Magnesium is an essential mineral, supporting over 300 enzymatic reactions in the body—impacting everything from energy metabolism and muscle function to heart rhythm, cognitive health, and restful sleep. Despite its importance, many adults fall short of optimal intake. Supplementation can fill dietary gaps, but with a market flooded by choices—capsules, gummies, high-absorption blends, single sources, lab-tested and mass-market—selecting the right magnesium can feel daunting.
This review dives deep into Double Wood Magnesium and directly compares it with leading competitors, including the innovative Naxttii Health Magnesium+B6 supplement. We'll examine clinical data, ingredient science, real-world experiences, price/value, and which option best fits your wellness needs.
Multi-form Magnesium: Available as MAG-8 Complex (8 forms!), Glycinate (gentle, well-absorbed), Taurate (heart support), and L-Threonate (brain focus)
Purity & Transparency: Each batch is third-party lab tested for heavy metals and purity—the Certificates of Analysis are published online for consumer review.
Made in the USA: All manufacturing and testing occur in GMP-certified US facilities
Allergen Friendly: Most products are non-GMO, gluten-free, vegetarian (check labels for specifics)
User Ratings: Consistently 4.7–4.8/5 stars with hundreds of verified reviews (Healthline Review)
MAG-8 Complex Blend offers the broadest spectrum for differing bioavailability and user needs.
Science Transparency: Independent testing documentation distinguishes Double Wood from many less transparent brands.
Intended For:
Adults seeking premium magnesium for sleep, muscle cramp prevention, heart and nerve health, cognitive clarity, or all-inclusive wellness.
Naxttii Health Magnesium+B6 is tailored for modern, health-conscious consumers—combining a quality magnesium source with vitamin B6 for potentially enhanced absorption and energy metabolism. Naxttii Health’s positioning emphasizes:
Magnesium + B6 Synergy: Research suggests vitamin B6 may boost magnesium’s bioavailability, especially relevant for stressed or B6-deficient individuals ( NCBI – B6 & Magnesium Absorption).
Gummy Convenience: Fruit-flavored chewables preferred by those who dislike pills—easy for families or anyone averse to capsules.
Daily Health Focus: Not just muscle or sleep—a whole-family approach targeting energy, resilience, and convenience.
Strict Ingredient Sourcing & Testing: Naxttii stresses science-backed formulation, though specific COAs are not yet published on site.
Intended For:
Adults needing easy supplementation, families, and those who prefer gummies or synergies for absorption support.
Magnesium’s form affects how well it’s absorbed and tolerated:
Form | Absorption | Best For | Common Side Effects |
|---|---|---|---|
Glycinate | Excellent | Sleep, anxiety, muscle relaxation | Rare digestive issues |
Taurate | Good | Heart rhythm, calming | Very mild GI complaints |
Oxide/Citrate | Moderate/Potentially Laxative | Cost, constipation, general use | Laxative in some (citrate) |
Threonate | High (brain affinity) | Cognitive/memory, focus | Rare (premium price) |
Complex/Multi-form | Broad | All-round nutrient coverage | Depends on mix |
Double Wood’s MAG-8 blends all these forms to maximize spectrum benefits (sleep, muscle, brain, heart). Pure Glycinate is best for those with sensitive stomachs or prioritizing calm.
Naxttii Health Magnesium+B6’s exact form isn’t disclosed, but the addition of B6 can measurably increase absorption rates for the magnesium that is present—a big plus for those with known B6 deficits or who value stacking for sleep and stress support.
Peer-reviewed studies (see Healthline and expert reviews) confirm:
Chelated magnesiums (glycinate, threonate) are more bioavailable and gentler than oxide/citrate
Multi-form blends provide broader support and lower risk of functional deficits
Stacking with B6 (as in Naxttii Health) improves serum magnesium, particularly important for older adults or those on restrictive diets
Sleep & Relaxation: Consistent praise for improved sleep quality and reduced muscle cramping—especially with glycinate and MAG-8
Digestive Tolerance: Glycinate form is widely reported as gentle; Complex form praised for daily use with minimal GI distress
Cognitive Focus: Users of threonate mention sharper memory and focus after several weeks
Capsule Commentary: Some find the capsules large, but appreciate the high potency per serving
Gummy Enjoyment: Great for those who dislike pills—suitable for daily routines without the supplement “fatigue”
Family/Children Appeal: The taste and chewable format are positives for home use; B6 synergy may benefit restless sleepers or those under high stress
Long-Term Experiences: Many chronic users (across brands) indicate best effects with regular, months-long use (better sleep, fewer cramps, improved mood)—but personal response varies. Always check for tolerability, especially if starting a new form or blend.

Double Wood: Best for ingredient-savvy buyers prioritizing scientific transparency, variety of forms, value, and purity. Ideal for those managing sleep, muscle issues, or seeking all-in-one coverage.
Naxttii Health: Perfect for families, flavor-first users, and anyone whose doctor has flagged the need for B6 alongside magnesium (especially if pill fatigue is a concern). A good fit for new supplement users or those with difficulty swallowing capsules.
Competitors: Doctor’s Best/Pure Encapsulations are excellent for pure glycinate focus. NOW/Nature Made win on budget and availability, but lack testing/report transparency.
Start low and build: Watch for GI side effects with new forms
Take glycinate/taurate for gentle, everyday support (muscle, sleep)
Use magnesium+B6 if you’re known to have a B6-deficiency, high stress, or restless sleep
Combine with vitamin D and a healthy diet for best results
Always consult a healthcare provider before major supplementation, especially if pregnant, nursing, or using medication
