These are supplements made from freeze-dried beef liver (usually from grass-fed cows). They are often called a “natural multivitamin” because they contain high levels of nutrients like:

Vitamin A (retinol)

Vitamin B12

Iron (heme iron)

Choline, folate, copper

They are designed for people who don’t want to eat liver but still want its nutrients.

✅ Benefits

One of the richest sources of vitamin A, B12, and iron

2. Boosts energy & reduces fatigue

B12 + iron help with red blood cells and oxygen transport

May improve tiredness, especially if deficient

3. Supports immunity & skin health

Vitamin A and antioxidants help immune function and skin repair

4. Better nutrient absorption

⚠️ Cons

Reddit users also warn: “They can skyrocket iron levels… start low.”

3. Not a complete diet replacement

Supplements ≠ balanced diet
