Best Supplements for Men Over 40: Strength, Bodybuilding, & General Health

When searching online about age-related changes to the body, there’s a lot of information available about women. But what should men consider when they begin to go through the aging process? What happens to the average male body after 40? As men age, the skin becomes less pliable and less able to restore itself when damaged. This means that wrinkles become more pronounced. Hair begins to show up in strange places, and the body experiences more aches and pains. Many men might also suffer from reduced muscle mass after 40. This can have significant implications for men who want to maintain active lifestyles that include strength training and even bodybuilding. However, with the right diet, exercise routine, and supplements, men over 40 can continue to feel good and maintain good health even as they get older with time.

Why Changes Happen to Men After They Turn 40?

There are a number of factors that cause changes in mens’ bodies after the age of 40. A decreased protein intake is one common culprit behind these changes. Testosterone levels also cause some of these changes, considering that they begin to drop by around 1% each year. As a man, once you celebrate your 40th birthday, your body will experience a decrease in growth hormones and be less able to remove energy from protein.

Specific supplements are designed to help men over 40 undergo the aging process without some of the common issues associated with it. As a man over 40, you can even reach your strength and bodybuilding goals and maintain the weight that you want by taking the right supplements. Some of the most important supplements designed for men over 40 work to restore your body’s testosterone levels. The right combination can also improve your general health. As the body ages, there are several important vitamins and minerals that it needs. When you take these supplements, you can make sure that your body is getting the proper support that it needs. Here are the best supplements for men over 40.

Which Supplements Are Best For Men Over 40?

When researching what supplements are right for you, it’s important to consult with your doctor first. Some supplements can be dangerous when taken at dosages that are too high.

Vitamin B12

Vitamin B12 is one of the best supplements for men over 40 because it is vital for brain health. It also helps your blood function normally. When you lack B12, your muscles may feel weak, a condition that makes exercises such as bodybuilding especially challenging. You may also suffer from shortness of breath, heart palpitations, and overall fatigue. You might even feel dizzy or have memory problems if your body is missing too much vitamin B12.

The human body is unable to make B12, so it is something that you must get from your diet. Men need about 2.4 micrograms of vitamin B12 each day. The body takes the amount that it needs and eliminates the rest, so it’s important to replace the vitamin every day. When you get enough B12, your body will metabolize proteins and fats more easily. It will also help your body turn carbs into sugar for energy.

If you eat meat, then you could already be ingesting enough B12. The vitamin is naturally in meats like pork, beef, fish, seafood, poultry, and eggs. If you are vegetarian or vegan, then make sure that you’re eating soy products or fortified plant milk. To make things easy on yourself, take a B12 supplement to make sure that you’re getting your daily dosage.


Potassium is a needed supplement for men over 40 because it works to keep the body’s blood pressure levels healthy. High blood pressure is often the first sign of other age-related illnesses. Potassium is also good for your kidneys, and it will help many of your other organs work properly.

Red Blood Cells

You can get potassium from foods like avocados, nuts, leafy veggies, and milk. However, when it comes to getting it by taking supplements, potassium is one of the easiest supplements to take because it is available in liquid or capsule form. The supplement helps regulate fluids as well as balance the minerals that move in and out of your body’s cells.

Potassium also aids nerve impulses, and if you’re into intense forms of exercise such as strength training or bodybuilding, you’ll appreciate that potassium helps your muscles contract. How much potassium should you get? For most adults, the proper amount of potassium is 4,700 milligrams a day.


Most people know that calcium builds strong bones, but did you know that it’s also critical for post-workout recovery? If there isn’t enough calcium in your diet your muscles won’t be able to properly relax. When your muscles can’t relax properly it results in less potential energy when it’s time to work out. Less energy results in reduced strength and a decline in performance, making your workout not as effective as it could have been. For most people that are bodybuilding or training, drinking plenty of milk can help achieve the recommended levels of calcium (most bodybuilders would tell you 2000-2500 a day is enough). One cup of 1% milk contains roughly 305 mg of calcium; If you don’t think you can stomach 6-8 cups of milk per day, there are several supplements on the market that contain the calcium you need. 


Taking iron supplements is something that you must check with your doctor first before taking. Before you take iron supplements, you need to be sure that you are iron deficient. If your body intakes too much iron, it can lead to nausea, vomiting, stomach pain, and diarrhea. Over time, iron can accumulate within the organs which can be fatal. 

Given that information, if you are iron deficient then taking iron supplements can benefit muscle growth considerably. Iron deficiency usually results in lowered energy levels, so those that are iron deficient can expect to feel more energetic after supplementing. Additionally, iron forms hemoglobin. Hemoglobin is the pigment that’s responsible for transporting oxygen from the lungs to your muscles. Regardless of if you’re a bodybuilder or not, iron is one of the most important supplements you should ask your doctor about when you’re over 40 to ensure you’re not deficient. 

Vitamin D 

Also known as the sunshine vitamin, vitamin D helps maintain strong bones, similar to calcium. Recent studies have suggested that vitamin D may also play a role in muscle function and growth. Vitamin D deficiency is common among people from all walks of life, and athletes are not an exception. Being deficient in Vitamin D leads to things like muscle weakness and atrophy. Consider supplementing vitamin D after discussing with your doctor if your levels are correct or not. 

Vitamin K

One of the most necessary supplements for men over 40 is vitamin K. You can take a capsule version of it to get it or you can make sure that you’re including leafy greens, eggs, and broccoli in your diet. Vitamin K helps the body develop and maintain strong bones. It is also good for your cardiovascular health. One of the key functions of vitamin K is making sure that calcium is sent to the places in your body that need it like your bones and teeth.

You might be lacking vitamin K if your body doesn’t absorb nutrition well or if you don’t tend to include veggies or dairy in your diet. Men need an estimated 120 micrograms of vitamin K daily and this dose becomes increasingly more important as they age. While most people get enough vitamin K from their diet, if you are low in it, you could experience issues with limited mobility. Getting enough will help keep you moving, and it can help you reach your bodybuilding goals if that’s something you’re interested in.

According to research, older adults with decreased amounts of vitamin K are an estimated 1.5 times more likely to experience decreased mobility. They are also more likely to develop a disability involving mobility when compared to people who have the proper amount of vitamin K.


Creatine is a controversial supplement that is often misunderstood. For years there was a misconception that creatine was a performance-enhancing drug. With modern advancements in supplement research, we now know that creatine is found naturally in the body. Today, creatine is hailed as an anaerobic energy booster, that can boost the energy of people immediately. It’s also believed to have the power to improve muscle strength and be a direct source of energy for high-intensity interval training. In situations like high-intensity interval training, our body produces very small amounts of creatine and draws power and energy from the amino acid. For those that are serious about training and building muscle, creatine is a great option. If you’re more concerned about taking supplements for general health, then creatine is one you can likely overlook.


One of the top supplements for men over 40 is zinc. The substance is essential for your body’s immune support as well as for your overall metabolic function. Your body relies on zinc heavily. In fact, only iron has more mineral concentration throughout the human body. Zinc helps with more than 300 enzyme reactions that happen in your body daily.

When you have enough zinc, you’ll enjoy good cognitive function. It helps your body manage oxidative stress and maintain your testosterone levels. The proper amount of zinc can help you avoid prostate problems. The substance can even keep your hair strong and healthy, making it one of the best supplements for men over 40.

IGF-1 From Deer Antler Velvet

Natural IGF-1 is one of the most effective supplements on the market that men over 40 can benefit from. It is a multi-purpose supplement that allows men to train harder, accelerate their recovery time and build more lean muscle. It can also help individuals lose weight and boost their energy levels. Growth factors in Deer Antler Velvet Spray can help you maintain a healthy weight no matter your current diet or weight loss plan.

Man Over 40 Strength Training

Whenever you exercise, you are basically tearing apart muscle fibers. Your muscle fibers will then reconstruct themselves, which causes muscle mass to increase. This process makes the cells in your muscles bigger. When you take a supplement that includes growth factors, like Deer Antler Velvet Spray, your muscles can undergo this growth more easily.

If you’re into bodybuilding, then you probably plan your workouts to target certain muscles. Be sure to include Deer Antler Velvet Spray in your list of supplements because it works to boost the cells in the muscles that you’re focusing your workouts on.

Deer Antler Velvet Spray is also one of the top supplements for men over 40 because it increases energy levels. When humans are children and young adults, their bodies naturally produce elements that provide energy, but once people hit 25 years old, bodies produce fewer of these elements. A supplement can return one’s energy levels to the point that they were at when they were younger.

Aging also makes men more prone to injury when you participate in intense physical training. If you’re working hard to reach your fitness goals, the last thing that you want to happen is an injury that delays your progress. Excessive sore muscles due to intense workouts are also frustrating. Taking a supplement with a growth factor, like Deer Antler Velvet Spray, can decrease recovery time and minimize muscle soreness faster.

The human body produces a protein called IGF-1 that helps cells develop and recover. As the human body ages, it produces less of this protein. The decrease makes the signs of aging more noticeable. It is also why recovery takes longer. Deer Antler Spray supplements like those produced by Nutronics Labs include IGF-1 in them, making our products one of the best supplements for men over 40. For more information, check out our wide selection of products with combinations of both IGF-1 and Deer Antler Velvet Spray.
