Centrum Protegra contains: Vitamin A, Beta-Carotene, Vitamin E, Vitamin C, Folic Acid, Vitamin B1, Vitamin B2, Niacin, Vitamin B6, Vitamin B12, Vitamin D, Biotin, Pantothenic Acid, Calcium, Phosphorus, Iodine, iron, Magnesium, Copper, Manganese, Potassium, Chlorine, Chromium, Molybednum, Selenium, Zinc, Nickel, Tin, Vanadium, Silicon, and Lutein.

Mention vitamin C and most people will think of a tall glass of orange juice. However, the orange isn’t the only fruit rich in this vitamin. Berries, papaya, mango, watermelon, and kiwi are also excellent sources, as are vegetables like leafy greens.

Vitamin C is essential for the growth and repair of tissues in all parts of the body. It is involved in the formation of collagen, an important protein that is used to maintain healthy skin, scar tissue, tendons, ligaments, and blood vessels. Vitamin C also supports the healing of wounds, and for the repair and maintenance of cartilage, bones, and teeth. Like vitamins A and E, it also functions as an antioxidant, protecting the body from free radical damage.

As previously discussed, Centrum Protegra was recently reformulated in order to reflect recent findings regarding niacin. Unfortunately, the website does not reveal exactly what these findings were, or whether the levels of niacin in this formula were increased or reduced. In general, we prefer manufactures that post important scientific information prominently on their website so that consumers can make an informed decision.

In addition, Protegra also contains extra vitamin C and E, as well as more folic acid, vitamin B6, vitamin B12 and magnesium than other products in the Centrum line. Although the product description claims that this is a “high potency” formula, we were disappointed to find that it does not contain an absorption-enhancing ingredient such as 2-AEP.

• Fairly affordable at $16.99 for a 40-day supply
• Website posts a complete list of ingredients

• Website does not post testimonials
• No free trial sample available
• Does not contain 2-AEP

Consumers may be quite surprised to learn that the body sometimes never absorbs 85% of the vitamins and minerals in the average supplement, and simply pass through unutilized. However, the advanced ingredient 2-AEP has been shown to increase the absorption rate of nutrients by as much as 800%. This is quite a compelling reason to look for a supplement that contains absorption enhancers. In order to feel completely confident, consumers may want to look for a product that posts testimonials and offers free trial samples. This will allow them to see whether or not it suits their lifestyle before making a firm commitment.
