Full Spectrum Avena Sativa (Green Oat Grass) is rated 4.7 out of 5 by 17.
Rated 5 out of 5 by from Green Oat Grass! I took a chewable form of avena sativa years ago and could not find the same product but was pleased to find this supplement at Swanson Vitamins. It's a nice little pick me up and I have read of many health benefits of green oat grass. The twice a day or as needed dosage works for me! Thank you, Swanson, for providing this quality supplement at such an affordable price! Kentucky

Rated 5 out of 5 by from avena Oat straw is good for what it is acclaimed. As for the additives such as magnesium stearate or silica, I have my douts about it.

Rated 5 out of 5 by from best energy product ever I heard of this product on Dr. Oz TV. The 2nd dose improved my energy noticeably. I take 2 in the am and I seldom run out of steam. I'm almost 68 and I want to do everything I used to do when I was young. I'm glad Swanson sends my supply every month and at a great price! TY Swanson.

Rated 4 out of 5 by from libido Bought 6 libido & energy enhancers from swanson's recently. I have taken this separately and it seems to stand out in energy and in the bedroom. Try it you may get great results too.

Rated 4 out of 5 by from decent energy supplement This product does help with energy in the morning. After a few hours, I feel completely energized and ready to take on the day. My only criticism is that the supplement does not act quickly. It takes a couple hours for the benefits to set in before you notice any changes. I wish that Swanson would be able to make a fast release form of this supplement. I think it would vastly improve the product since avena sativa mainly helps with that morning energy boost.

Rated 5 out of 5 by from Great for strong nails This is essentially oat straw. the technical name is avena sativa & it's loaded with siica. seems to have more than even the silica liquid. I started taking this for my skin but noticed a bigger difference in the strength of my nails. I can't remember the last time my nails were this strong. This is a great value & really works.
