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).

    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.
    Mrs Campbell


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.
