Thats because utilization of vitamin B12 (especially from supplements) depends on levels of other metabolic cofactors and acids
The British Society for Haematology emphasises that treatment should not be delayed whilst awaiting confirmatory test results if clinical suspicion of B12 deficiency is high, particularly when neurological symptoms are present
INTRODUCTION Obesity is a major public health problem around the world that is linked to severe comorbid disease conditions, physical impairment, high mortality rates, and compromised quality of life.[14] Obesity is characterized by the buildup of excessive body fat and extreme dysregulation in whole-body energy expenditure, glucose, hormone, and lipid homeostasis that typically present as adverse metabolic disorders.[4, 5] Additionally, the physiological, metabolic, and psychological changes that accompany obesity are major factors in the development of type 2 diabetes (T2D), cardiovascular disease (CVD) (e.g., coronary heart disease, dyslipidemia, hypertension),[6, 7] stroke, inflammation, non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), osteoarthritis, sleep apnea, and several obesity-linked cancers (e.g., colorectal, breast, kidney, prostate).[6, 8] Lifestyle modifications including diet and exercise may help reverse obesity and improve chronic disease biomarkers (e.g., T2D),[9] but are largely ineffective in achieving sustained weight loss and glycemic control.[10] Pharmacological treatments for obesity exist, but unfortunately most approved anti-obesity drugs have only modest efficacy and/or produce severe adverse effects (e.g., cardiovascular risks, central nervous system effects)
Overall great experience so far
