Safety Profile

Overall safety rating: Generally Safe

Potential Side Effects

  • Beeturia — harmless red or pink discoloration of urine (affects ~10-14% of people)
  • Red discoloration of stools (harmless)
  • Mild GI discomfort at high doses
  • May lower blood pressure too much in hypotensive individuals
  • Potential kidney stone risk in those with oxalate sensitivity (beets are high in oxalates)

Drug & Supplement Interactions

  • Blood pressure medications — additive hypotensive effect; monitor BP closely
  • PDE5 inhibitors (Viagra, Cialis) — both increase nitric oxide; combined use may cause excessive vasodilation
  • Blood thinners — beet root has mild antiplatelet properties

Maximum Dose

Do not exceed: No established upper limit for dietary nitrate from beet root; doses up to 800mg nitrate studied safely
