"Darkness cannot be dissipated with more darkness.
Federal officials have received reports of 13 deaths over the last four years that cited the possible involvement of 5-Hour Energy, a highly caffeinated energy shot, according to Food and Drug Administration records and an interview with an agency official.

The disclosure of the reports is the second time in recent weeks that F.D.A. filings citing energy drinks and deaths have emerged. Last month, the agency acknowledged it had received five fatality filings mentioning another popular energy drink, Monster Energy.

Since 2009, 5-Hour Energy has been mentioned in some 90 filings with the F.D.A., including more than 30 that involved serious or life-threatening injuries like heart attacks, convulsions and, in one case, a spontaneous abortion, a summary of F.D.A. records reviewed by The New York Times showed.

The filing of an incident report with the F.D.A. does not mean that a product was responsible for a death or an injury or contributed in any way to it. Such reports can be fragmentary in nature and difficult to investigate.

The distributor of 5-Hour Energy, Living Essentials of Farmington Hills, Mich., did not respond to written questions about the filings, and its top executive declined to be interviewed. Living Essentials is a unit of the product’s producer, Innovation Ventures.

However, in a statement, Living Essentials said the product was safe when used as directed and that it was “unaware of any deaths proven to be caused by the consumption of 5-Hour Energy.”

Since the public disclosure of reports about Monster Energy, its producer, Monster Beverage of Corona, Calif., has repeatedly said that its products are safe, adding that they were not the cause of any of the health problems reported to the F.D.A.

Shares of Monster Beverage, which traded above $80 earlier this year, closed Wednesday at $44.74.

The fast-growing energy drink industry is facing increasing scrutiny over issues like labeling disclosures and possible health risks. Some lawmakers are calling on the F.D.A. to increase its regulation of the products and the New York State attorney general is investigating the practices of several producers.

Unlike Red Bull, Monster Energy and some other energy drinks that look like beverages, 5-Hour Energy is sold in a two-ounce bottle referred to as a shot. The company does not disclose the amount of caffeine in each bottle, but a recent article published by Consumer Reports placed that level at about 215 milligrams.

An eight-ounce cup of coffee, depending on how it is made, can contain from 100 to 150 milligrams of caffeine.

The F.D.A. has stated that it does not have sufficient scientific evidence to justify changing how it regulates caffeine or other ingredients in energy products. The issue of how to do so is complicated by the fact that some high-caffeine drinks, like Red Bull, are sold under agency rules governing beverages, while others, like 5-Hour Energy and Monster Energy, are marketed as dietary supplements. The categories have differing ingredient rules and reporting requirements.

In an interview Wednesday, Daniel Fabricant, the director of the agency’s division of dietary supplement programs, said the agency was looking into the death reports that cited 5-Hour Energy. He said that while medical information in such reports could rule out a link with the product, other reports could contain insufficient information to determine what role, if any, a supplement might have played.

Mr. Fabricant said that the 13 fatality reports that mentioned 5-Hour Energy had all been submitted to the F.D.A. by Living Essentials. Since late 2008, producers of dietary supplements are required to notify the F.D.A. when they become aware of a death or serious injury that may be related to their product.

This is dubious, unless many bottles were consumed in short succession. But at $3 a bottle, that's a little self-limiting.

Can someone explain the supposed synergism between caffeine and taurine?
 
^ it's a "supposed synergism" i assume they just potentiate each other creating a larger "energetic effect"... aka i really don't know

this article is just like the one about monster which the article mentions... both seem rather unfounded...
obviously its known that caffeine is a "stimulant drug" so if you have too much it = bad
and we know society is full of people that will overdo anything given the opportunity and this stuff is so widely available
 
A review published in 2008 found no documented reports of negative or positive health effects associated with the amount of taurine used in energy drinks, concluding that "The amounts of guarana, taurine, and ginseng found in popular energy drinks are far below the amounts expected to deliver either therapeutic benefits or adverse events".

From Clauson, KA; Shields, KM; McQueen, CE; Persad, N (2008). "Safety issues associated with commercially available energy drinks". Journal of the American Pharmacists Association : JAPhA 48 (3): e55–63; quiz e64–7.

can somebody summarize what this means:

The effects of taurine on Ca2+ uptake by the sarcoplasmic reticulum and Ca2+
sensitivity of chemically skinned rat heart.


Steele DS, Smith GL, Miller DJ.

Institute of Physiology, University of Glasgow.

1. Caffeine (10 mM) induced a transient contracture in saponin-treated cardiac
trabeculae as a result of Ca2+ release from the sarcoplasmic reticulum (SR).
Regular cycles of uptake and release were repeated to stabilize responses. The SR
accumulated Ca2+ during the period prior to the addition of caffeine and this was
reflected in the size of the caffeine contracture. Increasing the time for Ca2+
loading between successive caffeine exposures resulted in an increase in the
amplitude of the contracture. Similarly, the size of the contracture was a
function of the calcium ion concentration [( Ca2+]) in the preceding loading
period. 2. Taurine (microM-40-mM), when included in both loading and caffeine
solutions, markedly potentiated the caffeine-induced contracture. The effect
occurs even if taurine was included only in the loading solutions. The
potentiating effect was ascribed to a direct action of taurine on the SR, since
taurine did not significantly change the [Ca2+] in the loading solutions. 3. The
maximal effect of taurine was produced at approximately 5 mM; higher taurine
concentrations caused a lesser potentiation of the caffeine contracture. If the
solutions were balanced with respect to osmolarity the effect of taurine did not
decline at high concentrations. 4. If the [Ca2+] in the loading solutions was
increased to produce a caffeine-induced contracture that peaked close to maximal
Ca2(+)-activated force, taurine caused a fall in the size of contracture and a
more variable response. This result could be explained by an increase in the
spontaneous release of Ca2+ from the SR in the presence of taurine. 5. In
Triton-skinned trabeculae, taurine (1 mM-40 mM) increased the Ca2+ sensitivity of
the contractile proteins in a dose-dependent manner but had little effect on
maximum Ca2(+)-activated force. The increase in Ca2+ sensitivity was small: in a
typical experiment 30 mM-taurine reduced the [Ca2+] necessary for half-maximal
activation from 3.02 to 2.56 microM, with no significant change in the shape of
the relationship.
