Strontium Bone Maker 340mg - A Valuable New Partner For Calcium, 60 vcaps , (Doctor's Best)
Strontium is found naturally in the human skeleton. The level of strontium in bone tissue is approximately 3.5% of the calcium content of bone. Strontium taken orally through the diet and from supplements is preferentially incorporated into the teeth and bones. Research suggests that the oral absorption of strontium is dependent on age and decreases with increasing age. Scientist have suggested two methods of absorption of strontium from the gastrointestinal tract: passive diffusion and carrier-mediated absorption. In adults, strontium is absorbed to a lesser extent than calcium, possibly due to the larger molecular size of strontium in comparison to the calcium molecule. Both calcium and strontium compete with one another for absorption in the intestines. High dietary intake of calcium has been shown to reduce concurrent absorption of strontium. It has been proposed that when both elements are present together, twice the amount of calcium is absorbed from the intestines in comparison with strontium.- Science-based nutrition
- Dietary supplement
- Helps maintain strong, healthy bones.
Strontium is a naturally occurring mineral present in water and food. Trace amounts of strontium are found in the human skeletol. Strontium has an affinity for bone and is taken up at the bone matrix crystal surface. The influence of stronium on bone metabolism has been researched since the 1950's. Studies show that strontium positively affects bone metabolism to promote bone formation and decrease bone resorption, leading to normalized bone density. Strontium citrate is a naturally occuring compound supplying stable strontium that is safe and suitable for consumption as a dietary supplement. (This form strontium is entirely different from the radioactive and unstable "strontium-90" formed by nuclear fission.)
The role of stable strontium in human bone
Animal studies suggest that extremely high dietary intakes of strontium, in the absence of adequate calcium intake, can actually disturb bone mineralization. At such concentration levels strontium replaces calcium ions in bone. The unbalanced incorporation of strontium into the bone tissue in the place of calcium may cause a disturbance of the bone lattice, resulting in deceased bone mineral density. It is precisely for this reason that calcium intake must be adequate when supplementing with strontium.
Futher studies in animals reveal that strontium given as a part of the normal diet (when calcium intake is adequate) may have profound effects on bone formation and density. Oral administration of strontium doses to rats was shown to ehnace the rate of bone formation and trabecular bone density.
Benefits
Helps maintain strong, healthy bones.

RESEARCH DATA
Mechanism of Action
Strontium is a bone-seeking mineral incorporated by ionic substitution for calcium onto the crystal surface of bone. Researchers have looked at the therapeutic potential of strontium based on in vitro, animal and human studies. After assessing and analyzing the results of several investigations, scientists theorize that strontium may benefit bone health via a two-pronged effect. It appears that strontium interacts with the cells responsible for the normal bone remodeling process. The cells responsible for bone formation are know as osteoblasts, and the cells responsible for bone breakdown, or resorption, are called the osteoclasts. Strontium may stimulate the replication of pre-osteoblasts, leading to an increased proliferation of osteoblasts (cells that build bone). This causes an increased synthesis of bone matrix. In terms of effects on osteoclasts (cells responsible for bone resorption), in vitro work shows that strontium directly inhibits their activity and prevents bone breakdown.
Animal Studies
Animal studies have shown that supplementation with strontium is extremely beneficial as a bone building catalyst. In one such study, strontium administered at low doses has been shown to increase the number of bone forming sites in thighbones of adult rats, without adverse effects on the mineral content of bone or mineralization of the organic bone matrix. A second study in rats indicated that strontium could reverse bone loss associated with a deficiency of the hormone estrogen in females.
Clinical Trials
Multiple clinical studies utilizing different forms of strontium have been conducted since the 1950s. Stable strontium as gluconate, carbonate, lactate and chloride have all been used in various trials that have reported efficacy of supplemental strontium in promoting healthy bones. Regardless of the form, it is the elemental strontium itself that exerts the positive effect on bone. While all of the various forms have a bioavailability of between 25 and 30%, gastric tolerance is reportedly better with strontium citrate, the form used in Strontium BoneMaker.
SUGGESTED USAGE
Take two capsules at the same time daily with or without food. Be sure to take at least the RDI of calcium and vitamin D3. Do not take this product at the same time as a calcium supplement, as these minerals may compete with each other for absorption.
Best way to take your strontium is in the morning on an empty stomach as you will digest it quickly and you can then after one hour have your breakfast and take all your vitamins. Take the two caps at the same time. If you cannot swallow capsules please open capsule and put into apple sauce but not into any dairy products as the calcium in it will compete with the Strontium Bone Maker's absorption.
Note: Individuals with a severe renal impairment should check with a healthcare practitioner before using this product.
Does Not Contain: milk, egg, wheat, corn, sugar, sweeteners, starch, salt, or preservatives.

FAQ
I take your High Absorption Calcium. Do I really need Strontium Bone Maker, too? Why?
You may benefit more by also taking Strontium Bone Maker. Studies in postmenopausal women diagnosed with osteoporosis showed a strong benefit in women taking strontium and calcium/Vitamin D versus women taking calcium/Vitamin D and a placebo.
In one such study of 1,442 women, the strontium group had significant increases in bone mineral density and a decreased lumbar fracture risk by 41% compared to those given calcium/vitamin D plus placebo. If you decide to take strontium, it should be taken at a different time of day than the High Absorption Calcium.
It is also extremely important that adequate calcium and vitamin D is taken, as strontium can compete with calcium uptake into bone. Some animal research has shown that strontium may actually demineralize bone when calcium is deficient in the diet.
