Aging is inevitable, but the way we age may be affected by the strength and health of our cells. Fragile and damaged cells may leave us more susceptible to illness and aging. (1)

While a healthy diet and exercise are critical steps to maintaining vital cells, scientists have recently discovered a new nutrient that may aid in keeping our cells youthful.

This fatty15 review discusses the story behind the brand, the evidence and safety of its formula containing the fatty acid, how it may help you feel healthier and age better, and its safety to help you decide if it’s the right choice.

What Is Fatty15?

Fatty15 is a fatty acid C15:0 supplement that can support cellular health, boost your mitochondria, and ward off age-related illness.

An essential fatty acid refers to fatty acids that the body cannot make and are crucial to getting into the diet.

Fatty15 supplement is designed to replenish the body with this critical fatty acid that has been declining from the modern diet for years.

Our primary dietary source of fatty acid C15:0 is whole-fat dairy products. However, even in butter and whole-fat milk sources, C15:0 is available in minimal amounts. (2)

These foods also contain higher even chain fatty acids, which may increase the risk of heart disease, inflammation, and type 2 diabetes. (3)

Fatty15’s unique formula offers a pure form of essential fatty acid C15:0 as a vegan-friendly dietary supplement.

Supplementation requires one pill a day, every day. It is recommended to take Fatty15 on an ongoing basis and as part of your current health regime to receive ultimate health benefits.

How Was Fatty15 Discovered?

While observing a pod of dolphins, Founders, and life partners, Dr. Stephanie and Dr. Eric Ven-Watson may have found what points to be the first essential fatty acid in 90 years called pentadecanoic acid, or C15:0. (2)

That was the start of the idea behind Fatty15.

Dr. Stephanie Ven-Watson, a former veterinary epidemiologist, began her studies to uncover how changes in the ocean impact the dietary needs of dolphins.

The researchers tracked two groups of dolphins, a pod in San Diego, California, and a group in Sarasota, Florida.

While both groups of dolphins were relatively healthy, they found that the California pod had more aging-related conditions than the dolphins in Florida.

Those aging-related conditions, similarly to humans, led to illnesses such as diabetes, heart disease, and stroke.

Upon further investigation, researchers found that the Florida pod ate fish with higher content of fatty acid C15:0.

Does Fatty15 Work? The Science Behind Its Claims

When taken daily and coupled with a healthy diet and exercise, Fatty15 may boost cellular mitochondria, improve cellular vitality, and promote health.

Evidence supports that odd chain fatty acid C15:0 is a newly discovered essential fatty acid that strengthens cell membranes, boosts mitochondria, and improves health. (4)

Below we break down each of Fatty15’s benefits for you and how the research backs up each of them.

Boost Mitochondria

Fatty15 supplement has been shown to boost mitochondrial function. (2)

Mitochondria are the energy powerhouses. They generate most of the chemical energy needed to power our cell’s critical functions.

A decline in mitochondrial quality and function has been associated with aging and correlates with age-related diseases. (5)

Research has found that individuals supplemented with C15:0 experienced repaired mitochondrial function and decreased risk for heart disease. (2)

In addition to optimal fatty acid intake, physical exercise is also crucial to mitochondria health. (6)

When coupled with a balanced exercise routine, Fatty15 may help combat the age-related decline in mitochondrial function.


A decline in mitochondrial health is linked to aging and aging-related disease. Studies have found that intake of fatty acid C15:0 improves mitochondrial function. When coupled with exercise, Fatty15 may enhance mitochondrial function.

Improves Cellular Health

Fatty15 supplement offers a pure and potent source of fatty acid C15:0.

Similar to mitochondria, a cell loses its ability to function over time.

Additionally, our cells become more at risk for damage as we age. (7)

As parts of the protective outer layer of the cell, fatty acids play a critical role in keeping the cell healthy. (2)

Research has shown that supplementation of fatty acid C15:0 strengthens cellular stability, protecting our cells from age-related wear and tear. (2)

The reality is that we age because our cells do, and because our body is made up entirely of cells, protecting our cells the best we can is critical to aging well.

While exercise, adequate sleep, and a healthy and varied diet are essential components of longevity, fatty acids, such as C15:0, may aid in slowing the age-related breakdown of our cells.


Our body is made up of cells, so keeping our cells healthy is critical to health and aging well. Research supports the intake of fatty acid C15:0 in strengthening cellular health. Fatty15 offers a pure and potent source of C15:0.

Promotes Mind and Body Health

Stronger cell membranes make both you and your cells more resilient.

When coupled with a varied diet rich in omega-3s, Fatty15 can increase the intake of fatty acid C15:0 and promote mind and body health.

Research supports that a higher intake of C15:0 is associated with a decreased risk of obesity, inflammation, cardiovascular disease, type 2 diabetes, metabolic syndrome, and other health conditions. (2)

In a 14-year study involving over 14,000 people, increased intake of odd chain fatty acids, such as C15:0, was associated with lower mortality in men and women. (2)

Additionally, clinical studies have identified that fatty acid C15:0 has similar properties to bupropion, a compound used to treat depression and other mood disorders. (8)

Further research found a link between intake of C15:0 and a reduction in anxiety. (8)

Intake of omega-3s alongside C15:0 may be a more natural approach to supporting mental health.

Food sources of omega-3 include:

  • Fatty fish, such as salmon, mackerel, and tuna
  • Nuts and seeds, such as flaxseeds, chia seeds, and walnuts
  • Oils, such as flaxseed oil and canola oil

Food sources of C15:0 include: (2)

  • Whole-fat milk
  • Butter
  • Some marine and freshwater fish

Keep in mind that food sources contain minimal amounts of C15:0, and vegan sources of C15:0 are much less available.


While there are food sources of C15:0, the fatty acid is present in low amounts and is much less available in vegan sources. When coupled with a healthy diet rich in omega-3s, Fatty15 may increase the intake of C15:0 and promote a healthy mind and body.
