Beef organ complex (desiccated)
What it is
Freeze-dried concentrates of beef liver, heart, kidney, and spleen providing heme iron (2.5× more absorbable than plant-based iron), vitamin B12, copper, CoQ10, and fat-soluble vitamins in their natural food matrix. A 2023 observational study found desiccated liver users had significantly higher serum B12 and ferritin than matched controls. No large RCTs exist. Primary risk: vitamin A toxicity from concentrated liver at high doses — beef liver contains 6,000–9,000 mcg retinol equivalent per 100 g. Also high in purines (gout risk). Those with iron overload conditions (haemochromatosis) should avoid.
Dose
3–6 capsules/day (typically 500 mg each) of grass-fed freeze-dried beef organ blend. Do not exceed label recommendation due to vitamin A accumulation.
Time of day & tips
Source from grass-fed, freeze-dried products for best nutrient retention. Do not combine with standalone vitamin A supplements — toxicity risk accumulates silently. Space from levothyroxine (iron content). Avoid if haemochromatosis, gout, or taking retinol supplements.
Cycling
Safe at standard doses (3–4 capsules/day). Monitor retinol status if using long-term at high doses. Seasonal variation in nutrient content of grass-fed products is normal.
