I was skeptical about Nutraharmony's PQQ supplement at first, but I decided to give it a try after reading about the benefits of mitochondrial health. After a month, I’ve noticed a boost in both my physical and mental energy. It’s also great knowing it’s made in the USA and lab-tested for purity.

I took this for a week to relieve joint pain. I have torn rotator cuffs in both shoulders, but not bad enough for surgery. I was taking Celebrex until it started messing with my kidneys. I have never had so much shoulder pain as I did while taking COQ10. I even started having knuckle pain in one of my hands. I quit taking it and the pain went away.

I started Pure Encapsulations multivitamin that contains CoQ10. I was feeling fine but was looking to start a good multivitamin that doesn’t have a lot of fillers or binders. I only took one yesterday morning and have been up all night. I’m super-hyper, having palpitations, and tingling in my legs, feet, and hands. I know CoQ10 is the culprit because all the other ingredients are vitamins and minerals. It’s a low dose of 50 mg. I had the same experience with CoQ10 years ago with a higher dose and... figured I would be okay with the lower dose in this multivitamin. I take nothing else, because I’m pretty healthy and active. I’m taking these back to Vitamin Shoppe for a refund. Read More Read Less

Condition: Fatigue

I began taking Nutraharmony's CoQ10 as part of my daily routine, with a dosage of 200mg per day. Initially, I wasn't sure what to expect, but within a few weeks, I noticed a significant difference in my energy levels and overall vitality. One of the most noticeable improvements was in my workout performance. I also had more endurance and stamina during my workouts. This allowed me to push myself further and achieve better results without feeling overly tired afterward. Moreover, I noticed an overall... sense of well-being and mental clarity. Tasks that once felt daunting now seemed more manageable, and I felt sharper and more focused throughout the day. Read More Read Less

Condition: Fibromyalgia

I started taking CoQ10 because I was having severe cramps and pain with taking statins. After a week of taking it the cramps started to lessen and over the next few weeks the side effects from statins almost disappeared.The other effect was that it helped lessen my pain from fibromyalgia. I take 150mg with fish oil twice a day.

WebMD states that CoQ10 is ineffective for treating diabetes. Google 'coq10 insulin response' and see how many studies from reputable sources state that it is. It works for me. BGLs are significantly lower. 200mg/day split in two doses. Of course, YMMV.

Condition: Fatigue

I was taking CoQ10 for 2 weeks + exercise, and since then I developed severe insomnia. My insomnia still lasts for an full YEAR. Its better now after year, but im not still like before.

71 yo female that was just feeling worn out. No energy, poor sleep, restless legs, etc. A retired nurse mentioned COQ10 because I have been on statins for many years. I feel like POPEYE with his can of spinach!! I have felt better, more energized, and therefore more positive, than I have felt in along time. Hope this benefit continues, but if not, I am thankful for however long it lasts.

Condition: Migraine headache

Been taking for over two months Jamieson Brand 250mg. Excellent for migraines, I do not get them anymore. Only thing I will say is, I had trouble getting to sleep if I took them before bed. Problem solved and recommend taking them first thing when you get up in morning.

When I first tried CoQ10, it did nothing for me. Then, researchng it further, I learned that it must be taken with oil. I tried again, and bingo! It worked. But even after all these years, doctors still do not usually tell you to take it with oil, and even the bottle (Now brand) only says to take if with food. So be aware! Your body needs the oil (olive oil, fish oil, or other kinds) to make CoQ10 work. That made all the difference for me.

Condition: Diabetic neuropathy

Took one 100mg capsule and did a workout. Found i had increase of strength and stamina. Increased my hunger, my energy throughout the day so much that it was like doing cocaine. Seemed as the day got later i got more and more hyper. I havent been able to find anyone with this same experience so maybe i have an allergy or some sort of sensitivity. I will not continue use.
