    I’ve tried several kids’ supplements, but this one actually made a difference! My 8-year-old seems more focused during homework time, and mornings have been smoother too. Plus, he loves the taste!

    I’ve been searching for a clean calcium supplement that’s truly plant-based and this one ticks all the boxes. No chalky aftertaste, and I love that it's sourced sustainably from Icelandic red algae.

    My 6-year-old actually asks for these every morning! The berry flavor is yummy and I love knowing she’s getting Vitamin C, D3, and elderberry in one gummy. No complaints about taste, no mess, and no fighting over vitamins—total mom win
