2. Consider Supplementation—But Choose Wisely
The Recommended Dietary Allowance (RDA) for adults over 50:
Men: 420 mg/day
Women: 320 mg/day
Best forms for seniors:
Magnesium glycinate: Gentle on the stomach, excellent for sleep and anxiety.
Magnesium citrate: Good for constipation (but can cause loose stools).
Magnesium malate: Supports energy and muscle function.
Avoid: Magnesium oxide—it’s poorly absorbed and mostly acts as a laxative.
Caution:
Kidney disease? Consult a doctor before supplementing—excess magnesium can build up.
On medications? Magnesium can interact with antibiotics, osteoporosis drugs (bisphosphonates), and muscle relaxants. Take supplements 2–4 hours apart from meds.
3. Topical Magnesium (For Cramps & Absorption)
Magnesium oil or lotion applied to legs or feet may help with muscle cramps and bypass digestive issues.
Evidence is anecdotal but widely reported by seniors.
The Bottom Line
Magnesium isn’t a miracle cure—but it’s a foundational nutrient that quietly supports nearly every system in the aging body. For seniors, optimizing magnesium intake can mean fewer cramps, deeper sleep, steadier heartbeats, and stronger bones.
Start with food, consider a high-quality supplement if needed, and talk to your doctor—especially if you take medications or have kidney concerns.
