Human growth hormone (HGH) is an important hormone produced by the pituitary gland.
Also known as growth hormone (GH), it plays a key role in growth, body composition, cell repair and metabolism (1, 2, 3, 4, 5, 6).
HGH also boosts muscle growth, strength and exercise performance, while helping you recover from injury and disease (4, 7, 8).
Lower HGH levels may negatively impact your quality of life, increase your risk of disease and make you gain fat (9).
Having optimal levels is especially important during weight loss, for recovery from injury and when trying to boost athletic performance (10, 11, 12, 13).
Interestingly, your diet and lifestyle choices can have a huge effect on your HGH levels (6, 14).
Here are 11 evidence-based ways to increase human growth hormone (HGH) levels naturally.
