Halibut Nutrition Facts
Per 3-oz (85g) serving of cooked Pacific halibut:
| Nutrient | Amount | % Daily Value |
|---|---|---|
| Calories | ~110 | — |
| Protein | ~21g | ~42% |
| Total fat | ~2.3g | ~3% |
| Omega-3 (EPA+DHA) | ~400–500mg | — |
| Vitamin B12 | ~1.2mcg | ~50% |
| Vitamin B6 | ~0.4mg | ~25% |
| Selenium | ~40mcg | ~73% |
| Magnesium | ~28mg | ~7% |
| Potassium | ~490mg | ~10% |
| Phosphorus | ~242mg | ~19% |
| Mercury (avg) | ~0.241 ppm | FDA "good choice" category |
Omega-3 context: Halibut has moderate omega-3 content — approximately 400–500mg EPA+DHA per 3-oz serving. This is meaningful but lower than fatty fish like King salmon (~1,500–2,000mg), sockeye salmon (~1,000–1,200mg), or sablefish (~1,500mg). Halibut's omega-3 content is comparable to cod and other lean white fish. For maximum omega-3 intake, pair halibut with higher-omega-3 fish in your weekly rotation.
Mercury context: Pacific halibut has an average mercury level of approximately 0.241 ppm — in the FDA's "good choice" category (eat 1 serving per week). This is significantly lower than high-mercury fish like swordfish (0.995 ppm) or shark (0.979 ppm), but higher than very low-mercury fish like salmon (0.022 ppm) or shrimp (0.009 ppm). Pacific halibut is safe for most adults at 1–2 servings per week; pregnant women and young children should follow the FDA's "good choice" guidance of 1 serving per week.
Why Halibut is a Nutrient-Rich Choice
Halibut is packed with vital nutrients that support overall health, including high-quality protein, heart-healthy omega-3 fatty acids, and essential vitamins and minerals. Here's what makes halibut a nutrient-dense choice:
- High Protein Content: A 3-oz serving of halibut contains approximately 21g of lean protein — 42% of the daily value — essential for muscle growth, repair, and satiety.
- Omega-3 Fatty Acids: Approximately 400–500mg EPA+DHA per 3-oz serving — a meaningful contribution to the recommended 250–500mg daily intake, though lower than fatty fish like salmon.
- Exceptional Selenium Content: A single 3-oz serving provides approximately 73% of the daily value for selenium — one of halibut's most significant nutritional advantages. Selenium is a powerful antioxidant that supports thyroid function and immune health.
- Rich in B Vitamins: Halibut provides approximately 50% of the daily value for vitamin B12 and 25% for vitamin B6 — both essential for energy metabolism, nerve function, and red blood cell production.
According to the American Heart Association, "eating fish high in Omega-3s at least twice a week has been shown to lower the risk of cardiovascular disease," making halibut a good contributor to a heart-healthy diet.
Key Health Benefits of Halibut
1. Supports Heart Health
Halibut is a heart-healthy food due to its omega-3 fatty acid content and its high potassium level (~490mg per 3-oz serving — approximately 10% of the daily value). Omega-3s help reduce inflammation, lower triglycerides, and decrease blood pressure; potassium helps counteract sodium's effects in the body, further supporting cardiovascular health. Regular consumption of omega-3-rich fish like halibut is associated with a reduced risk of heart disease and stroke.

2. Boosts Brain Function and Cognitive Health
The omega-3s in halibut — particularly DHA — support brain health by improving cognitive function and reducing the risk of cognitive decline. DHA is a key component of brain cell membranes and helps enhance communication between brain cells. Halibut's vitamin B12 content also supports neurological function and helps prevent cognitive decline associated with B12 deficiency.
3. Provides High-Quality Protein for Muscle Health
As a lean source of complete protein (containing all essential amino acids), halibut is excellent for supporting muscle repair and growth, especially for those with active lifestyles. The protein in halibut also contributes to satiety, helping to keep you full and reduce unhealthy snacking between meals.
For a protein-packed meal ideal for grilling or baking, try Global Seafoods' halibut steaks .
4. Supports Strong Bones and Joints
Halibut is an excellent source of phosphorus (~19% DV per 3-oz serving) and magnesium (~7% DV), which are essential for maintaining bone density and strength. Phosphorus and magnesium work together to help build and repair bone tissue, while potassium helps maintain muscle and bone health by balancing calcium levels.
5. Rich in Selenium for Immune Support and Thyroid Health
Halibut's most impressive micronutrient is selenium — approximately 73% of the daily value per 3-oz serving. Selenium is a powerful antioxidant that protects cells from oxidative damage, supports thyroid hormone metabolism, and boosts immune defenses. Few foods provide this level of selenium in a single serving; halibut is one of the best dietary sources available.
For a unique option, try halibut cheeks , which offer the same nutrient-rich profile in a delicate, tender cut that's perfect for pan-searing.
6. May Help with Weight Management
Due to its high protein content and very low fat (~2.3g per 3-oz serving), halibut is an excellent choice for weight management. At approximately 110 calories per 3-oz serving, it provides substantial protein and satiety with minimal caloric density. The omega-3s in halibut have also been shown to reduce inflammation, which can sometimes interfere with weight regulation.
7. Promotes Heart and Muscle Health with Potassium
Potassium is an essential mineral for maintaining normal heart function, muscle contractions, and nerve signaling. Halibut provides approximately 490mg of potassium per 3-oz serving — about 10% of the daily value — which helps counteract sodium's effects in the body, lowering blood pressure and supporting heart and muscle health.
How to Select and Store Fresh Halibut
Tips for Buying Fresh Halibut
- Look for Clear, Bright Eyes (if buying a whole fish): Fresh halibut will have clear, bright eyes. Cloudy eyes are a sign the fish isn't fresh.
- Check the Smell: Fresh halibut should have a mild, oceanic scent. Avoid any fish with a strong or "fishy" odor.
- Inspect the Flesh: Fresh halibut fillets should be firm, slightly translucent, and free of discoloration. Fillets should have a slight sheen and be moist but not slimy.
