Analysis

Natural Factors Ultra Strength One-per-Day RxOmega-3 delivers 1425mg of 'pharmaceutical grade Fish Oil concentrate' sourced from sardine, mackerel, and anchovy. This concentration typically implies a high percentage of EPA and DHA, although the exact amounts are not explicitly detailed for this specific product entry. The 'one-per-day' formulation is convenient for users, promoting consistent intake. Given its pharmaceutical grade status and fish sourcing, it likely undergoes rigorous purification processes to remove heavy metals and other contaminants, as is common for Natural Factors products. The price per serving of $0.41 is very attractive for a high-strength, single-dose option.

Pros
  • High concentration of fish oil (1425mg pharmaceutical grade concentrate per softgel).
  • Convenient 'one-per-day' dosing.
  • Sourced from smaller fish (sardine, mackerel, anchovy) known for lower mercury levels.
  • Very competitive price per serving for its strength.
  • Positive reviews indicate user satisfaction and effectiveness.
Cons
  • Specific EPA and DHA amounts are not explicitly listed in the provided data.

Report overview

Categories

This product stands out in the fish oil category due to its 'ultra strength' and 'pharmaceutical grade' concentrate, offering a high dose in a convenient one-per-day format. Its competitive pricing for the potency makes it an excellent choice for consumers prioritizing efficacy and value within the fish oil market.

Goals

With a substantial amount of pharmaceutical-grade fish oil concentrate in a convenient one-per-day dose, this product effectively supports overall cellular health, reduces systemic inflammation, and contributes robustly to general well-being.
The high concentration of omega-3s is excellent for cardiovascular support, assisting in maintaining healthy triglyceride levels and promoting arterial elasticity, key factors for heart health. The 'pharmaceutical grade' implies high purity, which is also beneficial for long-term heart health.
DHA, derived from highly concentrated fish oil, is crucial for neuronal membrane integrity and cognitive function. A strong daily dose supports mental clarity, memory, and overall brain health, making this product highly effective for brain support.
