Quick Take 1: Vegans and vegetarians can get B12 from plant sources, but have to consume a lot of these foods daily, including organically grown cress, shitake mushrooms, nori seaweed, and fermented vegetables
Its not very common, but what happens if you inject B12 wrong
Real-life reviews show a mix of experiences
Oral B12 is usually taken daily at 1,000 to 2,000 mcg
Molecular pathways documented in preclinical research include: (1) activation of nitric oxide (NO) synthesis via L-arginine/eNOS pathway, (2) transcriptional upregulation of VEGF-A and FGF-2 favouring angiogenesis, (3) modulation of the Egr-1 early transcription factor involved in fibroblast proliferation, (4) interaction with 5-HT2A and dopaminergic receptors in some behavioural models, (5) stabilisation of endothelial function via eNOS modulation and reduction of oxidative stress (8-OH-dG, MDA)
When used responsibly by qualified professionals, trigger point injections can complement such strategies and give patients the ability to actually participate in physical therapy
