About Natural Stacks

Natural Stacks is a hyper-specialized and hyper-effective nootropic supplement company that does things a little differently than most: they operate with complete transparency. In a world of snake-oil supplements and misleading marketing, this is a refreshing change of pace. 

Their products all focus on brain health optimization using only naturally sourced and fully traceable ingredients. It’s difficult to find any other company comparable to Natural Stacks since they’re carved out a new niche for themselves in the field of supplements.

They’ve earned a reputation as being trustworthy, effective, and safe.

Overview of Natural Stacks 

Founder’s Story

Natural Stacks was founded by Roy Krebs back in 2013. The company has grown leaps and bounds since then and maintains their home base in Seattle Washington. 

Natural Stacks has had some major exposure through publications including Forbes, Men’s Journal, Thrive Global, Natural Products Insider, Trendhunter and more.

Their products have also been endorsed by some prominent voices in the wellness industry such as Dave Asprey, Dr. Anthony Gustin, Katie Wells of Wellness Mama, Dr. Michael Lewis and several others. 

What inspired Roy to build such a successful company was his own experience with brain health concerns. Growing up playing football and practicing martial arts led to a history of concussions, and Roy noticed severe implications on his memory and ability to focus later on in life.

He took this problem into his own hands and began researching and developing ways to support his brain through nutrition and supplementation. When he found some life-changing nootropic substances, it eventually spurred the creation of Natural Stacks so he could share his findings with the world. 

Natural Stacks isn’t just for those with a history of head injury though. The brand is truly for everyone. Their motto” “better brain, better life” truly exemplifies how most people could stand to take far better care of their brain for life-changing effects.

It’s also why Natural Stacks doesn’t apply a one-size-fits-all approach to their supplements. 

Instead of creating a single or small handful of products with tiny amounts of countless nootropic ingredients, Natural Stacks has highly targeted products that can help optimize brain function in the specific ways each individual customer needs.

Natural Stacks Mission

Natural Stacks is clearly passionate about brain performance and brain health. Some of their products are designed to help increase focus and mood, while others can enhance sleep, and provide protective brain health effects for better overall health.

They thoroughly understand that one’s brain health directly impacts their experience of life, so caring for this often forgotten aspect of physical health is extremely important for overall wellbeing. 

On top of creating great products for brains, Natural Stacks also donates to the non-profit organization: Cure Alzheimer’s Fund. This group is one of the leaders in research working on slowing and reversing neurodegenerative diseases that impact millions of people worldwide. 

The final company value that very clearly comes across in the way they do business is their desire for clean, transparent, and safe ingredients.

Since products that fall under the category of supplements aren’t reviewed or approved by the FDA, Natural Stacks goes the extra mile to build customer trust by following the most thorough self-imposed quality control seen from any company in the industry. 

They are an open-source company, which means they have ingredient traceability, third party lab testing and full label disclosure free of proprietary formulations.  

Natural Stacks Products

Natural Stacks produces a wide range of products, all falling under the category of brain health supplements. They organize their products by benefit on their website with highly detailed labels signifying both the ingredients and effects of each one.

In addition to individual supplements, they also sell bundles or “stacks” designed to work together to enhance specific cognitive functions. This includes bundles such as “the zen stack”, “the motivation stack”, “the essentials stack”, “deep sleep stack” and several others. 

You can also build your own bundle to receive 15% off your order. Since the supplements only feature a few highly specific ingredients without much overlap, they’re designed to be “stacked” or used together for best results.   

The Natural Stacks website even has a free quiz to help customers discover which product or combination of products would best suit their personal needs.

Since the products cover such a wide range of brain health benefits, they can serve many different types of customers.

Those looking to improve their mental performance through better focus and energy will find the “mental performance stack” to be particularly helpful, while those concerned with overall health will likely appreciate the “essentials stack”.

Natural Stacks Pros & Cons

Natural Stacks has quite a few major advantages over their competitors, and a few minor drawbacks outlined below. 

Natural Stack ProsNatural Stack Cons
Effective at targeting specific aspects of brain health to allow for a highly customized routineGives immediate resultsFull ingredient transparencyNaturally sourcedAffordably priced3rd party testedMore difficult to understand which supplements are best compared to other brands with fewer optionsMay require more supplements for a comprehensive routine than other brands

The main concerns that could make alternatives a better fit is simply navigating the complexity of Natural Stack’s product lines. It takes a small amount of knowledge on brain health to know which options fit which needs, however their online quiz does simplify this process.

Natural Stacks Products Review

MagTech® Magnesium Review

Natural Stack’s MagTech® Magnesium is their number one selling product with 478 reviews giving it an overall 4.9/5 star rating. They’re so proud of this formulation that they actually decided to patent it, which means you won’t be able to find a highly comparable product anywhere else. 

Magnesium supplements are often used to help with sleep, energy and overall brain health (1). What makes this product particularly special however is the combination of magnesium glycinate, magnesium l/threonate, and magnesium taurate. 

Together, these 3 forms of magnesium can provide a calming effect, improve sleep, enhance memory and cognitive abilities, and even promote bodily relaxation. This makes it a useful addition to most people’s daily routine since an alarming number of people are deficient in magnesium.

The label recommends 3-6 capsules a day which works out to be 48-96% of the average daily goal for magnesium intake. The additional ingredients are minimal and natural and simply serve to provide a capsule shell for easy ingestion. 

All of their capsules are also vegan/vegetarian friendly, gluten-free, all-natural, and free of artificial colors. 

Dopamine Brain Food™ Review

The next best selling product from Natural Stacks is their Dopamine enhancing product. This is meant to be a cognitive performance and mood boosting supplement to be taken in the morning. It can reduce brain fog, increase motivation and essentially help you to have a productive day.

This makes it an enticing product for those with long to-do lists or anyone who takes their cognitive performance seriously. The product itself only contains a few simple ingredients: vitamin C, vitamin B12, folate, L-phenylalanine, betaine, tyrosine, and vitamin B6. 

These ingredients are all naturally found in foods and give the body the materials it needs to synthesize increased levels of dopamine (2). Low dopamine levels can show up as tiredness, inability to concentrate, and even feelings of depression. 

This product could be a great addition for anyone experiencing low levels, or simply those wanting to take their focus up a notch. Like all the other supplements, it’s vegan/vegetarian, gluten-free, and entirely natural.

NEUROFUEL™ Nootropic Review

Another best selling product from Natural Stacks is also targeted at productivity. The ingredients of the Neurofuel Nootropic are designed to enhance focus, alertness and memory. It combines acetyl L-carnitine, artichoke leaf extract, coleus forskohlii, L-phenylalanine, and vitamin B6 for a potent cognitive support.

This formulation is designed to increase the number of messenger systems in the brain to allow neurons to fire more rapidly and increase cognitive performance. It works differently than the Dopamine Brain Food Product, which means both could be used in tandem.

This may be especially helpful for students or anyone looking to quickly and effectively learn new information. It’s best taken on an empty stomach in the morning or early afternoon, and based on the 468 reviews online ranking it as a 4.9/5 stars product, it’s safe to say that it truly works.

Serotonin Brain Food™ Review

Another highly sought after product from Natural Stacks also comes from their Brain Food line. The serotonin boosting supplement is meant to enhance mood, provide stress-relief, and contribute to an overall high sense of wellbeing. 

Serotonin is a neurotransmitter that gets a lot of attention in the mental health sphere, and for good reason. Serotonin levels can significantly dictate the prevalence of depression and anxiety, or conversely adequate levels can promote overall feelings of happiness and calmness (3).

The Serotonin Brain Food supplement consists of just 5 active ingredients: L-tryptophan, magnesium glycinate, rhodiola rosea root extract, vitamin B3, and zinc glycinate. These ingredients can synergistically allow the body to optimize its own levels of serotonin naturally by providing many of the necessary nutrients involved in serotonin metabolism.

It’s safe to take long-term and can be combined with other products such as GABA Brain Food or Dopamine Brain Food from the same product line. 

Smart Caffeine® Review

Next up on the list of popular products at Natural Stacks is their caffeine supplement. Unsurprisingly, this product is designed to increase energy and support focus, but without the jitters and caffeine crash that usually comes with too much coffee.

This product combines green coffee beans with L-Theanine to help mitigate some of the downsides of caffeine use such as sleep disruption. Each capsule contains 100mg of caffeine which is a relatively standard amount for a cup of coffee. 

This supplement can be used in combination with other Natural Stacks products such as NeuroFuel for truly powerful cognitive boosting effects.

According to the hundred of reviews ranking this as a 4.8/5 star product, it does indeed provide a noticeable energy boost without any jitters or anxiety.
