In Switzerland, over 500,000 people use CBD regularly, according to the Federal Office of Public Health (FOPH, 2023). Yet despite the growing popularity of this natural molecule, finding the proper CBD dosage remains a complex and deeply personal matter.
CBD works primarily by modulating the endocannabinoid system (ECS)—a crucial physiological network that helps maintain balance in the body. According to Zou and Kumar (2018) in Cannabinoid Receptors and the Endocannabinoid System: Signaling and Function in the Central Nervous System (International Journal of Molecular Sciences), cannabidiol interacts indirectly with several receptors, which helps explain the highly individual nature of its effects.
Bruni et al. (2021), writing in Molecules, further confirm that factors like body weight, metabolism, age, overall health, and product concentration directly impact how effective your CBD daily dose is. That’s why there’s no one-size-fits-all approach to dosing.
Today, most researchers agree on a cautious and personalized strategy: “start low and go slow”—begin with small doses (5 to 10 mg daily), observe how your body responds, and gradually adjust. Millar et al. (2019), in their review A Systematic Review of Cannabidiol Dosing in Clinical Populations (British Journal of Clinical Pharmacology), emphasize that keeping a dosing journal remains the most effective way to find your optimal CBD dosage over time.

Why proper CBD dosing is crucial for your comfort and safety
Finding the correct CBD dosage isn’t just about saving money—it plays a key role in your well-being and how comfortable you feel throughout the day. Using too little may mean missing out on the expected effects, while too much can lead to unwanted sensations like drowsiness.
As highlighted by MacCallum and Russo (2018) in Practical considerations in medical cannabis administration and dosing (European Journal of Internal Medicine), the relationship between dosage and effect often follows a bell-shaped curve. The effects may be too subtle to notice at low levels, while excessive doses could reduce the desired impact or cause mild sedation.
The World Health Organization (WHO) confirmed in its 2018 CBD safety review that cannabidiol has an excellent safety profile. However, it also emphasized that a suitable dosage is essential for responsible use.
By adjusting your CBD daily dose to what your body truly needs, you can:
- Enjoy consistent effects over time
- Avoid drowsiness or discomfort linked to overdosing
- Make the most of your CBD products by using only what’s necessary
How CBD interacts with your body: the key role of the endocannabinoid system
CBD primarily influences your endocannabinoid system (ECS), a complex network of receptors distributed throughout the body that helps regulate numerous physiological functions such as mood, stress, sleep, and inflammation.
Unlike THC, which binds directly to CB1 and CB2 receptors, CBD interacts indirectly. According to Zou and Kumar (2018), CBD modulates receptor activity without activating it directly, which may explain the absence of intoxicating effects.
Beyond CB1 and CB2, CBD also affects other receptors, such as 5-HT1A (serotonin), TRPV1 (pain and temperature), and PPARγ (inflammation and metabolism). This broad interaction profile is one of the reasons why the effects of CBD can vary so much from one person to another.
By subtly adjusting the production and reuptake of natural endocannabinoids like anandamide, CBD contributes to internal balance, or homeostasis—laying the foundation for a more personalized approach to CBD dosing.
What factors influence your ideal CBD dose?
Determining the proper CBD dosage for your body is influenced by several key factors. Taylor et al. (2020), in An Analysis of Consumer Cannabidiol Usage Patterns and Perceptions (Journal of Clinical Pharmacology), found that daily usage can range from as little as 10 mg to over 800 mg, depending on the individual.
To identify your optimal CBD daily dose, you must consider five essential variables: body weight, symptom intensity, physiology, experience with CBD, and the product type. Let’s take a closer look at each of them.
1. Your body weight: an essential starting point for weight-based dosage
Your body weight is often a logical starting point for calculating your weight-based dosage. According to Bergamaschi et al. (2011) in Current Drug Safety, a standard range of 1–6 mg of CBD per 10 kg of body weight is generally recommended.
For instance, someone weighing 70 kg might start with 7 to 42 mg of CBD per day. This approach considers how cannabinoids are distributed in body fat and how that affects bioavailability and effectiveness.
2. Symptom severity and desired effect: tailoring your daily CBD dose
The intensity of your needs should also guide your choice of CBD daily dose. Larsen and Shahinas (2020), in their review Dosage, Efficacy and Safety of Cannabidiol Administration in Adults, identified three general levels of dosage:
- Mild: 5–15 mg per day
- Moderate: 15–45 mg per day
- High: 45–150 mg per day or more
For mild daily support, lower doses often suffice. Moderate to high doses might be necessary for more intense needs—constantly adjusting based on individual response.
3. Your physiology (metabolism, age, sensitivity) and dosage considerations
Your physiology plays a significant role in how you respond to CBD dosage. Stott et al. (2013), in a pharmacokinetic study (British Journal of Clinical Pharmacology), found that individuals with a fast metabolism may require higher or more frequent doses to feel an effect.
Sensitivity to cannabinoids also varies by genetics and age, affecting how the endocannabinoid system responds to external cannabinoids like CBD. This reinforces the importance of starting low and adjusting slowly based on your body’s reactions.
4. Your prior CBD experience (beginner or experienced)
Whether new to CBD or a seasoned user also impacts how you approach dosing. According to Taylor et al. (2018), regular users may develop a mild tolerance over time, which can slightly alter how much CBD they need to feel the same effects.
To reset your sensitivity, some experts recommend taking short “CBD breaks” of 3–5 days every few months. This allows your endocannabinoid system to recalibrate and may help enhance product effectiveness during future use.
5. CBD product type, administration method, and bioavailability
Not all CBD products are created equal. The method of use directly influences bioavailability or how much CBD reaches your bloodstream. Millar et al. (2018), in European Journal of Clinical Pharmacology, report significant differences between methods:
- Inhalation: 50–80% bioavailability
- Sublingual: up to 35%
- Oral (capsules or edibles): 4–20%
- Topical: 5–10%, with localized effects only
A higher bioavailability means you can achieve the same results with a lower CBD dose, making product format and concentration critical when building your personalized routine.
How much CBD (in mg) should you take daily?
Your ideal CBD dosage can vary significantly—from 5 to 150 mg per day—depending on your weight, goals, and personal sensitivity. In their review A Systematic Review on the Pharmacokinetics of Cannabidiol in Humans (British Journal of Clinical Pharmacology, 2019), Millar et al. found that most people settle around 10 to 80 mg daily.
According to the WHO (2018), CBD daily dose levels are generally well tolerated, even at high amounts. Still, the gradual approach remains essential to balance potential benefits with comfort and avoid unnecessary excess.
CBD starting amounts for beginners
If you’re new to CBD, the safest strategy is to begin with low-strength oil, around 5 to 10 mg per day—for the first week. Laczkovics et al. (2023), in Journal of Cannabis Research, confirmed this approach as effective and well-tolerated in most individuals.
Monitor how your body reacts, and consider keeping a journal. After five to seven days, increase your CBD dose by 5 mg if needed. For extra sensitivity, even a starting point of 2.5 mg may be more suitable.
General dosage chart by weight and symptom severity
The table below offers rough guidelines for choosing your CBD dosage based on both your body weight and how intense your needs are:
These recommendations are based on several sources, including Millar et al. (2019), Laczkovics et al. (2023), Sarris et al. (2022), and dosing frameworks from TGA (Australia) and the FDA (US).
Recommended dosages for everyday needs
Scientific studies suggest that adjusting your daily intake based on your personal goals may help you maximize the potential CBD benefits. While there’s no universal dose, data shows recurring patterns for anxiety, sleep, and pain that can guide your approach more effectively.
CBD for anxiety and stress management
Using CBD for anxiety may require slightly higher daily doses than general wellness support. Research by Sarris et al. (2022) observed notable effects with 25 to 40 mg per day in adults dealing with persistent stress and tension.
Start around 15 mg and slowly increase if needed, constantly tracking your reactions and ensuring your product is lab-tested and THC-compliant.
CBD for better sleep
Many people use CBD for better sleep, primarily to address nighttime restlessness. Shannon et al. (2019) found that taking around 25 mg of CBD in the evening helped improve sleep scores in most users.
If this is your goal, consider starting with 20–25 mg and monitoring how your sleep evolves over several nights before adjusting.
CBD for chronic pain relief
In more demanding situations, such as long-term discomfort, some users find that CBD for chronic pain is most effective at doses ranging from 50 to 100 mg per day. A study by Boyaji et al. (2020) supports the need for higher intake when the goal is to manage persistent physical tension.
As always, begin low and increase gradually, never exceeding 150 mg/day without medical guidance.
What CBD dosage is appropriate for seniors?
For older adults, it’s advisable to begin with 50–70% of the standard dose. Brunt et al. (2021), in Frontiers in Pharmacology, found that seniors metabolize cannabinoids more slowly.
Start with 5 mg daily and increase by only 2–3 mg every 5 to 7 days. Always consult a doctor before starting CBD, especially if you take medication regularly or have underlying health conditions.
How many CBD oil drops to reach your daily dose?
To determine your ideal CBD oil dosage, you’ll need to convert milligrams into drops—which many users find confusing. According to a 2022 study by Pavlovic et al. in the Journal of Cannabis Research, nearly 25% of CBD users struggle to calculate their daily dose accurately.
Mastering this step ensures better consistency and helps you tailor your intake based on your personal needs—whether you’re using low or high-strength oil.
ComprenUnderstanding your product: concentration, total mg, and volume
To dose your CBD oil precisely, identify the essential product details on the label. These parameters influence how many CBD drops per day you’ll need to reach your goal:
- CBD oil concentration: 5%, 10%, 20%, 30%, or 40%
- Total volume of the bottle: often 10 ml, 20 ml, or 30 ml
- Total CBD content, in milligrams (mg)
- Extract type: full-spectrum, broad-spectrum, or isolate
- Batch number and expiry date (for traceability and freshness)
- Lab test results, usually accessible via QR code
The concentration refers to how much CBD is present per milliliter of oil. For example, a 10% CBD oil contains 100 mg of CBD per ml. According to the French Observatory for Drugs and Drug Addiction (OFDT, 2021), the most common concentrations on the market range from 5% to 30%.
The type of extract also influences how your body might respond:
- Full-spectrum oils contain a range of cannabinoids and terpenes, which may support the “entourage effect”.
- Broad-spectrum oils retain these compounds without THC.
- Isolates are made of pure CBD with no other active hemp molecules.
How to calculate CBD (mg) per drop of oil
Each drop of CBD oil typically contains about 0.05 ml of liquid. Based on this standard, a 10 ml bottle generally holds between 200 and 240 drops or approximately 20 drops per milliliter. This makes it possible to calculate how much CBD per drop you’re consuming based on the product’s strength.
Two quick steps:
- Divide that value by the number of drops per ml
- Convert the concentration (%) to mg/ml
Determining the number of drops per bottle
A standard 10 ml CBD oil bottle contains roughly 200 drops, which equals about 20 drops per ml. This reference allows you to measure your CBD daily dose more accurately.
Converting concentration (%) to mg of CBD
To convert your oil’s concentration to milligrams, use this formula:
CBD oil concentration (%) ÷ 100 × 1000 = mg/ml
Example: A 10% oil = 10 ÷ 100 × 1000 = 100 mg of CBD per ml
This calculation helps you know the CBD oil strength and how potent each drop is.
Calculating mg of CBD in one oil drop
Once you know the concentration per ml, divide it by the number of drops per ml:
Example: 100 mg/ml ÷ 20 drops = 5 mg of CBD per drop
This makes it easy to adapt your CBD dosage to your needs without guesswork.
Dosage chart by CBD oil concentration (5%–40%)
Use this reference to quickly estimate how many drops you’ll need per day, depending on your oil’s strength and your target CBD dose:
Remember that the effective drop size may vary depending on the bottle and dropper used. Always verify your oil’s lab test report and manufacturer’s instructions to ensure proper dosing.
How to find your optimal CBD dose over time
Reaching your ideal CBD dosage isn’t something that happens overnight. Most users need between two to four weeks to fine-tune their intake. As Corroon and Phillips (2018) explain in Cannabis and Cannabinoid Research, this adaptation period is essential for maximizing the effects while minimizing discomfort.
This gradual process requires observation, consistency, and patience—but it’s the most reliable way to find what works for you over the long term.
Applying the “start low and go slow” method
The “start low and go slow” method is one of the most validated strategies for adjusting your CBD daily dose over time. MacCallum and Russo (2018), in the European Journal of Internal Medicine, recommend it to help balance effectiveness with your body’s tolerance.
This approach allows your endocannabinoid system to adapt, gradually avoiding underdosing and potential overstimulation. Unlike conventional medications, CBD doesn’t follow a linear dose-response pattern, making personalized progression essential.
How to gradually increase your CBD dose
You can safely raise your CBD dosage by following this step-by-step progression:
- Week 1: Start with 5–10 mg per day
- Week 2: Add +5 mg if effects are minimal
- Week 3: Increase by another 5 mg if needed
- General limit: Avoid exceeding 70 mg/day without medical advice
According to Larsen and Shahinas (2020), increasing your dose in 5–10 mg increments works well for most people—offering more control and a lower risk of discomfort.
Keeping a dosing journal: a key tool for adjustment
To adjust your CBD dose effectively, keep a simple journal to track your experience. Record the dosage, time of day, effects felt, and how long they lasted. This helps identify what works best and when.
By observing trends in your log over time, you’ll better understand your own CBD absorption rate and fine-tune your routine accordingly.
When and how to adjust your dose (up or down)
If, after 5 to 7 days, you’re not experiencing the desired results, it may be time to increase your CBD dose slightly. On the other hand, if you notice side effects like drowsiness, dry mouth, or dizziness, you may need to scale back.
Taylor et al. (2020), in their study An Analysis of Consumer Cannabidiol Usage Patterns and Perceptions, confirmed that most users go through multiple adjustments before reaching their “sweet spot.”
Why more isn’t always better: understanding biphasic effects
CBD has what’s called biphasic effects, meaning that low and high doses can trigger opposite reactions. In Frontiers in Pharmacology, Zuardi et al. (2017) describe an “inverted U-curve” where effects improve up to a point, then decline or even reverse if you go too high.
Simply increasing your CBD dosage doesn’t necessarily lead to better results. Finding and maintaining your personal optimal range is far more effective than chasing more potent effects.
Does dosage vary by CBD product form?
Yes, your CBD dosage can change considerably depending on how the product is used. This is due to differences in bioavailability, which refers to the proportion of CBD that enters your bloodstream. As Millar et al. (2018) note in the European Journal of Clinical Pharmacology, the same amount of CBD can have very different effects depending on the delivery method.
To tailor your dosage effectively, you need to understand the characteristics of each product form.
Dosage and use of CBD oil (sublingual administration)
⚠️ Important note for Swiss readers: In Switzerland, CBD oils are classified as chemical or cosmetic products, not food supplements. They must not be ingested. In most EU countries, oral use is also restricted. Only select markets like the US or UK permit CBD oils to be marketed as dietary supplements. Always read your packaging carefully and follow all warnings.
In countries where ingestion is permitted, sublingual application is one of the most efficient ways to take CBD oil. Many users learn how to use CBD oil by placing a few drops under the tongue and holding them for 60–90 seconds before swallowing; this method bypasses digestion and improves absorption.
This route is popular because it allows CBD to diffuse directly into the bloodstream via capillaries under the tongue. As Bruni et al. (2018) noted in Molecules, sublingual bioavailability can reach up to 35%, while oral ingestion may yield only 6–15%.
Dosage and use of capsules or edibles (oral)
CBD capsules and edibles offer an easy-to-use and consistent dosing, but they have a trade-off: reduced CBD absorption rate. Zgair et al. (2016), in the Journal of Controlled Release, showed that taking CBD with a high-fat meal can increase systemic exposure, but even then, oral bioavailability remains lower than sublingual forms—typically between 4% and 20%.
Key benefits:
- Accurate and repeatable dosage
- Convenient and discreet format
- Longer-lasting effects (6 to 8 hours)
However, effects take longer to set in, usually 45 to 120 minutes. You’ll need to anticipate your intake well ahead of time.
Dosage and use of other forms (e-liquids, topicals): a brief overview
Inhaled forms (e-liquids or vaporized flowers) offer the fastest absorption, with bioavailability between 50% and 80%. As Huestis et al. (2007) explain in Clinical Pharmacology & Therapeutics, effects can begin within 1 to 3 minutes—making this a preferred method for rapid onset. However, the duration is shorter (2–4 hours), and more frequent use may be required.
Topicals like CBD creams or balms are absorbed through the skin and act on local receptors. With 5–10% bioavailability, they’re not designed for systemic effects but can be helpful for targeted applications. Hammell et al. (2016), in the European Journal of Pain, recommend applying generously to the affected area 2–3 times per day for optimal results.
Precautions before setting your CBD dosage
Before choosing a CBD dosage, it’s essential to consider several safety and quality factors. These steps help ensure a smooth experience while minimizing any potential risks. In particular, product reliability, drug interactions, and legal constraints should be carefully evaluated.
Being informed about what you’re taking and how it can make all the difference in building a responsible and effective CBD routine.
How to verify product quality before dosing
Not all products are created equal, and buying quality CBD oil from transparent, verified sources is essential. A study by Bonn-Miller et al. (2017) in JAMA found that up to 70% of CBD products sold online contained more or less CBD than stated on the label.
To ensure safety and accuracy, always check:
- Third-party lab analysis (COAs)
- Origin of the hemp (ideally organic and European)
- Extraction method (CO₂ extraction is considered the safest)
- Brand reputation and customer reviews
Look for certifications and traceability measures to confirm that what you’re using is exactly what’s promised on the label.
Is there a recommended maximum CBD dose or overdose risk?
According to the World Health Organization (2018), CBD has a very favorable safety profile, even at high doses. Taylor et al. (2020), in the British Journal of Clinical Pharmacology, confirmed that no fatal overdoses have been reported—even at doses as high as 1,500 mg/day.
That said, very high intake can cause drowsiness, lethargy, or changes in liver enzymes. Most people experience consistent benefits without ever exceeding 100–150 mg per day.
Stick to the “start low and go slow” method unless a healthcare provider recommends otherwise.
CBD drug interactions: discuss with your doctor
One crucial but often overlooked point involves CBD drug interactions. Cannabidiol may inhibit certain liver enzymes in the cytochrome P450 family, which metabolize many medications. Zendulka et al. (2016) in Toxicology Letters identified several drug classes that may be affected, including:
- Blood thinners
- Antidepressants
- Antiepileptics
- Immunosuppressants
If you’re currently taking any prescription medication, consult your doctor before introducing CBD into your wellness routine. This step is essential to avoid altered drug efficacy or unwanted side effects.
CBD legality in Switzerland and THC limits (<1%)
In recent years, many consumers have raised questions about CBD legality and regulations in Switzerland, especially compared to stricter EU standards. Here, products containing less than 1% THC are legal, according to the Federal Office of Public Health (2020), while EU laws limit THC to just 0.2–0.3%.
That said, CBD products in Switzerland are not approved as food supplements. Depending on their format, they are classified either as cosmetics or chemical substances. Always check the product’s legal status—especially before traveling.
CBD and driving: precautions for dosage and safety
Most broad-spectrum and CBD isolate oils contain no THC and should not pose problems for drivers. But full-spectrum products, even when legally under 1% THC, require extra caution.
According to the Swiss Federal Roads Office (OFROU), roadside tests focus on THC only, and tolerance is zero. Using full-spectrum products regularly may, in rare cases, trigger a positive test, even when driving after CBD use was compliant.
Also, high doses of CBD may cause drowsiness or delayed reaction times. If you’re new to CBD or testing a new dose, avoid driving until you understand how your body reacts.
FAQ: common questions about CBD dosing
Can I use CBD daily without risk?
Most users can take CBD daily for 3 to 6 months without adverse effects.
Studies show good long-term tolerance, especially at moderate doses below 100 mg/day. Some people prefer a cycle of 5 days on and 2 days off. If you’re taking medication or have liver issues, always talk to a healthcare provider before long-term use.
Can CBD be addictive?
CBD is not considered addictive and does not produce withdrawal symptoms.
According to current research, the CBD addiction risk appears extremely low, as cannabidiol does not activate the brain’s reward circuits associated with dependency. You can stop at any time or adjust your CBD dosage freely, without triggering cravings or withdrawal—making it a well-tolerated option for regular use.
How long until you feel CBD’s effects?
Onset time depends on the product: from 1 to 90 minutes.
Vaping acts fastest (1–3 minutes), sublingual oils take effect in 15–45 minutes, and edibles may need 1–2 hours. Factors like your metabolism, dose, and whether you’ve eaten can influence the result.
What to do if you don’t feel any effects from CBD?
Increase your dose gradually by 5–10 mg every 3–4 days, up to 70 mg/day.
First, make sure you’re using a high-quality product. Then, consider trying a different delivery method (e.g., oil instead of capsule) or giving your body more time to adjust. A tracking journal can help identify patterns.
Is CBD dosage the same for pets?
Animals require much smaller doses than humans, typically 0.1 to 0.5 mg/kg.
Because of their more sensitive endocannabinoid systems, cats, dogs, and both
er pets process cannabinoids differently. The recommended CBD dosage for pets is significantly lower than for humans, and using only animal-specific products is crucial. Always begin with the minimum amount and adjust carefully if needed.
Conclusion: finding your perfect dose is a personal journey
There’s no universal rule regarding CBD dosage, and that’s perfectly normal. Your ideal amount depends on a wide range of personal factors: your weight, sensitivity, goals, and the type of product you choose.
That’s why experts consistently recommend the “start low and go slow” method: begin with a low daily amount, observe your body’s reactions, and adjust gradually over time. This approach helps you find your balance without overdoing it or wasting product.
Above all, remember the importance of choosing lab-tested, high-quality CBD products and keeping a simple record of your intake and effects. These small steps help you fine-tune your experience safely and effectively.
Lastly, CBD is a wellness supplement—not a medicine. If you’re taking other treatments or have specific health concerns, consult your doctor before starting.
