Because the safest and most effective dose of L-arginine has not yet been established, it is a good idea to follow the directions on the label of your particular product. The research on L-arginine is still in its early stages, which is why there are no clearly defined dosing guidelines. It is also a good idea to check with your pharmacist about which manufacturers are reputable.
The best dose of L-arginine has not yet been determined for most uses. Research on the product is still in its early stages, so it is too early to recommend dosages that are both safe and effective. Also, people may have varying degrees of L-arginine needs and levels of deficiencies, and what may be best for one person may not be right for another.
Studies have used a wide range of L-arginine dosages, from as low as 500 mg per day for some conditions up to 2000 mg per day for others. The best dose has not yet been clearly established for any use. It is reasonable to follow the directions on the label of your particular L-arginine product. Do not exceed these dosing recommendations unless your healthcare provider specifically tells you to.
Some considerations to keep in mind when taking L-arginine include the following:
- Because the manufacturing of dietary supplements is not closely regulated, it is important to choose a trustworthy manufacturer of your L-arginine supplements. It is a good idea to look for the "USP" symbol, as this means that the supplement has been tested and contains the right ingredients in the right amounts.
- There is a large variation in the cost of L-arginine supplements, from relatively inexpensive to very expensive. Price is not always an indication of quality. Your pharmacist is a good source of information about which supplement manufacturers are more reputable and trustworthy.
- If you have any chronic health problems or take any prescription medications, it is a good idea to check with your healthcare provider before taking L-arginine.
- If you are unsure about anything related to your dosage or L-arginine dosing in general, talk with your healthcare provider or pharmacist.
