Key Benefits

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 Problem

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.

Mechanism of Action

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.

01

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.

02

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.

03

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.

04

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.

05

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.

Formula Synergy

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.

RESET

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.

RESET

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.

RESET

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.

RESET → APEX

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.

RESET → APEX

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.

RESET → APEX

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.

Summary

Key Takeaways

01

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.

02

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.

03

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.

04

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.

FAQ

Frequently Asked Questions

NeoAXT™ is a fermented astaxanthin produced via Phaffia rhodozyma yeast fermentation. Astaxanthin is a keto-carotenoid and among the most potent lipid-soluble antioxidants measured in vitro — with a unique molecular structure that allows it to span the full thickness of cell membranes, providing transmembrane antioxidant protection.

How is astaxanthin different from other antioxidants?

Unlike beta-carotene, lycopene, or vitamin E (which localize to the membrane interior), astaxanthin’s polar end groups anchor it in both leaflets of the lipid bilayer simultaneously. This transmembrane position lets it intercept free radicals anywhere in the membrane — and in vitro singlet oxygen quenching assays show it quenches singlet oxygen approximately 550 times more potently than vitamin E.

What does the clinical research show for astaxanthin?

A double-blind, placebo-controlled trial (Katagiri et al., 2012, n=96) showed cognitive improvements at 6–12 mg/day over 12 weeks. A separate RCT (Djordjevic et al., 2012, n=32) demonstrated 40% reduction in the lipid peroxidation marker MDA in soccer players after 90 days of 8 mg/day supplementation.

Why fermented astaxanthin vs. synthetic?

NeoAXT™ uses Phaffia rhodozyma fermentation to produce astaxanthin. Synthetic astaxanthin is a racemic mixture of stereoisomers with different bioavailability and potentially different biological activity.

How does astaxanthin support overnight recovery?

During sleep, the body repairs exercise-induced tissue damage and synthesizes new cell membranes. Astaxanthin protects both existing and newly synthesized membranes from lipid peroxidation, while its Nrf2 activation upregulates endogenous antioxidant enzymes — extending antioxidant defense through overnight hours.

How much astaxanthin is in RESET?

RESET delivers 10 mg of NeoAXT™ fermented astaxanthin per serving — within the upper range of doses studied in clinical trials (4–12 mg/day). This dose is consistent with the amounts showing the strongest cognitive and antioxidant outcomes in published research.
