The process of arterial stiffening through atherosclerosis occurs when arteries become more prone to blockages.Scientific research shows that taking excessive doses of vitamin D creates conditions where calcium forms deposits in arteries, instead of bones leading to future heart disease development.Research: What Does the Science SayObservational studies demonstrate that very low vitamin D levels are connected with higher heart risks, even though research on vitamin D supplements and injections for heart disease prevention remains inconclusive.Studies of high vitamin D dosages in animals sometimes show arterial calcification, but the results do not consistently apply to human subjects.Research demonstrates that vitamin D toxicity from excessive doses or prolonged use, results in elevated blood calcium levels which can cause arterial calcification and potentially lead to blocked arteries.Research indicates that Vitamin D deficiency poses risks to the heart, but high or excessive intake in people who do not require it, does not offer clear cardiovascular benefits and could potentially cause harm.Are Vitamin D Shots Safe for Your ArteriesThe majority of people experience no harm from receiving a single shot or undergoing short-term medical treatment under doctor supervision
Vein ligation and stripping is reserved for chronic venous insufficiency, to treat symptomatic disease involving reflux in the saphenous vein system (Weiss 2016)
Some plant-based milks, cereals, and nutritional yeast are fortified with B12, which can certainly help
These injections offer real benefits for specific situations, but they're not a one-size-fits-all solution
Most apparent tolerance situations resolve with targeted intervention
If none of those apply and you eat a varied diet that includes animal products, your B12 status is less likely to be a concern during treatment
