DHEA 50 mg By i-Health Overview & Drug Interactions

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.

Dehydroepiandrosterone (DHEA) is a natural (i.e., endogenous) hormone produced by the adrenal gland and is among the most abundant steroid hormones in the human body. It is a precursor to the hormones testosterone and estrogen, and it is thought to have various effects on the body. DHEA levels naturally decline with age. It is a popular over the counter supplement that is purported to have a variety of health benefits, including increasing muscle mass, improving cognitive function, improving mood and reducing the risk of heart disease and diabetes. The scientific evidence supporting the use of DHEA for these purposes is limited and mixed. Additionally, it could potentially interact with several different medications so if you are considering taking DHEA supplements, it is important to speak with a healthcare professional. DHEA should not be confused with other supplements containing the letters 'DHEA'. 7-alpha-hydroxy-DHEA, 7-beta-hydroxy-DHEA, and 7-keto-DHEA, all contain DHEA as the parent compound with additional structures attached.
