Frequently Asked Questions

General
  • 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.*

  • How is C15:0 a good saturated fat?*

    Ends up, not all saturated fats are created equal. While scientific evidence supports broad health benefits of odd-chain saturated fatty acids (like C15:0)*, even-chain saturated fats (like C16:0) continue to be associated with negative health effects. Due to these differences, there has been a global call to action from nutritional experts to revise the dietary guidelines to better reflect the health benefits of odd-chain saturated fats, like C15:0.

  • What is FA15™?

    FA15™ is a pure powder form of C15:0 - the only ingredient in fatty15. Developing a high quality, environmentally sustainable form of C15:0 that meets diverse dietary needs was our highest priority. The result, FA15™, is vegan-friendly and lactose-free with no preservatives, no fillers, no oil, no dairy (or other animal products), no gluten, no allergens, and no artificial colors. Simply, one ingredient that is good for you and good for the planet, too.*

  • What is the recommended age to start taking fatty15?

    Our bodies tend to build up until we are about 30 years old. After 30, our bodies start to break down due to increasingly fragile cells, less efficient mitochondria, and imbalanced immunity and metabolism. By our 40s, these changes can result in chronic health conditions, along with more pills to address them. As we age from 65 on up, we can become increasingly fragile and fatigued.

    So, taking fatty15 when you’re younger may help keep your healthy body healthy…when you’re 30 to 65, it can make your body more resilient against aging-related breakdown…and when you’re older than 65, it can work to restore some of that resilience and energy.*

  • 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.

  • Will I feel a difference?

    Due to differences among individuals, some may feel a difference, while others may not. Rest assured, fatty15 is working hard to strengthen your cells, get your mitochondria working, and restore balance to your immunity and metabolism.* In turn, these cellular effects may make you feel more energized, less stressed, and generally healthier.* Consider fatty15 your long-term investment in you.

  • Will I need to continue to take fatty15 in order to maintain results?*†

    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.*

  • Do I need to take fatty15 daily?*

    Given the growing scientific evidence of C15:0 as an essential fatty acid needed to maintain physiological health, fatty15 should be taken daily.*

  • 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.

  • Is fatty15 only for women?

    Fatty15 is for women, men, non-binary, trans, old, younger...pretty much anyone with cells. It is currently for people 18 years or older.

  • Will fatty15 increase my weight?

    No. One capsule of fatty15 has less than 1 calorie. In fact, by letting fatty15 help your cells work more efficiently, your body can get busy expending energy instead of just storing it (as fat).*

  • Are there any side effects?

    There are no side effects known to date. As a micronutrient in milk and some fish and plants, C15:0 has been a natural, essential part of our diet since well...we’ve been humans.

  • Is it safe to take when pregnant?

    We have not yet studied fatty15’s effects during pregnancy. As such, it is currently not recommended for women when pregnant or trying to conceive.

  • Is fatty15 made in America?

    Fatty15 is encapsulated, packaged, and shipped in the good old USA.

  • Is fatty15 FDA approved?

    By law, the FDA does not approve dietary supplements. However, fatty15 is manufactured in accordance to the FDA’s current Good Manufacturing Practices (cGMPs), which help ensure quality and safety.

  • 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.

  • When should I take fatty15?

    We recommend taking fatty15 with a meal or in your hot coffee in the morning. Good fats are typically best absorbed when ingested along with other foods.

  • 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.

  • What if I already take an omega-3 fatty acid supplement?

    There are additional benefits to taking fatty15. While evidence supports that both FA15™ (the C15:0 ingredient in fatty15) and omega-3 fatty acids can improve health, there are important differences.* For example, FA15™ increases the resilience of our aging cells, while omega-3 fatty acids result in flexible cells that can be more susceptible to lipid peroxidation and cellular breakdown with age.*

  • Does fatty15 have any flavor or taste?

    No, it does not. It is a pure powder with no additives, and it has no flavor or taste.

  • How should I store fatty15?

    Fatty15 capsules can be stored at room temperature (in your refillable, earth-friendly glass bottle).

  • Can fatty15 be taken with prescription medication?

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

  • How big are the capsules?

    Fatty15 capsules are smaller and easier to swallow than most supplements. 

  • Have you done clinical studies?

    There is a growing body of studies demonstrating associations between higher C15:0 and good health in humans.  Further, multiple lab based studies have confirmed that higher C15:0 can provide direct health benefits.* For more information about these studies and more, please click here. Clinical trials with FA15™ are in development and will soon be underway.

  • 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.

  • Why do some capsules appear to contain different amounts of pure FA15™ powder?

    Many supplements use fillers to completely fill each capsule.  Fatty15 contains no fillers, just 100 mg of FA15™ in a pure, powder form.  As a result, some capsules may appear to have different amounts of FA15™ in each capsule.  Specifically, 100 mg of FA15™ has the potential to fill (more or less) 50% of the capsule, depending on the way in which it is being stored, how closely the powder is packed, and the relative humidity.  This variability is normal for our pure, powder form of  FA15™.  Sometimes, however, due to automated machinery, a capsule doesn't get all the FA15™ love it needs.
