Fat-soluble vitamins are the type of vitamins that can be stored in your body's fatty tissues and can be utilized later. So you do not need to consume them regularly as frequent intake can do the needful. Some of the commonly known fat-soluble vitamins include A, D, E and K.
- Vitamin A is needed for a range of different aspects of one’s health. This covers clear vision, immunity, reproduction, and growth. Adequate amount of vitamin A intake may also prevent cancer and skin problems. Carrots, spinach, liver, dairy, sweet potatoes, and fish are the best sources of vitamin A.
- Vitamin E is also an essential fat-soluble vitamin that protects your body from cell damage and boosts immunity. Wheat gram, almonds, and sunflower seeds are the best sources of vitamin E.
- Vitamin D ensures normal calcium absorption while also contributing to normal brain function. Milk, salmon, tuna, sunflower seeds, and fish oil contains a high amount of vitamin D.
- Vitamin K plays a major role in helping the blood clot. This can prevent excessive bleeding. There are two types of vitamin K; K1 & K2. Green leafy vegetables including collard and turnip greens, kale, spinach, broccoli, Brussels sprouts, cabbage and lettuces contain high amounts of vitamin K.

Water-soluble vitamins must be consumed regularly to fulfill the body's needs, as they cannot be stored in the body. Some examples of such vitamins include B-complex and C.
- Vitamin B-complex includes many vitamins, including B-1, B-2, B-3, B-5, B-6, B-7, B-9, ad B-12. These water-soluble vitamins have a list of functions, including maintaining the growth of red blood cells, brain function, digestion, eye-sight, energy levels, and more. Legumes, leafy greens, eggs, seeds, and dairy products are the best food sources for vitamin B-complex.
- Vitamin C has several roles to play, and two of its primary functions are to create neurotransmitters and collagen. So it is essential for good skin and proper brain function. Oranges, kiwi, bell pepper, cabbage, tomatoes, and strawberries are the best sources of Vitamin C.
Trace minerals are an essential category of micronutrients that are vital for maintaining good health. They are needed in minimal amounts, most of which can be obtained through food sources or dietary supplements.
Some of the many body functions they help you with include faster metabolism, energy production, cell growth and development, muscle and nerve functioning, hormone regulation, and immunity. Here is a list of trace minerals.
- Chromium: Vital for fat and sugar metabolism, chromium enhances insulin sensitivity and promotes the metabolism of lipids, proteins, and carbohydrates. Grapes juice, turkey breast, and green beans are the best sources of chromium.
- Copper is a basic need for the proper function of the nervous system. It also promotes normal brain functioning and the formation of connective tissues. Cashews, crabs, and liver are the best source of copper.
- Fluoride is an essential content for teeth as it reduces cavities. It is also helpful for bone growth. The best fluoride source is black tea, coffee, raisins, and oatmeal.
