What Are CBD Suppositories?

The growing list of CBD product forms now includes CBD suppositories. Not often discussed, they are the ideal product form for people who want to bypass the digestive system, have trouble swallowing, or want higher bioavailability. CBD and other ingredients are rapidly and efficiently delivered to the system.

What are CBD Suppositories?

CBD suppositories are solid and shaped like a capsule for easy insertion. They are formulated so that body heat melts the solid natural fat capsule when inserted into the vagina or rectum. CBD and other cannabinoids enter the bloodstream after absorption through the mucous membranes in the body.

One of the advantages of CBD suppositories is that they bypass the digestive system. The cannabinoids do not have to undergo first-pass metabolism in the liver. The metabolic process takes place in the liver and reduces the amount of CBD that reaches the bloodstream. Bypassing this process increases systemic bioavailability, meaning more CBD is absorbed and at a faster rate.

The bioavailability of suppositories is higher than that of oral ingestion. Rectal CBD suppositories can have a bioavailability of 50% or even higher. CBD taken orally typically has a bioavailability of no more than 20%.

Why Do People Look for CBD Suppositories?

There are several reasons that people decide to learn about CBD suppositories.

1. Targeted and localized relief

Consumers say they choose suppositories because they provide targeted relief. The rectum and vagina have a complex set of blood vessels that enable CBD to enter the bloodstream quickly.

The colon is rich in cannabinoid receptors CB1 and CB2. These receptors have a role in regulating the movement of food during digestion. These receptors are also present in the woman’s pelvic area. Women using suppositories say that CBD helps reduce discomfort associated with menstruation and endometriosis. They are also chosen for the potential to help with vaginal lubrication and to reduce symptoms of menopause. A program evaluation found women reported significant improvement in menstrual cramps and other symptoms after using CBD suppositories and other forms of CBD products. Those using suppositories said they felt relief within 60 minutes, and it lasted for two to four hours.

It is important to note that a lot more research is needed. These are not medical or health claims. Most evidence related to the use of CBD suppositories is anecdotal evidence.

2. A non-oral CBD format

Many people have trouble swallowing, dislike taking CBD sublingually, or are unable to find a flavor they like. Others have digestive issues, so avoid eating or drinking anything that might cause problems. CBD suppositories are a good alternative in these cases.

3. Faster absorption

Many factors influence the absorption rate of CBD and other cannabinoids. However, suppositories bypass the digestive process, which is likely to make more CBD available and at a faster absorption rate. The ingredients in CBD suppositories, including the carrier, have a major influence on bioavailability.

4. Discreet usage

CBD suppositories are very discreet. They are odorless, require no preparation, do not need assistive devices like a dropper, and can be easily carried wherever you go.

5. Avoiding the risk of THC effects

Full spectrum CBD contains THC, legally limited to 0.3%. Depending on sensitivity to THC’s psychoactive properties, there may be a risk of experiencing some effects when taking CBD oils and capsules. The risk of experiencing THC psychoactive effects from CBD suppositories is minimal.

What is Usually Inside a CBD Suppository?

The ingredients in CBD suppositories vary. The suppository will contain full spectrum, broad spectrum, or isolate CBD, along with any of the following ingredients.

• Natural or added concentrations of minor cannabinoids, such as CBC, CBG, CBN, etc.
• Carrier compound, i.e., cocoa butter, MCT oil, coconut oil, etc.
• Terpenes
• Flavonoids
• Botanical extracts
• Vitamins
• Plant-derived glycerides or fatty acids

How to Use CBD Suppositories Safely?

There are some general safety practices to follow.

• Review the ingredients closely. Check for potential allergens or any substance you may be sensitive to.
• Avoid products with essential oils if the suppository will be inserted into the vagina. Purchase CBD suppositories formulated for women.
• Only purchase CBD suppositories that have been lab-tested by an independent laboratory. A Certificate of Analysis (COA) should be easily accessible. It reports on cannabinoid levels and provides profiles of pesticides, microbes, mycotoxins and heavy metals.
• Always follow the directions the brand provides for use.
• Wash your hands before and after product use to avoid contamination.
• Follow the instructions for preparing the suppository for use.

There are also tips for ensuring you get the most benefit from the CBD suppository.

Insertion

Insert the CBD suppository past the sphincter muscle. If inserting vaginally, follow the brand’s instructions concerning depth. Usually, the recommendation is to insert the suppository as high as possible into the vagina. Applying a light amount of water to the suppository can make it easier to insert.

Allow time for the suppository to melt

After insertion, remain lying down or seated for 10-20 minutes. This gives the suppository time to melt. It also reduces the chance it will slip out of place.

Start with a low dose

CBD suppositories usually have higher CBD amounts, such as 50 to 100 mg per dose. Start with the lowest CBD dosage and assess your response. If you experience unwanted effects, stop using the suppository immediately.

Always check with your doctor before taking any CBD product. CBD does interact with some prescription medications, especially those metabolized in the liver.

Common Mistakes to Avoid

The following are common mistakes you want to avoid.

• Choosing products that do not have a COA

• Storing the suppositories where they are exposed to heat, causing them to soften
• Using more suppositories per day than recommended
• Using the highest CBD dosage as a beginner
• Thinking, CBD topicals, such as lotions and creams, can be used internally
• Failing to adhere to good hygiene practices
• Using products that have expired

FAQs

Specialized CBD Option

CBD suppositories are another option for taking CBD. They offer a good alternative when taking oral products is not the best option. By delivering CBD through the membranes in your body, the digestive process is bypassed. Research to date has found that CBD is absorbed more quickly and has higher bioavailability. More clinical studies are needed, but to date, research has found that suppositories are an effective means of administering compounds that support wellness.
