  • About OptiNAD+ Capsules

    OptiNAD+ combines six carefully selected ingredients to support nicotinamide adenine dinucleotide (NAD+) levels throughout your body. The formula features NMN and nicotinamide riboside alongside NADH, plus synergistic compounds like apigenin and quercetin that help preserve and optimize the NAD+ you produce. OptiNAD+ supports cellular health by supporting mitochondrial energy production and promoting healthy aging processes.

    Our OptiNAD+ Story

    Most NAD+ supplements on the market take a single-ingredient approach, typically offering just NMN or nicotinamide riboside alone. While these individual precursors have merit, we knew there was potential for a more sophisticated strategy. Even high doses of standalone NAD+ precursors often fell short of their potential because they lacked the supporting compounds needed to optimize bioavailability.

    We created a comprehensive NAD+ enhancement stack by combining multiple complementary NAD+ precursors working through different pathways, then adding protective compounds like apigenin and quercetin to support NAD+ preservation, plus trimethylglycine to replenish the methyl groups consumed during NAD+ synthesis. After extensive beta testing with our team, we achieved what we consider the most comprehensive NAD+ enhancement formula we've tested. The difference is immediately noticeable compared to single-ingredient alternatives.

    Benefits

    • Supports Mitochondrial Function: OptiNAD+ supports the powerhouses of your cells by providing multiple NAD+ precursors that support mitochondrial energy production and ATP synthesis.
    • Supports Cellular Energy: The combination of Nicotinamide mononucleotide, nicotinamide riboside, and NADH supports healthy physical and mental vitality.
    • Supports Longevity and Healthspan: By supporting healthy NAD+ levels that naturally decline with age, this formula supports sirtuins and the cellular processes associated with longevity and healthy aging.
    • Supports Healthy Circadian Rhythms: NAD+ plays a crucial role in your body's internal clock, and users often experience progressively better sleep quality as their circadian rhythms become more balanced.

    The apigenin and quercetin in this formula support healthy CD38 activity, while quercetin supports sirtuin activity to maximize the NAD+ benefits you experience from each dose.

    Quality and Standardization

    • Multi-pathway NAD+ support: Our comprehensive formulation combines three distinct NAD+ precursors (NMN, nicotinamide riboside, and NADH) with supportive compounds (apigenin and quercetin) to support bioavailability and healthy NAD+ levels throughout the body.
    • Standardized ingredient potency: Each capsule delivers precise amounts of pharmaceutical-grade compounds, ensuring consistent NAD+ support with every dose while maintaining optimal ratios between precursors and synergistic compounds.
    • Methyl group replenishment: We included trimethylglycine as a highly efficient methyl donor to support the methyl group processes that occur during intensive NAD+ synthesis, supporting sustained cellular health processes.
    • Third-party verified purity: All components undergo rigorous testing for identity, potency, and contaminants to ensure you receive the cleanest, most comprehensive NAD+ enhancement formula we've tested.

    Mechanism of Action

    • NAD+ Salvage Pathway Support: Nicotinamide mononucleotide supports cellular uptake via specialized Slc12a8 transporters, while nicotinamide riboside supports the NRK1/NRK2 kinase pathway for efficient NAD+ synthesis.
    • CD38 Enzyme Support: Apigenin and quercetin support healthy CD38 activity and cellular NAD+ levels in healthy tissues.
    • Direct NADH Support: NADH utilizes specialized mitochondrial shuttles and cytoplasmic reductase systems to support NAD+ levels while supporting electron transport chain efficiency.
    • Sirtuin Pathway Support: Quercetin supports SIRT1 and SIRT3 expression through FOXO transcription factor pathways, supporting healthy NAD+ utilization while promoting cellular stress resilience and metabolic function.
    • Methyl Group Replenishment: Trimethylglycine supplies methyl donors through the betaine-homocysteine methyltransferase pathway, supporting healthy S-adenosylmethionine levels during intensive NAD+ biosynthesis and supporting optimal methylation reactions.

    Overview of the Science

    Clinical trials demonstrate that NAD+ supplementation supports healthy NAD+ levels in healthy adults [1][2]. Studies show that nicotinamide mononucleotide supplementation supports blood NAD+ concentrations by up to 1.7-fold within 12 weeks, with benefits observed for muscle function and arterial health [3][4]. Research suggests nicotinamide riboside safely promotes NAD+ levels by 40-90% in healthy middle-aged and older adults, with sustained elevation throughout chronic supplementation periods [5][6][7]. Studies indicate that combining multiple NAD+ precursors with CD38 inhibitors supports enhanced bioavailability and retention compared to single-ingredient approaches [8].

    The circadian regulation of NAD+ synthesis represents a critical factor in optimizing supplementation timing and efficacy. NAD+ levels naturally fluctuate throughout the day, with peak synthesis occurring during morning hours when energy demands are highest. This rhythmic pattern suggests that morning administration of NAD+ precursors may align with endogenous biosynthetic pathways for maximum utilization. Additionally, caloric restriction and fasting states have been shown to upregulate NAD+ synthetic enzymes, indicating that supplementation during periods of metabolic stress or alongside metabolism support protocols may enhance overall effectiveness.
