CBG Dosage Guide
Summarize

A beginner taking CBD should start with a low daily dose to allow time to assess the CBG effects and work up to higher doses. A broadly recommended CBG dosage for beginners is 10-25 mg per day, depending on your weight. The doses can be divided into multiple doses throughout the day.
The following is a general CBG dosage guide; however, everyone’s journey is unique. The low-strength dosage is primarily intended for beginners. Most people will likely take a higher dosage once they determine that CBG addresses their wellness issue without side effects. For ease of calculation, dose amounts are rounded up or down to provide a closer match to the CBG amount in products.
CBG Dosage Recommendations by Weight
Weight Range | Low or Beginner Dose | Sustaining Dose |
---|---|---|
100–120 lbs | 10 mg | 30 mg |
121–140 lbs | 15 mg | 45 mg |
141–160 lbs | 20 mg | 60 mg |
161–180 lbs | 30 mg | 90 mg |
181–200 lbs | 40 mg | 120 mg |
201–220 lbs | 45 mg | 135 mg |
221–240 lbs | 50 mg | 150 mg |
Factors That Affect Your CBG Dosage
Several factors influence the optimal CBG dosage.
➥ Body Weight
Weight does impact the best CBG dose. The more you weigh, the more CBG is required to produce the ideal effects.
➥ Metabolism
Each person has a unique metabolism, and metabolism and liver function influence how cannabinoids are processed. Related to metabolism is the age factor. As people age, their metabolism typically slows, and research indicates that the functioning of the endocannabinoid system also decreases with age.

➥ Tolerance for Cannabinoids
Some people who regularly take cannabinoids may develop a tolerance. There is evidence that endocannabinoid system receptors become desensitized and downregulated, resulting in a reduction in the biochemical process. If you have been using cannabinoids like CBD and THC for a while, it may take a higher amount of CBG than would typically be needed to experience the effects. Another option is to take a cannabis tolerance break and allow the ECS system to restore sensitivity before taking CBG.
➥ Symptoms
The CBD dosage that works best also depends on why you are taking CBG and the severity of the symptoms you are trying to overcome. If you start with a low dose, you can adjust the amount upward or downward after a week or 10 days, based on whether your symptoms improve or require a higher dosage.
➥ Reasons for Taking CBG
People choose to take CBG for various reasons, and these reasons influence the ideal CBG dosage. Different research projects have found that CBG may act as an antibacterial, neuroprotective, and energy-boosting agent. Studies are finding that CBG may improve focus by reducing cortisol levels. There is also significant anecdotal evidence that CBG improves sleep. If you are taking CBG for better focus, you would take a lower dose than if you are taking it to promote sleep.
CBG Dosage Guide for Focus
Since CBG is not an FDA-regulated product, there are no official recommended dosage amounts. However, there is enough research and anecdotal evidence to suggest the following general guidelines as an example.
Assume a person is a beginner and weighs 130 pounds. She wants to improve her focus, so she decides to take CBG. She starts with 15 mg of CBG per body weight. However, to maintain focus throughout the day, she decides to take 10 mg in the morning and 5 mg midday for a week. After a week, she determined that CBG does help with focus and memory. She begins taking the sustaining dosage of 45 mg and splits it into three doses, taking 15 mg in the morning for an energy and focus boost, then 15 mg early in the afternoon, and 15 mg in the late afternoon.

A CBG Dosage Guide for Relief
If an individual wants to try CBG to see if it helps alleviate discomfort, the dosage guide would differ from the CBG dosage guide for focus. Starting with the sustaining dosage may be more effective than starting with the beginning dosage. CBG has a strong affinity for CB2 receptors within the endocannabinoid system, which plays a role in supporting immune function and maintaining overall physiological balance.
For example, if you weigh 150 pounds, take 60 mg per day, but do not take it all at once. Take a one-third dose three times daily, or 20 mg with each dose.
CBG Dosage by Product Type
You have options for taking CBG dosage because it is available in various product forms.
CBG oil
CBG oil comes in a bottle with a dropper. The ideal way to take a CBG tincture dosage is sublingually. You would hold the drops under the tongue for about 60 seconds. The label or Certificate of Analysis (COA) will indicate the number of milligrams of each cannabinoid, including CBG, in a dose. A CBG oil product will contain other cannabinoids when it is a full spectrum or broad spectrum CBG oil.
For example, a full spectrum CBG oil contains 1200 mg of CBG. Each serving is one milliliter. The COA reports the serving delivers 20.617 mg/mL of CBG, 6.451 mg/mL of CBN, 3.090 mg/mL of CBD, and small amounts of other cannabinoids. One serving delivers 20 mg of CBG. If you want to take 40 mg, you would double the serving.
In another example, a bottle containing 900 mg of cannabinoids, such as CBD, CBC, CBG, and CBN, may indicate a serving size of 10 drops. The 10 drops contain 7.5 mg of CBG per serving. To take 20 mg of CBD, you would take 20 drops of the CBD oil. You can take a quarter, half, three-quarters, or full dropper of CBG oil.
CBG gummies
CBG gummies contain a pre-measured amount of CBG. Most CBG gummies have a range of 5-30 mg of CBG per gummy. If the product has 5 mg of CBG per gummy, and you want to take 10 mg, then a CBG dose would be two gummies.
CBG capsules
Like CBG gummies, each CBG capsule contains a pre-measured amount of CBG. The capsules usually contain 5-30 mg of CBG each. It is essential to purchase CBG capsules that match your desired CBG dosage. Unlike CBG oil and CBG capsules, you cannot take half a serving. You can only take more capsules.
CBG isolate
CBG isolate is a pure form of CBG, available in crystal or powder form, which can be mixed into foods or beverages. The CBG isolate dose will contain as much CBG as you want to take per serving.
Tips for Successfully Following a CBG Dosage Plan
Like any medication you take, it is essential to pay attention to the effects felt. The following are some additional suggestions to help you have a successful experience by taking CBG.
✅ There is always the possibility of experiencing side effects from taking CBG. They include a dry mouth and headache. Some people have reported feeling drowsy, fatigued, or dizzy. If you experience these symptoms, it may be that your CBG dosage is too high, and you should consider reducing it.
✅ Though people start with 5-10 mg per day, a safe CBG dosage for a beginner is 15-20 mg per day, which can be divided among multiple doses. Follow the suggested CBG dosage amount on the product’s label as a beginner.
✅ After determining that the beginning CBG dose is well tolerated, experiment with various doses.
✅ Learn about dosage amounts, the COA, calculating a dosage amount, etc. Being an informed consumer is important.
✅If a beginner, keeping a journal of dosages taken each day and a description of the effects felt helps determine the ideal amount.
Since there is minimal research, it’s a good idea to start slow. Also, consult with your doctor, especially if you are taking medications.
