Vitamin Intake Calculator
Vitamins are essential for normal body function. Fat-soluble vitamins (A, D, E, K) and water-soluble B vitamins and vitamin C support immunity, energy metabolism, bone health, and cell repair.
The DiyetisyenPRO vitamin calculator personalizes daily needs by age, sex, and special conditions, with food sources listed for each vitamin.
Factors That Affect Vitamin Need
- Age and sex: Reference values differ across life stages.
- Pregnancy and breastfeeding: Higher needs for folate, B12, A, C, and others.
- Diet pattern: Vegetarian and vegan diets may raise needs for B12, D, and B2.
- Smoking and alcohol: Smoking can increase vitamin C needs; alcohol can affect B vitamins.
- Menopause: Vitamins D, K, and B6 may matter more for bone and hormonal balance.
- Intense exercise: Higher metabolism and oxidative stress can raise C, E, and B vitamin needs.
- Low sun exposure: Indoor work or limited sun raises vitamin D risk.
- Diabetes: B1, C, and D needs may be affected by glycemic control and oxidative stress.
- Thyroid disease: B12 and D monitoring supports metabolic balance.
What the DiyetisyenPRO Tool Provides
- Daily guidance for 13 vitamins: A, B1, B2, B3, B5, B6, B7, B9, B12, C, D, E, and K.
