A highly transparent and comprehensive pre-workout from NutraBio, delivering effective doses of key muscle-building ingredients and a broad spectrum of performance enhancers, though some pump and endurance ingredients are slightly underdosed per serving.
Extreme Nitric Stack Kiwi Strawberry from NutraBio is formulated as an all-encompassing pre-workout and nitric oxide booster. Its key strength lies in its transparent labeling, allowing consumers to see the exact dosage of each ingredient, fostering trust and informed decision-making. The product includes 3.5g of combined creatine (PharmaPure Creatine Monohydrate and Creatine MagnaPower), which is an effective dose for strength and muscle gain. The 2.5g of L-Leucine is a robust amount for stimulating muscle protein synthesis. AAKG (3.5g) and L-Citrulline (1g) are included for nitric oxide production, though the L-Citrulline dose is on the lower side for optimal pump effects. Beta-Alanine (1.6g) is present for endurance, but typically 3.2g is recommended daily for full benefits. L-Glutamine (4g) and Taurine (2g) further support recovery and hydration. This diverse profile positions it as a versatile supplement for serious training.
- Fully transparent label with no proprietary blends, clearly showing all ingredient dosages.
- Contains clinically effective doses of creatine (3.5g total) for strength and muscle growth.
- Includes a good dose of L-Leucine (2.5g) for muscle protein synthesis.
- Offers a comprehensive blend of ingredients supporting multiple goals: strength, endurance, pump, and recovery.
- Reputable brand known for quality control and third-party testing.
- L-Citrulline (1g) is significantly underdosed for optimal nitric oxide boosting effects; research suggests 3-6g for performance.
- Beta-Alanine (1.6g) is half the commonly recommended daily dose (3.2g) for full endurance benefits, potentially requiring two servings for peak efficacy.
- Higher price per serving compared to some basic pre-workout alternatives, although justified by the ingredient profile.
- Users may experience paresthesia (tingling sensation) due to Beta-Alanine, which is harmless but can be uncomfortable.
- Consult a healthcare professional before use if you have any pre-existing medical conditions or are taking any medications.
- Do not exceed the recommended dosage, as higher amounts may lead to adverse effects.

Categories
Arginine Alpha Ketoglutarate 85.0
The product contains a substantial 3.5g of AAKG, which is a good dose for promoting nitric oxide production and enhancing blood flow. This concentration is higher than many pre-workout alternatives like the C4 line that typically offer 1g of AAKG.
Goals
Muscle Gain 90.0
With an excellent 3.5g dose of creatine and a substantial 2.5g of L-Leucine, this supplement directly supports muscle protein synthesis and strength, which are fundamental for muscle gain. The inclusion of L-Glutamine also aids in post-workout recovery, indirectly contributing to muscle anabolism.
Fitness 88.0
The product provides a well-rounded combination of ingredients that contribute to overall fitness, including strength (creatine), endurance (beta-alanine, though slightly underdosed), and recovery (glutamine, leucine, taurine). This comprehensive approach supports improved workout performance and capacity across various fitness activities.
Cardiovascular Support 75.0
The inclusion of AAKG (3.5g) and L-Citrulline (1g) aims to enhance nitric oxide production, which can improve blood flow and oxygen delivery during exercise, benefiting cardiovascular performance. Taurine also plays a role in heart health. However, the L-Citrulline dose is on the lower end for significant vasodilation and pump, which limits its maximal impact on cardiovascular support in comparison to products with higher citrulline content.
