Koi Naturals CBD Tincture Review (2026)
Koi sells exactly one CBD oil: 1000mg of broad-spectrum extract in 30ml of MCT, in five flavours, for $69.99. No 250mg starter bottle, no 3000mg jug. That single-strength decision is the most interesting thing about this product and the main reason it does not score higher.

Dosing and the single-strength problem
At roughly 33mg per millilitre, a full dropper is a substantial dose and a quarter dropper is about 8mg. That granularity is the real advantage a tincture has over a gummy: you can find your dose rather than accepting the manufacturer’s. If you are starting out, our how much CBD should you take guide covers where to begin and how to step up.
The problem is that 1000mg is the only option. Someone taking 10mg a day and someone taking 100mg a day buy exactly the same bottle. For the light user, $69.99 buys a hundred days of supply and a bottle that will be open for months. For the heavy user, it is ten days and an expensive habit. Most serious tincture brands solve this with a 500mg / 1000mg / 3000mg ladder; Koi does not, and it is the single biggest gap in an otherwise strong catalogue.
Broad spectrum also means no THC to speak of, which is genuinely useful. If you are drug tested, this is one of the few Koi products we would recommend without a caveat — though read does hemp THC show up on a drug test anyway, because no hemp product is a guarantee.
The five flavours
Spearmint
The one that does the most work masking the hemp. Clean finish, no lingering grassiness, and it does not fight with coffee if you dose in the morning.
Orange
Bright and unfussy. The safest choice if you are ordering without tasting and you dislike mint.
Lemon Lime
The most assertive of the five. Good if hemp taste is the thing putting you off tinctures entirely.
Strawberry
Candy-adjacent. Fine, but it reads more like a supplement flavouring than the others.
Natural
Unflavoured, so you taste the MCT and the hemp. Choose it if you mix into food or drink rather than dosing sublingually.
Value, in context
7¢ per milligram is average for a broad-spectrum tincture. It is not a bargain and it is not a rip-off. What is worth knowing is how it sits against Koi’s own catalogue.
| Koi product | Format | Cost per mg CBD |
|---|---|---|
| Full Spectrum CBD Balm 3000mg | Topical | $0.033 |
| Complete Full Spectrum Gummies 120ct | Edible | $0.043 |
| Naturals Broad Spectrum Tincture | Sublingual | $0.070 |
| Balance Bar CBD Vape | Inhalable | $0.072 |
| Anytime Balance Gummies 60ct | Edible | $0.100 |
The premium over the Complete gummies buys you two things: dose control, and a broad-spectrum extract with effectively no THC. If neither matters to you, the gummies are the better buy — see our Koi CBD gummies review for the full comparison. Our price per milligram guide explains the method.
Who this is for
Buy it if
- You are drug tested and need a THC-free CBD product
- You want to control your dose rather than take a fixed 10mg or 25mg
- You take somewhere between 20mg and 50mg a day, where a 1000mg bottle lasts a sensible length of time
- You dislike gummies, or already take too many things in sweet form
Skip it if
- You want a full-spectrum extract — Koi does not make one in tincture form
- You need a high daily dose; there is no larger bottle and this gets expensive fast
- You are trying CBD for the first time and would rather risk $40 than $70
- Cost per milligram is your main criterion — buy the Complete gummies instead
Verdict
A well-made, well-flavoured, properly tested broad-spectrum tincture that is held back by a product decision rather than a formulation one. Koi built a good CBD oil and then offered it in exactly one strength.
If you fall in the middle of the dosing range and you need low THC, it is a straightforward recommendation. If you dose heavily, or you want to start small, the absence of a strength ladder will cost you money.
