To date, the products that have been examined in all of the studies were Garden Blend and Orchard Blend (2 capsules of each taken daily in most of the studies), with the exception of one study on Vineyard Blend taken in combination with Garden and Orchard Blend (Plotnick et al. J Am Coll Cardiol 2003;41:1744-9), and one study on Juice Plus Gummies (Stewart et al. J Am Diet Assoc. 2002;102:1652-7).
