Welcome to the family of fatty15 C15:0 supplements,
for the grown up and the growing up.
Fatty15 is a daily healthy aging supplement that strengthens cell membranes against age-related breakdown. It has 36+ cellular activities that support long-term metabolic, cognitive, liver, red blood cell, and immune health.* Fatty15 gummies deliver our pure, science-backed and patented C15:0 ingredient in a sugar-free, high-fiber and delicious form.
Our gummies contain a pure, patented and bioavailable form of C15:0 (pentadecanoic acid). This award-winning C15:0 ingredient is produced in FDA-registered, cGMP-certified facilities and each batch is tested to confirm ≥98% purity. We also use third-party testing to ensure quality and safety before release.
Fatty15 gummies are vegan, gluten-free, lactose-free, dairy-free, sugar-free and soy-free, and made without common allergens, preservatives, artificial colors, or animal byproducts.
Fatty15 gummies are sweetened with Rebaudioside M (Reb M), the next-generation stevia sweetener. Unlike Reb A (the more common stevia ingredient), Reb M has a clean taste more closely resembling (sucrose) sugar, without the bitter aftertaste stevia sometimes gets blamed for. This may be because Reb M binds to sweet taste receptors in a similar way as sucrose! The one thing Reb M and Reb A have in common is that they do not cause a spike in blood glucose.
Cheers to smooth sweetness, no bitterness, and no sugar spike.
The good source of fiber in fatty15 gummies comes from fructooligosaccharides (FOSs) — a mouthful to say, but your gut will thank you. FOSs are short-chained fructose molecules naturally found in some fruits and veggies. Adding some light sweetness, they’re considered a prebiotic fiber because, unlike sugar, they aren’t fully digested by our bodies. Instead, they travel through our digestive system to feed and support a healthy microbiome.
Yes! You can absolutely combine fatty15 gummies with your fatty15 capsules. We recommend not exceeding a total of 300mg per day.
Fatty15 gummies are also safe for kids (ages 4+) and teens, making them a flexible option for families.
Many customers enjoy mixing formats to fit their routine - for example, capsules some days and gummies on others, or a combination of both.
We recommend taking 2 to 4 gummies per day. Each gummy contains 50 mg of C15:0.
Fatty15 Gummies can be taken with or without food, and any time of day.
While fatty15 is for your long-term health, about 70% of 6,243 surveyed customers report feeling near-term benefits, including supported sleep, mood, and energy.* Because some of these near-term benefits may peak 4–6 hours after taking fatty15, many customers prefer taking their gummies in the morning. Others report that taking them in the evening works better for their routine or helps support sleep.*
Bottom line: consistency matters most. You can adjust when you take fatty15 gummies based on what feels best for you.
