What are the benefits of IGF-1?

Insulin-like Growth Factor 1 (IGF-1) offers several significant benefits, key among them being its roles in metabolic processes, tissue repair, and general vitality. Here are some specific benefits outlined by Andrew Huberman:

1. Metabolism and Energy: IGF-1 contributes to higher metabolism, aiding in fat loss and muscle growth. It synergizes with growth hormone to increase ATP production, which enhances cellular energy levels, thereby improving overall energy and vitality 1.

2. Hair Growth: Increasing IGF-1, either naturally through sleep and growth hormone or via medications, can lead to enhanced hair growth, as growth hormone stimulates the production of IGF-1 2.

3. Memory and Cognition: IGF-1, released in response to exercise, plays a substantial role in enhancing memory and cognition. Although it doesn't increase neurogenesis in humans as it does in other animals, its impact on cognitive functions is notable 3.

These benefits are tied closely with growth hormone, as IGF-1 is often released in response to growth hormone and carries out several parallel functions that help maintain the body's youthfulness and energy. However, it's important to note that treatments involving IGF-1 carry potential risks like increased cancer risk due to its growth-promoting properties on all cells, including malignant ones 2. Always consult with a healthcare provider before exploring treatments involving IGF-1.
