Turkey Heart

What It Is

Fresh turkey heart organ, rich in CoQ10, taurine, B vitamins, iron, and highly digestible protein.

Compare to Similar Ingredients

• vs. chicken heart: Both are nutrient-dense heart muscle organs. Turkey heart is from turkeys and slightly larger, while chicken heart is from chickens—both are excellent sources of taurine, CoQ10, and B vitamins.
• vs. turkey liver: Both are turkey organ meats. Turkey heart is muscle tissue rich in taurine and CoQ10 for heart health, while turkey liver is the detox organ packed with vitamin A, iron, and folate.

Why It's Used in Dog Products

Manufacturers include turkey heart in dog food, treats, and supplements for several reasons:

• Nutrient-dense organ meat
• Natural CoQ10 for heart health
• Rich in taurine for heart/eyes
• High-quality lean protein

Quality Considerations

Turkey heart is one of the safest organ meats to feed—unlike liver, it has no vitamin A toxicity concerns and can make up 10-20% of diet safely. As cardiac muscle, it's uniquely rich in taurine (150-250mg/100g) and CoQ10, both critical for heart function. Look for "turkey heart" (species-specific) rather than generic "poultry hearts." Especially valuable for breeds prone to DCM or dogs on grain-free diets. Indicates a whole-prey nutrition approach when combined with other organ meats.

Scientific Evidence

Turkey heart is organ meat from turkeys, specifically the cardiac muscle. Heart is technically a muscle organ rather than a glandular organ, composed primarily of cardiac muscle tissue. The ingredient provides approximately 17-20% protein and 8-10% fat on a fresh weight basis (which includes natural moisture of about 70%). The protein is highly digestible with a complete amino acid profile. Turkey heart is particularly rich in taurine, an amino acid-like compound that is essential for dogs, especially important for cardiac function. The ingredient provides high levels of CoQ10 (coenzyme Q10), an antioxidant important for cellular energy production and cardiac health. Turkey heart is rich in B vitamins, particularly B12, niacin, and riboflavin, along with minerals including iron (heme iron with high bioavailability), zinc, selenium, and phosphorus. The fat content includes both saturated and unsaturated fatty acids. As an organ meat, turkey heart is more nutrient-dense than turkey muscle meat, though less concentrated in certain vitamins than glandular organs like liver. The ingredient is highly palatable to most dogs. Quality depends on sourcing, with organic or pasture-raised turkey hearts generally preferred over conventional sources.

Key Research Findings

• Rich in taurine, essential for cardiac function in dogs
• High in CoQ10, important for cellular energy and heart health
• Provides highly bioavailable heme iron and complete protein
• Contains approximately 17-20% protein, 8-10% fat on fresh basis

Evidence Level: Moderate - based on organ meat composition data and general nutrient bioavailability research, with limited turkey heart-specific studies in dogs

How to Spot on Labels

Reading ingredient labels can be confusing. Here's how to identify and evaluate this ingredient:

What to Look For

• Listed as 'turkey heart' or 'turkey hearts' in ingredient panel
• Species-specific designation indicating transparent sourcing
• Common in premium and organ-inclusive formulas
• May be marketed for taurine content in cardiac support formulas

Alternative Names

This ingredient may also appear as:

• Turkey hearts
• Dehydrated turkey heart (if moisture removed)
• Turkey heart meal (if rendered and dried)

Red Flags

• Generic 'heart' or 'poultry heart' without species specification
• Listed far down ingredient list despite marketing emphasis on organ content
• No information about sourcing or quality

Green Flags

• Listed in first 7 ingredients, indicating meaningful inclusion
• Organic, free-range, or pasture-raised designation
• Part of diverse organ meat inclusion (heart, liver, kidney, etc.)
• Specific sourcing information provided

Typical Position: First 5-10 ingredients in premium organ-inclusive formulas. Organ meats typically listed after primary muscle meat sources.
