Barley grass is not the same as wheat grass. Indeed a whole book is devoted to the differences between the two. A notable difference I'd like to mention is: if you consume an amount of wheat grass juice that will make you throw up, the same amount of barley grass juice will not. So obviously, they are not the same. If you want more specifics, they're here.
I have used the recommendation of this product in my practice with great success, and there are hard science reasons for this, and the empirical evidence can't be argued with (well, it can be, usually by people who don't want to believe that we need to take a nutritional supplement).
Note: Daily Green Boost is great at helping to provide a wide variety of nutrients, but there's one "problematic" nutrient that even a great dietary nutritional complement like Daily Green Boost falls short in (and this is because this nutrient is not a vitamin or mineral).
NOTE: I'm providing these links below as a service; I do not make any money from you purchasing this product. And I believe in doing business with good companies that deserve our dollars, and the company that sells this product is one of these companies.
By the way, kids love it too, and kids are the toughest critics of all.
Q: Why is it recommended not to refrigerate it?
A: It can be stored in the freezer, but should be brought down to room temperature before opening, and then not kept in the refrigerator after it's been opened. The reason for not keeping it in the refrigerator after it has been opened and while you are using it is because the bottle will get cold, and then when you take the bottle out of the refrigerator into a warmer room where there is humidity, when you open the bottle, warm moist air will enter the bottle and the coldness of the glass will cause the water in that air to condense out into the bottle, getting the powder wet. And then you close the bottle back up. This is why it should be kept in a cool place in the room so it stays at room temperature, so the powder stays dry. But you can store multiple bottles in the freezer to preserve their freshness, just be sure to let the bottle acclimate a day at room temperature before opening.
Q: Regarding Barley Juice Powder - what makes Daily Green Boost better then something like the organic Bioglan one posted below?
A: There's 3 parts to my answer. 1) "More is not necessarily better". Daily Green Boost has only barley grass juice, Holland's Green Boost has a few things in it that I wouldn't put into my body, but having been an supplement industry insider, I know why they do this... because there are many people who think "more is better". Kale is a cruciferous veggie, and all cruciferous veggies inhibit iodine utilization. And many people are already iodine insufficient, so eating cruciferous veggies creates the "perfect storm" for an iodine deficiency. And of the grasses, barley is best to use to consume the juice of, and wheat is the worst. Whole books have been written comparing wheat grass juice and barley grass juice, with all the supporting science, and barley wins. Did you know that there's an amount of wheat grass juice that you can drink that will make you throw up, but if you drink that same amount of barley grass juice, you don't. Even more than that and you don't. That's a "biological clue", and I'm always on the lookout for those.
2) The nutrients in a product like this are only as good as the drying process allows them to be. Too high a temp, and wave bye-bye to the vitamins. The hands down best drying/powderizing process is the cold CO2 drying process. And if a product uses this more expensive process, they tout it in their promotional literature, like Daily Green Boost does. Holland's Green Boost makes no mention of their drying process. These kinds of products are not used by the gen pop, they are used by people who are more aware of health enhancing products, and they are more educated about things like drying processes. So to not mention their drying process is a red flag. Daily Green Boost can truthfully say it's raw. So, all vitamins intact.
3) While sea-based foods like spirulina and chlorella should be fine to add, they're not always. It depends how "clean" they are, and unlike land-based foods, sea-based foods now-a-days can contain toxins like PCBs. That's why, unless you can couch for the source, it's best to stay away from them. Plus, they don't offer anything that land-based plant foods can't (if those land-plant foods are grown in kick-butt soil). Not even iodine.
I could go on, but I'd bore you to tears. But if all you can get is Holland's product, it might be better than nothing added. But if you can get Daily Green Boost, even if it's more money due to shipping, it would be a better investment in your future health.
