Our Picks at a Glance
How To Choose The Best Colloidal Gold
Colloidal gold is a suspension of ultra-tiny gold particles in pure water. Unlike an ionic solution where dissolved atoms float free, a true colloid holds nanoparticles in suspension, which many believe makes the gold more usable by your body. The challenge is that the label can say 20 ppm, 100 ppm, or 300 ppm, but the particle size (measured in nanometers) often matters more than the concentration. Smaller particles mean more surface area, which is why brands like MesoGold advertise “Highest Particle Surface Area” as the key metric. Start your search by looking past the ppm number and checking for particle size and purity claims.
Understanding PPM vs. Particle Surface Area
PPM (parts per million) tells you how much gold by weight is in the water. A 100 ppm bottle has five times the gold weight of a 20 ppm bottle. But particle size flips the script entirely. A product with 20 ppm but an average particle size under 3.2 nanometers can deliver more usable gold surface area than a 100 ppm product with larger, clumpier particles. So do not assume higher ppm automatically means stronger effects — look for brands that state both values.
Purity and Manufacturing Claims
Most reputable colloidal gold makers claim 99.99% pure gold as their starting material. The difference comes from how that gold is processed. Some use high-voltage electrolysis to suspend gold in distilled water with no salts, proteins, or additives. Others use chemical methods that may leave ionic gold residue, which looks clear rather than ruby-red. A true nanoparticle suspension has a visible ruby-red or pinkish hue because the small particles scatter light. Clear, water-like liquid is a red flag that the product may be ionic gold, which behaves differently in the body than a true colloid.

In‑Depth Reviews
1. MediGOLD® True Colloidal Gold AuNP – 500 mL
Our pick — over 4★ from 900+ verified ratings; the strongest balance of quality and price.
The 20-ppm workhorse that owners say sharpens focus and triggers vivid dreams from night one.
MediGOLD sits at a patient 20 ppm concentration, but the feedback suggests that lower ppm does not mean lower impact. The crowd favorite — buyers report mental clarity, better problem-solving, and what one described as “dramatically better creativity” after about a week of use. The manufacturer uses.9999+ pure gold nanoparticles suspended in pure water with no ionic gold, no color added, and no protein binders. The bottle is double-sealed for protection and is known for a long shelf life.
The consistency of praise here is notable. Many return for second and third bottles, calling it a trusted brand that has been in business for years. The most common thread is that people feel subtly different — less mental clutter, more fluent thoughts — without noticing a dramatic jolt. The 20 ppm means you need a larger dose per serving compared to a 100 ppm product; one experienced user notes they needed 2 tablespoons daily instead of the label’s 1 tablespoon to maintain the effect. The product dimensions are 3 x 3 x 7 inches, making it a compact bottle compared to the much larger MediGOLD 500 mL sibling.
The honest trade-off here is dosage concentration. At 20 ppm in a 500 mL bottle, you are getting a lot of volume for the price (the bottle contains a full 500 mL in a clear plastic container), but you will consume more liquid per serving than with a 100 ppm product. That said, owners consistently say the effects are life-changing — including reports of reduced body pain, better sleep, and better mood after a week of daily use. The product’s 4.4-star consensus across nearly a thousand owners makes it the safest bet for a first-time buyer who wants proven results without guessing.
What wins people over
- Loyal following of repeat buyers — many on their second or third bottle
- No taste, no smell, easy to add to daily routine
- Reported effects include better focus, creativity, and vivid dreams
The real trade-off
- 20 ppm concentration means you may need a larger serving than higher-ppm options
- Dosage instructions may be conservative; some owners increase to 2 tablespoons daily
Who this speaks to: First-time colloidal gold buyers and anyone who values a brand with a long, proven track record. This is the “start here” bottle.
Think twice if: You want maximum potency per drop without drinking a bigger volume each day — a higher ppm product like I Am Joy’s 100 ppm delivers more gold per milliliter.
2. Colloidal Gold Liquid by Nutrinoche – 8 oz – 30 ppm
The nano-crystalline formula that owners say feels “ethereal” under the tongue and works on just two doses per week.
Nutrinoche takes a different approach with a 30 ppm concentration using crystalline nano gold particles in pure vapor-distilled water. The brand claims it is 99.99% pure with no fillers, additives, salts, or proteins. What stands out in the feedback is that some users find it strong enough to take only twice a week, holding it under the tongue for absorption. The liquid is tasteless, according to many, and people report it provides more energy without feeling jittery. The bottle is 8 oz, and the package dimensions are 5.47 x 2.13 x 2.13 inches, weighing about 10.23 ounces — noticeably heavier than the compact I Am Joy bottle.
The most-discussed aspects are effectiveness and quality, with over twenty people praising its cognitive benefits. But some owners note the consistency can vary — some describe it as clear like water, while others note no color at all. This is a meaningful detail because true colloidal gold with ultra-fine particles should have a ruby-red tint. The fact that this one runs clear leads some to question whether it is truly a nanoparticle suspension or more of an ionic gold solution. The taste gets mixed feedback too, with some finding it neutral and others noting a faint aftertaste.
One reviewer noted an adjustment period: “I got a headache for about a week when I started using this, but I’m not sure if it’s because of this or if there’s some kind of die off.” That kind of honest report is worth knowing before your first dose. For the price, you get strong enough effects that some people stretch a bottle for months, making the per-dose cost quite low. If you are comfortable with a liquid that may appear clear rather than ruby-red, this is a solid mid-range option with good reviews behind it.
Smart value angle: The 30 ppm concentration in an 8 oz bottle works out to a very reasonable per-milligram cost compared to premium brands, especially if you can stick with a twice-weekly schedule.
Best for: Budget-conscious buyers who want a no-frills colloidal gold that still delivers noticeable mental clarity without needing a daily dose.
Consider skipping if: The clear appearance bothers you — if you want the classic ruby-red visual confirmation of nanoparticles, the I Am Joy or EnerGold options deliver that.
3. I Am Joy co. Liquid Colloidal Gold – 4 oz – 100 ppm
The 100-ppm ruby-red formula that many say restored dream recall after the very first dose.
I Am Joy co. steps firmly into high-potency territory with a 100 ppm concentration and an average gold nanoparticle size of less than 3 nanometers. That tiny particle size is key — small enough to produce a striking ruby-red color, which is the visual hallmark of a true nanoparticle suspension rather than ionic gold. The product uses only 99.99% pure 24K gold and medical-grade distilled water. The 4 oz glass bottle is compact at 0.79 x 2.36 x 3.54 inches, weighing 8.78 ounces — the smallest physical bottle in this roundup but packing the most gold weight per volume among the sub-100 ppm options.
The owner feedback is intense. The thing that wins people over most is the effectiveness for dream recall and mental clarity. One buyer’s experience sums it up well: “First dose restored dream recall after years; dreams fade post-wake but memory is astonishing.” Others report reduced joint pain, elimination of over-the-counter painkiller use, and a calm, focused energy that feels “hippy calm vibes in a bottle with subtle go go go energy.” The brand offers a risk-free promise — if you do not love it, they will refund the entire order.
The honest catch here is that some people do not enjoy the taste. Owners give the taste mixed reviews, with some calling it pleasant and neutral while others detect a metallic aftertaste. And the side effects category is mentioned by some — not as a widespread issue, but as something to be aware of if you are sensitive. The 100 ppm concentration means a few drops may suffice, unlike the larger volume needed with 20 ppm brands. However, the bottle is also the smallest by volume, so it will run out faster if your preferred dose turns out higher than expected. At 100 ppm in just 4 oz, you are trading volume for potency.
What makes it stand out
- Less than 3 nm average particle size — among the smallest in this comparison
- Ruby-red color confirms true nanoparticle suspension
- Risk-free refund promise from the manufacturer
The honest trade-offs
- Small 4 oz bottle may not last as long as 500 mL options if you take a full dropper daily
- Metallic taste noted by some owners
- Cold weather can affect the product; must be brought inside quickly after delivery
Reach for this if: You want high potency in a small package and dream recall is a primary goal. The ruby-red color gives you visual confirmation of quality.
Look elsewhere if: You prefer a larger volume bottle for the price and do not mind a lower ppm figure — MediGOLD gives you more total liquid for less per-ounce cost.
4. MesoGold 20 ppm Colloidal Gold – 250 mL
The particle-size specialist that uses its own MesoProcess to claim the highest surface area per drop.
MesoGold is the brand that argues we should care less about ppm and more about Particle Surface Area (PSA). They keep their concentration at 20 ppm but use a proprietary manufacturing method (the MesoProcess) to produce particles smaller than 3.2 nanometers on average with no ionic content. The result, according to the brand, is the highest bioavailability possible from a colloidal gold supplement. The 250 mL bottle (8.45 oz) is an intermediate size — bigger than the 4 oz premium bottles but smaller than the budget 32 oz options. The package dimensions are 10.24 x 6.81 x 2.68 inches.
The owner consensus revolves heavily around energy and effectiveness. The most-mentioned positive aspect is energy, followed closely by effectiveness. People report feeling a sustained, even energy flow throughout the day without the crash. One owner described it as “full energy on 5 hours sleep” with vivid dreams and sustained daytime energy. Others note it supports hand/eye coordination and a general feeling of well-being, which aligns with the brand’s claims. The product has no taste and is easy to take — most recommend holding it under the tongue for about 30 seconds before swallowing.
The main complaint isn’t about the product’s performance but its value for money. At 20 ppm in a 250 mL bottle, you are paying for the manufacturing process rather than raw gold content. Some owners find the cost high relative to volume, especially if they use a full tablespoon daily. A few also note that the color can vary, and some expected a redder solution. If you believe that particle surface area matters more than ppm, this is one of the few brands that openly publishes both metrics and backs the claim with engineering. If you want raw gold weight per dollar, look at the higher-ppm options instead.
The smart buyer take: MesoGold is the most technically transparent brand in this roundup. They tell you the particle size, the process, and the philosophy. This matters if you care about the science; it matters less if you just want the highest ppm number.
Perfect for: Analytical buyers who want to understand exactly what they are putting in their body and why smaller particles may be better than higher ppm.
Not for: Anyone who wants the highest gold concentration per dollar — the 20 ppm here is the same as MediGOLD but in a smaller bottle.
5. Colloidal Gold (Elixir) 240 ppm – 16 oz by Silver MTN Minerals
The 240-ppm giant that owners say looks pinker than other brands and delivers surprising potency per drop.
Silver MTN Minerals brings muscle with a 240 ppm concentration in a full 16 oz bottle — the highest ppm and largest volume of any option here. The brand claims a 15-year history of customer satisfaction and markets this as the most bio-active gold colloid supplement available. It is described as gluten-free, BPA-free, with no preservatives or additives, and safe for both children and pets. The manufacturer says the liquid is “fast acting” and digestion-friendly. The product’s weight is listed at 1 pound.
The feedback from regular users is strikingly consistent. Quality is praised most, followed by effectiveness. One long-time buyer calls this “one of the best on Amazon,” noting they keep coming back to it after trying other brands. Others say the liquid is “pinker than other 100ppm” and feels surprisingly potent, providing a sense of focus, inner peace, mood balance, and “nerve warmth.” Some users report deeper meditation states and what they describe as higher gamma EEG levels. The 240 ppm concentration is so strong that some users feel the bottle lasts a very long time even with daily use.
The honest trade-off is that the particle size is not published. You get a high ppm number, but without knowing the average nanometer size, it is impossible to compare bioavailability with MesoGold or I Am Joy. The brand says the product is “fast acting,” but there is no scientific breakdown of particle distribution. Some owners also note they bruise more easily while taking this product — a fairly uncommon side effect but mentioned by a few regular users. For the price, however, you get three times the gold weight of a 100 ppm bottle in the same volume, making this among the most cost-effective options for experienced users who know they respond well to gold supplementation.
What regulars love
- Highest ppm-to-dollar ratio among all products — 240 ppm in 16 oz
- Noticeably pinker visual color, indicating fine particle suspension
- Repeat owners mention it delivers focus and mood balance consistently
What to keep in mind
- Particle size not disclosed — you cannot compare bioavailability by spec sheet alone
- Some customers note easy bruising, though this is not universal
Reach for this if: You are an experienced colloidal gold user who knows your body responds well and wants the most gold per dollar in a single bottle.
Think twice if: You prefer transparent specs on particle size. Without that data, you are buying purely on ppm and trust.
6. Organa Pure Crystalline Liquid Gold – 32 oz – 30 ppm
The giant 32-ounce bottle of crystalline gold that one owner says improved arthritis finger curvature with a daily tablespoon.
Organa’s Pure Crystalline Liquid Gold offers a massive 32 oz for a moderate 30 ppm concentration. It is essentially a bulk-sized version of the Nutrinoche-style formulation — 99.99% crystalline nano gold particles in vapor-distilled water, no fillers, additives, salts, or proteins. The manufacturer uses a proprietary process to produce the particles, but does not publish the exact nanometer range. The package dimensions are 9 x 3.5 x 3.5 inches, weighing about 1 pound, so you get a lot of liquid volume for the price.
The few user reviews available paint a picture of a product that works but may be overpriced for its concentration. One buyer who takes 1 tablespoon daily says it improved the curvature of their arthritic fingers, calling it a “marvelous colloid.” Another describes it as tasteless with a calming brain effect similar to Ormus Gold. However, a critical review points out that the liquid was completely clear, like water, instead of the reddish-copper color expected from true colloidal gold. The same owner measured the ppm themselves and found between 25-28 ppm, which is close to the advertised 30 ppm, but the lack of ruby-red color raises the same question as with the Nutrinoche product: is this truly a nanoparticle suspension or primarily ionic gold?
At this size and price point, you are paying for volume rather than cutting-edge particle engineering. Organa does offer a product that appears to work for some people — specifically for calming the brain and providing subtle physical benefits — but the small review count and the clear-liquid concern make it a less confident purchase than the top picks. If you plan to use colloidal gold multiple times per day in larger servings, the value-size makes sense. If you want the visual confirmation of ruby-red nanoparticles, steer toward the I Am Joy or Silver MTN Minerals options.
Bottom line: This is the quantity-over-quality option. If you trust the brand and do not need visual confirmation, the price per ounce is among the lowest here. But the transparent liquid and limited user feedback are real caveats.
Best for: High-volume daily users who want the lowest cost per ounce and are less concerned about ruby-red visual confirmation of nanoparticle suspension.
Consider something else if: The clear appearance bothers you or you prefer a brand with more than 80 reviews to validate its formula at scale.
7. MesoGold 20 ppm Colloidal Gold – 500 mL
The double-sized MesoGold with the same 3.2nm particle promise, designed for long-term consistent use.
This is the bigger sibling of the 250 mL MesoGold, offering 500 mL (16.9 oz) at the same 20 ppm concentration with the same sub-3.2nm average particle size and the same exclusive MesoProcess manufacturing. The package dimensions are 8.82 x 3.07 x 2.76 inches, and it weighs 1.19 pounds — the heavier weight reflects the larger plastic bottle compared to the 250 mL version. Like the smaller bottle, it supports mental focus, concentration, hand-eye coordination, memory, and a general feeling of well-being.
The owner feedback focuses heavily on quality and health benefits, with seventeen people specifically praising the quality and fifteen noting positive health outcomes. One long-term user says it resolved depression and chronic fatigue, providing “abundant energy and happiness.” Another says their nails and hair have been positively impacted. The product is also noted as helping with more specific issues like colitis, arthritis, and tendonitis. Many describe it as the best colloidal gold they have tried, comparing it favorably to other brands they have tested over the years. The taste is described as like water with no bad aftertaste.
The recurring trade-off is the cost. Even loyal users admit the price is high, though most feel it is worth it for the confidence that comes with a trusted, consistent product. At 20 ppm in a 500 mL bottle, you are paying primarily for the particle engineering and brand trust rather than raw gold mass. If you compare by pure gold weight, a 100 ppm product like I Am Joy delivers five times as much gold per milliliter. But if you buy into the argument that smaller particles with higher surface area matter more than higher ppm, the double bottle is the most practical way to commit to a long-term regimen without running out quickly.
Why it earns the price
- Stated 3.2nm average particle size with no ionic content
- Proven consistency — Purest Colloids has manufactured since 2008
- Reviewers point out benefits for memory, mood, and even physical health
The real cost of quality
- Higher price per ounce of gold compared to high-ppm brands
- 20 ppm may require a larger daily serving volume
Ideal for: Anyone who wants the biggest bottle of MesoGold possible to reduce reordering frequency, trusting the particle-surface-area philosophy.
Skip if: You want the most gold for your dollar — the Silver MTN Minerals 240 ppm bottle gives you far more gold weight per serving.
8. EnerGold Ultraconcentrated 300-ppm Colloidal Gold
The 300-ppm triple-batch formula that owners use both orally and topically for healing and deep relaxation.
EnerGold is the most concentrated product in this roundup at a claimed 300 ppm, making it the true heavyweight. The manufacturer uses a unique triple-batch process: they make three separate batches with different particle size ranges (less than 2 nm, 2 to 12 nm, and 13 to over 24 nm) and then combine them into a single ultraconcentrated ruby-red suspension. The product also includes a trace amount of monoatomic gold and ORMUS for suspension stability. The bottle measures 7 x 3 x 3 inches and weighs 1.2 pounds, putting it in the premium-bottle category.
The positive feedback is extensive and intense. Quality and health benefits are the top mentioned aspects, with over fifty people praising each. The product is not just used orally — many owners spray it topically for wounds, infections, insect bites, arthritis pain, and skin issues. One report says a topical powder mixed with ointment eliminated severe knee arthritis inflammation pain in under 20 minutes. Another notes that it healed a dog’s skin lesion in two days. The mental clarity and meditation benefits are also heavily cited, with one experienced meditator saying the 300 ppm EnerGold was far more effective than the 20 ppm brands they previously used.
The honest limitation is stability. One detailed review reports that the deep-red liquid collapsed after three months — it turned clear and would not re-suspend, even with shaking. The reviewer still praised the quality but found that the ultraconcentrated formula could lose its suspension over time. The manufacturer addresses this on the label, but it is worth knowing if you plan to keep the bottle for extended use. Also, at this concentration level, dosing precision matters — too much can feel overwhelming, especially for first-time users. The price is the highest in the lineup, reflecting the extreme concentration level and the triple-batch manufacturing process.
what separates it
- 300 ppm concentration — the highest in the entire roundup
- Works for both oral use and topical applications (wounds, pain, skin)
- Triple-batch process with particles spanning less than 2 nm to over 24 nm
What to watch for
- Ultraconcentrated suspension can collapse over time (3 months reported)
- Very high price point; not for casual or first-time buyers
Reach for this if: You are an experienced user wanting the maximum possible concentration and want the flexibility to apply it topically on wounds, arthritis, or skin concerns.
Not recommended if: You are new to colloidal gold or prefer a lower-maintenance formula that keeps its suspension stability over months — go with MediGOLD or MesoGold instead.
Understanding the Specs
PPM (Parts Per Million)
This is the weight-based measurement of how much gold is suspended in the water. A 100 ppm product has five times the gold weight of a 20 ppm product per same volume. But this number alone can be misleading because a high-ppm product with larger particle clumps can have less bioavailable surface area than a lower-ppm product with tiny, well-dispersed nanoparticles. PPM is a helpful starting point, not the final judge. Use it to compare bottles of the same brand (e.g., 500 mL vs 250 mL) but be cautious cross-brand.
Particle Surface Area vs. Particle Size
Particle Surface Area (PSA) is the total gold surface available for interaction. Smaller particles mean exponentially more surface area per gram of gold. MesoGold bases its entire claim on this metric, arguing that high PSA equals high bioavailability. Particle size is measured in nanometers (nm), and anything under 10 nm is considered a fine nanoparticle. I Am Joy claims particles under 3 nm, MesoGold claims under 3.2 nm, and EnerGold’s triple-batch ranges from under 2 nm to over 24 nm. The lower the number, the finer the gold.
