Starting our list off, our top pick for the best aging men’s multivitamin is Kirkland Signature’s Adults 50+ Mature option. Not only does this have solid formulas of all its vitamins, as well as third-party certification, it’s also third-party certified. Let’s take a closer look. 

While this supplement doesn’t have as many megadosed vitamins and minerals as some of the other vitamins later on our list, this is likely ideal for maximum effectiveness as we’ll cover later on. Most of the micronutrients are dosed right around the 100% mark, giving you an ideal amount to supplement your diet. Vitamin B12 is the one “megadosed” ingredient with 1042% of your DV. 

This product is USP (United States Pharmacopeia) Verified, ensuring it’s met a set of strict testing criteria. It’s also worth noting that this isn’t a vegan supplement as it does contain gelatin in its formula. 

Finally, as you may expect with 400 servings per container, this is a great budget option if you’re looking to buy a multivitamin in bulk. It’s one of the most budget-friendly options on our list at only ~$0.05 per serving.

Taking the runner-up spot on our list is Nature’s Way Alive, which is another men’s 50+ multivitamin. Although this is more expensive than Kirkland’s option, it may be a good pick if you want additional proprietary blends in your supplement!

This supplement has significantly higher doses of most of its vitamins and minerals when compared to Kirkland. While this is likely unnecessary, it may be beneficial if you want high amounts of things like Vitamin D, Zinc, B Vitamins, and more. Many of the micronutrients have high doses of 200%+ of your DV.

This is also the first supplement we’re covering that contains several proprietary blends including enzymes for digestive support, a “mind and body energy blend”, a greens blend, and more! Keep in mind that blends may not be ideal for certain ingredients as it’s often impossible to tell how ingredients are dosed. 

Like all Nature’s Way products, you can also expect a high level of manufacturing quality. This supplement is GMP-certified, NSF-certified, and more, ensuring exceptional quality. However, similar to Kirkland’s product, it does contain gelatin so it isn’t suitable for vegans or vegetarians. 

It’s worth noting that this isn’t available in the same large package size as Kirkland, only coming in a 60-serving bottle. As a result, it’s significantly more expensive at ~$0.34 per serving.

Taking the third spot on our list is Sentry Senior from 21st Century, which is another option that comes in a budget-friendly bulk package. Let’s see how it compares to the first 2 picks on our list. 

In terms of dosages, it’s more similar to Kirkland, with most of the vitamins and minerals falling around 100% of your DV. This makes it a good choice if you’re looking for a more basic supplement, without any unnecessarily high doses. 

Like the top 2 products on our list, 21st Century has solid third-party certification, assuring their multivitamin is “Quality Laboratory Tested.” Also like the top 2 products on our list, there’s gelatin in the formula, making this unsuitable for vegans. It’s also worth noting that low amounts of artificial dyes are included in the formula if you prefer to avoid these ingredients. 

As you may expect based on the large package size, this is another budget-friendly option. It’s tied with Kirkland for the cheapest option on our list at only ~$0.05 per serving.

Next up on our list is GNC’s Mega Men Multivitamin, which is our pick if you’re looking for a supplement with additional antioxidants. Let’s take a closer look!

First, you can expect very high doses of most of the ingredients here similar to Nature’s Way. While this is likely unnecessary, you are ensuring strong amounts of things like Vitamin D, B Vitamins, and Zinc. 

As mentioned, this is a great pick if you want antioxidants in your supplement as GNC’s product contains 28.96mg of an antioxidant blend, as well as 62.5mg of Fruits and Veggies. 

Although it doesn’t appear GNC uses third-party testing, they do ensure quality with their own in-house testing and standards. Also, this is the first product on our list that doesn’t contain any gelatin, making it the first vegan-friendly option on our list. 

Finally, like Nature’s Way, GNC only comes in a relatively small package size of 90 servings per container. As a result, it’s somewhat expensive at ~$0.34 per serving.

Next on our list is Life Extension’s multivitamin, which is very heavy in megadosed ingredients. Let’s see what you can expect!

Most of the vitamins and minerals here are dosed very high, with many of them having over 1000% of your DV. As a result, you could very well take a half-dose of this supplement and still get high doses of all the micronutrients here!

Like GNC, there’s no explicit third-party testing, although Life Extension promises purity, potency, and quality in all their formulas. Also, as this product doesn’t contain any gelatin, it’s completely vegan-friendly.

Finally, similar to GNC and Nature’s Way, Life Extension comes in a relatively small package size, meaning it’s quite expensive compared to bulk supplements at ~$0.32 per serving. However, you could save some money by only taking 1 capsule a day instead of 2!

Next up on our list is Ora Organic Modern Multi. This is the first product on our list to contain iron, which may be of special interest to vegans in particular! Beyond this, let’s see what you can expect from Ora’s product. 

This is one of the most moderate supplements on our list, containing relatively low doses of most of its vitamins and minerals. While there are a few that have doses of 100%+, most fall around the 25-50% mark. However, this may be ideal as you’ll be getting more effective doses compared to megadoses. As mentioned, this is also the first supplement to contain any iron with 35% of your DV. 

Ora proudly displays their testing certifications with an entire section on their website dedicated to their Certificate of Analysis. Also, like all of Ora’s products, this multivitamin is also proudly 100% vegan. 

Although this is an undeniably high-quality product, it comes at a fairly steep price. On top of only coming in a 30-serving bottle, each serving will cost you about $0.75, making this the most expensive supplement on our list so far.

Next on our list, we have another multivitamin from an all-vegan company, Future Kind. This is a great option if you’re looking for a vegan supplement with additional probiotic support, just be aware that it’s fairly expensive. 

In terms of doses, Future Kind contains many high doses of its vitamins that are well over 100% of your DV. However, some vitamins are dosed quite low, making this a relatively unbalanced supplement. While you could take a lower dose of 1-2 tablets, you would be getting a very low dose of certain vitamins and minerals.

In terms of additional ingredients, Future Kind may be a good choice as each serving contains 75mg of an Enzyme complex. In addition to this, you can expect 315mg of a Fruit and Vegetable Proprietary blend. 

On Future Kind’s website, you can find rigorous third-party testing results for contaminants like heavy metals. Also, as this is a vegan company, this product is 100% vegan-friendly. 

Finally, this is the most expensive supplement on our list so far at ~$1.00 per serving, which is 20x as much as the cheapest options we’ve featured!

Closing off our list is Transparent Labs’ Multivitamin which is the first supplement on our list to contain Ashwagandha. This ingredient may be of interest for its recovery enhancing and testosterone-boosting properties!

Transparent Labs contains solid doses of most of its ingredients, with all of its vitamins coming in doses of 100%+ of your DV. This means you could easily split it into multiple smaller servings if you want a more moderate supplement. 

As mentioned this is the only supplement on our list to contain ashwagandha at a moderate but effective dose of 300mg per serving. Ashwagandha has been shown to boost testosterone levels, so it may be of special interest to men over 40, but it also shows significant effects on stress management and sleep quality! It’s worth noting that if you split this supplement into multiple doses, you may not get an effective dose of Ashwagandha in each serving.

Keep in mind that there aren’t any longterm studies on the effects of daily ashwagandha use, so it may not be ideal in a daily multivitamin. If you’re interested in Ashwagandha, we recommend taking on its own instead so you can better control your intake. 

Transparent Labs multivitamin is also Informed Choice certified, ensuring a high-quality, well-tested supplement. It also contains no animal products, making it completely vegan-friendly.

Finally, this is tied with Future Kind’s supplement for the most expensive product on our list at ~$1.00 per serving. Keep this in mind if you’re trying to prioritize value for money with your decision!

In What Situations Do We Need Multivitamin Supplementation?

If you’re eating a nutritionally complete diet, you likely don’t necessarily need a multivitamin supplement. However, there’s a good likelihood you could benefit from one! Below we’ll be covering a few scenarios where a multivitamin may be beneficial!

1. During Periods of Caloric Restriction

If you’re looking to lose weight, you’ll need to be eating in a caloric deficit. As a result, it can be tough to get all the necessary nutrients while still eating a relatively low-calorie diet. While we recommend eating lots of nutrient-dense whole foods on a diet, it can still be difficult to know if you’re getting enough nutrients.

As a result, a multivitamin can help you meet all your daily nutritional goals without any additional calories.

2. Food Intolerances and Restrictions

Similarly, if you’re vegan, vegetarian, or have any other dietary restrictions or intolerances, it can be difficult to get certain nutrients through food alone. The main nutrients of concern for vegans specifically are Vitamin B12, Iron, Calcium, and Vitamin D.

As a result, a high-quality multivitamin can help fill in any gaps in your diet that are caused by not eating certain foods for whatever reason. 

Whether you’re vegan, or have any other dietary restriction, it’s a good idea to get some blood work done as it’s more than likely you’re deficient in one or more key nutrients!

3. Older Age

Multivitamins appear to be especially beneficial for protecting cognitive health in older adults. Recent studies have shown that older adults taking multivitamins perform better on tests related to cognitive decline compared to those taking a placebo.

Alongside general effects on overall health, these findings should encourage most older people to start taking a multivitamin!

At the same time we have another long term randomized human study that shows no effects. This can be somehow explained by a very possible trend - people who are more concerned about their vitamin and mineral intake also tend to have better habits. This highlights how important nutrition and physical activity is at any age!

4. Malabsorption Conditions

Finally, people with conditions that affect digestion (celiac, cystic fibrosis, etc.) may benefit from the use of a multivitamin. This is because their bodies likely have difficulty absorbing one or more key nutrients. Multivitamins are a good way to increase total intake which will lead to better absorption by the body. 

Similar to the point above about other dietary restrictions, get your bloodwork done to see if there are any specific nutrients you’re deficient in, and decide on which multivitamin is right for you from there.

How to Choose the Best Multivitamin for Men Over 40?

If you’re a man over 40 looking to take a multivitamin, there are a few key factors you’ll want to look out for. These include the doses of each vitamin/mineral, as well as third-party certifications. We’ll be covering these in more depth below!

1. Choose a Supplement Without Megadoses of Vitamins and Minerals

First, consider the doses of each vitamin and mineral included in each serving. Many multivitamins will include “megadoses” that contain well over 1000% of the RDV of a vitamin. While this may look impressive, it’s unlikely taking in such excessive amounts of any vitamin is more beneficial than taking in a moderate dose.

It can be justified in some conditions where bioavailability is poor, but not in every case. Keep in mind that very high doses of some vitamins and minerals can be harmful instead of beneficial. 

Many supplement companies will use this as justification for a higher price tag, so we recommend sticking with products that have more moderate doses. If you do choose a supplement with many megadosed ingredients, it can be a good idea to take smaller serving sizes to get more value for your money.

2. Choose a Supplement With a USP Label or Certification From Another Recognized Organization

As with all supplements, it’s always a good idea to check for some level of third-party testing and certification. This can be from organizations like USP, GMP, Informed Choice, or other recognized organizations. 

Several of the companies on our list don’t include third-party certifications, instead ensuring their own in-house quality standards. While this isn’t as ideal as third-party certification, companies with solid reputations for quality can usually be trusted.

If a brand doesn’t contain any third-party certifications, we recommend checking their website to see their policy on quality assurance.

3. Choose an Iron-Free or Low-Iron Product

Finally, unless you’re iron deficient, you may want to choose a supplement that doesn’t contain any additional iron in its formula. Taking a supplement high in iron when you already get enough through your diet may lead to iron toxicity. Symptoms include constipation, nausea, and abdominal pain. 

Consider getting blood work done before taking any supplement with iron to ensure you won’t be taking in an excess amount. If you believe you already get enough iron, we recommend avoiding multivitamins with iron entirely.

Another thing to consider is just because you’re deficient in some vit/min it does not automatically mean you don’t provide enough with your diet. Absorption might be impaired somehow and taking more won’t necessarily solve the problem.

If you find yourself deficient in any vitamin or mineral but you’re eating well and even supplement yourself with multivitamins/minerals, we highly recommend paying a visit to your healthcare provider.

What Else Is Important to Consider?

While the points above should be able to help you make an informed choice, below we’ll be covering a few additional points so you can make the most out of a multivitamin supplement.

1. More Vitamins / Minerals Are Not Necessarily Better

First, as we briefly touched on above, understand that more vitamins/minerals do not make a supplement more effective.

2. You May Take Fewer Capsules Than Indicated by the Manufacturer

Continuing with the point above, if you choose a supplement that contains especially high doses of all its vitamins and minerals, you may be able to take fewer capsules than what’s recommended. 

Especially if a supplement’s recommended dose is between 2-4 capsules, it’s super easy to split up into multiple servings. This will not only save you some money, but it will help relatively small packages last much longer! Just keep in mind that you may be getting some low doses of certain vitamins/minerals if the supplement’s doses aren’t very balanced. 

Of course, this advice only applies to supplements that contain unnecessarily high doses of their ingredients. As a result, you’re likely better off just buying a supplement like Kirkland’s multivitamin that’s effectively dosed and comes in a large package.
