Can the coq10 be stored at 32 degrees

Short answer? No. Longer answer? Product advice for CoQ10, Heart Protector, Vitamin C, etc., etc., etc., is to "Store Product in a COOL place". 32 degrees F isn't 'cool'. Good luck. Stay healthy.

How many milligrams of nattokinase does this contain? 1000 IUs doesn’t tell me anything because I don’t know what standard of conversion is used.

Hi in terms of "FU" or fibrin units. This is entirely different from the IU measurement since it only indicates nattokinase activity base on the degradation of fibrin. But as of today, IU is being officially adopted by the Japanese when measuring nattokinase. The FU method doesn't have exact measure of nattokinase activity and is suspected to be erroneous. Because of that, IU standard is being used to accurately measure nattokinase. However, the FU measurement is still being widely used in labels. Most nattokinase supplements nowadays are in 100 mg capsule with 2,000 FU. Amazon Ranger

Heart Protector is best stored in a cool dry location, such as a cupboard or pantry. This formula does not contain any CoQ10.

Strong heart beat

Heart disease is the #1 killer for both men and women all around the world. With this unique supplement combined with a healthy lifestyle, I feel my heart beat much stronger. My heart rate gets above 180 at work for several hours and this allows me to push through tough days without struggle, but with relative ease, and my heart rate decreases quickly when im at rest. My lowest resting heart rate is 38 and average is around 41 at rest (sleeping). HRV ranges from 90-170ms. I haven't found another heart supplement like this one, my heart feels very strong and healthy. I love it, thank you Pure Synergy.

Will buy again

Relaxed my heart within 30 minutes of first use. It seems like it's working but would need to retake blood work to be certain. Just wish it was more affordable, but if it does whats listed then it's work the price.
