Why It Works

Key Benefits

😴
Sleep Quality Improvement
Magnesium activates GABA receptors — the primary inhibitory neurotransmitter system responsible for relaxation and sleep onset. Deficiency is directly linked to insomnia and restless sleep. Glycinate is the preferred form for sleep because it avoids the GI side effects of other forms at effective doses.
🧘
Stress & Anxiety Relief
Magnesium modulates the HPA axis (stress response system) and is a cofactor for over 300 enzymatic reactions. Chronic stress depletes magnesium; deficiency amplifies the stress response — creating a cycle that magnesium supplementation directly addresses.
💪
Muscle Relaxation & Cramp Prevention
Magnesium is the physiological calcium antagonist in muscle cells. Adequate magnesium allows muscles to fully relax after contraction — preventing cramps, spasms, and the restless legs that disrupt sleep.
❤️
Cardiovascular Support
Magnesium supports healthy blood pressure, arterial flexibility, and heart rhythm regulation. Meta-analyses show significant blood pressure reductions with magnesium supplementation in deficient individuals.
🦴
Bone Density Support
60% of the body's magnesium is stored in bone. Adequate magnesium is required for proper calcium and Vitamin D metabolism — making it an essential component of any bone health protocol.
This product is for you if…
You experience difficulty falling or staying asleep
You have muscle cramps, restless legs, or nighttime muscle twitching
You experience stress-related tension, anxiety, or irritability
You follow a calorie-restricted or plant-based diet (magnesium deficiency is common)
You take a GLP-1 medication and need magnesium support during reduced dietary intake
You experience constipation — magnesium glycinate has gentle stool-softening effects at higher doses
⚠️Consult your healthcare provider if…
You have kidney disease — magnesium is renally cleared; consult your physician before supplementing
You take certain antibiotics (quinolones, tetracyclines) — magnesium may reduce absorption; separate by 2 hours
You take bisphosphonates for osteoporosis — separate dosing by 2 hours
You take diuretics — some diuretics affect magnesium balance; consult your physician

Science

Clinical Evidence

Every Kasivit product is backed by peer-reviewed research. Here's what the science says.

🔬
Magnesium supplementation significantly improved sleep quality, sleep onset latency, and insomnia severity in elderly adults with insomnia in a double-blind RCT
🔬
Magnesium supplementation significantly reduced systolic blood pressure by 2-3 mmHg in a meta-analysis of 34 RCTs — with greater effects in those with hypertension or magnesium deficiency
🔬
45% of Americans do not meet the estimated average requirement for magnesium from dietary sources alone — making it one of the most common micronutrient insufficiencies in the US

Key Features:

  • 275 mg Elemental Magnesium Per Serving — from 2,500 mg Magnesium Glycinate
  • Supports Healthy Sleep, Muscle Relaxation, and Stress Recovery
  • Glycinate Form: Superior Absorption, Gentle on the Stomach
  • Physician-Recommended for GLP-1 Users and Active Weight Management

Magnesium is one of the most critical minerals in the human body — involved in over 300 enzymatic reactions — yet it is chronically under-consumed. Studies show that nearly half of Americans fail to meet their daily magnesium requirement from diet alone. This gap widens further for individuals on GLP-1 receptor agonists, who eat significantly less food and are at heightened risk of micronutrient depletion.

Kasivit Magnesium Glycinate delivers 275 mg of elemental magnesium per serving (three capsules) sourced from 2,500 mg of magnesium glycinate — a chelated form with documented superior bioavailability compared to magnesium oxide.
