A 2017 study found that B12 supports healthy sperm by increasing sperm count and reducing damage to DNA
Urinary or plasma methylmalonic acid (MMA), a substance produced in the body thats dependent on B12, is also helpful for detecting early stages of B12 deficiency
You can have vitamin B12 deficiency anemia if you don't get enough vitamin B12 in your diet from foods like milk, eggs, and meat, or if your body can't absorb B12 because of a health problem
Draw air into the syringe equal to your dose, inject this air into the vial, then draw out the appropriate amount of peptide solution

Thus were the conclusions made in a 2015 paper published in Cell Metabolism , in which the authors noted that MOTS-c has physiological similarities to the first-line diabetes drug metformin with regard to managing glucose utilization, metabolism, and body weight.18 Reduced body fat Considering the effects that MOTS-c has on insulin response and glucose uptake two factors associated with weight gain the authors of the 2015 paper referenced above also examined the peptides potential for preventing obesity.19 Specifically, in a group of mice fed a high-fat diet, MOTS-c appeared to prevent obesity onset.18 Other studies have corroborated these results by finding that higher plasma MOTS-c levels are negatively correlated with obesity.20 Improved physical performance Recall that endogenous MOTS-c can be activated by exercise, allowing your skeletal muscles to use glucose for energy to meet their high energy demand
