Myth: More CBD = Better. The Wellness Industry's Favorite Lie.
I am Liv. Every gummy label says the same thing, just at a higher milligram count than last year. The implication is obvious: more CBD, more benefit. It's a straightforward pitch. It's also wrong.
Here's what the data actually says.
β‘ System Overview
More CBD doesn't mean more benefit. The research shows a clear sweet spot. Go past it and the effects reverse. 600 milligrams performed no better than a placebo in multiple anxiety trials.
High doses carry real risks. An FDA study found that daily CBD at common consumer doses caused measurable liver stress in 1 in 18 participants.
Nearly half of CBD products are mislabeled. Before the dosing question even matters, most consumers can't establish a reliable baseline because what's on the label often isn't what's in the bottle.

Have you ever just...doubled your CBD dose because it felt like it stopped working?
π The Investigation
CBD may help because it seems to affect the body systems involved in pain, mood, sleep, and inflammation. But the catch is that we still do not know the best dose for many conditions, how well it works long term, or which products are reliably labeled and safe, so the benefits can be real for some people but are not guaranteed.
β A word of caution
CBD is most concerning for pregnant or breastfeeding people, people with liver disease, and people taking medications that can interact with it β especially drugs that affect blood pressure, blood thinning, sedation, or are processed by the liver. Itβs also a bad idea for anyone with a known allergy or sensitivity to hemp/CBD.
CBD can also be risky because it can cause side effects like drowsiness, diarrhea, dizziness, and appetite changes. Moreover, it can change how other medicines work by slowing or altering their breakdown in the liver.
Consult your doctor before using CBD to make sure itβs safe for YOU.
π The Bell Curve Nobody Talks About
Cannabidiol (CBD) is a naturally occurring compound found in the Cannabis sativa plant. It is one of over 100 cannabinoids in cannabis, and the second most abundant after THC (tetrahydrocannabinol). It interacts with the endocannabinoid system β a network of receptors throughout the body that helps regulate mood, sleep, pain, and immune response.
Based on consumer surveys and the available research, the top reasons people use CBD are:
Pain and inflammation: the most common use by a wide margin, particularly chronic pain, arthritis, and muscle soreness
Anxiety: general anxiety, social anxiety, and stress management
Sleep: trouble falling asleep or staying asleep
CBD doesn't work like most supplements. Take too little and nothing happens. Hit the right range and you get results. Go too high, and the benefits reverse. The wellness industry calls this a "strength" problem. Pharmacology calls it a biphasic response β and it's the detail that makes the "more is better" pitch collapse.
A small amount of CBD can wake your system up. Too much shuts it down. And what counts as "too much" is different for everyone. The same dose from the same product can help one person and harm another.
The wellness industry ignores this almost entirely. That $80 "ultra-strength" tincture may be working against you.

π The Anxiety Numbers Are Uncomfortable
This too-much/too-little effect shows up most clearly in anxiety research, and the pattern is consistent enough to cause real problems for brands selling high-dose products.
In controlled studies using public speaking tasks, 300 mg of oral CBD significantly cut self-reported anxiety compared to a placebo, but both the low dose (150 mg) and the high dose (600 mg) delivered no meaningful difference from a sugar pill. Multiple trials produced the same inverted U-shaped pattern.
600 milligrams β A high dose that many products now push as standard β did nothing notable for health.
A review of 44 published studies covering CBD's effects on pain, anxiety, and sleep confirmed that this dose-response pattern holds for all these conditions β that thereβs no significant difference between the low dose and high dose β and called for tighter dose research before the findings could responsibly guide consumer use.
The market ran ahead of the science. As it tends to do.

β¬ Higher Doses Can Stress Your Liver
The "take more" conversation gets even worse when you look at what higher doses actually do to liver health. The FDA tested this directly.
An FDA study gave participants 250β550 mg of CBD daily for 28 days. Researchers found that 5.6% experienced significant liver enzyme elevations β a marker of liver stress β while no one in the placebo group did. Nearly 5% hit the threshold for potential drug-induced liver injury.
Consumer products currently market these doses as normal. The liver doesn't care about the branding.
π« You Don't Know What's in the Bottle
Say you're trying to find your sweet spot. Take too much and you've already gone past it. Now factor in this:
Researchers testing 80 commercially available CBD products found that nearly HALF failed basic accuracy standards.
Twelve products delivered less than 90% of what the label claimed, and 25 delivered more than 110%.
You don't actually know what you're taking. The "more CBD" strategy falls apart completely when your starting dose is a guess.
#β£ Number of the week: 46%
In a test of 80 CBD products, this is the percentage of products tested that failed basic label accuracy standards. Nearly half. Before the bell curve even becomes relevant, most consumers can't pin down a reliable dose.
π¦Ύ The Liv protocol
What the data actually supports:
Start low. Human anxiety trials put the effective range around 300 mg oral β not 600 mg, not 1,000 mg.
If benefits fade after you increase your dose, go back down. Across multiple trials, small doses of inhaled CBD produced measurable effects, while incrementally higher single doses delivered no consistent improvement. The bell curve wins. Work with it.
Treat your label as an estimate. Buy from brands that publish third-party lab results. Match those results to the batch number on the product.
Don't treat long-term high-dose use as safe. The FDA liver data is a signal, not a scare tactic.
The "more = better" logic works for a lot of things. Based on how CBD actually behaves in the body, this isn't one of them. The industry knows this. They're counting on you not to.
