As an expectant mother, you know how important your health is. It can be challenging to keep up with your regular fitness routine during pregnancy, especially during the first and third trimesters. A pregnancy-safe pre-workout supplement can help provide the energy, endurance, and focus needed to power through each workout during this exciting, but physically challenging time of your life. Mamasupps and Nutraubmp are two popular pre-workout supplements designed specifically for expectant mothers like you. 


When choosing a pregnancy-safe pre-workout supplement, it’s important to focus on the safety of ingredients, quality, effectiveness, and a formula that’s backed by science. Here’s a comparison of Mamasupps vs Nutrabump to help you decide. 


What Are Pregnancy Safe Pre-Workout Supplements?


During pregnancy, the most important thing you can possibly do is to prioritize your own health and the health of your baby. You might have been given a list of “red light” and “green light” OTC medications, foods, activities, and maybe even supplements. However, the list just covers the basics, which leaves you on your own to figure out the rest. 


If you’re already familiar with pre-workout supplements, then you likely know that some contain an incredibly long list of ingredients, along with high amounts of stimulants that aren’t good for expectant mothers or their unborn children. 


Digging through every pre-workout supplement on the market to find the one that meets your high standards, while checking off every box on the “pregnancy-safe” list is not only daunting but time-consuming. When you’re growing a whole new human, and finding time to work, who wants to spend that much energy researching pregnancy-safe supplements? 


Choosing a pre-workout supplement that has already been designated as “pregnancy-safe” is the easiest way to find the supplement that will meet your needs. Pregnancy-safe pre-workouts avoid ingredients like high amounts of caffeine, BCAA, and some individual amino acids due to an unknown risk profile.  


Pregnancy-safe pre-workout supplements contain ingredients that are safe, and support your body in the extra ways it needs during pregnancy. As amazing as the process is, that growing baby is using a lot of your resources and putting additional stress on your body. Pregnancy-safe pre-workouts help fuel your body, and improve endurance and performance, all while not adding any negative side effects for you or the baby. 


Currently, there aren’t many options for pregnancy-safe pre-workouts. However, there are two that stand out in the crowd – Mamasupps and Nutrabump. 


Mamasupps Vs Nutrabump Pregnancy Safe Pre-Workout Supplements 


The foundation of any pre-workout supplement is the ingredients it’s made from. To really understand what these two pregnancy-safe pre-workout supplements offer, and what sets them apart from each other, let’s take a deep dive into the ingredients of each. 


Mamasupps Ingredients 


  • Vitamin C: 150mg

  • Vitamin B6: 12mg

  • Vitamin B12: 200mcg

  • Choline: 250mg

  • Calcium: 180mg

  • Magnesium: 11mg

  • Sodium: 75ng

  • Potassium: 100mg

  • Citrulline Malate: 6000mg

  • Beet Root Powder: 2500mg

  • L-Arginine: 1500mg

  • Natural caffeine: 100mg 

  • Other ingredients: Silicon dioxide, natural flavors, citric acid, stevia


So, let’s take a look at these ingredients and discuss the benefits they offer. 


First, let’s talk about vitamin C. This vitamin is important in a pregnancy-safe pre-workout because it can help reduce muscle soreness, and as a result, improve fitness performance. We also know that our immune systems can take a bit of a hit during pregnancy, so a little extra vitamin C is a nice boost. 


Then, we have the B vitamins, which are wonderful for a great boost of energy. B vitamins are water soluble, which means even at high amounts, you’re likely to excrete what your body doesn’t use through sweat and urine. Vitamin B6 is also essential for fetal brain development and metabolism. 


Choline is a nutrient that is found naturally in foods like eggs, meat, dairy, and some cruciferous vegetables. It’s a nutrient that can help support neurological health and add that sharp focus and mental endurance needed to power through a pregnancy workout. 


It’s no secret that body composition changes during pregnancy, including fluid. Between amniotic fluid, and an increase in blood volume, staying hydrated at a proper level becomes more challenging. Pregnant women who are serious about their fitness should be equally serious about hydration. Mamasupps makes sure to add in sodium, potassium, calcium, and magnesium to support electrolyte balance. These nutrients are also important for preventing those awful leg cramps that like to pull you out of the little sleep you get during the third trimester. 


Beetroot powder is a pre-workout ingredient we’ve been seeing a lot more of lately. Beetroot is interesting because it contains nitrite, which isn’t of much use as a pre-workout. However, the body naturally converts it to nitric oxide, which is incredibly beneficial as it expands blood vessels which helps to get more oxygen moving through your body. 


Mamasupps does have a small amount of caffeine. The amount is low enough that this is considered a low-stim supplement. 


Nutrabump Ingredients 


Now, let’s look at the ingredients in Nutrabump’s pregnancy-safe pre-workout supplement. 


  • Vitamin B12: 500mcg

  • L-Citrulline: 3000mg

  • Beta-alanine: 2000mg

  • L-Arginine HCI: 1000mg

  • Taurine: 1000mg

  • L-Glutamine: 600mg

  • Caffeine anhydrous: 100mg

  • Other ingredients: Citric acid, silicon dioxide, natural flavoring, stevia, malic acid


Comparatively, the only vitamin included in Nutrabump’s formula is vitamin B12. Of the B vitamins, B12 is the rockstar of energy. If you’re lagging and not quite feeling like making it to the gym, a good dose of B12 will help get you there. 


L-citrulline is beneficial for increasing endurance during your pregnancy workouts. During pregnancy, L-citrulline is also beneficial for supporting vascular health. Nutrabump also included beta-alanine, which is an amino acid that is beneficial for improving performance, focus, and recovery. 


The issue is that the advice on beta-alanine during pregnancy is mixed. Several sources suggest that it should be avoided altogether, while others say that there’s no harm in small amounts. Nutrabump’s formula keeps it reasonably low, but it’s still best to consult your doctor and talk over the risks/benefits with them. 


In a pregnancy pre-workout, L-glutamine is effective for supporting muscles and their recovery. Fortunately, it’s also considered relatively safe for supplementation during pregnancy. 


Similarities & Differences Between Mamasupps and Nutrabump


When comparing the two formulas, there isn’t a tremendous amount of overlap between the two. Mamasupps is more heavily focused on supporting and enhancing physical performance through vitamins and nutrients that are well-recognized and have a strong reputation of being safe during pregnancy. The double dose of B vitamins, vitamin C, and multiple electrolytes are examples. The beetroot powder is a pregnancy-safe addition with a glowing reputation in the pre-workout supplement space. 


Nutrabump’s ingredient profile is more focused on traditional pre-workout supplement ingredients, perhaps wrangled in a bit to levels that are more suitable for pregnancy. Overall, their formula gets a thumbs up, although some ingredients, such as the beta-alanine, have mixed thoughts about its safety during pregnancy. 


Nutrabump’s ingredient list is also shorter, which can be a positive or a negative, depending on how you look at it. During pregnancy, simple is better and the fewer ingredients you need to keep track of, the better. However, the extra ingredients in Mamasupps are all beneficial and supportive of a healthy pregnancy, not just a successful workout. 


When it comes to caffeine, both Mamasupps and Nutrabump offer 100mg of caffeine, which is half of the recommended daily limit of 200mg per day during pregnancy. Still, not every pregnant woman can or should have any caffeine at all. If you’re sensitive to caffeine, or are concerned about the effects of it on your health and your baby, make sure to have a discussion with your doctor about the amount of caffeine that is appropriate for you. 


Now, let’s talk about taste. Currently, Watermelon Wave is the only flavor of pre-workout supplement that Mamasupps offers, but they do have a couple of new flavors expected to be released soon. Nutrabump is available in Pink Lemonade, Strawberry Kiwi, and Tropical Punch. 


In terms of price, a one-month supply of Nutrabump is $42.95 for a one-time purchase, with a discount offered for subscribe and save members. Mamasupps is almost identically priced at $42.99 for a one-month supply and also offers a discount for subscribe and save members. 


Why Mamasupps Stands Out as a Pregnancy-Safe Pre-Workout


So, there we have it. A comparison of Mamasupps vs Nutrabump. In our opinion, Mamasupps stands out as the obvious winner between the two for a few reasons. 


The quality of Mamasupp’s formula can’t be denied. It has been formulated to provide clean, smooth energy during pregnancy and support recovery. So many of the ingredients are not only supportive of endurance during a workout, but also endurance during pregnancy. Energy, nutritional support, immune support, and electrolytes are all incredibly important. 


Mamasupps formula provides energy with zero jitters, clean ingredients that are free from any artificial additives, and is GMP certified, as well as being made in the USA. Overall, Mamasupps has received overwhelmingly positive reviews from its community of users for both pre-pregnancy and post-partum. 


Of course, our opinion shouldn’t take the place of researching Mamasupps on your own and discussing the formula and its benefits with your healthcare provider. Mamasupps is a pre-workout supplement that can help you make the very most of this special time of your life.
