Experts advise intaking Zincovit in the morning because, after excretion, our body functions actively in the daytime. In addition to this, consuming nutritional supplements in the morning routine increases metabolism. Hence you can take a Zincovit tablet at night as well but prefer to intake in the morning. However, there is no specific duration; you can take it every day because the Zincovit tablet is made as per RDA (Recommended Dietary Allowances).
