Daily Vitamins: Recommended Intake, Sources & More
Vitamins and minerals are essential to health, though needs can vary based on age, gender, and other factors. Use our chart to ensure the right intake on a daily basis.
All vitamins and minerals are important for overall health and aid in countless important functions in the body. Not getting enough daily vitamins over time could lead to health problems, so it is important to know which to take.
Knowing what vitamins are needed daily can be impacted by age, gender, and health. Our comprehensive vitamins and minerals chart helps breakdown the right intake for each nutrient.
What Do Vitamins Do for Health?
Essential vitamins can be broken down into how they are absorbed in the body: Fat or water soluble.
Fat soluble vitamins include vitamins A, D, E, and K. They are absorbed and stored in fat cells in the body. Water soluble vitamins include B vitamins and vitamin C. They are typically not stored in the body, as any extra in the body can be eliminated through urine (water).
Essential vitamins help make many important functions in the body possible:
• Breaking down nutrients (protein, carbohydrate and fat) for energy
• Regulating fluid balance
• Growing and producing new cells
• Maintaining healthy muscle, nerve, bone, blood and immune systems
• Protecting cells from damage
• Preventing from birth defects during pregnancy
Vitamins are considered essential nutrients, meaning the body needs them to function and does not produce them. Thus, eating a balanced, varied diet is recommended to get all essential vitamins daily.
All vitamins have a unique function in the body and are needed in varying amounts. A single food does not provide all essential vitamins. It is generally recommended to achieve vitamin levels from natural sources eating a varied diet. Before taking a vitamin supplement, consult a healthcare professional or team.

B Vitamins
The B vitamins are composed of eight different, individual vitamins. Their functions in the body and food sources are fairly similar.
A wide variety of plant and animal-based foods provide B vitamins. Most B vitamins are needed to break down nutrients for energy and some are needed for making new cells in the body.
Most nutrient needs increase with pregnancy and breastfeeding. This is especially true for B vitamins, like folate, that are involved with making new cells and cell building blocks like DNA.
