The Facts:

According to research on Ancestral People and the dietary habits of traditional populations around the world, bone marrow was one of the most valuable food sources - when it could be acquired. Some evidence even suggests that the fat-rich, nutrient-dense marrow was the first animal food early hominids learned to scavenge, and this is what prompted rapid brain development - prior to hunting. With remnants of “cracked open bones” and “piles of finely broken bone chips” from the Native Indians of the North, and “an emphasis on percussion-based scavenging of inside-bone nutrients” from our 2 million year old ancestor - H. habilis.

The Need:

Modern diets have not only forgotten this ancient wisdom on the importance of bone marrow, but they’ve become deficient in the unique nutrients this superfood provides. Leading to imbalances in critical vitamins and minerals – like vitamin k2 and calcium – deficiencies in essential fats and proteins – like conjugated lineolic acid (CLA) and glycine – and a lack of protection/support from the beneficial compounds specific to bone marrow – like alkyglycerols (AKG) and stem cells. And having an impact on everything from immune health and blood cell production, to bone strength and tissue repair, to inflammation and cellular damage.

The Solution:

Fortunately, benefitting from the unique components of bone marrow doesn’t require the savage behavior of wolves - who fight over deer carcass bones with the highest marrow yields – or vultures – who drop femurs from the sky after sucking out all the marrow. But it does require tapping into the same primal instincts of our ancestors, and prioritizing this disease-preventing, cell-supporting, immune boosting food. With our PrimalRx supplement providing a pure, unblended marrow, that supplies far more K2 (as MK-4), CLA, AKG and glycine-rich collagen than you could ever acquire from bone broth. And packing an unmatched level of ruminant quality - similar to what was found historically.

Suggested Use: 

Adults take 3 capsules per day with food

Good for the Health Benefits

"It is well know that Bone Marrow is very healthy for you, but it can be hard to find and for some not that tasty. In comes this product, which features bone marrow from grass-fed / pasture raised cows, which translates in to a much healthier end product. Taking these, a couple of normal sized capsules, I had no issues swallowing them and no side effects. I know I am healthier for taking these, would recommend that you try it."

Easy way to intake bone marrow

"When ordering supplements or vitamins and such I am always worried as to what I will get, what the quality will be, and about how my system will tolerate them. This seems to be a very good product. It is packaged well and arrives without damage or spillage in shipping. After just a few days there are no negative effects. All seems as it should if you are looking for an easy to take bone marrow capsule, consider trying this one."

-Brian H...

Convenient and Clean Supplements

"Despite the small bottle, I took three capsules of these bovine marrow supplements from PRIMALRX a day, as suggested. There are actually fewer capsules to take than some other brands on the market for the same amount of bovine marrow. I still love preparing bone soup, but it takes a lot of time and effort, so this is the closest I can go to having good bones, joints, skin, hair, and general health."

-Sunny224

No Added Junk - Just The Marrow And Capsules

"For many years, I have regularly taken several various glandular supplements, but have never tried marrow before and am curious to see its benefits. This is an impressive product... no fillers... no flow agents... no preservatives. You get the marrow and the capsule... nothing else. The quality of this supplement is good... sourced from clean New Zealand raised cattle. For a 30-day supply, this seems fairly priced."
