Frequently Asked Questions about fatty15
What is fatty15?
Fatty15 is a once-daily oral supplement that combats age-related breakdown, including strengthening cell membranes, maintaining mitochondrial function, and naturally activating receptors throughout the body and brain to regulate immunity, metabolism, mood, appetite, and sleep.* Fatty15 contains a single ingredient—pure pentadecanoic acid (C15:0).
What is C15:0?
C15:0 is a odd-chain saturated fatty acid found in whole-fat dairy products and in trace amounts in certain plants and fish. Growing scientific evidence supports C15:0 as the first essential fatty acid discovered in 90 years (currently there are only two other essential fatty acids, one Omega-3 and one Omega-6). "Essential fatty acids" are nutrients that our bodies do not produce themselves but are necessary for maintaining physiological health. Therefore, our main sources of essential fatty acids are food and dietary supplements. Fatty15 provides an easy way for people to meet their daily C15:0 needs. *
C15:0 is found where?
C15:0 is found in trace amounts in milk fat, as well as in some fish and plants. Before you significantly increase your dairy fat intake by consuming large amounts of butter, consider this: high dairy consumption not only raises the levels of beneficial fatty acids that improve your health, but it also increases your total fat intake—including some even-chain saturated fatty acids that are not good for your body—as well as your total intake of natural sugars in milk, such as lactose.
C15:0, a good saturated fat?*
As it turns out, not all saturated fats are created equal. While scientific evidence supports that odd-chain saturated fatty acids, such as C15:0, *have widespread health benefits, even-chain saturated fatty acids (e.g., C16:0) are still associated with negative health outcomes. Based on these differences, global nutritional experts are calling for a revision of dietary guidelines to better reflect the health benefits of odd-chain saturated fats like C15:0.
Who invented FA15™?
Veterinary epidemiologist Dr. Stephanie Venn-Watson, in her dedication to improving the health and welfare of aging dolphins, discovered the potential benefits of C15:0. She initially observed that the healthiest aging dolphins had higher concentrations of C15:0 in their diets.
Three years and eight studies later, Stephanie and her team demonstrated that C15:0 is an active and beneficial fatty acid, meeting the criteria for the first essential fatty acid discovered in 90 years. These findings were published in the peer-reviewed journal, Scientific Reports. The team developed FA15™ to provide a sustainable, pure, vegan-friendly, and easy-to-take daily source of C15:0.
What is the recommended age to start taking fatty15?
Our only ingredient in fatty15, C15:0, is GRAS (Generally Recognized As Safe) certified, which means fatty15 is safe for children over 48 months old, pregnant and breastfeeding mothers, and almost everyone (except infants and toddlers). Our bodies generally continue to thrive until around age 30. After 30, our bodies begin to break down due to increasingly fragile cells, declining mitochondrial efficiency, and imbalances in immunity and metabolism. By age 40, these changes can lead to chronic health issues and require more medications for treatment. As we age, starting from 65, we may become increasingly frail and fatigued.
Therefore, taking fatty15 at a younger age may help maintain health... when you are between 30 and 65, it can make your body more resistant to age-related breakdown... and when you are over 65, it can also help restore some resilience and vitality.*
Do I need to keep taking fatty15 to maintain the results?
A growing body of scientific evidence supports C15:0 as the first essential fatty acid discovered in 90 years (currently, there are only two other essential fatty acids, Omega-3 and Omega-6). "Essential fatty acids" are nutrients that our bodies do not produce themselves but are necessary for maintaining physiological health. Therefore, our main sources of essential fatty acids are food and dietary supplements. Fatty15 provides a simple way for people to meet their daily C15:0 needs. *
What are the benefits of taking fatty15 compared to only consuming dairy fat containing C15:0?*
While whole fat dairy products do contain trace amounts of C15:0 (our good saturated fat), these foods also contain more of the detrimental saturated fats (e.g., C16:0) and have been associated with negative health outcomes. * Additionally, unlike dairy, fatty15 contains vegan-friendly, non-dairy, and lactose-free C15:0.
How/when do you take fatty15?
Fatty15 can be taken with or without food.
Since the short-term benefits peak 4 to 6 hours after supplementation, most users take fatty15 in the morning. Some have also found that taking fatty15 at night helps with sleep. Ultimately, you can adjust your fatty15 regimen according to your needs.
Can I take it if I'm doing intermittent fasting?
Yes! Fatty15 has only 1 calorie, and about half of fatty15 customers experience less hunger between meals, so it actually helps some people through their fasting period.
Can I take more than one fatty15?
We currently recommend customers start with one capsule daily to support the long-term cellular health benefits of fatty15, which can take 3-6 months of consistent use to be fully realized. About two-thirds of customers also report at least one short-term benefit within 6 weeks of starting fatty15, including improved sleep, reduced snacking, and a calmer mood. Some customers choose to take two capsules daily (safety studies have been completed up to 250 mg or 2 1/2 capsules) and share that doing so improves short-term benefits.
Does fatty15 have third-party testing?
We go beyond typical supplement testing to assure the quality of fatty15 and its sole ingredient, FA15™ (our pure powder and natural C15:0). FA15™ is manufactured under the highest cGMP conditions in an FDA-approved and food-registered manufacturing facility. FA15™ utilizes analytical procedures validated by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) to confirm ≥98% purity of every batch of FA15™. We also evaluate six additional attributes of fatty15, including with third-party testing, before release. All of this work—which is uncommon for supplements—is to ensure we are providing you with the highest quality fatty15.
Is fatty15 only for women?
Fatty15 is suitable for women, men, non-binary individuals, transgender people, seniors, young people... almost anyone with cells. It is currently safe for children aged 4+, men, women, pregnant women, breastfeeding mothers, and almost everyone (excluding infants and toddlers).
Will fatty15 make me gain weight?
No. A single capsule of fatty15 contains less than 1 calorie. In fact, by allowing fatty15 to help your cells work more efficiently, your body can be busy burning energy rather than just storing it (as fat).*
Are there any side effects to fatty15?
Since the discovery of C15:0 as an essential fatty acid in 2020 and its market launch in 2021, over 77,000 customers have taken fatty15 with very few side effects. While we cannot confirm if these side effects are directly attributable to C15:0 supplementation, the following symptoms have been reported by less than 0.1% of users: constipation, diarrhea, or headache.
Is it safe to take during pregnancy?
Our ingredient is GRAS certified (Generally Recognized As Safe), meaning fatty15 is safe for pregnant and breastfeeding mothers.
Are fatty15 supplements vegan?
Yes, they are vegan-friendly. In addition to being vegan, our products are dairy-free, gluten-free, and come in their purest form. They contain no preservatives, oils, animal by-products, corn, soy, or artificial colors.
How does Fatty15 compare to Omega-3?
Fatty15 (C15:0) is an odd-chain saturated fatty acid, while Omega-3 is a polyunsaturated fatty acid. While both are beneficial fats that support a healthy immune response, their roles are distinctly different. For example, fatty15 is a sturdy fat that strengthens cell membranes and protects cells from lipid peroxidation, which causes aging. In contrast, Omega-3 is a less stable fat that makes cell membranes more flexible but is more susceptible to oxidation as we age. The key is that our bodies use both C15:0 and Omega-3 to maintain health, and they can and should complement each other. What are the benefits of fatty15 with pure C15:0? Small pills, no smell, no taste, and no burps. Even better, fatty15 offers three times the cellular benefits for our immune, metabolic, heart, and liver health when directly compared to pure EPA. We recommend that you work with your healthcare provider to find the best supplement combination for you.
Can I take fatty15 with other vitamins and supplements?
Fatty15 is developed to supplement your diet and existing wellness routine. To date, no specific contraindications have been identified between fatty15 and other supplements or vitamins. Your health is our priority, and we encourage you to discuss with your healthcare provider before starting any supplement regimen.
Does fatty15 have a taste?
No. It's a pure powder with no additives, and no flavor or taste.
How should I store fatty15?
Fatty15 capsules can be stored at room temperature (in a reusable, eco-friendly glass bottle).
Can fatty15 be taken with prescription medications?
*For details regarding prescription medications, professional advice is recommended.*
Fatty15 was developed to complement your diet and existing health plan. To date, no specific contraindications have been found between Fatty15 and prescription medications. Your health is our top priority, and we encourage you to discuss with your healthcare provider before starting any supplement regimen.
Why do some capsules appear to contain different amounts of pure FA15™ powder?
Many supplements use fillers to fill each capsule completely. Fatty15 contains no fillers, only 100mg of pure powdered FA15™. As a result, some capsules may show varying amounts of FA15™. Specifically, 100mg of FA15™ may fill (more or less) 50% of the capsule, depending on storage conditions, powder compaction, and relative humidity. This variation is normal for our pure powdered FA15™.
