MOFO Male Optimization Grass-Fed Organ Complex, 180 Caps

What this is

MOFO is a desiccated beef organ supplement from Ancestral Supplements, sold as a bottle of 180 gelatin capsules at 410 mg each. The front of the bottle carries the line "Brad Kearns' MOFO — Male Optimization Formula w/ Organs" and describes the contents as 100% grass-fed and grass-finished, with absolutely no fillers or flow agents. Five bovine organs make up the formula: testicle, prostate, heart, liver and bone marrow, each sourced in New Zealand.

Organ supplements are a food-based category rather than an extract-based one. Instead of isolating a single compound and standardising it to a percentage, the whole organ is dried and milled, then put into a capsule. That is the entire approach here, and it is why the panel lists organs by name and weight rather than listing vitamins or a proprietary herbal blend. You can browse the rest of our Supplements for Men range for formulas built on other principles.

What's inside

The serving is six capsules, and those six capsules carry 2,460 mg of organ material in total. Here is what each component actually is.

• New Zealand grass-fed testicle (bovine) — 1,260 mg. This is the single largest component, making up a little over half the serving by weight. It is the ingredient the formula is built around, and the reason the product is positioned for men rather than as a general organ blend.
• New Zealand grass-fed prostate (bovine) — 300 mg. A small glandular organ, included here as a whole-organ powder alongside the other four.
• New Zealand grass-fed heart (bovine) — 300 mg. Heart is a muscular organ and one of the more widely eaten offal cuts worldwide — grilled, braised or stuffed in cuisines from Peru to Japan.
• New Zealand grass-fed liver (bovine) — 300 mg. Beef liver is the most commonly eaten organ meat in Western cooking and the one most people have encountered as a food. The NIH Office of Dietary Supplements consumer overview gives general background on how dietary supplements of all kinds are regulated and labelled.
• New Zealand grass-fed bone marrow — 300 mg. Marrow is the soft tissue inside the long bones, long used in traditional cooking for broths and roasted marrow bones. It is the only one of the five that the panel does not annotate with "(bovine)".

The panel marks every one of these five amounts with a double asterisk and states "Daily Value not established" — meaning no reference intake has been set for them, so no percentage can be listed. That is a normal and honest way to label a food-based ingredient, and it is worth understanding rather than skipping past; the NIH Dietary Supplement Label Database is a useful place to see how other products present the same kind of panel.

Grass-fed and grass-finished is a more specific description than grass-fed alone. Grass-fed describes what the animal ate for part of its life; grass-finished means it stayed on pasture through to the end rather than being moved onto grain. New Zealand is a common source for this because its cattle are pasture-raised year-round as a matter of normal farming practice.

The only other ingredient on the panel is gelatin, which forms the capsule shell itself. There is nothing else — no magnesium stearate, no silica, no rice flour. The front label states this directly as "absolutely no fillers (or) flow agents."

How to take it

The label's suggested use is six capsules daily, or as directed by a healthcare professional. That is the only dosing instruction printed on the bottle — there is no loading phase, no cycling schedule and no timing window given, so there is nothing to follow beyond the daily serving. At six capsules a day, a 180-capsule bottle covers 30 servings.

The capsules are a standard opaque gelatin shell and can be taken with water. The bottle gives no instruction to take them with food or on an empty stomach. Store the closed bottle somewhere cool and dry and keep the cap tight; a dried organ powder is best kept away from heat and humidity.

Who it's for

This is an adult product for men who already know they want a whole-food organ supplement and want one with a defined, published breakdown rather than an unnamed blend. The nose-to-tail and ancestral-eating audience is the obvious fit — people who have come across desiccated organ capsules through carnivore or whole-food diet reading and want to see exactly which organs, and how many milligrams of each, they are getting.

It will suit you less well if you want a herbal formula, a vitamin-and-mineral stack, or anything vegetarian. The capsule shell is gelatin and the contents are entirely animal-derived, so it is neither vegan nor vegetarian, and six capsules a day is a meaningful commitment if swallowing capsules is something you find difficult. Our wider Supplements category has plant-based and vitamin-based alternatives.

Good to know

This is a dietary supplement for adults 18 and over, not a medicine, and nothing on the label states otherwise — the bottle itself carries the standard FDA disclaimer. If you take prescription medication, have a diagnosed medical condition, or are pregnant or breastfeeding, speak to a licensed healthcare professional before starting it. The same goes if you have any allergy or sensitivity to beef or to gelatin, since every ingredient here is bovine.

The bottle is manufactured in the USA for Ancestral Supplements, LLC of Willis, Texas, and the side panel notes the product is made "one small batch at a time." For general reading on how to think about supplement safety and quality, the NCCIH overview of dietary and herbal supplements and the FDA's questions and answers on dietary supplements are both worth a few minutes. Neither source refers to this product; they are background on the category.

Keep out of reach of children, and keep the bottle closed between servings.

Frequently Asked Questions

How many capsules are in the bottle, and what counts as one serving?

The bottle holds 180 capsules and one serving is six capsules, which works out to 30 servings per bottle. Each capsule is 410 mg, so a full six-capsule serving delivers 2,460 mg of organ material.

Are these capsules suitable for vegetarians or vegans?

No. Both the contents and the capsule itself are animal-derived — the five ingredients are bovine organs and the only other ingredient listed is gelatin, which forms the capsule shell.

Where do the organs come from?

All five organs are sourced from New Zealand cattle, and the panel names New Zealand explicitly on each line. The front label describes the animals as 100% grass-fed and grass-finished, meaning they were raised on pasture through to the end rather than being moved onto grain.

Does it contain fillers, binders or flow agents?

No. The front label states "absolutely no fillers (or) flow agents," and the panel backs this up: the only entry under Other Ingredients is the gelatin capsule shell.
