Capsule with Vitamin K2 and, D3, Calcium and Magnézium

The Four Pillars of Bone Health

Calcium: The Bone Building Material

All cells and tissues need calcium. In addition to ensuring bone strength , it plays a major role in the regulation of cellular processes, hormone formation, muscle and nerve trigger, and blood coagulation. 1, 2 Human body does not produce calcium, so it is necessary to replenish the amount consumed, primarily from food.

Magnesium: Calcium's Pair

Magnesium plays an important role in each step of vitamin D activation and in the production of parathyroid hormone which  regulates calcium levels. In case of magnesium deficiency, calcium will not (only) be incorporated where it is needed, but also where it is not (in the blood vessels, joints, or soft tissues) – this results in arteriosclerosis. Magnesium balances the absorption and utilization of calcium. 3-5

Vitamin D: The Key to Calcium Absorption

Vitamin D contributes to:

  • the normal absorption  of calcium and phosphorus
  •  maintaining normal calcium levels
  • maintaining normal bone and tooth structure
  • maintaining normal structure of teeth
  • maintaining healthy muscle function
  • normal immune system
  • normal cell division 6

Vitamin K2: Directs the Calcium We Consume to Where It's Needed

Vitamin K2 (menaquinone, MK) activates two calcium transport proteins:

  • activated calcitonin helps direct calcium and incorporate it into the bone. Vitamin K2 supplementation can stop or reverse bone loss;
  • activated matrix-Gla protein (MGP) helps to remove calcium from the vascular wall and soft tissues which helps in peventing atherosclerosis. 7, 8

Vitamins D3 and K2, as well as Magnesium Play an Important Role in Regulating Calcium Levels

Regulation of calcium levels is largely based on the action of three hormones (parathyroid hormone, vitamin D, and calcitonin).

When calcium level is too low, parathyroid hormone increases it. Magnesium plays an important role in the production of parathyroid hormone.

If calcium level is too high, the thyroid gland raises the  production of calcitonin – this helps to incorporate calcium into the bones. Vitamin D is required for the production of calcitonin and vitamin K2 is essential for its activation. 5, 9, 10

Why Do We Need the Co-ordinated Effects of the Four Agents for Bone and Cardiovascular Health?

Calcium Needs Magnesium, Vitamin D3, and Vitamin K2 to Exert its Beneficial Effects

Calcium alone will not be absorbed adequately. 11

  • Calcium + Vitamin D3 may increase the risk of cardiovascular events 12,13
  • Calcium (and Vitamin D3): friend or foe? It depends on vitamin K2.8
  • Magnesium is needed to activate vitamin D. 4, 5 

Vitamin D3- és K2: the Untapped Potential

What could be achieved with an optimal level of vitamin D3 and K2?

The lower limit of the desired range of vitamin D3 levels for calcium metabolism is 75 nmol / l. Increasing vitamin D3 level from 37.5-50 nmol / l to 75-100 nmol / l would result in a spectacular reduction in the incidence of the most widespread and difficult to treat diseases, and in overall mortality.14, 15

What Makes Osteo-Optima Capsule Special?

  • Effective: High content of Vitamin K2 and D3
  • Proven Active Ingredients: Contains the brands of Vitamin K2 and D3 used in many clintical trials 17, 18
  • Quality: MenaQ7 Crysals (95% purity, min 99.5% MK-7, 100% trans form) 19

Suppement Facts

Active ingredient in two capsules: 100 µg vitamin K2 (MenaQ7), 50 µg (2000 IU) vitamin D3, 120 mg calcium, 60 mg magnesium.

Quantitative composition reflects two major priorities: high vitamin K2 and D3 content, and once daily dosing. Recognizing the importance of vitamins K2 and D3 is one of the greatest achievements of the last decade.

Who Should Supplement with Osteo-Optima Capsulet?

Individuals with conditions related to vitamin D3 and/or K2, calcium and / or magnesium deficiency, and women over 40

If you are taking calcium, magnesium, vitamin D3, or vitamin K2, you should consider taking the rest.

The use of Osteo-Optima caőpsules is recommended to those suffering from and / or at risk of vitamin D3 / vitamin K2 / magnesium deficiency related conditions / diseases, and to women over 40 years of age. 20, 21
