How Bio D3 Strong works

Cholecalciferol (vitamin D3) is converted in the body to active vitamin D, which increases intestinal absorption of calcium and phosphate. It helps maintain normal blood calcium levels and supports bone mineralization and muscle function.

How to take Bio D3 Strong

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.

Missed dose and overdose

If you miss a dose

If you miss a dose of Bio-D3 Strong Soft Gelatin Capsule, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and resume your regular schedule. Do not take extra to make up for a missed dose.

If you take too much

An overdose of this medicine may be harmful — seek medical advice immediately. It can raise blood calcium dangerously, causing thirst, frequent urination, vomiting, confusion and kidney damage. It can cause vomiting, stomach pain and, with some minerals, damage over the longer term. It can cause vomiting and stomach pain, and with iron can be dangerous, especially in children. It is unlikely to cause serious harm, because the body passes surplus B vitamins out in the urine. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
