Kidney: A Naturally Nutrient-Dense Food
Beef kidney is a rich natural source of essential nutrients, including high-quality protein, B vitamins, minerals, and fat-soluble compounds. Traditionally valued in many cultures, kidney has been gaining renewed attention as a nutrient-dense whole food that supports general wellbeing.
A 100-gram serving of fresh kidney provides approximately 20 grams of protein, along with a range of micronutrients including:
- Vitamin B12 – supports energy metabolism, red blood cell formation, and nervous system health
- Riboflavin (Vitamin B2) – contributes to normal energy production and the reduction of tiredness and fatigue
- Iron – supports oxygen transport in the body and contributes to normal immune function
- Zinc – involved in normal immune function, wound healing, and macronutrient metabolism
- Selenium – contributes to the protection of cells from oxidative stress and supports healthy immune system function
- Vitamin A – supports the maintenance of normal vision, skin, and mucous membranes
-
Copper – contributes to normal iron transport and connective tissue formation
Folate (Vitamin B9) – supports normal blood formation and cell division -
Vitamin K2 – plays a role in bone maintenance and calcium metabolism
Why Whole Food Sources Matter
Nutrients in animal organs like kidney often occur in a naturally balanced and highly bioavailable form—meaning they are efficiently absorbed and utilised by the body. These foods also contain co-factors and enzymes that support digestion and metabolic activity.
While nutrient needs can be met through a varied diet, some individuals find it difficult to source, prepare, or consume organ meats regularly. In these cases, freeze-dried organ capsules can offer a practical alternative.
A Convenient Option: Freeze-Dried Kidney Capsules
Our Australian grass-fed beef organ supplements offer a convenient way to access the nutrients found in kidney without the need for preparation or taste tolerance. They are freeze-dried to help preserve nutritional integrity and are free from hormones, antibiotics, and GMOs.
Always read the label and follow the directions for use. Nutritional supplements should not replace a balanced diet.
