Organ meats, or offal, were a dietary staple for our ancestors, prized for their concentrated nutritional benefits compared to traditional muscle meat. Among these, lamb heart stands out as an exceptionally nourishing and versatile cut. Often overlooked, it offers a dense profile of vitamins, minerals, and a uniquely valuable compound called Coenzyme Q10 (CoQ10). This article delves into the specific nutritional benefits and how this affordable and flavourful meat can be incorporated into a balanced diet.
What is the Nutritional Value of Lamb Heart?
As a highly active muscle, the lamb heart is rich in specific micronutrients. Per 100 grams of cooked lamb heart, you can expect a significant intake of essential vitamins and minerals. It provides a robust amount of protein (around 25g) and a moderate amount of fat (around 8.5g), which includes beneficial omega-3 fatty acids.
Key Vitamins in Lamb Heart
Lamb heart's vitamin profile is one of its most impressive features. It is packed with B-complex vitamins that are crucial for energy production and overall cellular health.
- Vitamin B12: A 100g serving of cooked lamb heart can provide well over 180% of the daily value, a critical nutrient for red blood cell formation, neurological function, and DNA synthesis.
- Riboflavin (B2): An excellent source of riboflavin, which supports energy metabolism and acts as an antioxidant.
- Niacin (B3): Contains a good amount of niacin, a vitamin known to support healthy cholesterol levels.
- Thiamin (B1): This vitamin helps convert carbohydrates into energy for the brain and nervous system.
- Pantothenic Acid (B5): A good source of B5, which is essential for hormone production and converting food into usable energy.
Essential Minerals
Beyond its vitamin content, lamb heart is laden with essential minerals that contribute to numerous bodily functions.
- Iron: It is a good source of highly bioavailable heme iron, which helps prevent anaemia and supports oxygen transport throughout the body.
- Selenium: This trace mineral acts as a powerful antioxidant and plays a role in regulating thyroid function.
- Zinc: An excellent source of zinc, which is vital for immune function, wound healing, and metabolic health.
- Copper: Provides a significant amount of copper, which helps regulate energy production and iron metabolism.
- Phosphorus: An important mineral for building strong bones and teeth.
How Lamb Heart Compares to Other Meats
To truly appreciate the nutrient density of lamb heart, it helps to compare it with standard lamb muscle meat. While both are nutritious, organ meats like the heart offer a different micronutrient profile.
| Nutrient | Lamb Heart (per 100g, cooked) | Lamb Muscle Meat (per 100g, cooked) | Key Differences |
|---|---|---|---|
| Calories | ~185 kcal | ~294 kcal | Lamb heart is often leaner, with fewer calories per gram. |
| Protein | ~25g | ~24.5g | High and comparable protein content, but heart provides a full amino acid profile. |
| Fat | ~8.5g | ~21g | Muscle meat generally has significantly more fat. |
| Vitamin B12 | ~11.2 mcg (187% DV) | ~2.6 mcg | Lamb heart is an exponentially richer source of Vitamin B12. |
| Iron (Heme) | 5.0-5.9 mg | ~2.2 mg | A more concentrated source of highly bioavailable heme iron. |
| CoQ10 | Rich source | Lower levels | Lamb heart contains higher levels of this crucial compound for energy. |
Culinary Versatility and Cooking Tips
Due to its muscle-like texture, lamb heart is incredibly versatile in the kitchen. To avoid a tough or rubbery texture, you should either cook it very quickly over high heat or very slowly over low heat.
- Quick Cooking: Thinly slice the heart and flash-fry it in a pan or grill it over high heat. Marinating with herbs and spices can enhance its deep, robust flavour.
- Slow Cooking: Braising the heart in a flavorful liquid, like stock or red wine, ensures a melt-in-your-mouth tender result. This method works perfectly for stews or casseroles.
- Stuffing: The heart's natural shape makes it ideal for stuffing.

Conclusion: Embracing Lamb Heart for Health
As a nutrient-dense and versatile organ meat, lamb heart presents a compelling case for re-evaluating our dietary choices. Rich in high-quality protein, essential vitamins like B12, and vital minerals such as iron and zinc, it is a powerhouse for supporting energy production, muscle health, and a robust immune system. Whether braised slowly for a tender and hearty meal or flash-fried for a quick and flavourful bite, lamb heart is a delicious and highly nutritious food that honours a more ancestral approach to eating. By including it in your diet, you tap into a wellspring of nutrition that is often overlooked in modern cuisine.
