Vitamin Kya Hote Hain? (विटामिन की परिभाषा)
Vitamin aise organic micronutrients hote hain jo hamare sharir ko sahi tarike se kaam karne ke liye bahut kam matra me chahiye hote hain. Ye body khud se ya to bana nahi pati ya phir paryapt matra me nahi bana pati, isliye hume vitamins food (diet) se lene padte hain.
