Is Liver Powder Good For Your Health?

Is liver powder good for your health?

 

Squid liver powder is a dark brown powder obtained by removing impurities from fresh squid liver, cleaning it, low-temperature drying it, and ultrafinely grinding it. Its biggest selling point is that it "concentrates all the nutrients in squid liver," but its true health benefits depend on the individual and dosage.

Average healthy individuals
• Squid liver contains approximately 20% to 30% fat, of which EPA and DHA account for over 30% of the total fatty acids. Consuming 1 to 2 grams of liver powder daily can provide 50 to 100 mg of omega-3 fatty acids, which help lower triglycerides, improve blood vessel elasticity, and relieve fatigue for those who frequently use their brains and eyes.
• Liver powder is rich in vitamins A and D. Each gram of dry powder contains approximately 2000 IU of vitamin A, equivalent to 40% of the recommended daily intake; and approximately 100 IU of vitamin D, which aids in calcium absorption and helps prevent osteoporosis. • Due to its high concentration, it's also rich in B vitamins, zinc, and selenium, making it a "natural multivitamin" for those with unbalanced diets.

 

People Who Need to Limit Intake?
• Vitamin A is fat-soluble, and long-term intakes >3000 μg RAE/day can lead to cumulative toxicity. Pregnant women and those with liver disease should avoid supplementing with high doses of liver powder.
• Squid liver, as a detoxifying organ, carries a risk of accumulation of heavy metals (cadmium, mercury) or ciguatera toxins if the raw material comes from polluted waters. Therefore, be sure to verify the "distant-sea fishing + heavy metal test report" when purchasing.
• Liver powder has a high purine content, so people with gout and high uric acid levels should limit their consumption to <1g per serving and no more than three times per week.

Cooking Fresh Squid Liver Instantly
If you're not making a dry powder and want to cook it directly, we recommend three methods:
• Sautéed Liver Tips: Heat oil and sauté garlic and ginger until fragrant. Add the squid liver and stir-fry over high heat for 30 seconds. Add cooking wine, light soy sauce, and oyster sauce, and finally garnish with basil.
• Pasta with Liver Paste: Crush the steamed squid liver and simmer with butter, heavy cream, and black pepper to create a thick liver paste. Toss with pasta.
• Clear Soup for Nourishing Liver: Boil the squid liver with tofu, goji berries, and sliced ​​ginger for 5 minutes. The broth will be milky white and smooth.

Does Liver Powder Contain Iron?

Many people equate "liver powder" with "iron supplementation," but the iron content of different animal livers varies greatly. According to data from the Fujian Fisheries Research Institute, every 100g of dried squid liver powder contains approximately 8-12mg of iron. While not considered "extremely high" compared to pork liver powder (18-22mg/100g), it still ranks among animal-derived foods with a high iron content.

Absorption Rate

Squid liver contains heme iron, with an absorption rate of 15%-35%, significantly higher than plant-derived non-heme iron (3%-8%). For people with mild iron deficiency anemia, a daily supplement of 2g of liver powder can provide 0.3-0.4mg of absorbable iron, equivalent to 3%-5% of the recommended daily intake. This supplement is acceptable as a dietary supplement but should not replace iron therapy.

Synergistic Nutrients
• Vitamin A promotes the synthesis of iron transporters, aiding iron transport to the bone marrow.
• Copper (approximately 0.5mg/100g of squid liver powder) is involved in the formation of ceruloplasmin and is an essential cofactor for ferroxidase.
• A moderate amount of vitamin C can further enhance iron absorption and is recommended for consumption with orange juice.
