I’ve been dealing with stress and anxiety for years, and honestly, this Ashwagandha KSM-66® from Brainbox Life has been a game changer. Within two weeks, I felt noticeably calmer and more grounded, like I could handle life’s ups and downs without feeling so overwhelmed.


I also sleep better now, and my mood feels much more even throughout the day. It’s subtle, but you really notice the difference over time.


I love that it’s vegan, GMP certified, and made with root-only KSM-66®, which I learned is the purest form. It’s great knowing it’s backed by proper research too.

I started taking Brainbox Life’s Ashwagandha KSM-66® a few weeks ago, mainly to help with focus and energy at work. The results have been brilliant, I feel much calmer under pressure, yet more alert and productive throughout the day.

I was skeptical at first, but this Ashwagandha KSM-66® from Brainbox Life has genuinely made a difference. Within about 10 days, I started feeling calmer and less reactive to daily stress, things that used to overwhelm me now feel manageable.

I bought this for my daughter who was having problems with focus and memory. She is reporting benefit, early days but seems to be having some effect so far. Easy to take capsule form of a potent extract form of Lions Mane.

BrainBox.Life has brought together Ashwagandha Root Extract of 500 mg in a capsule. That's a really good dose, and I highly recommend people to reach for those sorts of doses, especially if you've got quite high pressure, high performance, high demanding lifestyles.

These nootroopics-infused chocolate packed a punch. After eating one bar or two, it was like coffee but without triggering my acidity.

I often hear the word "energise" in supplements ads that I don't expect it anymore. Lo and behold, after eating this, I was awake for 5-6 hours at work. Would recommend if you like chocolate, are trying to reduce coffee intake, and wanting to focus at work.

These nootropics-infused chocolates really surprised me. After one or two pieces, I felt alert and focused like having a good cup of coffee, but without the jittery stomach or acidity.

I’m usually skeptical when I see the word “energizing” on supplement ads, but this actually delivered. I stayed awake and clear-headed through my entire afternoon at work. If you love chocolate, want to cut down on coffee, or just need something to help you focus without the crash, this is definitely worth trying.
