Overview of Fatty15

Fatty15 Review

The story of fatty15 begins with one simple mission: to help bottlenose dolphins. Not what you were expecting? As it turns out, the founders didn’t know where their journey would lead.

Founded by partners “in life and purpose,” Stephanie Venn-Watson, DVM, MPH, and Eric Venn-Watson, MD, MBA, the duo originally set out to discover how to continually improve the health and welfare of dolphins, especially as they got older.

Focusing on the health of marine life, they looked at a population of dolphins and sought to determine which nutrients in an all-fish diet predicted the healthiest dolphins. Of all the good nutrients in fish, including omega-3s, they found that the healthiest dolphins had the highest levels of fatty acid C15:0 (aka FA15).

To further determine if C15:0 was beneficial less healthy dolphins were fed fish with higher levels of C15:0. Over time, their aging-related conditions stabilized and their cells did too.

With the knowledge that bottlenose dolphins age a lot like us, Stephanie and Eric were curious to see if C15:0 would be an effective supplement for humans.

By 2021, they had founded and established the company after testing and studying the product for years to ensure it’s safe and effective for humans. The supplement is encapsulated in a vegan-friendly capsule, packaged, and shipped in the US.

While dietary supplements can’t be approved by the FDA, fatty15 is made per the FDA’s current Good Manufacturing Practices (cGMPs), which ensures that the product meets quality and safety standards.

With protecting marine life at its core, the company is also Earth health-conscious. So, all fatty15 supplements come in a refillable glass bottle for the first order and recyclable packaging thereafter to limit the amount of waste with every purchase.

Now that we know a little more about the company and where it started, this fatty15 review will take a look at a few key highlights.

How Does Fatty15 Work?

Fatty15 Review

Fatty15 features one core ingredient: C15:0. This healthy saturated fatty acid can be found in whole-fat dairy products and some plants and fish. It is known to be an essential fatty acid, although our bodies don’t normally produce it.

While it can be found in whole-fat dairy products, these foods also contain much higher levels of bad saturated fats and ingredients that are known to have negative effects. That’s why fatty15 is a single ingredient, formulated to be pure, vegan-friendly, non-dairy, and lactose-free.

The supplement is a simple way to meet your body’s needs, acting as a food and dietary supplement that maintains health. After numerous studies, fatty15 appears to start working in about 1-3 months with daily use, which is why the starter kit has a 90-day supply.

What Are The Ingredients In Fatty15?

Fatty15 Review

The fatty15 supplement is a true example of simple yet effective. So, there is one singular ingredient: pentadecanoic acid (C15:0). Fatty15’s 99% pure C15:0 powder ingredient is called, FA15TM.

To ensure that the supplement comes with the purest vegan-friendly ingredient, it is made entirely from scratch. The powder ingredient exactly matches the form of C15:0 found in nature, so it is considered a natural ingredient.

How To Take Fatty15 And Dosage

Fatty15 Review

When it comes to taking the fatty15 supplement, the entire process is designed to be as simple as the ingredient list. Here’s how it works for you first-timers:

  1. Open the packaging
  2. Pour the supplements into the reusable glass bottle (keep the bottle for the future)
  3. For future orders, you will receive refill pouches delivered to your door and the capsules can then be poured into your reusable glass bottle

When it comes to ingesting the supplement, simply take 1. Good fats are best absorbed when ingested along with other foods, so you may want to take them with a meal. The company suggests taking your supplement in the morning to create a routine.

Fatty15 Side Effects

Fatty15 Review

If you’re considering adding a supplement to your diet, one of the most important things to consider is the potential side effects. Fortunately, this fatty15 review is happy to share that side effects are rarely reported. This makes sense, since C15:0 is a nutrient in milk (though it’s dairy-free) and has thus been a natural addition to the human diet for centuries.

With over 12,000 customers, very few have reported side effects (less than 0.3%), which have included mild gastrointestinal symptoms, headache, or a temporary skin rash. Similar side effects have been reported with other essential fatty acid supplements.

The ingredient is also has official GRAS (generally recongnized as safe) status, which means fatty15 has been deemed safe for pregnant women and nursing moms.

The supplement is also not known to cause weight gain, which may be a concern for some. In fact, one fatty15 capsule is less than 1 calorie and the product is actually designed to help your cells work more efficiently, using more energy rather than storing it as fat.

If you’re wondering about whether or not you can pair your fatty15 supplement with other vitamins and medications, you can rest easy. The product was designed to compliment your current diet and health regimen, and there have been no contradictions or issues reported with other medications or vitamins thus far.

With all that being said, it’s always important to consult your healthcare provider before adding any supplement to your diet.

Fatty15 Reviews: What Do Customers Think?

Fatty15 Review

While this fatty15 review has established what you’ll find in the supplement and how it’s supposed to work, it’s time to delve deeper into what real customers have experienced.

Since the company was recently founded in 2021, there aren’t too many fatty15 reviews floating around the internet. Regardless, we have sourced comments from the brand’s website, The Quality Edit, and Thing Testing to paint an accurate picture of the effects of the supplement.

The company has 330 verified customer reviews and boasts 4.7 out of 5 reviews on its website. One customer reports feeling younger and looking better, and that the supplements also help them maintain a healthy diet. Take this excerpt:

I am 57 years old. I was already looking good for my age, but I am looking even better and more importantly, feeling 10+ years younger! I sleep well, wake up refreshed, and am able to handle stress better. I’m not as interested in eating things that are not on my Keto plan and my joints aren’t hurting anymore. What’s not to love?!

Another patron shared fast-acting results, writing, “After 45 days, I felt more calm and lost 10 lbs without much of an effort. I don’t know if everyone will have the same outcome but for me it improved my life in noticeable ways. I have already recommended Fatty15 to my friends.

A reviewer on Thing Testing awards the company 5/5 stars, writing about their subtle yet noticeable results with an increase in energy and mood. Here’s what they had to say:

After taking it for about 2 months now, I can say that while the effects are very subtle I have noticed a definite increase in energy (especially in the morning). I felt like this has improved my mood throughout the day as well. I am going to continue to take these everyday and am excited to see more results!

Another buyer shares similar sentiments, also awarding the brand 5/5 stars:

After taking the product for 4 weeks, I have noticed that I don’t snack as much, can last longer in my “intermittent fast” although I’m not always looking to do it, and my hunger pangs are much better controlled. They also tout that it improves your mood, increases your energy, and my help with aging/feeling younger. I can say that my energy levels are bit increased.

On The Quality Edit, the reviewer writes that the brand is worth checking out because it is “the world’s first, and only, supplement with C15:0, fatty15 is transforming the game of preventative health and well-being.

The sustainable packaging also stands out: “Fatty15 ships with a reusable glass bottle, 100% recycled and recyclable packaging, and a bamboo top — so you can do well for both your body and the earth.

Overall, it looks like fatty15 offers nothing but good things. With very minimal side effects reported and plenty of benefits to show, the supplement truly seems to be an effective option to combat aging and maintain a healthy body and lifestyle.

Hi, I’m Paige and I’m a product tester at Honest Brand Reviews.

Fatty15 Review 1
Paige, Product Tester

Fatty15 is a really unique supplement. It was super easy to add to my daily routine since it involves taking just one little capsule.

Fatty15 Review

While I’m not vegan, I thought it was cool that the entire formula is vegan-friendly since regular omega-3 supplements usually come from fish.

The science behind the brand is pretty impressive too, and with time, I’m interested in seeing what the benefits are.

Is Fatty15 Worth It?

Fatty15 Review

The fatty15 supplement has been carefully tested and studied to ensure effectiveness. It is known to be an essential fatty acid that can help regulate your immune system and metabolism and is a simple way to upgrade your diet and health.

This study showed over 36 cellular benefits among 83% of cell types that were relevant to immune, gut, heart, joint, lung, and metabolic health.

The company is also backed by many happy customers who claim that the products truly do live up to the hype. There are also very mild side effects in comparison to other supplements on the market and they contain no fillers or artificial flavors and are also vegan-friendly, dairy-free, and gluten-free.
