetyl taurate is a specific form with limited human data (proposed to cross the BBB, some rodent studies for anxiety) and citrate + gluconate are well-absorbed general-purpose forms. Delivers 310mg elemental magnesium per serving plus 200mg L-theanine (a defensible calming dose per Kimura 2007). L-theanine at 200mg has a real evidence base for reduced stress and improved sleep onset. Held to Standard by (1) the magnesium acetyl taurate marketing outrunning the specific-form evidence, (2) no per-lot COA published, and (3) premium price without proportional independent verification. A defensible pick for a magnesium-plus-calm formula.

Evidence & sources

The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.

Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

How to read the Evidence dimension

• 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
• 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
• 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
• 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
• 0–19: No credible evidence base or unverifiable claims.
