I’m going to be honest with you. Most multivitamins are basically expensive rocks. You swallow them, your body looks at that hard-pressed tablet of synthetic fillers and binders, and says "no thanks." They often pass through your system without even breaking down. That’s exactly why Source of Life liquid vitamins by Nature’s Plus became such a cult favorite in the health world. It’s a thick, weird-looking, tropical-flavored liquid that looks like swamp water but acts like a high-octane fuel injection for your cells.
If you’ve spent any time in a local health food store, you’ve seen it. The yellow bottle. The gold cap. The promise of "Source of Life." But does it actually do anything, or is it just clever marketing and a bit of caffeine-free placebo?
I’ve spent years looking into supplement bioavailability. The science is pretty clear: liquids generally win. When you skip the "breakdown" phase required by tablets, your body can get to work on absorption immediately. Nature’s Plus claims their Source of Life Gold formula is the "gold standard" of whole-food energizing multivitamins. They aren't just tossing in isolated vitamins like Vitamin C or B12; they are packing in over 120 whole foods. It’s dense. It’s messy. It’s expensive. And for a lot of people, it’s the only thing that actually stops that 2:00 PM brain fog.
What’s actually inside Source of Life liquid vitamins?
You can’t talk about this stuff without talking about the ingredients list. It’s a mile long. Seriously. While your standard drugstore multivitamin might have 20 or 30 ingredients, Source of Life Liquid is a literal grocery list of superfoods. We’re talking about a "Gold Standard Whole Food Complex" that includes things like guava, holy basil, lemon, and amla.
It’s not just about the vitamins. It’s the co-factors.
Nature’s Plus leans heavily into the idea that vitamins shouldn’t exist in a vacuum. In nature, you don’t find a pure crystalline Vitamin C molecule sitting on a rock. You find it inside an orange, surrounded by bioflavonoids, fiber, and enzymes that help your body recognize and use it. Source of Life liquid vitamins try to mimic that. They include a "Multi Color Whole Food Blend." This isn't just marketing fluff; it includes things like spirulina, chlorella, and juice solids from pomegranate, acai, and goji berries.
The Bioavailability Factor
Why go liquid? Simple. Absorption. A study published in the Journal of Clinical Pharmacology years ago highlighted that liquid medications and supplements can have significantly higher absorption rates than their pill counterparts. When you drink your vitamins, you bypass the need for the stomach to mechanically grind down a tablet. This is a game-changer for people with digestive issues, low stomach acid, or those who have had gastric bypass surgery. If your gut is compromised, a pill is a waste of money.

Nature’s Plus uses a "Smartseed" blend and prebiotic fibers to further help the gut process this dense nutritional load. It's thick. If you don't shake the bottle, the good stuff settles at the bottom. You’ll end up with a watery sip at the start of the month and a sludge at the end. Don't do that. Shake it like your life depends on it.
The Energy Myth: Is it Caffeine?
A common question I get is: "Why do I feel a buzz after taking this?"
People often assume there’s a hidden stimulant. There isn't. The "energy" people feel from Source of Life liquid vitamins usually comes from the massive dose of B-vitamins—specifically B12 (as methylcobalamin) and B6. These are essential for the Krebs cycle, which is how your mitochondria actually produce ATP (energy).
When you’re deficient in B-vitamins, you feel like you're walking through mud. When you flood your system with a highly absorbable liquid form, the lights turn on. It’s not a jittery caffeine high. It’s more of a "I forgot I was tired" kind of feeling.
However, we need to talk about the sugar.
Honestly, the taste is "love it or hate it." It’s a tropical flavor, but because of the sheer volume of greens and minerals, it has a distinct metallic, earthy undertone. To make this palatable, Nature’s Plus uses a mix of fructose and other sweeteners. If you are strictly keto or watching your glucose spikes, you need to be aware that the liquid version does have a few grams of sugar per serving. For most, the 20-30 calories are worth the nutritional payoff, but it’s a trade-off you should know about.
Is the "Gold" Version Worth the Extra Cash?
There are several versions of this stuff. You have the "Original" and the "Gold."
The Gold version is significantly more expensive. Why? It adds Vitamin D3 (as cholecalciferol), Vitamin K2 (as menaquinone-4 and menaquinone-7), and a broader range of organic whole foods. If you already take a separate Vitamin D supplement, you might be fine with the original. But if you want a "one and done" solution, the Gold formula is arguably one of the most complete liquid supplements on the market. It even includes trans-resveratrol and CoQ10 for heart health and aging.
The Downside: What Nobody Tells You
Nothing is perfect. I’m not here to sell you a miracle in a bottle.
First, the price. It’s expensive. A 30-day supply can run you anywhere from $40 to $60 depending on where you shop. Compared to a $10 bottle of generic pills from a big-box store, it's a jump.
Second, the storage. This isn't a "leave it on the counter" supplement. Once you open Source of Life liquid vitamins, they must be refrigerated. If you leave it out, the organic whole food components will oxidize and spoil. I’ve heard horror stories of people taking a swig of room-temperature liquid vitamins that had been sitting out for a week. Don’t be that person.
Third, the stains. This liquid is a vibrant, neon yellow-orange. That’s the riboflavin (Vitamin B2) at work. If you spill this on a white countertop or a light-colored shirt, consider it a permanent design choice. It stains everything.
Iron: A Word of Caution
Most versions of Source of Life liquid vitamins contain iron. For women of childbearing age or people with iron-deficiency anemia, this is great. It’s a highly absorbable form. However, if you have hemochromatosis or if you’re a man who already eats a lot of red meat, you need to be careful with long-term iron supplementation. Always check the label—Nature’s Plus does make "No Iron" versions of some of their products, but the liquid often defaults to including it.
How to actually take it for best results
Don't just take a shot of it on an empty stomach.

I know the label says you can, but for many people, the high concentration of zinc and B-vitamins can cause a bit of "vitamin nausea" if there’s no food in your belly. The best way? Mix your 2-tablespoon serving into a morning smoothie or a small glass of orange juice.
- Shake it. I mean really shake it.
- Measure it. Use the cap or a measuring spoon. Don't just "glug" it.
- Drink it with breakfast. The fats in your meal will help you absorb the fat-soluble vitamins (A, D, E, and K).
- Hydrate. B-vitamins are water-soluble. Your kidneys will be working to filter the excess, so drink plenty of water throughout the day. Your urine will likely turn neon yellow. Don't panic. That's just your body processing the riboflavin.
Real World Results: What Can You Expect?
If you start taking Source of Life liquid vitamins today, you aren't going to turn into a superhero by Tuesday. Supplements are about the long game.
Usually, within the first week, people notice a shift in their "afternoon slump." Instead of reaching for a third cup of coffee at 3:00 PM, you might just realize you're still focused. Within a month, many users report better nail growth and clearer skin, thanks to the silica and biotin buried in that whole-food blend.
But listen, if your diet is 90% processed trash, no liquid vitamin is going to save you. It’s a supplement, not a replacement. It fills the gaps that modern industrial farming leaves in our produce. Even "organic" spinach today has fewer minerals than the spinach our grandparents ate because of soil depletion. That’s where this liquid shines—it acts as a nutritional safety net.
The Verdict on Source of Life
Is it the best liquid multivitamin? It’s certainly in the top three. Brands like MaryRuth’s offer a cleaner, sugar-free alternative, but they often lack the sheer "whole food" density that Nature’s Plus provides. If you can handle the taste and the price tag, Source of Life is a powerhouse.
It’s specifically great for:
- Seniors who have trouble swallowing pills.
- Athletes who need rapid nutrient recovery.
- People with "malabsorption" issues (IBS, Celiac, etc.).
- Anyone tired of taking 10 different pills every morning.
Actionable Next Steps
If you’re ready to try it, start with a smaller 8oz or 16oz bottle before committing to the giant 30oz one. Taste is subjective, and you don't want to be stuck with a half-gallon of something you can't stomach.
Check the expiration date before you buy. Because of the whole-food nature of the product, it has a shorter shelf life than synthetic pills. Buy from a reputable source that rotates their stock frequently.
Once you get it home, clear a spot in the fridge. Take it consistently for 30 days. Most people quit supplements after three days because they don't see a "glow-up" in the mirror. Nutrition doesn't work like that. It’s a slow build.
Lastly, talk to your doctor if you're on blood thinners. The Vitamin K in the Gold version can interfere with medications like Warfarin. Be smart about it. Supplementing should be the easiest part of your health journey, not a source of stress.
Start by taking your first dose with a solid breakfast tomorrow morning. Pay attention to your energy levels around mid-afternoon. That’s where you’ll see the real difference.
