Bonito peptides are a type of protein that are derived from bonito fish. Also known as skipjack tuna, bonito is a popular fish that is consumed throughout the world, particularly in Japan and other parts of Asia. The peptides derived from bonito fish are known for their potential health benefits, which range from improving muscle strength and endurance to reducing inflammation and supporting weight loss. In this article, we will explore what bonito peptides are, how they work, and the scientific research that supports their use as a health supplement.
What are Bonito Peptides?
Bonito peptides are short chains of amino acids that are derived from the muscle tissue of bonito fish. Amino acids are the building blocks of proteins, which are essential for the growth, maintenance, and repair of cells and tissues throughout the body. When proteins are digested, they are broken down into their component amino acids, which can then be reassembled into new proteins that are needed by the body.
Bonito peptides are formed when the protein in bonito fish is broken down into smaller peptides. These peptides can be further broken down into individual amino acids or used as intact peptides by the body. The specific amino acid sequence of bonito peptides can vary depending on factors such as the age of the fish and the processing methods used to extract the peptides.
How Do Bonito Peptides Work?
Bonito peptides are thought to work by promoting the synthesis of new proteins in the body. This process, known as protein synthesis, is essential for building and maintaining muscle tissue, as well as repairing damaged cells and tissues throughout the body. Bonito peptides are believed to stimulate protein synthesis by activating a signaling pathway in cells called the mTOR pathway. This pathway is responsible for regulating the growth and repair of cells in response to changes in nutrient availability and other signals.
In addition to promoting protein synthesis, bonito peptides are also thought to have anti-inflammatory and antioxidant properties. Inflammation is a natural response of the body to injury or infection, but chronic inflammation can contribute to a variety of health problems, including heart disease, diabetes, and cancer. Antioxidants, on the other hand, help to protect cells and tissues from damage caused by free radicals, which are unstable molecules that can cause oxidative stress and contribute to the aging process.
What are the Health Benefits of Bonito Peptides?
Bonito peptides have been the subject of numerous scientific studies in recent years, which have explored their potential health benefits. Some of the most promising research has focused on the following areas:
Improving Muscle Strength and Endurance
Several studies have suggested that bonito peptides may help to improve muscle strength and endurance by promoting protein synthesis. For example, a 2018 study published in the journal Nutrients found that supplementing with bonito peptides for eight weeks led to significant improvements in muscle strength and endurance in a group of older women. Another study, published in the Journal of the International Society of Sports Nutrition in 2019, found that bonito peptides improved muscle recovery and reduced muscle soreness after exercise in a group of male athletes.
Bonito peptides have been shown to have anti-inflammatory properties, which may help to reduce inflammation in the body. A 2017 study published in the Journal of Functional Foods found that supplementing with bonito peptides for six weeks led to significant reductions in inflammatory markers in a group of overweight and obese adults. Another study, published in the Journal of Agricultural and Food Chemistry in 2018, found that bonito peptides reduced inflammation and oxidative stress in a group of rats with liver damage.
Supporting Weight Loss
Bonito peptides may also be helpful for supporting weight loss. A 2019 study published in the Journal of Functional Foods found that supplementing with bonito peptides for 12 weeks led to significant reductions in body weight and body fat in a group of overweight and obese adults. The study also found that bonito peptides improved insulin sensitivity, which is an important factor in the regulation of blood sugar levels and the prevention of type 2 diabetes.
Supporting Skin Health
Bonito peptides have also been shown to have potential benefits for skin health. A 2019 study published in the Journal of Cosmetic Dermatology found that supplementing with bonito peptides for 12 weeks led to significant improvements in skin hydration and elasticity in a group of women with dry skin. Another study, published in the Journal of Food Science in 2020, found that bonito peptides improved the appearance of wrinkles and fine lines in a group of middle-aged women.

Bonito peptides are a type of protein derived from bonito fish that are known for their potential health benefits. They work by promoting protein synthesis, reducing inflammation, and providing antioxidant support to the body. Scientific research has shown that bonito peptides may be helpful for improving muscle strength and endurance, reducing inflammation, supporting weight loss, and promoting skin health. If you are interested in exploring the potential benefits of bonito peptides for your own health, it is important to speak with your healthcare provider to determine if this supplement is right for you.
