Precision Fuel & Hydration PH 1500 50
750 mg of sodium per tablet is the strongest tablet in Precision's own PH range, 50% more than their PH 1000 and three times PH 500 (250 mg), dissolved in the same 16 fl oz of water as every other PH tablet so the concentration goes up without changing the routine.
Score breakdown
Each dimension below is scored 0 to 100 against a fixed scale, not against the rest of the catalog, so adding a product never moves this number. The overall score is the average of the dimensions this product declares data for. How the scales are set →

Verdict
what it does · what it costsWhat it does well
- 750 mg sodium, 125 mg potassium, 24 mg calcium, and 12 mg magnesium per tablet, more than double PH 500 across every mineral
- One tablet covers what would take roughly 2.3 GU Hydration Tabs (320 mg sodium each) to match
- Same roughly $1.20/tablet price as a single PH 500 or PH 1000 tablet despite carrying up to 3x the sodium of PH 500
What it costs you
- At 750 mg sodium per 16 fl oz, this is a heavy-sweat, hot-weather tool, not an everyday tablet; two or three in a day approaches the FDA's 2,300 mg/day sodium guidance from this product alone
- 12 kcal and 4 g of carbs per tablet is still negligible fuel next to a 19 g-carb drink mix like Skratch's Sport Hydration Drink Mix
- Sold in a smaller 10-tablet tube versus PH 500's 15-tablet tube, so it runs out faster per tube

Who this is for
the numbers, appliedThe field tells you what it is. This is who should act on it.
Worth the money if
- You're a heavy or salty sweater who needs a high sodium dose without carrying extra tablets
- You already use Precision's PH system and want the top-strength option for hot races or long efforts
Look elsewhere if
- You sweat lightly or are new to sodium supplementation; start with PH 500 or PH 1000 instead
- You want carbohydrate alongside electrolytes; pair this with a fueling product rather than relying on it alone
