8 Best Full-Spectrum CBD Oils of 2026

Lazarus moves up to #2 on this re-check because the price gap is too large to rank around. The 120mL bottle holds 6,000mg for $120 — $0.020 per mg, less than half what we charge — and the 30mL/1,500mg is $40, or $0.027. Subscription takes the big bottle to $102, and their long-standing assistance program goes up to 60% off for qualifying buyers, which is the most generous access program in the category. Hemp is grown in-house in Central Oregon and batches are published with produce and best-by dates. They are also the most transparent brand here about what full-spectrum actually contains: the label states roughly 1.75mg of THC per mL, which is about 210mg of THC in the 120mL bottle. That number is worth sitting with if you are anywhere near a drug test, and it is why bottles like this one are what the incoming federal per-container cap is aimed at. Three flavors including an unflavored classic.

Charlotte's Web is the brand that put hemp-derived CBD on the map, and Original Formula survives in the current catalog as the 50MG oil at 50mg per mL — $119.99 for the 30mL and $214.99 for the 100mL. The small bottle is expensive at $0.080 per mg. The 100mL is the news: 5,000mg for $214.99 is $0.043 per mg, which matches botanCBD exactly and closes a gap that used to be the main reason to skip them. If you already trust the name and you buy the big bottle, there is no longer a price argument against it.

NuLeaf sells essentially one thing — full-spectrum CBD oil at 60mg/mL — in five sizes from 300mg to 6,000mg, and the focus shows in batch-to-batch consistency. The 6,000mg bottle is $124.70, or $0.021 per mg, second only to Lazarus. One caution from this re-check: their size pricing is not currently laddered the way you would expect. The 1,800mg was $62.58 and the 3,000mg was $115.49 the day we looked, which makes the mid-size bottle cheaper per mg than the larger one — a sign of promotional pricing on a single size rather than a stable price list. Do the division yourself before you pick a size. No flavor variants at all, which is the real trade-off against botanCBD or Charlotte's Web.

Cornbread extracts only from whole hemp flower rather than stalks and biomass, which produces a notably rich cannabinoid and terpene profile, and they carry USDA Organic. Two sizes: 750mg for $49.99 and 1,500mg for $74.99, or $0.067 and $0.050 per mg. That is a premium over botanCBD at the same 1,500mg strength, and Cornbread is unflavored where we are not. They are also unusually direct about THC content, labeling up to 2mg per serving — high for full-spectrum, and the reason their bottles are among the furthest over the incoming federal per-container cap.

Aspen Green carries USDA Organic plus Clean Green and vegan certification, and the Extra formula is their best seller at $144.99. They publish their own per-mg math rather than making you compute it, which we credit: they put Extra at $0.05 per mg, dropping to $0.03 on subscription. Taken at face value that is competitive per mg, but the $144.99 minimum is nearly five times botanCBD's entry price, so it only makes sense if you already know full-spectrum works for you and you buy at volume. Their lighter formulas run $99.99 to $149.99 and are priced by the brand at $0.04 to $0.07 per mg.

Bluebird has sold full-spectrum hemp extract since 2012 and runs a veteran and access assistance program. The Classic line is now sold by serving strength — 10mg or 25mg per serving — rather than by bottle total, which makes cross-brand per-mg comparison harder than it should be, so we are not going to publish a per-mg number we cannot verify from their own data. What we can report from this re-check: the 25mg 1oz bottle was $104.95 and in stock, while both the 10mg 2oz ($59.95) and the 25mg 2oz ($179.95) were listed as unavailable. Reliable product, thin availability. Confirm the size you want is actually in stock before you count on it.

Spruce's 2,400mg in a 30mL bottle is 80mg per mL — the most concentrated oil here, and a real advantage if you want a high dose without swallowing a lot of carrier oil. The price is the problem. It was $228.65 at this re-check, marked down from a $269.00 list, which is $0.095 per mg — more than four times Lazarus and roughly double botanCBD. You are paying for concentration and small-batch handling, not for value. Lab results are consistently clean and the brand has a loyal following, so we keep it on the list, but rank it last on price.
