Weak and brittle bones are a thing of the past. Let Bonical-K turn your bones rock solid.

Packed with calcium, vitamin D, and vitamin K2, Bonical-K is like a superhero for your bones and joints. Calcium provides the foundation for strong bones, while vitamin D3 helps your body absorb that calcium. Whereas vitamin K2 helps calcium deposition.





Increases Calcium Absorption

Prevents Bone Loss

Improves Bone Strength

Bonical-K contains all the essential nutrients that ensure optimum bone health. It contains calcium, the prime nutrient to ensure bone health, and vitamins D and K which ensure the optimum absorption of calcium by the bones.


Calcium, Vitamin D3, and Vitamin K2 are the ultimate nutrients for strong and healthy bones. Your bones are made from collagen and are hardened by calcium. For your bones to absorb calcium, you need the most absorbable form of Vitamin D, i.e., Vitamin D3 (cholecalciferol). Vitamin K2 is an essential nutrient in the bone-building process. Not only it promotes calcium deposition in the bones, but it also works against bone-loss mechanisms.

So if you’re ready to give your bones the love and attention they deserve, look no further than Bonical-K.

Bonical-K contains 500 mg of calcium, an important mineral that makes up your bones and gives them strength. Adequate calcium intake helps ensure that your bones have sufficient mineral density. Higher bone density translates to stronger bones that are less prone to fractures and breakage.

Calcium Absorption

Vitamin D3 in Bonical-K is crucial in calcium absorption and utilization. It helps your body absorb calcium from the intestines and incorporate it into bone tissue. Vitamin K2 works synergistically with calcium and vitamin D3 to promote bone health. It helps direct calcium to the right places in the body.

Bone Loss Prevention

Sufficient calcium levels help prevent the body from leaching calcium from the bones to maintain normal blood calcium levels. Calcium is essential for bone formation. Osteoblasts, specialized bone cells responsible for bone formation, use calcium to produce new bone matrix, reinforcing and strengthening the bone structure.



Calcium is a mineral that is required for strong bones and teeth. It aids in blood clotting, muscle contraction, and the regulation of normal heart rhythms and nerve functions. About 99% of the calcium in the body is stored in bones, with the remaining 1% found in blood, muscle, and other tissues.

The body obtains the calcium it requires in two ways. One method is to consume calcium-containing foods or supplements, while the other is to draw calcium from the body. If one does not consume enough calcium-rich foods, the body will remove calcium from the bones.

Sources of calcium are Milk, yogurt, green leafy vegetables for example broccoli, salmon, almonds, nuts, beans etc.

Daily recommended amount of calcium:

From Birth to 6 months: 200 mg

Infants from 7 to 12 months: 260 mg

Children 1 to 3 years:        700 mg

Children 4 to 8 years: 1,000 mg

Children & Teenagers:  9 to 18 years: 1,300 mg

Adults 19 to 70 years: 1,000 mg

Adult women 51 to 70 years: 1,200 mg

Adults 71 years and older: 1,200 mg

Pregnant and breastfeeding teens: 1,300 mg

Pregnant and breastfeeding adults: 1,000 mg

Lack of adequate calcium may lead to Osteoporosis (weak, fragile bones and higher chance of fracture), Rickets (weak bones of children), and Osteomalacia (soft bones in children and adults).
It is recommended to take 400-800 IU of vitamin D each day.
Some vitamin K2 food sources may not be recommended in high quantities. Sources of vitamin K2 are Collards, Spinach, Egg yolks, Turnip greens, fermented soy, Chicken breast, Fermented milk (kefir), Blue cheese, Chicken liver & Butter.
Vitamin K2, a fat-soluble vitamin, is known for its important role in bone building and maintenance, as well as inhibiting calcium deposits in arteries and blood vessels. It is also known to play a role in coagulation, but vitamin K1 plays a larger role in this process. Vitamin K2 is essential for directing calcium to build strong, healthy bones and preventing calcium from depositing in arteries and soft tissues.

Vitamin D is required by the body to build and maintain healthy bones. Vitamin D is required for absorption of calcium, the primary component of bone. Many other cellular functions in the body are also regulated by vitamin D. Its anti-inflammatory, antioxidant, and neuroprotective properties help to maintain immune function, muscle function, and brain cell activity. It inhibits the release of parathyroid hormone, a hormone that maintains calcium balance.

Vitamin D also aids in the regulation of phosphate levels in the body. Phosphate is essential for bone growth and mineralization. It’s also a crucial part of DNA and RNA. Vitamin D has been shown to increase the production of microbe-fighting proteins by immune cells.

Recommended Dietary allowances (RDA) for vitamin D:

  • Up to 12 months: 400 IU per day
  • 1 year to 70 years: 600 IU per day
  • Pregnancy & Nursing mothers: 600 IU per day
  • 70 years and above: 800 IU per day.



Lack of vitamin D may not always exhibit symptoms and signs. Sometimes a person could have vitamin D deficiency but remains asymptomatic. In children, vitamin D deficiency may cause rickets. Problems associated with lack of vitamin D vary from having weak or soft bones, bone pain, muscle pain, cramps and weakness, mood changes, depression to unhealthy growth patterns & joint deformities. Those with such deficiency may be likely to get respiratory infections, or even autoimmune health problems.

Certain conditions may lead to vitamin D deficiency:

  • Cystic fibrosis, Crohn’s disease and celiac disease: Conditions that may hamper absorption of vitamin D.
  • Kidney disease and liver disease: These conditions may reduce certain enzymes required for vitamin D conversion. 
  • Obesity: Vitamin D is kept isolated by the fat cells and its release may be affected. Those people having this condition may require larger doses of vitamin D to attain normal levels.
Vitamin D level could decrease with age. Those who have a darker skin colour may require higher sun exposure to make the required vitamin D.
Vitamin D3 promotes the absorption of calcium by the body.
Bonical-K is one of the best vitamin D supplements in Pakistan. It also contains calcium and Vitamin K2.
