Bone Health research - Aquamin
Bone Health research
Bones play many roles in the body including; providing structure, protecting organs, anchoring muscles and storing minerals. While it's important to build strong and healthy bones during childhood and adolescence, it is also essential to maintain bone health during adulthood for wellbeing during ageing and to maintain an active lifestyle.
Bones are continuously changing with new bone being formed and old bone being reabsorbed. Up to the age of 30 the body makes new bone faster than it breaks down old bone, therefore bone mass increases. After that, remodeling continues, but slighty more material is lost than is formed so bone density decreases. Therefore, bones become weaker and more susceptible to fracture.
Aquamin is a marine derived multi-mineral complex which has been demonstrated to possess unique activity in helping to maintain healthy bone formation. This paper is part of a series outlining the science to date and examining the unique effects of Aquamin and the cosequent role that this suite of ingredients can play in addressing common debilitating conditions, such as Osteoporosis, which impede quality of life and put undue strain on overstretched public services.
Osteoporosis is the most common bone disease in humans . The condition degrades bone mass and architecture, and impairs the ability of the skeleton to perform fundamental mechanical functions. Osteoporosis leads to weakening of bone strength and an increase in the risk of fractures. Physiologically, osteoporosis occurs due to an imbalance in bone cell activity by which excessive resorption occurs without adequate new bone formation, thereby reducing total bone mass. As a consequence, bone strength is reduced and leads to increased risk of fractures of the vertebrae, hip or wrist. The disease is more common in Caucasians, women, and older people .
Osteoporosis causes more than 8.9 million fractures annually worldwide, or one every 3 s, approximately half of which occur in Europe, corresponding with one fracture every 8 s. These 4 million osteoporotic fractures are estimated to cost the EU in the region of €31.7 billion, a figure which is expected to increase to €76.7billion in 2050 based on the anticipated changes in the demography of Europe .
A more practical definition of osteoporosis is based on bone mineral density (BMD). Comparison of the BMD with the average BMD of a person of the same gender at age 30 years is used for diagnostics, and the results expressed in standard deviation units, the so-called ‘T-score’. If the T-score is equal to or less than -2.5, osteoporosis maybe diagnosed . The lifetime risk for a wrist, hip or vertebral fracture has been estimated to be in the order of 30% to 40% in developed countries which is similar to that for coronary heart disease. Osteoporosis is not only a major cause of fractures, it also ranks high among diseases that cause people to become bedridden with serious complications. These complications may be life threatening in elderly people . Risk factors for Osteoporosis include previous fracture, family history of fracture, slender habitus, early menopause, treatment with drugs known to affect bone (glucocorticoids) and diseases known to affect bone (rheumatoid arthritis). It is now possible to determine an individual’s risk of osteoporosis and fracture accurately, and to monitor their response to treatment by bone densitome- try. The prediction algorithm FRAXTM allows estimation of 10-year risk and treatment guidance can be based on this. Many cases of osteoporosis are preventable, and treatment is effective in reducing the number of further fractures in patients with established osteoporosis.
Patients at the highest risk for fracture benefit from many licensed treatments. Drugs either inhibit bone resorption or stimulate bone formation. Most drugs approved for use in osteoporosis inhibit bone resorption (e.g. hormone replacement therapy (HRT), bisphosphonates) and usually result in an increase in bone mineral density and a reduction in fracture risk. Osteoporosis can be prevented in people who have osteoporosis but not yet a fracture (primary prevention) and people who have already had a fracture (secondary prevention). These treatments are usually given for secondary prevention and treatment according to the National Institute of Health and Care Excellence guidance. Primary prevention of osteoporosis can be achieved by careful attention to exercise and nutrition .
Public Health Recommendations
The WHO guidance for osteoporosis is that population-based (i.e. public health) prevention programmes are appropriate for all Member States. Global programmes should include attention to nutritional factors, particularly related to adequate intakes of calcium and vitamin D. Cigarette smoking should be avoided, not solely because of its possible effects on skeletal metabolism, but for the many other adverse effects associated with smoking. Preventing excessive alcohol consumption and the avoidance of immobility are also recommended as public health measures .
Due to the morbid consequences of osteoporosis, the prevention of this disease and its associated fractures is considered essential to the maintenance of health, quality of life, and independence . The risk of developing osteoporosis depends on how much bone mass is attained by 30 years of age and how rapidly it is lost after that. The higher the peak bone mass, the less likely the development of osteoporosis is during ageing . However, measures to support bone health are essential to reduce the risk of developing the disease. Calcium and vitamin D intake are the cornerstones in the delay/prevention of osteoporosis . The current International Osteoporosis Foundation recommendation for daily calcium and intake for women aged 19-50 years and men up to 70 years is 1000mg/day. For women 51+ years and men >70 years recommended intake is 1200mg/day . The recommended daily allowance of vitamin D is 600IU/day up to 70 years and 800IU/day >70 years . Calcium 1000 mg/day and vitamin D 800 IU/day given together have been shown to prevent hip fracture in housebound, elderly patients. However other studies have suggested that the current available evidence in fracture prevention by calcium supplementation is weak . This treatment is safe and inexpensive, and does not require monitoring. It is commonly given with other treatments for osteoporosis .
Aquamin and Osteoporosis
The role of Aquamin in bone health is grounded in excellent science demonstrating real effects in increasing bone strength. Aquamin assists in maintaining bone health in a number of ways including;
Providing a bioavailable source of calcium and other essential trace minerals
Enhancement movement / physical activity by reducing symptoms associated with inflammation.
Influencing biochemical bone turnover markers.
Aquamin is a rich source of minerals essential to life and to numerous critical biochemical pathways. Calcium has been associated with a central role in the prevention of osteoporosis and Aquamin provides a unique source with proven benefits for bone health. A recent study by Brennan et al., 2017  in an animal model of osteoporosis demonstrated that supplementation with Aquamin resulted in less deterioration of trabecular bone than calcium carbonate. Trabecular architecture is significantly preserved when using Aquamin as compared to calcium carbonate. This is supported by a preservation of the mineral phase of bone, which is mirrored by the improved material properties of the bone .
Marigot in conjunction with the University of Ulster undertook a large-scale investigation into mineral supplementation and bone health in post-menopausal women . 300 participants in this trial were evaluated over the course of 24 months for changes in bone density and bone turn-over markers. Treatment groups included a placebo group, a group that was treated with Aquamin only and a group that was treated with Aquamin in combination with a short-chain pre-biotic (fructo oligo-saccharide, scFOS). In summary, a reduction in bone mineral density losses over the course of 24 months was reported in women with osteopenia at the outset of the trial who consumed Aquamin in combination with scFOS. Furthermore, a reduction in bone turnover markers was reported in both those women consuming Aquamin only and in those consuming Aquamin plus scFOS. These findings are indicative of a favourable bone health profile in the population most at risk of osteoporosis and its result- ing complications.
Aquamin consumption before and during exercise can offset calcium metabolism disruption associated with exercise in post-menopausal women . Using dampening of serum PTH increases associated with exercise (which will in turn result in bone turnover) as a proxy for calcium absorption, it was demonstrated that Aquamin consumption before and during exercise can reduce exercise-associated calcium metabolic disruption.
Researchers at the University of Michigan have investigated the effects of Aquamin in an in vivo model of bone loss – C67BL/6 mice fed a high-fat western diet (HFWD) over time. Aquamin supplementation prevented bone loss and maintained bone strength in mice fed a HFWD, and even resulted in improved bone structure and function compared to mice in the control group (fed a low-fat “healthy” diet) . Further investigations using this model revealed a 5 – 10 fold increase in strontium levels in the bones of Aquamin-treated mice, highlighting the synergistic benefit achieved in supplementation with a natural multi-mineral complex as opposed to single source mined material . Further evidence that minerals besides calcium are important in Aquamin’s beneficial effects on bone health was described by Bae et al., in 2011  through their use of an ovariectomized (to emulate menopause) rat model. In this work, calcium and magnesium from Aquamin out-performed alternative calcium and magnesium sources with respect to bone density preservation. Using a similar model, it has also been demonstrated that co-adminstration of a probiotic enhanced the performance of Aquamin with respect to bone mineral density .
Investigators at the Royal College of Surgeons, Ireland have demonstrated the ability of Aquamin to improve osteoblast (bone cell) mineralisation both in the absence and in the presence of vitamin D. Using an in vitro osteoblast cell culture technique, those cells cultured in the presence of Aquamin demonstrated a three-fold increase in mineralisation compared to those that were cultured without . Using the same model, it has been demonstrated that addition of vitamin D to the culture medium increased both ALP levels and mineralisation over that observed with Aquamin alone, and vitamin D alone . This work highlights the important relationship between Aquamin and vitamin D, and reinforces the recommendation that Aquamin is consumed along with a diet that is replete in vitamin D. Further support for the role of Aquamin in improving bone growth and osteogenesis was published by the RCSI group in 2015 .
