Getting Started with Growing Up ® Magnesium

Welcome!

This guide introduces you to Begin Health's Growing Up® Magnesium.

We developed this daily magnesium mix to support your growing kid's health, starting with hydration and digestion.

Picky eating, processed foods, and even soil depletion in modern produce can all leave gaps in a kid's mineral intake, specifically magnesium and potassium.

Growing Up® Magnesium helps support kids ages 1+ with a gentle blend of electrolytes and fiber, helping provide essential minerals while supporting hydration and gentle digestion.

What Growing Up® Magnesium Does

Growing Up® Magnesium is a magnesium and fiber blend designed to support growing kids while supporting hydration and gentle digestion.

It features:

• Magnesium (Glycinate & Citrate Blend) – a gentle, highly absorbable dual-form magnesium that supports mineral intake and light digestion.
• Potassium – an essential electrolyte that helps maintain hydration and fluid balance.
• Actazin® Green Kiwifruit Powder – a natural, whole-fruit source of prebiotics that supports gut health and healthy digestion.
• Agave Inulin – a plant-based prebiotic fiber that nourishes beneficial gut bacteria and promotes regularity.

Nearly one in three kids doesn't get enough magnesium from diet alone [1], and active, growing bodies lose electrolytes like magnesium and potassium through daily activity. 

Potassium is a particular gap: the USDA has flagged potassium as a nutrient of public health concern and requires it on the Nutrition Facts label because most people, including kids, don't get enough of it from food alone [2].

Growing Up ® Magnesium is a gentle, kid-approved blend of magnesium and fiber, made without added sugar, colors, or artificial junk.

What Makes Growing Up® Magnesium Different

• Made with real fruit – powered by real Actazin® green kiwifruit powder
• No added sugar – lightly sweetened with monk fruit
• No food dyes or artificial flavors – clean, kid-friendly ingredients
• Gluten-free and formulated to be gentle on sensitive tummies
• Kid-approved pink lemonade flavor that mixes easily into water 

Why Your Kid's Body Needs Magnesium + Minerals 

A few everyday factors make it hard for kids to get enough magnesium and potassium from food alone:

• Picky eating limits intake of magnesium-rich foods like leafy greens, nuts, seeds, and whole grains.
• Processed foods are often stripped of essential minerals during manufacturing.
• Soil depletion from modern farming practices means fruits and vegetables contain less magnesium than they once did [3].

These gaps can show up as low energy, occasional irregularity, or trouble staying hydrated during active days.

Growing Up® Magnesium helps supplement what a picky-eater diet and modern food supply often miss, delivering minerals kids need alongside prebiotic fiber that supports healthy digestion.

Growing Up® Magnesium supports growing kids with a science-backed blend of dual-magnesium (citrate and glycinate), potassium, prebiotic fiber, and real fruits such as Actazin® green kiwifruit powder.

What Is Magnesium and Why Does It Matter?

Magnesium is an essential mineral involved in hundreds of processes in the body, including muscle function, nerve signaling, and maintaining a healthy fluid balance.

• Kids ages 1–3 need about 80 mg of magnesium daily; ages 4–8 need about 130 mg; and older kids need even more as they grow [4].
• Survey data suggests a large share of children and adults fall short of recommended magnesium intake, particularly when diets rely on processed foods [3].
• Magnesium bound to glycinate or citrate is absorbed more efficiently than less bioavailable forms like magnesium oxide, and tends to be gentler on the stomach [5, 6].

Growing Up® Magnesium uses a glycinate and citrate blend, chosen for better absorption and gentler digestion than less bioavailable forms of magnesium.

What Do Electrolytes and Prebiotics Do?

Potassium and prebiotic fiber work alongside magnesium to round out hydration and digestive support.

• Potassium is an electrolyte that helps regulate fluid balance, especially important for active kids who lose minerals through sweat. It's one of the nutrients the FDA specifically calls out as underconsumed across the U.S. population [2].
• Actazin® green kiwifruit powder has been shown in clinical research to increase stool frequency and improve stool consistency, thanks to its natural whole-fruit fiber and prebiotic compounds [7, 8].
• Agave inulin is fermented by beneficial gut bacteria, helping support a healthy microbiome and regularity [9].

Studies on Actazin® kiwifruit-derived fiber and agave inulin show improvements in stool frequency, consistency, and gut bacteria balance.

Using Growing Up® Magnesium with Growing Up® Prebiotics

Many parents use Growing Up® Magnesium alongside Growing Up® Prebiotics, and it's completely safe to give kids both.

• Growing Up® Magnesium works more immediately, gently relaxing the bowel and drawing water into the gut to soften stool.
• Growing Up® Prebiotics works over time, feeding beneficial gut bacteria to support long-term, sustainable regularity.

Together, they offer both short-term and long-term gut support, which can be especially helpful for kids dealing with stubborn constipation or transitioning off daily stool softeners.

If your kid is new to either supplement, start with a lower amount of each and build up gradually. Some kids may experience mild gas or looser stools if too much fiber or magnesium is introduced too quickly.

Tips on Getting Started with Growing Up ® Magnesium

Step 1: Mix it Right

• For kids ages 1–3, mix 1 scoop or packet daily into 4–6 oz of water. 
• For kids ages 4+, mix 2 scoops or packets daily into 8–12 oz of water. 
• Add ice for best taste. 

Step 2: Timing is Flexible

• Give it at any time of day. Consistency in daily timing helps build the habit.

Begin Health Editor's Note:

• Growing Up ® Magnesium is designed for kids ages 1+ and is safe for daily use.
• If your kid is a picky eater or eats a lot of processed food, Growing Up ® Magnesium can help provide minerals like magnesium and potassium, which pickier eaters tend to consume less of. 
• If your kid is very active or prone to dehydration, the added potassium and magnesium can help support fluid balance.

Summary

Growing Up® Magnesium is a gentle way to support your kid's hydration and digestion, especially when picky eating or an active lifestyle make it hard to get enough minerals or fiber from food alone. We use real fruit powders like Actazin® green kiwifruit, no added sugar, and put it all together in a kid-approved pink lemonade flavor to make it an easy addition to their daily routine.
