Top Animal Sources of Magnesium
While plant-based foods often get the spotlight for magnesium content, many animal products contribute significantly to a balanced diet. The concentration varies depending on the product, with some of the richest sources coming from the sea.
Seafood: The Magnesium Powerhouse
Seafood is arguably the most potent animal-based source of magnesium. Fatty fish and shellfish offer substantial amounts.
- Chinook Salmon: 100 grams provides a large portion of daily needs.
- Mackerel: Atlantic mackerel offers a notable amount.
- Anchovies: Canned anchovies also serve as a concentrated source.
- Shellfish and Crustaceans: King crab, oysters, and shrimp contribute to magnesium intake.
Dairy Products: Accessible Sources
Dairy can be a reliable and accessible source of magnesium, with content varying by product type.
- Fortified Milk Powders: Some contain significantly higher amounts per 100 grams.
- Whey Protein Powder: Similar to other milk-based powders.
- Dry Milk: Powdered or dry milk offers a good amount.
- Cheeses: Certain cheeses, like Parmesan and Swiss, offer a decent helping.
Meats and Organ Meats
Meats and organ meats contribute to overall intake, though generally containing less magnesium per serving than seafood or dairy.
- Beef: A 100-gram serving provides a moderate amount. Grass-fed beef may offer slightly more nutrients.
- Poultry: Chicken breast and turkey contain modest levels.
- Pork: Most cuts have lower levels, but products like bacon can provide a moderate boost.
- Organ Meats: Some, like beef liver, offer magnesium, often in smaller amounts compared to other animal sources.
Comparison Table: Magnesium in Common Animal Products
| Animal Product | Approximate Magnesium (mg per 100g) | Notes |
|---|---|---|
| Chinook Salmon (cooked) | 122 mg | Excellent source of omega-3s and other minerals. |
| Atlantic Mackerel (cooked) | 97 mg | A flavorful and affordable fatty fish option. |
| King Crab (cooked) | 63 mg | Also rich in zinc and other essential minerals. |
| Oysters (cooked) | 58 mg | Contains high levels of zinc and B vitamins. |
| Parmesan Cheese | 38-44 mg | A hard cheese that adds flavor to many dishes. |
| Chicken Breast (roasted) | 22-34 mg | A very common and lean protein source. |
| Beef, Mince (cooked) | 18-21 mg | Provides other key nutrients like iron and zinc. |
| Whole Milk (3.25% fat) | 98-110 mg/L | Easily accessible, but requires larger quantities for notable intake. |
The Role of Bioavailability
Bioavailability of magnesium from different food sources is important. Plant foods can contain oxalates and phytates that hinder absorption, but animal products generally do not have these inhibitors. Overall dietary quality and kidney function also affect absorption. A variety of sources is the best strategy.
Conclusion
Animal products provide valuable, bioavailable magnesium, with seafood offering high concentrations. Dairy and meats contribute to daily intake and are important for those on restrictive diets. A balanced diet incorporating various protein sources helps ensure adequate intake for optimal health.
The Importance of Dietary Diversity
Combining animal and plant-based foods is recommended for a complete nutritional profile. Plant sources like leafy greens, nuts, and seeds are high in magnesium, and their combination with animal sources maximizes intake and balance.
Considerations for Specific Diets
Individuals on diets like the carnivore diet need to focus on magnesium sources. While meat and fatty fish provide some, including higher intake of certain types of fish or longer-cooked bone broth can help.
Recipe Ideas Featuring Magnesium-Rich Animal Products
Here are some simple ideas:
- Salmon Salad: Cooked Chinook salmon with mayonnaise, celery, and lemon.
- Mackerel Patties: Canned mackerel, herbs, and breadcrumbs, pan-fried.
- Cheese and Meat Platter: Parmesan and Swiss cheese with dried meat.
- Shrimp Scampi: Sautéed shrimp with garlic, olive oil, and butter.
- Yogurt Parfait: Plain yogurt with berries and nuts.
Key Takeaways for Magnesium Intake
- Seafood is Best: Fatty fish like salmon and mackerel, and shellfish, are top animal sources.
- Dairy Contributes: Yogurt, cheese, and milk are reliable sources, with fortified options offering high doses.
- Meat has Less: Meats like beef and chicken offer moderate amounts.
- Fortified Options Boost Intake: Protein powders and dry milk can be high-dose sources.
- Bioavailability is High: Animal products offer highly bioavailable magnesium.
- Variety is Important: Combine animal products with leafy greens, nuts, and seeds for comprehensive nutrition.
- Consider Cooking Time: Longer cooking of bone broth can extract more magnesium.
The Bottom Line
A range of animal products can help meet daily magnesium requirements for those who include them in their diet. Prioritizing seafood, utilizing dairy, and including various meats ensures a steady supply. A mindful approach to diet incorporating diverse sources supports overall health.

FAQs
What is the richest animal source of magnesium?
Fatty fish, such as Chinook salmon and Atlantic mackerel, are among the richest animal sources.
Can I get enough magnesium from a carnivorous diet alone?
It is possible with careful planning, focusing on options like fatty fish and bone broth, though many plant foods have higher concentrations.
Is magnesium in dairy products easily absorbed?
Yes, magnesium in dairy is readily absorbed.
Do all animal meats contain the same amount of magnesium?
No, levels vary; fatty fish and shellfish typically contain more than muscle meats.
How does cooking affect the magnesium content in animal products?
Cooking doesn't majorly impact content, though some loss can occur in water if not consumed. Longer cooking for bone broth can increase content.
Are eggs a good source of magnesium?
Eggs contain some, but are not a highly concentrated source; most is in the yolk.
How do I increase my magnesium intake from animal products?
Focus on fatty fish, shellfish, and dairy products.
Can I overdose on magnesium from food?
No, it's highly unlikely from food sources alone.
Which animal products are best for someone on a budget?
Canned fish like mackerel and anchovies, ground beef, and chicken breast are budget-friendly options.
Are there any animal-based magnesium supplements?
Bone meal and some protein powders are animal-based and can provide magnesium.
Should I prioritize animal or plant sources for magnesium?
A combination of both is usually best for a well-rounded diet, considering that while plants can have higher concentrations, animal-based magnesium is highly bioavailable.
