There’s a lot of buzz about peptides – they’re strings of amino acids, the building blocks of proteins. They power a huge range of essential biological functions in the body, from hormone regulation to triggering neurotransmitters. And because of their multifaceted benefits, they’re being added to everything from dietary supplements and protein powders to high-end beauty and skin products.
Peptides are created by the body and also found in foods like eggs, milk, and fish. They work as hormones, neurotransmitters, and growth factors, helping with cell communication, metabolism, and the immune system. They also help repair and regenerate tissues, and they’re the secret behind why collagen-rich skincare is so popular.
They stimulate the production of keratin and other new cells, boosting collagen and elastin levels, which in turn reduces wrinkles and improves firmness, smoothness, and evenness of tone. They can also ease inflammation, promote wound healing, and even kill bacteria that cause acne. And, because of their small size, they can penetrate deep into the skin to work where the damage is – softening laughter lines and wrinkles, plumping the lips, evening out tone, and boosting collagen levels.
Because of their unique biological properties, peptides have been attracting interest in the pharmaceutical industry. They’re easy to produce and can be modified to target specific receptors in a tumor cell, making them an ideal drug candidate. To date, there are three main methods for producing peptides: derivation from natural proteins, chemical synthesis, and reasonable engineering based on structure. However, due to their short half-life in vivo, peptide drugs typically have poor membrane permeation and low stability, which limits their clinical use.
But there’s a way to bypass these drawbacks: using phage-display technology to create modified peptide analogues. Phage-display technology uses phages to screen for peptide sequences that can bind to a given receptor in a targeted cell. This approach can achieve a rapid, cost-effective, and high-quality screening process for peptide drugs.
Choosing the right peptides can improve athletic performance, boost libido, aid in weight loss, treat osteoarthritis and other musculoskeletal issues, prevent age-related bone density loss, and much more. However, it’s important to choose the right type of peptide and combine it with other ingredients to get the best results.
For example, some peptides are neurotransmitter inhibitors that temporarily block chemicals that cause muscle strain, which can reduce the appearance of wrinkles. Other peptides encourage the growth of new cells, which can make the skin appear more vibrant and youthful. And some peptides can even boost the production of hyaluronic acid, which in turn reduces fine lines and wrinkles.
But there’s no single benefit that can be attributed to peptide treatment. Your specific health needs will determine which ones are the right fit for you, and that’s why it’s important to choose a peptide treatment that works with your body’s natural processes.
