There is no official CBD dosage. The FDA has not set a serving size for over-the-counter CBD, so most people use a "start low, go slow" approach: begin with a small, measured amount, keep it the same for several days, and change it slowly, if at all. Your doctor should be part of that decision, especially if you take any medication.
What we can do is help with the math. This guide shows how many milligrams are in a dropper, capsule, gummy or teaspoon of Tahoe CBD products, explains what "CBD dosage by weight" charts really mean, and covers the safety points regulators have raised. It is general information, not medical advice.
Why there is no official CBD dosage
For most things you swallow, a regulator or a drug label tells you how much to take. CBD is different:
- No FDA serving size. The FDA has not approved any over-the-counter CBD product and has not set an amount for one. The serving size on a CBD label is chosen by the company that makes it.
- The only FDA-approved CBD product is a prescription drug. It is a purified CBD medicine, and its dose is set by a doctor for each patient based on body weight and close monitoring. That dosing does not carry over to tinctures, gummies or capsules sold in shops.
- Research uses many different amounts. Published studies have tested CBD across a wide range of milligrams, in controlled settings, often with purified CBD. Those numbers are not instructions for everyday products.
One regulator has offered a reference point. In October 2023, the UK's Food Standards Agency advised healthy adults to limit CBD from food products to 10 mg a day, based on an acceptable daily intake of 0.15 mg per kilogram of body weight. The UK government summary of that advice explains the change. That is precautionary consumer advice in the UK, not a US rule and not a recommended dose. It is still a useful reminder that more is not automatically better.
CBD dosage chart: milligrams in Tahoe CBD tinctures
This chart shows how much CBD is in common amounts of our Full Spectrum CBD Oil Tincture. Each bottle holds 30 ml, and a full dropper is about 1 ml. It is a milligram chart, not a recommendation.
| Bottle strength | Per full dropper (1 ml) | Per half dropper (0.5 ml) | Per quarter dropper (0.25 ml) |
|---|---|---|---|
| 1,000 mg in 30 ml ($58.00) | About 33 mg | About 17 mg | About 8 mg |
| 2,000 mg in 30 ml ($73.00) | About 67 mg | About 33 mg | About 17 mg |
| 3,000 mg in 30 ml ($85.00) | About 100 mg | About 50 mg | About 25 mg |
Fixed-serving products are easier, because the milligrams are printed per piece:
| Product | Per serving unit | Per container |
|---|---|---|
| Full Spectrum CBD Capsules | 10, 25 or 50 mg CBD per capsule | 30, 60 or 90 capsules (300 to 4,500 mg) |
| Full Spectrum CBD Gummies | 50 mg CBD and 10 mg CBG per gummy | 15 count (900 mg) or 30 count (1,800 mg) |
| Sleep Gummies | 25 mg CBD and 25 mg CBN per gummy | 15 count (750 mg) or 30 count (1,500 mg) |
How to work out your milligrams
For any tincture, the formula is the same:
- Divide the total milligrams by the bottle size in milliliters. 1,000 mg in 30 ml is about 33 mg per ml. A pet example works the same way: 750 mg in 30 ml is 25 mg per ml.
- Multiply by the amount you take. A quarter dropper (0.25 ml) of a 2,000 mg bottle is 66.7 mg per ml times 0.25, or about 17 mg.
- Check the total for the day. If you take CBD more than once a day, or use more than one product, add them up.
Two common mix-ups to avoid. First, the big number on the front of a bottle is the total for the whole bottle, not one serving. Second, switching strengths changes everything: a full dropper of the 3,000 mg bottle holds three times the CBD of a full dropper of the 1,000 mg bottle. If you change products, do the math again.
Start low, go slow: a simple framework
If you and your doctor decide CBD is worth trying, this is the general approach many people use. It is a framework for being careful, not a dosing schedule.
- Pick a product with an easy-to-measure serving. A 10 mg capsule, or a quarter dropper of a 1,000 mg tincture (about 8 mg), makes small amounts simple.
- Start with the smallest serving on the label, or less. Never start above the label's suggested serving.
- Stay consistent. Take the same amount at about the same time for at least several days before deciding anything.
- Change in small steps. If you adjust, do it gradually and give each change time.
- Stop if something feels off, and call your doctor.
Writing things down makes this much easier. A simple log like this one helps you and your doctor see what you actually took:
| Date | Product and strength | Amount | Milligrams | Time and food | Notes |
|---|---|---|---|---|---|
| Day 1 | 1,000 mg tincture | 0.25 ml | About 8 mg | 8 pm, after dinner | Anything you noticed |
| Day 2 | 1,000 mg tincture | 0.25 ml | About 8 mg | 8 pm, after dinner |
CBD dosage by weight: what those charts mean
You will find charts online that list a CBD dosage by weight, such as a number of milligrams per pound. No US regulator publishes those charts for over-the-counter products, and the numbers vary widely from site to site. Read them with caution.
Body weight is one factor, but it is not the only one. How CBD affects you can also depend on:
- The format. Oil held under the tongue, a capsule you swallow and a drink all reach your body in different ways and at different speeds. Products you swallow go through digestion first, so they take longer.
- Food. Taking CBD with a meal, especially one with some fat, can change how much your body absorbs. Try to be consistent.
- Medications. CBD can interact with other drugs. This is one of the main reasons to involve your doctor or pharmacist.
- Your own body. Metabolism, age and health all play a part.
The UK figure mentioned above is a rare example of a weight-based number from a food regulator, and it works out to roughly 10 mg a day for an average adult. It is an upper limit for caution, not a target.
How much CBD tincture should I take?
Start with the serving on the label, or less, and measure it the same way every time. Starting with a quarter or half dropper is a common way to go slowly. From the 1,000 mg bottle, that works out to roughly 8 to 17 mg of CBD. Each 30 ml bottle holds about 30 full droppers.
Hold the oil under your tongue for a short time before swallowing, keep the amount steady for several days, and log what you take. Our guide on how to use CBD oil walks through the steps in more detail.
Is there a CBD dosage for a health condition?
No reliable one exists for over-the-counter products, and we do not recommend amounts for any health condition. The FDA has not approved any over-the-counter CBD product for any medical use. Studies that have looked at specific conditions used varied amounts, often purified CBD, under medical supervision, and their results cannot be turned into a number for a gummy or tincture.
If you are dealing with a health concern, the right first step is your doctor, not a milligram chart. Some customers simply prefer to take CBD at a certain time of day, such as the evening. That is a personal routine, and it is not something we can promise will change how you feel.
Safety points regulators have raised
The FDA has said that CBD can cause side effects and has the potential to cause harm. Points it has raised include:
- Liver. Liver injury was seen in some studies of CBD.
- Drug interactions. CBD can change how other medicines work.
- Drowsiness. Do not drive or operate machinery until you know how a product affects you.
- Stomach and mood changes, such as diarrhea, reduced appetite or irritability.
- Pregnancy and nursing. The FDA advises against using CBD while pregnant or breastfeeding.
Most of our CBD products are full spectrum, so they contain trace THC that can add up with daily use. If you are drug tested, read our guide on whether CBD shows up on a drug test first. Keep all products away from children and pets. All of our products are for adults 21+.
How Tahoe CBD fits in
If measuring matters to you, our lineup makes it straightforward. Full Spectrum CBD Capsules come in 10, 25 or 50 mg per capsule, so you can start small and know exactly what you took. Our tinctures come in three strengths, each with a dropper. Our Full Spectrum CBD Gummies hold 50 mg of CBD and 10 mg of CBG each.
Buying for a pet? Dosing for animals is a separate question for your veterinarian. Start with our guides to CBD dosage for dogs and CBD for cats.
