Natural Stacks: Reviewing the Natural Stacks Supplements

Natural Stacks is a nutrition supplement company that provides different kinds of supplements, all with an underlying primary purpose of improving brain health. The team at Natural Stacks, a big one, works towards providing their customers with brain-focused supplements to enhance overall health and wellness and always emphasizes not hiding any information or ingredients. They also have a small CBD line as they expand their product range.

Their mindset is that, whatever age you are, it’s crucial to have a brain that functions at peak capacity to enjoy life to the fullest. They pride themselves on the transparency of their products and ensure each customer can know exactly what they are consuming with full access to the ingredient list.

They also have a ton of scientific research in the description of each supplement to ensure their customers can adequately educate themselves on the benefits of each ingredient within the supplement. They even have links to scientific research to read the articles yourself to conclude the ingredients!

What are Natural Stacks Supplements?

Natural Stacks was born in 2013 by co-founders Roy Krebs and Ben Herbert. Roy began formulating mental enhancer supplements after watching his grandfather battle Alzheimer’s. A portion of Natural Stacks proceeds goes towards the Cure for Alzheimer’s fund in honor of his grandfather’s memory.

After launching its first round of products in 2013, the company generated seven figures in their first year of business – there is an interest in a brain-boosting supplement!

Natural Stacks Supplements

All supplements in the Natural Stacks roster implement several strict guidelines to ensure quality across the board. They only use ingredients sourced 100% by them, giving them total control of their entire supply chain. They claim to grow their ingredients with integrity and commit to providing the highest quality natural ingredients in their products. The company states that they are the world’s first open-source company meaning that they provide ingredient traceability, third-party lab testing, and full label disclosure with each of their products.

Along with Natural Stacks’ willingness to provide openness with their supplements, they are also partnered with Intertek, a highly respected ISO, ANS, and IEC accredited lab, to ensure their ingredients’ purity with each batch. None of their products contain proprietary blends, ensuring that the consumer knows precisely what is in each capsule and the ingredients’ quantity.

If you subscribe to any of the supplements for a monthly delivery option, you can save 25% on your purchase – and this rings true across the board for all supplements on the Natural Stacks roster. This is an excellent opportunity for returning customers looking to incorporate these supplements into their routines long-term.



This patented, brain-boosting supplement works to increase motivation and mental endurance, improve concentration and alertness, improve social ease and mood, and provides an enhanced ability to study and learn new information. Neurofuel does all this with the use of 100% natural ingredients.

There are 15 servings in each bottle that can seem low, but this product is meant to be used before heavy focus sessions and not a daily supplement. If you are taking it daily, it is recommended to take two days off each week.

Natural Stacks has an additional Neurofuel product that comes in a powder lemonade formulation. Provides the same benefits as the supplement in a convenient and delicious alternative. There are 20 sticks in each box ordered which would give you 20 servings of brain-boosting lemonade.


  • 1 Bottle: $29.95
  • 1 Box Lemonade packs: $44.95

MagTech Magnesium Complex


MagTech contains L-Threonate, Taurate, and Glycinate, which are considered some of the most bioavailable forms of magnesium. This supplement helps support healthy cognitive aging, learning, memory and promotes relaxation and better overall sleep. MagTech is also 100% chelated and optimized with amino acids to ensure that it provides you with every ounce of benefits.

The RDA for magnesium sits between 300-420mg. At three capsules per serving, and each serving only contains 48% of your daily magnesium allowance, you may need to double up if you are looking to reach the upper limit.

Just like the Neurofuel products, MagTech also comes in the lemonade drink option. There are 20 sticks in each box ordered, giving you 10-20 servings of MagTech lemonade.


  • 1 Bottle: $34.95
  • 1 Box Lemonade packs: $44.95

Serotonin Brain Food


Designed to support the body’s natural ability to produce serotonin, Serotonin Brain Food supports a positive mood, relieves stress, and promotes a sense of general well-being.

Using science-backed ingredients that have been proven to alleviate stress and anxiety, such as Rhodiola Rosea and magnesium, amongst other ingredients.


  • 1 Bottle: $39.95

Acetylcholine Brain Food


Acetylcholine Brain Food was created to support the body’s ability to produce acetylcholine, a neurotransmitter essential to good cognitive function. It provides the brain the building blocks it requires to increase production, improve balance, and maintain the activity of this critical neurotransmitter.

This supplement can provide you with improved attention to detail, decreased brain fog, better mental clarity, and faster thinking all around. Each serving size is three capsules, and you get a total of 20 capsules per bottle.


  • 1 Bottle: $39.95

Dopamine Brain Food


Dopamine Brain Food supports you to trigger your drive to work hard and succeed. This nootropic stack is made again to support the body’s natural neurotransmitter metabolism for increased mental performance.

The all-natural ingredients allow you to be at ease knowing that you are supporting your body without pumping it with chemicals. Dopamine Brain Food contains over 200% of your daily value of B6 and folate, over 500% of vitamin C, and a whopping 166,667% Vitamin B12.


  • 1 Bottle: $39.95

GABA Brain Food

This final brain food stack works to temporarily reduce the feelings of stress and promote sleep and relaxation. GABA Brain Food acts as a brake for the body’s instinct of excitement.

With no filler ingredients, this product is simple yet effective in promoting feelings of calmness and relaxation.


  • 1 Bottle: $39.95

MycoMIND – Brain Cell Optimizer


MycoMIND can help optimize your brain cells and is designed to promote the growth of new neurons and mitochondria (the powerhouse of cells).

Containing just two ingredients, this product packs an effortless punch. Lion’s Mane mushroom has been used for generations in Japan for its nootropic abilities, and BioPQQ works to enhance short-term brain performance and improve long-term brain health.

Bonus, there are 30 servings in this bottle!


  • 1 Bottle: $34.95

Curcumin with Organic Coconut Oil


Natural Stacks has developed its proprietary CurcuWIN ingredient to be incorporated as the primary turmeric extract in its Curcumin with Organic Coconut Oil product. They also have ginger extract, and together, these ingredients can improve inflammation, relieve pain, support immune function, and decrease nausea.

Research indicates that turmeric doses of anywhere from 500mg to 2000mg may be effective. At 250 mg per serving (2 capsules), this product is below the lower end of the dosage recommendation. However, you may still see benefits from this dosage.


  • 1 Bottle: $24.95

Antarctic Krill Oil


Antarctic Krill Oil is a natural anti-inflammatory that supports both brain function and muscle development. This omega-3 powerhouse is heavier on the DHA to ensure the brain is getting a significant boost.

This product also contains 300mcg of astaxanthin, which is considered one of nature’s most potent antioxidants. Krill oil is typically better absorbed by the body, and with astaxanthin, this product checks all the boxes.


  • 1 Bottle: $24.95



An exciting and unique product, BrainBiotic works as a probiotic but is designed to work on the brain-gut axis. Our guts are the body’s second brain and have the largest surface area and nerve network constantly exposed to the outside world.

The strains of healthy bacteria used in this product (like L. Plantarum and L. Helveticus) work as probiotics for the gut but also play a role in working to help alleviate symptoms of brain fog, stress and improves impaired memory and cognitive decline.


  • 1 Bottle: $29.95

Coconut Vitamin D3


Coconut Vitamin D3 plays an irreplaceable role when it comes to overall health. It can help reduce inflammation, increase immunity, regulate neuromuscular systems, and improve sleep and your overall mood. Not only that, but it’s a foundational building block for proper bone health and supports new cell growth.

Vitamin D is also a fat-soluble vitamin, which means that it is more easily absorbed when taken with a fat source – insert coconut oil. This product contains 100mcg of coconut oil, allowing for the 5,000 IUs of D3 to be more bioavailable for you to absorb. Bonus: You only need to take one capsule per day and get a three-month supply in each bottle!


  • 1 Bottle: $14.95

Smart Caffeine


This caffeine supplement includes L-theanine (that comes from green tea) to ensure you are getting all the benefits of caffeine without the jitters, crashes, or anxiety that can come with regular caffeine capsules.

  • 1 Bottle: $19.95


Just as the name suggests, natural Stacks provides some stacks where you can purchase some of the supplements together to get maximum benefits. These are great options to save some money if you are looking to buy a few different products at once.

Natural Stacks Plus

Natural Stacks also offers two CBD-based products in their line as well as a stack with both together. If you are someone who enjoys CBD products, this may be a section worth checking out!

If you subscribe to a monthly bottle with CBD products, you receive 15% off versus the 25% on the regular products.

Dream CBD


This CBD product features 450mg of CBD oil formulated with melatonin and lavender-infused olive oil to aid with sleep.

Dream CBD was created to help get you to sleep faster, keep you sleeping longer, and above all, wake up feeling ready to tackle whatever the day has in store. All you need to do is take 1-2 capsules approximately half an hour before you’re ready to go to sleep, to experience the benefits.


  • 1 Bottle: $44.95

Omega CBD


Omega CBD contains 300mg of CBD oil along with omega-3 oil from algae. Omega 3, although having tons of other anti-inflammatory benefits, can also act as a potent bioavailability enhancer for the main components of CBD (cannabinoids). This means that you can potentially reap more CBD benefits with adequate amounts of Omega 3s in your system.

Omega CBD contains more of a specific type of omega (DHA), which focuses more on brain health and has additional benefits to the cardiovascular and metabolic systems of the body. This product is also plant-based which is excellent for anyone looking to take a vegan supplement.

Natural Stacks Reviews: What Do the Customers Have to Say?

Although this at first seems like you can’t go wrong with these products, it’s important to remember that they will typically post the best reviews on a company’s website. Some of their products are also available on Amazon, and so we searched here for some diversity.

As with any supplement, results will vary between individuals as we all have different bodies, nutritional and supplemental needs, and goals. It’s important to remember to always consult with your doctor before starting a new supplement regime and do your research to ensure you are comfortable with the products.

Natural Stacks Supplements Recap

Natural Stacks, led by Roy Krebs and Ben Herbert, along with their extensive practitioner partner network, have made a name for themselves in the online brain-boosting supplement world. Their mission involves creating a company to fully support each customer’s cognitive health, all while providing a trustworthy lineup of supplements that people feel safe purchasing. They offer various products geared towards optimizing health but always having some brain-boosting benefits.

While all supplement companies have their promises and raving reviews, our team took it upon ourselves to honestly figure out whether or not the products Natural Stacks has created are worth spending your hard-earned money on.

Natural Stacks uses all-natural ingredients and provides you with tons of research explaining each of the ingredients. Each ingredient was laid out on the labels (thanks to no proprietary blends) and allowed all their customers to see exactly what they are using to create their supplements. Their capsules per bottle typically fell in the low end of the spectrum. This would mean that purchasing a bottle of Natural Stacks products would typically only give you enough capsules for less than a month.

When you spend your money on a supplement, you want to know you are for sure getting your money’s worth. Most other supplement companies provide enough capsules to last their customers at least one month. With that being said, not ALL the products were like that, but a large majority of them were and are something to think about if you are looking to give a product a try.

They have the option of purchasing bundles of products together, which is always a nice feature. This will give you a slight discount rather than buying each of those products separately. On some other supplement websites, you get the option of purchasing more than one bottle; Natural Stacks does not offer that option. You can either buy one bottle or subscribe for monthly delivery to continue receiving that bottle at a discounted price. Pricing overall seemed to be relatively on par with other supplements of similar usage; however, Natural Stacks seemed to more often than not have fewer servings per bottle. So, they were priced a little higher per serving than some other brands. With Natural Stacks, you only receive a 30-day money-back guarantee which doesn’t compete with some other brands that offer 60 and 90-day guarantees.

Natural Stacks Supplements Final Thoughts

Natural Stacks’ mission and overall business model is geared towards transparency with their customers and improving brain health. They have a relatively large group of happy, returning customers and provide good products with simple ingredient lists. Despite some of the downfalls of the brand stated above, when paired with proper diet, nutrition, and overall good health practices, Natural Stacks supplements can support your body and optimize brain health. If you are curious to try the products, always remember to do your research and consult with a doctor before introducing a new supplement into your body.
