CoQ10

CoQ10 is also a vasodilator which improves heart function and circulation.

It is also an antioxidant.

The main reason I recommend it to endurance athletes is that it helps the body convert carbohydrates into energy. With correct dosage and timing of that dosage, CoQ10 has clinically proven to enhance stamina and endurance.

There are studies that show that a herb named "Hawthorn" can similarly improve cardiac function. The main effect of Hawthorn is it's function as a vasodilator. Essentially, it improves the blood flow to the heart muscle itself.

WARNING!

Do not use either of these suppliments if you are taking Warfarin ( a blood thinning medication usually prescribed to cardiac patients).

TIP!

Do not expect immediate results. It usually takes 3-6 weeks to nitice a marked improvement in cardiac function.

Do you have more information about the timing of taking CoQ10? Do you mean taking in pre-post workout or just every day with a meal?

Another interesting personal story about CoQ10.

I was a big fan of supplements for a long time. When I first came across CoQ10 (almost 20 years ago), it was nearly unknown to general public. One day, a friend at work (he was diagnosed with brain tumor and was undergoing chemotherapy at the time) asked for my advise regarding his nutrition and supplementation. I did some research and I suggested that he beef up his anti oxidant supplements and that he particularly increase his CoQ10. I read a research paper that CoQ10 strongly offsets immuno-depressive affects of certain chemo agents. My friend reported remarkable improvements. Eight years later, he was still around. I lost his track since but I hope CoQ10 saved his life.

Like any supplement, it should not be taken blindly. It works best when there is insufficiency. Being in heavy training phase does create elevated metabolic need for coQ10. I personally noticed lowered HR when CoQ10 was used in combination with L-Carnitine.

CoQ10 should be treated as vitamin and, if a user desides to use it, it's best to be taken regularly and with meals and plenty of liquids.

It's chemical action is to facilitate electron transfer at cellular level. Thus, it's a metabolic enhancer that supports prior Krebs cycle stages.
