The B Vitamin You're Probably Overdosing On #peptides #health

About this video

In this short clip, Seeds and a colleague argue that vitamin B12 is among the most over-consumed vitamins because many people assume more is automatically better. Seeds claims excess B12 produces its own problems, describing symptoms such as increased nerve excitability, neuropathy-type complaints, brain fog, and reduced executive function — which he notes can paradoxically resemble the symptoms of deficiency. He also argues that genetic test results related to B-vitamin metabolism are frequently misinterpreted, leading people to panic and self-supplement aggressively without proper context. The takeaway he pushes is educational: labs and genetics need interpretation, and bringing levels back into a normal range, rather than maximizing them, is the goal.

Key takeaways

• Seeds argues B12 excess can mimic B12 deficiency, making self-diagnosis by symptoms alone unreliable
• He claims widespread over-supplementation is driven partly by misread genetic reports
• Normalizing a level is presented as the goal, not pushing it as high as possible
• He frames supplement decisions as requiring lab context rather than fear-based reactions
