Adapting to stress without prescriptions

It's a tight work deadline that does it to Spencer Brooks.

"That often means working long hours. That's usually when I get stressed out."

Brooks' solution: something called an "adaptogen."

"It just turns my brain on. I feel so sharp."

An "adaptogen" is defined as "a non-toxic substance, especially a plant extract held to increase the body's ability to resist the damaging effects of stress."

"When we're very stressed out the body releases a hormone called cortisol, and adaptogens work to normalize the levels of cortisol in our body," said Dr. Jennifer Wider, author and radio host.

Think ginseng, rhodiola, or arctic root, and ashwagandha, they are three of the most well-known adaptogens, all of which are popular right now according to Dr. Wider.

"They're popping up in all sorts of supplements, in drinks and in our food."

There's research to back the claims of effectiveness in everything from increasing mental performance to aiding in resistance to stress.

"Studies show that adaptogens can help people fight fatigue. They may help people that have trouble sleeping. They may boost our immune response," said Dr. Wider.

The Food and Drug Administration has "no warnings" concerning "adaptogens" as a supplement-- you can even add it to your coffee.

"It's a pretty powerful upgrade. It's about giving you more energy, increases your mental alertness," said Dave Asprey, Bulletproof Coffee Founder.

Dr. Wider said there can be complications if you take too much. Adaptogens can also potentially interfere with certain medications. But Brooks said he has had only positive results.

"It hands down changed my life."

It is a good idea to have a consultation with your doctor before giving adaptogens a try.
