Collagen Peptides Overview

Collagen Peptides 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.

Levothyroxine Overview

  • Levothyroxine is used to treat hypothyroidism (condition where the thyroid gland does not produce enough thyroid hormone). It is also used with surgery and radioactive iodine therapy to treat thyroid cancer. Levothyroxine is in a class of medications called hormones. It works by replacing thyroid hormone that is normally produced by the body.

  • Without thyroid hormone, your body cannot function properly, which may result in poor growth, slow speech, lack of energy, excessive tiredness, constipation, weight gain, hair loss, dry, thick skin, increased sensitivity to cold, joint and muscle pain, heavy or irregular menstrual periods, and depression. When taken correctly, levothyroxine reverses these symptoms.
