YOU TRIED CBD.
HERE'S WHY IT DIDN'T WORK.

YOU TRIED CBD. HERE'S WHY IT DIDN'T WORK.

Natural Dos is built around CBDA — the original hemp compound your body absorbs over 500% better than standard CBD. Most hemp companies destroy it. We don't.

Founded by Luigi Bertoli MD and Colin Reily PhD. Research-backed.

★★★★★ ★★★★★ Over 10,000 customers — most of them former CBD skeptics.
“I've taken CBD for months and felt basically nothing. Within a week of Natural Dos, I was sleeping through the night.”

WHY MOST HEMP PRODUCTS DON'T WORK

HEAT DESTROYS THE BEST PART

HEAT DESTROYS THE BEST PART

Most hemp companies use heat to process their product. That converts CBDA into CBD — a far less absorbable compound.

YOUR BODY ABSORBS 500% MORE

YOUR BODY ABSORBS 500% MORE

At the same dose, your body absorbs CBDA over 500% better than CBD. That's not marketing — that's pharmacokinetics.

WE COLD-PURIFY TO PRESERVE IT

WE COLD-PURIFY TO PRESERVE IT

Natural Dos uses a low-temperature purification process that keeps CBDA intact — the way the hemp plant made it.

The hemp plant makes CBDA naturally. Most companies cook it away. We don't. That's the whole difference.

WHAT ARE YOU LOOKING FOR?

MOST POPULAR
Stress & Anxiety

Stress & Anxiety

A calmer baseline. Less noise. All day.

You're not looking to be sedated. You want the underlying hum to quiet down. CBDA's superior absorption means more of the compound actually reaches the receptors your body uses to regulate stress response — without THC, without side effects.

Sleep

Sleep

Fall asleep. Stay asleep. Wake up clear.

Most sleep products knock you out or leave you groggy. CBDA supports your body's natural sleep regulation. The result most customers describe: falling asleep without effort and waking up actually rested.

Physical Calm

Physical Calm

Morning stiffness. Body tension. Daily ease.

CBDA supports healthy inflammatory response. When your body absorbs more of the compound, more of it reaches the tissues that need it. Customers notice it most in the morning.

WHAT CUSTOMERS ARE SAYING

MOST OF THEM HAD ALREADY GIVEN UP ON CBD.

★★★★★
Ive tried probably five different cbd things over the past few years and honestly gave up on all of it. My daughter sent me a link to this and I figured why not. Two weeks in and I'm actually sleeping through the night. Forgbot what staying asleep is like. I don't know whats different about it but something is.

I was ready to write this off like everything else. I'm 62, I've been dealing with this low-grade anxiety since I retired and nothing really touched it. These gummies are the first thing that's actually taken the edge off without making me feel foggy or out of it. I take one around 7pm and by the time I'm watching TV I just feel normal. Which is all I wanted.

★★★★★
I blew probably $200 on CBD products that did absolutely nothing. A friend told me about the CBDA difference and I looked it up, it actually made sense. I've been on these for about 6 weeks now. I won't say it's magic but my sleep is better, I feel less wound up during the day, and my knees are noticeably less stiff in the morning. That's three things I wasn't expecting.

Waking up at 3am was just my life for like two years. I'd lie there with my brain just going, going, going. I tried melatonin, magnesium, all of it. These gummies are the only thing that actually keeps me asleep. I don't know if it's the CBDA or what but I'm not questioning it.

★★★★★
What I liked was that they actually explained why it works differently. I'm not someone who just takes things without understanding them, so the fact that there's a real doctor and scientist behind it meant something to me. The 100day trial sealed it. You don't offer that if you're not confident in what you're selling.

Racing thoughts, trouble sleeping, feeling on edge. that was just my everyday for the past couple years. I was skeptical of the whole hemp thing because I tried regular cbd and felt nothing. These are genuinely different. I feel calmer without feeling sedated. Big difference.

★★★★★
My doctor actually suggested I look into hemp for stress after I didn't want to go the prescription route. I did a lot of research before I landed here. The science checked out, the founders have real credentials, and the reviews weren't the usual fake-sounding stuff. I've been taking them for a month. I'm not cured of stress but I handle it a lot better now. That's real.

Ill be honest, I rolled my eyes at this. My husband bought it for me because I'd been complaining about my sleep for months. I take one softgel about an hour before bed. I fall asleep faster. I wake up and actually feel rested. I don't understand the science but apparently there's a real reason this one is absorbed better than regular CBD. Whatever it is, it's working.

★★★★★
Ordered the gummies mostly for sleep but they seem to help with my overall anxiety too, which I didn't expect. It's not a dramatic thing. It's more like... I'm not as reactive. My husband noticed before I did. I've reordered twice.
Margaret S. · Verified Customer
★★★★★
I was nervous ordering from a company I didn't know. Called their customer service before I ordered just to ask some questions. Whoever I talked to actually knew what they were talking about, explained the CBDA vs CBD thing without being pushy about it. That did more for me than any ad. Been a customer for four months now.

WHY THIS COMPANY EXISTS

FORMULATED BY DOCTORS WHO COULDN'T FIND A PRODUCT WORTH RECOMMENDING.

Dr. Luigi Bertoli (MD, Johns Hopkins — hematology/oncology) and Dr. Colin Reily (PhD, UAB — molecular pathology) spent years watching patients look for alternatives and coming up empty. Most hemp products on the market delivered inconsistent results because the underlying compound — CBDA — was being destroyed during production. They didn't find a better solution, so they built one.

Colin uses CBDA personally. Luigi recommends it to people in his network.

HONEST ANSWERS

THE QUESTIONS WE GET MOST OFTEN.

What's the difference between CBDA and CBD? +

CBDA is the raw compound the hemp plant naturally produces. CBD is what CBDA becomes when it's heated through a process called decarboxylation. Most hemp companies heat their product during purification, converting CBDA into CBD.

Your body absorbs CBDA over 500% more efficiently than CBD. That's the entire reason most CBD products disappoint people — not because hemp doesn't work, but because they're getting the less bioavailable compound.

Will any of these products make me feel high? +

No — for the Calm+ Softgels and CBDA Vegan Gummies. Both contain zero THC, confirmed by third-party lab testing. No intoxication, no altered state, no drug-test concern.

The CBDA Gummies with Delta-9 THC do contain a small, precise amount of THC and are intended specifically for sleep. Those are for adults 21+ who want the sleep-support benefit of a low-dose THC + CBDA combination.

I've tried CBD before and felt nothing. Why would CBDA be different? +

Because you were taking a compound with dramatically lower bioavailability. If your CBD was made using heat processing (which describes almost all of it), your body was absorbing a fraction of the dose listed on the label. CBDA doesn't have that problem — the absorption advantage is real and measurable. That's why we built the brand around it.

How long does it take to work? +

Stress and anxiety: many customers report noticing a difference within the first few days. Sleep: most within the first week. Physical ease: tends to build over 2–4 weeks. We say give it 30 days to genuinely evaluate it. That's also why the guarantee is 100 days — you have time to actually know.

Are these third-party lab tested? +

Yes. Every batch is tested by an independent ISO-certified laboratory for cannabinoid potency, THC content, heavy metals, pesticides, and microbial contamination. Lab results are available on our website.

Which product should I start with? +

It depends on the benefit your trying to get and the problems your trying to solve. CLICK HERE to help find what works for you.
