Why Your Body Wastes Most of the CBG You Pay For
Written by Marc Narrie, founder of Buddha Beans Coffee Co. and specialty coffee roaster since 2019. Buddha Beans has been infusing coffee with CBG since launch, making it one of the first CBG coffee brands in the US.
You're absorbing about 6% of that tincture
If you've been taking an oil-based CBG tincture or drinking oil-infused CBG coffee, here's something most brands won't tell you: your body throws away roughly 90-94% of the CBG before it reaches your bloodstream.
That's not a defect in the product. It's just how oil and water interact in your digestive system. And your digestive system is almost entirely water.
The oil problem, explained simply
CBG in its natural extracted form is an oil. When you swallow that oil, your body has to break it down before it can absorb the active compound. That process is slow and inefficient. Most of the CBG passes through your GI tract without ever making it into your bloodstream.
The pharmaceutical industry calls this "bioavailability," the percentage of a substance that actually reaches your systemic circulation. For oil-based cannabinoids taken orally, bioavailability sits around 6-10%. Some studies put it even lower.
So that 30mg dose on the label? Your body gets maybe 2-3mg of usable CBG. You paid for the whole bottle. You got a fraction of it.
What water soluble actually means
Water soluble CBG isn't a different cannabinoid. It's the same CBG molecule, processed through nano-emulsion technology to make it compatible with water.
The process breaks CBG oil into particles small enough to stay suspended in liquid rather than separating out. Think of it like the difference between dropping olive oil into water (it floats on top) versus stirring milk into coffee (it dissolves completely). Nano-emulsion makes CBG behave like the milk, not the olive oil.
Because the particles are small enough to dissolve, your body treats them more like a water-soluble nutrient than an oil it needs to metabolize. Absorption goes up 4-5x. That 30mg dose now delivers the equivalent of 120-150mg from a traditional oil product.
Why almost nobody does this for CBG
Nano-emulsion technology exists. It's used in pharmaceuticals, beverage companies, and some CBD products. But almost nobody applies it to CBG.
Two reasons. First, CBG is already more expensive than CBD because hemp contains so little of it (under 1% at harvest vs 15-20% for CBD). Adding nano-emulsion processing on top of already expensive raw material makes the economics harder.
Second, the formulation is genuinely difficult. You can't just run any cannabinoid through a generic emulsification process and expect it to work. Different molecules behave differently. CBG required its own formula, developed from scratch, tested and iterated until the stability and absorption numbers were right.
We spent over a year working with one of the top nano-emulsion labs in the industry to build our formula. We're currently the only company offering water soluble CBG. That's not marketing language. It's a fact you can verify by looking at what's on the market.
What the difference feels like
People who switch from oil-based CBG to water soluble consistently report the same things: faster onset, cleaner effects, more consistent results cup to cup or dose to dose.
The speed difference is the most obvious. Oil-based CBG can take 45-90 minutes to kick in because your body has to break it down first. Water soluble typically hits in 15-20 minutes. You notice it in your morning coffee rather than wondering if it's working two hours later.
The consistency matters too. Oil-based absorption varies depending on what you ate, how your stomach is doing that day, and a dozen other variables. Water soluble absorption is more predictable because it doesn't depend on your body's ability to process oil.
The math that matters
A typical oil-based 900mg CBG tincture delivers roughly 54-90mg of usable CBG over the life of the bottle (6-10% of 900mg). Our water soluble 900mg tincture delivers closer to 450mg of usable CBG (around 50% bioavailability based on nano-emulsion research). Same label. Five times the actual dose reaching your system.
That's not a marginal improvement. It's the difference between a product that works and one that mostly doesn't.

This is the problem our water-soluble CBG tincture is built around. How it works: the water-soluble CBG guide.
Our Black Label CBG Coffee and Colombia CBG Coffee use water-soluble CBG for maximum absorption in every cup. For standalone use, our Water-Soluble CBG Tincture comes in 300mg and 900mg sizes.

Frequently asked questions about CBG bioavailability
What is the bioavailability of CBG?
Oil-based CBG has an oral bioavailability of approximately 6-10%, meaning your body absorbs only 6-10% of the CBG you swallow. Water-soluble CBG created through nano-emulsion has significantly higher bioavailability, estimated at 4 to 5 times that of oil-based formulations, because the smaller particle size (under 100 nanometers) allows faster absorption in the gastrointestinal tract.
What is nano-emulsion CBG?
Nano-emulsion CBG is CBG oil that has been broken into particles smaller than 100 nanometers using high-pressure homogenization or ultrasonic processing. These tiny particles are small enough to be suspended in water, making the CBG "water-soluble." The pharmaceutical industry has used nano-emulsion technology for decades to improve the absorption of fat-soluble compounds.
How do you increase CBG absorption?
The most effective way to increase CBG absorption is to use a water-soluble (nano-emulsion) form rather than oil-based products. Taking oil-based CBG with fatty food can also improve absorption slightly, as fat aids in the digestion of oil-soluble compounds. Sublingual administration (holding oil under the tongue for 60-90 seconds) bypasses first-pass liver metabolism and improves absorption compared to swallowing directly.
Is water-soluble CBG worth the extra cost?
When adjusted for actual absorption, water-soluble CBG can be more cost-effective than oil-based CBG despite a higher sticker price. If oil-based CBG has 6% bioavailability and water-soluble has 25-30%, a 300mg water-soluble tincture delivers the equivalent absorbed dose of a 1,250-1,500mg oil-based product.
First-pass metabolism in the liver destroys 70 to 88 percent of orally consumed oil-based CBG before it reaches the bloodstream. A 30mg oil-based CBG dose delivers only 3.6 to 9mg of active compound to systemic circulation. Nanoemulsion water-soluble formats bypass much of this first-pass loss, delivering 6 to 9mg from the same 30mg dose, effectively doubling usable CBG per dollar spent.
CBG Bioavailability by Delivery Method
| Delivery Method | Bioavailability | Onset Time | CBG Absorbed from 30mg Dose | Best For |
|---|---|---|---|---|
| Oil-based tincture (swallowed) | 6 to 12% | 45 to 90 min | 1.8 to 3.6mg | Budget option, slow release |
| Oil-based tincture (sublingual hold) | 12 to 18% | 20 to 45 min | 3.6 to 5.4mg | Moderate absorption |

| Water-soluble CBG coffee | 18 to 25% | 30 to 60 min | 5.4 to 7.5mg | Daily routine integration |
| CBG capsule | 6 to 10% | 60 to 120 min | 1.8 to 3mg | Convenience, no taste |
| CBG topical | Local only (not systemic) | 15 to 45 min | N/A (skin absorption) | Targeted area application |
Water-soluble CBG, like the Buddha Beans CBG Water-Soluble Tincture, uses nanoemulsion to maximize the percentage of each milligram that reaches your bloodstream.
