    Product Info

    About This Product

    • Supports cardiovascular health
    • Promotes nitric oxide production
    • Suitable for everyday wellness seekers
    • Free of gluten, dairy, soy, and nuts

    L-arginine is a free-form amino acid that your body converts into a chemical called nitric oxide. Nitric oxide is a vasodilator that promotes the relaxation of blood vessels, circulation, and heart health. While l-arginine is found naturally in red meats, chicken, fish, and dairy, sometimes our diet alone misses the mark. But don't worry, we're here to help.

    Taken once daily, The Vitamin Shoppe® brand L-Arginine capsules support cardiovascular health and nitric oxide production with 500mg of l-arginine per daily serving.

    Directions

    As a dietary supplement, take one (1) capsule daily, preferably in between meals.

    Warning

    Consult your healthcare provider prior to use if you are pregnant, nursing, taking any medication or have any medical conditions.

    L-arginine
    I've bought this product many times and this last time the capsules just come apart in the bottle. Called customer service to see if they would replace them and they said no cause it is over 30 days, which sometimes I buy several bottles and don't use them until I need it. This bottle has an exp. date of APR 2016 so it should still be good and I keep it in a cabinet with all my meds and everyone of them is fine except for this one. Very disappointed with the vitamin shoppe with the L-arginine and their customer service. Would not recommend this brand, buy another one.

    Capsules are poorly made
    The capsules keep separating and spilling the contents. It is poorly made. I have had to throw away almost a third of the product.

    Did this product help improve erections?
    A shopperMay 19, 2014

    Best Answer:  In conjunction with a couple of other things, testosterone oil and secretegoge, it has been terrific. I don't have total confidence in it's efficacy by itself. It is, however, good for blood flow which helps in other areas (cardiovascular).

    Is this good for erectile disfunction?
    A shopperJan 7, 2015

    Best Answer:  After taking the product for a while, I noticed a spike in my sexual activity. I can't say that L-Arginine was the reason, but it sure helped! That along with garlic, exercise and changing my diet.

    Is it ok to take it if you are also taking COQ10 daily?
    A shopperMay 21, 2016

    Best Answer:  Yes, you may take both. You should take the COQ10 right before or immediately after your first meal of the day. L-Arginine should be taken between meals: 2 hours after a meal and/or 2 hours before a meal. I also know that some people take their COQ10 at bed time: your preference.

    I have heard through the grapevine that this product can help with hair growth as well. Any truth to that?
    David DDec 31, 2013

    Best Answer:  L-Arginine is one of the essential amino acids used biologically to assist in many functions of the human body. Google the following: l-arginine biological effects and click on Pharmacodynamics of l-argining.
    I have been taking l-arginine for probably three years for the main purpose of helping to increase the NO (nitrous Oxide) concentration levels in the blood system. This combined with two other supplements helps to keep the intimate parts of life alive. As far as helping with hair growth, personally haven't heard or read anything about that, but being an essential amino acid it sure wouldn't hurt any thing. I have used Biotin to some benefit with hair loss. You might want to try that. Hope this helps you answer your question. Ken

    can you tell me what other supplements you take along with L arginine to keep the "intimate parts" working?arcas

    Is this product made up of acetyl L-carnitine (ALC) or propionyl-L-carnitine (PLC)?
    STEPHEN BFeb 21, 2013

    Best Answer:  Proprionyl-L-carnitine is a carnitine derivative. Acetyl-L-carnitine is, also a carnitine derivative. I have done some extensive search to try to see if L-argenine and any carnitine are related, and have foundnone. Dr. Weil writes about acetyl-L-carnitine"It is synthasized to provide a more bioavailable form of L-carnitine, which is a derivative of the amino acid lysine.
