Analysis

The serving provides 360 mg total omega-3 from 1,200 mg fish oil, which is a basic concentration. Vitamin D contributes 25 mcg as a separate nutrient relevant to bone and immune nutrition.

The EPA and DHA entries do not provide usable amounts, and the molecular form is not stated. No fish species, antioxidant, purity standard, or oxidation measure appears in the supplied data.

Low serving cost makes the combination convenient for users who need both nutrients. People already taking vitamin D should count this amount toward their total daily intake.

Who is it for
  • Adults who need both basic fish oil and vitamin D3
  • Budget-conscious users
  • People tracking total vitamin D intake
Best for
  • Combining two daily supplements
  • General omega-3 intake
  • Vitamin D maintenance

Pros

  • Includes 25 mcg vitamin D
  • Low serving cost
  • One-softgel routine

Cons

  • Only 360 mg total omega-3
  • EPA and DHA are not quantified
  • No molecular-form or purity details

Warnings

  • People with fish allergy should avoid fish-oil supplements unless their allergy specialist says otherwise.
  • Fish oil can increase bruising or bleeding tendency with anticoagulant or antiplatelet medicines, especially at higher total omega-3 intakes.
  • The 25 mcg vitamin D serving should be counted with other vitamin D supplements and fortified foods.

Nutrient quality

63 Moderate impact

The focused fish-oil formula avoids low-value extras. Modest active concentration and an unspecified oil form limit dose and absorption confidence.

Ingredient transparency

61 Moderate impact

The label states total omega-3 and serving count. Separate EPA and DHA amounts, other ingredients, full directions, and key sourcing or quality details remain missing.

Customer satisfaction

70 High impact

The aggregate satisfaction signal is strong and supported by the available response volume. No review-text evidence is provided to assess repeated complaints or whether experiences match the intended use.

Value for money

60 Moderate impact

The formula remains reasonably priced for basic fish-oil use. Modest active concentration and missing EPA and DHA detail reduce value per effective serving.

Vitamin D · 25 mcgFish Oil · 1200 mg

Fish oil and vitamin D have relevant inflammation-related roles, but the active omega-3 dose cannot be verified. EPA and DHA are recorded without usable amounts.

Vitamin D3 adds a complementary immune-regulatory pathway, yet the fish-oil source, molecular form, and purity controls are absent. Fish oil may increase bleeding tendency when combined with anticoagulant or antiplatelet medicines.

Vitamin D · 25 mcgFish Oil · 1200 mg

Fish oil is highly relevant to cardiovascular support, but total fish-oil weight does not reveal how much active EPA and DHA the serving provides. The disclosed total omega-3 amount is modest and cannot be tied confidently to triglyceride or endothelial benefits.

Vitamin D3 adds general nutritional support but does not compensate for missing fish source, molecular form, purification, or oxidation details. Undisclosed EPA and DHA amounts make the effective dose and practical value impossible to judge.

Report overview
Omega-3 · 360 mg OverallScore40
F Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyA+ Value

The formula supplies a relatively low share of omega-3 from generic fish oil and does not identify the molecular form. Vitamin D adds a separate nutrient but does not resolve the missing EPA and DHA breakdown. The low serving cost is favorable, though purity testing and oxidative protection are not stated.

Fish Oil · 1200 mg OverallScore3
F Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value

The formula adds vitamin D3, but it does not disclose usable EPA and DHA amounts. Fish source, molecular form, purification, independent testing, and antioxidant protection are also missing. Value for active omega-3 cannot be established from total omega-3 alone.
