3 Red Flags of Vitamin Deficiency in Teens
And how this science‒backed gummy vitamin is changing parents' lives.
Red FLAG #1
Moodiness & Irritability
Behavioral issues aren't always just a phase—they can be a sign of nutrient deficiencies. For example, Vitamin B deficiencies can affect mood, and low vitamin D levels can lead to irritability.*
🟢 A well‒rounded supplement can help restore balance, calming the brain, supporting emotional regulation, and boosting mood.*
Red FLAG #2
Always Tired & Uninterested
If your teen has low energy or struggles to stay awake in class, it may be linked to deficiencies in B vitamins, vitamin C, and magnesium. These help produce energy to power your teen’s brain and body.*
🟢 Supplementing with the right multivitamin can help replenish those gaps, making it easier to stay alert and energized throughout the day.*
Red FLAG #3
Staying Up Late
Poor sleep could be more connected to nutrition than most people realize. Vitamins like B6, B12, and D3 play a crucial role in regulating your teen’s sleep‒wake cycle. For example, Vitamin B6 supports melatonin production, which is the hormone that signals it’s time to sleep.
🟢 A daily multivitamin that includes these nutrients can help promote relaxation and restful sleep.*
Luckily, there’s finally a science‒backed way to fill those nutrient gaps!
(plus, it’s doctor‒recommended and teens love it!)

Super satisfied
I kept seeing these vitamins on my social accounts and I was skeptical at first. I finally gave in and bought some for my son. He loves the taste of these and begs to eat them all day. It has only been a month, and so far, I am very satisfied with these gummy vitamins.

This has been the easiest multivitamin for my teen to take! The gummies are very tasty and they are happy to not have to try swallowing a big capsule. Plus my teen is glad to get all of those important vitamins and minerals in just two gummies because they hate having to take a bunch of supplements!
