BODYARMOR Flash I.V.

BODYARMOR Flash I.V. wins on potassium: 700 mg per stick packet — nearly double Re-Lyte's 400 mg and more than triple LMNT's 200 mg — making it ideal for athletes who prioritize muscle function and cramp prevention. The coconut-water base adds naturally occurring potassium, while 65 mg of magnesium and 11 mg of zinc (unique on this list) round out the mineral panel. Backed by Coca-Cola with widespread retail distribution, zero sugar, and professional athlete endorsements, it offers mainstream accessibility. Trade-offs exist: sodium at 510 mg trails both LMNT and Re-Lyte substantially, making it less suitable for high-sweat situations. At $1.25 per serving, it's among the priciest options here, with only six flavors. The 15 kcal from coconut water matter for strict zero-calorie seekers. For activities like cycling, tennis, or soccer where cramping is a risk, or for potassium-light diets, Flash I.V. is the most targeted formula here.
