What it is
Peak Performance Grass Fed Bone Marrow is a bovine whole bone extract dietary supplement sold as a 180-capsule bottle. One serving is six capsules and supplies 3 g of grass fed whole bone extract, which the Supplement Facts panel breaks out into three named fractions: bone matrix, bone marrow and cartilage. The capsule shell is gelatin and water, and there is nothing else in the formula. You will find it in our men's supplements category, alongside the rest of the capsule range.
At six capsules per serving the bottle holds 30 servings, which works out to a 30-day supply at the suggested usage on the label.
What's inside
The whole ingredient list is one active plus a capsule, so it is worth spending a moment on what each part actually is.
Grass fed whole bone extract (bovine). "Whole bone" is the distinction this product is built on. A marrow-only supplement uses the soft tissue from inside the shaft of the bone; a whole bone extract takes the bone as a unit. The label names the three parts that unit contains. Bone matrix is the bone itself — the mineral and protein scaffold that gives a bone its rigidity. Bone marrow is the soft, fatty tissue held inside it, the part a chef scoops out of a roasted marrow bone and spreads on toast. Cartilage is the smooth, rubbery tissue capping the ends of the bone where it meets the next one — the gristle you hit at the end of a chop.
None of this is exotic eating. Marrow bones are the backbone of stock and broth in more or less every cuisine that has ever had a stockpot: osso buco is built around a cross-cut veal shank precisely so the marrow is still in it, caldo de res and pho both start from beef bones, and roasted marrow served with bread and parsley salad is a restaurant standard. Cartilage does the same job in a long-simmered stock, which is where the body of a good broth comes from. What a capsule changes is the format, not the food.
"Grass fed" describes what the cattle ate. It is a statement about the animals the material came from, not about the chemistry of what is in the bottle.
The side panel of the bottle also states that the extract is freeze dried. Freeze drying removes water by sublimation — the frozen material is held under vacuum so its ice passes straight to vapor without melting — which is why it is used in place of heat drying. The same panel names collagen among what the extract contains, which is consistent with the raw material, since collagen is the main structural protein in bone matrix and cartilage.
Gelatin and water are listed as the other ingredients. That is the capsule shell rather than a second active, and gelatin is itself made from collagen — so on this product the shell and the contents come from broadly the same kind of source.
For general background on how dietary supplements are labeled and regulated, the NIH Office of Dietary Supplements consumer overview and the NCCIH page on supplement safety are useful starting points. Neither page refers to this product.

The panel carries no %DV column of its own: every row is marked "Daily Value (DV) not established," which is the standard notation for an ingredient that has no established Daily Value. The three fractions sit as indented lines beneath the single 3 g figure, so the split between them is not declared and this listing does not estimate it. The FDA's page on structure/function claims explains the asterisk convention you will see on the bottle's side panel.
How to use it
The label's suggested usage is six capsules daily, or as recommended by your healthcare practitioner. That is the whole of the printed direction.
Storage is straightforward: the panel says to store in a cool, dry place after opening.
Who it's for
This is a product for adults who already know they want an animal-sourced bone supplement and want the whole bone rather than marrow on its own. The six-capsule serving is worth knowing about before you buy: it is more capsules per day than most supplements ask for, and it is why a 180-count bottle is a 30-day supply. If swallowing six capsules in a day is not something you want to do, this format is not a good fit.
It is also worth being clear about who it is not for. The active ingredient is bovine and the capsule is gelatin, so the product is neither vegetarian nor vegan, and anyone avoiding beef for dietary or religious reasons should skip it. The label's caution line restricts it to adults. You can compare it against the rest of our supplements range before deciding.
Good to know
The Supplement Facts panel prints a caution in full: "For adults only. Consult a physician if you are pregnant/ nursing, taking medication or have a medical condition. Keep out of reach of children." That is the label's own wording and it is the one to follow.
On allergens, the panel states the product is "NOT manufactured with wheat, gluten, milk, egg, fish, shellfish or tree nut ingredients," and the side panel adds that it is free of gluten, GMOs, additives, preservatives, artificial colors, pesticides, soy and dairy. Three roundels are printed beside the distributor block: a GMP mark, a "Formulated in the USA" mark and a "Non GMO" mark.
The distributor is named on the panel as Peak Performance Life LLC, Henderson, NV 89052. If you are on prescription medication or managing a health condition, the NIH Dietary Supplement Label Database is a neutral place to compare label panels before you talk to a pharmacist; it is a public reference and says nothing about this product.
Frequently Asked Questions
How many capsules are in a serving, and how long does one bottle last?
Six capsules make one serving, and the 180-capsule bottle holds 30 of them — a 30-day supply at the label's suggested usage. That is more capsules per day than most supplements ask for, so it is the single figure worth checking before you order.
Is this suitable for vegetarians or vegans?
No. The active ingredient is a bovine whole bone extract and the capsule shell is gelatin, which is also animal-derived, so the product is unsuitable on both counts.
What is the difference between bone marrow and whole bone extract?
Whole bone extract is the broader of the two. A marrow product uses only the soft tissue from inside the bone, whereas this label declares bone matrix, bone marrow and cartilage together under a single grass fed whole bone extract line.
Does the label say how much of each fraction is in a serving?
No. The panel gives one combined figure — 3 g of grass fed whole bone extract per six-capsule serving — and lists bone matrix, bone marrow and cartilage beneath it without individual amounts, so this listing does not break the 3 g down.
