You're getting 420mg of **Magnesium** per tablespoon — right at the top of the clinical supplemental range (100–400mg) used in research on muscle function, energy production, and sleep quality. The liquid format means faster absorption than tablets or capsules, and the citrate form absorbs well, making this a solid option if you're looking to correct low magnesium levels or support relaxation.
Magnesium deficiency is extremely common — estimated to affect over half the population — and your body uses it in hundreds of processes, from keeping your heart rhythm steady to supporting bone density and nervous system function. At this dose, you're fully covered for general supplementation across those areas.
One thing to note: 420mg exceeds the tolerable upper limit of 350mg for supplemental magnesium, and citrate has a mild laxative effect at higher doses. If you experience GI discomfort, splitting the serving into two half-tablespoons throughout the day is worth trying.

CarrageenanThickener
Can break down into poligeenan (a known inflammatory) under stomach acid conditions. Tobacman (2001, Environmental Health Perspectives) reviewed evidence linking carrageenan to intestinal inflammation and ulceration. Major food brands (Silk, Stonyfield) have voluntarily removed it. Used only as a thickener — provides no health benefit.
FructoseSweetener
Added free fructose is metabolized in the liver and at habitual intake is linked to elevated triglycerides, hepatic fat accumulation, and insulin resistance; an avoidable sugar load with no supplement benefit.
Natural FlavorsFlavor
Broad regulatory category of flavor constituents derived from natural sources. Composition is proprietary and not disclosed — 'Natural Flavors' can include several hundred different compounds depending on the target flavor profile, including hexane-extracted constituents and proprietary carrier solvents. 'Natural' is a regulatory definition (21 CFR §101.22), not a safety guarantee.
