Expert note

"Superior Transparency and Quality with Premium Pricing"Among standard formulation products (without special techniques like liposomal), this product stands out as one of the rare options that transparently discloses ingredient origin—a critical evaluation criterion for Yakal's brand assessment (most standard products do not disclose this). Additionally, it meets top-tier brand evaluation standards with NON-GMO certification, GMP mark presence, and 100% vegan compliance, earning one of the few maximum brand assessment scores of 95 points. In quality evaluation, it received top marks for purity at 90% or higher. In auxiliary ingredient assessment, it contains only minimal excipients—no carboxymethyl cellulose, silicon dioxide, or magnesium stearate—earning maximum points. Price-wise, it costs approximately double compared to Yakal's pick products without disclosed origin (roughly 100 yen difference at 1000% daily intake nutrient reference basis). Given the rarity of products with disclosed ingredient origin, the consumer value is substantial and this product is recommended.
