美國保健品也要好好甄別——CELLFOOD

最近一朋友在國內買了美國的保健品CELLFOOD，每瓶475元，以箱為單位賣，每箱5700元。說是能治癡呆症，恢複腦功能，抗癌，肺心病，心髒病糖尿病足等等。但服後感到不象所說的那樣神奇，想了解此保健品的真相。

我搜索了consumerLab.com, 得到的答案卻是否定的，所以美國的保健品也得好好甄別。

Question:
What is CELLFOOD and is it a healthy supplement?

Answer:
CELLFOOD^® (NuScience Corporation) is marketed as an "oxygen+nutrient supplement" for body detoxification, providing bioavailable oxygen to the body. However, the concept of ingesting oxygen is nonsense.  Oxygen is certainly good and necessary, however, the most effective method to get oxygen our tissues and muscles is breathing.  Ingesting oxygen will not enhance this process (Wing, Wilderness Environ Med 2003). In August, 2013, a retailer of CELLFOOD was warned by the U.S. FDA about drug claims it made in marketing CELLFOOd, as well as for violations of Good Manufacturing Practices in its handling of CELLFOOD. The Federal Trade Commission (FTC) has previously cited companies for marketing oxygen-containing supplements for treating cancer, heart disease, and others (Federal Trade Commission 1999).   

According to a website that sells CELLFOOD, it contains a proprietary blend containing purified water, dissolved oxygen, seawater extract, an amino acid blend, and enzyme blend.  The manufacturer further indicates that the product contains 78 minerals, 34 enzymes, and 17 amino acids.  Although this may all sound good and healthy, the specific amounts of these ingredients are not provided.  It's generally not a good idea to take a product that doesn't give specific amounts of each ingredient because the amount could be ineffectual or even unsafe.

Another concern with CELLFOOD is that, according to literature cited by the manufacturer, its contains deuterium sulfate.  Another name for deuterium sulfate is sulfuric acid-D2, which may be similar to the sulfuric acid contained in drain cleaners.  Even though the instructions indicate that you are supposed to dilute several drops of CELLFOOD in a cup of water, it's disconcerting to think that the product may contain an undisclosed amount of sulfuric acid.

 

CELLFOOD is also promoted for improving athletic performance, fibromyalgia, weight loss, cancer, and for general health. There seems to be little evidence supporting this. The company cites a small study in women with fibromyalgia which suggests that CELLFOOD might reduce symptoms (Nieddu, Reumatismo 2007).  However, due to poor study quality, these findings are not very reliable. The company also cites test tube studies showing  that CELLFOOD has antioxidant properties in different types of cells (Ferrero, J Physiol Pharmacol 2011; Benedetti, Food Chem Toxicol 2011).  Unfortunately, antioxidant effects on cells in laboratories don't necessarily translate into beneficial effects in humans.

The Bottom Line:
There appears to be no reliable evidence that CELLFOOD is beneficial for any use.
