Aging is inevitable and can impact many aspects of your health and lifestyle. Aging can be accompanied by stiffening joints, decreased energy, increased susceptibility to disease, and more. In addition, the elderly are much more likely to be diagnosed with heart disease, experience a stroke, and develop cancer. In recent years, anti-aging products and therapies have been a hot topic and have been gaining significant publicity.

There are many anti-aging products that are currently available. They boast a variety of benefits from improved skin complexion and cellular health, to better fitness and reduced joint pain. One of the products that is garnering more and more attention is the drug metformin, but can this medication really provide benefits to slow the aging process?

What Is Metformin?

Metformin is generally used by individuals with type 2 diabetes to help control blood glucose levels.

This medication works by reducing the amount of sugar, also known as glucose, released by the liver. In addition to lowering the overall sugar levels in the blood, metformin also helps to increase insulin sensitivity.

Insulin sensitivity is the ability of insulin to take glucose out of the blood and into the cells. Low insulin sensitivity correlates to reduced insulin effectiveness and increased blood sugar levels. Taking metformin may take four to five days to see optimal results. It is often used in conjunction with dietary changes and exercise programs.

How Does Metformin Work?

Metformin is a part of the class of drugs known as biguanides, which inhibit the production of glucose in the liver.

The body transforms glucose into glycogen so that it can be stored in the body on a long-term basis. The liver contains glycogen stores, and when the body is low on energy, it can trigger the liver to break down glycogen to produce glucose.

The liver also produces large amounts of glucose through a process known as gluconeogenesis. This process generates glucose by breaking down sources besides carbohydrates, such as amino acids, lactate, and glycerol.

Generally, this process works well; however, with type 2 diabetes, the effectiveness of insulin is decreased. The body has trouble taking glucose from the blood and transporting it into the cells. Insulin is released from the pancreas, and when cells don’t allow glucose to enter, it is known as low insulin sensitivity. When prolonged, this leads to chronically elevated blood glucose levels, worsening diabetes, and a variety of other health issues.

How Popular Is Metformin?

Metformin is used by around 120 million people around the world, and its wide availability, lack of severe side effects, and affordable cost contribute to its usage. This medication is becoming even more popular due to the various other benefits it can produce.

Why Would You Take Metformin for Anti-Aging?

With age, various health issues can arise as the body begins to break down. However, while aging itself cannot be considered a disease, it is linked to a variety of other processes that can lead to significant health conditions and reduce your life expectancy. Diseases are an especially significant contributor to death rates in industrialized and developed countries.

Because of this, slowing the aging process can help reduce the risk of being diagnosed with potentially harmful diseases and conditions in the future.

While metformin is primarily used to treat type 2 diabetes, research has shown it has the ability to protect the body against a variety of other diseases as well.

Some of these include cancer, inflammation, cognitive decline, dementia, diabetic nephropathy, and more.

In addition to the protective effects, metformin has also been shown to prolong life and promote longevity.

Studies with human subjects have confirmed preliminary results from animal studies. Specifically, multiple studies have examined diabetic and cardiovascular patients and have shown that metformin increased life expectancy, decreased frailty, and reduced risk of dementia and memory loss.

Studies on Metformin

Metformin has been extensively studies, and there are many positive results. Here are the most notable.

1. Metformin: A Hopeful Promise in Aging

Research by Cold Spring Harb Perspect Med. published 2016

Over the last several years, many drugs have been identified as having anti-aging properties and shown promise to promote life extension; one of these drugs is metformin. Cold Spring Harb Perspect Med completed a comprehensive review of various studies, examining the ability of metformin to slow the aging process.

The authors noted that metformin causes a number of therapeutic effects, and this profile makes it an ideal candidate for promoting reverse-aging effects. Initial tests were done in worms, mice, flies, and rats. Many studies on these populations have demonstrated significant improvements in lifespan with long-term metformin ingestion. These same benefits have been seen in humans as well.

2. Repurposing Metformin: An Old Drug With New Tricks in Its Binding Pockets

Researched by Biochem J. Published 2015

In 2015, an article published in the Biochemical Journal examined metformin’s use as an anti-aging strategy. The authors examined the cellular processes and impacts of metformin throughout the body. They also collected data from many studies on insects, animals, and human subjects.

After examining all available data, they found that there was evidence from several organisms that demonstrated significant potential for metformin to be used as an anti-aging strategy. While many possible benefits of metformin have been researched, the authors noted that there are many others that likely have yet to be discovered and that further research is required to establish the full range of benefits metformin may offer.

3. Metformin – Do We Finally Have an Anti-Aging Drug?

Researched By Cell Cycle. Published 2013

In 2013, Vladimir Anisimov published a study examining the role of metformin on the aging process. The author noted that there are nine hallmarks of aging in mammals, including genomic instability, mitochondria malfunction, stem cell destruction, decreased cell-to-cell communication, and others.

He also described that it appears that metformin has the ability to positively impact all nine of these factors. Some potential benefits of metformin that have been found in studies include improved DNA formation and repair, reduced cell mutation rates, lessened cellular stress, and many more. Anisimov further notes that in addition to anti-aging potential, metformin also has shown promise in its ability to slow or stop cancer progression.

4. Metformin as a Tool to Target Aging

Researched by Cell Metab. Published 2016

Due to the evidence that exists supporting metformin as an anti-aging drug, four authors proposed a study design to further evaluate this medication’s potential benefits. The authors noted that health span, which is the time of a person’s life in which they are fully functional and free of chronic illness, was the main outcome to be evaluated.

The authors emphasize the various bodily processes that metformin can benefit, including decreased insulin levels, reduced DNA damage and enhanced repair, lessened inflammation and cell self-destruction, and many more. However, there is still uncertainty regarding the method of impact, being whether metformin impacts multiple pathways and systems simultaneously or effects just a single pathway that trickles down to other processes as well.

Initial studies, especially those done in rodents, provided promising results, demonstrating lifespan increases of 14 percent when metformin was taken starting early in life. Other studies have shown similar increases as well, ranging from four to 20 percent.

However, not all studies had positive results on lifespan. But, after looking at results, it appears that the range of benefits may be related to the dose of metformin provided. This proved to researchers the importance of establishing an effective dose that was not toxic to the human body. After examining all clinical trials, the authors noted that a dose of up to 1,600 to 1,700 milligrams per day is the maximum dose needed to elicit the desired results.

5. TAME: Targeting Aging with Metformin

Researched by the American Federation for Aging Research. Trial is ongoing

The Targeting Aging with Metformin (TAME) Trial is an ongoing research project based on the previous study’s outline and findings. This trial design involves enrolling 3,000 individuals between the age of 65 and 79 for evaluation, and the estimated completion date for the trial is August 2024, lasting a total of six years. Currently, there are 14 different sites across the United States that have been secured and are involved in the trial.

Administering metformin to these individuals will then allow researchers to evaluate outcomes related to heart disease, cancer, dementia, diabetes, Alzheimer’s, and mortality. The study’s goal is to gain approval from the Food and Drug Administration for metformin to be a usable treatment with benefits directly related to aging.

Every medication has side effects, and with Metformin, it is no different. This medication can also have other affects on the body including the following:


While taking Metformin, it can cause all exercise to not have any results
One potential concern with metformin is its effect on exercise. One study in 2018 examined the potential effects of metformin and exercise when used together. It is well known that exercise has protective effects on the heart and lungs and improves insulin sensitivity. Exercise can reduce the incidence of heart disease, lung disease, diabetes, and more.

However, when metformin is used in conjunction with exercise, researchers found that the typical effects of exercise were diminished. The study involved two groups. Both groups received the same exercise training, but only one group received metformin treatment in addition to the training.

The exercise-only group demonstrated improvements in insulin sensitivity and better respiratory function; however, metformin reduced the magnitude to which these benefits were seen. Because of this, more research must be conducted to establish if metformin has an antagonistic effect when used with exercise.


It can cause B12 problems. You can take a B12 supplement to counteract.
Another potential issue with metformin is that it has a permanent negative effect on your body’s ability to absorb vitamin B12. This vitamin plays a critical role in preserving brain function, preventing dementia, improving artery health, and regenerating damaged and destroyed cells.

If you do decide to take metformin, it is critical that you take a high-quality vitamin B12 supplement, preferably in methylated form. This will ensure that your body is still able to obtain an adequate amount of this nutrient, negating any potential negative effects.

When Should You Not Take Metformin

Metformin is contraindicated if you suffer from several different health conditions. You should not use metformin if you have moderate to severe kidney disease, advanced liver disease, metabolic acidosis, or diabetic ketoacidosis. In addition, you should not be taking metformin if you require an x-ray or CT scan that involves injecting dye into your veins.

Metformin is broken down in the kidneys, and this can result in kidney dysfunction when the medication is taken on a long-term basis or at high dosages.

Because of this, if you have serious existing kidney issues or are receiving dye, which must be broken down by the kidneys, you should avoid taking metformin. Metformin also affects liver health by inhibiting certain enzymes that reduce functionality. We’ll discuss more about the effects of acidosis later on.

Side Effects

Metformin generally causes mild side effects. Usually less than other drugs similar to it
Compared to many other drugs used for similar purposes, metformin has very few associated side effects and is quite safe to take. However, there are still many people that stop taking this medication for various reasons.

Metformin puts little, if any, strain on many of the internal organs, is not associated with weight gain, and is also one of the most affordable diabetes medications available on the market.

The main side effects noted negatively impact the gastrointestinal tract. Although these minor side effects can deter individuals from taking this medication.

Possible Side Effects

Some of the most common side effects that can occur with metformin use include:

  • Diarrhea
  • Bloating
  • Stomach pain
  • Gas
  • Indigestion
  • Constipation

Possible Serious Side Effects

This drug has a black box warning, which is the most serious warning that the Food and Drug Administration issues regarding medications. This warning alerts patients about potential drug effects that may be dangerous and cause serious harm.

The main serious side effect that can be seen with metformin use is lactic acidosis.

Lactic acidosis occurs when lactic acid builds up in the bloodstream. Lactic acid is a byproduct of energy production in cases where oxygen levels are low.

When metformin is broken down within the body, this medication inhibits gluconeogenesis in the liver to prevent extra glucose from being manufactured. As part of this step, an enzyme known as pyruvate carboxylase is inhibited, and this results in the buildup of lactic acid in the bloodstream. Metformin can also inhibit the breakdown of lactic acid, further increasing levels within the blood. When left untreated, lactic acidosis can cause confusion, liver failure, trouble breathing, weakness, cramping, rapid heart rate, and even death.


The FDA has issues a number of warnings regarding metformin use as well:

  • Do not take metformin with alcohol. Alcohol can increase your risk of lactic acidosis from metformin by inhibiting your liver function. Alcohol may also raise or lower your blood sugar levels due to its high sugar content and poor nutritional value.
  • Do not take metformin if you have moderate to severe kidney injury or disease. Metformin inhibits kidney function and can lead to multiple organ system failure if left untreated. Kidney dysfunction can also increase your risk for having lactic acidosis.
  • Do not take metformin if you have liver problems. Liver disease is a risk factor for lactic acidosis, and metformin inhibits liver function and may cause liver failure.

The dosage of metformin you will be prescribed is affected by the type and severity of the condition you are using metformin to treat. Your age, the form of the medication you are taking, and any other existing health conditions you have been diagnosed with all play a role in your dosage. It will also depend on what you are taking Metformin for; diabetes, or anti-aging purposes.

In many cases, your provider will start you off with a low initial dose of metformin. This dosage can then be altered and adjusted over time to ensure the proper benefits are being provided. It is common practice to use the lowest possible dosage to elicit the desired effects. Elderly patients are often prescribed lower doses as well as kidney function is often inhibited. This can lead to reduced medication clearance and elevated or toxic levels in the blood.

There are two different forms of metformin that you may be prescribed: regular and extended release. The extended release version is often tolerated better by many individuals, because the effects are distributed over the course of several hours. However, some people may require the regular dose if they have especially high levels of glucose after a meal.

Metformin is the generic form of this drug. There is also a brand name version of this medication, with the immediate-release form called Glucophage. The extended-release forms are Glucophage XR, Fortamet, and Glumetza.


The immediate-release form comes in dosages of 500 milligrams, 850 milligrams, and 1,000 milligrams. Each of these is taken orally in pill form. The extended-release tablets are supplied in dosages of 500 milligrams, 750 milligrams, and 1,000 milligrams.

For adults, the most common starting dosage for is either 500 milligrams twice a day or 850 milligrams once per day taken with meals. This dosage can be increased up to 2,550 milligrams per day, and any dosages over 2,000 milligrams must be split into three doses each day.


Extended-release medications often begin with a 500-milligram dose once in the evening. This dosage can be increased to up to 2,000 milligrams daily taken in two doses.

For children between 10 and 17, only immediate-release tablets are used for the majority of patients. The typical starting dose is 500 milligrams taken twice per day, with the maximum dosage being 2,000 milligrams per day. This medication has not been studied in children under 10 years of age and should not be used by them until further research has been conducted.

Always Talk to Your Doctor

Metformin is not an over-the-counter medication, and because of this, it must be prescribed by a doctor.

If you feel that metformin may be a good option for you, it is important to speak with your physician as they will help you find out if this medication will be right for you.

This medication can react with other medications and cause serious side effects and health issues. Because of this, your doctor will be able to speak with you and evaluate your current health status, prescription and over-the-counter medications, and potential future health diagnoses. This will allow you to better understand the potential benefits of metformin, and if they are relevant to your specific situation.


The benefits of metformin relating to type 2 diabetes management are well known. The various other potential uses for this medication are becoming more established through various trials. Metformin for anti-aging has becoming increasingly popular.

The current research suggests that metformin can provide a number of benefits including;

  • Reduced incidence of cancer and heart disease
  • Decreased inflammation
  • Slowed cognitive decline and dementia progression
  • Improved cellular communication and repair

While further studies may still be needed to confirm results, establish proper dosages, and ensure safety, there is most definitely potential for this medication to be used to slow the aging process. The TAME Trial that is currently taking place should provide significant evidence of the potential benefits of this medication. In the coming years, metformin may become more widely available and used to slow the aging process and increase longevity.

About six months before I turned 50, a friend tried to convince me to enter a physique contest. He had just turned 40, and was thrilled to be in the over-40 category because there were fewer guys for him to compete against. He said to me, “Kirk, you can win the over-50 category. There are only a few guys who enter. But, you have no lats or traps—most older dudes don’t. Work on your back and you got it in the bag ! ” I wasn’t too excited to enter a competition with “no competition, ” but I was pretty peeved to hear him say I had no lats or traps. My back was better than that. Although I had no volonté to enter the competition, I started doing more single-arm dumbbell rows to work my back. Now, a few years later, it’s one of my favorite dumbbell exercises. Importantly, I’m not trying to break any records when it comes to weight here, like I might have in my younger days. Quality reps at low weight is the bigger focus.

There are versions of the exercise where you see guys use a bench for support, using a hand or even placing a knee on the bench. These have their merits ( although MH sport director Ebenezer Samuel, C. S. C. S. would rather you not put a knee up ). However, I mostly do the version with no assistance from the bench with both feet on the ground as points of contact. This version works your traps, rhomboids, rear delts and rotator cuff groupes de muscles, but you also get some core work, something you greatly need as you get older. Remember, though, that the way do the exercise is subjective to your own abilities. If you need some extra support for balance, don’t hesitate to put a hand down.

tera set up for my preferred variation, pick up a light dumbbell, especially to start. Stand with your feet in a parallel stance about shoulder-width apart. Hold the dumbbell in a neutral place at your side, as if you would for a hammer curl. Place your free hand behind you, with the back of your hand on the small of your back ( you can also extend your off arm out to balance ). Next, bend over by pushing your butt back and hinging at your waist, with your knees slightly bent. There should be no rounding of the spine, and you should keep your gaze down at the floor in a neutral neck position. Lastly, as you’re hanging onto the dumbbell with your arm pointing to the floor, squeeze your shoulder blades together so your shoulders lock in place and don’t slump.

From this starting position, use your back to sweat the dumbbell up without twisting your spine. Pull up as high as you can, pause for a moment at the top and squeeze your shoulder blades together even more. Then release by lowering the dumbbell back to the starting place. tera control my pace, I usually pull up for 2 seconds, squeeze at the top for 2 seconds, then release back to the starting place in 2 seconds.

By doing the dumbbell row unilaterally ( one arm at a time ), you’ll feel yourself being pulled off balance. You must fight with your abs and obliques to maintain balance and stability, which is why I love this exercise so much. Although you won’t be able to load up with as much weight as you would using the bench for stabilization, the extra core work you’ll get makes this version well worth putting in your arsenal of exercises. Try 4 sets of 8 to 10 reps during upper body workouts to get started.

We all know that it’s common for men to skip the doctor until they become sick, injure themselves or are faced with a serious health problem. And a majority of men will postpone seeking care for a few days to see whether they feel any better. It’s the whole ' if it ain’t broke, don’t fix it ' line of thinking.

But there are steps the men in your life can take today to improve their vitality and help prevent health problems down the road. Of course, there are some things that can’t be changed, such as family history and age, but every day choices can have a big impact on their current and future health.

Eating a diet that’s low in fat ( less than 7 percent of calories should come from saturated fats ), cholesterol, and salt, and packed with fresh fruits and vegetables ( two cups of fruit per day; three cups of vegetables per day for men up to age 50 and two and a half cups for men aged 51 and over ), whole céréales and fiber can help improve your health, prevent heart disease, diabetes and certain cancers.

Try to get 30 minutes of moderate physical activity on most days of the week. Taking a walk, jogging, swimming and mowing the lawn all count. But don’t be a weekend sports warrior. Start slowly if you aren’t normally réactive and gradually build up. No time ? Research shows that even short bursts of physical activity—as few as 10 minutes of soutenu activity several times a day—can help men improve their health. Talk to your doctor about the right exercise program for you.

It’s important to maintain a saine weight. Excess weight, especially around the waist, can be on your body. Carrying too much body fat forces your heart to work harder and increases your chances of heart disease and stroke, even if you have no other risk factors ! So, try to curb weight gain as you age.

Tobacco smoke contains more than 4, 000 chemicals and is a known cause of cancer. Smoking also increases the likelihood of high blood pressure, heart disease, lung problems and other health problems. And if you think chewing tobacco is safer, think again. Not only is chewing tobacco a known cause of cancer ( carcinogen ), it also contributes to gum disease and tooth loss and may be linked to fertility problems. And, few could argue that chewing and spitting is attractive to a partner. If you smoke or chew, talk to your health care professional about ways to quit. Consider nicotine replacement therapy products that include self-help programs, if appropriate.

Whether it’s pulling out the weed whacker, going for a bike ride or grilling with the neighbors, safety is key. Here are just a few examples : Take care when moving heavy objects. It’s easy to strain yourself when lifting boxes, furniture and other heavy items. Use your knees and legs and not your back for leverage. And ask for help, if you need it. Wear appropriate protective gear for your eyes and ears when using leaf blowers, lawn mowers and other machines at home or work. Excessive exposure to noise is the most common cause of hearing loss. Wear a helmet when you ride a bike or ski and throw on reflective clothing if you go for a run after dark. When grilling, never leave the grill unattended, especially when small children and pets are around, and keep a fire extinguisher handy. The grill should be at least 10 feet from your house or any building. tera protect your skin, avoid prolonged exposure to the sun and apply ( and reapply ) sunscreen with an SPF of 15 or greater that provides protection against UVA and UVB rays.
