Vitamin D is a fat-soluble vitamin that plays a crucial role in several bodily processes. It helps the body absorb calcium and phosphorus, which are necessary for healthy bones and teeth. It is also important for immune system function and may help to protect against certain diseases. Vitamin D is found in a variety of foods, including fatty fish, egg yolks, and fortified foods such as milk and cereal. It is also produced by the body when the skin is exposed to sunlight. Vitamin D supplements are available in a variety of forms, including tablets, capsules, and liquids. The recommended daily intake of vitamin D varies depending on age, sex, and other factors, and it is important to follow the dosage recommendations provided by a healthcare professional. There are several different forms of vitamin D available, with the two most popular being ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3).

Vitamin E is a fat-soluble vitamin found naturally in a variety of foods, including vegetable oils, nuts, seeds, and leafy green vegetables. Vitamin E is also available as a dietary supplement and is often added to skincare products. Vitamin E has many roles in the body, including protecting cells from oxidative stress and supporting immune function.

Niacin, also known as vitamin B3, is a water-soluble vitamin found in a variety of foods, including meat, poultry, fish, and fortified grains. It plays a variety of roles in the body, including in the metabolism of carbohydrates, fats, and proteins. It is also necessary for the production of energy in the body and in the synthesis of different hormones. Niacin deficiency is rare in developed countries, however, supplementation has been shown to have several positive benefits. For example, it can reduce the risk of diabetic neuropathy (i.e., nerve pain) and has been shown effective for treating some types of high cholesterol (extended-release niacin is used as a prescription drug in the United States for this purpose). There is a multitude of niacin forms available as dietary supplements, including NADH, niacinamide, and nicotinamide riboside, all with different properties.

Folate and folic acid are forms of vitamin B9, essential for health. Folate occurs naturally in foods like leafy vegetables, legumes, and fruits, while folic acid is the synthetic form used in supplements and fortified foods. Since 1998, the US has fortified cereals, baking flour, pasta, and bakery items with folic acid to prevent deficiencies. Naturally occurring folate, or pteroylpolyglutamate, has lower bioavailability (40% to 50%) compared to nearly 100% for synthetic folic acid. Foods rich in folate include asparagus, mushrooms, yeast, legumes, spinach, broccoli, lettuce, bananas, melons, oranges, tomatoes, lemons, and animal products like beef liver and kidney. Some supplements contain L-5-methyltetrahydrofolate (L-5-MTHF), a reduced folate form. L-5-MTHF, dependent on vitamin B12 for metabolism, is absorbed faster and more effectively than folic acid, especially in individuals with specific MTHFR genotypes. Studies show that women taking L-5-MTHF had slightly higher red blood cell folate concentrations compared to those taking folic acid, although long-term use results in similar blood levels and effectiveness for preventing neural tube defects.

Vitamin B12, also known as cobalamin, is a water-soluble vitamin crucial for several bodily functions. It plays a pivotal role in the formation of red blood cells, aiding in the prevention of anemia. Vitamin B12 is essential for maintaining a healthy nervous system and proper brain function, as it is involved in the synthesis of myelin, the protective sheath around nerve fibers. This vitamin is primarily found in animal-based foods such as meat, fish, dairy products, and eggs, making it important for vegetarians and vegans to consider supplementation. A deficiency in vitamin B12 can lead to neurological issues, fatigue, and cognitive impairment.

Biotin, also known as vitamin H or vitamin B7, is a water-soluble vitamin that plays a role in various metabolic processes in the body. It is necessary for the growth and maintenance of healthy skin, hair, and nails, and is also involved in the metabolism of carbohydrates, fats, and amino acids. Biotin is considered to be generally safe when consumed in the recommended daily amounts but it is important to note that consuming large amounts of biotin-containing supplements or products can cause falsely high or falsely low test results for certain laboratory tests, such as those for thyroid function, hormone levels, and certain biomarkers for certain diseases.

Iodine is a mineral that is crucial for our body's ability to produce thyroid hormone, which helps control our growth, metabolism, and energy levels. A lack of iodine in the diet is a common problem around the world and can lead to intellectual development issues. Adding iodine to salt (i.e., iodized salt) has helped reduce this problem. Iodine is commonly utilized as a dietary supplement, both in multivitamin preparations and as a standalone ingredient as it is purported to have overall health and wellness benefits, not just in those who are deficient. One such standalone iodine product is 'Iodoral'. Studies have shown iodine supplementation may help improve cognitive function and boost energy levels but more research is needed. It is recommended that you should be under medical supervision if you plan on taking iodine as there may be a risk of certain side effects with high dosages.

Magnesium is a mineral that is essential for the proper functioning of the body. It plays a role in many important physiological processes, including the contraction and relaxation of muscles, the transmission of nerve impulses, and the regulation of blood pressure. Magnesium is found in a variety of foods, including leafy green vegetables, nuts, and grains, and it is also available as a dietary supplement. There are several different forms of magnesium that are available as supplements, all of which can be used to prevent deficiency. Additionally, magnesium is purported to have several different health benefits, such as improving sleep, reducing muscle cramps, reducing anxiety, and preventing or treating migraines. Although magnesium is essential for health, magnesium-containing foods and supplements can interact with some prescription medications if used at the same time.

Zinc is a mineral that is essential for the proper functioning of the human body. It is involved in many important physiological processes, including immune system function, wound healing, taste, and smell. Zinc is found in a variety of foods, including meat, seafood, and whole grains, and it is also available as a dietary supplement. Zinc supplements may be used to treat or prevent zinc deficiency, which can occur due to certain medical conditions, such as gastrointestinal disorders, alcohol abuse, and certain medications. Zinc supplements may also be used for other purposes, such as to boost the immune system, improve acne, and reduce the severity and duration of colds. There are several different forms of zinc supplements available, including zinc gluconate, zinc acetate, and zinc sulfate. The most common form of zinc supplements is zinc gluconate, which is well absorbed and is less likely to cause stomach-related side effects than other forms of zinc.

Selenium is an essential trace element that plays a crucial role in various physiological functions in the human body. It is often included in dietary supplements due to its antioxidant properties and its contribution to maintaining a healthy immune system. Selenium is important for thyroid function and may also have a role in protecting against certain chronic diseases. However, it's essential to note that excessive selenium intake can be harmful, so it's crucial to adhere to recommended daily allowances and consult with a healthcare professional before taking selenium supplements.

Chromium is a trace mineral that is found in small amounts in the human body. It is believed to play a role in the metabolism of carbohydrates, fats, and proteins. It is used as a dietary supplement for its purported ability to help with weight loss and blood sugar control. There is some evidence to suggest that chromium supplements may help to improve blood sugar control in people with type 2 diabetes, although the results of studies on this topic have been mixed. Some studies have found that chromium supplements can improve insulin sensitivity and reduce blood sugar levels in those with poorly controlled diabetes, while others have found no significant effects.

Coenzyme Q10, also known as CoQ10, is a naturally occurring substance that is found in every cell of the body and plays an essential role in energy production within the mitochondria, which are the powerhouse of the cells. CoQ10 also acts as an antioxidant, protecting cells from damage caused by harmful free radicals. While CoQ10 is endogenous, meaning our body can produce it on its own, levels can decrease with age, with certain medications (e.g., statins) or due to certain medical conditions. In such cases, supplementation with CoQ10 may be beneficial. Additionally, CoQ10 supplements have been studied for a variety of health benefits, including improving heart health, reducing inflammation, and potentially even aiding in the treatment of neurological disorders such as Parkinson's disease. However, it's important to note that while some studies have shown potential benefits, the research on CoQ10 supplementation is still ongoing, and more studies are needed to fully understand its effects on the body.

Lycopene is a natural red pigment and powerful antioxidant found in various fruits and vegetables, notably in tomatoes, watermelon, guava, and grapefruit. It belongs to the carotenoid family and is responsible for the vibrant red color in these foods. Studies suggest that lycopene may have health benefits, including reducing the risk of chronic diseases, such as heart disease and certain types of cancer, due to its antioxidant properties. It is best absorbed by the body when consumed with fats or oils.

Zeaxanthin is a type of carotenoid, a natural pigment found in plants and fruits, particularly in leafy greens and colorful vegetables. It is known for its antioxidant properties and its role in supporting eye health by protecting against harmful light-induced damage. Zeaxanthin is often used in dietary supplements targeted at promoting optimal vision and reducing the risk of age-related macular degeneration.
