Stop by a “musclehead” gym and you’ll discover something quickly. Bodybuilders take a lot of supplements. These guys (and ladies) are usually on the cutting edge of nutritional supplements.
And every once in a while, they hit on a one that delivers much more than they expect.
Take phosphatidylserine (PS), for instance. Bodybuilders use PS to boost exercise capacity, limit muscle damage and improve recovery. And there’s some evidence it does all these things.
But PS may also be the next big thing in anti-aging supplements. Here’s why…
Being trim and fit is one of best ways to fight the effects of age. And that means getting regular exercise.
Imagine if you could exercise more with less strain. That would be great. And it appears to be exactly what PS can help you do.
Scientists at the University of Wales put two groups of active men through a tough workout. The volunteers cycled for 10 minutes three times – at 45%, 55% and 65% of maximum effort. Then they cycled at 85% of maximum till they couldn’t go any longer.
One group then started taking PS, while the second group received a placebo. After several days, they went through the same series of cycling tests. The placebo group didn’t do any better cycling at 85% of maximum effort. But the PS group cycled 26% longer before running out of steam.1
The researchers got similar results when they tested PS on runners.2 So PS appears to boost your capacity for exercise.
Your body makes PS naturally. You’ll find the highest concentrations in your brain. And that got doctors thinking. Can a PS supplement have an effect on thinking and memory?
In a 2011 trial, people improved their scores on thinking tests after taking a PS supplement for two weeks. People given a placebo didn’t.3
PS appears to support memory, too.
A Japanese study looked at mature adults with cognition and memory problems. Those with the lowest memory scores before taking PS made significant gains over 6 months. Low scoring volunteers taking a placebo didn’t.4
A brand new study from Israel shows PS may help promote a good memory pretty quickly. In this trial, volunteers showed big gains in just 12 weeks.5
PS is available as a nutritional supplement. It’s usually extracted from soy lecithin. But you’ll find significant amounts in several foods.
Atlantic mackerel and herring, tuna, chicken liver and white beans are all rich in PS. Chicken breast, beef and pork also contain a fair amount.
The exercise studies used fairly high doses of PS – 750 mg. But the thinking and memory studies mostly worked with far less. 300 mg was a typical dose. That’s about 60% of the PS you’d get from a single serving of Atlantic mackerel.
Yours in continued good health,
