Definition: When does the production of IGF-1 decline?
Insulin-like Growth Factor 1 (IGF-1) is a hormone that plays a crucial role in growth and development, particularly during childhood and adolescence. It is produced by the liver and other tissues in response to the secretion of growth hormone (GH) from the pituitary gland.However, as individuals age, the production of IGF-1 naturally declines. This decline typically begins in early adulthood and continues throughout the aging process. Several factors contribute to the decrease in IGF-1 production, including changes in hormone levels, cellular senescence, and reduced sensitivity to growth hormone.

It is important to note that the decline in IGF-1 production is a normal part of the aging process and is not necessarily indicative of any underlying health issues. However, low levels of IGF-1 have been associated with certain age-related conditions, such as decreased muscle mass, impaired bone health, and increased risk of chronic diseases.
While the exact age at which IGF-1 production starts to decline can vary among individuals, it is generally believed to occur in the late 20s or early 30s. From that point onwards, the decline is gradual but becomes more pronounced with advancing age.

It is worth mentioning that lifestyle factors, such as diet, exercise, and sleep patterns, can also influence IGF-1 levels. Regular physical activity, adequate protein intake, and quality sleep have been shown to support healthy IGF-1 production.
In conclusion, the production of IGF-1 naturally declines with age, starting in early adulthood. While this decline is a normal part of the aging process, maintaining a healthy lifestyle can help support optimal IGF-1 levels and overall well-being.
