What is OsteoThera Plus Ipriflavone?

OsteoThera Plus Ipriflavone is a vitamin and mineral supplement formulated to support bone health with a more comprehensive formula than calcium alone. Easy-to-absorb calcium citrate-malate is combined with other minerals important for bone health, including magnesium and boron. Vitamins D and K are included to further assist calcium utilization and promote normal bone formation. Ipriflavone, an isoflavone-derived compound, provides additional benefits for bone density.

Why is Ipriflavone added to this bone support supplement?

Ipriflavone is a derivative of naturally occurring isoflavones found in soy. Numerous published clinical trials have demonstrated the efficacy of this flavonoid-like compound in supporting healthy bone mineral density and metabolism. OsteoThera Plus Ipriflavone provides 300 mg of Ipriflavone in each serving, the same amount used in clinical studies.

Why is calcium citrate-malate used as the form of calcium in OsteoThera Plus Ipriflavone?

Calcium citrate-malate is significantly more absorbable compared to other forms of calcium, such as calcium carbonate. About 40% more calcium is absorbed from calcium citrate-malate compared to calcium carbonate or milk. Calcium citrate-malate is also well-tolerated. It does not produce intestinal discomfort, constipation, or gas like some forms of calcium.

How do the other minerals and vitamins in OsteoThera Plus Ipriflavone support bone health?

Proper calcium utilization is crucial to maintain and support normal bone density. Increasing age, sex, race, diet choices, and exercise frequency are all factors that can negatively affect bone health. Magnesium and boron are also necessary for healthy bones. Magnesium supports bone strength and remodeling, while boron promotes calcium and magnesium balance. Vitamin D is essential for calcium absorption and supporting healthy bone mineral density. Vitamin K activates proteins used in bone metabolism. The combined actions of these nutrients create a more comprehensive approach to maintaining bone health.

Why are 3 forms of vitamin K included?

Several different forms of vitamin K exist, with the primary dietary form being vitamin K1, or phylloquinone, found primarily in green vegetables. Another form of vitamin K known as vitamin K2, or menaquinone, is found in animal products such as meat or eggs, as well as in foods such as cheese and natto, a fermented soy product.

While most of the benefits of vitamin K were previously attributed to vitamin K1, recent research has identified important benefits for vitamin K2. For optimal bone health, this product provides vitamin K1 and vitamin K2 as menaquinone-4 (MK-4) and menaquinone-7 (MK-7).

How much OsteoThera Plus Ipriflavone should I take?

Suggested use for this product is 2 tablets twice daily with food or as directed by a healthcare professional. This dose supplies 500 mg of calcium and 200 mg of magnesium, or 50% of the RDA for each of these minerals.
