Serenity Supplements — Coming Soon
Ashwagandha KSM-66
Reserve your first batch
Our first supplement is almost here. A clinically studied, full-spectrum ashwagandha for people who are tired of feeling wired, worn out, and unlike themselves.
Not just any ashwagandha.
The most researched form.
Most ashwagandha supplements use generic powder. Ours uses KSM-66 — the gold-standard, full-spectrum root extract standardised to 5% withanolides, backed by over 24 clinical trials.
- Supports a calmer nervous system without sedation — so you can feel settled, not switched off
- Clinically studied for stress, anxiety, and cognitive function — not just marketed that way
- Supports deeper, more consistent sleep — one of the hardest things to reclaim when you're overwhelmed
- Root-only extract. No fillers. No unnecessary ingredients. UK manufactured and fully compliant.

Reserve My PlaceYou're exhausted by feeling like this
Your mind won't stop
You lie awake replaying the day. Your nervous system runs at full speed even when nothing is actually wrong. You need something that actually helps you switch off.
You're running on empty
You wake up tired. You push through the day. By evening you're done — but you still can't sleep. That cycle needs to break, and you know willpower alone won't do it.
You want evidence, not hype
You've been burned by wellness products that promise everything. You want a supplement backed by real clinical research — not influencer marketing and vague claims.
"I spent 20 years trying to find what genuinely helped with anxiety, CPTSD, and the exhaustion that comes with it. Ashwagandha KSM-66 was one of the pieces that actually made a difference. I built this so you don't have to spend two decades working that out."
Philip — Founder, Serenity SupplementsBacked by peer-reviewed clinical research
