Vitamin B12
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
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.

Choline
Choline is an essential nutrient that is found in many foods, including eggs, and is important for a number of bodily functions, including liver function, brain development, and nerve function. Choline is a precursor to acetylcholine, a neurotransmitter that plays a role in memory, mood, and muscle control. Choline also helps to transport fats out of the liver, which may help to reduce the risk of liver disease. Choline supplements are available in different forms, including choline bitartrate, choline chloride, and phosphatidylcholine. Choline bitartrate is the most common form of choline supplement, but phosphatidylcholine is the form that is found naturally in foods.

Calcium
Calcium is a vital nutrient found in various foods such as dairy products, certain vegetables, and many fortified items. Over 99% of the body's calcium is stored in the bones and teeth, predominantly as hydroxyapatite. The remaining calcium circulates in the blood, extracellular fluid, muscles, and other tissues, where it is essential for processes like nerve signaling, muscle contraction, vascular activities, glandular secretion, and maintaining cell membrane and capillary permeability. It also plays critical roles in enzyme reactions, respiration, kidney function, and blood clotting, and is involved in neurotransmitter and hormone release, amino acid uptake, vitamin B12 absorption, and gastrin secretion. Calcium balance changes with age: it is positive during periods of growth, stable in adulthood, and tends to become negative in older age. Calcium loss occurs through feces, urine, sweat, and shedding skin cells. In women, reduced estrogen levels decrease calcium absorption and retention, increase bone turnover, and lead to lower bone mass. Calcium supplements come in various forms, including citrate and carbonate, which differ mainly in their calcium content and absorption rates. Calcium citrate is easily absorbed and can be taken without food, making it suitable for older adults or those with low stomach acid. In contrast, calcium carbonate, which contains a higher percentage of calcium, is best absorbed when taken with meals.

Iodine
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
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
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.

It is also known as vitamin B8 but is not considered 'essential' as it can be synthesized in the human body. Inositol is involved in a number of important physiological processes, including the metabolism of fats, the regulation of insulin, and the transmission of nerve impulses. Inositol is a popular dietary supplement and is believed to have a number of potential health benefits. It is thought to have a role in the treatment of certain mental health conditions, is believed to have a positive effect on cholesterol levels and may be helpful in the prevention or management of heart disease.

Aspartic Acid
Description:Aspartic acid, also known as aspartate, is a non-essential amino acid that plays a crucial role in various physiological processes within the body. It functions as a building block in protein synthesis and is a central component of various enzymes. Additionally, aspartic acid plays a key role in the metabolism of nitrogen. Aspartic acid has been studied for its potential benefits as a dietary supplement. Research indicates that it may aid in cognitive function and memory by increasing the levels of the neurotransmitter acetylcholine, which is critical for memory and learning. Furthermore, aspartic acid has been suggested to enhance athletic performance by increasing energy and endurance through the elevation of creatine levels. It is worth mentioning that aspartame, an artificial sweetener, contains around 40% aspartic acid. Aspartic acid exists in two forms, D-aspartic acid (D-AA) and L-aspartic acid (L-AA). The structural difference between the two forms is the arrangement of atoms in their molecular structure. D-aspartic acid is more commonly found in dietary supplements for athletics, as it has been studied for its effects on testosterone levels and muscle growth.
