Male Optimization Formula Organs MOFO Ancestral Supplements

What this is

MOFO is a bovine organ supplement from Ancestral Supplements, sold as a bottle of 180 gelatin capsules at 410 mg each. The front of the bottle spells the name out in full — Male Optimization Formula w/ Organs — and the Supplement Facts panel sets a serving at six capsules, which makes the bottle 30 servings. Five organs are listed, all of them New Zealand grassfed bovine: testicle, prostate, heart, liver and bone marrow. There is no botanical extract in it, no vitamin premix and no proprietary blend — the panel names and weighs each organ separately.

Two lines printed on the front describe how the product is made rather than what it is supposed to do: “100% Grass-Fed & Grass-Finished” and “Absolutely No Fillers (or) Flow Agents”. The panel records that the bottle is manufactured in the USA for Ancestral Supplements, LLC of Willis, Texas, and it closes with the company's own line, “one small batch at a time”. If you want general background on how dietary supplements are labeled and regulated in the United States, the NIH Office of Dietary Supplements publishes a consumer overview of dietary supplements — that page is general reading and does not refer to this product.

The five organs on the panel

Every active ingredient in MOFO is an organ from grass-fed New Zealand cattle, and the panel weighs each one separately per six-capsule serving. Organ meats have been ordinary food for most of human history and most of them still have a place on a menu somewhere, so it is worth knowing what each of these actually is.

• Testicle — 1,260 mg. More than half the serving by weight, and by far the largest single ingredient on the panel. As food, beef testicle appears as criadillas in Spain and Argentina and as “Rocky Mountain oysters” across the American West, where it is typically sliced thin, floured and fried. In capsule form it is an uncommon ingredient, and its share of the serving here is what sets the shape of this formula.
• Prostate — 300 mg. Rarely eaten anywhere as a named dish, and rarely offered on its own as a supplement ingredient.
• Heart — 300 mg. Heart is a working muscle rather than a soft organ, which is why it eats more like steak than like liver. It is grilled on skewers as anticuchos in Peru and stuffed and roasted across central Europe.
• Liver — 300 mg. The best-known offal in the Western kitchen: liver and onions, coarse country pâté, braunschweiger, and the base of a classic terrine. Liver has a strong, distinctly mineral flavor, which is a large part of why capsules exist at all.
• Bone marrow — 300 mg. The soft tissue from inside the bone, served roasted in split marrow bones with toast in a good many restaurants and spooned out of the shank in osso buco. On the label it is the one line that does not carry the “(Bovine)” suffix.

The five figures add up to 2,460 mg per serving, and 2,460 divided across six capsules is 410 mg each — exactly the per-capsule figure printed on the front of the bottle. The panel and the front label agree with each other.

No fillers or flow agents, the other line on the front, is a manufacturing statement rather than a benefit. Flow agents — magnesium stearate and silicon dioxide are the usual ones — are processing aids that stop powder from clumping so it moves cleanly through an encapsulating machine. Leaving them out makes filling slower and fussier.

Supplement Facts

The double-asterisk footnote is standard labeling, and the FAQ below explains what it means. The FDA answers questions of that kind in its questions and answers on dietary supplements, and the NIH keeps a searchable Dietary Supplement Label Database if you like comparing panels side by side. Neither source refers to this product.

How to take it

The label's Suggested Use is six capsules daily, or as directed by a healthcare professional. That is the entire printed instruction — the panel gives no time of day, no with-food or without-food note, and no cycling schedule. Six capsules a day against a 180-capsule bottle works out to a 30-day supply.

Six capsules is a high daily count by supplement standards and it is worth knowing that before you buy. There is no smaller serving printed on this label, so anyone who wants to start lower should raise it with their own healthcare professional rather than work from a figure found online.

Who it suits

MOFO is for adults 18 and over who are already interested in whole-animal, nose-to-tail eating and would rather take organ meats in a capsule than cook them. Liver is an acquired taste, testicle and prostate are not sold at most butchers, and bone marrow needs an oven and an hour of attention — a capsule sidesteps all of that. If you are browsing the wider men's supplement category on this store, this is one of the few items in it built from animal ingredients rather than a botanical blend.

It is equally worth saying who it is not for. Every active ingredient is bovine and the capsule shell is gelatin, so MOFO is not vegetarian, not vegan, and not suitable for anyone avoiding beef on religious or dietary grounds.

Good to know

• Keep the bottle out of reach of children.
• Talk to a licensed healthcare professional before starting this or any supplement, particularly if you have a medical condition or take prescription medication.
• Anyone with a beef allergy or sensitivity should avoid it, shell included.
• Nothing but the gelatin capsule appears on the Other Ingredients line — no color, no sweetener, no flavoring.
• The NCCIH publishes general safety guidance on dietary and herbal supplements, worth reading once if supplements are new to you. It does not refer to this product.

Frequently Asked Questions

How many capsules are in the bottle, and how many servings is that?

The bottle holds 180 capsules and the label sets a serving at six capsules, which gives 30 servings. At the Suggested Use of six capsules daily that is a 30-day supply.

Is MOFO suitable for vegetarians or vegans?

No. Every ingredient on the panel is bovine, including the gelatin the capsule shell is made from, so the product is neither vegetarian nor vegan. It also is not suitable for anyone avoiding beef for religious or other dietary reasons.

What does “Daily Value not established” mean next to each ingredient?

It means the FDA has not set a reference intake for that ingredient, so there is no percentage to print. Daily Values exist for specific named nutrients such as vitamin C or calcium; whole-organ ingredients are not single nutrients, so the panel carries the double-asterisk footnote instead of a %DV column. It is a normal labeling outcome and appears on most organ supplement panels.

What is the difference between grass-fed and grass-finished?

Grass-fed describes the animal's diet and grass-finished describes the last stage of it. An animal can be raised on pasture and then moved onto grain for its final months and still be called grass-fed, so the second word is the one that rules that out. This label prints both, along with New Zealand as the source country for the organs — a climate that lets cattle graze outdoors year-round, which is why so much pasture-raised beef sourcing points there.

How is the order packaged?

Orders ship in a plain outer box. It will not show the Gear Isle name.
