Tiny and easy to swallow.

FA15™ (the pure, fatty acid powder in fatty15™) is a trace micronutrient. So our capsules are smaller and much easier to swallow than most supplements.

Planet-friendly packaging. And less of it.

Because everything we do is for a healthy you and a healthy earth, too. So every bottle, kit and pouch is made with renewable materials.

"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

"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

“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

“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

“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

"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

"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

"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 felt like it was really helping me regain some of my memory and that alone would have been enough for me to continue, then I realized I've been falling asleep easily and getting a good night's sleep 80-90% of the time; which is actually incredible for me, and an amazing gift

I felt like it was really helping me regain some of my memory and that alone would have been enough for me to continue, then I realized I've been falling asleep easily and getting a good night's sleep 80-90% of the time; which is actually incredible for me, and an amazing gift. No luck with the appetite abatement, but that's not why I started using it so that would have just been the cherry on top. Very well satisfied with the success I've had thus far!

Since taking this supplement, My husband and I both have experienced a significant decrease in our cholesterol levels

I actually have recommended to people already. Since taking this supplement, My husband and I both have experienced a significant decrease in our cholesterol levels. We have noticed such an improvement not only in our cholesterol but in our overall well-being that it has really made a difference.

I praise God for whoever creatively designed this product!

Been taking for almost 3 months and I praise God for whoever creatively designed this product! Joint / skeletal pain greatly reduced and in some areas gone completely. Sleeping better for sure. Overall feeling of wellness increased. Dry eye so much better - no more drops, gel, etc. Used to take fish oil - never will again.

I have only been taking fatty15 for two weeks and I’m amazed

I have only been taking fatty15 for two weeks and I’m amazed. I bought it in my quest for better sleep. I have had insomnia for over a year and I have and would try anything. The last few nights I have been able to go back to sleep after waking up in the middle of the night! And something I didn’t expect: my blood glucose levels have gone down. So much so that I’m thinking I’ll need to talk to my doctor about adjusting my medications. And, my aching hip has stopped hurting. I didn’t think this would actually work so well but, like I said, I would try anything. I’ll see if these results continue. If they do, this is life changing.

Asked, and answered.

Because scientists seriously love questions.

  • What is fatty15?

    Fatty15 is a once daily oral supplement working to counter age-related breakdown, including strengthening cell membranes, keeping mitochondria working, and advancing cellular homeostasis.* Fatty15 contains one ingredient - pure pentadecanoic acid (C15:0).

  • What is C15:0?

    C15:0 is an odd-chain saturated fatty acid present in trace levels in whole fat dairy products and some plants and fish. A growing body of scientific evidence supports that C15:0 is the first essential fatty acid to be discovered in 90 years (there are only two other essential fatty acids, one omega-3 and one omega-6 fatty acid).† “Essential fatty acids” are nutrients that our bodies don’t make but are necessary to maintain physiological health. As such, our primary sources of essential fatty acids are food and dietary supplements.  Fatty15 offers an easy way for people to meet their essential C15:0 needs, every day.*

  • What is the benefit of taking fatty15 over just eating more dairy fat (which contains C15:0)?

    While whole-fat dairy products contain trace amounts of C15:0 (our good saturated fat), these foods also contain much higher amounts of bad saturated fats (like, C16:0) that are associated with negative health effects.* In addition, unlike dairy products, fatty15 contains pure, vegan-friendly, non-dairy, and lactose-free C15:0.

  • How long before fatty15 starts working?

    Our studies support that fatty15 starts working between 1 to 3 months of once-daily oral supplement-taking. This is why our recommended starter kit has a 90 day (3 month) supply.

  • Can I take fatty15 with other vitamins and supplements?

    Fatty15 was developed to complement your diet and current health regime. To date, no specific contraindications between fatty15 and other supplements or vitamins have been identified. Your health is our top priority, and we encourage you to talk with your healthcare provider before beginning any supplement regimen.

  • Are fatty15 supplements vegan?

    Yes, they are vegan-friendly. In addition to being vegan, our product is dairy-free, gluten-free, and in the purest form. Free of preservatives, fillers, oil, animal byproducts, corn, soy, and artificial colors.

  • Is fatty15 and its packaging environmentally friendly?

    Yes! Our top two priorities are your health and the health of the Earth. From our ingredient, to your refillable glass bottle, and even to the package on your doorstep, we designed everything with these priorities in mind. To learn more click here.

  • How does the subscription work?

    Fatty15 will come in a starter kit, containing everything you need to start improving your cellular health. In the fully recyclable (and dare we say inspiring) kit, you will receive a 90-day (3-month) supply of fatty15 capsules to be placed in your reusable glass bottle, as well as an educational insert. The starter kit has a 90 day supply because our studies support that fatty15 can take up to 3 months to achieve its initial health benefits.
