강황, 포도씨 및 비산성 비타민 C가 함유된 리포솜 케르세틴 1000mg – 비건 – 소프트젤 60정

Among standard-form products (without special techniques such as liposomal delivery), this product has poor price competitiveness as its greatest disadvantage. Compared to competitively priced products with undisclosed raw material origins (likely mostly Chinese sourced) in the category most critical to Yak-Al's brand evaluation—raw material origin disclosure—this product is over 30 times more expensive. GMP certification status is unknown, and in the purity category of quality assessment, the purity is approximately 30%, which is lower than the general standard-form purity average of approximately 60%. In addition to vitamin C, this product contains a high proportion of quercetin, a bioflavonoid known to support vitamin C absorption. However, the pure vitamin C content is 250 mg per tablet, which is less than the basic amount found in vitamin C products (1000 mg), so a large daily intake would be required to meet the standard daily nutritional reference value of 1000% for vitamin C (1000 mg). Since other Yak-Al products are available with balanced vitamin C and bioflavonoids at competitive prices, this product is not recommended.
