The Many Ways PQQ Can Benefit Your Body and Mind

Pyrroloquinoline Quinone, commonly called PQQ, is a natural compound found in various plant-based foods and has gained significant attention in the health and wellness industry due to its potential benefits. PQQ is a coenzyme essential in cellular energy production, antioxidant protection, and neuroprotection.

In this article, we will explore the various uses of PQQ and the scientific evidence supporting its potential health benefits.

What is PQQ?

PQQ is a redox cofactor that is involved in electron transfer during cellular metabolism. It was first discovered in 1979 as a cofactor in the bacterial enzyme alcohol dehydrogenase. PQQ was later found in mammalian tissues, including the heart, brain, and liver. It is also found in parsley, kiwi, green peppers, and tofu.

PQQ's Benefits and Uses

Supports Energy Production

PQQ plays a crucial role in the production of cellular energy. It stimulates the biogenesis of new mitochondria, which are the powerhouses of cells. Mitochondria are responsible for producing ATP (adenosine triphosphate), the body's primary energy source. PQQ has been shown to enhance the efficiency of mitochondrial energy production, increasing energy levels.

Antioxidant Protection

PQQ has potent antioxidant properties, which protect cells from oxidative stress. Oxidative stress is caused by an imbalance between the production of reactive oxygen species (ROS) and the body's ability to detoxify them. It can lead to cellular damage and contribute to the developing of various diseases such as cancer, diabetes, and cardiovascular disease. PQQ has been shown to scavenge free radicals and reduce oxidative damage, protecting cells from harmful effects.

Neuroprotection

PQQ has neuroprotective properties, which means it can protect brain cells from damage and death. It promotes new neurons' growth and enhances existing ones' function. In animal studies, PQQ has been shown to improve memory, attention, and cognitive function.

Cardiovascular Health

PQQ has been shown to improve cardiovascular health by reducing inflammation and oxidative stress. It has been shown to reduce blood pressure, improve cholesterol levels, and protect against atherosclerosis and plaque buildup in arteries.

Anti-Aging

PQQ has been shown to have anti-aging effects. It stimulates the production of Sirtuins, a protein group that plays a role in aging and age-related diseases. In animal studies, PQQ has been shown to increase lifespan and improve overall health.

Skin Health

PQQ has been shown to promote healthy skin by reducing oxidative damage and stimulating collagen production. Collagen is an essential protein that provides structure and elasticity to the skin.

Mood Enhancement

PQQ has been shown to have mood-enhancing effects by promoting the production of serotonin and dopamine, neurotransmitters that regulate mood.

Immune System Support

PQQ has been shown to support the immune system by reducing inflammation and oxidative stress, which can compromise immune function.

Athletic Performance 

PQQ has been shown to improve athletic performance by enhancing mitochondrial function and increasing endurance.

Anti-Inflammatory 

PQQ has been shown to have anti-inflammatory effects by reducing the production of inflammatory cytokines and promoting the production of anti-inflammatory cytokines.

Effect on Mitochondria

PQQ has been proposed to support the health and function of the mitochondria, the energy-producing structures in cells. Here's what we know so far:

1. Antioxidant properties: PQQ has antioxidant properties, which may help protect the mitochondria from damage caused by oxidative stress. This is important because oxidative stress has been linked to damage to the mitochondria, which can lead to a range of health problems, including fatigue, muscle weakness, and brain fog.

2. Energy production: The mitochondria play a key role in producing energy for cells, and PQQ has been suggested to support this process. Some studies suggest that PQQ may help improve energy production by the mitochondria, which could help reduce fatigue and increase energy levels.

3. Mitochondrial biogenesis: PQQ has been shown to promote the formation of new mitochondria, a process called mitochondrial biogenesis. This could be important because our mitochondria can become damaged and less efficient as we age, leading to various health problems.

4. Protection against mitochondrial damage: PQQ has been shown to protect the mitochondria against damage caused by oxidative stress and other factors. This could help improve the health and function of the mitochondria over time, potentially reducing the risk of health problems associated with mitochondrial dysfunction.

It's important to note that these potential benefits of PQQ are based on early studies, and more research is needed to understand PQQ supplementation's effects fully. Additionally, the potential benefits of PQQ may vary from person to person, and what works for one person may not work for another.

Sources of PQQ

PQQ is found in small amounts in various foods, including parsley, kiwi, green peppers, and tofu. However, obtaining significant amounts of PQQ through diet alone is difficult. Therefore, supplements are the best way to ensure adequate intake of PQQ.

PQQ supplements are available in various forms, including capsules, tablets, and powders. The recommended dosage of PQQ is 10-20 mg per day, although higher doses have been used in clinical studies.

Dosage

The recommended daily dose of PQQ varies depending on the individual's age, weight, and overall health. Most supplements provide 20-40mg of PQQ per dose.

Customer Reviews

Some common themes emerged from customer reviews of PQQ from Amazon.com and iHerb.com:

1. Increased Energy: Many customers reported feeling more energized and focused after taking PQQ, especially when combined with other supplements like CoQ10. Some reviewers also noted that PQQ helped them overcome fatigue and improved their endurance during exercise.

2. Improved Cognitive Function: Several customers reported that PQQ helped them improve their mental clarity, memory, and focus. Some even suggested that PQQ helped them reduce brain fog and enhance their overall mental performance.

3. Enhanced Cardiovascular Health: Some customers claimed that PQQ helped them lower their blood pressure and cholesterol levels. Others suggested that PQQ improved their cardiovascular health by reducing inflammation and oxidative stress.

4. Other Benefits: Customers also reported other benefits of taking PQQ, including improved sleep, reduced inflammation, and better overall health.

Not all customers experienced these benefits; some reported negative side effects like headaches, dizziness, and stomach upset.

Side Effects

Here is a list of potential side effects of PQQ supplementation:

Digestive Discomfort

Some people may experience nausea, vomiting, and diarrhea after taking PQQ.

Allergic Reactions

PQQ may cause skin rashes and difficulty breathing in some individuals.

Drug Interactions

PQQ may interact with certain medications, such as blood thinners.

It's important to note that the side effects of PQQ supplementation can vary from person to person, and some people may experience no side effects at all.

Summary

Pyrroloquinoline Quinone, or PQQ, is a natural compound found in various plant-based foods that has gained significant attention in the health and wellness industry due to its potential benefits. PQQ plays a crucial role in cellular energy production, provides antioxidant protection, promotes neuroprotection, improves cardiovascular health, and has anti-aging effects. Additionally, PQQ has been shown to support the immune system, enhance athletic performance, promote healthy skin, and enhance mood.

While PQQ can be found in some foods, supplementation is the best way to ensure adequate intake. However, as with any supplement, it is important to talk to your healthcare provider before taking PQQ, particularly if you have underlying health conditions or are taking any medications.
