You may have heard the word peptides everywhere lately. They are being discussed in relation to metabolism, tissue repair, muscle development, sleep, cognitive performance, immune function, healthy aging, sexual wellness, and more. But what exactly are they—and where do they fit within the Bedrock approach? What are peptides? Peptides are short chains of amino acids. You can think of amino acids as individual letters and peptides as short words created from those letters. Proteins are the much longer sentences and paragraphs. Your body naturally produces thousands of peptides. Many act as biological messengers, helping cells communicate with one another and coordinating processes such as: • Hormone signaling • Immune activity • Inflammatory responses • Tissue repair • Metabolism • Sleep and circadian rhythms • Cognitive function • Growth and recovery In other words, peptides do not simply “make” the body perform a particular function. They often work by delivering a message. That distinction is important because it aligns with something we have always taught at Bedrock: The body already knows what to do. Our job is to identify what may be interfering with that communication and provide the body with the raw materials, environment, and appropriate signals it needs to do its work. What does “buccal” mean? Buccal refers to the inner lining of the cheek. With buccal delivery, a dissolving strip is placed inside the mouth so its ingredients can potentially pass through the oral mucosa rather than first traveling through the entire digestive tract. This is different from simply swallowing a capsule. Peptides can be difficult to deliver orally because digestive enzymes may break them apart and their larger molecular structures can limit absorption. The oral mucosa provides another possible route, with access to a blood-rich tissue surface and partial avoidance of gastrointestinal degradation and first-pass metabolism. However, absorption can still vary substantially depending on the specific peptide, its molecular properties, the formulation, the dose, the delivery technology, and the individual using it.

For years, researchers have observed something fascinating. People who use a traditional Finnish sauna several times each week tend to experience lower rates of: - Hypertension - Cardiovascular disease - Fatal heart attacks - Dementia - Alzheimer’s disease - Pneumonia - All-cause mortality The question has always been… Why? Is it simply relaxation? Better circulation? Lower stress? Or is something much deeper happening inside the body? A new study published in Temperature offers another important piece of that puzzle. The Study Researchers recruited 51 middle-aged adults, all with at least one cardiovascular risk factor. Participants completed a single 30-minute Finnish sauna session at 73°C (163°F). The researchers measured: - Body temperature - White blood cells - Plasma volume - 37 different inflammatory cytokines Measurements were taken: - Before the sauna - Immediately afterward - Thirty minutes later The results were surprising. Your Immune Cells Respond Immediately Body temperature increased from 36.4°C to 38.4°C (97.5°F to 101.1°F). Importantly, plasma volume did not change significantly. That means the increase in immune cells wasn’t simply due to dehydration concentrating the blood. Instead… The immune system actually mobilized. Researchers found significant increases in: - White blood cells - Neutrophils - Lymphocytes - Monocytes - Eosinophils - Basophils Neutrophils and lymphocytes returned to normal within about 30 minutes. However, monocytes, eosinophils, and basophils remained elevated even after the recovery period. Think of it like this: The heat appears to temporarily “deploy” immune cells into circulation—almost like calling additional responders into active duty. What About Inflammation? This is where things became even more interesting. Researchers measured 37 inflammatory cytokines—chemical messengers that help coordinate immune activity. You might expect those markers to rise dramatically.
