Berocca is a supplement that is effective in enhancing physical energy and mental performance, claims its website. It is also used to treat and prevent vitamin deficiencies, says WebMD. The tablet dissolves when mixed with a glass of water, and it contains calcium, magnesium, zinc and other vitamins and minerals.
Taking Berocca may cause side effects, including headache, upset stomach and unpleasant taste, says Everyday Health. Do not take Berocca with dairy products or additional calcium supplements, as too much calcium causes difficulty absorbing nutrients. Ask a doctor if Berocca is safe with prescribed medications to avoid interactions. This supplement may interact with antibiotics, blood pressure medicines and NSAIDs.
