What is fatty15?
Fatty15 is a once daily oral supplement working to counter age-related breakdown, including strengthening cell membranes, keeping mitochondria working, and naturally activates receptors throughout your body and brain to regulate immunity, metabolism, mood, appetite, and sleep.* 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.*
Where can I find C15:0?
C15:0 is found in trace amounts in milk fat, as well as in some types of fish and plants. Before you increase your intake of dairy fat by gobbling on loads of butter, consider this: high consumption of dairy products won’t just increase your levels of good, healthy fatty acids, it will also increase your total fat intake, including some even-chain saturated fatty acids that aren’t good for your body, as well as your total sugar intake thanks to the naturally-occurring sugar in milk, lactose.
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.*
Who invented FA15™?
Dr. Stephanie Venn-Watson, a veterinary epidemiologist, discovered the potential benefits of C15:0 while working to improve the health and welfare of older dolphins. She initially found that the healthiest aging dolphins had higher C15:0 levels in their diets.
Three years and eight studies later, Stephanie and her team were able to show that C15:0 was an active and beneficial fatty acid that was meeting the criteria of being the first essential fatty acid to be discovered in 90 years. These findings were published in the peer reviewed journal, Nature's Scientific Reports. The team developed FA15™ to provide a sustainable, pure and vegan-friendly source of C15:0 that was easy to take every day.
Why the name fatty15?
About a year ago, we had many (many) discussions about how to name a newly discovered saturated fat (C15:0, or pentadecanoic acid) that science now supports as the first essential fatty acid to be identified in almost 100 years. With the growing number of studies showing that higher levels of odd-chain saturated fatty acids (including C15:0) are associated with better health, we wanted to highlight "good fats" that support whole body and mind health. More information about C15:0 can be found here.
What is the source of the ingredient in fatty15 (aka FA15 aka C15:0)?
To ensure that we provide the purest vegan-friendly ingredient to our customers, fatty15 is made from scratch (i.e. synthesized) using the highest quality assurance standards. Because our pure powder ingredient exactly matches the form of C15:0 found in nature, it is considered a natural ingredient.
What is the recommended age to start taking fatty15?
Our sole ingredient in fatty15, C15:0, is GRAS (generally regarded as safe) certified, which means fatty15 is safe for children age 4+, pregnant women, nursing moms, and pretty much everyone except for infants and toddlers.
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?
We have seen consumers experience near-term benefits within the first few weeks of taking fatty15. These include: Less snacking and hunger between meals; Deeper, better quality sleep and waking up feeling more refreshed; A calmer mood, less anxiety and better ability to cope with stress; and More energy that is better sustained throughout the day.*
For longer-term benefits, 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.
How do you take fatty15?
Fatty15 can be taken either with food or on an empty stomach. It is just that versatile of a supplement!
When should I take fatty15?
Since near-term benefits peak 4-6 hours after supplement taking, most customers take fatty15 in the morning. Others find taking fatty15 in the evening helps support their sleep. Bottom line, you can adjust your fatty15 regimen based on your needs.
Can I take if I am doing intermittent fasting?
Yes! Fatty15 is only 1 calorie, and since about half of fatty15's customers specifically experience less hunger between meals, it has actually helped some people get through their fasting periods.
Can I take more than 1 fatty15?
We currently recommend that customers start with taking 1 capsule a day to support the long-term cellular health benefits of fatty15, which can take up to 3-6 months of routine use to take full effect. About 2 out of 3 customers also report at least one near-term benefit within 6 weeks of starting fatty15, including better sleep, less snacking, and a calmer mood. Some customers have opted to take 2 capsules a day (safety studies have been completed for up to 250mg - 2 1/2 capsules) and have shared that this has resulted in improved near-term benefits.
How do you know C15:0 (pentadecanoic acid) works?
An extensive series of studies have shown that pentadecanoic acid improves cellular resilience, repairs mitochondrial function, and naturally targets receptors found throughout our bodies (called PPARs) that regulate our metabolism, immunity, mood, sleep and appetite.*
These studies also showed that daily supplementation with pentadecanoic acid promoted healthy glucose and cholesterol levels, as well as healthy liver and red blood cell function in relevant models.
Importantly, dozens of large scale population studies have linked C15:0 to better metabolic and heart health in humans.
Is C15:0 supplementation a better option?
If you want the health benefits of C15:0 but not the unhealthy saturated fats you’ll find in cows milk, full-fat butter, or other whole dairy products, taking a C15:0 supplement is the solution.
Fatty15 contains just one ingredient: pure, vegan-friendly FA15™ in pure powder form. Taking just one capsule a day can help support better health.*
Is fatty15 third party tested?
We are proud to share that we go above and beyond typical supplement testing to ensure the quality of fatty15 and its only ingredient, FA15™ (our pure powder and natural form of C15:0). FA15™ is made under the absolute highest cGMP conditions at FDA-approved manufacturing facilities that are also FDA food facility registered. FA15™ is tested using validated analytical procedures verified by ICH (International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use) to confirm the purity (≥ 98%) of each and every FA15™ batch. We also assess fatty15 for six other attributes, including use of third party testing, before it is released. All this work (which is rare for a supplement) is done to ensure that we are providing you the absolute highest quality fatty15.
Is fatty15 only for women?
Fatty15 is for women, men, non-binary, trans, old, younger...pretty much anyone with cells. It is currently safe for for children 4+, men, women, pregnant women, nursing moms, and pretty much everyone except for infants and toddlers.
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?
Since we discovered C15:0 as an essential fatty acid in 2020 and introduced the ingredient to market in 2021, over 17,000 customers have taken fatty15 with very few side effects. While we cannot confirm that these side effects are directly attributable to C15:0 supplementation, the following have been reported in less than 0.1% of customers: constipation, diarrhea or headache.
Is it safe to take when pregnant?
Our ingredient is officially GRAS (generally regarded as safe) certified, which means fatty15 is safe for pregnant women and nursing moms.
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.
In our commitment to make fatty15/FA15/C15:0 accessible to all, we have gone above and beyond to enforce the safety of fatty15 for those of all ages and life stages by receiving GRAS (Generally Recognized As Safe) status by the FDA.
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.
How is fatty15 different than an omega-3?
Science supports that both C15:0 (the only ingredient in fatty15) and omega fatty acids (specifically alpha-linolenic acid, an omega-3; and linoleic acid, an omega-6) are essential fatty acids that can help regulate your immune system and metabolism. There are a few extra benefits of fatty15, however, including the ability for fatty15 to help keep cells resilient against aging-related breakdown; omega-3 fatty acids can actually increase your cell's susceptibility to breakdown with age. Further, omega-3s are oily, fishy smelling, require large doses, are susceptible to oxidation (in the bottle and your body), and can cause burping and stomach upset. In contrast, fatty15 is a pure powder form of C15:0 with no taste or smell, requires only a single and small 100 mg dose per day for both near- and long-term benefits, is not susceptible to oxidation, and does not cause stomach upset.
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.
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. If you have any questions, please reach out to us via email at: firstname.lastname@example.org.
Should I still be taking my omega-3s?
Given the mounting science supporting C15:0 as the essential, essential fatty acid, including fatty15's demonstrated ability to repair and support your cells better, broader and safer than the leading omega-3, you may opt to use fatty15 in lieu of omega-3 fish oil supplements. One note; you should continue taking an omega-3 if prescribed by your doctor.
In our peer-reviewed study, we found that pure C15:0 (fatty15) had all of the cell-repairing benefits of the leading pure omega-3 (EPA). Further, C15:0 had an additional 26 clinically-relevant benefits. To learn more about fatty15's pure C15:0 supplements vs. marine oil omega-3 supplements, read here!
If I can’t take omega-3s, can I take fatty15?
Yes. There are many reasons that people don’t take omega-3 (aka fish oil) supplements. Fish oil supplements require multiple, large pills and daily doses, cause fishy burps and gastric upset, have concerns about quality and rancidity, are typically from squeezed fish, and have mixed scientific findings, with most promising clinical trials limited to pure, pharmaceutical-grade omega-3 (EPA).
The most recent studies support that fatty15 provides better, broader and safer cellular repairing benefits compared to omega-3 (EPA), with just 1 tiny capsule a day*. Additionally fatty is an award-winning C15:0 powder ingredient that is 99% pure, vegan-friendly and stable - in the bottle and your body, without the fishy smell or taste. In addition to the longer term benefits, 2 out of 3 fatty15 customers report feeling benefits within 6 weeks.
Can’t I just get more C15:0 by eating foods with C15:0?
While C15:0 is available in trace levels in food, especially whole fat dairy products, there are a few reasons why the pure C15:0 ingredient in fatty15 (FA15) can be even better for your health.
Food-based C15:0 is tied up in complex lipids called triacylglycerides, which we cannot absorb. Because of this, digestive enzymes are needed to break C15:0 down into free fatty acids, which can then be absorbed. In comparison, fatty15 provides ready-to-absorb free fatty acid C15:0.
Foods with healthy C15:0 also contain bad saturated fats. While dairy fat contains trace amounts of C15:0, these foods contain much higher levels of ‘bad’ even-chain saturated fats (like, C16:0), which come with increased calories and continue to be linked to increased risks of type 2 diabetes and heart disease. Fatty15 was made to provide only the good C15:0 fat - and only 1 calorie.
Our most common food source of C15:0 is dairy fat, which comes from animals. In comparison, the pure and award-winning C15:0 ingredient in fatty15 is vegan–friendly and has no fillers and no additives.
In addition to all of the reasons above, only our pure C15:0 ingredient in fatty15 has been extensively studied for safety and efficacy, including a recent study demonstrating the many cellular benefits of fatty15.
