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

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. Store in a cool, dry place. Keep out of reach of children. Tamper evident. Do not use if outer seal is broken or missing.

Makes me too hot
I think the whole tablet of 500mg is too much for me. I weight 170 pounds, and I think it's too much? It seems to raise my body temperature a lot, which, I guess, is an indicator that my circulation is better, but because it raises my body temperature so much, I can't sleep at night as my bed and sheets feel way too hot.
I think may be half the tablet might work, may be 200mg? But this whole tablet is too much, I guess.
Other than that, I don't feel much different. Just too darned hot. Probably means I don't really need it. I eat enough meat as is, and I am very healthy with no underlying problems.

COST LESS & OUTSTANDING PRODUCT!!
L-Arginine is an outstanding Product and hard to find in a large quantity for less money, so when I found it at The Vitamin Shoppe (TVS) I had to purchase it. The label recommends you take this product up to 2-times a day, and that adds up to a lot of vitamins and the only place I could find this product cheaper, larger quantity and quick availability was at TVS so I have ordered it to keep my cost down, and have one stop shopping. Highly recommend getting all your vitamins and supplements from TVS.
