Year-round nutritional consistency matters most
Vitamin Requirements by Age Group
Each age group has distinct nutritional requirements. Discover what vitamins and minerals are essential for healthy development and maintenance at every life stage.
Infants (0–12 months)
Newborns and infants require breast milk or formula as their primary nutrition source. Essential nutrients include Vitamin D for bone development, iron for cognitive growth, and zinc for immune function. Vitamin K is administered at birth to prevent bleeding disorders.
- Vitamin D: 400 IU daily
- Iron: 0.27 mg daily (breast milk)
- Zinc: 2 mg daily
Toddlers & Preschoolers (1–5 years)
As children transition to solid foods, their nutritional needs expand. Calcium and Vitamin D are crucial for bone growth, while iron supports brain development. B vitamins help convert food into energy for active play and learning.
- Calcium: 700–1000 mg daily
- Vitamin D: 600 IU daily
- Iron: 7–10 mg daily
School-Age Children (6–13 years)
Growing bodies and active minds require consistent nutrient intake. Protein supports muscle development, B vitamins fuel concentration and learning, and antioxidant vitamins protect against oxidative stress from increased activity.
- Vitamin A: 600–700 mcg daily
- Vitamin C: 45–50 mg daily
- Calcium: 1000–1300 mg daily
Teenagers (14–18 years)
Adolescent bodies experience rapid growth and hormonal changes. Peak bone mass accumulation occurs during teenage years, making calcium and Vitamin D critical. Iron needs increase, especially for menstruating females.
- Calcium: 1300 mg daily
- Iron (females): 15 mg daily
- Vitamin B12: 2.4 mcg daily
Adults (19–50 years)
Adult nutrition focuses on maintenance and prevention. Antioxidant vitamins support cellular health, while B vitamins manage energy metabolism and stress response. Vitamin D becomes increasingly important for bone density and immune function.
- Vitamin D: 600–800 IU daily
- Vitamin B6: 1.3–1.7 mg daily
- Folate: 400 mcg daily
Older Adults (51+ years)
Senior nutrition addresses age-related changes in nutrient absorption and metabolic rate. Calcium and Vitamin D are essential for maintaining bone strength. Vitamin B12 absorption decreases, requiring higher intake or supplemental forms.
- Vitamin B12: 2.4 mcg (fortified sources)
- Vitamin D: 800–1000 IU daily
- Calcium: 1000–1200 mg daily
Why Daily Vitamin Intake Matters at Every Stage
Vitamins and minerals are fundamental to human health. They support energy production, immune function, bone strength, cognitive development, and cellular repair. Each life stage brings unique demands on the body, requiring careful nutritional planning.
During childhood and adolescence, adequate nutrition directly influences growth, learning, and physical development. In adulthood, consistent vitamin intake helps maintain energy, support reproductive health, and prevent chronic wellness challenges. For older adults, micronutrient absorption changes, making targeted nutrition increasingly important.
Food sources remain the foundation of healthy nutrition. However, modern lifestyles, dietary restrictions, and individual absorption differences mean many people benefit from understanding their specific requirements. This guide helps you identify what your body needs and how to achieve nutritional balance through informed dietary choices.
Energy & Metabolism
B vitamins convert food into usable energy at every age
Immune Support
Vitamins A, C, D, and zinc strengthen natural defences
Bone Strength
Calcium and Vitamin D work together for skeletal health
Brain Function
Choline, B12, and folate support cognitive development
Essential Vitamins & Minerals Explained
Understanding what each vitamin does and why it matters helps you make informed choices about your nutrition at any age.
Vitamin A
Role: Vision, immune function, skin health, and cellular growth
Sources: Sweet potatoes, carrots, spinach, kale, liver, eggs
Note: Fat-soluble; best absorbed with dietary fat. Excess intake from supplements can be harmful
Vitamin B Complex
Role: Energy production, nervous system function, and DNA synthesis
Sources: Whole grains, legumes, meat, fish, eggs, dairy, leafy greens
Note: Eight distinct vitamins; B12 especially important for vegans and older adults
Vitamin C
Role: Antioxidant, collagen formation, and immune support
Sources: Citrus fruits, berries, peppers, broccoli, tomatoes, kiwi
Note: Water-soluble; not stored in the body, so daily intake is essential
Vitamin D
Role: Calcium absorption, bone health, immune regulation, and mood support
Sources: Fatty fish, egg yolks, fortified milk, sunlight exposure
Note: Synthesis from sunlight decreases with age and latitude; deficiency is common
Calcium
Role: Bone and tooth structure, muscle function, and nerve transmission
Sources: Dairy products, leafy greens, fortified plant milks, almonds, sardines
Note: Peak bone mass peaks by age 30; adequate intake throughout life is protective
Iron & Zinc
Role: Oxygen transport, immune function, wound healing, and enzyme activity
Sources: Red meat, poultry, beans, nuts, seeds, oysters, fortified cereals
Note: Iron needs increase during menstruation; plant sources less bioavailable than animal sources
How to Determine Your Daily Vitamin Requirements
Follow these evidence-based steps to assess your personal nutritional needs and create a sustainable plan.
Identify Your Age Group
Find your specific life stage above to understand baseline requirements. Nutritional needs vary significantly by age, so this is your starting point.
Assess Your Diet Quality
Review your typical food intake. Diverse, whole-food diets rich in colourful vegetables, fruits, proteins, and whole grains typically provide most essential vitamins naturally.
Consider Special Factors
Account for dietary restrictions, health conditions, medications, lifestyle, and environmental factors. Vegans may need additional B12; people with limited sun exposure need more Vitamin D.
Monitor & Adjust
Track your energy, mood, digestion, and overall wellness. Get regular blood work done annually. Adjust your supplement regimen based on results and how you feel.

Frequently Asked Questions
Got questions? We've got answers about supplementation and personalized nutrition.
How long does it take to see results from supplements?
Results vary depending on the supplement and individual factors. Some people notice energy improvements within 2-4 weeks, while others may need 8-12 weeks for joint health or skin benefits. Consistency and proper dosage are key. We recommend tracking your progress monthly.
Are supplements safe to take with medications?
Some supplements can interact with medications. Always consult your healthcare provider or pharmacist before starting any new supplement regimen, especially if you're on blood thinners, diabetes medications, or other prescriptions. Your safety is our priority.
What's the difference between synthetic and natural supplements?
Natural supplements are derived from whole food sources, while synthetic supplements are lab-created. Both can be effective, but natural supplements often retain additional beneficial compounds. Choose based on your values, absorption rates, and budget. Quality matters more than the source.
How do I know if I have a nutrient deficiency?
Common signs include fatigue, brain fog, weak immunity, hair loss, or digestive issues. The best way to know for certain is through blood work ordered by your doctor. Our assessment tool can help identify potential deficiencies based on your lifestyle, but professional testing is always recommended.
Can I take too many supplements?
Yes. Fat-soluble vitamins (A, D, E, K) can accumulate in your body and become toxic at high doses. Water-soluble vitamins are safer but excess amounts are typically excreted. Follow recommended dosages and avoid "more is better" thinking. Our personalized plans are designed to meet your needs, not exceed them.
