Watch: Sedation in a tasty solution! ⭐⭐⭐⭐ Review of Liposomal Ashwagandha & L-Theanine by Youth & Earth

Recently I’ve been taking two teaspoons of this velvety sedating solution before bed with my wife. And, this is one supplement that you “feel” — it, no doubt, has a relaxing effect. I get to sleep consistently within 10 minutes after lights out in the Roseland bed chamber. My wife falls asleep even faster, often I make it less than a minute into this bedtime story that I’m coming up with before she nods off.

When I do an intermittent period of no booze, I like to have something to take the edge off at dinner. Often I’ll sip a Phenibut infoceutical, but a few teaspoons mixed in a glass of water also worked.

Order: Liposomal Ashwagandha & L-Theanine by Youth & Earth

There are no human clinical studies evaluating the combination of the two so I’ll summarize some of the recent science done individually on the ingredients.

Some recent science has explored the potential of Ashwagandha for combating COVID infection, from a 2022 review

The herbal medicine Withania somnifera has an excellent antiviral activity that could be implicated in the management and treatment of flu and flu-like diseases connected with SARS-CoV-2… Withania somnifera has proved its potential for maintaining immune homeostasis of the body, inflammation regulation, pro-inflammatory cytokines suppression, protection of multiple organs, anti-viral, anti-stress, and anti-hypertensive properties. Withanoside V has the potential to inhibit the main proteases (Mpro) of SARS-CoV-2.

A Belgian-Saudi-Pakistani review suggests Ashwagandha as a potential drug candidate for integrative cancer chemoprevention and cure.

A case report out of the UK relates…

A 39-year-old female presented with a one-week history of jaundice and nausea after taking an over-the-counter herbal supplement containing ashwagandha root extract.

I’d sure like to know what else the herbal supplement contained and if the Ashwagandha she took was perhaps the problematic KSM-66 variant. This case report is a sobering reminder that herbal supplements are not universally safe, in fact, many contain troubling amounts of impurities. This is why you get your Ashwagandha from a credible source and pass on the cheap stuff in the white plastic bottles.

Moving on to the recent L-Theanine science, a double-blind, randomized, placebo-controlled 2021 Japanese study found that…

The single dose of l-theanine reduced the reaction time to attention tasks… and it increased the number of correct answers and decreased the number of omission errors in working memory tasks… our study indicated that l-theanine may contribute to improving attention, thus enhancing working memory and executive functions.

It does note that it decreased reaction time to attention tasks — so maybe don’t drop L-Theanine before a competitive gaming session.

Although a 2022 study of 27 healthy young adults notes that…

L-theanine can increase attentional processing of auditory information in a dose-dependent manner.

So maybe drop some before editing podcasts or producing music.

A proof-of-concept neuroimaging randomized controlled trial evaluated a combination of L-Theanine and caffeine for treating ADHD in boys.

L-Theanine-caffeine combination may be a potential therapeutic option for ADHD-associated impairments in sustained attention, inhibitory control and overall cognitive performance.

I’m a big fan of Youth & Earth’s liposomal solutions because they take taste engineering seriously!

And the coffee-vanilla flavor of this one is no exception, you’ll enjoy it!
