PKU Doesn’t Slow Down the Mullen Boys

Brady and Quinn drink PhenylAde® GMP Drink Mix and start owning their PKU diets

Do you remember the moment you got the call about your child having an inborn error of metabolism?

In this video, Allyson Mullen shares her heartfelt story about that moment. Her sons Brady and Quinn received classical Phenylketonuria (PKU) diagnoses, which scared Allyson at first. Allyson opens up about what she’s learned as a parent and how Brady and Quinn have started taking on responsibility for their PKU management.

Allyson also shares why the Mullen family made the move to PhenylAde GMP Drink Mix for the boys’ PKU formula. Spoiler Alert: Brady actually called this formula “delicious,” and mom Allyson loves it because the formula contains glycomacropeptide (GMP). GMP is made from a whole protein source, and Nutricia’s PhenylAde GMP Drink Mix has a creamy, mild vanilla flavor with a smooth drinkable texture. It is also available in an original plain flavor.

Watch now to hear more about Allyson Mullen’s proud moments and why her boys love PhenylAde GMP Drink Mix.

“PKU is a family thing:” Lacy talks about raising her daughter Aspen

“When I got the call, I couldn’t process what I was hearing. It was so hard.”

Lacy thinks back to the moment when she learned that her second child, a baby girl named Aspen, was diagnosed with Phenylketonuria (PKU).

PKU is a rare inherited metabolic disorder that means a person must avoid foods naturally high in protein (such as meat, eggs, and even bread). This is done to avoid a build-up of a substance known as phenylalanine in the brain, which is harmful to people with PKU.

Lacy, her husband Darryl, Aspen (now 2 years old), and their other child, Finn (6), live about an hour from New Orleans, Louisiana. Caring for a little one with PKU can be tough, as new parents and families like Lacy’s will know.

“You can’t wing it,” Lacy says, since the diet must be closely monitored to support the baby’s proper growth and development. Darryl and even brother Finn are involved in Aspen’s care, looking after her to see she has the right foods and consumes her PKU-appropriate protein. As part of the PKU diet plan set out by her healthcare professional, Aspen gets essential nutriends and protein by drinking her PKU formula.

“It’s almost like Darryl, Finn, and I also have PKU for the first five years [of Aspen’s life],” shares Lacy. “PKU is a family thing.”

Lacy and the family are especially focused on making sure Aspen gets the proper amount of formula to help her grow and develop. From birth up until now, Aspen drank Nutricia’s PKU Periflex® Early Years, which her metabolic healthcare team recommneded. This formula is complete with DHA & ARA for brain development and prebiotics, which support immune and digestive health.

Learn more about Early Years metabolic infant formulas here.

Aspen now drinks PKU Periflex Junior Plus as her next-stage formula. (Learn more about Periflex Junior Plus here.)

“I try not to make drinking formula a job for Aspen. I leave it out for her and let her have it in her own time.” This is one of Lacy’s tips as far as encouraging a positive relationship between children and PKU formula.

PKU can feel isolating for Lacy and the family since not many other people in their community know what PKU is or how to care for Aspen. So, to connect to other parents with children with PKU, Lacy turned to social media.

She connected with families all over the world, from Ireland to Canada, and she found a fellow mom named Kellie from Connecticut. Lacy and Kellie bonded over the realities of daily life with a new baby with PKU. According to Lacy, Kellie has been “a life saver.”

“We’ve overcome a lot,” shares Lacy, thinking about how she and her family have learned more day-by-day on how to best nurture Aspen. She knows what the high’s and low’s are like, and that’s why she wants to be involved with the PKU community. If she notices a new parent on one of the Facebook support groups, she immediately reaches out to them via private messenger.

“If I can help that person through even one minute, I will. I’ll write to them.”

It’s the spirit of “in this together” that has helped Lacy and her family to where they are today and what she hopes to see throughout the broader PKU community.

We do our best to provide support and education for families like Lacy’s. Take a look at our Learning Center page for disorder-specific videos, booklets, and more. We’re here for you and your family.

If you are a new parent and are interested in learning more about the metabolic formula Aspen used as an infant, see more on Early Years formulas here or ask your metabolic healthcare team.

Learn how Rene returned to the PKU diet as an adult

Being off the PKU diet leads to high phenylalanine (PHE) levels and is associated with a variety of symptoms, such as feeling tired, irritable and forgetful.  This is how Rene felt before he went back on the PKU diet as an adult.

We met up with Rene in his home in San Diego, CA to learn more about why and how he returned to the PKU diet at age 36.

“My name is Rene and my entire life, I’ve had PKU.  I was good on my diet as a kid, because my mom and aunts all helped making my food, teaching me how to cook and reminding me to take my formula.  As I got older it got harder to stay on diet and one day I just gave up.”

Rene shared that the most difficult time was in his teen years, since he was completely off diet.

“I was feeling tired most of the time. It was hard to be active and I did not do well in school. It was hard to memorize stuff. I just wasn’t myself.  I was always angry.”

So we wanted to know why Rene decided to come back to diet as an adult.

“One of the big motivations that I had was my daughter. I wanted to be a better role model and be there for her more.  I am a single dad, and when I was off-diet I didn’t really have energy to play with her, help her with homework.  When I look back, I yelled a lot, too.”

“I just decided I needed to be a better parent so I can go to work and still have energy to focus on her (my daughter).”

We know it is not easy to get back on the PKU diet after being off diet for several years, so we wanted to know how Rene did it.  What were your first steps?

“One day, I said okay, I’m just going to call my clinic and make an appointment.  Then I had my first doctor appointment to get on the diet and get my PHE levels down.  Due to my insurance I had to drive all the way to Los Angeles, but I had my daughter with me for motivation and it was a good appointment.”

“The clinic said that there were several new options in PKU formula and they taste way better then they did when I was a kid.  They gave me the PhenylAde® GMP Ready so I’m like okay, I’m going to give it a try.” “The PhenylAde GMP READY was great. I actually love it. I don’t have to scoop it or anything.  I can take it to work. I can take it anywhere. It’s really smooth, it’s really tasty. It doesn’t have an aftertaste.”

Rene also told us that he likes to cook and remembers several vegetarian recipes his aunts taught him as a child.  He shared some recipes with us as he made lunch for himself and his daughter.

“Now that my PHE levels are back in range, I feel way better. I’m more active. I’m going to the gym, working out, playing soccer, and I also play with my daughter now, which I was not doing before”. 

We were curious if Rene had any advice for other adults with PKU who may be thinking about returning to the PKU diet.

 “Find a motivation and really focus on that.  Returning to diet is not something that happens overnight, you do need to work at it and plan your meals a bit more than when you are not on diet. The impact is you have a little bit more control of your highs and lows when sticking to the diet.  I’m really glad I did it. I feel way better.”

“You should also give PhenylAde GMP READY a try, it’s awesome, not what PKU formula used to taste like. For me it was a life-changer.”

Upcycling Nutricia Cans

Wait, wait! Don’t throw out your formula can yet!

You can reuse your Nutricia Metabolics formula cans for arts & crafts and more! First, fully clean out the can. Second, follow our easy and fun tips below.

Be sure to clean your cans out thoroughly before reusing them. We recommend wiping out the cans with a damp towel. Let them sit out until they are 100% dry. You’re ready to give them a new life!

Pot for Flowers and Plants

Decorate the outside of the Nutricia can and carefully poke a hole at the bottom of the can to allow for drainage. Fill with potting soil and plant flower seeds or re-pot another plant.

Musical Instruments

Interested in crafting a set of maracas or drums? Take the plastic lid from the can and grab a pair of sturdy sticks and start drumming right away! You can also make a maraca out of Nutricia cans by adding beans or pebbles for a neat sound effect.

Piggy Banks

Turn an empty Nutricia formula can into a cute piggy bank for your child or even for yourself! Paste pictures of your kids onto the outside, and then use a box cutter to create a small rectangular cutout in the plastic lid. Then, start saving!

Decorative Storage

Use old Nutricia cans to hold toys such as building blocks, marbles, or toy cars. You can also reuse formula cans to keep your scrapbooking or craft items in one place.

Re-used Nutricia cans make great storage containers for buttons, ribbons, safety pins, beads and other small items you have lying around. You can even print out pictures of these and then use them to decorate the outside of the can. Customize the outside of the can with printed pictures of what’s stored inside.

Holiday or Birthday Gift Basket

Paint the outside of the Nutricia can for the holiday season or someone’s birthday, and fill with treats, holiday goodies or a personal gift. Think about attaching a handle for easy carrying.

And More: playsets, headband organizers, teacher gifts!

Re-used cans are able to be repurposed into so many crafts and activities for your family. If you have used your Nutricia packaging in a creative way, comment below. We would love to learn from you!
