I’ve had to take PPIs (stomach acid reducers) for 27 years, and they are known to cause malabsorption of vitamins and other essential nutrients. That being said, I’ve felt progressively run-down and exhausted for the last 10-years. Within 5-days of starting Jarrow’s Arginine and their PQQ, I feel better than I have in years. I have so much more energy and my peri-menopause brain fog is gone. These are fairly large pills, but they do go down fairly easily. I cannot comment on how it has effected my bloodwork, as I’m going to wait 3-months first.

I purchased this to help improve vascular health. L-arginine according to health articles I have read should have some benefit to help with circulation, exercise and inflammation. This supplement is a good supplement to go along with positive dietary changes, and is of a good quality. The only downside is the pill is a little bit on the large size.

Products are of high quality, fast delivery, are the vitamins and minerals that the body needs daily or as recommended to eat. Impressed after using this online shopping service.

I have been regularly consuming Arginine by Jarrows for 3 years daily everyday without fail since 2017 and although i dont really feel much magical difference, i do believe it helps me much with the nitric oxide levels in my blood and veins to assist my bloodflow to my muscles during exercise as well as taking care of my heart

Arginine plays a key role in cell division. Accelerates the elimination of toxic ammonia from the body. Improves immune function. Stimulates the synthesis of growth hormones. Stimulates the accumulation of muscle mass. Inhibits fat accumulation and reduces the risk of heart disease. Helps lower blood pressure. My husband drinks it every day and recommends it.

L-arginine is good for my workout. I can lift heavy weights with this supplement. The ingredients and high quality is the best!

If you took a long time this amino acid you should take Lysine for balance

One of my favorites.good for circulation.works well relaxation veins. Gives you energy.

I take one tablet before working out or just after finished it. It’s good for your muscles.

This is an easy and convenient supplement product! Also the price is lovely.
