Introduction
Finding a decent CBD oil right now is not simple. There are bottles everywhere, all saying they are the best, and it gets confusing. People mostly want three things: something that works, something that is safe, and something that is not going to empty their wallet.
The truth is, not every CBD oil is the same. Some companies really test their products, check for quality, and share results. Others just put a label on a bottle and hope no one looks too close. That is why lab tests and government rules matter.
What I am going to do here is walk through how CBD oil is checked in the United States, what to watch for when you buy, and then show you the oils from Mary Jane’s Bakery Co that stand out this year. These are full spectrum tinctures and they come in a few different strengths.
How CBD Oil Quality and Safety Are Governed in the U.S.
The Food and Drug Administration (FDA) has said pretty clearly that a lot of products sold as CBD either have less CBD than they claim or they are mixed with things you would not want to take. Hemp derived CBD with less than 0.3 percent THC is legal under the 2018 Farm Bill, but the FDA does not approve CBD oils the way they approve medicines. So companies handle things in different ways. Some take safety seriously, some do not.
That is why the certificate of analysis (COA) matters. It is a lab report from a third party. A good one should show:
-
how much CBD and THC is really in the bottle
-
if there are other cannabinoids like CBG or CBC
-
if there are pesticides, metals, or solvents
-
tests for mold or bacteria
Some states like Oregon and Colorado have their own public databases too. But even if you are not in those states, any brand worth your money will show you their COAs.
Mary Jane’s Bakery Co makes full spectrum tinctures and they test them. You can look at the results and see what is inside before you take it.
What to Look for in the Best CBD Oil
When people ask how to pick CBD oil, here are a few things I usually bring up.
Potency is one. Full spectrum means you get CBD plus small amounts of THC and other compounds. Broad spectrum means no THC. Isolate means only CBD.
Then there is lab testing. If the company does not show lab results, I would not buy from them.
Extraction matters too. CO2 is considered clean. Ethanol can work if done properly.
Price per milligram (mg) is a big one. A small bottle might look cheaper but if you check the price per mg, sometimes the larger ones give better value.
You can also look at the carrier oil. MCT oil or hemp seed oil are common. Dark glass bottles help the oil last longer.
Reputation counts. I like to buy from companies with good feedback and fair return policies. Mary Jane’s Bakery Co fits in that category.

How to Calculate Value: Price Per mg of CBD
One way to compare oils is to check the cost per mg.
Formula: Price ÷ Total mg CBD = Cost per mg
Example with the 1,000 mg tincture:
Price is 125 dollars. Divide 125 by 1,000. That comes to about 0.125 per mg.
This makes it easier to see which size gives more for your money. Bigger bottles usually come out cheaper per mg.
Safety Tips, Side Effects and When to Ask a Doctor
CBD is usually safe but there are a few things to keep in mind. Some people feel tired after taking it. Some get dry mouth or an upset stomach.
The bigger concern is how it mixes with other medicines. CBD is processed in the liver and it can interfere with certain drugs. If you take prescriptions, or if you are pregnant or breastfeeding, you should talk to a doctor first.
And of course, always read the COA before you take any oil.
How to Use and Dose CBD Oil Safely
Start with a small amount. Something like 5 to 10 mg a day is common. Then you can raise it slowly if you feel you need more.
Some people like to split their dose into a few smaller ones during the day.
The usual way is to hold the oil under your tongue for half a minute before swallowing. You can also mix it with food if you prefer.
Keep the bottle in a cool dark place with the lid closed tight.
