Summary

B vitamins are a group of eight essential water-soluble nutrients that act as coenzymes in numerous critical metabolic pathways, including energy production (ATP synthesis), DNA synthesis and repair, and methylation. Maintaining adequate levels is foundational for cellular health, preventing deficiencies that can impair neurological function, increase homocysteine levels (a risk factor for cardiovascular disease), and compromise overall vitality.

Purpose

Supports cellular energy, DNA integrity, and methylation pathways.

Card Summary

A group of essential coenzymes vital for cellular energy production, DNA repair, and methylation, crucial for foundational metabolic health.

Impact

Score:
6.5
Justification:
Essential for foundational metabolic health; prevents deficiencies that accelerate aging processes.

Evidence

Grade:
A
Score:
8.5
Justification:
Vast body of evidence confirms their essential role in human metabolic health.

Safety

Score:
3
Justification:
Generally safe as water-soluble, but high doses of B6/B3 can cause side effects.

Flags

  • High doses of Vitamin B6 (pyridoxine) can lead to peripheral neuropathy (nerve damage).
  • High-dose niacin (B3) can cause skin flushing, itching, and potential liver stress.
  • Folate (B9) supplementation can mask a Vitamin B12 deficiency, which can lead to irreversible neurological damage if unaddressed.
  • Some B vitamins may interact with medications like methotrexate and certain anti-epileptic drugs.

Verdict

Essential for foundational metabolic health; supplement to prevent or correct deficiencies.
