Whey Protein Isolate Unflavored By California Gold Nutrition SPORT Overview & Drug Interactions

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).

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.

Whey protein is a type of protein derived from cow's milk. Specifically, whey comes from the cheesemaking process. Enzymes are added to milk, which separates the milk into cheese curds and liquid whey. Whey is a complete protein, meaning that it contains all nine essential amino acids that the body needs but cannot produce on its own. Whey protein is often used as a supplement to help build and repair muscle tissue, and it is popular among athletes and bodybuilders. There are three main types of whey protein: concentrate, isolate, and hydrolysate. The concentrate contains a higher amount of lactose (milk sugar) and fat, while isolate is a purer form of protein that contains less lactose and fat. Hydrolysate is a predigested form of whey protein that is easier for the body to absorb. Whey protein is often consumed in the form of powders, shakes, and bars, and it can be mixed with water, milk, or other beverages. Drug interactions with whey protein typically result due to the calcium content of whey, which can decrease absorption of some drugs, including many classes of antibiotics.
