Is L-Arginine Safe?
Thank you for thinking of safety. Before you begin any type of nutrient supplementation program, safety should be fully considered. Fortunately, L-Arginine is well studied; it is also present in virtually all foods. The following questions and answers are constructed to assist you in making a determination if L-Arginine supplementation may be beneficial and safe for you.
Are there any major side effects of L-Arginine?
There are some clinical side effects of L-Arginine which makes it unsuitable for ingestion by pregnant or nursing women. In addition to that, people suffering from low blood pressure should not take L-Arginine without consulting their doctor as their blood pressure may drop further. Those people with a medical history of kidney or liver disease should not use an L-Arginine supplement as it may alter potassium levels in the body. Other reported side effects of taking an L-Arginine product include allergic reactions, respiratory problems, and herpes simplex (cold sores) outbreaks.
Should I ask my Doctor about Embla Arginine?
Yes. We hope that you both ask him/her and tell him/her about Embla Arginine. We want the medical profession to know about Embla Arginine and we want you to make a good choice for your health and wellness. It is always best before beginning any supplement to consult with your doctor, especially if you are taking any medications. If you have any questions or concerns, you should consult with your doctor. Remember, we do not know you or the status of your health. Your doctor does – or should! An increasing number of doctors are becoming more receptive to natural supplementation (At Last!) and especially L-Arginine. That doesn’t mean to say that they will condone its use as you need to remember that they carry a great deal of liability and a “no” may not be the correct answer. You should make your own choice and do your own research. We know that L-Arginine, as shown by the 1998 Nobel Prize award, has many excellent benefits to health. It may have some side effects for you that others don’t experience.
How much L-Arginine can one safely consume, and within what time period?
The amino acid L-Arginine is found in most foods. So, the crux of the issue about L-Arginine safety is not whether L-Arginine is safe or not - it is safe to eat as proven by thousands of years of recorded history. The real question is whether L-Arginine consumption can be overdone.
The average American diet includes approximately 4 grams of L-Arginine per day. Numerous studies show that much more L-Arginine, up to 20 grams of daily L-Arginine consumption, improves the health of the majority of adults while still being considered a safe amount for daily consumption.
In determining how much L-Arginine would be wise for an individual to consume, an advisable course is to consult with your own health care professional since he or she knows you individually. We recommend that you continue to learn about L-Arginine and then discuss your healthcare options with your physician or other health care professional.
Are There Some People Who Should Not Supplement With L-Arginine?
While in general terms, L-Arginine supplementation for an average sized adult up to a rate of about 20 grams per day is beneficial, each and every person must determine (in consultation with his/her health care provider) if L-Arginine supplementation would be specifically beneficial to his/her body. There is risk inherent in being unique that cannot be addressed from a website or general recommendation.
Below are some guidelines as to who should not supplement with L-Arginine. These guidelines are not complete, so you must look to your personal health care provider for final recommendations.
- Again, one of the important things to remember in the field of physiology and nutrition is that people’s individual situations are unique and therefore consulting with one’s health professional who understands how to proceed in light of one’s unique situation is ALWAYS advisable.
- No one under the age of 23 should supplement with L-Arginine without the express approval by his/her health care professional since growth hormone levels could become too high.
- L-Arginine is a powerful, tissue growth accelerating nutrient. That means that L-Arginine supplementation could be very harmful for persons with cancer, for pregnant women and their gestating babies and for nursing babies.
- Persons with liver or kidney disease do not process foods nor dispose of metabolic byproducts in the same way or as efficiently as persons without such health challenges. Therefore, these persons must discuss the advisability of L-Arginine supplementation in their particular cases.
- Persons with viral diseases may already be unbalanced to the L-Arginine side, and additional L-Arginine would only serve to exacerbate viral activity. Persons with any type of herpes, and especially ocular or brain herpes, should not supplement with L-Arginine, except with the supervision and recommendation of one’s health professional.
Will L-Arginine Cause Free Radical Damage to the Body?
All foods result in free radical damage to the body. It is the nature of life that metabolism (extracting energy and nutrients from food) both nourishes our cells and damages our cells because free radical production is coincident to energy production.
Embla Arginine, however, has been designed to minimize free radical damage. It provides your body with powerful antioxidant properties (free radical combating properties) and cell membrane protecting properties to minimize free radical damage. In fact, by consuming Embla Arginine, less free radical damage will likely be occuring in your body than if you did not consume it.
L-Arginine versus Lysine Antagonism - What Does it Mean?
One of the issues regarding optimal L-Arginine consumption is that L-Arginine and Lysine are antagonists. That is, they compete for cell uptake. When competing for cell uptake, each of these amino acids prevents the other from penetrating cell membranes and being retained in the body. Thus when L-Arginine and Lysine reach the bloodstream at the same time, one does not receive the Nitric-Oxide benefits from L-Arginine nor the viral inhibiting benefits from the Lysine.
The trick, then, is to have L-Arginine and Lysine reach the blood stream at different times so that they are each individually utilized. Therefore, Lysine should only be consumed at least 20 minutes after L-Arginine is consumed to gain the benefits of both L-Arginine and Lysine.
