Vitamin D3 liquid 3,000 IU provides 3,000 IU of natural vitamin D3 per drop. D3 is the most important and effective form of vitamin D for humans. In the body, it has the function of a prohormone and is converted to the active hormone calcitriol via an intermediate stage. With 75 mcg (3,000 IU) of vitamin D3 per drop, Vitaplex Vitamin D Liquid offers one of the highest concentrations. Thus, the recommended daily dose can be achieved with just a single drop. Vitamin D3 is dissolved in an extract of coconut oil and dissolved with a high proportion of medium-chain triglycerides (63% MCTs). This is easily absorbed by the body without any further digestive steps and thus has excellent bioavailability. Notes: Food supplements are not a substitute for a varied and balanced diet and a healthy lifestyle. Store food supplements out of the reach of small children. Do not exceed the recommended daily intake.
