"A child's gut microbiome is almost entirely established by age three. Feeding it the right prebiotics early sets the foundation for lifelong digestive health."

"HMOs are one of the most exciting advances in pediatric nutrition — clinically shown to support the beneficial bacteria that keep digestion regular."

"I see so many families stuck on laxatives. A prebiotic approach that works with the body — not against it — is exactly what most of these kids need."

How is this different from a laxative?
Stimulant laxatives irritate the bowel lining to force a contraction, which your kiddo's gut can start relying on just to move. Magnesium citrate works differently: it draws water into the intestines through simple osmosis, the same process your body already uses for hydration and stool softness.
Does magnesium need time to "build up," like other supplements?
No. Unlike prebiotics or probiotics, which take weeks to shift the gut microbiome, magnesium is water-soluble and used up daily, so it isn't stored like some vitamins.
Will my picky eater actually drink it?
Most do! It's naturally flavored pink lemonade with real fruit (kiwi and lemon), no added sugar, colors, or artificial ingredients, and mixes into water or a smoothie so kids get the taste without knowing it's "medicine."
Is it safe for daily, long-term use?
Yes. Growing Up® Magnesium is formulated for kids ages 1+ and safe for daily use: gluten-free, with no added sugar or artificial ingredients.
Why magnesium glycinate + citrate instead of other forms?
This blend pairs citrate's faster-acting osmotic support with glycinate's gentler, highly-absorbable profile, supporting hydration and digestion without the harshness of forms like magnesium oxide at high doses.

Our now 3.5 year old was struggling with constipation pretty much since starting solids. The same struggle it seems like most toddler parents are dealing with.
We started with growing up probiotics and that helped but we still were facing withholding and occasional constipation. As soon as this growing up magnesium came out, I ordered it and this has been the extra piece we needed. We have been using this plus the probiotic daily for our 3.5 year old and 2 year old pretty much since it hit the market. The only pause we had was when they had trouble keeping it in stock. And we noticed fewer bowel movements during that time.
I now find myself wishing I was as regular as my kids. They have healthy bowel movements 2-3 times daily. Is there an adult version coming soon?!

I know this product is marketed for kids, but I randomly ended up trying it myself and it’s honestly been one of my favorite finds. I’ve been taking it every night for over six months, and it’s become part of my bedtime routine.
It helps me sleep like a baby, and I’ve also noticed a big difference in my digestion and regularity. The flavor is great, and I really appreciate the clean ingredients.
I’m 39 years old, so definitely not the target audience, but I can genuinely say this works 10/10. don’t let the “for kids” label stop you from giving it a try 😅
