Healthy Skin & Hair plus Nails By Irwin Naturals Overview & Drug Interactions

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.

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.

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.

Manganese is an essential trace mineral that plays a vital role in various physiological processes within the human body. It is required for proper brain function, bone formation, enzyme activation, and wound healing. Manganese also contributes to metabolism, antioxidant defense, and the formation of connective tissues.

Flaxseed, also known as linseed, is a type of seed that is rich in nutrients and other compounds. It is a good source of fiber, protein, and omega-3 fatty acids, as well as a variety of vitamins and minerals. Flaxseed is often ground and used as a supplement in the form of flaxseed meal or oil. Flaxseed has a number of potential health benefits. It is high in fiber, which can help improve digestion and lower cholesterol levels. The omega-3 fatty acids found in flaxseed are believed to have anti-inflammatory properties and may help reduce the risk of heart disease and stroke. Flaxseed is also a rich source of lignans, plant compounds that have been shown to have estrogen-like effects. Both flaxseed and flaxseed oil are popular dietary supplements and share many of the same purported health benefits. However, one of the main differences between the two is the amount of fiber they contain. Flaxseed is a good source of both soluble and insoluble fiber, while flaxseed oil does not contain any fiber. This means that flaxseed can help improve digestion and lower cholesterol levels, while flaxseed oil does not have these effects.

Gotu kola (Centella asiatica) is a perennial herb and a member of the carrot family. It has small, white or pink flowers, fan-shaped leaves and is often found growing in damp, marshy areas. The leaves and stems of the gotu kola plant are used in herbal medicine as a natural remedy for a variety of health conditions, such as gastrointestinal disorders, amenorrhea, eye conditions, heat stroke, leprosy, liver health, lymphatic obstruction, and infections. It is not to be confused with similarly named plant, Cola Nut, or bacopa.

Horsetail, also known as equisetum, is a type of perennial herb that belongs to the Equisetaceae family. It is native to much of the Northern Hemisphere and has distinctive, jointed stems that resemble the tail of a horse, hence common name. Some species of horsetail are used medicinally and have been traditionally used to treat a range of ailments, including kidney and bladder problems, wounds, and hair loss. It is most commonly used in traditional medicine as an oral diuretic (i.e., water pill) for the treatment of edema. It is important to note that some species of horsetail (e.g., Equisetum palustre) may be toxic and should not be consumed. Additionally, some types of horsetail contain thiaminase, which can cause thiamine deficiency with prolonged use.
