In this fast paced world‚ everyone suffers from stress related to work‚ school‚ relationships etc. Theanine Serene™ 30 Tablets from Source Naturals may help ease the tension. It contains L-theanine‚ an amino acid that could possibly reduce mental and physical stress‚ and improve cognitive performance.

Studies show that it could boost the amount of the feel-good hormone your body makes‚ hence relieving anxiety. L-Theanine is an important constituent of green tea and is now used in various foods including chocolates‚ soft drinks‚ and herbal teas.

Theanine Serene™ 30 Tablets from Source Naturals also contains taurine‚ which is essential for good cardiovascular function‚ development‚ and function of skeletal muscle‚ the retina‚ and the central nervous system. The supplement contains Gamma-Aminobutyric Acid (GABA)‚ a neurotransmitter. Researchers think that GABA may boost your mood and have a calming‚ relaxing effect on the nervous system. It may also promote lean muscle growth‚ burn fat‚ stabilize blood pressure‚ and help relieve pain.

This supplement also contains magnesium‚ which may be essential for muscle and nerve relaxation and overall wellness.

The holy basil leaf is believed to soothe away the tension in your body. These stress busters are suitable for vegetarians. The Theanine Serene™ 30 Tablets from Source Naturals contains no yeast‚ dairy‚ egg‚ gluten‚ soy‚ wheat‚ sugar‚ starch‚ salt‚ preservatives‚ artificial color‚ flavor‚ or fragrance.

    • Works great for me

    • Love it

      from SC on 10/06/2021

    • I like it!

      from Southern California on 7/16/2021
      I like Serene Science Theanine Serene because it has a potent "cocktail" of ingredients that are effective on their own, but seem more so together. The l-theanine is proven to have a calming effect, but when I take it with caffeine, it often improves my focus. The holy basil extract is a potent anti-inflammatory and adaptogen. And the magnesium is tops for relaxation and keeping things moving through the digestive tract.

      Great for light sleepers

      Helps me fall asleep quicker, and helps me to sleep through the night.

      Works!

      from Michigan on 3/02/2020
      I have adrenal issues. I take this to help me relax and sleep at night. I was taking this with Brain Calm, and when I ran out of Brain Calm, I didn't notice a difference; but if I don't take Theanine Serene, I won't sleep! So this is obviously the one that helped. I have also taken them in split doses (one in the morning and one at night), rather than both at night. It is helpful in the daytime as well, and doesn't make me tired during the day.

      Pros

      I can sleep when I take it; and when I do get up during the night, I go back to sleep rather than lie there.

      Cons

      I wish it didn't have sorbitol in it.

      Reliable relaxation

      from Maine on 12/06/2019
      I've been using Theanine Serene for close to 4 years. I use it as needed at bedtime to alleviate physical and mental tension. I often toss and turn, and on the nights that I use this supplement, I fall back to sleep much more quickly - and I don't have a jolt of panic when I wake up. I have also taken it during the day, 15 mins before doing something that would normally make me mildly anxious (e.g. phone conference with my boss), and I felt settled and receptive. Every batch that I've ordered has worked consistently.

      Pros

      Effective quickly Have not gained a tolerance

      Cons

      Pills are a bit large.
