Magnesium at the Right Time: Frank Suarez's Teaching on the Excitated Nervous System, Metabolism, and Sleep

Introduction

Many people take supplements, change their diet, or try to improve their health without first pausing to consider a basic question: how is their body functioning internally? In Frank Suárez's teachings, this question was not a minor detail. It was the starting point.

In this MetabolismoTV explanation, Frank Suárez presents a specific observation about magnesium: it's not just about taking it, but also about taking it at the right time, especially when a person has an overactive nervous system or problems related to low stomach acid production.

The central lesson is not simply “take magnesium.” The deeper teaching is that the body functions with order, with rhythms, with individual differences, and with a nervous system that influences everything that happens in metabolism.

Frank taught that, to improve metabolism, one must first understand the body. And in this case, understanding the body means observing the nervous system, digestion, timing, and how the body processes what it receives.

Key Points

• Frank Suárez taught that the nervous system directly influences metabolism, digestion, sleep, the immune system, and detoxification.
• Not all bodies function the same way: some people have a more excited nervous system, while others have a more passive one.
• Magnesium was presented by Frank as an important aid, but he also explained that it must be properly digested for the body to use it.
• According to his teaching, people with an excited nervous system or hypothyroidism may produce less hydrochloric acid.
• Frank explained that after 6 p.m., the body prepares for sleep and may digest poorly, especially in people with an excited nervous system.
• The practical recommendation was to take magnesium at 6 p.m. or earlier if taking it late activates the person instead of helping them sleep.

The Nervous System: A Key to Understanding Metabolism

Frank Suárez begins the explanation by recalling one of his most important teachings: we all have a dominant nervous system. Some people have a more passive nervous system, while others have a more excited nervous system.

He himself mentions that his body had a passive nervous system. In contrast, he points out that his wife Elizabeth, his mother, and Jorge, who was behind the camera, had an excited nervous system. This distinction, according to Frank, was not a minor matter or a curiosity. It was one of the keys to understanding why each body responds differently.

In his simple way of explaining, Frank said that doctors call the passive system “parasympathetic,” but in his teaching, he presented it as “passive nervous system.” He also spoke of the “excited nervous system” to refer to a body that tends more towards activation.

From that base, Frank taught that one of the major influences on metabolism lies in the nervous system. He described it as a kind of wiring that, from the brain, manages what happens in the body. If that wiring is tangled or malfunctioning, he said, then important areas such as:

• metabolism;
• digestion;
• sleep;
• the immune system;
• the defense system;
• liver detoxification.

In simple words: for Frank, if a person wants to control their metabolism, they must pay attention to the nervous system.

Not all bodies function the same way

A very important part of this teaching is that Frank did not speak of the human body as if all were the same. On the contrary, he insisted that each person has a dominant type of nervous system, and that knowing it helps to choose foods better and obtain better results.

To explain it, he uses a very clear comparison: there are cars that run on gasoline and others that run on diesel. Both have an engine, but the fuel is not the same. According to Frank, something similar happens with bodies. The body needs to receive the correct type of food according to its type.

This comparison summarizes a central idea of his philosophy: the problem is not always that the person “is not trying hard enough,” but that perhaps they do not understand what type of body they have.

That is why Frank invited people to identify whether they had an excited or passive nervous system, mentioning episode 199 of MetabolismoTV, where he asked five questions to help recognize it.

As he explained, if a person answered “yes” to any of those five questions, they had an excited nervous system. If they answered “no” to all of them, they had a passive nervous system. Frank presented it as something simple, but crucial for health, for choosing foods, and for achieving results.

The teaching here is clear: knowledge of one's own body changes the way one cares for it.

Magnesium as an important aid for the body

After explaining the role of the nervous system, Frank delves into the main topic of the episode: magnesium.

According to his teaching, one of the main aids for improving health is magnesium. At NaturalSlim, he explains, they used a special magnesium called Magic Mag, which he describes as well-absorbable. But he also clarifies something practical: if the person does not have access to that product, they can use any magnesium, because "any magnesium is better than no magnesium," always within the context of what he is explaining.

Frank presents magnesium as an essential mineral and relates it to various functions and conditions: diabetes, blood pressure, bone loss, osteoporosis, sleep, constipation, depression, and back pain.

He also states that magnesium is the most deficient mineral according to studies conducted in populations and mentions an estimate by the World Health Organization regarding magnesium deficiency.

But what is important in this blog is not to add more explanations than Frank gave. What sustains this teaching is that, for Frank, magnesium was an important aid because many people do not consume enough vegetables, salads, and fruits, which he identifies as sources of magnesium.

Instead, he observes that many people consume bread, flour, rice, potatoes, and sweets, but few vegetables or salads.

From that observation, Frank connects a daily habit with an effect on the body: when the body lacks what it needs, metabolism and health are affected.

The discovery: magnesium doesn't work the same for everyone if taken late

The most interesting part of the teaching is the observation that Frank says he discovered after using magnesium for many years at NaturalSlim and working with many people.

He noticed something that at first made him curious: for some people, magnesium didn't make them sleepy. On the contrary, it woke them up or activated them.

Frank explains that this occurred in a minority of people, but it was enough to make him search for the reason. And here appears a characteristic very typical of his way of teaching: he was not satisfied with saying "just because." He wanted to understand the cause.

As he explained, the body works on a cycle called the circadian cycle, like a kind of internal clock.

Magnesium is a mineral, and as a mineral, Frank describes it as a difficult metal to digest. For the body to use it, it must first pass through the stomach and be digested.

Hydrochloric acid: the key to digesting magnesium

Frank explains that the stomach produces hydrochloric acid, a substance that allows the digestion of minerals like magnesium.

He also says that when a person eats something heavy or dense, if they don't have enough hydrochloric acid, they cannot digest it well.

Then the question changes. It's no longer just: "Do I take magnesium?"

The question becomes more precise: can my body digest that magnesium at the time I'm taking it?

Excited nervous system, hypothyroidism and low acid production

Frank connects the topic of magnesium with two situations: the excited nervous system and hypothyroidism.

As he explained, people with an excited nervous system or hypothyroidism may have a condition that Frank calls hypochlorhydria. He explains that "hypo" means low, and "chlorhydria" refers to hydrochloric acid. In simple terms, it means low acid production in the stomach.

According to his teaching, when a person has an excited nervous system or thyroid problems, they may produce little stomach acid to digest things like magnesium.

But Frank adds a key detail: after 6 p.m., acid production stops functioning in the same way because the body prepares for sleep and no longer digests well.

Therefore, according to his explanation, people with an excited nervous system may have sleep problems if they eat late at night.

In contrast, he contrasts this with those who have a passive nervous system, as he describes himself. He says that a person with a passive nervous system can eat something heavy late and still sleep.

The teaching is not that everyone should do the same. On the contrary, Frank returns to the idea that we are all different. What works for one person may activate, bother, or prevent another from resting.

Why the timing of magnesium can change the outcome

The central discovery of the episode is this: for some people, especially those with an excited nervous system, magnesium should be taken earlier.

Frank explains that if a person wants magnesium to have the expected effect and not wake them up, they need to digest it. And to digest it, they need enough acid in the stomach.

Since, according to his explanation, that production decreases after 6 p.m., he recommends taking it at 6 p.m. or earlier: at 5, at 4, or at an earlier time.

In that way, the body would still be producing acid, could digest the magnesium, and the person could receive the benefits Frank is describing.

The practical idea is simple, yet powerful: sometimes the problem isn't the magnesium, but the time it's taken.

Frank says that, after understanding this, the people who were previously woken up by magnesium could now sleep, because the timing was adjusted.

In the NaturalSlim approach, magnesium can be part of a broader strategy to support metabolism, always accompanied by knowledge, correct habits, and observation of one's own body.

The importance of observing the cause, not just the effect

This episode also shows one of Frank Suárez's most consistent teachings: seeking the cause.

He observes an effect: some people take magnesium and become activated instead of sleeping. But he doesn't stop there. He looks for the reason. He relates the effect to the nervous system, the body's cycle, digestion, stomach acid, and timing.

This way of thinking is very characteristic of his teaching. For Frank, the body was not a collection of separate symptoms. It was a living, connected system, where metabolism, sleep, digestion, and the nervous system all influence each other.

That is why his message does not stop at a loose recommendation. It becomes a lesson in knowledge: before deciding what to do, the person needs to understand how their body works.

Conclusion: Knowledge allows for better habit adjustment

Frank Suárez's teaching can be summarized as follows: magnesium can be an important aid, but for people with an excited nervous system or difficulty digesting it, the time it is taken can make a big difference.

Frank does not present the body as a machine that is the same for everyone. He presents it as a living organism, with rhythms, with differences, and with specific needs. That is why he insists on knowing the type of nervous system, observing digestion, and respecting the body's natural schedule.

Instead of treating a symptom in isolation, his approach leads the reader to look at the cause:

• what type of nervous system dominates my body?;
• how is my digestion?;
• at what time am I taking what I want to help me?;
• is my body prepared to process it?

That is the value of this teaching: it is not just about taking something, but about understanding metabolism.

Because, in Frank Suárez's philosophy, change begins with applied knowledge. And when a person better understands their body, they can adjust their habits with more intelligence, more order, and better results.

Frequently Asked Questions

What is the best time to take magnesium according to Frank Suárez?

According to Frank Suárez, if a person has an excited nervous system or difficulty digesting magnesium, it is best to take it at 6 p.m. or earlier. The reason is that the body would still be producing acid to digest it better.

Why can magnesium wake some people up?

Frank explained that some people are activated by magnesium when they take it late because they don't digest it well. In his teaching, this can be related to low hydrochloric acid production, especially in bodies with an excited nervous system.

What does the nervous system have to do with metabolism?

Frank taught that the nervous system functions as wiring that influences metabolism, digestion, sleep, the immune system, and detoxification. That is why he said that to control metabolism, one must observe the nervous system.

What is the excited nervous system?

In Frank's teaching, the excited nervous system describes a body that tends more toward activation. This type of body can react differently to foods, supplements, schedules, and habits, which is why it is important to know it.

What is hypochlorhydria according to Frank Suárez?

Frank explained that "hypo" means low and "chlorhydria" refers to hydrochloric acid. In simple terms, hypochlorhydria is low stomach acid production, which can make it difficult to digest minerals like magnesium.

Why did Frank relate magnesium to vegetables?

Frank pointed out that magnesium is found in vegetables, salads, and fruits. According to his observation, many people eat bread, flour, rice, potatoes, and sweets, but few vegetables, which is why they may have a magnesium deficiency.

Is Magic Mag mandatory to follow this teaching?

No. Frank mentioned that at NaturalSlim they used Magic Mag because it was well absorbed, but he also clarified that if a person did not have access to that product, they could use any magnesium within the context of his explanation.

What is the main lesson of this episode?

The main lesson is that it's not enough to take magnesium. One must understand the type of nervous system, digestion, acid production, and the time of day when the body can process it best.
