Vitamins Men In Their 40s Should Take For Overall Health Optimization


Congratulations, you’re now in your 40s! In a few short years, you’ll be celebrating your Golden Jubilee. You may have noticed that your body isn’t what it used to be, and now you’re wondering what you should do. Whether you should start supplementing. Which vitamins are best…

Well, let’s discover how to turn back the clock a bit, and get you feeling like you just graduated high school! We’ve also covered a similar post for men in their 20s, men in their 30s, and men in their 50s, respectively.

Vitamins play a major role in keeping you healthy. The older you get, the more important they become. Vitamin supplements are one of the best ways to make sure you meet your daily required intake. The best vitamin supplements for 40+ year olds, are vitamins A, B, D & E.


As you’ll soon find out, these are more than just random letters. In severe cases, these letters could even be the difference between life and death.

The Magic of These Four ’40s’ Vitamins

These vitamin supplements exist so that you can live your best life possible, without interference from ailments that come with aging. They allow your body to keep firing on all cylinders! Like we’ve said, whether you’re in your 30s or even in your 50s, taking the right vitamins quietly works wonders for your body.

A Is For Anti-Aging

The effects of not having enough Vitamin A in your body is very dire. Reduced levels of Vitamin A rob you of your natural night vision. It could cause Age-Related Macular Degeneration (ARMD), which means you lose your central vision as you age. In extreme cases, you could even potentially go blind.

Vitamin supplements are a great way to build up your vitamin A levels. Having adequate levels of this vitamin could give you;

  • Increased immunity
  • Stellar day & night vision
  • Improved sexual reproduction capabilities
  • Improved respiratory system
  • Optimal heart function
  • Greater organ function

Now, you know why you need to have vitamin A in your body during this important decade of building upon your previous successes and foundations.

The good news is that vitamin A is super easy to obtain.

Several food and fruits contain it. The only caution is that, in your 40s, you may not want to eat too much vitamin-A-rich food to overreach the required daily amount (900 mcg RAE). This daily requirement tends to ratchet up the more you age.

Taking vitamin A supplements saves you the hassle of scouring for foods rich in it. Plus, you’ll get to reach your daily consumption requirement much faster and easier.

Note – this does not mean you should go crazy on vitamin supplements as, like many good things in life, too much can be harmful.

Vitamin B Brought Its Best Bros

Vitamin B is here and it brought its (many) brothers out!

This vitamin gives you the best of the best to help your body’s optimized functioning.

Vitamin B can be further classified into:

  • B1 (thiamin)
  • B2 (riboflavin)
  • B3 (Niacin)
  • B5 (pantothenic acid)
  • B6 (pyridoxine)
  • B7 (biotin)
  • B9 (folate)
  • B12 (Cyanocobalamin)

You can, of course, obtain this vitamin exclusively by eating foods rich in itHere are some notable B’s to consider at 40+:

Vitamin B12 Thiamin


Vitamin B12 is crucial to remaining (or becoming!) a fit and healthy man, especially as you grow older. The downside to this vitamin is that it doesn’t stay too long in your body, meaning you need to maintain a steady intake of it.

If you are a vegetarian or vegan, getting vitamin supplements may be the wisest choice for you since vitamin B12 is found mainly in animal products. B12 is a constant struggle for vegans to get in adequate amounts, which is where blood-testing comes in handy.

B12 assists you in DNA synthesis, production of red blood cells, releasing stored energy from food, and folate production.

Although you can safely consume a lot of this vitamin (because you excrete any excess), it doesn’t hurt to be cautious.

Vitamin B6 Pyridoxine

Vitamin B6 performs a whole host of functions…

It helps combat depression, moodiness, and anxiety. If you want to gain more emotional control over yourself, this could be a start to using your focus properly.

It also produces hemoglobin, which helps prevent and treat anemia. B6 also can help clear out blocked arteries, and even reduce the possibility of heart disease.

Vitamin B9 Folate

This vitamin is essential when it comes to the creation of red blood cells.

Also, it directs the cells in their daily functions (of which there are many).

Folate promotes the development of healthy tissue and stimulates appetite. If you prefer not to wolf down the right food sources containing B9, you can always take vitamin supplements.

Vitamin D

This vitamin is absolutely necessary, as we’ve stated before.

The older you become, the more you rely on vitamin D. And likely, if you’ve got bad sun-soakin’ habits, this will just remain harder to fulfill with age.

This vitamin helps maintain the amount of calcium and phosphate in the body, which improves bone strength – doubly important as a still-active man ages.

Apart from bone growth, vit-D helps boost your immune system, and increase your brain’s memory capacity.

It could also improve your mood, lung capacity, and contribute to cardiovascular health. More importantly, it helps destroy the genes involved in cancer cell growth.

Vitamin E

Studies show that after 30, it becomes more important than ever to prioritize healthy skin production.

This is because your skin reduces the amount of collagen it produces, which ultimately could lead to the reduction of your skin’s quality… IF you don’t supplement.

Sagging and wrinkles may start to become more prominent on your skin. This gets worse (and faster) in your 40s, unless you can maintain as high a level of vitamin E as possible.

Giving you the best skin and slowing your aging process are not the only things Vitamin E has to offer you, man of 40 plus…

It also helps remove chronic metabolic waste, which can harm your body in the long run. Think of it as aiding in detoxifying and purifying your body on a cellular level.

How These Vitamin Supplements Work Together (Combined Effects)

If we just revealed some never-before-understood benefits to you… Strap in your seat, because we’re going to turn up the volume.

The magic of this collection of vitamins, taken in your 40s, is that together they are far more powerful! They create a “Gestalt” effect, wherein the whole is much more beneficial than just the sum of its parts.

Vitamin A, B & D: The Prostate Protectors

Vitamin D boosts testosterone levels, as we’ve said. And your testosterone levels slowly decrease when you hit your 30s…

So if you want to keep riding at the rodeo, you just need to maintain a safe level of vitamin D in your system during this decade.

Vitamin A supplements work well in tandem vitamin D supplements.

This vitamin helps boost your libido, while also reducing the risk of prostate cancer. Vitamin B12 blends with these other two vitamins (A & D) as it aids in the production of sperm.

This means you can remain in active service in your 40s and beyond, so…

At ease, soldier. Or, are you the general in this metaphor? We’re not sure.

Vitamin B6, B9, B12 & D: The Heralds of Good Mood & Energy


As you may or may not know, vitamin B6 helps combat moodiness, depression, and anxiety. All traits that hinder your social experiences, more than they help.

And while vitamin D plays a core part in brain development… having a low amount of vitamin D in the body has been linked with early signs of depression.

Thus, vitamin D and the applicable B vitamins are crucial to giving you the best mental health at this age.

As for energy, the mentioned vitamins perform a combined function while breaking down fuel. Vitamin D protects mitochondria, and improves their ability to generate energy.

Vitamins B & D On Strength-Building

The almighty vitamin B12 helps oxygenate your muscles, and facilitates red blood cell production. This comes in supremely handy when staying fit at any age.

These cells then transport oxygen to your muscles.

Vitamin B6 in turn ensures your muscles are rejuvenated and repaired after each workout. The muscles which have been built are then supported by the strong bone structure provided by vitamin D.

In addition, vitamin D promotes the absorption of other nutrients, which boosts the absorption of protein. This then influences the growth and repair of your strength and muscles.

Vitamin B & D On Sleep

Research shows that vitamin B can contribute to an enjoyable sleep.

It helps manage the amount of tryptophan (an amino acid in the body) that assists melatonin production, which is responsible for sleep. This chain reaction can in turn regulate your adenosine levels for the most optimal sleep!

Be aware that vitamin D deficiencies also can cause a lack of, or restful sleep.

Vitamin B6, B9, B12 & E… And Your 40-Year Old Noodle

You might’ve noticed at times, your brain may not be as sharp as it once was. Left unchecked, it may continue to worsen as you grow olderstructurally and cognitively.

However, vitamins B6, B12, B9, and E are important for continual brain development and activity as you continue to age gracefully.

Vitamin E has been proven to contribute to the protection of the brain, by expunging free radicals that can damage the brain cells of the body.

Vitamin D & Getting Lean & Mean

52.4% of middle-aged men are concerned with trying to lose weight. Did we say middle aged? Sorry, we meant “seasoned men in their 40s”.

We’ll save “middle-aged” for our 50s decade vitamin post. Better?

Vitamin D is your go-to guy for this fix. Strong evidence points to vitamin D supplements helping with fat and overall weight loss as it’s known to reduce appetite. Plus, for overweight guys, this supplement even reduces the risk of having potential heart diseases.

The Average ’40-Something’ Guy’s

Supplement & Vitamin Intake Needs

Vitamins (and the strong combination of them!) are vital to how efficiently your body works…

From the way your nerves operate, to how active you can push yourself to be, to how positive or drained you feel, they’re involved in everything.

They’re the building blocks of YOU. Your body simply wouldn’t work properly, without receiving the right vitamins, in the right amounts.

As a 40+ year old man, staying on point with nutrition, exercise, sleep, and stress is now a non-negotiable.

However, don’t get overzealous when taking these vitamin supplements, as they may cause harm to your body. Take them in a balanced way, and try to seek out the optimal balance and blend of vitamins that you may be deficient in.
