WHY RAIN IS BUILT DIFFERENT

Five reasons RAIN works when other supplements don't.

REASON 01

20:1 concentrated extracts, not raw powder

Every mushroom and adaptogen in RAIN is a 20:1 concentrated extract. This is double the concentration of most others on the market. More strength in every capsule, less filler.

20:1

20:1 meaning our 100mg is equivalent to 2000mg

REASON 02

Triple-extracted for maximum absorption

Potency isn't just milligrams — it's how much your body can actually use. Our triple-extraction method (water + ethanol) pulls far more active compounds from each plant than standard water-only extraction, for a more bioavailable formula that works faster.

REASON 03

Clinically meaningful doses. No fairy dusting.

The industry's dirty secret: listing an impressive ingredient at a dose too small to do anything. We dose every active at the level the research says actually works — never just enough to look good on the label.

REASON 04

Best-in-class, standardised ingredients

We pick the exact form of each ingredient with the strongest science behind it. The details are where potency is won or lost.

REASON 05

Capsules that deliver the full dose

Gummies lose potency to sugar and coatings. Powders get watered down with binders and flavourings. Our capsules deliver the complete formula cleanly, with nothing lost on the way in.
