What NeoAXT™ Does For You
Transmembrane Antioxidant Protection
Astaxanthin’s unique molecular geometry allows it to span the full lipid bilayer — intercepting singlet oxygen and lipid peroxyl radicals anywhere in the membrane cross-section, a structural advantage no other carotenoid possesses.
550x More Potent Than Vitamin E (In Vitro)
In vitro singlet oxygen quenching assays show astaxanthin quenches singlet oxygen approximately 550 times more potently than vitamin E — using physical energy transfer that doesn’t generate secondary reactive species.
Cognitive Protection
A randomized, placebo-controlled trial (n=96) demonstrated cognitive improvements with astaxanthin supplementation at 6–12 mg/day over 12 weeks in healthy middle-aged and elderly adults.
Nrf2 Endogenous Antioxidant Upregulation
Beyond direct free radical quenching, astaxanthin activates the Nrf2/ARE transcriptional pathway — inducing endogenous antioxidant enzymes (HO-1, NQO1, GPx) that amplify overnight enzymatic defense.
Fermentation-Derived Correct Stereoisomer
NeoAXT™ uses Phaffia rhodozyma yeast fermentation to produce astaxanthin.
The Membrane Oxidation Problem
Mitochondrial membranes are the most oxidatively stressed lipid structures in the body. The inner mitochondrial membrane generates 90% of cellular ROS as a byproduct of electron transport — and the polyunsaturated fatty acids that give membranes their critical fluidity are the most vulnerable targets of lipid peroxidation.
Mitochondrial Membrane Peroxidation
Superoxide and singlet oxygen generated by the ETC initiate lipid peroxidation chain reactions in the inner mitochondrial membrane. Each initiation event can destroy dozens of phospholipid molecules before termination. Progressive membrane peroxidation reduces membrane fluidity, impairs Complex I–IV function, and ultimately triggers mitochondrial apoptosis.
Exercise-Induced Oxidative Damage
High-intensity exercise increases mitochondrial ROS production 10–20-fold above baseline. The resulting oxidative stress damages mitochondrial membranes, muscle cell membranes, and circulating lipoproteins — creating an overnight repair burden that exceeds standard antioxidant capacity.
Tissue Repair Without Membrane Protection
Overnight tissue repair requires synthesis of new cell membranes and organelle membranes. If the lipid environment in which this repair occurs is already oxidized, newly synthesized membranes are immediately vulnerable to peroxidation before they can be fully integrated. Membrane protection must precede and accompany structural repair.
How NeoAXT™ Works
NeoAXT™’s astaxanthin has a unique molecular geometry: a rigid conjugated polyene backbone with polar keto-hydroxyl end groups that anchor it in both the hydrophilic and hydrophobic layers of the lipid bilayer simultaneously. This transmembrane positioning distinguishes astaxanthin from all other carotenoids and gives it antioxidant capabilities that cannot be replicated by any other lipid-soluble antioxidant.
Absorption and Membrane Integration
Astaxanthin is absorbed in the small intestine via passive diffusion into chylomicrons, then distributed to tissues via the lymphatic system. Its keto-hydroxyl end groups are highly polar, causing astaxanthin to orient perpendicularly across lipid bilayers with each end anchored in the aqueous phase — a transmembrane orientation unique among carotenoids.
Transmembrane Spanning: Physical Antioxidant Barrier
Beta-carotene and lycopene localize to the hydrophobic interior of membranes. Astaxanthin spans the full bilayer thickness, with polar end groups protruding into the aqueous phase on both sides. This positions astaxanthin to intercept singlet oxygen and lipid peroxyl radicals anywhere in the membrane cross-section — not just the interior.
Singlet Oxygen Quenching: 550x More Potent Than Vitamin E (In Vitro)
In vitro singlet oxygen quenching assays show astaxanthin quenches singlet oxygen (¹O₂) via physical energy transfer (type I quenching) with a rate constant of ~10¹¹ M⁻¹s⁻¹ — approximately 550 times more potent than vitamin E in vitro (singlet oxygen quenching assay). In membrane-phase singlet oxygen quenching assays, astaxanthin is approximately 6,000x more active than vitamin C — though vitamin C operates primarily in the aqueous phase, making direct comparisons limited. The excited astaxanthin molecule dissipates the energy as heat, returning to ground state without generating secondary reactive species.
Nrf2 Activation: Endogenous Antioxidant Upregulation
Astaxanthin activates the Nrf2/ARE pathway by disrupting the Keap1-Nrf2 interaction, allowing Nrf2 to translocate to the nucleus and upregulate endogenous antioxidant enzyme expression — including HO-1, NQO1, GPx, and GR. This transcriptional effect amplifies the direct antioxidant capacity of astaxanthin by inducing a broader cellular antioxidant response.
NF-κB Inhibition: Anti-Inflammatory Mechanism
Astaxanthin inhibits IKKβ-mediated phosphorylation of IκBα, preventing NF-κB nuclear translocation and downstream expression of pro-inflammatory cytokines (TNF-α, IL-6, IL-1β). This anti-inflammatory mechanism reduces the inflammatory component of exercise-induced tissue damage and supports a pro-repair overnight environment.
What the Research Shows
NeoAXT™’s astaxanthin is backed by clinical trials demonstrating cognitive protection, reduction in exercise-induced oxidative biomarkers, and memory improvements — spanning doses from 6–12 mg/day across multiple populations.

Your Daily Dose in RESET
Why this dose works: 10 mg of NeoAXT™ sits at the upper end of the dose range studied in clinical trials, consistent with the 8–12 mg doses showing the strongest outcomes in cognitive and oxidative stress research. NeoAXT™ uses Phaffia rhodozyma fermentation to produce astaxanthin. This is distinct from synthetic astaxanthin, which is a racemic mixture of stereoisomers with different pharmacokinetics.
How NeoAXT™ Connects Across the System
NeoAXT™’s membrane-spanning antioxidant mechanism creates synergies that no other RESET ingredient can replicate. Its unique transmembrane positioning makes it the structural backbone of RESET’s layered antioxidant defense.
Dual Mitochondrial Membrane Protection
Ubiqsome® CoQ10 (ubiquinol form) operates in the hydrophobic interior of the mitochondrial inner membrane as a mobile antioxidant. NeoAXT™ spans the full bilayer, anchoring in both leaflets simultaneously. Together, they provide both mobile interior protection (CoQ10) and anchored transmembrane protection (astaxanthin) — covering the entire cross-sectional area of the membrane.
Compartmentalized Antioxidant Coverage
NeoAXT™ defends lipid membrane phases. Selenium (GPx1) and TrxR defend the aqueous mitochondrial matrix against hydrogen peroxide and lipid hydroperoxides. These compartments are chemically distinct and physically separate — NeoAXT™ and selenium cover different phases simultaneously, not the same one.
DHA Bodyguard
AvailOm® DHA is incorporated into cell and mitochondrial membranes to maintain fluidity, but DHA’s highly unsaturated structure (6 double bonds) makes it the most peroxidation-vulnerable fatty acid in the membrane. NeoAXT™’s transmembrane position directly protects DHA from lipid peroxyl radical chain reactions — acting as a structural guardian for the membrane component that RESET is specifically trying to deposit.
Circadian Mitochondrial Antioxidant Relay
APEX’s SalidroPURE™ activates Nrf2 and AMPK during waking hours, inducing mitochondrial biogenesis and upregulating endogenous antioxidant enzymes. NeoAXT™ also activates Nrf2 — extending Nrf2-driven antioxidant enzyme expression into overnight hours through RESET. The circadian Nrf2 activation signal, initiated by APEX and continued by RESET, maintains elevated endogenous antioxidant capacity around the clock.
Build and Protect
APEX’s Magtein®, CognatiQ®, and Sabroxy® drive BDNF upregulation and synaptic density increases during the day — creating new neural structures that require new membrane synthesis. NeoAXT™ in RESET protects those newly synthesized neuronal membranes from lipid peroxidation overnight, preserving the structural gains made by APEX’s cognitive stack.
Complementary Carotenoid Tissue Targeting
Astaxanthin (NeoAXT™ in RESET) preferentially accumulates in mitochondria-rich tissues: muscle, heart, and brain. Lutein and zeaxanthin (if included in APEX) preferentially accumulate in the macula. These carotenoids target different tissues and provide complementary coverage — astaxanthin for systemic mitochondrial membranes, macular carotenoids for ocular tissue specifically.
Key Takeaways
The Only Carotenoid That Spans the Full Membrane
Astaxanthin’s unique polar keto-hydroxyl end groups cause it to orient perpendicularly across lipid bilayers, with each end anchored in the aqueous phase. This transmembrane position allows it to quench singlet oxygen and lipid peroxyl radicals anywhere in the membrane cross-section — a structural antioxidant advantage no other carotenoid or lipid-soluble antioxidant possesses.
550x More Potent Than Vitamin E in Vitro (Singlet Oxygen Quenching)
In vitro singlet oxygen quenching assays show astaxanthin quenches singlet oxygen at a rate approximately 550 times greater than vitamin E (alpha-tocopherol). This is not a marginal potency difference — it reflects a fundamentally different quenching mechanism (physical energy transfer vs. chemical reaction) that is both faster and does not generate secondary reactive species. Note: in vivo potency ratios may differ.
Fermentation-Derived for the Correct Stereoisomer
NeoAXT™ uses Phaffia rhodozyma fermentation to produce astaxanthin. Synthetic astaxanthin is a racemic mixture with different bioavailability and potentially different biological activity.
Activates Nrf2 for Lasting Endogenous Antioxidant Upregulation
Beyond direct free radical quenching, astaxanthin activates the Nrf2/ARE transcriptional pathway, inducing endogenous antioxidant enzymes including HO-1, NQO1, and GPx. This transcriptional effect extends astaxanthin’s antioxidant impact beyond its direct quenching capacity, amplifying RESET’s overnight enzymatic antioxidant defense.
