How is it stimulant free if it contains beta alanine?

Beta-Alanine is not a CNS stimulant.

How long will I feel the effects of this?

Actively feeling focused/energized 45-75 minutes. Subtler, lingering effects take a few hours to taper off.

How is this vegan friendly if it contains milk?

Vegan friendly? I don’t think so. It even contains shellfish.

Is the noolvl propriety component more or less nitric oxide? can we get some more clarity on what this compound is please?

NOOLVLTM COMMON NAME Inositol-enhanced Bonded Arginine Silicate TOP BENEFITS OF NOOLVLTM - Enhances processing speed and accuracy* - Supports executive function* - Boosts energy* - Promotes muscle performance* WHAT IS NOOLVLTM? nooLVLTM is comprised of two components: Bonded (inositol-stabilized) arginine silicate (Nitrosigine®) plus additional inositol. L-arginine has relatively low bioavailability (~20%) following an oral dose, so high doses are needed to significantly boost blood arginine levels.[1] Nitrosigine® and nooLVLTM have overcome this limitation by bonding the L-arginine to a silicate–inositol complex, which significantly enhances the bioavailability of L-arginine.[2–5] L-arginine is involved in promoting healthy circulation because it can be used for nitric oxide production. Blood flow to metabolically active tissues, like the brain and muscles, plays a big role in allowing these tissues to perform their functions at a high level. Bonded arginine silicate supports exercise performance and post-exercise recovery by promoting muscle blood flow.[6] It also supports brain performance, enhancing mental accuracy, focus, processing speed, and executive function.[5,7,8] nooLVLTM has been clinically studied in humans: It has boosted cognitive performance and energy in eSports athletes. nooLVLTM is an upgraded version of Nitrosigine®, an ingredient that supports blood arginine levels and nitric oxide production, enhanced energy, promoted focus and mental acuity, and supported better muscle response following exercise. nooLVLTM is a patented nutritional ingredient from Nutrition 21: It contains Nitrosigine® (l-arginine bonded to silica and inositol with affirmed GRAS) plus added inositol. nooLVLTM is gluten-free, vegan, and non-GMO. nooLVLTM is a trademark of Nutrition 21, LLC. NOOLVLTM DOSING PRINCIPLES AND RATIONALE Studied dose of nooLVLTM has been 1600 mg/day: Nitrosigine® has been 1500 mg/day. Since these are the highest doses that have been given in human research, we consider them to be the upper limit we’d be comfortable with for daily dosing. Since it’s possible that the product this is included in might be used more than once a day (i.e., a person could opt to take two servings), we included a half dose per serving (i.e., 800 mg of nooLVLTM). In Neurohacker’s subjective and objective internal N of 1 testing, the half dose of nooLVLTM had additive effects when combined with other nootropic ingredients.* NOOLVLTM KEY MECHANISMS Vascular function - L-arginine is the substrate for vascular nitric oxide (NO) production by NO synthase (NOS)[9] - Upregulates endothelial NOS (eNOS) [silicate][10] - Upregulates the blood levels of arginine, silicon, and NO[4] - Supports healthy vascular function [2] - Supports healthy blood pressure [arginine][11] [inositol][12,13] Brain function - Upregulates dopamine release[14–16]. - Regulates dopamine transporter (DAT) activity[17–20] - Supports neurotransmitter signaling [inositol][21] Cognitive function - Supports performance in complex cognitive tests requiring mental flexibility, processing speed and executive functioning[7] Exercise performance (ergogenic effects) - Supports exercise performance [arginine][22] - Delays time to exhaustion [arginine][22] - Delays muscle fatigue [arginine][23] - Supports muscle blood flow after exercise[6] - Protects from muscle damage after exercise and during recovery[6]
