Dr. MercolaL-Arginine Advanced, 30 Servings (90 Capsules), 1,000 mg Per Serving, Dietary Supplement, Supports Energy Production, Non-GMO

All of Mercola products are great! This supplement helps to maintain healthy skin. Great product.

Excellent product. Improves circulation. I trust all Mercola products because of their quality ingredients.

Dr. Mercola L-Argine Advanced came in a 90-count bottle and with a serving of 3 capsules each, will last one about a month. Three capsules contain 1,000 mg of l-arginine and are unique in that they resemble old fashioned pills with their transparent plastic coating and the beaded ingredients inside. I found them quite easy to swallow.I've used arginine in the past as a pre-workout for energy and muscle pump and while it is not as quickly effective and made readily available in the body as other nitric oxide products such as l-citrulline or beet root, it is good as a slower release formula for the long haul. I do like the fact it is pure arginine since so many other products that contain it, add a lot of other unnecessary ingredients, as well as the fact it is double the milligrams of most of manufacturers.If you want to give yourself an edge in your workouts, I recommend this product.

Very convenient L-Arginine pills. I use these for GH-boosting prior to sleep. Really like that L-Leucine is included in the formula, as I find that prevents excessive Nitric Oxide production, which for me is an unpleasant effect of L-Arginine I'm not looking for (though it is another reason some people supplement with it).

This supplement offers a potent and sustainable solution for supporting energy production. Being a non-GMO product adds to its appeal, aligning with my commitment to quality and natural ingredients. I've experienced a noticeable increase in energy levels and stamina since incorporating this dietary supplement into my routine. Dr. Mercola's commitment to excellence is evident in this L-Arginine formula, making it a trusted choice for anyone seeking a reliable and effective energy boost. I highly recommend Dr. Mercola L-Arginine Advanced for its quality, potency, and overall positive impact on energy and vitality.

i've been following Dr. Mercola for 15+ years, listening to his podcasts as well as reading his newsletters. as far as i'm concerned, he's the leading authority on longevity research and is a person i deeply trust. his supplement products are therefore well-researched and well-sourced. if a particular supplement is of use to you, you can't do much better than Dr. Mercola.i'm not going to get into the potential benefits of L-Arginine, you can research that yourself. know, however that it is an integral part of my supplement stack that i take every day and have been taking for many many years. the product here is 90 capsules, but the 1000mg serving (which is standard for this amino) is achieved by taking 3 caps, meaning this is a 30 day supply. other L-Arginine caps i've taken have gone the single, massive horse-pill sized route. i GREATLY prefer the size of these caps. easy to swallow, easy to digest and from one of the most trusted names i'm aware of. easy 5 stars...

I found this supplement to be mostly clean and effective. My one suggestion or concern is the tapioca starch. Tapioca starch isn't a good option for keto. This food additive is high in net carbs and contains no fat or protein. Tapioca starch has almost no nutritional value, so it only increases your calorie intake. Even small amounts will kick you out of ketosis.

This seems to be a good quality supplement. The capsules are clear and inside are lots of tiny pellets which should mean that the L-Arginine absorbs faster than a hard pill. One serving size is actually three capsules, which totals 1,000 mg of L-Arginine. I personally can’t take these on an empty stomach, otherwise I get a little queasy. There are no weird odors or taste to the capsules.Edit: I found out the hard way that L-Arginine may cause canker sores. I am genetically prone to getting them, but I finally was doing well after discovering Borax Homeopathic keeps them from developing into a big sore. I had gone two years without getting a full-blown canker sore, but a month after I started taking this supplement, I got the worst canker sore of my life that lasted for over a week. After researching triggers, I read that L-Arginine can make it worse or cause the sores. So if you are prone to canker sores, do not try this.
