Supplement rankings, when we can defend them

This is a reserved section, not an empty blog category. Brands can buy a review. A weaker score cannot buy a higher rank. Rephora Labs products, from the same company that publishes this site, may appear here and will be labeled.

Coverage on file, not a Best of slot

Rephora Labs is owned by OCN LLC, the same company that publishes this site. That is not independence. We still rate the stick as a heat, shift, and drive hydration habit with 5 g of creatine, not as a Best of rank. Mix in 16 oz. Informal tasting notes, the full review, and the electrolytes guide are the coverage, with the label attached.

Tasting notes · not a study

Stick packs we mixed, plus one gummy

Informal drinkability notes. Labels in a separate table. Not “most effective.” Not a Best of rank.

Electrolytes, sports-drink hype, creatine habit

Heat, shift, drive. Sodium when you sweat. Mix in 16 oz, not 12. One stick is adherence, not magic synergy.

Why wait?

A ranking without testing notes is a listicle. Nutritionist Guide will not publish a “best vitamin D” until we can say what we checked, what we did not check, and how a brand could lose the top slot next year. Read the guides in the meantime. They are the same standard, applied to food and physiology instead of bottles.
