Speed Supplement for Women Works, Says Study

Are you a woman runner and looking for an edge in your next race? Here’s what one study says about a speed supplement for women and the reason why it may be sex specific.


A recent news release from The Ohio State University states that women who took a specially prepared blend of minerals and nutrients for just one month saw their 3-mile run times drop by almost a minute. In addition, improvements in speed were also noted in stationary bike tests and step bench tests by women who tried the supplement.

The findings of the speed supplement study published in the Journal of the International Society of Sports Nutrition consisted of recreational female athletes ranging in age from 18 to 30 years old who had regularly engaged in aerobic exercise—that included running—for at least two to three hours a week for six months.

The study participants were divided into a test group that was provided with the supplement and a control group that received the placebo. Improvements in the test group performance were statistically significant and were not observed in the placebo group.

“The run-time drops in people at this stage of life were pretty large when they took the supplement. And in the placebo group, we saw little change,” said Robert DiSilvestro, the lead author of the study and a professor of human nutrition at Ohio State

The published results consisted of two separate experiments. In the initial experiment, with 14 women athletes taking the supplement and 14 taking a placebo, the supplement group performance improved by:

• a drop from 26.5 minutes on average to 25.6 minutes during a 3-mile run.
• an increase in distance covered in 25 minutes from 6 miles to an average of 6.5 miles.
• an increase in timed steps from 40 to 44 steps during a 90-second event.

In the second experiment—designed to see if the first was reproducible with a lower dose of the speed supplement—a new group of 36 women were put to the same 3-mile run test one month after taking the supplement or the placebo. What the data showed was that those who took the supplement had a 41-second average decrease in run times.

So, just what was put into the speed supplements?

According to the published paper, the speed supplement was concocted into two formulations:

Formulation #1: 36 mg iron as ferrous sulfate, 2 mg copper as copper gluconate, 15 mg zinc as zinc gluconate, 2 g carnitine as carnitine tartrate (Carnipure® donated by Lonza, Basel, Switzerland), and 400 mg phosphatidylserine (SerinAid® donated by Chemi Nutra, Austin, TX).

Formulation #2: 36 mg iron as iron bisglycinate (Ferrochel® donated by Albion), 2 mg copper as copper glycinate (Albion), 15 mg zinc as zinc glycinate (Albion), 2 g carnitine as Carnipure® (Lonza), and 400 mg phosphatidylserine as SerinAid® (Chemi Nutra).

The choice of nutrients used in the speed supplements are hypothesized to work especially in active young women due to micro-deficiencies that can lead to sub-par performance, which via the supplement then literally brings a woman’s body back up to speed.

“We know that young women, in particular, often have micro-deficiencies in nutrients and that those nutrients play a role in how cells work during exercise…they tend to eat less meat than men, and menstruation also plays an important role in mineral loss,” stated DiSilvestro in the news release.

“I decided to start with minerals that are commonly low – or thought to be low in many diets – and brought in some of the supporting cast. These two nutrients, which are needed for cell function, are made by our bodies but also come from food we eat.”

Plans are in the works for putting the supplement in the commercial supplement market and is expected to cost between $35 and $40 for a month’s supply.
