Koi CBD Review

Our Rating: A. Innovate products and flavors with verified levels of CBD.
Koi CBD oil is a high-quality oil with guaranteed therapeutic concentrations of CBD. Their lab analyses check out in our research. Even though they include products like vape and gummies, their products actually contain therapeutic levels of CBD, a rarity in the industry. With cookie-cutter CBD companies, all franchises of one old hemp manufacturer, only the 25% oil and the concentrates actually have therapeutic levels of CBD. Not so with Koi. You can get enough CBD from grape vape or strawberry gummies with Koi. You don’t have to choose between fun or getting the CBD you need for stress and anxiety associated with various medical conditions. These products also contain the ‘entourage’ cannabinoids and terpenes like CBDV, CBG, limonene, and myrcene. We will focus on Koi Full Spectrum CBD oil but also go over information about the other products.
Figure 1.
CBD oil can be used under the tongue or added to foods. It may be dissolved in hemp oil or coconut oil. This adds healthy fatty acids and MCTs to the mix. Koi produces CBD tinctures, vapes, topicals, supplements, gummies, and even pet products. Koi provides CBD in various flavors. None of these products will make you high. They are meant as dietary supplements.

Koi sources its hemp from the San Luis Valley between Colorado and New Mexico. This is an arid, sunny region between the valley and the headwaters of the river called the Rio Grande. In this environment, hemp grows resilient, lush, and packed with cannabinoids and terpenes.

Advantages of Koi Hemp Oil

The advantage of Koi Hemp products is that they provide guaranteed therapeutic levels of CBD in innovative and delicious products. With most companies, you can either have therapeutic levels of CBD, or you can have cool products with cheap hemp oil in them and little CBD.

Koi Vape products actually deliver a therapeutic level of CBD via vape. Most vape products will not deliver you a therapeutic dose even if you vape all day long. Koi has done the math and has the lab analyses to prove it. Even their Tropical Gummies has 10 mg of CBD per gummy!  That is unheard of for CBD gummy candies, most of which just have hemp seed oil in them. The hemp seed oil has less than 25 parts per million of CBD.

One potential disadvantage of Koi is that they use a solvent-free extraction process for their CBD. We simply don’t know what this method is or if it produces a product of the caliber of supercritical CO2 extraction, or if it is worse or better. CO2 is the same stuff you breathe out, we know it’s fairly safe to use. Whatever method they use, we don’t know if it is more or less safe than CO2 extraction.

Lab Analyses

Koi lab analyses

Koi CBD uses the Confident Cannabis lab result reporting system to report lab results for each batch of the product tested by the CannaSafe Labs. Get it?  Confident Cannabis handles the lab reporting, CannaSafe laboratories do the testing. We will assume this is a third-party lab. And the lab results are very good, even for the vape products.

Q&A about Koi CBD

Can you use the vape juice sublingually?
How much do I take under the tongue?
Start with half a dropper.
What amount can I vape?
Try using half of your favorite vape juice and half Koi CBD. However, you can also use Koi CBD vape as is.
Do I need a specific vape pen?
Can I overdose on CBD?
There is no known overdose for CBD. As always, check the other ingredients in any product for which you may accidentally use more than recommended.
Does Koi vape have nicotine in it?
No, it does not.
There are small white specks in my vape juice. Is it safe?
Yes, this is normal.
How long does it last? How to store it?
Avoid extremes of heat and cold. CBD can become crystal again from heat or cold. Your vape juice can last one year under proper conditions. Don’t leave it in a hot car or put it in the refrigerator.
Will it affect my work?
Koi CBD products contain no CBD and will not affect your working ability. It will reduce pain and anxiety which may improve working ability.
Will CBD interact with my meds?
You should consult your doctor to eliminate drug interactions. There have not been many reports of adverse drug interactions with CBD.
Can I call in my order?
This is possible, but it’s best to order online.
Is the big number on the bottle the mg amount per serving?
No. That is the amount of CBD in the entire bottle. To find the mg amount, you need to look on the website, under the product name, for ‘CBD concentration’. Products are formulated to provide a therapeutic dose.
Is sublingual better or vape?
Sublingual for now. It is not truly known if vape delivers therapeutic levels of CBD.
Is CBD the same as marijuana?
CBD stands for cannabidiol. It is a non-psychoactive cannabinoid, one among as many as 125 identified cannabinoids in industrial hemp.
CBD is not pot, marijuana, hash, weed, or cannabis sativa. Koi’s CBD products contain no psychoactive THC, only small amounts of therapeutic THC, with large amounts of therapeutic CBD. Marijuana usually contains THC which is psychoactive, CBD does not.
What other cannabinoids are found in hemp oil?
Hemp oil may contain over 125 cannabinoids, including:

  • THC (tetrahydrocannabinol)
  • THCV (tetrahydrocannabivarin)
  • THCA (tetrahydrocannabinolic acid)
  • CBV (cannabivarin)
  • CBT (cannabicitran)
  • CBN (cannabinol)
  • CBDA (cannabidiolic acid)
  • CBDV (cannabidivarin)
  • CBE (cannabielsoin)
  • CBG (cannabigerol)
  • CBGM (cannabigerol monomethyl ether)
  • CBGV (cannabigerovarin)
  • CBL (cannabicyclol)
  • CBD (cannabidiol)
  • CBCV (cannabichromevarin)
  • CBC (cannabichromene)
Is it legal?
Yes, with some caveats. CBD and CBDa are legal in most states of the United States as long as it comes along with no more than 0.3% THC. CBD all by itself is pretty much legal everywhere. However, you could still run into legal problems if you have a cop or court which is hell-bent on charging people with violation of marijuana laws or even laws about where you can buy non-psychoactive hemp. This is rare but has happened on occasion.
CBD is legal in many countries, including:

  • Argentina,
  • Austria,
  • Belgium,
  • Belize,
  • Brazil,
  • Bulgaria,
  • Canada,
  • Chile,
  • China,
  • Colombia,
  • Costa Rica,
  • Croatia,
  • Cyprus,
  • The Czech Republic,
  • Denmark,

  • Poland,
  • Peru,
  • Paraguay,

  • Estonia.
Is hemp oil new?
Hemp has been around for at least 12,000 years.
How does CBD work?
CBD binds to receptors in the central nervous system including endocannabinoid receptors which help modulate the levels of monoamines, perceptions of pleasure and pain, and mood.
Is CBD psychoactive? Will it make you high?
No, and no.
Does Koi provide 3rd party labs on their website?
Yes, and the labs confirm that the CBD hemp oil product contains therapeutic levels of CBD.
What’s the difference between CBD, hemp oil, and hemp extract?
CBD means cannabidiol. It is a single cannabinoid, the second most abundant in marijuana and the most abundant in low THC hemp. Hemp oil is hemp seed oil. It contains healthy fatty acids, but only very low levels of CBD. Hemp extract is hemp oil extracted from the whole plant, standardized for levels of CBD. Unscrupulous companies will try to confuse consumers, passing off hemp seed oil as CBD. Koi CBD is legit and upright with its CBD levels.


Grade:  A

Koi CBD oil and other Koi products seem to be very well made. They post lab results for each batch and list the CBD concentrations per bottle and per serving. This is unique among companies. Most companies leave you to do the math yourself so that you don’t find out you will have to vape 3 full bottles to get one sufficient dose of CBD. With Koi vape, a normal amount can get you a therapeutic amount of CBD. And they also have tasty flavors and great label designs. So, it seems they really did their homework, used their in house lab, then sent it to a 3rd party lab.

CBD oil disclaimers (please read, this is important):

General Medical Disclaimer

Leaf Expert and its employees and partners do not represent the medical establishment and our information is not a replacement for your doctor’s advice.

Food and Drug Administration Disclaimer

The use of CBD products with the exception of Epidiolex and Sativex has not been evaluated or approved by the FDA.  These statements have not been evaluated by the Food and Drug Administration. These products are not intended to diagnose, treat, cure, or prevent any disease.

Drug Screening Disclaimer

While most CBD products claim to have little to no THC, it is theoretically possible to fail a drug test for THC. This can happen because some CBD products have been tested to have far more THC than represented on the label. Also, CBD is similar in structure to THC.

About CBD and CBD-A

How it Works (scientific research)

Koi’s products have cannabidiol as the main active ingredient. Cannabidiol is known to have many mechanisms of action. We list the receptors in the central nervous system which cannabidiol binds to below. These include cannabinoid receptors, serotonin receptors, and orphan receptors which are related to cannabinoid receptors by their structure. CBD also modulates opioid receptors by which it affects pain perception. These are not the only receptors cannabidiol may bind to or effect.

Cannabidiolic acid (CBDa) have been shown to have the following effects:

  • Fighting nausea (Rock, Limebeer, & Parker, Effect of combined doses of Δ 9 -tetrahydrocannabinol (THC) and cannabidiol acid (CBDA) on acute and anticipatory nausea using rat (Sprague- Dawley) models of conditioned gaping, 2015)
  • Breast Cancer growth inhibitor (Takeda, et al., 2012)
  • Anxiety fighter (Pertwee, et al., 2018)
  • Vomiting fighter (Bolognini, et al., 2013)
  • Depression fighter (Hen-Shoval, et al., 2018)
  • Diarrhea fighter (Cluny, et al., 2011)
  • Studied for inflammatory pain (Rock, Limebeer, & Parker, Effect of cannabidiolic acid and ∆9-tetrahydrocannabinol on carrageenan-induced hyperalgesia and edema in a rodent model of inflammatory pain., 2018)

Cannabidiol (CBD) has been shown to have the following health benefits:

  • Anti-cancer (Massi, Solinas, Cinquina, & Parolaro, 2013).
  • Anti-infarction (Hayakawa, et al., 2004).
  • Anti-psychotic (Iseger, Bossong, & Bossong, 2015).
  • Anti-seizure activity, known about in 1973 (Izquierdo, Orsingher, & Berardi, 1973).
  • Attenuates the adverse effects of THC (Henquet & Kuepper, 2010).
  • Can fight memory loss caused by marijuana THC(Morgan, Schafer, Freeman, & Curran, 2010). This means that medical marijuana should be enriched with extra cannabidiol to avoid memory loss and psychotic effects
  • Fights cerebral infarction by modulating serotonin (Mishima, et al., 2005).
  • Fights migration of cancer cells (Kapoor, 2013).
  • Fights myocardial ischemia-reperfusion injury (Durst, et al., 2007).
  • Inhibiting angiogenesis feeds cancers (Solinas, et al., 2012).
  • May fight autoimmune diabetes (Weiss, et al., Cannabidiol arrests the onset of autoimmune diabetes in NOD mice, 2008)
  • May fight colon cancer (Aviello, et al., 2012).
  • May fight neurodegeneration (Iuvone, Esposito, Filippis, Scuderi, & Steardo, 2009).
  • May help in colitis (Borrelli, et al., 2009).
  • May reduce immune system inflammatory responses (Kozela, et al., 2010).
  • Modulates sleep (Murillo-Rodríguez, Millán-Aldaco, Palomero-Rivero, Mechoulam, & Drucker-Colín, 2006).
  • Neuroprotective (Hampson, Grimaldi, Axelrod, & Wink, 1998).
  • Prevents diabetes (Weiss, et al., Cannabidiol lowers the incidence of diabetes in non-obese diabetic mice, 2006)
  • Reduces anxiety in the right doses (Fusar-Poli, et al., 2009).
  • Vasorelaxation (Stanley, Hind, Tufarelli, & O’Sullivan, 2015).
  • Wakefulness-promoting, modulation of circadian rhythms (Murillo-Rodríguez, et al., 2014).

Cannabidiol and cannabidiolic acid work by binding to various receptor targets throughout the central nervous system and the rest of the body. Acting at these receptor sites, it exerts influence on the metabolism of various neurotransmitter systems. It seems like ‘snake oil’ that one compound can have all the beneficial effects listed above; however, cannabinoid receptors exist throughout the nervous system and it is known that such a ubiquitous receptor must be involved in nearly everything the nervous system does, just like serotonin and dopamine receptors. Dopamine affects pleasure, but also pain. Anxiety and also relaxation. Heart contraction and blood pressure. All of these systems are integrated so cannabinoid receptors will indeed have effects on all of these systems and exogenous cannabinoids from plants can definitely have therapeutic effects that are extensive.

Mechanisms of action of CBD

  1. CB1 receptor agonist
  2. CB2 receptor agonist
  3. Glitazone receptor agonist
  4. GPR12 (inverse agonist)
  5. GPR3 (inverse agonist)
  6. GPR55 (antagonist) receptors
  7. GPR6 (inverse agonist)
  8. Inhibitor of fatty acid amide hydrolase, increasing levels of endogenous cannabinoids
  9. Serotonin 5-HT1A receptor partial agonist
  10. An allosteric modulator of mu and sigma opioid receptors (Kathmann, Flau, Redmer, Tränkle, & Schlicker, 2006)

The action of CBD and CBDa produces anti-inflammatory, anti-pain, and anti-seizure effects which can help relieve stress in a range of discomforting conditions.

Does CBD have any side effects?

CBD is unlikely to have many side effects under 300 mg daily. Above that dosage, one should consult a doctor.

Before we look at the side effects, let’s look at the safety. Consider these facts:

CBD Safety facts

  1. Does not induce changes in food intake
  2. Does not induce catalepsy
  3. CBD is non-toxic
  4. Does not affect physiological parameters such as:
    • Heart rate
    • Blood pressure
    • Body temperature
  5. Does not affect gastrointestinal movement
  6. Does not alter the psychomotor function
  7. It does not alter psychological functions.
  8. Chronic use and high doses up to 1,500 mg/day of CBD are reportedly well tolerated in humans.

(Bergamaschi, Queiroz, Zuardi, & Crippa, 2011)
Now, here are the side effects which have been reported:

Possible Negative Side Effects of CBD

  1. Tiredness
  2. Inhibition of hepatic drug metabolism (possible drug interactions)
  3. Decreased fertilization capacity
  4. Decreased activities of p-glycoprotein and other drug transporters
  5. Alterations of in vitro cell viability
  6. Sleepiness
  7. Poor quality sleep
  8. Insomnia
  9. Diarrhea
  10. Decreased appetite
  11. Changes in appetite

In general, CBD is safe and well-tolerated. Doses above 300 mg should have a doctor’s monitoring. Your doctor should manage drug interactions.
