Collagen Peptides By NutraA2Z 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.

Collagen peptides are a form of collagen, a protein that is found in the connective tissue of animals. Collagen is a major component of the skin, tendons, ligaments, and bones, and it plays a key role in maintaining the strength and integrity of these tissues. Collagen peptides are made by breaking down collagen into smaller pieces, or peptides, which can be more easily absorbed by the body. It is sold as a dietary supplement and often marketed as being able to improve skin health, reduce inflammation, and enhance joint function. There is some evidence to suggest that collagen peptides may have certain health benefits when taken as a supplement. For example, studies have shown that collagen peptides can improve skin elasticity and reduce the appearance of wrinkles, as well as reduce joint pain and improve mobility in people with osteoarthritis. However, more research is needed to fully understand the potential benefits and risks of taking collagen peptides as a supplement. As a dietary protein, it is thought to be relatively safe to combine with most drugs.
