The human skeleton works as a scaffolding for the body, maintaining its shape, protecting vital organs and acting as a latching structure for muscles.

4PLUSNUTRITION offers the possibility of giving it its necessary support, exploiting the certified quality of the raw materials used in BONE+: calcium, phosphorus, magnesium, vitamin K and vitamin D.
The synergy between calcium, phosphorus, magnesium, vitamin D and vitamin K allows maximum absorption of all the BONE+ components as well as the desired bone mineralization.

The vital and best known element for the health of bones is calcium. Together with other elements such as phosphorus and magnesium, this is responsible for the formation of the bone, tooth and nail structure. The correct absorption of calcium is strictly connected with the presence of phosphorus, magnesium, vitamin K and vitamin D. These are elements that co-operate in numerous functions and depend on each other.

85% of the phosphorus present in the human skeleton is in the form of tricalcium phosphate. The increase of the phosphate concentration in the blood promotes the deposit of calcium on the bones, while the concentration of phosphorus in the blood is connected to the absorption of vitamin D.

To carry out its function, vitamin D requires magnesium. The same magnesium helps better absorb calcium, phosphorus and potassium that work together for a correct cardiovascular function.

With magnesium, vitamin D helps absorbing calcium. This is used in fixing the right quantity of calcium in the internal organs, urinary tract and arteries, eliminating any excesses that can create imbalance and an increase in the risk of hypertension, spasms and gallstones.

Present in BONE+ is also vitamin K, with its increased dose of 180mcg, approved only by the latest regulations. Known for its effect on coagulation, vitamin K also plays a fundamental role in calcium homeostasis. In fact, it does not allow an excessive deposit of calcium in arteries and sends it to the bones.



Take 1-2 capsule per day.
