Does CBD Make You Tired?

Meredith Farrow, founder of Clean Remedies, says:

"Millions of people use CBD for sleep. Whether it will make you tired depends on several factors, including the specific product and dosage you take."

Talk to different people about CBD, and you might get seemingly conflicting reports. Many people take CBD recreationally and experience uplifting effects. But many others find CBD to be relaxing and find that it makes them feel tired.

So does CBD make you tired or not?

The short answer is yes. Some people do find that CBD causes drowsiness. That's why millions take it for sleep.

The longer answer is a little more complicated. Whether CBD will make you feel tired depends on a number of factors, including the product itself, your individual body chemistry, the dosage, and more.

How CBD Works

CBD, or cannabidiol, is a compound produced by the cannabis plant and hemp plant. It's a cannabinoid.

CBD is non-psychoactive, which means it doesn't have psychoactive properties. It can't get you high.

However, as a cannabinoid, it does interact with cannabinoid receptors in your body. These receptors are part of your body's endocannabinoid system, which interacts with many important bodily functions. That includes mood and sleep.

Why Is CBD Used for Sleep?

CBD is widely used for sleep. Over 42% of CBD users take it for sleep, and sleep is one of the most common reasons people give for trying and using CBD.¹

CBD is thought to help with sleep for a few reasons. We already mentioned how it interacts with the endocannabinoid system, which itself interacts with sleep. CBD is also believed to influence the activity of certain neurotransmitters, like adenosine, which affect sensations of sleepiness and alertness.²

Many people also use CBD for stress. Research shows it can promote relaxation.³ As you might know, stress is a common reason people can't sleep. By promoting relaxation, CBD might indirectly help with sleep, too.

Research suggests CBD can support sleep in a few other ways, too.

Multiple studies have found that CBD can enhance sleep quality. In one study, participants took CBD every day for two months. They reported significant improvements in sleep quality.⁴ Participants in a separate study also said that their CBD use made them feel healthier overall.⁵

Quality is just one part of the story. How long you sleep matters, too. Research suggests CBD can enhance sleep length.⁶

For many people, it's the process of getting to sleep that's the issue. One systematic review concluded that CBD could help with insomnia.⁷

Things to Consider

Before you jump into taking CBD for sleep, or for any other reason, there are a few important things to note.

Type of CBD

The kind of CBD product you take can play a big role in how you feel. For example, some CBD products contain other compounds, including sleep-supporting ingredients like GABA. Others don't.

Some CBD products are made from full-spectrum hemp extract. Full-spectrum means the extract contains all of the compounds naturally produced by the hemp plant. That includes THC.

The levels of THC, by law, should be small enough for the product as a whole to not cause any psychoactive effects. So why keep it in there? Well, the presence of THC is believed to make CBD even more effective. It's a phenomenon called the entourage effect.

However, those tiny amounts of THC can cause a positive drug test. If you prefer a THC-free product, go for broad-spectrum CBD.

Dosage

The amount of CBD you take also plays a role. Generally, lower doses are thought to be more likely to promote alertness and focus. Higher doses, on the other hand, are believed to be more likely to make you feel sleepy.

It's usually a good idea to follow the dosage instructions provided with your product. They should give you a sense of how much you should take for your desired effects.

Research has shown that CBD is quite well-tolerated, including in the long-term. One study found that 300mg of CBD could be taken every day for up to six months. Other research found that participants tolerated taking up to 1.5g of CBD per day.⁸

Other Medications

CBD is processed in your liver by enzymes. It may interact with other medications, including those that induce drowsiness. If you're unsure, check with your doctor.

Timing

When you take your CBD might play a role. Some people find that taking their CBD earlier in the day minimizes potential feelings of tiredness.

On the other hand, if you're taking CBD to address poor sleep, it's usually recommended to take it close to bedtime.

Product Quality

The quality of your CBD product matters more than you might think. Low-quality products might contain less CBD than you'd expect, or other compounds you might not want.

One study found that 26% of CBD products contain less CBD than labeled.⁹ Another study found that some CBD products were contaminated with heavy metals like lead.¹⁰

Reputable manufacturers should submit their CBD products for testing in a third-party laboratory.

Where to Get High-Quality CBD Products

Clean Remedies uses a third-party lab to test all of our products for potency and purity. You can see the results of these tests by viewing the certificate of analysis attached to each product.

If you want to take CBD for sleep, consider our Sleep & Soothe CBD Gummies. Each of these melatonin-free gummies contains 20mg of full-spectrum hemp extract, plus GABA, L-Theanine, and CBN. Together, these ingredients are intended to calm both mind and body, guiding you into restorative sleep.

"I take two gummies on nights that I'm really stressed out," says Clean Remedies founder Meredith Farrow, "and one gummy on other nights."

If you prefer a zero-THC option, try our Relax & Calm CBD Gummies. They're made from broad-spectrum hemp extract, and each gummy has 10mg of CBD. They're a ritual of ease and balance designed to help you find your calm whenever you need it. And for an only-THC option, we have 10mg THC Gummies.

Edibles are a popular way to take CBD. So is CBD oil. One benefit of CBD oil is its versatility. You can add it to a steaming cup of nighttime tea, mix it in with your favorite evening snack, or take it straight from the bottle. When you place it under your tongue, it absorbs faster than edibles do.

Clean Remedies offers both full-spectrum and broad-spectrum CBD oils.

Conclusion

CBD can make you feel tired. Many people use it for sleep. However, it won't necessarily make you feel tired, and it can actually make you feel alert. Factors like dosage, when you take it, and what other ingredients are included in your CBD product can affect this.
