Compare mechanism, clinical dose, safety profile, and products containing each ingredient.
Overview
Omega-3 (EPA/DHA) is usually chosen for Most adults, especially those not eating fatty fish, while Vitamin B12 is often selected for Vegans, elderly, those with absorption issues.
Essential fatty acids for brain health, heart health, reducing inflammation.
Clinical dose: 1000-3000 mg
Safety: Possible side effects include mild digestive discomfort, nausea, or headache, typically dose-related and more common when intake is escalated quickly.
Essential for energy metabolism, nerve function, red blood cell formation.
Clinical dose: 500-2500 mcg
Safety: Possible side effects include mild digestive discomfort, nausea, or headache, typically dose-related and more common when intake is escalated quickly.
Omega-3 (EPA/DHA)
Marketing claims: "Heart healthy," "Brain food." Reality: Strong evidence for cardiovascular benefits in at-risk populations. Brain/cognitive claims are weaker in healthy adults — effects mainly seen in deficient individuals or those with existing conditions. "1000mg fish oil" often means only 300mg actual EPA+DHA.
Vitamin B12
Marketing claims: "Energy booster," "Mood support." Reality: B12 only provides energy if you are deficient. For those with adequate levels, extra B12 is simply excreted — expensive urine. Blood tests can confirm deficiency before supplementing. High doses (5000mcg+) offer no advantage over 500-1000mcg.
