Expert note

"Standard Vitamin C Product with Strong Brand & Quality Ratings Despite Undisclosed Source"Among standard formulation products (without special techniques like liposomal), this product offers the best price competitiveness among those that do not disclose raw material origin (most likely Chinese sourced). Excluding the undisclosed raw material origin, which is the most critical brand evaluation item in Yakalk's assessment criteria, this product scores highly on other brand evaluation items: NON-GMO extraction origin, GMP certification, and vegan-compatible (brand evaluation score: 74 points; average ~56 points). In quality evaluation, purity exceeds 90%, achieving the highest score (average ~70%). In inactive ingredient evaluation, synthetic additives such as flavoring, sweetener, and colorant are absent. Among important excipients—carboxymethylcellulose, silicon dioxide, and magnesium stearate—only magnesium stearate is present in minimal amounts. There are no additional benefit ingredients, though this is not particularly significant for a vitamin C-only product. Therefore, the inactive ingredient evaluation score is 64 points, close to average.
