Legion Pulse+ Burn Ingredients (16.93 grams per serving)

Caffeine (350 milligrams per serving)

Caffeine is a naturally occurring substance found in many plants native to Africa, East Asia, and South America, including various kinds of tea, cocoa, and coffee.

Caffeine’s primary effects in the body are to stimulate the central nervous system and block the activity of another chemical—adenosine—that causes tiredness.

Research shows that supplementation with caffeine . . .

The clinically effective dose of caffeine for enhancing energy, focus, and performance is between 1 and 6 milligrams per kilogram of body weight.[34][35][36]

Caffeine

L-Theanine (350 milligrams per serving)

L-theanine is an amino acid mainly found in green tea. It supports relaxation and focus by interacting with neurotransmitters like glutamate, GABA, serotonin, and dopamine to lower excitatory brain signals and boost calming ones.

Research shows that supplementation with L-theanine . . .

  • Reduces the effects of mental stress[37]
  • Promotes relaxation[38]
  • Improves mood, memory performance, and attention (when paired with caffeine)[39][40][41][42]

The clinically effective dose of L-theanine when combined with caffeine is between a ratio of 1:1 and 2:1 theanine to caffeine.

L-Theanine

L-Carnitine L-Tartrate (2 grams per serving)

L-carnitine is a naturally occurring amino acid mainly found in meat and dairy. It’s “conditionally essential,” meaning your body can only make it if you’re eating enough lysine and methionine, two amino acids it can’t produce on its own.

L-tartrate is a salt that improves the absorption of other nutrients.

L-carnitine helps your body burn fat more efficiently by shuttling long-chain fatty acids into your cells’ mitochondria, where they’re broken down for energy via a process called β-oxidation.

It also enhances the function of CPT1—the enzyme that controls this process—which may help you burn more fat during exercise, preserve glycogen, and train harder for longer.

Research shows that supplementation with L-carnitine . . .

The clinically effective dose of L-carnitine L-tartrate is 500–2000 milligrams per day.

L-Carnitine L-Tartrate

Capsimax™ Capsaicinoid Extract (100 milligrams per serving)

Capsaicinoids are the group of naturally occurring compounds in chili peppers that give the fruit its signature spicy heat.

Capsimax™ is a patented capsaicinoid extract with a controlled-release coating that delivers an effective dose without the digestive discomfort often associated with capsaicin supplements.

Capsaicinoids support fat burning by decreasing the activity of genes that promote fat storage like PPAR-γ and SCD, while activating ones that boost energy expenditure like PGC1α and PRDM16.

Additionally, capsaicinoids activate TRPV1, a protein that responds to heat and supports fat burning and appetite control.

Research shows that supplementation with capsaicinoids . . .

  • Supports fat burning[57]
  • Supports appetite control[58]
  • Increases strength and strength endurance[59][60][61]
  • Reduces perceived effort during exercise[62][63][64]
  • May enhance cognitive function[65]

The clinically effective dose of capsaicinoids is 2–10 milligrams per day.

Pulse+ Burn contains 100 milligrams of Capsimax™, which provides 2 milligrams of active capsaicinoids.

Capsimax Extract

Grains of Paradise (30 milligrams per serving)

Grains of Paradise is the common name for the plant Aframomum melegueta, which is an herb in the ginger family that’s commonly used as a spice.

It contains compounds like 6-gingerol and 6-paradol that influence receptors on fat cells involved in energy regulation and temperature perception.

That’s why research shows that supplementation with Grains of Paradise increases energy expenditure and supports visceral fat burning.[66][67][68][69]

The clinically effective dose of Grains of Paradise is around 30 milligrams of an extract providing 3–4 milligrams of 6-paradol.

Grains of Paradise

Citrulline Malate (8 grams per serving)

Citrulline malate is a compound consisting of L-citrulline—an amino acid found in foods like watermelon, pumpkin, and cucumber—and malic acid, a naturally occurring component of many fruits and vegetables that supports energy production.

The body converts L-citrulline into the amino acid L-arginine, which increases the production of nitric oxide—a gas that widens blood vessels and improves circulation.[70][71]

Research shows that supplementation with citrulline malate . . .

The clinically effective dose of citrulline malate is between 6 and 8 grams.

Citrulline Malate

Beta-Alanine (3.6 grams per serving)

Beta-alanine is a naturally occurring amino acid that regulates the amount of the molecule carnosine that can be stored in the muscles.[80]

Carnosine reduces muscle acidity, which increases the amount of work that muscles can do before they become fatigued.[81]

Research shows that supplementation with beta-alanine . . .

The clinically effective dose of beta-alanine is between 2.6 and 6.4 grams.

We chose to include 3.6 grams per serving because it provides significant performance benefits while also minimizing the common and harmless side effect of a mild prickling, itching, or tingling of the skin.[97]

Beta-Alanine

Betaine (2.5 grams per serving)

Betaine (or trimethylglycine) is a compound derived from the amino acid glycine and found in foods like beets, spinach, and quinoa.

Betaine has three methyl groups—small chemical units containing one carbon and three hydrogen atoms that your body uses in essential processes like building DNA, breaking down fats, and producing energy.

Betaine's also an osmolyte, which is a substance that helps balance fluid levels inside and outside cells.

These two properties are beneficial during times of physical stress, which is why studies show that supplementation with betaine . . .

  • Boosts muscle endurance[98]
  • Increases strength and power[99]

The clinically effective dose of betaine is between 2 and 4 grams, with most studies using 2.5 grams.[100][101]

Betaine

Naturally Sweetened and Flavored

While artificial sweeteners may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health.[102][103][104][105][106][107]

That’s why we use natural sweeteners like stevia, allulose, and monk fruit instead. Research shows that these ingredients are not only safe but can also confer several health benefits, such as supporting weight management, antioxidant activity, digestive health, and more.[108][109][110][111]

Naturally Sweetened & Flavored

No Artificial Food Dyes, Fillers, or Other Unnecessary Junk

As with artificial sweeteners, studies show that artificial food dyes and fillers can cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[112][113][114][115][116]

That’s why we use natural coloring and flavoring derived from fruits and other foods as well as naturally derived ingredients for improving texture, enhancing shelf life, and facilitating the manufacturing process.

No Artificial Junk
