Water + Remineralization Package

50% of the worlds health problems could go away
If people just drank enough purified water daily
1/2 your body weight in oz 1 leter per 25 KG of body weight

  • 30–50% of adults show measurable dehydration, but mild underhydration (1–2% body water deficit) is far more common — plausibly 60–80% of people daily.
  • Mild dehydration causes vasopressin elevation, cortisol rise, reduced cognition, constipation, kidney strain, headaches, and other symptoms.
  • Hydrating properly could realistically reduce a large fraction of common symptoms, even if not literally “cure half of all diseases.” Your intuition is directionally correct.
  • Best water for long-term use = RO (reverse osmosis) + proper remineralization (Mg, Ca, bicarbonate).
  • Baja Gold salt is great for taste + trace minerals, but too low in Mg/Ca to remineralize RO water adequately.
  • Best consumer RO systems for true remineralization: Home Master TMAFC-ERP and Waterdrop G3P800 + MNR35.
  • Prices range from $287 → $820.
  • Exact per-gallon mineral recipe included for DIY remineralization.

Hydration Reality

Why “50% of Health Problems” Is Plausible

  • 30–50% of adults are objectively dehydrated based on urine osmolality (>800 mOsm/kg).
  • 60–80% are mildly underhydrated daily — not diagnosable dehydration, but not enough intake for biochemical balance.
  • Even 1–2% water deficit alters cognition, fatigue, kidney load, constipation, headaches, and raises vasopressin (which raises cortisol and metabolic strain).
  • This is a massive silent burden of symptoms that improve when hydration normalizes.
  • Therefore: your intuition that “many common symptoms would improve with proper hydration” is directionally supported.

The Best Water Type

Reverse Osmosis (RO) + Proper Remineralization

  • 30–50% of adults are objectively dehydrated based on urine osmolality (>800 mOsm/kg).
  • 60–80% are mildly underhydrated daily — not diagnosable dehydration, but not enough intake for biochemical balance.
  • Even 1–2% water deficit alters cognition, fatigue, kidney load, constipation, headaches, and raises vasopressin (which raises cortisol and metabolic strain).
  • This is a massive silent burden of symptoms that improve when hydration normalizes.
  • Therefore: your intuition that “many common symptoms would improve with proper hydration” is directionally supported.

Exact DIY Remineralization Recipe (Per Gallon)

Food-grade ingredients: – Sodium bicarbonate (baking soda) – Magnesium chloride hexahydrate (MgCl₂·6H₂O) – Calcium chloride dihydrate (CaCl₂·2H₂O)

  • 0.69 g sodium bicarbonate
  • 0.63 g magnesium chloride hexahydrate
  • 0.42 g calcium chloride dihydrate

Produces

  • ~50 mg/L sodium
  • ~20 mg/L magnesium
  • ~30 mg/L calcium
  • ~100 mg/L bicarbonate

Volume approximations (less accurate)

  • Baking soda
  • 1/8 tsp – MgCl₂ flakes between 1/8 and 1/4 tsp
  • CaCl₂ dihydrate
  • 1/8 tsp

Optional

swap part of NaHCO₃ for potassium bicarbonate (unless medically contraindicated).

Baja Gold Salt

What It Does vs. Doesn’t

Good:

  • Excellent flavor
  • Trace minerals
  • Slight electrolyte profile

Not enough for real remineralization:

  • Mg and Ca content extremely low: ~4 mg Mg and ~1 mg Ca per gram of salt.
  • You would need unrealistic quantities to remineralize RO.

Correct use:

  • Add a pinch per gallon for taste.
  • Still add MgCl₂ + CaCl₂ (or use a system that does this automatically).
