As a naturally occurring protein hormone, MOTS-c is primarily activated by exercise or some type of stress, whereupon it translocates to the cells nucleus and mediates mitochondrial-nuclear communication.11 This crosstalk is crucial for coordinating the many mitochondrial functions and maintaining homeostasis.12 MOTS-c also activates the AMP-activated protein kinase (AMPK) pathway, a key regulator of cellular metabolism and homeostasis that helps produce energy by stimulating glucose uptake and fat oxidation.13 Much of this activity takes place in the skeletal muscles, which are rich in mitochondria because of their high energy demand.14 Over time, MOTS-c loses influence because its concentration declines with age.11 Consequently, people can become increasingly susceptible to some of the health conditions weve mentioned, many of which you may have noticed are largely age-correlated

The bone marrow Because haptocorrin is made by white blood cells, conditions in which the marrow overproduces those cells raise the total B12
B12 supplements or B12 shots
Conversely, some studies show that a deficiency in vitamin B12 may cause appetite loss, potentially leading to weight loss if left untreated ( If youre low or deficient in B12, your healthcare provider will likely recommend oral vitamin B12 supplements or injections to increase your blood levels ( summary Low levels of vitamin B12 can cause megaloblastic anemia, which is characterized by shortness of breath, headaches, and fatigue
