Absolutely FANTASTIC product.
I was under a lot of stress and lack of sleep and started getting chest pains and irregular heartbeats. Within 3-4 days on this product all symptoms went away.
If you care for your heart and need extra strong and fast acting product, this is by far the best option to get your Q10 levels up.
HIGHLY RECOMMENDED. After the bottle I went back to regular ubiquinol (from Costco) supplementation to make sure this never happens again (I stopped for 6 months, but I really should not have). However I tried Costco first and did not get result when I was feeling real bad - so this one is A LOT more effective.
Product looks good in terms of both packaging and quality. Just started taking it for two weeks together with my other supplements, so far no visible difference ... will continue to monitor and see if it does make a difference.
