Rhodiola is a herbal plant found to dramatically increase the level of feel-good neurotransmitters (brain activity) including serotonin and other feel-good neurotransmitters. It's helpful, active ingredient is called a rosavin - a measure of it's concentration.
...Hmm, sounds interesting but...
COMT (catechol-O-methyltransferase) is an enzyme that breaks down these neurotransmitters.1 However, Rhodiola slows the effect of this.
...Sounds good. But how long does that take? -Tell me...
The effect can be felt quickly. In fact, often, merely days of taking a supplement with it, people taking Rhodiola find they have an increase in energy and motivation, lower levels of anxiety as well as better confidence and optimism.
...Oh yes! But before I get too excited, has there been any proof and by...
Before becoming known in the United States, Rhodiola was extensively studied by Russian scientists and was used for decades in the former Soviet Union as an energy-enhancer.
Since then, numerous researchers have conducted double-blind, placebo-controlled clinical trials and found that Rhodiola can increase general wellbeing2, reduce mental fatigue2,3, and improve learning and memory4.
...Ok, I'm sold. I getting some - tell me...
Here at Nature's Remedies, we searched pretty hard for a good all-round product and found... A neat-o supplement called, AMORYN. Each of their capsules has 90mg of Rhodiola extract. They standardize it to contain a potent amount of at least 4% rosavins (most other Rhodiola supplements contain only 1-2% rosavins). Yet this daily dose provided by AMORYN is the amount of Rhodiola extract shown to be both effective and safe in clinical trials.
