- 800–2000 IU per day year-round if adequate synthesis of Vitamin D during summer is not ensured.
- For those over 65 years of age: 800–2000 IU per day year-round, as skin synthesis of Vitamin D is reduced in this age group.

Adequate intake of Vitamin D is crucial for individuals with bone diseases such as:
- Osteoporosis
- Osteopenia (a precursor to osteoporosis, characterized by reduced bone minerals)
- Osteomalacia (insufficient bone mineralization due to Vitamin D deficiency, leading to impaired calcium absorption from the intestines and resulting in calcium deficiency).
Higher doses of Vitamin D are also important for individuals with kidney diseases. Taking Diferol alongside sunlight exposure does not pose a risk of overdose.
