Rainbow Light Men's One Multivitamin
Rainbow Light Men’s One Multivitamin is not so much of a multivitamin as it is a general health supplement. It combines some standard vitamins and minerals – along with some choline bitartrate – with lots of plant powders, herbal extracts, and enzymes. We think a multivitamin should be just that; a multivitamin. The Rainbow Light Men’s One Multivitamin formula is overcrowded, confused, and imbalanced. The ingredient quality is also substandard. Better multivitamins are available for sure.
Rainbow Light Men’s One Multivitamin review: What does this supplement do?
Rainbow Light Men’s One Multivitamin is a brand new vitamin and mineral supplement. Although it hasn’t been on the market for very long, it is already receiving rave reviews, and thousands of people are searching for it online every single month. Why has this multivitamin become so popular? Why are Rainbow Light Men’s One Multivitamin reviews so positive?
According to the bottle, Rainbow Light Men’s One Multivitamin provides nourishment for the body “for energy and vitality”. The website lists several things they see as key selling points:
- Clinically proven absorption of key nutrients
- Supports immune system function
- Men’s vitality blend
- Gentle on the stomach
The first two promises are what we expect to get from every multivitamin; if a vitamin supplement doesn’t provide immune system support and bio-available forms of key nutrients, there’s no point in taking it!
The final two promises are more interesting though. Multivitamins generally don’t promise benefits like boosting male vitality or improving digestion. Although many vitamins and minerals are essential for male vitality, multivitamins don’t usually market themselves that way.
So, how much of this is true and how much of it is hype?
Does Rainbow Light Men’s One Multivitamin really work? Is it worth the money? Will it cause side effects? Is there a better multivitamin for men on the market right now? Read our full Rainbow Light Men’s One Multivitamin review below and find out.

Note about the formula
Rainbow Light Men’s One Multivitamin is composed of vitamins, minerals, and several proprietary blends. Whatever the circumstances, we advise you to avoid proprietary blends. They are usually a sign that you’re over-paying for a supplement (since there’s no reason to hide ingredients serving sizes other than to conceal formula stuffing). We haven’t bothered listing the individual ingredients from the blends as we have no idea how much there is in a serving of Rainbow Light Men’s One Multivitamin.
We’ll now go through each part of the formula one by one, explaining what it does, what the available scientific evidence has to say, and what we make of the servings. Then we’ll tell you what we make of the Rainbow Light Men’s One Multivitamin formula as a whole. Please post your questions in the comments at the end.
Vitamin & Mineral Stack
The Rainbow Light Men’s One Multivitamin vitamin and mineral stack is not bad. It provides all of the basic, staple ingredients that you need to get from a multivitamin; those most important for health and performance, and those that men are most likely to lack.
We get Vitamin A for healthy eyes, skin, and bones, Vitamin C for immune system function, and Vitamin E for its antioxidant action. We also get a fair amount of Zinc, Vitamin D, and Pantothenic acid, which are all vital for normal testosterone synthesis (and by extension, male vitality). Importantly, we also get good servings of iodine and chromium – nutrients which most men lack because of the scarcity of seafood and cruciferous vegetables in the diet.
It’s worth noting that, on the whole, the ingredient quality is extremely poor here. We only get very basic forms of each ingredient, or forms that are already ubiquitous in the diet. For example, we get Vitamin K, not K2. We get Vitamin D, not D3. We could go on. This is extremely disappointing. The best multivitamins for men on sale today all exclusively use highly-bioavailable forms of the key vitamins and minerals, and they always contain the most important form – you’ll never see Vitamin K1 in a professional quality vitamin supplement designed for men. It will always be K2.
The doses are also quite small across the board here. Considering this is a “male vitality multivitamin”, we expected a lot more Zinc, Vitamin D, and some Boron too (of which there is none at all). More on this in the discussion section.
Organic Rainbow Vibrant Foods Blend
On the whole, we don’t like “whole food” supplements. We think the idea of a “whole food supplement” is nonsensical; it goes against the only purpose in taking a supplement, which is to get particular nutrients into your body as efficiently as possible. Whole food should be eaten as food, and if anything is lacking from your diet, or you need certain nutraceuticals to enhance performance, you should supplement with them.
The “whole food blend” in Rainbow Light Men’s One Multivitamin is extremely basic – nothing we haven’t seen a thousand times before. These blends always go for the same “healthy sounding” ingredients: kale, spinach, blueberry, cranberry, etc. These are all great foods to eat, but they offer no benefits as supplements (unless you aren’t eating any nutritious food at all). We would much rather a supplement provide us with a large, concentrated dose of the antioxidants found in cranberries than just giving us cranberry powder. We’d rather just drink cranberry juice!
Leave whole foods for your meals. Use supplements to get large quantities of concentrated extracts which enhance health and performance. If you think cranberry powder can help, save yourself serious money and just drink more cranberry juice!
Men’s Vitality Blend
There is absolutely nothing about this blend which screams “male vitality” to us. Rainbow Light Men’s One Multivitamin doesn’t look like a man’s multivitamin to us at all so far!
While every stack varies, we have a rough idea of what a male vitality stack should look like: it needs vitamins and minerals which promote testosterone synthesis, reduce estrogen activity, and rectify the most common nutrient deficiencies in men. Rainbow Light Men’s One Multivitamin provides none of that!
Instead of comprehensive testosterone support, we get some green tea extract, some chlorella (which is stuffed into every greens powder these days), and some lycopene (an antioxidant found in lots of fruits and vegetables). None of these ingredients are going to have any discernible effect on your energy levels, libido, mood, or any other measure of vitality.
Digestive Support Blend
We think the inclusion of a digestive complex alongside a vitamin and mineral stack is a very good idea. One of the big problems with your run-of-the-mill multivitamins is that they usually provide poorly bioavailable forms of all the key nutrients. This means very little of the vitamins and minerals in the supplement end up in our bloodstream where your body can use them; instead, they’re just passed out.
Adding in key enzymes and digestion aids will encourage greater uptake of the most important vitamins and minerals in Rainbow Light Men’s One Multivitamin. It will also support proper digestion of food, meaning greater micronutrient uptake from your meals too. So a digestive complex has a compounding effect when used alongside multivitamins.
Inositol is a carbocyclic sugar. It is a naturally-occurring compound found in great abundance in the human body. It is particularly prevalent in the brain, where it is used for modulating the activity of hormones, neurotransmitter, and neuropeptides.
Inositol is sometimes taken as a supplement to relieve anxiety. There is actually some good evidence to support the use of inositol as an anxiolytic. Studies have shown that inositol consumption acutely reduces the symptoms of anxiety. However, these studies all used 500mg per day, while Rainbow Light Men’s One Multivitamin only gives us 20mg – barely enough to even register!
Citrus bioflavonoids are antioxidants obtained from citrus fruits. There are lots of bioflavonoids, many of which have extremely powerful antioxidant effects in the human body, helping to protect your cells from free radical damage.
It is a good idea to keep your antioxidant profile nice and high by eating lots of colorful fruits and vegetables every day. Drinking things like green tea and fruit juices will help make sure you have lots of antioxidants in your blood to minimize free radical damage.
However, we don’t think citrus bioflavonoids are really necessary in a multivitamin supplement. These aren’t particularly powerful antioxidants as a group, especially not compared to some of the antioxidants found in professional quality supplements today. Rainbow Light Men’s One Multivitamin yet again gives us an ingredient that sounds vaguely healthy, but in reality should be obtained from food – not worth the premium price tag.
Our analysis: Is the Rainbow Light Men’s One Multivitamin formula any good?
We can’t say we’re overly impressed with this multivitamin. As far as men’s vitamin supplements go, this is a very underwhelming specimen.
Rainbow Light Men’s One Multivitamin claims to be a professional quality, premium, market-leading vitamin supplement for men. It claims to deliver not just nutrient and immune system support, but male vitality support and digestion support too.
Unfortunately, we don’t think it even comes close to delivering on these promises.
The vitamin and mineral stack is as basic as it gets. We are just given the standard, most common forms of every ingredient. It is a standard requirement for us that multivitamins give us the forms of the vitamins that are going to have the biggest effect on our health and performance. This means Vitamin D3 instead of plain D, K2 instead of K1, and so on.
Rainbow Light Men’s One Multivitamin gives us just the standard form of each vitamin and mineral – no bioavailability enhancement, no extra effort to provide those nutrients most lacking in the diet (e.g. K2 instead of the ubiquitous K1), nothing.
Then there’s the dosing problem – the serving sizes are tiny in this vitamin supplement!
Rainbow Light Men’s One Multivitamin delivers relatively small doses of almost every ingredient. Absorption from multivitamins is never 100%, so we prefer supplements to give us over 100% of the most important vitamins and minerals (to ensure we get properly topped up). But this product gives us small doses of even the most important minerals and vitamins for men’s vitality.
This brings us neatly onto our final major problem with this supplement – IT’S NOT A MALE VITALITY SUPPLEMENT!
Despite explicitly promising to provide vitality support for men, we don’t see a single ingredient capable of significantly increasing any measure of male vitality, be it strength, energy levels, confidence, or libido. There is no testosterone support in Rainbow Light Men’s One Multivitamin, and the vitamins and minerals that do affect testosterone are dosed quite low.
All things considered, this is a poor multivitamin.
We don’t know how so many positive Rainbow Light Men’s One Multivitamin reviews are out there, because this strikes us a distinctly average multivitamin. There is no way this price tag can be justified.
If you’re looking for a high quality multivitamin designed specifically for men, then we think you can do a lot better than Rainbow Light Men’s One Multivitamin. We think this is an incredibly over-priced supplement offering low quality ingredients and little support for men.
Side effects: Is this men’s multivitamin safe?
How safe is this men’s multivitamin?
This might seem like a strange question – are multivitamins ever dangerous?
While most multivitamins are safe for practically everybody to use on a daily basis, some irresponsible manufacturers do put in extremely large doses of vitamins and minerals that will eventually cause you problems.
With vitamins and minerals, more is not always better.
Taking too much of some vitamins is practically impossible – as with most of the B Vitamins – but for others it can have dire consequences. Even taking too much of certain minerals for a short time can cause minor side effects, such as stomach cramps and lethargy.
So is Rainbow Light Men’s One Multivitamin safe?
The answer is yes. This looks like a safe multivitamin to us. Rainbow Light Men’s One Multivitamin doesn’t contain any excessively-large mega-doses of vitamins or minerals (we’re actually worried this supplement is under-dosed). The proprietary blends don’t contain anything that gives us serious cause for concern.
The only possible side effect concern with Rainbow Light Men’s One Multivitamin is the digestive complex. Consuming enzymes like this – in large quantities all at once – might cause digestive problems for some people, including:
If you experience any of these side effects, stop taking Rainbow Light Men’s One Multivitamin immediately and seek medical attention.

Summary: Is Rainbow Light Men’s One Multivitamin a good choice?
Should you buy Rainbow Light Men’s One Multivitamin?
The answer, in our opinion, is a resounding “nope”.
This is a very basic multivitamin. Despite its claims about being a professional-quality, market-leading stack, Rainbow Light Men’s One Multivitamin is not an impressive product by any measure.
For starters, the actual vitamin and mineral content is nothing you wouldn’t get from a cheap multivitamin bought from a supermarket. In fact, you might get larger doses from a supermarket multivitamin for a fraction of the price.
There’s no male vitality support in this supplement, even though it explicitly claims to boost male vitality. There’s no testosterone support at all, apart from a low dose of Zinc and some Vitamin D.
Then there’s the use of proprietary blends and unnecessary ingredients. We advise you to stay away from proprietary blends in any circumstances, and that applies to Rainbow Light Men’s One Multivitamin as well. Prop blends are always just a tell-tale sign that you’re being ripped off; there’s simply no other reason for a supplement manufacturer to use them.
The digestive complex is a welcome addition, but it doesn’t do enough to balance out the problems with this formula (and it has side effect issues of its own).
All-in-all, this is far from a great multivitamin. Poor value for money, low quality ingredients, and a lack of male vitality support let this men’s vitamin supplement down.
If you’re in the market for a quality men’s multivitamin, this is not it. Regardless of your particular needs, the best multivitamins for men on sale today offer far better value for money and significantly better results.
