Skeletal Strength is designed to nutritionally support the skeletal system and help maintain healthy bones and structural integrity. Skeletal Strength contains vitamins, minerals and herbs that have been shown to promote bone mineralization and inhibit bone loss. Skeletal Strength also provides digestive aids to ensure absorption of nutrients that are vital for bone health. Skeletal Strength contains:

Vitamin A is an essential nutrient that maintains healthy vision, provides antioxidant protection and immune system support, and plays a crucial role in bone formation. 14

Vitamin C is essential for human life because the body cannot create it, nor does it store it. Vitamin C deficiency is associated with low bone mass and an elevated risk of bone fracture. 13, 5, 6

Vitamin D3 regulates calcium absorption and bone metabolism. Vitamin D promotes intestinal absorption of calcium and phosphorous and plays a central role in maintaining calcium homeostasis and skeletal integrity. Low blood levels of vitamin D are associated with reduced bone mineral density and are common in women with osteoporosis. 7-10

Vitamin B6 Research suggests that vitamin B6 deficiency may have detrimental effects on bone collagen and thus contribute to impaired bone quality. 11, 12

Vitamin B12 Research indicates that vitamin B12 deficiency, a common health problem among older persons and vegetarians, is associated with increased bone turnover and bone fractures. Increasing vitamin B12 levels has been shown to provide a modest decrease in fracture risk.1316

Calcium is the most plentiful mineral in the body, with about 99% stored in bones and teeth. The importance of calcium for skeletal integrity is well known. Sufficient intake of calcium, together with vitamin D, is recommended for the prevention and treatment of osteoporosis. 2, 3, 9, 17-19

Iron Adequate iron intake is necessary for the healthy development of blood, soft tissue and bones. Recent research has shown that iron deficiency inhibits the activity of human osteoblasts (bone building cells) in vitro. Animal research has also confirmed that iron deficiency anemia demonstrates a significant impact on bone, negatively affecting bone mineralization and increasing bone loss. 2, 3, 9, 20, 21

Phosphorus, the second most abundant mineral in the body following calcium, is primarily stored in the bone and is essential for bone health. Phosphorus regulates bone formation and inhibits bone resorption (bone loss); thus, phosphorus deficiency can impair bone health. 22-25

Magnesium is an essential component in the formation of bone and protein, with nearly 70% of the body’s supply of magnesium found in the bones. Adequate magnesium intake is necessary for bone cell activity and skeletal integrity, as magnesium status is related to whole body bone density. Epidemiologic studies have shown that magnesium deficiency accelerates bone turnover and is a risk factor for osteoporosis. 1, 2, 9, 26-30

Zinc is necessary for optimal development of bone matrix and sustaining bone density. The bone matrix is a collagen based foundation on which bones are built, which promotes bone strength and resistance to fractures. Zinc has been shown to stimulate the activity of osteoblasts and inhibit bone resorption, thus suggesting its therapeutic value in the prevention of osteoporosis. 3, 9, 31-34

Copper is a trace mineral needed to build elastin and collagen—important components of bone and connective tissue. Copper may help protect against bone loss and the development of osteoporosis, as subclinical copper deficiency appears to be a contributing factor to bone loss in the elderly. 2, 3, 9, 31, 35, 36

Manganese, a trace mineral found primarily in the bones, plays a role in the synthesis and repair of connective tissue and bones. Manganese deficiency has been shown to disrupt the action of enzymes and hormones involved in bone metabolism and appears to be associated with decreases in bone mass. 2, 3, 31, 37-39

Potassium plays a role in bone health through its ability to neutralize bone depleting metabolic acids and reduce urinary calcium loss. Current evidence from a variety of observational, clinical and intervention studies suggests a positive association between a potassium rich diet and skeletal health and osteoporosis prevention, particularly among the elderly. 13, 40-43

Boron, a trace mineral, participates in calcium metabolism and bone growth and maintenance. Animal studies have confirmed that boron intake has a positive effect on bone strength and bone mineral composition. 44-46

Horsetail is a rich source of calcium and other bone building minerals, including iron, magnesium, manganese, phosphorous, potassium, silica and zinc. As a result, horsetail is often used to help strengthen the skeletal system and facilitate the healing of broken bones and damaged connective tissue. Recent in vitro studies suggest that horsetail can inhibit the formation of osteoclasts (cells that break down bone tissue). 47-51

Betaine HCl facilitates the digestion of protein and may also enhance the absorption of calcium. Research suggests that insufficient stomach acidity can lead to malabsorption of dietary calcium and impaired bone health. 52-55

Papaya contains enzymes that break down protein, fats, carbohydrates, and even milk protein. In addition, papaya is a rich source of vitamin C and potassium, and has been shown to enhance the absorption of iron in food. 47, 52, 56

Parsley contains many vitamins and minerals, including calcium and iron. Animal studies suggest that parsley may help inhibit bone resorption. 47, 48, 57

Pineapple is a natural source of bromelain, a protein digesting enzyme that may also be beneficial in the treatment of osteoarthritis. Pineapple contains significant amounts of vitamins A and C, and has been shown to have a mild to moderate enhancing effect on the absorption of iron in food. 47, 49, 52, 56, 58

Valerian is regarded as an effective antispasmodic (muscle relaxant), mild analgesic (pain reliever) and sedative. Valerian is commonly used for anxiety and stress related conditions, insomnia, migraine/tension headaches, intestinal spasms and muscle cramps. Valerian is also a rich source of calcium and magnesium. 47, 48, 59-61

Licorice contains a natural flavonoid that have been shown to suppress the formation of osteoclasts and prevent inflammatory bone loss in mice. Another licorice flavonoid, glabridin, has been shown to inhibit osteoclast formation, as well as prevent damage to osteoblasts. 62-65
