Products Offered By Double Wood Supplements

1. Magnesium L-Threonate (Magtein)

   Magnesium L-Threonate (Magtein) offers a highly bioavailable form of magnesium that may cross the blood-brain barrier to increase magnesium levels in the brain. It could support cognitive aspects, including memory and learning, neuroprotection, and stress reduction.

   According to its official site, a 4-capsule serving of the formulation provides 2000mg of magnesium L-threonate (Magtein). The makers also suggest pairing it with L-Theanine or Apigenin to help support more restful sleep and minimize nighttime awakenings.

2. NMN Supplement

   As per its official site, one serving (2 capsules) of Double Woods’ NMN features 250mg of NMN (nicotinamide mononucleotide). NMN could help restore the body’s diminished NAD+ levels, which may help support healthy aging and cellular function.

   NMN could help support DNA repair and activate SIRTUIN genes, which could help support longevity. Research suggests that NMN may support cognitive function by enhancing mitochondrial function. It may also help stimulate metabolism, which might help contribute to your fitness goals. The makers suggest taking two NMN capsules daily, ideally split into two 125 mg doses taken with food.

3. L-Citrulline

   Double Wood’s L-citrulline could help support physical performance and cardiovascular function. One serving (2 capsules) provides 1200mg of L-citrulline, with the whole bottle containing 210 capsules.

   Research indicates that L-citrulline may be more effective at boosting L-arginine levels in your body than direct L-arginine supplementation. The increase in L-arginine may support the synthesis of nitric oxide, a molecule that may help improve blood circulation.

   Increased blood flow may support better muscular endurance and boost energy levels by increasing oxygen delivery to muscle cells. These benefits contribute to better exercise performance and endurance.

4. Rhodiola Rosea Extract

   Rhodiola Rosea Extract by Double Wood may improve mental and physical stamina, making it particularly beneficial if you are facing prolonged stress or engaging in low-intensity exercise.

   Double Wood’s Rhodiola Rosea extract features a concentrated 3% salidrosides content, which could support a more positive mood and boost energy levels. The makers suggest consuming 1-2 Rhodiola Rosea extract capsules in the morning to experience its energizing effects.

   The makers state that Double Wood’s Rhodiola Rosea extract is made in the USA from globally sourced, non-GMO, vegan, and gluten-free ingredients. Such a composition may indicate adherence to various dietary restrictions.

5. TUDCA

   TUDCA (tauroursodeoxycholic acid) by Double Wood aims to support liver health and function. Tauroursodeoxycholic acid is known as a water-soluble bile acid that can maintain healthy liver enzyme levels. Such effects may help optimize bile flow from the liver to the intestines, which could support healthy digestion.

   Double Wood’s TUDCA could also help support gallbladder, intestinal, immune, and thyroid functions. As per its official site, a two-capsule serving of TUDCA features 500mg of tauroursodeoxycholic acid. TUDCA may also provide neuroprotective benefits by safeguarding brain cells from oxidative damage and supporting neural function.

6. Magnesium Glycinate

   Magnesium Glycinate by Double Wood pairs elemental magnesium with the amino acid glycine. Magnesium glycinate has calming effects, which promote relaxation and support more restful sleep. Double Wood’s Magnesium Glycinate may also help support muscle and nerve activity, blood sugar control, and bone density.

7. Berberine

   Double Wood’s Berberine provides 500mg of Berberine per capsule, with 60 capsules per bottle. Berberine is a plant-based alkaloid that may support healthy blood sugar levels, improve metabolism, and support heart health.

   Berberine also helps activate AMPK, which may improve cellular energy balance and support healthy aging. The process also encourages better fat-burning, reduces inflammation, and supports longevity.

8. NAD+

   Double Wood’s NAD+ formula contains 500mg of nicotinamide adenine dinucleotide (NAD) per 2-capsule serving. NAD is a molecule that supports cellular energy production and healthy aging, which may support your body’s ability to repair cells and maintain vitality.

   NAD+ intake could help raise NAD levels, which may translate to improved memory, focus, and cognitive processing. It might also help support your immune system, which could make it more resilient to infections and diseases.

9. L-Theanine

   Double Wood’s L-theanine is a non-GMO and gluten-free formulation that could support feelings of relaxation without making you feel overly drowsy. Consistent use of L-theanine may support cognitive functions positively by helping improve memory, focus, and cognitive processing.

   As per its official site, one capsule provides 200mg of L-theanine, with 120 capsules in one bottle. The makers state that Double Wood L-theanine is made and tested in the USA, with rigorous checks for microbes and heavy metals.

10. NMN Powder

    Double Wood’s NMN Powder provides one gram of nicotinamide mononucleotide (NMN) per one-gram serving. NMN is known as a direct precursor to NAD+, a molecule your body metabolizes for energy, cellular repair, and metabolic function.

    Consistent use of NMN Powder might help support better energy levels, brain function, and healthy DNA repair with age. Some studies suggest that NMN could support muscle strength, heart health, and cellular protection by boosting NAD+ levels.

11. Spermidine

    Spermidine by Double Wood aims to support healthy aging and cognitive function. It contains Spermidine trihydrochloride, which is a polyamine molecule that is essential for supporting cellular metabolism.

    Double Wood’s Spermidine may support cell membrane integrity, preserve telomere length to support longevity, and promote cognitive health. The makers suggest starting with 1-2 Spermidine capsules (5-10 mg), and you may gradually increase to 2-4 capsules if needed.

Double Wood Supplements Advantages

1. Transparent COA Access

   Double Wood goes beyond just making quality claims, as the brand openly shares Certificates of Analysis (COAs) for each product. These documents are easy to find on their official website and provide detailed lab test reports for purity, potency, and ingredient accuracy.

   Each COA offered by Double Wood is based on third-party testing, which means the results come from independent testing labs, not in-house reports. COAs also include important safety data, which includes analyzing for the presence of pesticides, heavy metals, or harmful microbes.

   Reviewing the COAs could help confirm the safety and effectiveness of each Double Wood formulation before committing to a purchase. It could help ensure the accuracy of the information and give you confidence that what’s listed on the label matches what’s inside the bottle.

2. Diverse Product Range

   Double Wood provides a wide variety of formulations that may cater to multiple wellness goals. Whether you are interested in boosting your focus, strengthening your immune system, improving sleep quality, or supporting vitality, Double Wood offers formulations that help fulfill such requirements.

   For example, Double Wood offers NMN and NAD+ to support cellular metabolism and healthy aging, while formulations like L-theanine and L-citrulline may improve blood circulation and support cardiovascular health.

   Double Wood also offers a “Build Your Stack” option that lets you create a custom bundle tailored to your specific fitness goals. For instance, you can select the Nootropic Stack, which provides Alpha GPC and Uridine to support cognition and focus.

Double Wood Supplements Limitations

1. Lacks USP/NSF certification

   Double Wood falls short when it comes to third-party certifications. Specifically, the offerings from Double Wood lack approval from third-party organizations like the US Pharmacopeia (USP) and NSF International. These certifications help confirm that what’s on the label is actually in the bottle, without harmful contaminants.

   Even though Double Wood does offer third-party testing and shares Certificates of Analysis (COAs), these steps don’t carry the same level of oversight or industry-wide trust as official USP or NSF certifications.

   In contrast, competitors like Thorne back their products (like Creatine and Amino Complex) with USP and NSF seals. The lack of NSF and USP certifications could make the offerings from Double appear less credible.

2. Limited Blend Options

   If you’re looking for comprehensive, multi-ingredient formulas, the Double Wood brand may not meet your expectations. The brand sticks entirely to single-ingredient products, which means you won’t find convenient, all-in-one formulations.

   You’ll likely need to create stacks by pairing multiple single-ingredient formulations from Double Wood, which may be both time-consuming and expensive. For example, instead of a single stress-relief blend formula, you’d have to purchase single-ingredient formulations like Double Wood’s L-Theanine and Ashwagandha separately.

Double Wood Supplements Alternative Brands

1. Thorne

   Thorne provides an extensive catalog of over 150 products that feature multivitamins, probiotics, and protein powders, which cover multiple health categories, such as cognitive function, immune health, metabolism, and physical performance. The brand also offers 11 at-home test kits, including tests for thyroid, biological age, gut health, etc.

   Meanwhile, Double Wood takes a more targeted approach by focusing on single-ingredient formulations, such as Berberine, NAD+, and L-Citrulline. The offerings from Double Wood aim to support specific functions, such as metabolic support, cellular health, or cardiovascular function. Unlike Thorne, Double Wood does not provide any at-home health testing kits.

   For mind and mood support, Thorne pairs neurotransmitter precursors and adaptogens into single products like Emotion Balance Support. The formulation contains 5-HTP, Rhodiola extract, and L-tyrosine to support mood and emotional resilience.

   On the other hand, Double Wood provides single-ingredient formulations like L-Theanine, Uridine Monophosphate, and Alpha GPC. These formulations are linked to specific neurochemical pathways, such as GABA modulation or acetylcholine synthesis.

   Thorne and Double Wood also differ in their return policies. Thorne offers a 60-day satisfaction guarantee, which is subject to a 25% restocking fee. In contrast, Double Wood provides a 30-day refund window on only the first purchases, which may reflect a more restrictive return policy.

2. Wholesome Story

   Double Woods and Wholesome Story are different brands, each with unique approaches to product offerings, target audiences, and brand philosophies.

   Wholesome Story primarily caters to women, offering formulations that may support hormone balance, fertility, pregnancy, postpartum health, and daily health.

   Meanwhile, Double Wood focuses on a broader demographic. The brand offers multiple formulations to support brain health, anti-aging, immunity, sleep, etc. The offerings from Double Wood focus on research-backed and single-ingredient compounds, such as NMN, magnesium, or Berberine, to support various fitness goals.

   In the category of cognitive health, Double Wood offers nootropics like Uridine Monophosphate, CDP Choline, and L-Theanine, which support cognitive processes like neurogenesis, acetylcholine synthesis, and GABA modulation. The nootropics help support memory, focus, and stress response.

   Meanwhile, Wholesome Story does not offer nootropics or neurotransmitter-targeting formulations. However, offerings like DIM Complex and Myo-Inositol may influence mood by indirectly supporting hormonal balance and insulin regulation.

   Wholesome Story and Double Wood follow different approaches to maintaining customer engagement and education. Wholesome Story engages customers through informative blog content covering nutrition, health, and wellness topics. It also provides an affiliate program and offers rewards for successful referrals.

   Similarly, Double Wood offers a dedicated blog covering various health aspects and information about the brand’s offerings. The brand also provides a loyalty program to reward repeat purchases and increase consumer engagement.

   On the Better Business Bureau (BBB), Double Wood Supplements holds an “A+” rating, indicating a strong track record in customer service and ethical business practices. However, the BBB has not yet officially accredited Double Wood and its active application to the BBB is pending.

While many Trustpilot users appreciated the effectiveness of Double Wood formulations, some concerns have been raised around shipping speed, customer service responsiveness, or consistency between batches.

   The Double Wood brand is not listed on Reviews.io, which can limit the availability of additional feedback on the platform.

   Double Wood maintains a generally positive reputation on review websites. However, the feedback from consumers highlights a few areas of improvement, particularly in aspects like service and logistics.

2. Consumer Reviews

   To assess how real users receive Double Wood Supplements, we analyzed customer feedback from both Amazon and Trustpilot, focusing on two of their offerings, Magnesium L-Threonate (Magtein) and Berberine.

   Many consumers on Amazon praised Magnesium L-Threonate for providing cognitive and neurological support. Consumers noted improvements in memory, focus, and mental clarity, attributing these benefits to the formulation’s ability to cross the blood-brain barrier. Some users also experienced improved sleep quality and reduced muscle cramps after using Magnesium L-Threonate. However, a few consumers did not experience any benefits despite regular use.

   Double Wood’s Berberine also received praise from users focused on appetite control and fitness goals. Many reviewers experienced appetite suppression and reduced cravings within a few weeks of using Berberine. However, some consumers faced side effects like headaches or mild digestive discomfort after taking Double Wood’s Berberine formula.

   Broader feedback on Trustpilot reveals a more mixed picture. Many users on Trustpilot commend the Double Wood Supplements’ effectiveness and the occasionally responsive customer service of the brand. However, many reviewers reported issues with subscription charges, order fulfillment, and return policies. Complaints include unfulfilled promotions, poor communication, and skepticism about dosage accuracy.
