C4 Sport Energy Blend

Q: What should I do if I'm sensitive to caffeine?

If you are sensitive to caffeine, start with a lower dose of C4 Sport Energy Blend and monitor your response. You can also opt for a caffeine-free version of the product.

Q: Is the tingling sensation from beta-alanine harmful?

No, the tingling sensation (paresthesia) from beta-alanine is temporary and harmless. It is a common side effect and typically subsides within a short period.

Q: When is the best time to take C4 Sport Energy Blend?

It is best taken 30-60 minutes before exercise to allow for peak plasma levels of the ingredients, maximizing their effects during your workout.

Q: Will I see immediate strength gains from taking this product?

Creatine and other ingredients do not provide immediate strength gains but require consistent supplementation over weeks to months to see noticeable improvements.

Q: Is it safe to take more than the recommended dose?

Taking more than the recommended dose does not necessarily lead to greater benefits and may increase the risk of side effects. Always adhere to the recommended dosage.

Also known as: C4 Sport Energy Blend, Caffeine, Creatine Nitrate (NO3-T), Beta-Alanine, Arginine, Citrulline Malate (CM)

Overview

C4 Sport Energy Blend is a pre-workout supplement designed to enhance athletic performance, increase energy, and delay fatigue. It comprises several key ingredients, each with distinct properties. Caffeine stimulates the central nervous system, increasing alertness and reducing perceived exertion. Creatine Nitrate provides creatine for ATP regeneration and nitrate for vasodilation, improving blood flow. Beta-Alanine increases carnosine levels in muscles, buffering lactic acid and delaying fatigue. Arginine and Citrulline Malate are involved in nitric oxide production, which aids in blood vessel dilation. These ingredients are commonly found in pre-workout supplements and have been individually studied extensively. The blend aims to synergistically improve muscle endurance, strength, and overall workout experience. While the individual components have robust research backing, the specific blend may have limited dedicated research.

Benefits

The C4 Sport Energy Blend offers several evidence-based benefits primarily for athletes and active individuals. Caffeine enhances muscle strength and endurance, with studies showing a mean effect size of 0.22. Creatine Nitrate increases bench press power and overall strength and power output by 8-14%. Beta-Alanine increases the number of repetitions completed during high-intensity exercise by approximately 6% and delays fatigue. Citrulline Malate also increases repetitions during strength training by about 6%. The combination of these ingredients may synergistically delay muscular fatigue and enhance endurance. Subjective mood and energy levels can also improve due to caffeine and other stimulants, enhancing the overall workout experience. Benefits from caffeine, beta-alanine, and citrulline malate can be observed within 30-60 minutes of ingestion, while long-term supplementation with creatine and beta-alanine can lead to sustained improvements in strength, power, and endurance over several weeks to months.

How it works

C4 Sport Energy Blend works through multiple mechanisms. Caffeine blocks adenosine receptors in the brain, increasing alertness and energy, and enhances calcium release in muscles. Creatine Nitrate provides creatine for ATP regeneration and nitrate for vasodilation, improving blood flow and oxygen delivery. Beta-Alanine increases carnosine levels in muscles, buffering lactic acid and delaying fatigue. Arginine and Citrulline Malate are involved in nitric oxide production, which aids in blood vessel dilation. These ingredients interact with the muscular, cardiovascular, and nervous systems. Caffeine targets adenosine receptors and the sarcoplasmic reticulum. Beta-alanine is a precursor for carnosine synthesis, and arginine and citrulline malate are involved in nitric oxide synthesis. Caffeine is rapidly absorbed, while creatine and beta-alanine are well-absorbed, and citrulline malate shows better bioavailability than arginine alone.

Side effects

While generally considered safe when used as directed, C4 Sport Energy Blend can cause several side effects. Common side effects (>5%) include jitters, anxiety, insomnia, and increased heart rate from caffeine, and paresthesia (tingling sensation) from beta-alanine. Uncommon side effects (1-5%) include gastrointestinal issues such as nausea, diarrhea, and stomach cramps, particularly with high doses of citrulline malate or arginine, and rarely, muscle cramps. Rare side effects (<1%) include allergic reactions and severe gastrointestinal issues. Caffeine interacts with certain medications such as antidepressants and can exacerbate the effects of other stimulants. Arginine may interact with blood pressure medications. It is contraindicated in pregnancy and lactation, and individuals sensitive to caffeine should avoid or reduce the dose. Athletes should ensure the product is NSF Certified for Sport to avoid banned substances. Children and adolescents are not recommended to use it, and older adults should use it with caution under medical supervision.

Dosage

The recommended dosage for C4 Sport Energy Blend varies depending on the individual ingredients. A minimum effective dose includes 50-100 mg of caffeine, 1 gram of creatine nitrate, 2-4 grams of beta-alanine, 1-2 grams of arginine, and 2-6 grams of citrulline malate. Optimal dosage ranges include 150-300 mg of caffeine, 1-3 grams of creatine nitrate, 2-4 grams of beta-alanine, 1-2 grams of arginine, and 2-6 grams of citrulline malate. The maximum safe dose is 400 mg of caffeine per day, 3 grams of creatine nitrate per day, 6 grams of beta-alanine per day, 9 grams of arginine per day, and 8 grams of citrulline malate per day. It is best taken 30-60 minutes before exercise, mixed with water according to the manufacturer's instructions. Adequate hydration is necessary for optimal absorption, and it can be taken with or without food. Consistent daily dosing may be necessary for some ingredients like creatine to maintain elevated levels.
