The story

Genuinely clean

Third-party COA on the website sold me. Prenatal Foundation has become part of my morning stack — no chalky aftertaste and no bloat.

Noticeable within a week

I train five days a week and recovery has been sharper. Ingredient list reads like a dietitian wrote it, which is basically the case.

Great, wish tub was bigger

Flavor is subtle in the best way. I'd love a family-size option of Prenatal Foundation.

Best in class

Tried AG1 and Ritual before this. Rivergrove wins on transparency and taste. Subscribe-and-save makes it a no-brainer.

My dietitian recommended it

She specifically flagged the sourcing standards. I've been on it three months and my labs improved at my last check-in.

Solid daily

Mixes clean in water, no gritty settle. Packaging is a little bulky but I'll take it for the quality.

Finally a brand I trust

I'm picky about what goes in my body during pregnancy planning. Rivergrove passed my OB's review.

Worth the price

You get what you pay for. Prenatal Foundation is not the cheapest option but the quality is obvious after two weeks.
