CBD Oil Dosage

The ideal CBD oil dosage is an elusive thing that depends on multiple factors. Your body weight, metabolism, and individual symptoms all play a role in how much CBD you should take.

Alongside these elements, the quality and concentration of the CBD product you’re using will make a big difference to your dosage.

Variables aside, most people start with a CBD oil dosage of somewhere between 20 – 40 mg per day.

That number may be slightly lower for the highly sensitive or those who weigh less than 100 pounds, or more for those above 200 lbs. 

After a week of steady supplementation, many choose to begin increasing their dose. We recommend experimenting with 5 mg intervals until you no longer feel any extra benefit.

Keep in mind that CBD products are infusions, so 1 ml of CBD oil does not contain 1 mg of CBD. The same goes for edibles and CBD topicals. Read the label of your chosen product to see how much CBD is infused by weight.

CBD Dosage Chart

Here’s a simple CBD dosage chart that combines user body weight with condition severity. While the perfect dosage requires knowing more about individual factors, this is a good starting point for your CBD journey:

Use the table above to gauge a general dosage for your body weight and condition. This will give you a benchmark from which to begin experimenting with a personal dose.

Once you have an amount in mind, take a look at the concentration of your CBD oil or edible to find out how much to take. Some products come in simple single servings, while others require you to calculate the dosage.

How To Calculate CBD Dosage

1.  On average, a drop of CBD oil from a tincture is around 0.05 ml in size. Divide the total size of the CBD bottle by this number to work out how many drops a bottle contains.

2.  Read the label of your CBD oil to find out its concentration. Divide the concentration by the number of drops in the bottle to find out how much CBD is in each drop.

 

3.  Once you know how much CBD is in each drop, it’s easy to work out how many drops to take for your needs.

How To Take CBD Oil

CBD oil is a versatile supplement that can be consumed in several ways. Most experts recommend dropping the oil under your tongue, in what’s known as sublingual application.

Sublingual application allows much of the CBD to be absorbed directly into the blood vessels in the mouth. This means less is lost to the metabolic or digestive processes that occur when CBD enters the body through the lungs or the stomach.

 

Other popular ways to use CBD include adding drops to food or massaging it directly into the skin.

CBD Dosage For Edibles

Many CBD and cannabis users report that edible CBD has a delayed and less predictable effect than CBD that’s inhaled or consumed sublingually. Be sure to give your dose 3 – 4 hours to take effect before making any judgments or taking more. 

 

Again, keep in mind that 1 mg of an edible does not equal 1 mg of CBD. Always read labels carefully to check for concentrations and other ingredients and allergens.

CBD Dosage For Edibles

Here’s what CBD researchers and consumers say about CBD dosages for specific conditions.

Factors Affecting CBD Dosage

Several factors can affect your CBD dosage, the biggest being the reason you’re taking CBD in the first place

.

Those in significant discomfort or suffering from severe neurological conditions often benefit from much higher doses of CBD than those supplementing for general anxiety or daily wellbeing.

Bodyweight is any factor that significantly affects how CBD works, which is why we recommended calculating dosage by the pound.

Those on prescription medications may find that higher CBD doses cause drowsiness.

Previous exposure to cannabis and consumption of alcohol and other sedatives will also affect dosages.

 

Also, long-term CBD use itself is likely to result in a build-up of tolerance, meaning that dosages will need to be raised periodically.

CBD Dosage For Sleep

Evidence suggests that CBD dosages for sleep are highly individual. However, many users report success when taking a moderate-to-high dose in comparison to their usual amount

.

Researchers working in 2019 studied the effects of a 25 mg daily dose of CBD on sleep quality in 72 subjects, over half of whom also experienced anxiety. In the study, just over two-thirds of participants reported improvements to sleep.

CBD Dosage For Pain

Depending on the intensity of pain and discomfort, a good starting dose of CBD oil is between 20 – 50 mg per day. But as the studies show, this amount can be significantly increased in severe cases.

CBD dosage for Joint pain and arthritis

For inflamed joints, The Arthritis Foundation recommends starting with only a few mg of CBD, taken twice per day. Dosages should then be increased by small increments on a weekly basis.

The Foundation also highlights the importance of keeping doses regular in order to “maintain a stable level of CBD in the blood.”

CBD dosage for Neuropathy pain

When researchers conducted a small study on the effects of CBD on neuropathy pain, they found that participants reported a statistically significant reduction in symptoms when compared to a placebo.

The dosage used in the study was a CBD product that contained 250 mg of CBD.

CBD Dosage For Chronic Conditions

CBD isn’t a cure for chronic conditions, but many users have found relief from the daily discomfort and frustration that comes from an ongoing illness.

CBD dosage for IBS and Crohn’s disease

CBD’s credibility as a supplement for IBS and Crohn’s comes mostly from cannabis’s anti-inflammatory properties.

When researchers gave 30 participants with Chron’s a regular dose of cannabis (not CBD extract), they found that 21 were able to reduce their need for other medications and surgeries. 

CBD dosage for High Blood pressure (hypertension)

There’s growing evidence that CBD could play a role in helping to reduce hypertension and its symptoms.

In 2017, research from the UK found that a single, 600 mg dose of CBD lowered both resting blood pressure and stress-related blood pressure increases in males—though the study stopped short of recommending CBD for the treatment of cardiovascular disorders.

CBD dosage for epilepsy

Multiple studies over the past decade have confirmed CBD’s status as an anticonvulsant, leading to its use in clinical practice—a rarity for CBD.

A CBD dosage schedule for seizures should be developed with your health care provider. Often, dosages begin at between 2.5 and 5 mg of CBDper kg of body weight and are reviewed and incrementally increased on a weekly basis, according to Medscape. 

CBD dosage for cancer

Very early research suggests that CBD may possess some direct anti-tumor properties. Studies such as this one from 2019 have observed CBD’s ability to block tumor cell activity.

More generally, CBD—as well as medical cannabis—may be a good option for anyone experiencing inflammatory symptoms as the result of cancer or cancer treatments. This includes nausea, headaches, muscle pain, and gastrointestinal irritation.

Dosage for these symptoms is highly individual depending upon their severity.

For Canadians with cancer, Sativex, a CBD/THC oral spray to treat pain and discomfort may be available by prescription. Talk to your healthcare provider for more information.

CBD Dosage For Anxiety

For mild-to-moderate anxiety or nervousness, a good starting dose of CBD oil is between 15 and 35 mg per day. As with all uses for CBD, but especially anxiety, users can expect more successful effects from a consistent dosage that allows CBD to build up in the bloodstream.

For some, a much higher CBD dose has been shown to be effective in reducing anxiety symptoms. In a review of studies published in 2015, the authors found that trials using significant doses ranging from 300 to 600 mg were most effective.

 

The review concludes that CBD has the potential to reduce anxiety in patients with SAD, in the treatment of PTSD, and for “enhancing cognitive behavioural therapy.”

CBD Dosage For Dogs  🐶

Dogs are vulnerable to several common inflammatory conditions, including osteoarthritis and canine anxiety. As a result, they can also benefit greatly from CBD supplementation.

 

** Always give dogs and other animals pet-friendly CBD products designed for non-human use. **

How To Calculate CBD Dosage For Dogs

There are three things to keep in mind when developing a CBD dosage for dogs:

  1. The dogs’ condition

  2. The dogs’ body weight

  3. CBD product concentration​

 

Using these factors, owners can give their dogs CBD with a starting dose of 0.2 mg per lb of their pets’ body weight.

Just like humans, dogs will benefit from a personalized dosage, and owners should experiment with what works for their pup. Increases of doses up to 0.7 mg per lb are generally tolerated well.

As with traditional medications, dogs can also build a tolerance to CBD, so dosages may need to be slowly raised over time to retain their effect.

Talk to your dogs’ healthcare provider to develop a specific dosage schedule for their individual needs.
