“Omega-3 fatty acids may help reduce bone loss, a 2010 study showed. When astronauts – who often experience bone loss after periods of weightlessness – consumed omega-3s during short-duration space missions, they experienced less bone loss.”

“This 2022 review provides an overview of the science surrounding osteocalcin – a hormone that participates in a wide range of physiological processes throughout the body, including glucose homeostasis, exercise capacity, brain development, cognition, and male fertility, highlighting the many ways in which bones influence health.”

“It also participates in many biological processes driving pregnancy outcomes, maintaining bone mineral density and muscle mass in older adults, improving neurological function, and aiding the immune system to fight cancer.”

“Protein exerts variable effects (both good and bad) on a person's calcium balance, depending on their dietary calcium intake. For example, dietary protein promotes the production of insulin-like growth factor-1, a protein involved in bone formation.”

“The elderly women with low bone-density supplemented with L. reuteri 6475 (1x1010 CFU/day) or placebo for 12 months. There was a 50% reduction in total bone density in the distal tibia. The two groups were similar regarding all anthropometric and lifestyle factors.”

“This does not establish an upper limit for muscle growth, strength, power, bone health, metabolic health, or physical function, because the study examined mortality rather than those outcomes. People reporting substantial amounts of both forms of exercise generally had the lowest mortality.”

“Additionally, the mice that were fed nicotinamide mononucleotide had improved skeletal muscle mitochondrial function, increased energy expenditure, increased bone density, and decreased insulin resistance in a dose-dependent manner.”

“However, the investigators noted a few generalizations regarding the outcomes. The participants' energy expenditure, core body temperature, fasting insulin levels, bone mass, muscle size and strength, and markers of oxidative stress and DNA damage decreased.”

“Aging compromises muscle strength and bone density, altering the signaling pathways that coordinate their function. These pathways involve myokines—hormone-like proteins released by muscle during exercise that help regulate metabolism, enhance muscle performance, and support bone formation.”

“In rheumatoid arthritis, upregulation of TNF-alpha, a proinflammatory cell-signaling protein, induces autophagy, promoting the differentiation of osteoclasts, a type of bone cell that breaks down mineralized tissue in the joint, destroying the joint architecture.”
