Chest pain

Posted by 5514864812497002227 on Aug 11, 2016

I had a chest pain on the first day that I took, but not so sure so I continued to took them for 1 week but felt the same. Anyone have the same symptom? Is it the side effect? Now I have decided to stop taking this until I find out...

Optimistically ordered a second bottle

Posted by ReaCovery on Nov 20, 2015

I bought this for my dad who is in his 80's. He has been on statins for a while, but stopped taking them because the side effects were ruining the quality of his life. He now wants to repair the damage done by those drugs and started with regular CoQ10, but now has switched to this form. His muscle pain has decreased since stopping the statins and staring the CoQ10. This form is better absorbed and you need to take less. He is now able to exercise more because of less pain, this is good for his health. He is using Kyolic garlic, diet and exercise to manage his cholesterol and blood pressure. His doctor keeps pushing drugs, but they make life miserable because of the side effects. Much better to try and improve health in more healthy, natural ways if possible. Drugs are small doses of poisons, can't be good for a body when taken long term.

Purchased for my Pekingese dog

Posted by Reviewer2822701 on Nov 15, 2015

I purchased this product for my 13 year old Pekingese, as he had an enlarged heart and murmur. He got to coughing and the vet told me he had heart disease. So I bought this and gave him 1/2 the gel in his evening meal. It did help him as he stopped coughing and it even made his gums pinker, as he some teeth problems which go hand in hand with heart disease. I t also seemed to give him more play time instead of sleep time, so his energy levels were a little bit better too. If you dog has heart issues check with your vet to see if supplementing with this will help them. They can recommend the proper dosage too.
