Pick by use case

Pick 500mg bottle if…
  • You have never used this brand or this flavor
  • You want a two-to-four-week experiment without a drawer bottle
  • You are still deciding whether CBD is for you
  • You travel and want a smaller bottle in a bag
Pick 1,500mg bottle if…
  • You already finished a 500mg bottle of the same spectrum and flavor
  • You take 15–25mg most days
  • You want better per-mg without jumping to 6,000mg
  • You are ready for a 30-day-plus habit

The 500mg bottle is expensive per milligram on purpose

$0.07/mg looks bad next to $0.047/mg and worse next to $0.0275/mg at 6,000mg. That is not a trick. A trial is priced so you can quit without resenting a flagship. If you already know your serving, do not stay on 500mg to 'save money' — you will spend more per month reordering the small bottle.

At 20mg a day, 500mg is a 25-day bottle. That is a fair experiment. It is a bad subscription. The 1,500mg at the same serving is about two and a half months, which is why it is the daily-driver size on our daily-use and focus lists.

Dropper math changes when the bottle gets stronger

Both bottles are 30mL. The 500mg is 16.7mg/mL, so 15mg is most of a dropper. The 1,500mg is 50mg/mL, so 15mg is about a third of a dropper. People who jump sizes without re-reading the label take three times the serving they meant. The graduated dropper is the tool; the label is the instruction.

Full-spectrum 500mg is $30; full-spectrum 1,500mg is $65. Same size logic, different spectrum. If you are drug-tested, stay on broad-spectrum for both sizes.

When 6,000mg is the actual next step

If you already take 40–50mg a day, 1,500mg becomes a one-month bottle and the 6,000mg flagship ($165, $0.0275/mg; $99 on subscribe) is the cheaper habit. That is a third page's job. This URL is the first fork: trial vs daily driver.

FAQ

Should my first bottle be 1,500mg?

Only if you already know the serving and the flavor from another brand and you are sure about spectrum. Most first bottles should be 500mg.

Is 1,500mg three times stronger per drop?

Yes, on our 30mL bottles. Same dropper, three times the milligrams per milliliter. Re-measure. Do not keep the old drop count.

Which size is better on subscribe-and-save?

1,500mg for most daily users. 500mg on a cadence is how you get a recurring charge on a trial. 6,000mg if you already dose high.

Does size change the spectrum?

No. Broad-spectrum 500mg and 1,500mg are the same formula at different concentrations. Full-spectrum is a separate product line with its own two sizes.
