Rainbow Light Men’s One Multivitamin Review

In the early days of the company, as researchers studied Rainbow Light’s first product offering, spirulina, they noticed it refracted all colors of the rainbow while under a light spectrophotometer. Powered by nature and viewed through the lens of science, this led to the company name, and in 1981 there in the small Northern California town of Santa Cruz, Rainbow Light was born. 

Today, spirulina continues to play a key role in all their product offerings, which include Rainbow Light Women’s One and Rainbow Light Prenatal One, as well as other multivitamins, customized blends of nutrients, and targeted superfoods. 

Here’s a look at one of their signature products, Men’s One Multivitamin, which is a one-a-day multi that is the perfect solution to your modern nutritional needs in these modern times. Let’s see if this supplement is truly worth the cost, though, in this review of Rainbow Light Men’s One Multivitamin.

About Rainbow Light Men’s One Multivitamin 

Our modern food supply lacks the nutritional density it once had. This is due to soil depletion from our modern farming methods, as well as genetic modifications and increased time from harvest-to-table. 

Altogether, this means your daily needs for essential vitamins and minerals may not be met through diet alone, even if yours is high in fresh fruits and vegetables. That’s why adding a high-quality, food-based multivitamin to your daily regimen is important, which is what Rainbow Light is here to provide. Not only does their convenient, one-a-day formula give you a full spectrum of essential vitamins and minerals, they also add their organic rainbow vibrant foods blend, vitality blend, and digestive health blend to ensure all your male health and nutritional needs are met.

Rainbow Light Men’s One Multivitamin Benefits

Clinically Proven Absorption Of Vitamins D, B2, B5, Folate, Calcium, And Zinc

While many multivitamins include massive quantities of essential minerals and vitamins, that only matters if your body can absorb it all. But even though natural and synthetic vitamins are nearly identical in chemical makeup, your body reacts differently to them. This includes better absorption and a safer product with natural vitamins, since there is evidence that synthetic folic acid may be harmful. 

Plus, unnaturally high levels of oil-soluble vitamins may also lead to vitamin toxicity as they build up in your system. 

Supports Immune Health With A High Potency Source Of Zinc

When it comes to immune health, zinc is your friend; and when it comes to prostate health, zinc is your best friend. That’s because zinc is not only a powerful immune booster; it’s also essential in the production of testosterone and gonadal health. This includes helping reduce your risk for erectile dysfunction, the flu, and the common cold as well as other areas of immune and male hormone health.

With Rainbow Light’s formula, you get a 11mgs of highly absorbable, high-potency zinc to not only help you stay healthy during colds, flus, and pandemics, but ensure your prostate is as healthy and productive. 

Men’s Vitality Blend Of Green Tea And Lycopene

With the exception of skin cancer, prostate cancer is the most common type of cancer among men. This is why it is essential that you protect yours, which both green tea and lycopene can help do. 

That’s because both are potent antioxidants with evidence showing they can reduce the risk of prostate and other types of cancer. This includes colorectal cancer, which is the third most common type of cancer in men behind skin and prostate cancer, respectively. 

Gentle On The Stomach With Digestive Support Blend

While a daily multivitamin can help you feel your best, some aren’t so easy on your stomach. Plus, your digestion is an important part of your overall health and is key in maximizing your nutritional uptake. 

But the good folks at Rainbow Light realize this, which is why they avoid the use of synthetic vitamins that may be hard on the stomach in favor of easily digestible food-based vitamin. They also include their digestive support blend to ensure you get enough digestive enzymes, probiotics, and soothing compounds to ease your stomach and optimize digestion.

Rainbow Light Men’s One Multivitamin Ingredients

Rainbow Light Men’s One Multivitamin includes a variety of ingredients and blends. Let’s take a closer look at the main ingredients below.

Rainbow Light Men’s One Multivitamin Supplement Facts

Full Spectrum (minimum 100% RDA of most) Of Food-Based Vitamins And Minerals 

The basis of any multivitamin is, of course, the vitamins and minerals they supply, though despite many multi’s stating high vitamin and mineral content, not all are absorbable. This usually means that your expensive multivitamin is really not much more than…expensive urine, which is exactly what that bright yellow stream you’re flushing away with most multis is.

But by avoiding synthetic or overly processed vitamin and mineral compounds in favor of natural food-based ones, Men’s Daily One ensures you absorb optimum amounts of the very nutrition you seek. This includes water-soluble B and C vitamins, as well as oil-soluble vitamins A, D, E, and K, along with essential minerals such as calcium, magnesium, iodine, and zinc. You also won’t find outlandishly high doses, since, in the case of water-soluble vitamins, it’s mostly just a waste (see “expensive urine” above), and oil-soluble vitamins can also build up to toxic levels in your system if used excessively. 

But Men’s One is careful to balance nutrition with your body’s needs, and also ensures maximum absorbency. This means your nutritional needs for bone health, heart health, hormone production, and many other areas of male health are optimized so that your risk for chronic disease is minimal, and you feel great. 

Organic Rainbow Vibrant Foods Blend 100 mg

While vitamin compounds can be refined and isolated away from food compounds, they don’t offer the full synergistic benefits of everything in the plant when they are. 

But Rainbow Light not only includes food-based vitamin compounds in their formula, but they also include organic spirulina, beetroot, broccoli, kale, spinach, blackberry, blueberry, carrot, and cranberry. This helps ensure you get plenty of antioxidants, fiber, urinary tract support, and other beneficial plant compounds daily. 

Plus, green foods like spirulina, kale, and spinach are superfood powerhouses that provide highly bioavailable trace minerals and phytonutrients to add to the product’s nutritional content and lower your risk for cancer, heart disease, type II diabetes, and many other chronic health conditions.  

Men’s Vitality Blend 51 mg

Men need to protect their prostate and immune system, both of which the vitality blend in Men’s One will help optimize. That’s because the chlorella, green tea extract, and lycopene in Men’s One are all potent antioxidants that can help reduce your risk of prostate cancer. This goes along with the 11 mg of zinc citrate included in the vitamin and mineral blend to ensure your prostate is healthy and functioning, and your androgen levels are at their best. 

Plus, there’s that whole cold-and-flu season to make it through, which the immune-boosting properties of zinc and chlorella help with, and chlorella is also rich in antioxidants, vitamins, minerals, protein, and omega 3 fatty acids, all of which help keep your prostate functioning at its best. 

Digestive Support Blend 27 mg

Digestion also plays a key role in your overall health, and Men’s One delivers a blend of digestion-friendly ginger root, enzymes, and probiotics. This includes a spectrum of digestive enzymes that create chemical reactions throughout your digestive tract to break down foods and allow nutrients to be absorbed with maximum efficiency. Digestive enzymes also play a role in balancing your body’s pH levels. 

Men’s One also includes ginger root to soothe digestion and reduce the occurrence of gastrointestinal disorders. 

Does Rainbow Light Men’s One Multivitamin Work?

Banking on our modern food supply for all your nutritional needs may leave you short of a few key elements, and you’re probably also busy and on-the-go, which makes eating right hard, to begin with. 

This is why shoring up your daily nutrition with a high-quality, food-based multivitamin is in your best interest, and with its men’s-specific formulation delivering prostate, immune, digestive, and overall health benefits, you can’t do wrong with Rainbow Light’s formula. 

That’s because they formulate it using green-foods and other nutritionally dense compounds to deliver vitamins and minerals along with other synergistic elements to achieve maximum absorption, potency, and bioavailability. 

In other words, it’s not just expensive pee!

Who Is Rainbow Light Men’s One Multivitamin Best For?

In our modern world, nearly all of us could use a nutritional bump. This includes men of all ages who, in addition to relying on our nutritionally sparse modern food supply, may be a little “male” in their eating habits (a 7-course meal? That’s a burger and a six-pack, right?). 

Plus, since everything in Rainbow Light’s men’s formula are either essential vitamins and minerals, food, enzymes, or probiotics, there is very little chance of side effects or allergens, so nearly all can use it. 

But, if you already take high amounts of oil-soluble vitamins, it may not be a good idea to add yet more to your daily intake due to the risk of buildup to toxic levels, and those using prescription medications should also consult with their doctor before supplementing with vitamins.

Claims vs. Reality

The reality is that Rainbow Light Men’s One is highly absorbable and beneficial to nearly all men, and Rainbow Light being the ethical, health-conscious company they are, make no false claims on this product. 

Remember, poor nutrition also affects how you think and feel, and supplementing with Rainbow Light’s formula will not only lower your risk for chronic disease, but help you think more clearly, feel great, and have the energy you need for success in all your endeavors (and that includes, ahem, pleasing the missus, if you know-what-we-mean). 

Not to mention some vitamins work differently depending on when you take your multivitamins.

Is Rainbow Light Men’s One Multivitamin Safe?

Mostly, supplementing with multivitamins is as safe as can be, especially considering most of what’s in them are compounds essential to your existence. 

But while excess water-soluble vitamins are excreted through urine, high doses of vitamin C can cause gastric upset, and B-complex vitamins can cause gastric upset, high blood pressure, liver damage, and skin lesions. Granted, this is under extremely high amounts that may be hard to attain even with supplements, though it is reason to stay within recommended dosages.

Oil-soluble vitamins, on the other hand, can build up in your system and lead to such conditions as nausea, vomiting, irregular heartbeat, bleeding, coma, and death, so minding oil-soluble vitamin levels is a little more critical than with water-soluble.

Granted, it isn’t likely you’ll reach toxic levels of either water or oil-soluble vitamins unless you’re doing something silly like taking half-a-bottle per-day, though it is still something to be aware of. 

Where To Buy Rainbow Light Men’s One Multivitamin
