Media about us:

At around the age of 25, your body starts to have problems synthesising collagen. On average, the level of this protein in your body decreases by more than 1.5 per cent each year. "What is that one per cent...", you are probably thinking to yourself.

.

Apparently nothing, but it's worth knowing what to expect so you can make informed decisions about diet or supplementation and how best to look after your health and beauty. Use Natu.Care's collagen calculator and assess your likely collagen levels right now.

How does the collagen calculator work?

.

The Natu.Care Collagen Calculator is a tool that estimates the levels of collagen in your body. It is developed based on data from several scientific studies such as Varani et al, 2006 or Kamp et al, 2022 (check the sources at the bottom of the page for details).

Please note that this is not a diagnostic tool and that real-world collagen levels may be different to those suggested by this calculator.

Scientific work suggests that the average annual loss of collagen - which starts to progress from age 25 - is about 1.65%. By the age of about 50, men and women lose collagen at the same rate, but the menopause period, accelerates the loss in women. 

During the first 5 years of this stage, you will lose ⅓ of all your current collagen. What's more, over the next 15 years the annual loss will be greater, at around 2.1%. This results in up to 13% less collagen at age 80 in women than in men.

Are collagen levels always the same in people of the same age?

.

No, collagen levels are also affected by other factors. The main and most important aspect that causes the loss of the youth protein is age. Nevertheless collagen in the body is destroyed also:

  • oxidative stress,
  • .
  • UV radiation,
  • .
  • deficiency vitamins and minerals,
  • smoking,
  • .
  • abuse of alcohol,
  • .
  • consumption of large amounts of sugar,
  • .
  • excessive stress,
  • .
  • lack of exercise,
  • .

By avoiding these factors, you will reduce the loss of collagen from the body and therefore avoid the symptoms of collagen deficiency, such as poorer skin condition, weakened nails or joint pain.

What indicates low collagen levels in the body?

.

Low levels of collagen in the body can manifest in a number of ways. The protein of youth is the basic building block of skin, hair, nails and tendons and joints. A drop in its levels can be seen as a number of physical changes, as well as abnormalities in general wellbeing.

    .
  • Wrinkles and dry skin. Low collagen levels lead to a loss of skin firmness and elasticity, resulting in the appearance of wrinkles. The skin can also become dry and less supple.
  • .
  • Weak hair and nails. Collagen plays a key role in maintaining healthy hair and nails. If you're noticing that your strands are becoming thin and brittle and your nails are becoming brittle, this could be a sign of low collagen levels.
  • .
  • Joint problems. Collagen is also an essential component of the joints, so a deficiency can lead to discomfort, pain or stiffness in these elements.

How to increase collagen levels in the body?

.

Everyone loses collagen in the body. But not everyone responds to it adequately. The best way to delay the signs of ageing is with a balanced diet, the right amount of exercise, general lifestyle hygiene and supplementationthe most powerful collagen preparations not only contain the right doses of this ingredient, but are also distinguished by their well-absorbed forms and valuable active ingredients.

FAQ

.
. Why does the menopause cause a faster loss of collagen?.

Menopause leads to a significant drop in estrogen levels, which negatively affects collagen production. Menopausal women experience accelerated skin ageing and collagen loss, leading to dryness, loss of elasticity and the appearance of wrinkles.

. Do men also need to be concerned about declining collagen levels?.

Yes, collagen decline affects both men and women. Although women experience a more rapid loss of collagen during the menopause, men also lose collagen from the body as they age. Its low levels in men can lead to similar symptoms, such as joint weakness, loss of skin firmness and deterioration of hair and nails.

. Is it possible to stop collagen loss?.

It is not possible to stop collagen loss completely as it is a natural process of ageing. However, you can take steps to slow down this process. Leading a healthy lifestyle, avoiding overexposure to the sun, limiting alcohol intake and avoiding smoking can help slow down collagen loss.

. Should athletes supplement with collagen?.

Collagen is an important component of healthy joints, so athletes and those with active lifestyles may see benefits from its supplementation. It can help maintain joint flexibility, which is important for injury prevention.

. Can collagen supplementation slow down skin ageing?.

Collagen is an important component of the skin that promotes firmness and elasticity. As we age, the skin's natural collagen stores decrease, leading to a loss of firmness and the appearance of wrinkles. And research suggests that collagen supplementation can help improve the appearance of skin.

. Are there any side effects of collagen supplementation?.

As with all dietary supplements, there is a risk of side effects during collagen supplementation. Although these are rare, they can include stomach discomfort, a feeling of heaviness in the stomach, skin rashes and other allergic reactions.
