Healthy bones and joints with natural ingredients

Taking care of our bones and joints is a very important task that we should pay attention to throughout the year and that should be part of our daily routine in order to lead a healthy lifestyle.

What are joints?

Joints are the connections between two or more bones. Most joints, such as shoulder or knee joints, allow movement or rotation. Bones provide protection for some internal organs and hold the calcium stores of the body.

What factors may affect osteoarticular health?

Ageing, rheumatic or degenerative diseases, lifestyles such as intense physical exercise, sports injuries, work-related injuries or accidents, among other factors, may change the composition of the osteoarticular system, leading to muscular or joint conditions that reduce movement.

Does cold affect joints and bones?

Some people are affected by discomfort in certain joints such as knees, hips or wrists when temperatures drop, especially in the colder winter months, which can affect joint flexibility.

What exercises help osteoarticular health?

Physical exercise and nutrition are the main allies in promoting good bone and joint health.

Some exercises to strengthen muscles, bones and joints will help us against possible injuries and inflammations, though we should always be careful not to force the joints when there is any kind of pain and ask your physiotherapist for advice in severe cases.

Sports such as swimming, walking, yoga or Pilates help flexibility and muscle tone

We must add a proper nutrition that provides the necessary nutrients for good osteoarticular function, as well as a balanced and varied diet with natural supplements that include active ingredients for flexibility and mobility in bones and joints.

What natural ingredients can help bones and joints?

Collagen for bones and joints

Collagen is a protein present in the body, found in the skin, cartilage and connective tissues, and is an important part of the structures of the body.

As we age, the collagen we have in our body decreases. It is therefore necessary to supplement the diet with an extra supply of collagen to ensure the maintenance of osteoarticular health or especially when there is any kind of pain or discomfort.

Collagen can be found in the diet by eating meat, fish or gelatine. There are also food supplements available on the market containing collagen and other natural nutrients such as vitamin C and magnesium, which together help the normal production of collagen and the maintenance of bones and muscles.

Calcium for healthy bones

The health of our bones and joints also depends very much on the supply of calcium we give them. As well as helping organs and tissues, this mineral also contributes to the proper functioning of nerves, cells and muscles.

It is only available through the calcium-containing products we eat, which is why it is important to include calcium-rich foods in our diet, and can also be supplemented with food supplements. Calcium is found in the diet through the intake of milk, yoghurts, cheese, sardines, legumes, almonds, etc.

Vitamins A, C, D and K for bone and joint health

An appropriate intake of vitamins A, C, D and K is important for bone and joint health. In the case of vitamin D, for example, its function is strongly related to calcium intake, as it helps the absorption and use of this mineral, and ensures that these organs and tissues keep their functions.

Vitamin K is also essential for proper bone growth

On the other hand, the body also needs foods rich in vitamin C (pineapple, mango, kiwi, etc.) to ensure normal collagen production for the correct functioning of bones and cartilage.

Finally, vitamin A, present in foods such as carrots and milk, helps the cell growth process in bones and joints.

Glucosamine, important for cartilage and tendons

Glucosamine is a natural substance found in the structure of cartilage and plays an important role in cartilage formation. Glucosamine is part of the exoskeletons or outer layers of some crustaceans, as well as the cartilage or bones of some animals, including parts such as the snout or heel of pigs, cows and rabbits.

Chondroitin, a key component of cartilage

Chondroitin is part of a large protein molecule (proteoglycan) that provides elasticity to cartilage, whose sources are of animal origin.

Chondroitin sulphate is one of the most sought-after active ingredients in food supplements for bones and joints and is often used in combination with other active ingredients such as glucosamine or hyaluronic acid.


Turmeric is widely used by Eastern cultures, is widely standardised in its main bioactive curcumin, and its properties help to reduce inflammation in joints and muscles.

MSM (Methylsulfonylmethane)

MSM is an organic sulphur compound that is the third most common nutrient in the human body. It plays an important role in bone and joint care, especially with regard to the joints. It also is part of the structure of proteins. Some foods which contain MSM are corn, tomatoes, fruit, tea and coffee, among others.
