What Do B12 Injections Do to Help with Weight Loss?

Aid in Weight Loss

Although B12 injections themselves do not cause weight loss, they support weight management by reinforcing metabolic function.

Vitamin B12 is very instrumental in bone health through the support of appropriate functioning osteoblasts responsible for growth and repair in bones. Low levels of B12 have, therefore, been associated with increased risks of osteoporosis in older adults since poor levels of B12 could minimize bone mineral density. This, over time, may weaken bones and make them more susceptible to fractures. By making the body have adequate B12, the injections enhance the bones’ strength and density to decrease the tendency of fractures, among other complications that relate to the bone. This is especially helpful for individuals at risk of osteoporosis, such as post-menopausal women and the elderly. It helps preserve bone strength and maintain mobility as they age.

The medications of B12 help in sleep regulation, in particular, due to the effects the medications have on melatonin production, which generally characterizes or controls sleep. Melatonin levels rise in the evening, preparing the body for rest, and decrease in the morning to help wakefulness. Low B12 can disrupt melatonin production and can contribute to insomnia or other sleep-wake cycle problems. With injections, the levels of B12 get improved, so that the correct balance of melatonin can occur within the body and help with regulating the circadian rhythm. This would lead to more consistent, restful sleep without waking up tired or experiencing daytime sleepiness.
