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.

"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

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.
