Overview of the Rainbow Light Men’s One

Rainbow Light Men’s One has a very down-to-earth description page. At first it may seem that it does not pose or affirm itself to be the best of anything. But then you’ll find this writing on the supplement itself “#1 Natural Men’s Multivitamin Brand”. The description page, however, does not go that far.[1]

In this Rainbow Light Men’s One review we will take an in-depth look at how good the supplement actually is.

Let’s go.

*If you’re interested in a less scientific, all ingredient-considered content and more interested in the highlights and interesting facts on the supplement, while also giving you the essential information, take a look at this article.*

Nutrient Amounts & Efficiency

Vitamins Overall Are In Quite A Decent Shape

Rainbow Light Men’s One has all of the essential vitamins: Vitamin A, B1, B2, B3, B5, B6, B7, B9, B12, C, D3, E, K1 and Choline. Whereas, the amounts of particular ones are not always enough. Also the forms of many vitamins are not the best for intake.

Overall Assessment of Vitamins for the Rainbow Light Men's One

Vitamin A in Rainbow Light Men’s One comes in both of the very needed forms: the preformed form of Vitamin A and Beta-Carotene (a carotenoid). Although, greater variety of carotenoids would be very much desirable, having at least one is better than none. All in all though, it’s very hard to judge the actual amounts of any of these two forms as they are not specified separately on the label of the supplement.[2] [3] [4] [5] [6] [7] [8] [9] [10]

Vitamin B1, B6, B9, B12, C and Choline are in forms that are most often found in multivitamin supplements and supplements in general. Yes, these are not as effective and beneficial as some of the other forms for these particular vitamins. But, nonetheless, they’re not bad for consumption.[11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] [23] [24] [25] [26] [27]

On the other hand, however, we got Vitamin B2, B3, B7, D3 and K1, all of which are arguably in the most effective and overall the best forms for these vitamins possible.[28] [29] [30] [31] [32] [33] [34] [35] [36] [37] [38] [39]

There are two more vitamins that this supplement has and that do ask for a longer analysis.

Vitamin B5 being labeled as Calcium Pantothenate doesn’t really say much. This is because there are two forms of Calcium Pantothenate: Calcium-D-Pantothenate and Calcium-L-Pantothenate. Just saying Calcium Pantothenate could mean any one of these forms. However, the difference between these two is huge, because the “L” form is only about half as effective as the “D” form.[40] [41] [42] [43] [44]

As this is clearly not shown on the label of Rainbow Light Men’s One, it is far more than just likely that this supplement contains the “L” form (the ineffective form). I mean, is there like another reason to not otherwise label it clearly? I doubt that.

Vitamin E as D-Alpha Tocopheryl is a great form to have in a multivitamin supplement. But Vitamin E is much more than a single tcopheryl form. In fact, there are in total 8 forms of Vitamin E, all of which should ideally be a part of the multivitamin supplement.[45] [46] [47] Therefore, overall having only one form of Vitamin E is not sufficient.

Other than that, also the amount in which this single form of Vitamin E is present in the supplement is by far too insignificant (see Prime Daily Values).

Other low-amount vitamins in the supplements are Vitamin B3, B5, B12, C and Choline. And surely there is also that lack of variety of Carotenoids.

Minerals Are Only Half Of What’s Needed

Rainbow Light Men’s One contains about a half of all minerals needed daily. This supplement has Calcium, Magnesium, Zinc, Selenium, Copper, Manganese, Chromium, Molybdenum, but both Calcium and Magnesium are in quite miserable amounts. And the minerals missing completely are Iodine, Boron, Vanadium and Potassium.

Overall Assessment of Minerals for the Rainbow Light Men's OneCalcium in its form is a pretty weak option to choose from. There are many much better forms out there.[48] [49] The same can be said about Magnesium.[50] [51] [52] [53] Unfortunately, also both of these minerals are in terribly low amounts.

Zinc in its form is one among many of the most effective forms for this vitamin.[54] [55]

Selenium is present in the form that is one of the two best possible options.[56] [57]

Supposedly, Copper comes in a form that is one of the best choices.[58] [59] [60] [61] [62] [63]

The form of Manganese is one of the best choices to have.[64] [65]

Chromium is in a form, that is pretty okay regarding absorption. Nonetheless, there is a form that is by far better than this one.[66] [67]  [68]

Molybdenum could be present in potentially the best form available. Yet, this is uncertain as it is only specified as “Molybdenum Amino Acid Chelate”. But there are many variations of Molybdenum Amino Acid Chelates each being different absorption wise. Therefore, we shouldn’t assume that it’s in its best form. Either way, any chelate is a good form.[69] [70]

In Terms Of Extra Substances Rainbow Light Men’s One Is A Masterpiece

There are quite a number of additional beneficial substances in Rainbow Light Men’s One. These include Inositol, Citrus Bioflavonoid Complex, Men’s Strengthening Blend, Vegetable Juice Complex and a Complete Digestive Support.

The last three of this list have many ingredients within them. Therefore, I used the names provided on the label for easier reference. I will be looking into more detail regarding them though. But first, lets get Inositol and Citrus Bioflavonoid Complex out of the way.

Inositol greatly supports brain function. Have you ever had or do you experience often anxiety or panic attacks? It helps with that. Have you got or are you on the edge of having a depression? It helps with that too. Are you in constant stress? It will help with it also. In fact, it helps also to heal conditions like Obsessive-Compulsive Disorder (OCD).[71] [72] [73] [74] [75] [76] [77] [78]

It is an incredible substance that can help you to achieve a calm mind and improve your overall brain function and capability.[79] [80] [81] [82]

Regarding the amounts – it is recommended to have a bit more of Inositol in your daily supplement, but this is also okay (see Prime Daily Values).

Citrus Bioflavonoids is like the second line of defense for your body, Vitamin C being the first. This is a substances found in most fruits and vegetables. It provides amazing antioxidative abilities (antiviral, antiallergic, antitumoral, antiplatelet, antihypertensive and overall anti-inflammatory abilities).[83] [84] [85] [86] [87] Thus, it is the substance, which helps to fight off most of the bad stuff your body might encounter.

Other than that, Citrus Bioflavonoid Complex is believed to improve heart, skin and blood vessel health.[88]

Next up is Men’s Strengthening Blend. According to the label it contains 66 mg of Saw Palmetto, 33 mg of Organic Spirulina and 1 mg of Lycopene.

Saw Palmetto is a berry that has many health benefits. Mostly these benefits are related to improving men’s well-being. Saw Palmetto provides amazing improvement to prostate’s health, reduces the possibility of Prostate Cancer, increases libido and also among many other is a great hair loss remedy.[89] [90] [91] [92] [93] [94]

Organic Spirulina is a blue-green algae, which is one of the most healthy (and I mean most healthy) plants on the planet. And it is also one of the most researched plants on the planet. The benefit list for this miraculous algae is pretty much inexhaustive.[95] [96] [97] [98] [99] [100] [101]

Some of the most significant benefits, in my opinion, for this plant are: it detoxes heavy metals from the body, improves immunity and helps to fight off cancer, possesses incredible amounts of nutritional content (has loads of various vitamins, minerals, proteins, amino acids and essential fatty acids), helps to improve blood sugar levels, lowers cholesterol levels and in general is an amazing antioxidant. But as I said, there are many, many more possible benefits of this wonderful plant.[102] [103] [104] [105] [106] [107] [108] [109]

No wonder it is often referred to as one of the world’s superfoods.

Lycopene is a very common substance for multivitamin supplements that are labeled as “for Men”. Nevertheless, it is a great substance also for women.[110] [111] [112] [113] [114] [115]

Lycopene has been known for slowing down and preventing all kinds of cancer, protecting DNA, improving bone, heart and skin health, as well as being a great antioxidant. Furthermore, it does have also some other benefits.[116] [117] [118] [119] [120] [121] [122] [123] [124] [125]

In the supplement we also have Vegetable Juice Complex. It is a vegetable powder made out of Kale, Spinach, Dandelion Greens and Beet.

With this powder you, basically, get all kinds of different additional nutrients to the basic nutrient forms of the supplement. Other than that, this complex is also definitely a good source of Dietary Fiber.[126] [127] [128] [129]

And then there is a mix labeled as Complete Digestive Support. And it is exactly that.

Protease is an enzyme that ensures the digestion of different kinds of proteins.[130] [131] [132] Amylase is an enzyme that does the digestion process of carbonhydrates.[133] [134] [135] Lipase is also an enzyme, but it is one that breaks down fats.[136] [137] [138]

Lastly, Cellulase is an enzyme that breaks down insoluble cellulose. But unlike other enzymes mentioned, this one is not also produced by human digestive system.[139] [140] [141] Most probably this enzyme is present in the supplement to ensure that the body can aquire nutritional value out of cellulose containing additives.

Bacillus Coagulans is an extremely beneficial probiotic bacteria. It is way more potent and superior than all of those in yogurt findable nonsense probiotics. Furthermore, it elevates the levels of other beneficial bacteria in the stomach, reduces the stomach pain, decreases the “Bad” blood cholesterol levels, enhances protein absorption, decreases bloating, constipation, vomitting and diarrhea and has other health benefits.[142] [143] [144] [145] [146] [147] [148] [149] [150] [151] [152]

I will be adding an article on why probiotics are important in the near future. But essentially, you could be taking all the nutrients from your multivitamin supplements and still fall ill, because of lack of nutrition. There are various reasons, why this may be, but the important thing to know is that probiotics 99.99% of the time can help.

Thus, having a built-in probiotics in your multivitamin supplements is extremely beneficial. Yet, I personally wouldn’t consider this as the best option. Stay tuned for that article! I’ll explain everything!

Betaine (also known as trimethylglycine) is an amino acid that is produced by the body and that has a vital role in methylation in the body. Or in other words, it is extremely needed for the body and mind to function well and at its best.[153] [154] [155]

Possible benefits of taking Betaine additionally with supplements are: it prevents heart disease and damage to blood vessels, improves endurance, improves the function of liver and detoxification and has other benefits.[156] [157] [158] [159] [160] [161] [162]  [163] [164] [165]

Additives Are All Harmless And Safe

In total there are 7 additives. All of these pose little-to-no threat to health. In other words, these additives used in Rainbow Light Men’s One are harmless and perfectly safe to intake.

Microcrystalline Cellulose and Hypromellose both are alterations of cellulose. Cellulose is one of the most abundant substances on earth found in wood and all plant structures. These two additives are believed to be safe to intake even in huge amounts. And even in huge amounts one will either encounter no side effects or for a few some bloating, constipation or diarrhoea might happen.[166] [167] [168] [169] [170] [171] [172] [173]

There has been some uncertainty regarding Stearic Acid as most of the internet do claim that it is a bad thing.

It is not.

Stearic Acid is not some T-cell (cells that fight cancer) killing substance as most claim. Well, it is in mouse, but not in humans. This is because human T-cells have enzymes to break down stearic acid, if it happens to build up too much. And there are some other claims that it is a bad substance, which are as easily refutable and not relevant.[174] [175] [176] [177]

A fun fact is that we on a daily basis more than just likely consume higher amounts of Stearic Acid than we would ever be able to get from supplements. In fact, even babies consume a lot (and I mean a lot) of Stearic Acid from mother’s milk.[178] Thus, it is harmless and a safe additive to intake long-term.

Modified Cellulose is a pretty blur and uncertain thing. Well, what I mean by that?

Any form of Cellulose that can be found in supplements can be considered as “modified”. Therefore, modified cellulose as an ingredient can be any one of the 15 different variations of cellulose. Typically, cellulose is not associated with particularly serious side effects (see before Microcrystalline Cellulose and Hypromellose analysis), but I am not sure if that can be said about all 15 variations of it.[179]

Silica or Silicon dioxide  – in plants, in animals, in water, in earth and of course also in our bodies – is a substance naturally found in a lot of things.[180] [181] Regarding its safety, long-term studies have shown no threat to health even when used in very high amounts.[182] [183]

MCT or Medium-Chain Triglycerides is a variation of healthy fats that can be used by the body immediatly (or also be converted into other necessary substances for the body).[184] [185] [186] [187] Regarding possible side effects – MCT’s will either have no side effects or in some rare cases it might cause upset stomach or diarrhea. Nausea and vomitting is also possible.[188] [189] [190]

Nevertheless, MCT is extremely beneficial to consume as it has quite a number of benefits to its name. Improved brain fuction, lowered cholesterol levels, boosted energy levels and improved weight management are just some of them.[191] [192] [193] [194] [195] [196] [197] [198]

Inulin is a soluble fibre that stimulates the growth of the beneficial bacteria in the gut (typically human gut contains 15 thousand to 36 thousand species of bacteria). It is also a common substance in many different fruits, vegetables and herbs.[199] [200] [201] [202] [203]

There are few possible side effects for this substance, which most of the time come in a form of stomach problems. Thus, some bloating, flatulence, diarrhea and abdominal discomfort may occur. Supposedly, if one does encounter these side effects drinking plenty of water can probably cure this. As with any additive though, in rare cases, if you do encounter an alergy, it might have some quite more serious side effects as well.[204] [205] [206] [207] [208] [209] [210]

However, Inulin is not particularly known for its side effects. It’s known for its benefits, which are quite many. Inulin stimulates the growth of beneficial bacteria, which improves digestion, immunity and overall health, relieves constipation, improves calcium absorption and has other benefits.[211] [212] [213] [214] [215] [216] [217] [218] [219]

Conclusions on Rainbow Light Men’s One

All in all Rainbow Light Men’s One is a pretty nice multivitamin supplement.

Rainbow Light Men’s One has all of the essential daily vitamins needed. The amounts of them are most of the time pretty relevant. It also has most of the essential minerals present in it. Most of their forms are very, very good and effective upon consumption. Also the additives are some of the safest for multivitamin supplements, which is incredibly good.

As far as other beneficial substances go, Rainbow Light Men’s One has some of the best I’ve seen for multivitamin supplements. Some of them, like Organic Spirulina and the Vegetable Juice Complex, make up for some of the extra vitamin amounts needed.

And the Complete Digestive Support kit does ensure that everything in the supplement is well digested and absorbed by the body.

But there are some, in my opinion, mayor lacklasters to its name.

Rainbow Light Men’s One provides only one form of Carotenoids, which is also insufficient in regard to amounts. And vitamins like B5, B12, C, E and Choline are seriously lacking. But overall only few of the vitamins are present in the best forms possible. And also Vitamin E comes only in one form.

While most of the minerals that are in Rainbow Light Men’s One are all good, it compleately lacks Iodine, Boron and Vanadium. Lack of Potassium is not really an issue as it is quite optional to have in a supplement. I do also dislike the inefficient forms of Magnesium and Calcium.

Ultimately, I do think that Rainbow Light Men’s One is a good supplement. However, there are way better options out there.

If you’re out on a hunt for a multivitamin, rather get one of those.

    Hi Matiss, stumbled upon your site and I’m glad I did. Thanks for the review, very informative. I just have a couple of questions.

    I think something you didn’t address in the review is the fact that you only need to take one tablet of this particular brand. I was having a browse of your top 11 and the majority seem to require 4-8 tablets a day. I’d be interested in your opinion of the best ‘all in one’ multivitamin. Between taking Omega 3, glucosamine, probiotic, magnesium and various nootropics, I’m actually trying to consolidate the amount of tablets I consume and try to increase the quality. Any chance of you compiling a list of the best multivitamins which only require one or two pills? Would this one be up there do you think?

    Also, I’ve done some research into the strain Bacillus Coagulans which is contained in this. It seems a good strain and I was initially hopeful it would reduce my need for the probiotic I currently take. Would you say the 25 million strains is substantial enough though? This particular strain seems to survive better in the gut than others, so hopefully the lower dose would be adequate. But I’ve noticed most probiotics of this strain seem to be in the billions, rather than millions though. Is the 25 million actually of any use and could it replace a good probiotic?

    Thanks for any response.

      Hey, Danny!

      I’m really happy you reached out! I was debating that thought in my own mind recently in regards to what could be the best 1-2 pill multivitamins. So, I guess this just proves the point that I should be adding a relevant section to the article. As I see it now, it could most probably come in a form of top 3-5 best ones in that category.

      As for now, in truth, I haven’t really done any extensive research for what those supplements could actually be. One that immediately comes to mind is the Thorne Research Basic Nutrients 2/Day (also available here). On that same note though, I believe the amounts of Chromium and Vitamin K might be too much for long-term. Anyways, I definitely have to look into it.

      Whether the Men’s One could be up there… In the past maybe, as of now, I’m skeptic about it. That of Basic Nutrients I mentioned pretty much outclasses it in regards to every single nutrient. However, if you were to go with a two tablet approach for the Men’s One it might be regarded as a solid one. Still, I think at the end of the day it won’t cut it for it to be at the top 5. But as I said, I have to do some research before I can say for sure.
      Is it okay if I drop you an e-mail within a week’s time once I have a more concrete answer, Danny? Or I can just post another comment here.

      As for the probiotics, those 25 million definitely is a good addition to the supplement but as I see it, there is no chance in the world that it could replace a solid probiotic supplement. It should ideally be 10-20 billion twice a day.

      I hope that helps! If you ever need anything, just let me know, Danny!

      Cheers, and Have a Great One!

        Hi Matiss,

        Thanks for the quick response, really appreciate it. I’ll take a look into the Basic Nutrients you linked to and have a look over it and see if it’ll suit my needs.
        Yeah, of course, would really appreciate any further info you could find for me, that’d be great. Just leave a comment here and I should find it next time I’m browsing your page. And I’m sure others would find benefit in your research too.

        Thanks for the info on the probiotics, I thought that might be the case so I’ll just stick to the one I’m using for now – Jarrow Formulas Saccharomyces Boulardii.

        Any idea on when you plan on releasing your list of the best Probiotics and any thoughts on the Jarrow one I linked?

        Cheers,
        Danny

          Hey, Danny!

          Yeah, I completely agree. 🙂

          I liked those probiotics of Jarrow Formulas. Love the fact that the additives are harmless within it. However, I wouldn’t say they’re the ideal option either. If nothing else then just the fact that you’d need to take 4 a day to get to that lower margin of 10-20 billion twice daily. I also remember something about the more diverse strains in the probiotic the better. Not sure where I got that from but I’ll definitely need to look into it.

          Either way, you can definitely stick with those of Jarrow Formulas. But if you plan to upgrade shortlist the Renew Life Everyday Ultimate Flora Probiotic. These are my go-to probiotics at the moment.

          As for that list on the best ones, at the moment I can’t really tell, Danny. They definitely are somewhere near the top of my priorities in regards to the best lists. But when I’ll get to them I’m not really sure.

          Cheers, Danny, and Have a Great One!

    Hi Matiss,
    Great review of Rainbow Lights’ One multi-vitamin. All in all it looks like a pretty good product but also sounds like in your opinion they are perhaps over hyping it a bit. In general though it looks pretty solid.

    It’s great to read this information. I have taken a men’s multi vitamin for years and honestly really did not think there was much of a difference between brands. This is great information to have, appreciate your sharing.

    All the best,

    Mat A.
