How to Compare CBD Strengths Properly

Comparing CBD strengths becomes straightforward once you know what the numbers on the label actually mean. This guide shows you exactly how to read a CBD label, work out real concentration (mg per ml and per drop), and choose a practical strength for your routine—using clear UK‑focused examples from Swiss Peak Health’s range of British‑made CBD oils. Swiss Peak Health is a British brand based in Liverpool, and our CBD oils are made in the UK with UK delivery including free next‑day delivery on orders over £50 (see Shipping policy on our site for details).

The quick answer: how to compare CBD strengths properly

• Total mg on the bottle is the amount of CBD in the whole bottle (for example, 3,000mg in 30ml).
• Concentration = total mg ÷ bottle size (ml). That gives you mg per ml, which is the fairest way to compare oils of different sizes.
• Per‑drop estimate: most droppers deliver about 20 drops per ml. So a 30ml bottle has roughly 600 drops; a 100ml bottle has roughly 2,000 drops. Per‑drop CBD ≈ total mg ÷ total drops.
• Value check: work out cost per mg (price ÷ total mg) to compare like‑for‑like across strengths and sizes.
• Start with a sensible strength for you: pick a bottle that makes it easy to measure small, consistent amounts. Increase only if you want the convenience of fewer drops for the same total intake. If you’re unsure, speak to your GP or a pharmacist.

What the label numbers mean (mg vs ml)

The headline number (for example, 500mg, 1,000mg, 3,000mg or 6,000mg) is the total CBD in the bottle. To know how strong an oil really is, convert that into mg per ml:

• 3,000mg in 30ml → 3,000 ÷ 30 = 100mg/ml.
• 6,000mg in 30ml → 6,000 ÷ 30 = 200mg/ml.
• 12,000mg in 100ml → 12,000 ÷ 100 = 120mg/ml.
• 25,000mg in 100ml → 25,000 ÷ 100 = 250mg/ml.

That mg/ml figure tells you how concentrated each drop is, and therefore how many drops you’ll typically use for the same total intake.

Per‑drop maths: quick estimates you can use

Using the 20‑drops‑per‑ml rule of thumb:

• 30ml bottles: ~600 drops total. Per‑drop CBD ≈ total mg ÷ 600.
• 100ml bottles: ~2,000 drops total. Per‑drop CBD ≈ total mg ÷ 2,000.

Examples from Swiss Peak Health:

• CBD Oil 500mg | 30ml Starter Strength → about 0.8mg per drop (500 ÷ 600).
• Mint CBD Oil 1,000mg | 30ml → about 1.7mg per drop (1,000 ÷ 600).
• CBD Oil 3,000mg | 30ml → about 5mg per drop (3,000 ÷ 600).
• CBD Oil 6,000mg | 30ml → about 10mg per drop (6,000 ÷ 600).
• CBD Oil 12,000mg | 100ml → about 6mg per drop (12,000 ÷ 2,000).
• CBD Oil 25,000mg | 100ml → about 12.5mg per drop (25,000 ÷ 2,000).

These are practical estimates; always follow the product label for directions and adjust only if appropriate for you. If you take medication, have a medical condition, are pregnant or breastfeeding, ask a GP or pharmacist for advice first.

Compare popular CBD strengths at a glance

Use this simple matrix to compare bottle size, real‑world concentration and dosing flexibility.

Choosing a sensible starting strength (without overcomplicating it)

• If you want maximum flexibility: a lower strength 30ml oil (for example, 500–1,000mg) gives very small per‑drop amounts, so it’s easier to make tiny, consistent adjustments. If you prefer flavour masking, a 1,000mg option such as Apple 1,000mg | 30ml can help.
• If you already know roughly what you plan to take each day: a mid‑strength 3,000mg 30ml makes it simple to reach typical daily amounts in a few drops.
• If you prefer fewer drops and larger bottles: a high‑strength 6,000mg 30ml or 12,000–25,000mg 100ml provides higher concentration and long supply, which many people choose for convenience and value per mg.

Oil vs gummies: does format change the comparison?

Strength maths works the same way, but formats differ in convenience. Oils let you fine‑tune per drop; gummies provide a fixed amount per piece (handy if you don’t want to measure). If you’re comparing edibles by value, match total CBD per pack, CBD per piece and price per mg. When you’re ready to compare a simple, good‑value pick either way, consider the 3000mg CBD Oil or 3200mg CBD Gummies promotion. For broader context, read CBD Oil vs Gummies: Which Format Suits Your Routine? and How to Compare CBD Gummies by Strength, Pack Size and Price.

Which Swiss Peak strength fits typical preferences?

• Gentle and precise: 500mg CBD Oil | 30ml or a flavoured 1,000mg oil such as Mint 1,000mg | 30ml if you want taste masking.
• Balanced, everyday routine: 3,000mg CBD Oil | 30ml for efficient, small‑drop measuring.
• High‑strength convenience: 6,000mg CBD Oil | 30ml when you want fewer drops for the same total intake.
• Large‑format, long supply: 12,000mg CBD Oil | 100ml or the very concentrated 25,000mg CBD Oil | 100ml if you prefer stocking up.

What about spectrum (broad, full or isolate)?

Spectrum describes the cannabinoid profile, not the raw strength. You can choose a lower or higher strength in any spectrum. If you’re weighing this up, our primer explains the differences: Broad‑Spectrum, Full‑Spectrum and CBD Isolate Explained. If you specifically need to understand THC status, read How to Check Whether a CBD Product Is THC‑Free.

How to judge value fairly (without guessing)

1. Confirm the label: check total mg and bottle size.
2. Calculate mg/ml and per‑drop using the quick maths above.
3. Work out cost per mg: divide the price by total mg. A higher‑strength bottle can offer a lower cost per mg, even if the upfront price is higher.
4. Check third‑party testing: choose brands with batch lab reports so you know the stated strength matches the contents. For help reading reports, see How to Read a CBD Lab Report.

Practical tips for UK shoppers

• Follow UK supplement guidance: CBD oils are sold as food supplements in Great Britain. Read and follow the directions and warnings on the product label, and ask a GP or pharmacist for personalised advice.
• Prefer UK‑made products with accessible testing: Swiss Peak Health formulates and manufactures CBD oils in Britain and provides batch lab information for transparency.
• Delivery and value: Larger bottles can last longer and reduce re‑ordering. Swiss Peak offers UK delivery with free next‑day delivery over £50, which can improve overall value for regular shoppers.

Frequently Asked Questions

Is a bigger mg number always stronger?

It’s only part of the picture. A larger mg total in a much bigger bottle can have a lower mg/ml concentration than a smaller, higher‑concentration oil. Always compare mg/ml (and if useful, mg per drop).

How do I switch from a lower to a higher strength sensibly?

Match the total amount you typically take and convert it to the new oil’s per‑drop concentration so you’re not overshooting. If in doubt, seek advice from a GP or pharmacist and follow the product’s label directions.

Will a higher strength taste stronger?

Higher‑concentration oils often taste more “hempy” per drop. Flavoured options like Cherry 1,000mg | 30ml or Mint 1,000mg | 30ml can help if you’re taste‑sensitive.

How should I compare oils to gummies?

Use the same method: check total CBD per pack, CBD per serving, and cost per mg. Oils are flexible per drop; gummies are pre‑measured and convenient. See our format guide: CBD Oil vs Gummies: Which Format Suits Your Routine?.
