Double Wood Supplements offers an extensive range of single-ingredient and targeted formulas designed to support specific fitness needs rather than broad, all-in-one blends. Its product lineup covers multiple fitness categories, including brain health, sleep support, immune function, metabolic health, mood balance, and healthy aging. The brand’s offerings are intended to support common concerns linked to modern lifestyles, such as mental fatigue, stress, low energy, and nutrient gaps.
In this review, we will explore Double Wood Supplements in detail by examining its product range and the types of concerns its formulations aim to address. We will also compare it with similar brands, what users report about their experiences, and how the brand is viewed in terms of brand reputation.
As per the official website, Double Wood Supplements operates within the practitioner-grade space while keeping its products priced for routine, long-term use. The brand provides third-party testing and publishes Certificates of Analysis, allowing verification of ingredient identity and purity. It also highlights that its every product is intended to function independently or be combined with others through the brand’s stack-based system.
Double Wood covers a broad range of product categories that include products for brain and cognitive support, immune function, metabolic balance, liver health, sleep, stress management, and bone and joint support.
The brand’s product lineup covers diverse formats such as capsules, powders, liquid drops, granules, and gummies. These offerings include various forms of magnesium, NMN in capsule and powder form, berberine, tongkat ali, quercetin, collagen peptides, vitamin D3 with K2, phosphatidylserine, CDP choline, nattokinase, and resveratrol.
Magnesium L-Threonate contains a form of magnesium bound to L-threonine acid. This specific structure allows magnesium to cross the blood-brain barrier more effectively than many other magnesium forms. It might help support cognitive health, mental clarity, and nervous system function.
Magnesium could support brain signaling by regulating synaptic activity between neurons. It may help control the flow of calcium into nerve cells, which is important for maintaining balanced neurotransmission. L-threonate may improve sleep quality and daytime functioning.
As per the official website, this formula might contribute to energy metabolism by assisting enzymes involved in ATP production, helping nerve cells maintain consistent energy for signaling and repair.
NMN Supplement combines Nicotinamide Mononucleotide, commonly known as NMN, which is a naturally occurring compound involved in the body’s NAD+ production pathway. NMN serves as a direct precursor to nicotinamide adenine dinucleotide.
Inside the cell, NMN is converted into NAD+, which is critical for in cellular energy metabolism. NAD+ is required for redox reactions that allow mitochondria to convert nutrients into ATP. NAD+ also supports enzymes known as sirtuins and PARPs, which are involved in cellular repair and stress response pathways. These enzymes help maintain DNA stability and regulate how cells adapt to metabolic and environmental stress.
As per the official website, this formula supports better metabolic health by influencing how cells process glucose and fatty acids. NAD+ dependent enzymes help regulate insulin signaling, lipid metabolism, and energy balance. Through these pathways, NMN supports metabolic processes that contribute to stable energy utilization and weight regulation at the cellular level.
Tongkat Ali Complex may support physical performance, energy balance, and exercise capacity. It may interact with hormonal signaling, energy metabolism, and stress response pathways involved in physical output and recovery.
The formula contains tongkat ali root extract 200:1, which is a highly concentrated form of Eurycoma longifolia. The root contains quassinoids and eurypeptides, which might support testosterone regulation and cortisol balance.
Tongkat Ali may also support energy and vitality by influencing the hypothalamic pituitary adrenal axis. This system helps regulate how the body responds to physical and mental stress.
As per the official website, the Tongkat Ali Complex also contains tribulus terrestris fruit extract, which provides steroidal saponins, including protodioscin, that may support androgen-related pathways. While tribulus does not directly increase hormone production, it may help support hormone receptor activity and nitric oxide signaling. Improved nitric oxide availability supports blood flow, oxygen delivery, and nutrient transport to working muscles during exercise.
Fadogia agrestis formula uses a concentrated stem extract, such as a 10:1 ratio, which provides a higher amount of plant compounds compared to raw plant material. It may support physical performance and energy balance.
The stem of Fadogia agrestis contains alkaloids, saponins, and flavonoids, which might support endocrine signaling pathways related to physical output and muscle function. These pathways influence how the body regulates anabolic and catabolic processes that affect muscle maintenance.
Fadogia agrestis could also support hormones, particularly luteinizing hormone signaling, which animal studies say might help regulate testosterone production. This could help with muscle protein synthesis, strength development, and recovery after resistance training. Supporting this signaling pathway may help maintain muscle mass when combined with consistent training and adequate nutrition.
Citrus bergamot extract formula provides a full-spectrum extract that contains multiple bioactive compounds found in the bergamot fruit, which may support cardiovascular and metabolic function. The extract includes flavonoids such as neoeriocitrin, naringin, and neohesperidin. These compounds participate in antioxidant activity by helping neutralize reactive oxygen species produced during normal metabolism.
Melitidin and bruteridin in bergamot may influence enzymes such as HMG-CoA reductase, which supports your body’s internal cholesterol production pathway. Citrus bergamot extract could also support glucose and fat metabolism by influencing mitochondrial efficiency and insulin signaling pathways. These processes may promote lipid regulation, antioxidant activity, and cellular energy balance.
As per the official website, the Lion’s Mane mushroom formula may promote neurological and immune support. Lion’s Mane contains hericenones and erinacines, which could support nerve growth factor and brain-derived neurotrophic factor activity. Lion’s Mane may help support the neurogenesis process by influencing pathways related to neuronal growth and repair, potentially supporting long-term cognitive function.
The makers state that the formula might support the immune system through its beta-glucans and polysaccharides. These compounds function by interacting with macrophages and natural killer cells by binding to pattern recognition receptors. This interaction helps regulate immune response activity and supports normal immune signaling without overstimulation.
Quercetin formula may support metabolic balance, cardiovascular function, and immune system activity. It could influence AMP-activated protein kinase, or AMPK. AMPK acts as an energy sensor within cells, helping regulate how the body uses glucose and fatty acids when energy demand changes. When AMPK activity is supported, cells tend to favor improved lipid metabolism and more efficient energy use, which helps maintain healthy cholesterol patterns already within the normal range.
Quercetin also functions as an antioxidant by scavenging reactive oxygen species produced during normal metabolism. It might help maintain healthier cellular environments throughout the cardiovascular and immune systems. The makers also added bromelain in this formula, which may help break down proteins in the digestive tract that can enhance quercetin uptake into circulation.
Double Wood Supplements was founded in the year 2013 by twin brothers Reese Wood and Evan Wood. The company states that it is privately held and operates independently, with no ownership or control from large corporations or conglomerates. This structure allows strategic and quality-related decisions to remain internal.
According to the brand, its founders continue to play an active role in guiding the business. Double Wood presents this founder-led model as a way to maintain closer oversight and enable faster decision-making. The company also states that it does not face pressure from outside investors to shift its direction or compromise its standards.
The brand reports more than a decade of continuous operation. During this time, it claims to have expanded its product catalog while maintaining stable business practices. This longevity may indicate consistency in management and an ability to grow without frequent changes to its core identity.
Double Wood further states that it follows the same principles across its operations. These include transparent labeling practices and public access to third-party laboratory testing. The brand positions these measures as ongoing standards rather than isolated or promotional efforts.
Double Wood Supplements does not publicly report funding or running brand-specific clinical trials on its finished products. The brand relies on third-party laboratory testing to confirm purity and label accuracy, but this testing does not measure real-world effectiveness or outcomes in people. As a result, product performance is inferred rather than directly demonstrated.
The brand’s evidence base depends mainly on existing scientific literature rather than studies designed around Double Wood’s exact formulations. Many source studies differ in study length, participant size, and use conditions. These differences limit how closely the findings apply to everyday consumer use. Without product-specific trials, there is limited data on long-term use, consistency of results, or how products perform across different users.
Now Foods and Double Wood Supplements differ primarily in scale, product scope, and their respective approaches to supplementation. The brand Now Foods operates as a large, family-owned natural products company with a long-standing presence in the industry. Its portfolio includes more than 1,400+ products, extending beyond traditional products to encompass essential oils, natural foods, beauty and personal care, sports nutrition, and pet health. Meanwhile, Double Wood Supplements functions on a much smaller scale and focuses almost entirely on products that include targeted formulas rather than broad lifestyle wellness.
The difference in product breadth is significant. Now Foods offers a wide selection of vitamins, minerals, herbs, and botanicals designed for everyday use. Examples include products such as Kelp 150 mcg tablets, Garlic Oil softgels, Rei-Shi Mushroom capsules, Turmeric Extract liquid, Astragalus capsules, and Tart Cherry formulas. These sit alongside probiotics, fiber products, omega fatty acids, and antioxidant formulas, allowing multiple health needs to be addressed within one brand. On the other hand, Double Wood Supplements maintains a narrower catalog built around specific compounds, with products such as Magnesium L-Threonate (Magtein), NMN capsules and powder, Berberine, Lion’s Mane Mushroom, Tongkat Ali Extract, Alpha GPC, and Phosphatidylserine. The lineup reflects a focus on individual ingredients rather than broad-category formulations.
The brands also differ in how they define health support. Now Foods organizes its products around general fitness areas such as immune support, digestive health, bone and joint support, cognitive health, heart health, and children’s health. This structure aligns with routine, long-term supplementation. Double Wood Supplements groups products around more targeted support, including brain health, healthy aging, metabolism, sleep, stress management, and men’s health. Many of its products are commonly combined into stacks, such as NMN with Resveratrol or multiple magnesium forms for specific use goals.
Ingredient philosophy further distinguishes the two. Now Foods places strong emphasis on traditional herbs and botanicals, often offering whole-herb or classic extract formats such as passion flower, saw palmetto, feverfew, hawthorn extract, and echinacea. Its catalog reflects long-established herbal use alongside basic nutrients. Double Wood Supplements leans more toward isolated nutrients and standardized extracts, offering defined compounds such as Nattokinase, CDP Choline, Magnesium Taurate, Vitamin D3 plus K2 liquid drops, and other single-ingredient formulations.
Now Foods highlights in-house manufacturing control and supports this with multiple third-party certifications, including USDA Organic, Non-GMO Project Verified, Certified Gluten Free, and Informed Sport for select products. The brand also references independent testing initiatives related to product quality in the broader market. In comparison, Double Wood Supplements emphasizes third-party laboratory testing at the product level and provides Certificates of Analysis, allowing verification of individual product batches rather than relying primarily on category-wide certifications.
Now Foods operates as a broad-spectrum brand offering extensive category coverage, traditional herbal options, and large-scale manufacturing supported by recognized certifications. Meanwhile, Double Wood Supplements operates as a focused brand centered on specific compounds, targeted use cases, and product-level testing transparency.
Bulk Supplements and Double Wood Supplements both operate in the single-ingredient product space, but they are designed for fundamentally different use cases and consumer preferences. The brand Bulk Supplements specializes in pure nutritional ingredients offered primarily in powder form and in a wide range of quantities, from small personal-use bags to multi-kilogram bulk options. Its model prioritizes cost efficiency, flexibility, and customization, making it well-suited for individuals and manufacturers who want direct control over dosing, blending, and formulation without added excipients or delivery formats. Double Wood Supplements, by contrast, focuses on transparency, science-backed quality, and accessibility through targeted, single-ingredient capsules and tablets.

Both brands address the demand for simple formulation, but they diverge in execution. Bulk Supplements prioritizes scale and formulation freedom, while Double Wood prioritizes convenience, clarity, and purpose-driven design.
Bulk Supplements’ lineup includes Creatine Monohydrate Powder, L-Citrulline DL-Malate 2:1, Beta-Alanine Powder, NMN Powder, Whey Protein Isolate, Collagen Peptides Powder, and a wide selection of amino acids, vitamins, and minerals. Double Wood Supplements takes a more targeted approach, offering products formulated around specific fitness areas, including Magnesium L-Threonate (Magtein), NMN Capsules, Quercetin, Lion’s Mane Mushroom, and Citrus Bergamot Extract.
The overall product range also varies in scope. Bulk Supplements maintains an extensive catalog of more than 500 products covering muscle building, hydration, digestion, heart health, brain support, and protein support. Its organic selection includes options such as Organic Lion’s Mane Mushroom Powder and Organic Chlorella. On the other hand, Double Wood Supplements operates with a narrower catalog that concentrates on specific use cases such as cognitive support, stress management, sleep, metabolism, liver health, and healthy aging, with products like Fadogia Agrestis, Nattokinase, Resveratrol, Magnesium Taurate, and L-Theanine.
Format preference is another area of contrast. Bulk Supplements is predominantly powder-based, with capsules and softgels available for select products, including Creatine Capsules, Fish Oil Softgels, Vitamin D3 Softgels, and CoQ10 Softgels. This model is suited to people familiar with weighing or measuring products. Meanwhile, Double Wood Supplements places greater emphasis on capsule and liquid formats, aligning more closely with users seeking consistency and simplicity in daily intake.
Price positioning reflects these structural differences. Bulk Supplements generally operates in a lower price range, particularly for powders sold in larger quantities. Many core products, such as Creatine Monohydrate Powder, L-Glutamine Powder, and Vitamin C Powder, commonly fall within approximately the $12 to $25 range, depending on size, with a lower cost per serving as quantity increases. Double Wood Supplements is positioned at a higher average price point, with many capsule-based products, including Magnesium L-Threonate, Tongkat Ali, NMN Capsules, and Berberine, typically priced between roughly $20 and $50 per bottle. The difference largely reflects format, extract standardization, and convenience rather than ingredient overlap alone.
Both brands emphasize quality assurance, though their communication differs. Bulk Supplements highlights manufacturing in cGMP-compliant, FDA-registered facilities and states that products are third-party tested, with certificates of analysis available upon request. Double Wood Supplements also provides third-party testing and access to COAs, while placing stronger emphasis on research-driven ingredient selection and product validation.
Bulk Supplements focuses on ingredient-level flexibility, bulk purchasing, and lower cost per serving. In comparison, Double Wood Supplements is structured around predefined formulations intended to address specific goals, prioritizing ease of use and standardized dosing over customization.
