Beef liver is more than a source of iron. It delivers a naturally occurring combination of essential nutrients that work together to support energy, healthy blood, normal liver function, and everyday wellness.
A naturally bioavailable form of iron
Heme iron is generally absorbed more efficiently than the non-heme iron found in many plant foods. Iron supports normal red blood cell production, oxygen transport, and everyday energy.
Supports energy and normal nerve function
Vitamin B12 contributes to normal energy metabolism, red blood cell formation, nervous-system health, and healthy cognitive function.
Preformed vitamin A, also known as retinol
Vitamin A supports normal vision, immune health, skin maintenance, and healthy cellular function. Beef liver provides it in a directly usable preformed form.
An essential trace mineral
Copper works alongside iron and supports normal connective tissue, energy production, nervous-system function, and antioxidant protection.
Naturally occurring vitamin B9
Folate supports normal cell division, DNA synthesis, red blood cell formation, and healthy homocysteine metabolism.
Nutrients involved in cellular energy and antioxidant support
Beef liver contains compounds involved in normal cellular energy production and the body’s natural antioxidant defence systems.

Nutrients such as heme iron, vitamin B12, and preformed vitamin A occur naturally in beef liver and can be readily used by the body.
Freeze-dried capsules make it easier to add nutrient-dense organ nutrition to your routine without cooking, preparation, or the strong taste of fresh liver.
Beef liver has long been valued as a concentrated source of naturally occurring vitamin A, vitamin B12, heme iron, copper, folate, and other essential nutrients.
The problem is simple: many people do not enjoy the strong taste, texture, or preparation required to eat fresh liver regularly. Lonvera provides the nutritional convenience of freeze-dried grass-fed beef liver in easy-to-take capsules.
Each batch is sourced from grass-fed, pasture-raised cattle and carefully freeze-dried at low temperatures to help preserve its naturally occurring nutrient profile.
Across many traditional food cultures, organ meats were valued for their exceptional nutrient density and were often reserved for growing children, expecting mothers, hunters, elders, and others needing nourishing foods. Lonvera brings this traditional whole-food nutrition into a simple modern format that fits easily into your daily routine.
Beef liver has long been recognized as one of the most concentrated whole-food sources of vitamin A, vitamin B12, heme iron, copper, folate, and other naturally occurring nutrients.
Whole-Food Nutrition
Beef liver is unusually nutrient-dense, providing several essential vitamins and minerals together in one whole-food source. For people who do not enjoy eating fresh liver, freeze-dried capsules can offer a more convenient way to include organ nutrition in their routine.Naturally rich in iron, B12 and vitamin A
Micronutrients & Energy Metabolism
Heme iron, vitamin B12, folate, copper, and vitamin A each contribute to important normal functions in the body. Beef liver is notable because it naturally provides these nutrients together rather than isolating them into a heavily formulated synthetic blend.A naturally occurring nutrient matrix
Traditional Nutrition
Organ meats have been valued across many traditional diets because they provide exceptional nutrition in small servings. Careful freeze-drying offers a practical modern format while avoiding the preparation, texture, and strong flavour of eating fresh liver.Traditional nutrition made convenient
Everyone responds differently. Some customers report noticing changes in their daily energy and overall wellbeing within the first one to two weeks, while other benefits may take longer to become noticeable.
For the best experience, take the capsules consistently as directed and give your body time to adjust to the nutrient-dense formula. Results depend on your diet, health, lifestyle, and existing nutritional needs.
Beef liver naturally contains vitamin A in the form of retinol, along with iron, folate, copper, and vitamin B12. Because excessive preformed vitamin A may not be appropriate during pregnancy, consult your doctor, midwife, or OB-GYN before using this product while pregnant or breastfeeding.
Your healthcare provider can determine whether the product and serving size are appropriate for your individual nutritional needs.
Follow the serving directions shown on your bottle. The manufacturer recommends beginning with a smaller serving and taking the capsules with a meal while your body adjusts.
Do not exceed the recommended serving. Speak with a healthcare professional before use if you already take iron, vitamin A, copper, or other nutrient supplements.
Lonvera Beef Liver provides several naturally occurring nutrients, including vitamin A, vitamin B12, heme iron, copper, and folate. However, it does not necessarily provide every vitamin and mineral found in a complete multivitamin.
Whether it can replace your current multivitamin depends on your diet, health, and nutritional requirements. Ask your healthcare provider before replacing a supplement they have recommended.
The liver is enclosed inside sealed capsules, so most people do not experience the strong flavour or texture associated with eating fresh liver.
A mild natural scent may be noticeable when opening the bottle, but the capsules are designed to be swallowed quickly with water and a meal.
Consult your doctor or pharmacist before using the product if you take prescription medication, blood thinners, iron supplements, vitamin A products, or medication for a diagnosed condition.
You should also seek medical advice before use if you have a condition that affects iron storage, copper metabolism, liver function, or vitamin A processing.
Grass-fed generally means cattle consumed grass during their lives. Grass-finished means they continued eating a forage-based diet through the final stage of raising rather than being switched to a grain-based finishing diet.
Lonvera uses beef liver sourced from grass-fed and grass-finished cattle to provide a straightforward whole-food organ supplement.
