My blood test after taking [fatty15] for 6 months [is the] best I have had in 10 years. Low lipids and perfect a1c.

— V.B.

comment

"I feel and look better, sleep better, easy to take. Blood work came back significantly better." - M.B.

comment

My anxiety feels at bay somehow and I feel much, much more leveled out. I’m genuinely in disbelief by how great I feel.

What the scientific community is saying

What the scientific community is saying

"What began as a passion for working with animals has resulted in an entrepreneurial journey of taking the science from the bay to the lab...and developing a product that people can take to improve health on a cellular level."
- Monica Haider, Forbes

"When Dr. Stephanie Venn-Watson started studying dolphins at the US Navy's marine mammal program, she wasn't expecting to turn the food pyramid on its head."
- Jessica Rendall, C|NET

"I'm a big believer in supplements so I was super intrigued to try Fatty 15, a supplement that is packed with good fats in order to help your cells age well from the inside out. Fatty15 uses only one ingredient: C15:0 (good fats!) to help arm your cells with what they need to age healthily.”
- Kelly Gallagher, Byrdie

"As for the future, Venn-Watson and her team had discovered about 100 molecules naturally present in the serum of both dolphins and humans, that looked like they could protect against the onset of aging-related diseases, so it is very possible we will see more to come from her team. But presently, this discovery of a new [essential] fatty acid is incredibly remarkable."
- Micki Wagner, Worth

"A new study, published by PLOS One, shows that an odd-chain saturated fat, called Pentadecanoic acid (C:15:0), may be healthier, safer, and more effective for supporting cellular health than the leading omega-3 fatty acid, eicosapentaenoic acid (EPA)."
- Sebastian Krawiec, Nutritional Outlook

"For decades there has been a war on fats such as butter, whole milk, and cheese. But for the first time in 90 years, a San Diego company made an amazing discovery of a new fat, present in butter, and one your body desperately needs."
– Steve Atkinson, KGTV ABC10 News

“In tests, daily oral supplementation with pure C15:0 for approximately 12 weeks supported healthier cholesterol and glucose homeostasis in obesity models and advanced hepatic form and vitality in liver disease models.”
– Vegconomist

"Similar to omega-3 fatty acids, Fatty15 is meant to boost immune and metabolic health, but without the fishy-smell omega-3 vitamins are known for."
- Alex Bitter and Ellen Thomas, Business Insider

“The growing recognition of C15:0 as an essential fatty acid, which now has evidence of being better, broader and safer than the purest, highest performing omega 3, provides a new option for consumers.”
- Nicole Kerr, NutritionInsight

“Known as pentadecanoic acid, or C15:0, the dietary saturated fat found in milk, butter, fish, plants and other foods was shown in studies to demonstrate broad health benefits. It would join omega-3 and omega-6 as the only fatty acids considered by nutrition scientists as essential.”
– Christopher Doering, FoodDive

“This discovery [by Seraphina Therapeutics] may elevate C15:0 to the ranks of now hallowed essential fatty acids omega-3 and omega-6 as well as usher in a new dialogue on changing the global guidelines for intake of dietary saturated fatty acids.”
– Karen Raterman, New Nutrition Business

Questions, answered by
doctors and scientists

fatty15

  • What is C15:0?

    C15:0 (pentadecanoic acid) is a healthy odd-chain saturated fatty acid. Fatty15’s co-founder, Dr. Steph Venn-Watson, discovered that C15:0 is not only a good fat, but that C15:0 meets the rare criteria of being the first essential fatty acid to be discovered since omega-3, which was over 90 years ago.

    In extensive peer-reviewed studies, C15:0 has been shown to support metabolic, heart, liver and immune health, as well as naturally activate receptors in our bodies that deepen sleep, reduce anxiety, and improve joint comfort.

    Essential fatty acids are nutrients that our bodies need to maintain baseline health but can't make. That means we must get these essential fats from our diet or supplements. Today, there are three known essential fatty acids: alpha-linolenic acid (an omega-3), linoleic acid (an omega-6), and now, C15:0. Because C15:0 has been shown to have 3x more cellular benefits than omega-3, C15:0 is emerging as the essential, essential fatty acid.*

  • Can’t I just get C15:0 from food?

    Our primary food-based source of C15:0 is whole fat cow’s milk, which contains trace amounts of C15:0. Dairy fat, however, contains much higher levels of pro-inflammatory even-chain saturated fatty acids (C16:0), as well as a wallop of calories. Food-based C15:0 is also tied up in complex lipids called triacylglycerides that make C15:0 less bioavailable.  We developed fatty15 to help consumers get >99.5% pure C15:0 in a vegan-friendly, science-backed and readily bioavailable form. No cows or calories needed.

  • Can fatty15 replace my omega-3s?

    You may be surprised to hear that the most recent studies show that taking omega-3 fish oil supplements does not significantly reduce the risk of developing heart disease, depression or mood disorders, frailty, autoimmune disease, dry eye disease or cognitive decline. This is likely because omega-3 fish oil supplements can be highly variable in omega-3 content and are particularly susceptible to lipid peroxidation, both of which can compromise the quality and effectiveness of omega-3 supplements. 

    In contrast, fatty15 was developed by doctors to provide a >99.5% pure, science-backed, vegan-friendly, patented and award-winning C15:0 ingredient. Pure C15:0 is an essential fatty acid and a stable powder that is resistant to lipid peroxidation. Each and every batch of fatty15 is tested to guarantee its purity, helping to ensure that you are getting only the good, essential fat that you need. Further, fatty15 has been shown to have 3x more cellular benefits than even the purest, highest performing omega-3.

    Given the above, most people can consider fatty15 as a replacement for their omega-3 supplements to support their general, long-term health. If you are taking omega-3s under the supervision of a physician, however, we recommend that you talk with your doctor before making any changes.

  • How does fatty15 help to restore sleep and reduce anxiety?

    While C15:0 is an essential nutrient to support our long-term body health, the latest science is revealing how fatty15 supports our mental health, too. First, the >99.5% pure C15:0 ingredient in fatty15 naturally activates PPARɑ receptors throughout our body and brain that can help to reset our circadian clocks, increase the amount of deep sleep we get, and lower our anxiety. Second, fatty15’s 36+ clinically-relevant cellular benefits have a 78% match to leading mood-supporting compounds. Finally, our bodies use C15:0 to make a second molecule that fully activates both CB1 and CB2 receptors, which can help to deepen sleep, reduce anxiety, and increase joint comfort.*

    Learn more about this latest groundbreaking discovery.

  • How does fatty15 help rebalance metabolism?

    Today, more than 50 peer-reviewed scientific studies have linked C15:0 (aka, pentadecanoic acid) to better metabolic, heart, immune and liver health. Our >99.5% pure, vegan-friendly C15:0 fatty acid in fatty15 rebalances our metabolism naturally by 1) activating PPAR-alpha and delta receptors, the master orchestrators of our metabolism, 2) activating AMPK pathways, which regulate glucose, 3) repairing mitochondria and enabling our cells to generate energy. Heck, that’s a bunch of much-needed benefits to help keep our metabolism balanced.*
