9 signs of magnesium deficiency Indians commonly miss
Indian diets look full of vegetables but have quietly become magnesium-poor — refined grains have replaced millets, and decades of intensive farming have stripped magnesium from the soil. The result: half the country is running low and calling it "stress". Here are nine everyday signs that point at magnesium.

Why deficiency flies under the radar in India
- Serum tests miss it. Only 1% of body magnesium is in blood — a normal serum result can still mean depleted tissues.
- Diet has thinned out. Polished rice, maida and low-mineral produce dropped average magnesium intake ~30% in two generations.
- Everyday habits burn it fast. Chronic stress, tea/coffee, antacids (PPIs) and diuretics all drain magnesium.
- Symptoms look like everything else. Fatigue, cramps, poor sleep and anxiety are usually blamed on work — and never linked to a mineral.
The 9 signs — most people have 2–3 at once
1. Trouble falling or staying asleep
Magnesium is a cofactor for GABA — the calming neurotransmitter. Low magnesium = a nervous system that won't downshift at night.
2. Night-time leg cramps or restless legs
Classic magnesium sign. Muscles need magnesium to relax after contraction; without it they stay tense and cramp.
3. Migraine or tension headaches
Multiple RCTs show 300–600 mg/day of magnesium reduces migraine frequency. Elemental magnesium is included in Indian neurology migraine protocols.
4. Palpitations or a fluttery heartbeat
Magnesium stabilises the cardiac action potential. Low magnesium shows up as skipped beats and PVCs on Holter monitoring — often mistaken for anxiety.
5. PMS, cramps and mood dips before periods
Progesterone tanks magnesium in the luteal phase. Supplementing 200–400 mg/day is one of the best-studied non-hormonal PMS interventions.
6. Persistent low energy despite normal sleep
Every ATP molecule needs magnesium to become the usable form Mg-ATP. Low magnesium = your mitochondria are running on the wrong currency.
7. Anxiety, irritability and a short fuse
The stress response burns through magnesium fast. It's a two-way street: low magnesium raises cortisol, and high cortisol strips more magnesium.
8. Constipation
Magnesium pulls water into the bowel and relaxes intestinal smooth muscle. Chronic low magnesium is a common invisible cause of stubborn constipation.
9. Twitchy eyelids or facial tics
One of the earliest tells. If a lower eyelid has been fluttering for weeks, magnesium is the first thing to try.
The food-first fix (and why it usually isn't enough)
Best food sources for Indians: ragi, bajra, jowar, kaddu ke beej (pumpkin seeds), palak, methi, kaju, almonds and dark chocolate ≥70%. Rotate them in, but be honest — hitting 350 mg from food alone means eating like a nutritionist every day. A 200–300 mg supplement covers the shortfall.
Mag Absorb Pro — the four forms that actually get absorbed
A blend of Aquamin® marine magnesium, bisglycinate, chloride and aspartate — one for sleep and calm, one for cramps, one for energy, one for bone. No oxide filler. Third-party tested. Made in a USFDA / GMP / FSSAI facility.
