Highly bioavailable chelated magnesium bound to glycine. Supports sleep quality, bone mineral density, muscle function, and stress resilience - with minimal gastrointestinal side effects compared to other magnesium forms.
Curcumin is the primary bioactive polyphenol extracted from turmeric root. It modulates multiple inflammatory pathways simultaneously - including NF-κB, COX-2, and key cytokines - but its clinical impact depends entirely on the formulation. Standard curcumin without a bioavailability enhancer is poorly absorbed; piperine, phospholipid complexes, and nanoparticle delivery systems can increase absorption by up to 2,000%.

| Evidence grade | Strong | Moderate |
| Primary health goal | Bone & Muscle | Inflammation & Recovery |
| Research focus | Sleep quality and relaxation; Bone mineral density support; Muscle function and recovery | Joint comfort and osteoarthritis support; Exercise recovery and DOMS reduction; Systemic inflammation and oxidative stress |
| Studied dose and form | Magnesium Glycinate capsules ... 200–400 mg elemental Mg ... 1–2 hours before bed | Curcumin + piperine (BioPerine®) ... 500–1,500 mg curcuminoids + 5–20 mg piperine ... With a fat-containing meal; split into 2 doses if >1,000 mg |
| What to check on the label | Look for products that list 'magnesium glycinate' or 'magnesium bisglycinate' as the active ingredient - both names refer to the same chelated compound. Avoid blended 'magnesium complex' products that combine a small amount of glycinate with inexpensive magnesium oxide; the label… | Formulation is everything with curcumin - this is not a supplement where higher milligrams on the label equals better outcomes. A product with 1,500 mg of unformulated 95% curcuminoid extract and no bioavailability enhancer will produce lower serum concentrations than 500 mg of a… |
| Main safety note | Magnesium glycinate is well tolerated at standard doses. Loose stools or GI discomfort may occur at doses above 400 mg - reduce dose or split if this occurs. Individuals with chronic kidney disease or renal impairment should consult a physician before supplementing, as impaired k… | Curcumin is well tolerated at standard doses; GI upset (nausea, loose stools) is the most common side effect and usually resolves with dose reduction or taking it with food. Curcumin inhibits platelet aggregation and potentiates anticoagulant and antiplatelet medications (warfari… |
