The invention discloses health-care food for improving
bone density and a preparation method thereof. According to the weight of 0.4g of contents in each grain, 1000 grains of capsules are prepared, and each component and the dosage are as follows: 100-200g of functional
red yeast rice, 87-200g of milk mineral salt, 3-14g of
zinc gluconate, 40-120g of
magnesium carbonate, 0.2-0.6g of cupric sulphate, and 0.2-0.6g of
vitamin D3. The preparation method comprises the following steps: respectively screening the functional
red yeast rice, the milk mineral salt, the
zinc gluconate, the
magnesium carbonate, the cupric sulphate, the
vitamin D3 and auxiliary materials through an 80-mesh
sieve, mixing the materials according to a compounding ratio,
pelletizing the mixture,
drying granules, trimming granules, generally mixing the granule, and then loading the granules into hollow capsules to obtain the health-care food. The health-care food for improving the
bone density, disclosed by the invention, solves the problems that
calcium loss cannot be restrained by simply enriching the
calcium, the
calcium utilization rate is low, even hypercalcemia is initiated and the like, and avoids the limitation of the application of similar
estrogen components. The health-care food can promote the absorption of the calcium and can improve the deposition of skeleton calcium salt, so that the calcium
utilization rate is improved.
