我在 B-Complex 50 與 Big 50（長效型） 中猶疑

B-Complex 50 成分表：
Thiamin (B1) as thiamin mononitrate 50 mg
Riboflavin (B2) 50 mg
Niacin (B3) as niacinamide 50 mg
Vitamin B6 as pyridoxine hydrochloride 50 mg
Folate,Folic Acid,Folacin 400 mcg
Vitamin B12 cyanocobalamin 50 mcg
Biotin 50 mcg
Pantothenic acid as calcium d-pantothenate 50 mg
Choline Bitartrate 50 mg
Inositol 50 mg
Para-Aminobenzoic Acid 50 mg


Big 50 成分表：
Thiamin (B1) as thiamin mononitrate 50 mg
Riboflavin (B2) 50 mg
Niacin (B3) as niacinamide 50 mg
Vitamin B6 as pyridoxine hydrochloride 50 mg
Folate,Folic Acid,Folacin 400 mcg
Vitamin B12 cyanocobalamin 50 mcg
Biotin 50 mcg
Pantothenic acid as calcium d-pantothenate 50 mg
Choline Bitartrate 50 mg
Inositol 50 mg
Para-Aminobenzoic Acid 30 mg


所以，只有差別在 Para-Aminobenzoic Acid的含量
請問這事甚麼?
"長效型"都比較貴，買過的人覺得有比較值嗎?
