I've been taking Sundown Xtra for several years and have found it to be an excellent product. In order for folic acid to be effective in lowering homocysteine levels, it needs to be taken in conjunction with Vitamin 6 & 12, This product allows you to get the benefit of a maximum dose of folic acid (800mcg) and the necessary Vitamin B's ALL in ONE caplet. Much easier than having to buy folic acid and Vitamin B complex *separately* in order to properly augment. Although recent studies have questioned the relevance of homocysteine levels regarding cardiac health, I believe there's a great deal of merit in continuing to take folic acid. My homocysteine levels decreased substantially (from a 14 to an 8) after taking this folic acid/Vitamin B complex combination for six months. I would strongly recommend it. Wishing you all the best of health.
