L-Arginine supplements are available in a variety of forms, ranging from powders that are dissolved in water to capsules that are taken orally. The first step is to determine for what purpose you are taking the supplement. There are products that are designed as dietary supplements for general health purposes and those that are indicated for use for use by bodybuilders and other athletes. Make sure you choose the one that is appropriate for your needs, to ensure that you would get the benefits that you want.
The second step is to determine how much L-Arginine you are getting per dose. Each product contains a certain amount of the amino acid, whether it is per scoop or per capsule. Choose the one that will give you the amount of L-Arginine that you need. You can research this information by reading reviews or, better yet, looking at the labels of particular products.
Another consideration is the formulation of the supplement. L-Arginine supplements usually contain other ingredients that have their own health benefits. You should determine what these are and if they can provide you with the benefits that you want. However, L-Arginine should always be the main ingredient and make up the highest percentage of the formulation.
You should also make sure that you buy only from trustworthy manufacturers. You can do some research to determine which companies have a good reputation and sell a high quality product. In general, you should only deal with those manufacturers that are based in the US and avoid products from countries such as Mexico and China, since these are not only unregulated by any reputable agency but may also sell adulterated products. One indicator that the product comes from these countries is if the label contains many grammatical errors that indicate that the writer is not a native English speaker.
Of course, this does not mean that manufacturers in the US are automatically trustworthy, but they are subject to more oversight by agencies such as the FDA even if they are not directly regulated. In fact, the FDA maintains a list of “Tainted Products” which it updates regularly and lists dietary supplements it has tested and found to be potentially hazardous due to having hidden ingredients not listed on the label. There are also private consumer watchdogs whose websites you can consult about particular products, such as ConsumerLab, which test supplements and produce reviews of health supplements and nutritional products.
Another warning sign is if the price of the product is too low relative to others on the market.These prices may be “too good to be true” precisely because they are, since the manufacturers may be using low-quality ingredients or the supplement does not actually contain the amount of L-Arginine and other ingredients as stated on the label. At worst, they may be actively harmful since they are not tested for quality and may be adulterated.
When reading reviews of supplements, it can be easy to get caught up in the hype. Try to look past the exaggerations of reviews and look for hard information about the product. This will ensure that you get your money’s worth and that you choose the product that is right for your needs.
