How to get enough magnesium on a carnivore diet?

4 min read

According to research, a strict carnivore diet may be low in several key nutrients, including magnesium, as most magnesium-rich foods are plant-based. This guide explains how to get enough magnesium on a carnivore diet, focusing on nutrient-dense animal sources and supplementation strategies.

Quick Summary

This article outlines food-based and supplemental strategies to obtain adequate magnesium while following a carnivore diet. It details specific animal sources rich in magnesium, explains why deficiency can occur, and provides practical steps for proper electrolyte replenishment.

Key Points

  • Fatty Fish is King: Prioritize fatty fish like salmon, mackerel, and sardines, as they are among the highest magnesium sources on a carnivore diet.

  • Consider Supplements: For individuals with high needs or persistent deficiency symptoms, a bioavailable magnesium supplement like glycinate or malate may be necessary to ensure adequate intake.

  • Don't Forget Bone Broth: Slow-simmered bone broth is a mineral-rich beverage that provides a host of electrolytes, including magnesium, aiding in overall mineral balance.

  • Rotate Your Protein: Varying your protein intake to include organ meats, shellfish, and fatty fish prevents over-reliance on muscle meat, which is lower in magnesium.

  • Watch for Symptoms: Monitor for signs of low magnesium such as muscle cramps, fatigue, and poor sleep, which indicate a need to adjust dietary intake or consider supplementation.

  • Be Mindful of Hydration: The low-carb nature of the carnivore diet can alter fluid balance, making it crucial to manage hydration and electrolytes properly, often with quality salt.

The Importance of Magnesium on a Carnivore Diet

Magnesium is an essential mineral involved in over 300 biochemical reactions in the body, including muscle function, nerve transmission, energy production, and heart rhythm regulation. When following a carnivore diet, the significant reduction or elimination of plant-based foods—which are typically primary sources of magnesium—can increase the risk of a deficiency.

Symptoms of low magnesium levels can manifest as muscle cramps, fatigue, insomnia, heart palpitations, and headaches. This is particularly relevant for those on a low-carbohydrate diet, as reduced insulin levels can cause the kidneys to excrete more electrolytes, including magnesium. Ensuring proper magnesium intake is vital for mitigating these 'keto flu' symptoms and supporting overall health and well-being on an all-animal diet.

Food Sources of Magnesium for Carnivores

While meat is not as rich in magnesium as leafy greens or nuts, certain animal products are excellent sources that can help meet your daily needs. Diversifying your protein sources is key to maximizing mineral intake.

Prioritize Seafood

Many types of seafood offer significantly more magnesium than muscle meats. Incorporating a variety of fatty and smaller fish can provide a substantial boost to your intake. For example, Chinook salmon contains approximately 122 mg per 100 grams, and fatty fish like mackerel and sardines are also excellent sources. Shellfish such as oysters and king crab provide notable amounts as well.

  • Fatty Fish: Atlantic Mackerel (97 mg/100g), Chinook Salmon (122 mg/100g), Anchovies (69 mg/100g), Sardines (58 mg/100g).
  • Shellfish: King Crab (63 mg/100g), Oysters (58 mg/100g), Mussels (37 mg/100g).

Incorporate Organ Meats and Bone Broth

Organ meats are nutrient-dense powerhouses that offer a wide array of vitamins and minerals. Beef liver, while not the highest source of magnesium, still contributes meaningfully to overall intake. Bone broth is another valuable addition, especially when simmered for a longer duration, as it contains a variety of electrolytes and minerals, including magnesium.

Include Dairy and Eggs (If Tolerated)

For those who include dairy in their carnivore approach, full-fat cheeses and other dairy products can provide a supplemental source of magnesium. Parmesan and sharp cheddar are among the better options. Eggs, while not exceptionally high in magnesium, offer a host of other nutrients and are a staple of many carnivore diets.

Comparing Carnivore Magnesium Sources

Food Source Magnesium Content (per 100g) Notes
Chinook Salmon 122 mg Excellent, high-potency option.
Atlantic Mackerel 97 mg Great fatty fish source.
Canned Anchovies 69 mg Convenient and concentrated source.
King Crab 63 mg Shellfish can be a good option.
Sardines 58 mg Contains edible bones for added calcium.
Parmesan Cheese 38 mg Good option for those tolerating dairy.
Beef Ribeye 22 mg (per 100g serving) Good, but requires larger volume.
Beef Liver 14–25 mg Rich in other nutrients, but modest in magnesium.
Bone Broth ~17 mg (per 8oz) Simmering longer increases mineral yield.

Magnesium Supplementation Options

Even with a varied carnivore diet, some individuals, especially athletes or those with underlying health issues, may struggle to meet their magnesium needs through food alone. In such cases, supplementation can be a safe and effective strategy.

When choosing a supplement, consider a bioavailable form that your body can absorb easily. Magnesium glycinate is a popular choice known for its high absorption and gentle effect on the digestive system. Other forms like magnesium citrate are also effective, though they can have a laxative effect in larger doses.

  • Magnesium Glycinate: Highly bioavailable and well-tolerated.
  • Magnesium Citrate: Effective, but may cause digestive upset.
  • Magnesium Malate: Often recommended for muscle support and energy production.
  • Electrolyte Powders: Many brands offer electrolyte mixes specifically formulated for low-carb diets, which often contain balanced amounts of magnesium, potassium, and sodium. Look for options without added sugars or artificial sweeteners.

Practical Tips for Maintaining Magnesium Balance

  • Listen to Your Body: Pay attention to symptoms like muscle twitches, cramps, or difficulty sleeping. These are common signs that your magnesium levels might be low.
  • Salt Liberally: A low-carb diet causes increased sodium excretion, which can also affect other electrolyte levels. Using a high-quality salt like Himalayan pink salt or Redmond Real Salt can provide trace minerals.
  • Stay Hydrated: Drink plenty of water, but be mindful not to overdo it. Excessive plain water can further dilute electrolyte levels. Consider adding a pinch of salt to your water.
  • Rotate Your Protein: Don't rely solely on muscle meat. Incorporate fattier fish, shellfish, and organ meats to get a wider spectrum of minerals.

The Carnivore Diet and Nutrient Density

While it's true that the standard sources for magnesium are plants, the carnivore diet eliminates many foods that can interfere with nutrient absorption. For example, phytic acid found in grains, legumes, and nuts can bind to minerals like magnesium and reduce their bioavailability. By removing these compounds, your body may be able to better absorb the magnesium from animal sources, which could partially offset the lower quantity. However, a careful and deliberate approach is still necessary to ensure adequacy. For those considering supplementing, it's always wise to consult with a healthcare professional before starting any new regimen.

Conclusion

While a carnivore diet presents a unique challenge for meeting magnesium requirements, it is certainly not an insurmountable one. By strategically prioritizing nutrient-dense animal foods such as fatty fish, shellfish, and bone broth, and supplementing with high-quality magnesium when necessary, you can maintain healthy magnesium levels. Paying close attention to your body’s signals and diversifying your food sources are the most effective strategies for long-term success and optimal health on this dietary path.

Further research continues to explore the exact nutrient requirements on a low-carbohydrate, animal-based diet. However, for those committed to the carnivore lifestyle, a proactive approach to electrolyte balance is a cornerstone of success.
