Supporting bone health and density
    with calcium, phosporus and collagen

For bone health

Calcium Fish Bone (MCHC) Powder Capsules

120 x 650mg

Price $32.50


Why Take This Product

  • Fish bone naturally contains calcium and phosphorus in the right ratio of approximately 2:1 to form hydroxyapatite, which is considered the most bioavailable form of calcium.
  • Naturally occurring high levels of calcium (25.14%), phosphorus (12.75%) and marine collagen (14.2%), are retained. As well as many other naturally occurring minerals and trace elements, including iron, magnesium, selenium, and zinc.
  • Calcium is an essential dietary mineral. It is present mainly in skeleton, which provides structural support for the body. Calcium deficiency is known to lead to osteoporosis, and is very common with an estimated 20% of the worldwide population being calcium deficient.

Key Components


Calcium is an essential dietary mineral. It is present mainly in skeleton, which provides structural support for the body. Calcium is also necessary for muscle contractions, nerve cell signalling, and blood clotting. Calcium deficiency is known to lead to osteoporosis and is very common, with an estimated 20% of the worldwide population being calcium deficient.


Phosphorus is the second most plentiful mineral in your body. The first is calcium. Your body needs phosphorus for many functions, such as filtering waste and repairing tissue and cells. Phosphorus also helps to keep your bones strong and healthy, manage how your body stores and uses energy, and to move your muscles.


When calcium and phosphorus are naturally present in the right ratio of approximately 2:1, they then form a crystalline structure called hydroxyapatite. Calcium hydroxyapatite from fish bone is considered the most bioavailable form of calcium.


Fish collagen is a complex structural protein that helps maintain the strength and flexibility of skin, ligaments, joints, bones, muscles, tendons, blood vessels, gums, eyes, nails and hair. Fish collagen is a Type One collagen, which is the most abundant collagen in the human body. Type One is best known for providing the foundation for beautiful skin, strong connective tissues and sturdy bones. Fish collagen has recently shown its ability to increase the body’s own natural collagen reproduction.
(Refer “Effects of fish collagen peptides on collagen post-translational modifications and mineralization in an osteoblastic culture system”, National Institute of Health September 2013).


Vitamin D3 helps with the absorption of calcium and phosphorus, and helps the calcium to form in the bone matrix.
Vitamin K2 helps to bind calcium to proper places like bone matrix.
Vitamin K2 activates the GLA protein, which inhibits the formation of calcium in arterial walls. Vitamin K2 also activates a protein called osteocalcin that is produced by osteoblast cells. Osteocalcin helps to take calcium from the blood circulation and bind it to the bone matrix. Osteocalcin influences bone mineralization through its ability to bind to the mineral component of bone, hydroxyapatite, which in turn makes the skeleton stronger and less susceptible to fracture.
(Refer “Proper Calcium Use: Vitamin K2 as a Promoter of Bone and Cardiovascular Health” Integrative Medicine February 2015).

    At the beginning of 2017, I required a source of calcium that was going to help preserve my bone density and prevent Osteoporosis.

    I researched the various products around, choosing MCHC as the best source of Calcium.

    I was most impressed with United Fisheries Nutraceuticals Division, who have invested considerable efforts with engaging with Massey University with Lab Studies to prove that their MHCH powder had a positive effect on osteoblast function and inhibited osteoclast activity. Hence not only does the powder encourage new bone matrix that builds bone, but prevents bone breaking down.

    I chose Fish Bone as opposed to Cow Bone because I liked the other composite minerals within fish bone and the unique peptides that allow the human body to better absorb the calcium

    It is essential also for Calcium to end up in the bones and teeth, and thus essential to add Vitamin K2 to ensure the Calcium is delivered to only the Bones and Teeth and not the Arteries. Vitamin D3 ensures a better absorption rate. Both of these components are added to Nutri Zing Calcium Fish Bone Powder. The Vit K2 also being MK-7 form which is a superior longer acting form of K2.

    In July last year, I had a fall, and I fractured my elbow and I was most impressed how the fractured healed well and within the time period the Orthopaedic Specialist indicated. I am sure the MCHC powder helped this process.

    I also had a Dextra Bone Scan in November last year, and was delighted the Endocrinologist summarized that my Bone Density was pretty well preserved and I did not Bisphosphonate Drugs, hence I am of the personal belief the United Fisheries MCHC is effectively helping me.

    I would just like to add as a footnote to above- MCHC powder is very different to taking Calcium in other forms. MCHC is a natural food, and has a natural ratio of 2:1 of Calcium and Phosphorus which is the perfect ratio for humans to absorb and utilize the Calcium.

    I continue to take 4grams of the powder every day and it is the only safest form of Calcium I feel appropriate to take.

    Thank you to Kypros and Smitha for their wonderful help

    To whom it may concern.

    My name is Mrs Campbell

    I have noted the recent report on the ineffectiveness of traditional calcium preventing osteoporosis.

    I started hormone therapy in 2000 at the age of 50 and have continued until the present time. In spite of this the bone density scans that I had in 2003, 2008 and 2012 showed that my bone density has decreased each year. In May of 2014 I began taking (United) Calcium Fish Bone (MCHC) Powder. The scan that I had in October 2015 showed a reversal of this trend and an increase in bone density.

    Given that nothing else has changed in my diet, exercise regime or hormone treatment over the past 2 years, I feel that i can attribute these results to the fish bone calcium that I take and believe that the calcium found in fish bone powder is an effective source of calcium and can offer help to people suffering from decreasing bone density and the problems that that can cause.

2014 Research Conducted By Massey University

Bone tissue grows, repairs and degenerates through the activity of two main types of cells. Bone is broken down by osteoclasts and then replaced through the formation of new bone by osteoblasts. An imbalance between bone breaking down and bone formation results in a decrease in bone mineralisation, this leads to osteoporosis.
Research conducted by Massey University tested the effect of United Fisheries fish bone MCHC powder on osteoblast cell proliferation and osteoclast formation. United Fisheries fish bone MCHC powder had a significant effect on bone cells in the lab, indicating potential positive effects on bone cell function. The studies showed that United Fisheries fish bone MCHC powder enhanced the growth of osteoblasts and stimulated them to produce more bone mineral, while reducing and inhibiting the formation of osteoclasts.
