Next-Generation Nitric Oxide Capsules with Shoden® and N.O.V8™

Bucked Up has constructed a severe status within the pre-workout house, however a devoted pump tablet has been a niche of their lineup. This class is an possibility for athletes who wish to stack stimulant-free circulation help on high of their current pre-workout, or simply need one thing clear to tackle off days to help the cardiovascular system. Bucked Up Circulate fills that hole, and it goes effectively past the usual citrulline method.

Even higher, that is an experiential feel-good method that does greater than enhance blood circulate. The method anchors itself with Shoden®, Arjuna Pure’s patented ashwagandha extract standardized to 35% withanolide glycosides, the highest-concentration kind in the marketplace. We have coated Shoden in depth in our Shoden ingredient deep dive and the Arjuna Naturals podcast on Episode #171, and it is genuinely among the many most enjoyable adaptogen improvements of the previous a number of years.

Alongside it, Circulate introduces N.O.V8™, a fermented nitric oxide metabolite matrix that approaches vasodilation from a special angle than something Bucked Up has run earlier than. This implies it helps stability wholesome blood stress and vascular advantages whereas supporting adrenal glands and combating adrenal fatigue in an over-caffeinated pre-workout atmosphere.

Six substances, two capsules, zero stimulants. The total breakdown is under, however first, examine costs and availability and join our Arjuna Pure information alerts:

Bucked Up Circulate Elements

Shoden® Ashwagandha (Withania somnifera) – 60mg

Shoden® is a superb means so as to add a singular expertise to a class that is lacked innovation for the previous decade. Arjuna Pure standardizes this extract to 35% withanolide glycosides by HPLC, the very best focus of any industrial ashwagandha kind, effectively past its major rivals (5-10%) by a severe margin. That hole issues greater than it would first seem:

Why Standardization Modifications the Math

A 2023 pharmacokinetics crossover trial immediately in contrast WS-35 (the withanolide glycoside-dominant extract underlying Shoden) in opposition to a standard 2.5% withanolide extract at matched whole withanolide doses. WS-35 confirmed a 280-fold greater space underneath the plasma focus curve, together with greater peak plasma ranges and longer imply residence time.[1] That is why Shoden achieves scientific outcomes at 60mg to 120mg the place most different extracts want 300mg to 600mg to method comparable outcomes.

The Mechanism Behind a Pump Product

In a circulation-focused method, ashwagandha earns its spot by way of the hypothalamic-pituitary-adrenal (HPA) axis. Chronically elevated cortisol raises blood stress and promotes vasoconstriction, working immediately in opposition to the vasodilation objectives of the remainder of this stack. Shoden helps help wholesome HPA axis operate, which in flip helps the vascular atmosphere the place the opposite substances can function most successfully.

A 60-day randomized managed trial in wholesome adults with excessive stress discovered that 60mg and 120mg of Shoden decreased morning serum cortisol by roughly 66% and 67%, respectively, versus negligible change within the placebo group.[2] A separate 60-day placebo-controlled research utilizing 240mg Shoden discovered vital reductions on the Hamilton Anxiousness Score Scale alongside considerably decrease morning cortisol, with researchers pointing to HPA axis modulation because the doubtless mechanism.[3]

Shoden brings a brand new period to ashwagandha dietary supplements with 35% glycowithanolide standardization. Analysis exhibits it delivers highly effective results at simply 60-120mg each day, in comparison with 600mg+ with conventional extracts.

Studied to Assist Sleep

Sleep high quality provides one other layer. A six-week trial at 120mg Shoden in adults with non-restorative sleep discovered a 72% enchancment in self-reported sleep high quality alongside vital positive aspects in sleep effectivity and whole sleep time in comparison with placebo.[4] Higher restoration sleep helps the hormonal and cardiovascular atmosphere the place coaching diversifications accumulate between periods.

This makes it the proper ingredient so as to add to a stimulant-free stack. Whether or not you are stacking it with a bunch of stimulants and have to take the cortisol edge off a bit, otherwise you’re on a stimulant break and have to reset your adrenals, Shoden might help.

At 60mg, Shoden sits inside the studied vary, with its distinctive bioavailability profile justifying that effectivity. For the total scientific image, take a look at our Shoden ingredient deep dive.

L-Theanine – 200mg

L-Theanine is a non-protein amino acid from inexperienced tea that promotes alpha-wave exercise within the mind, the frequency vary related to a relaxed, alert psychological state with out sedation.[5] It modulates glutamate and GABA receptor exercise, supporting a relaxed-but-focused neurological state that is distinct from sedatives or stimulants.[6] At 200mg, this matches doses studied in randomized managed trials demonstrating enhancements in sleep high quality, verbal fluency, and government operate after 4 weeks of each day use.[7] A scientific evaluation discovered that 200mg to 400mg/day might assist help wholesome stress administration in adults underneath annoying situations.[8]

In Circulate, L-theanine enhances Shoden’s HPA axis help and Rhodiola’s acute anti-fatigue exercise. The place these adaptogens tackle physiological stress load, L-theanine provides a cognitive dimension, serving to help psychological readability and attentional focus throughout coaching with out stimulants.

Additionally be aware that if you happen to’re stacking Circulate with a Bucked Up pre-workout, you will get the well-studied synergistic results that theanine has with caffeine.[9][10]

Rhodiola Extract (Rhodiola rosea) – 100mg

Rhodiola rosea at 100mg, standardized to three% rosavins and 1% salidroside, matches the energetic compound ratios used within the most-cited scientific analysis on this adaptogen. Generic extracts with no label spec can fluctuate broadly in efficiency, so the express 3:1 rosavin-to-salidroside ratio is a significant high quality sign.[11]

Rhodiola’s major mechanism runs by way of the sympatho-adrenal system (SAS), the pathway governing your acute stress response. A single dose might produce a stimulating impact inside half-hour that lasts 4 to six hours, with out the habit, tolerance, or rebound related to typical stimulants.[12] That is a direct complement to Shoden’s longer-term HPA axis help: one adaptogen overlaying the acute stress response, the opposite the power, giving Circulate’s adaptogen stack two distinct, non-overlapping mechanisms.[13] Rhodiola additionally delivers profit with constant each day use, which makes it a pure match for a method you will tackle coaching and relaxation days alike.

Now it is time to get into some pumps:

Grape Seed Extract (Vitis vinifera) – 100mg

Grape Seed Extract (GSE), standardized to 95% proanthocyanidins (OPCs), kicks off the blood circulate a part of the method with endothelial help that works alongside N.O.V8™ from a special mechanistic angle.

GSE polyphenols activate the PI3K/Akt signaling pathway in endothelial cells, triggering phosphorylation of eNOS (endothelial nitric oxide synthase) and producing a dose-dependent vascular leisure.[14] The place N.O.V8™ delivers pre-formed nitrite to sidestep NOS dependence (mentioned under), GSE reinforces eNOS exercise upstream whereas defending the vascular tissue eNOS depends upon from oxidized LDL and lipid peroxidation stress.[15]

The blood stress knowledge are constant throughout a number of meta-analyses. A 16-trial meta-analysis discovered vital reductions in each systolic and diastolic blood stress with GSE supplementation.[16] In athletes, 14 days of GSE supplementation improved flow-mediated dilation and prolonged time to exhaustion on a progressive biking take a look at — results the researchers attributed partially to enhanced endothelial operate in energetic skeletal muscle.[17]

The 100mg dose at 95% OPC standardization is according to dosages throughout the reviewed trials, making this a tightly dosed end to the method’s cardiovascular stack.

N.O.V8™ (Fermented Botanical Mix) – 20mg

N.O.V8™ is the breakout blood circulate ingredient right here in Bucked Up Circulate. It combines fermented lettuce, fermented cabbage, and fermented garlic powders right into a stabilized nitric oxide metabolite matrix.

The mechanism differs from typical NO substances. Citrulline, beet root, and arginine all require nitric oxide synthase (NOS) enzymes to generate NO, and NOS exercise declines roughly 50% after age 40.[18] N.O.V8™ delivers pre-formed nitrite, a downstream NO metabolite that prompts within the abdomen with out enzymatic conversion, utilizing the sGC-cGMP-PKG pathway to help vascular leisure.[19] A randomized managed trial in wholesome adults discovered that fermented garlic extract containing NO metabolites produced vital will increase in carotid artery blood circulate and regional cerebral blood circulate.[20]

The acute timeline can be price noting: A 2025 observational research in hypertension sufferers discovered {that a} single oral dose of fermented garlic extract containing NO produced vital reductions in each systolic and diastolic blood stress inside quarter-hour, together with measurable enhancements in arterial stiffness markers together with the radial augmentation index.[21] That fast onset makes N.O.V8™ a pure match for pre-workout timing. The fermented lettuce and cabbage parts broaden the nitrite pool past garlic alone, with fermented lettuce extract additionally proven to help a wholesome inflammatory response in preclinical fashions.[22]

At 20mg, the dose appears small by pre-workout requirements, however do not forget that that is nitrate, not citrulline or nitrate, and the low dose required works completely within the capsule format. N.O.V8™ additionally pairs effectively with Shoden right here: Shoden addresses the hormonal aspect of vascular well being by way of cortisol regulation, whereas N.O.V8™ handles direct vasodilation by way of a complementary, enzyme-independent route.

Pyrroloquinoline Quinone (PQQ) – 20mg

Rounding it out, PQQ (pyrroloquinoline quinone) is a redox-active quinone that helps mitochondrial well being by selling mitochondrial biogenesis through PGC-1α activation and biking by way of antioxidant reactions with out degrading.[23][24] A 2023 research additional demonstrated that PQQ drives ATP synthesis immediately, growing ATP content material in neural tissue each in vitro and in vivo.[25]

In human trials utilizing 20mg each day, researchers measured will increase in prefrontal cortex blood circulate and oxygen metabolism alongside enhancements in reminiscence and cognitive flexibility.[26][27] Supplementation at that dose additionally decreased C-reactive protein and IL-6 in a crossover research, according to supporting a wholesome inflammatory response in metabolically energetic tissue.[24]

The 20mg dose in Circulate matches the scientific customary. PQQ’s mobile vitality help and neuroprotective antioxidant exercise layer naturally with the cognitive work L-theanine and Rhodiola do elsewhere within the method.

Easy methods to Use Bucked Up Circulate

Take two capsules each day with meals and 6 to eight oz of water. Circulate has no stimulants, so timing is versatile. Pre-workout use stacks it cleanly along with your efficiency substances. For the adaptogens (Shoden and Rhodiola) to ship their full profit, constant each day use at a daily time is good, together with on off days.
