Iron is one of the most abundant metals on Earth and is essential to most life forms, including humans. Iron is an integral part of many proteins, particularly those involved in oxygen transport. Almost two-thirds of the iron in the body is found in the red blood cells that carry oxygen to tissues.

Iron can be found in a number of food sources, including red meat, fish, and poultry. It can also be found in lentils, beans, and other legumes, as well as in spinach and whole grains. Supplemental iron is particularly important for virtually all premenopausal woman, including teenagers and pregnant. It is reported that, men and postmenopausal women should avoid supplemental iron because it could put them at an increased risk for heart disease and liver failure.

As previously discussed, Just Once is likely to appeal to consumers who are looking for a one-a-day multivitamin. This kind of supplement is particularly popular among individuals who report having difficulty remembering to take their vitamins, and therefore want the simplest product available. Unfortunately, one pill may not fill the average adult’s complete nutritional needs. Consumers may instead want to consider a combination regimen consisting of several concentrated vitamin and mineral formulas. For maximum convenience, some manufacturers offer pre-packaged single servings.

• Fairly affordable at $12.95 for a 30-day supply
• Website posts a complete list of ingredients

• No free trial sample available
• Website does not post testimonials
• Formula does not contain an advanced ingredient to maximize absorption

If Just Once contains all of the nutrients that a person needs each day, one can’t help but wonder why Rainbow Light manufactures an additional 10 multivitamin formulas. By not providing specific scientific information about its products, this company makes it incredibly difficult for consumers to determine whether or not a particular product is right for them. For this reason, we highly recommend that consumers look for manufacturers that post testimonials prominently on their website. These unsolicited letters of praise not only provide concrete evidence of a particular product’s effectiveness, but they also provide insight into the company’s commitment to customer service.
