This cod liver oil offers very low concentrations of EPA and DHA, making it largely insufficient for significant heart, brain, or vision support. While it provides some Vitamin A and D, its efficacy for stated omega-3 related goals is minimal.

insightsAnalysis

The 21st Century Norwegian Cod Liver Oil is a basic supplement that provides a very low dosage of the key omega-3 fatty acids, EPA and DHA. Each softgel contains a mere 28mg of EPA and 24mg of DHA, totaling only 52mg. For adults seeking meaningful cardiovascular, cognitive, or visual support, this amount falls significantly short of expert recommendations, which typically suggest at least 250-500mg daily for general health, and often higher for specific therapeutic effects.

While the product does supply Vitamin A (375mcg) and Vitamin D3 (3.4mcg), which contribute to vision and overall health respectively, the core benefit for omega-3-related goals is severely limited. Consumers looking for potent omega-3 support would likely find this product ineffective, needing to consume a large number of softgels to reach beneficial dosages, which could also lead to excessive Vitamin A intake. Furthermore, the brand is generally known for more economical options rather than highly concentrated or premium formulations.

thumb_upPros
  • Convenient softgel form for easy consumption.
  • Provides naturally occurring Vitamins A and D from cod liver oil.
  • Accessible option for basic supplementation.
thumb_downCons
  • Extremely low dosage of active EPA and DHA per serving, limiting efficacy.
  • Unlikely to provide significant benefits for cognitive, heart, or vision health at recommended serving size.
  • May require consuming many softgels to reach effective omega-3 levels, risking excessive Vitamin A intake.
warningWarnings
  • Individuals taking other Vitamin A supplements should monitor total intake to avoid exceeding safe limits, especially if increasing servings to obtain more omega-3s.
  • Those with fish allergies should avoid this product.

Categories

DHA (Docosahexaenoic Acid) 40
The DHA content of 24mg per serving is exceptionally low and largely inadequate to deliver significant benefits associated with this crucial fatty acid, especially for brain and eye health.
storefront View products
EPA (Eicosapentaenoic Acid) 40
Offering only 28mg of EPA per serving, this product provides an insufficient dose for the recognized anti-inflammatory and cardiovascular benefits typically associated with EPA supplementation.

Goals

flag Vision Support 50
While it contains Vitamin A (375mcg), which is beneficial for vision, the extremely low DHA content (24mg), a critical component of the retina, limits its comprehensive vision support efficacy.
flag Heart Health 40
With only 52mg of combined EPA and DHA, this product provides a negligible amount for meaningful heart health support, falling far below evidence-based recommendations for cardiovascular benefits.
flag Cognitive Support 40
The very low dosages of EPA and DHA (28mg and 24mg respectively) are insufficient to significantly support cognitive function, mental focus, or overall brain health, which typically require substantially higher daily intake.
