NuvoSoma Labs L-Arginine 5000mg Cardio Power Dietary Supplement includes Nitric Oxide, L-citrulline, CoQ10 and Resveratrol

I rarely rate things harshly, but I'm doing so in this case for a very specific reason.First, I am a medical doctor who takes a lot of supplements and recommends them to others. But I am torn about this product. The list of ingredients is fine although some of them should not be taken together, so their effect may be negated (not a big problem). And the flavor is fine for an arginine supplement. But this company doesn't seem to exist. I've looked up their website and the only thing on it is their logo. There is no address or phone number to contact them on the website or on the product, and this is very important for any supplement company. I find this disturbing and so should all of you. I'd like to see the laboratory tests that verify the ingredients and their purity when I'm putting something in my body, and so far I have no way of doing that with this product.So, if anyone knows of a lab that has tested this product, I'd appreciate a heads up. It's impossible to judge any supplement on how you feel while taking it. The placebo effect is difficult to discount in things like this.If anyone from this company reads the comments here, please post some contact information and the results of testing of the product, if you have it. Because at this price and with this list of ingredients, if the product contains what you say it does, you'll corner the market in short order.Addendum 1/7/2015 - Returned the product and received a call from Rob, the owner of the company. He was very helpful and explained, as he did in his comment under my review, that the website was behind schedule but that the answers to my questions were there. He explained the rationale behind the product and explained that the website, although behind, would be up soon. And as you can see, he posted the FAQs from the future website. I look forward to the website being operational and am changing my original two stars to four stars. Why four stars? Because there is a problem taking, for instance, Vitamin D3 on an empty stomach. It is fat soluble and needs some fat to be well absorbed (a major problem with Vit D preparations) while Arginine needs to be taken on an empty stomach to be well absorbed. But even with small quibbles such as these, this product seems to give users the arginine they need at a price point that will be below market. So, I wish them good luck with it and think it will do very well.

So now I'm very concerned at whats going on. Before this product I was using a similar product purchase here on Amazon L-Arginine-X and the seller as well as the product dropped out of existence!Now this product is no longer offered for sale, and the sellers website is down. Is there some issue with these products?Comments anyone? Comments AMAZON?ORIGINAL REVIEW===============This is the second product of this type that I've tried and so far it's a keeper.What I particularly like about it is that there seems to be very little added sweetener/artificial sweetener, in contrast to competing products. Anyone who's serious about taking something like this for their health would not want any real or fake sugars added.It's a very fine powder and I have not seen any clumping so far. Also dissolves well - I hope the makers did not have to make any significant sacrifices to get it to be like this - I'd rather a little inconvenience for a better or cleaner product.The powder is so fine, in fact, you have to be careful when pouring it to avoid some of it going airborne - I have had an unexpected whiff or two of it.Please keep up the good work and whatever you do don't compromise the quality!

I used this product all of the time and until now it has been a Five Star rating...For some reason like all companies they start cutting back on what makes the product great. It has less effect than my past product purchases. It never fails this is not the same product of two months ago.. these companies have no clue of what the consumer can detect when a product is changed. It's very obvious. This collusion is a dishonest rouge agenda and quite frankly it is BULL!

I've been using this product for about two weeks now and feel a big difference in my performance at the gym. I also wear an Elevation training mask when I'm doing cardio and I Hardly take it off. When I do a super set in the gym, I’m not breathing hard. I don’t rate that much because I don’t have that much time. But this stuff works. I’m ordering two more..

I heard about the great benefits of L-Arginie, and had gotten some pills, but they were huge and I had trouble taking them. I found the L-Arginine Cardio powder and read the ingredients and the reviews. I loved that it had no sugar or artificial sweeteners, and had a flavor I might like. It came quickly, and I've been very impressed. It tastes good, and really helps me get through my workouts. My stamina is better, and I hope it improves even more. So far so good, and I'll continue to use it.

I bought this product for my 74 year old mom because it seem to have a lot of what her doctor was recommending. However, once I showed it to the doctor, she said it was not a good supplement because it contains folic acid, which is a synthetic form of vitamin B that half of adults cannot convert to the bio active form that would actually benefit the body. That aside, I didn't really see any improvement in my mom. Her blood pressure remained high. She didn't have more mental clarity. At some point she actually started having a hard time falling asleep. I'm really surprised with the results. I had such high hopes for this product. Perhaps if they swapped out Folic acid with Folate or Folinic Acid that would help. Increasing the L Citrulline to 1000mg might help as well.

Like the taste and overall the product is good. But it does need more L-Citriline to be effective. 200 mg is not enough. If it had 1000mg I would buy again because I like the taste better than the other brands.

I was looking for a solid l arginine product to add to my supplementation to combat adrenal fatigue. L arginine Cardio Power is definitely functional. I didn't think too much about any sexual health benefits, but to my surprise and my wife's delight they are there.
