Core SEAR: Enhance Your Body Composition Without Stimulants

Losing body fat can be extremely challenging, but there are several tools that can make the process a lot easier. If you’re serious about this, one of the first things to know is that you need to create a caloric deficit. That means burning more calories than you consume. When you’re in a caloric deficit, the body is forced to rely on fat stores —rather than food— for energy,

If you want to be as shredded as Core Nutritionals athlete, Jay Brew, then a caloric deficit is required.

Gradually, body fat levels will decline.

At the same time, if you consume a sufficient amount of protein (~1 gram per pound of body weight) and continue to train, you should retain muscle while losing fat. This will result in overall improved body composition (i.e. lower percentage of body fat with a higher percentage of lean muscle mass). Although being in a calorie deficit and exercising regularly is necessary for weight loss, taking supplements, like fat burners or thermogenics, may help speed up the process.

Most fat burners and thermogenics on the market typically contain a stimulant, such as caffeine. Most people know the fast-acting ingredient is extremely safe and effective at increasing energy levels, metabolism, and suppressing hunger. The only downside to a fat burner containing caffeine is that you can really only take it in the morning or early afternoon since consuming a stimulant later in the day can negatively affect your sleep quality.

There are other reasons to be reticent about caffeine. It increases levels of cortisol (the body’s primary stress hormone), which could, over time, contribute to a plateau in weight loss. It’s also easy to build up a tolerance for caffeine, so you’ll have to keep taking more to achieve the same results. Countless products contain caffeine, such as pre-workouts, energy drinks, nootropics, coffee, and soda, so adding a well-formulated caffeine-free fat burner to your supplement regimen can be very useful.

Arguably, one of the most impressive non-stimulant thermogenics on the market is Core Nutritionals SEAR.

Core SEAR: A Potent Non-Stimulant Thermogenic

Core SEAR Graphic

Core SEAR was formulated to help increase the amount of brown adipose tissue and lose fat faster.

Core SEAR is a stimulant-free thermogenic and recomposition agent that’s formulated to:

  • Increase adipocyte conversion from white to brown adipose tissue
  • Optimize metabolism
  • Enhance thermogenesis
  • Improve body composition by reducing body fat levels

To achieve these benefits, Core SEAR uses four key ingredients:

  • Sinetrol XPur from Fytexia
  • MitoBurn from NNB Nutrition
  • Coleus forskholli extract
  • Paradoxine Grains of Paradise

Core SEAR has a simple, yet powerful, combination of ingredients that may help you lose fat faster. One of the key benefits of Core SEAR is that you can stack it with other supplements, such as a stimulant-based pre-workout, without worrying about ingredient overlap. So far, PricePlow has never seen this combination of ingredients in a single product. So obviously our curiosity is piqued.

Core SEAR Ingredient Breakdown

The Core Nutritionals SEAR Ingredients – Excellent and unique stim-free formula here!

For best results, Core Nutritionals recommends taking one serving (three capsules) of Core SEAR before exercise. Since it’s stimulant-free, you can take it any time of the day. If you want to stack Core SEAR with a stimulant-based fat burner, we recommend using Core BURN.

Here’s what one serving (three capsules) of Core SEAR contains:

  • Sinetrol XPur [Blend of Grapefruit (Citrus Paradise)(Fruit), Guarana (Paullinia Cupara Kunth)(seed), Sweet Orange and Blood Orange (Citrus Sinesis L. Osbeck) (Fruit Extracts) – 900mg

    Sinetrol XPur is a patented, proprietary blend of several polyphenolic compounds extracted from Mediterranean citrus fruits, including grapefruit, oranges, and blood oranges.[1,2] Sinetrol is rich in bioactive polyphenols, including naringin, hesperidin, and a compound that contributes to its lipolytic properties, neohesperidin.[1,2]

    While there are several citrus extracts on the market, Sinetrol stands apart from the pack because clinical studies on humans validate claims about its success in the weight loss category.[1-4]

    Based on current scientific literature, Sinetrol may help:

    • Reduce body fat levels
    • Decrease body weight
    • Enhance lipolysis
    • Decrease waist and hip circumference
    • Lower oxidative stress and inflammation[1-4]

    Sinetrol’s primary mechanism of action


    Sinetrol combines a proprietary blend of citrus extracts specifically formulated to help you shed fat.

    Research has demonstrated that Sinetrol’s main mechanism of action is inhibiting phosphodiesterase (PDE). In particular, compounds in Sinetrol inhibit the PDE-4 enzyme.[1-4] Phosphodiesterase inhibitors, such as Sinetrol, boosts levels of cyclic adenosine monophosphate (cAMP) by preventing its breakdown. Since cAMP is a secondary messenger that’s crucial for supporting metabolic processes (including fatty acid metabolism), having sufficient levels is advantageous for achieving fat loss.

    With a unique mechanism of action, Sinetrol may work synergistically with the other ingredients in Core SEAR to help you lose fat more efficiently. Although there’s a good amount of research to support using Sinetrol, we don’t see it in many non-stimulant thermogenics, so we’re excited that Core decided to use it at the clinically-proven dose.

  • MitoBurn (L-ꞵ-Aminoisbutyric Acid)(BAIBA) – 500mg

    Core SEAR is also one of the few non-stimulant fat burners on the market to use MitoBurn, a patented form of L-ꞵ-aminoisbutyric acid (BAIBA) from NNB Nutrition. MitoBurn looks to be the next big thing to enter the health and sports supplement market. Its benefits go beyond fat loss. As a relatively novel ingredient, only a few notable sports nutrition brands have started using it, including Core Nutritionals.


    NNB Nutrition has finally introduced a trusted and tested form of L-BAIBA, which is an “exercise signal” that kickstarts incredible metabolic processes!

    To truly appreciate what MitoBurn has to offer, it’s important to know the difference between the two forms of BAIBA: L-BAIBA and D/R-BABIA.

    L-BAIBA is created from the breakdown of the essential amino acid valine, whereas D/R-BAIBA comes from the breakdown of thymine, a constituent of nucleic acids.[5-8] At first glance, they may not seem that different, but they can actually deliver dramatically different results.

    Due to valine oxidation in skeletal muscle, it’s been demonstrated that the L-BAIBA isomer provides the most beneficial metabolic effects.[5-8] And during bouts of exercise, L-BAIBA is present much more.[5-8] That’s why it’s commonly referred to as “the exercise-induced muscle factor.”

    Although D/R-BAIBA may have some positive effects, to get the most bang for your buck in terms of metabolic enhancement, L-BAIBA is where it’s at. That’s exactly what MitoBurn aims to deliver.

    The Benefits of MitoBurn

    MitoBurn Logo

    MitoBurn from NNB Nutrition has been tested out to be a pure form of BAIBA on the market!

    MitoBurn is technically classified as a myokine, which simply means it’s released from skeletal muscle and carries out effects via cell signaling. Exercise releases increasing amounts of L-BAIBA, which studies have founds causes a chain reaction that results in thermogenesis and fatty acid oxidation.[5-8]

    MitoBurn may also improve insulin sensitivity, glucose tolerance, prevent bone loss, help convert white adipose tissue (stored fat) to brown.[5-8] This is where Core SEAR gets its name. Think about when you sear meat and it turns brown. Core SEAR has several ingredients that help convert white adipose tissue to brown adipose tissue, including MitoBurn, Sinetrol, and grains of paradise. Since brown adipose tissue is more metabolically active, having greater levels is advantageous for achieving weight loss.

  • Coleus Forskohlii Extract (Root) (20% Forskolin) – 250mg

    Coleus forskohlii is a plant that’s native to India. Historically, coleus has been used to treat disorders of the gastrointestinal, respiratory, nervous, and cardiovascular systems.[9] The reason coleus forskohlii is mainly found in weight loss supplements is because researchers discovered the plant may have potent anti-obesity properties.[9-11]

    Core Burn Fire

    Stack Core SEAR with Core BURN for an epic weight loss stack!

    Some studies have shown that coleus forskohlii extract can increase lipolysis by activating an enzyme called adenylate cyclase, which results in further elevated cyclic adenosine monophosphate (cAMP) levels in cells.[9-11] Cyclic adenosine monophosphate is involved in regulating glucose and fatty acid metabolism. Therefore, higher levels of cAMP can increase the breakdown of stored fats in human cells.

    Moreover, cAMP regulates bodily functions like:

    • Thermogenic response to food
    • Basal metabolic rate
    • Utilization of body fat[9-11]

    cAMP may promote the release of fatty acids from adipose tissue, resulting in increased thermogenesis, reduced body fat, and improved body composition.[9-11] Since forskolin, the main bioactive constituent in coleus forskohlii, raises cAMP accumulation, it strongly stimulates lipolysis.[9-11] Other research has shown that coleus can positively affect thyroid function. The thyroid is a gland that plays an important role in metabolism.[9-11]

  • Paradoxine Grains of Paradise (std. to 12.5% 6-Paradol) – 50mg

    To further help convert white adipose tissue to brown, Core SEAR uses 50 milligrams of a trademarked form of grains of paradise (GP), Paradoxine. Grains of paradise is actually a spice that’s related to ginger. They both belong to the Zingiberaceae family of plants. It’s also one of the most popular ingredients in weight loss supplements. Traditionally, GP was used to improve digestion, body composition, and for its antioxidant and anti-diabetic properties.[12,13]

    Paradoxine Logo

    Paradoxine is the premier choice for Grains of Paradise extracts.

    The premier grains of paradise extracts contain four main bioactive constituents (6-paradol, 6-gingerol, 6-shogaol, and 6-gingerdione),[12,13] but Paradoxine has been standardized to just 12.5% 6-paradol, which researchers attribute much of the fat-burning effects to.

    Research shows that supplementing with grains of paradise may:

    • Increase energy expenditure
    • Promote the conversion of white adipose tissue to brown
    • Reduce body fat[12,13]

    As we mentioned earlier, Core SEAR primarily works to turn white adipose tissue brown. Since brown adipose tissue is more metabolically active, taking a higher dose may help you burn more calories; and it may even work when you’re at rest.[12,13]

    You can learn more about Grains of Paradise in our article titled Grains of Paradise: Fat Fighting Spice of the Goddesses, where we also compare other full-spectrum GP extracts and their standardizations.
