Koi Naturals Broad Spectrum CBD Tincture
Koi Naturals Broad Spectrum CBD Tincture
One thousand milligrams of Koi PRIZM broad-spectrum hemp extract in 30ml of MCT oil — about 33mg of CBD per millilitre — in Orange, Lemon Lime, Spearmint, Strawberry or Natural.
Broad spectrum means CBD plus the minor cannabinoids with THC listed at 0.001 percent, which makes this the Koi product we would point anyone who is drug tested towards first. It is also the only tincture Koi makes, which is its one real weakness.
Quick Verdict: Who Is This For
Buy this if you want to control your own dose. A tincture is the only format that lets you take 8mg one day and 40mg the next, and at 33mg per millilitre a quarter dropper is a genuinely useful increment.
Skip it if you take a high daily dose. Koi sells this in 1000mg and nothing else, so a heavy user is buying a $69.99 bottle every ten days. At that point the Complete Full Spectrum gummies are far better value per milligram.

What This Does Well
Dose control
A dropper at 33mg per millilitre lets you find your own dose instead of accepting a fixed 10mg or 25mg gummy. This is the whole argument for tinctures.
Genuinely low THC
PRIZM broad spectrum is listed at 0.001 percent. If your job tests you, this is the safest thing in the Koi catalogue short of not buying hemp at all.
Flavours that work
Spearmint does the most to mask hemp and Orange is the safest blind buy. Natural exists for anyone mixing it into food or coffee.
Pros and Cons
Pros
- 33mg per millilitre allows precise dosing
- Broad spectrum with THC at 0.001% — the drug-test-safer choice
- MCT carrier aids absorption
- Five flavours, including an unflavoured option
- Ships to all 50 states with no restrictions
- Batch-specific COA behind a QR code
- 90-day full refund window
Cons
- Only one strength — 1000mg or nothing
- Expensive per milligram against Koi’s own gummies
- No full-spectrum tincture in the Koi range at all
- $69.99 is a lot to spend to find out whether CBD suits you
Will This Get You High?
No. CBD is not intoxicating, and this is a broad-spectrum extract with THC listed at 0.001 percent, a level Koi describes as undetectable. There is no version of this product that produces a high, at any dose.
On drug testing
Broad spectrum lowers the risk substantially compared with a full-spectrum product, and this is the Koi item we would choose if testing is a concern. No hemp product can be guaranteed safe on a drug test, however. Our guide to hemp THC and drug tests covers why.
Where to Buy
Direct from Koi. There is one strength and one bottle size, so the only decision is flavour — and if you are unsure, Spearmint or Orange are the safe picks.
Koi’s published refund policy gives a full refund on returns started within 90 days of purchase, and 50% back between 91 and 150 days. Shipping is free on orders over $69, and current discount codes are on our Koi coupon page.
