Best for: People sensitive to methyl-B12 Those with histamine intolerance or mast cell issues Overmethylators or those with anxiety from methylated vitamins Detoxification support (binds to toxins like cyanide and nitric oxide) Balanced, gentle B12 support Advantages: Body controls conversion rate (less likely to cause overmethylation) Supports detoxification pathways Well-tolerated by most people Longer-lasting in the body than methyl-B12 Potential downsides: Requires conversion (may be less efficient with severe MTHFR mutations) Slightly less direct methylation support than methyl-B12 Can be harder to find in supplements Typical dosage: 1000-5000mcg daily 3
