Collagen gradually decreases with age
Collagen is the most abundant structural protein in the body, participating in the formation of skin, bones, cartilage and connective tissue. However, not everyone knows how long collagen exists in the body and how long it lasts.
According to pharmacist Ayesha Gulzar (USA) and assessed by Dr. William Truswell, a medical expert in the US, collagen supplements in the form of hydrolyzed (collagen peptide) can stay in the body for about 14 days after use.
The natural collagen production process begins to decline from around age 25. After 40 years old, the body can lose about 1% of its collagen each year, and this decline accumulates over time, clearly affecting the elasticity of the skin, bones and joints.
However, natural collagen in the body has different "lifespans" depending on each tissue. Collagen in the skin can last for many years, while collagen in the joint cartilage lasts almost a long time but has a slow recovery rate. Collagen in bones is regenerated in cycles, averaging about 10 years.
Regular supplementation is needed to maintain effectiveness
Collagen supplements are usually in the form of small peptides, which help the body easily absorb through the digestive tract. After entering the blood, these molecules are distributed to the skin and connective tissues, taking effect for a few weeks.
However, this effect does not last if you stop using it. Experts say that the benefits of collagen, such as improving skin moisture, elasticity or joint health, will gradually decrease after a few weeks if you do not continue to supplement it.
Many studies recommend using collagen continuously for at least 8 - 12 weeks to notice noticeable changes, especially with skin and hair.
In general, collagen is not an immediate solution but needs to be maintained regularly in combination with a reasonable diet and lifestyle to achieve long-term effects.
