  1. Miriam C

    I’m sure I’m not alone when it comes to women of a certain age. I’ve had trouble sleeping through the night for years but I’m NO fan of prescription medications or over the counter sleep aids. Feel like I’ve finally turned a corner. Thank you.

  2. Cara P

    I take a third of a dropper each morning and each night I put a little oil in my palm and smooth it over my face. I swear my complexion looks better than it has in years.

  3. Pete R

    I play a lot of golf and tennis and I was definitely feeling it the next day. Now I take a half dropper every night and wake up thinking my arms and legs are 10 years younger.

    Hard to believe for a 66 year old. There must be something about the power of plants after all.

  4. Darlene M

    I’ve suffered for years from arthritis in my hands. I rub the oil onto my knuckles at night and by the next morning I’m ready for action. Go figure.

  5. Derek W

    I had a nervous twitch in my right eye for a year. No matter how much sleep I got, that twitch was back the next day. After two weeks of Rational – Boom! Gone. I don’t care how this stuff works– I just know it does for me.

  6. Nicole

    I decided to go with the half size first to see how I liked it. Full strength and undiluted = Amazing Value. I take a quarter of a dropper daily and the 15ml lasted two months!

  7. Alex M

    I don’t know how to explain it. I wasn’t sick. I didn’t have any specific aches and pains. But my friends convinced me to try Rational and….I just feel better. All around healthier, more in balance….and just better.

  8. Amanda B

    I was a little put off by the taste. When they say Rational is pure and all natural — they mean it. But actually, after a few days I was totally used to it and really happy there wasn’t anything in there besides the hemp seed oil. As they say – it is what it is!

  9. Tammy F

    Customer service with this company is splendid. Nice people, smart answers. Same day shipping and it’s free.

  10. Henry T

    I run a pharmacy in Connecticut and I was carrying two national brands. Then Rational Hemp showed me how with an undiluted 2400mg brand like theirs my customers can just adjust their dose based on their needs. And Rational is priced much more competitively. Price and Quality. Guess what brand my wife and I use at home? Rational.

  11. Jim C

    I read a lot of articles about CBD when it first became legal. The thing that most appealed to me was that it could be an effective anti inflammatory. After a lifetime of marathons and triathlons, free radicals are a real enemy. There are many antioxidants but after a year of consistent use I believe CBD is the best.

  12. Sam S

    I didn’t understand the whole mg and ml thing with CBD and 600mg could be so expensive with one brand and 1000mg less expensive with another brand. It was just confounding. Rational makes it easy. They tell you how much they charge per mg – and that’s 4 cents. Every company should be doing that.

  13. Debbie D

    I have steel rods in my back and after using Rational for several months, I have weaned myself off opioids. I had real doubts that would ever happen. I used to get up every two hours and be groggy and out of it – and now I can almost sleep through an entire night. Thank you Rational.

  14. Chris M

    I am fortunately not challenged financially but I love that Rational is the most aggressive discounter of the highest quality product in the market. These guys are great.

  15. Anne G

    Friends told me CBD would solve my sleep issues. (I have the smartest friends!) One is so smart she recommended Rational. I fall asleep in 5 minutes now, not an hour or more — and the best part is when I wake up, I am ready to go.

  16. Terri D

    My car was rear ended almost a year ago, landing me in the ER and seriously straining my neck. The doctors wanted to give me muscle relaxants and pills for nerve pain. After two months of Rational I can sleep on my stomach again — not on my back staring up at the ceiling. I even rub some Rational on my shoulders before bed and the knots are gone in the morning. All I can say is that it has worked wonders for me.

  17. Porter F.

    Rational Hemp’s CBD oil has dramatically reduced/eliminated my lower back pain from a lifetime of high impact sports and heavy training cycles. Their price and purity allows me to take the proper dose and continue to enjoy life to its fullest.

  18. Sam T

    I bike 30 to 50k a day — and I wake up without soreness every morning.
