Some people just need proper treatment and help. Taking such vitamins is not going to solve these problems. And what's with citing lazada msia? S'pore also has tons of these if you know where to look.
Seems to be most affordable B-complex vitamin pills. Shopee also sells. They also have direct website, can do collection at KSL Mall.
