Magnesi-OM powder

Magnesi-OM discloses individual ingredient amounts transparently: 310 mg magnesium from a chelate blend (magnesium gluconate, magnesium acetyl taurinate, magnesium citrate) and 112 mg L-theanine. The magnesium dose is moderate (70% DV) and uses bioavailable forms—acetyl taurinate and citrate are preferred forms per the rubric, though the exact ratio within the blend is not disclosed. L-theanine at 112 mg is a clinically studied dose for relaxation. However, the product lacks third-party certification (NSF Certified for Sport, Informed Sport, or USP) to independently verify batch consistency and purity, despite Moon Juice's claim of third-party testing. No clinical studies on the combined formula or customer efficacy data are present in the source corpus. The formulation is sound but unverified at the batch level, placing it in the mixed-to-strong range.

Magnesi-OM demonstrates strong ingredient integrity with several positive signals. The magnesium blend uses three bioavailable forms—magnesium gluconate, magnesium acetyl taurinate, and magnesium citrate —all preferred chelated/organic forms that signal quality over cost-cutting oxide formulations. L-Theanine at 112 mg is a clean, well-researched amino acid with no safety concerns. The product is vegan and non-GMO certified, sugar-free, and third-party tested for quality and safety in a GMP-certified facility with compliance to California Proposition 65 heavy-metal limits. However, the score is moderated because the retrieved sources do not disclose specific sourcing origins for individual ingredients (e.g., where magnesium is mined, where L-Theanine is sourced), and no independent third-party certifications like NSF Sport or Clean Label Project testing are mentioned in the corpus. The formulation itself is clean—no artificial sweeteners, colors, or unnecessary fillers are evident—but sourcing transparency remains a gap.

Moon Juice demonstrates a real compliance pathway with meaningful transparency gaps. The brand discloses full individual ingredient amounts for Magnesi-OM (Magnesium 310 mg from a named chelate blend, L-Theanine 112 mg), claims GMP-certified manufacturing, and reports third-party testing for bio-identity, purity, potency, microbiological content, residual solvents, heavy metals, and pesticides. The brand has a clean FDA/CAERS record with no recalls or enforcement history. However, Moon Juice holds no NSF Certified for Sport, Informed Sport, or USP certifications; the Non-GMO and Vegan claims are secondary certifications. The brand is distributed through Sephora Canada and physical retail locations, adding retail accountability. The NonToxicChecker assessment notes "a need for greater transparency" and absence of formal certifications on record. Full dose disclosure and clean regulatory history place this in the solid mixed band; lack of NSF-class independent formula verification and secondary-only certifications prevent entry into the strong band (14+).

Moon Juice Magnesi-Om is priced at $1.47/serving for 310 mg magnesium + 112 mg L-theanine. The product claims third-party testing and traceable sourcing, which are legitimate quality signals. However, the value proposition is mixed. The magnesium dose (310 mg) is modest relative to clinical recommendations (typically 300–400 mg daily), and the L-theanine addition (112 mg) is a minor component. Comparable magnesium supplements with similar bioavailable forms and third-party testing (e.g., Thorne Magnesium Bisglycinate, Nutricost Magnesium Glycinate) typically cost $0.60–$1.20/serving at equivalent quality tiers. Moon Juice's premium positioning reflects branding and packaging rather than demonstrably superior formulation—the three chelated magnesium forms are a legitimate advantage, but not unique in the certified supplement space. The product lacks independent third-party certifications (NSF Sport, Informed Sport, USP) [source 917efe24-e041-4cc8-bdee-69469c761054 mentions third-party testing but does not specify which certifications], which would justify the price premium more clearly. Subscription discounts are available (up to 35% off), reducing subscription-trap concerns, but the one-time price remains notably higher than certified peers with equivalent active doses. This is reasonable but not strong value—you are paying a meaningful premium for brand positioning and taste/convenience (powder format with berry flavor) rather than for clinically superior formulation or independent certification credentials.

Moon Juice Magnesi-Om demonstrates mostly positive customer sentiment with established community validation, but faces recurring minor friction points that prevent a higher score. The brand earns a 3.9/5 rating across 73 reviews with 72% recommending to a friend, indicating solid baseline satisfaction. Editorial reviews are consistently positive: a dietitian notes the product contains "high quality ingredients and is third party tested" with "evidence-based" formulation, and another reviewer praised the brand's "100% traceable ingredients" and responsible sourcing. However, the broader Moon Juice product line shows polarized reception: while devotees praise Magnesi-Om specifically for "tangible sleep" benefits, the brand faces recurring complaints including "polarizing, earthy powder flavors," "inconsistent supplement efficacy," and "GI-disruptive magnesium for some". These are minor deductions from a positive baseline rather than dominant signals—the product is specifically praised while broader brand complaints reflect lifestyle-vs.-ingredient-aware audience polarization. No subscription, cancellation, or service failures were found in the source corpus. The score reflects a mostly-positive, grounded community with minor but real taste/efficacy friction.
