The coenzyme forms, methylcobalamin and adenosylcobalamin, have been heavily marketed but poorly studied, with typical recommendations of 1,000 µg/day based more on caution than evidence. A 2026 randomized trial (MATCOBIND)… ## [Folic Acid and Vitamin B12: How Much is Safe?](https://veganhealth.org/folic-acid-and-vitamin-b12-how-much-is-safe/) _2026-05-24 · JackNorrisRD · Vegan Health_ by Jack Norris, Registered Dietitian For some time, there have been concerns that supplementing with either B12 or folic acid (the synthetic version of folate) may raise blood levels high enough to increase cancer risk. These concerns are somewhat related because I recommend multivitamins as an option for obtaining vitamin B12 for vegans, and most \[…\] The post Folic Acid and Vitamin B12: How Much… ## [(untitled)](https://norgenbiotek.com/blog/purified-exosomes-regenerative-medicine) _2026-04-15 · NORBLOG_ Exosomes are nano-sized extracellular vesicles (about 30-200 nm) that bud from endosomal membranes and are released by almost every cell type. 6 Because they are enclosed by a lipid bilayer and carry proteins, lipids and various RNAs, exosomes act as messengers between cells and can be harvested from blood, urine, milk or cultured cells. In regenerative medicine, purified exosomes have emerged as… ## [Calcium and Colorectal Cancer](https://veganhealth.org/calcium-and-colorectal-cancer-post/) _2026-04-08 · JackNorrisRD · Vegan Health_ by Jack Norris, RD In light of a recent meta-analysis in which vegans had a higher risk of rectal cancer, we reinforced our recommendation that vegans should aim to meet the RDA for calcium; see Cancer Meta-Analysis (Another One!).
