This is my favorite Alfalfa option because of the grain content, which also is at a great price on iHerb. Often with previous brands a "serving" required taking a handful of alfalfa, which the kids didn't enjoy. Yet, these tablets are small enough even our elementary age kids could swallow them. These are an effective option to help with recurring sinus congestion, as sometimes evidenced by the puffy eyes, or general fluid retention. By comparison, we previously used Source Naturals, whose 10 grain, 6 tablet serving only included 3.89 g of Alfalfa versus Nature's Plus 1 tablet, 8.5 grain serving providing 550.8 mg.
