Short answer: gram for gram, yes. Freeze-dried liver is the same food with the water removed, so the iron, B12, retinol, folate and copper are substantially preserved. Serving for serving, no: a 3,000 mg capsule serving is roughly a tenth of a 100 g plate of fresh liver. Capsules deliver a smaller dose every single day; a liver dinner delivers a big dose you'll probably skip. Which "wins" depends on which of those you'll actually do.
Here's the arithmetic most brands would rather not print.
Freeze-drying: what survives, what doesn't
A proper liver capsule is raw liver, freeze-dried at low temperature, milled, capsuled. Freeze-drying removes water (fresh liver is roughly 70% water) without the high heat that degrades nutrients. What's left is the same food, concentrated by dryness: the heme iron, the ~70 µg of B12 per 100 g (fresh basis), the preformed vitamin A, folate, copper and choline. This is why "capsules vs fresh" isn't really a quality debate the way "fresh vs boiled-to-death" would be. Heat-dried powders are a different story (high heat is how liver becomes expensive dust), which is why freeze-dried is the spec worth checking.
The dose math, done openly
Now the part that matters. If fresh liver is roughly 70% water, then a 3,000 mg (3 g) serving of freeze-dried liver corresponds to roughly 10 g of fresh liver. A standard portion of cooked liver is about 100 g. So:
- One capsule serving ≈ roughly one-tenth of a liver dinner. Anyone telling you four capsules equals a plate of liver is selling arithmetic that doesn't check out.
- A month of daily servings ≈ roughly 90 g of freeze-dried liver, in fresh terms, on the order of three 100 g portions. That's remarkably close to the traditional "liver a few times a month" pattern, just divided into 30 painless daily doses.
Seen that way, capsules aren't a mega-dose or a magic upgrade. They're portion control: ancestral liver intake on a drip feed instead of a monthly feast.
Where fresh liver genuinely wins
Two places, and it's not close. Dose per dollar: butcher liver costs a few dollars and out-delivers any capsule on sheer nutrient volume per dollar spent. Dose per sitting: if your goal is a substantial intake of iron and B12 in one go, a 100 g portion does in one meal what capsules spread across a week and a half. If you like liver and will reliably eat it, you don't need us, and we mean that.
Where capsules genuinely win
Adherence. The best nutrition plan is the one that survives contact with a Tuesday. Capsules need no butcher, no smell, no recipe, no willpower, and that's why the drip feed usually beats the feast in practice: the feast keeps not happening. Consistency of intake also suits how nutrient status actually changes, steadily, over weeks. And the daily serving is deliberately food-scale: liver is rich in preformed vitamin A, and roughly a tenth of a portion per day keeps intake sensible rather than heroic (pregnant? talk to your practitioner first; that's on our own label).
If capsules are your route, the spec sheet matters: Rise Grass-Fed Beef Liver is one ingredient (freeze-dried grass-fed, grass-finished beef liver) in a gelatin capsule. $39.99 for 120 capsules; 4 capsules = 3,000 mg, so the bottle is a 30-day supply at about $1.33 a day. NPN certified by Health Canada, made in Canada, bilingual label.
FAQ
How many liver capsules equal 100 g of fresh liver?
Working from liver being roughly 70% water: 100 g fresh corresponds to roughly 30 g freeze-dried, about ten of Rise's 3,000 mg servings, or roughly 40 capsules. Which is exactly why capsules should be understood as a small daily dose, not a replacement plate of liver.
Do capsules lose nutrients compared to fresh liver?
Freeze-drying at low temperature is specifically chosen because it removes water while substantially preserving nutrients. Heat-dried powders are the version where losses become a real concern.
Is it better to eat liver once a week or take capsules daily?
Nutritionally they land in a similar monthly range, a few fresh portions' worth. The honest tiebreaker is behaviour: if you'll reliably cook liver weekly, do that and save money. If the weekly liver keeps not happening, daily capsules are the version that does.
Can I take liver capsules and also eat liver?
If you eat liver regularly, you likely don't need capsules that week. The point of the serving size is to keep vitamin A intake sensible. Treat them as substitutes, not stacked.
