Meet Diana
Diana Famintsyna is the founder and owner-operator of Top Nutrition & Fitness in Montreal, Quebec. She opened the first physical TNF location in July 2016 after a decade in the supplement industry — first as a competitive athlete trying to navigate Canadian retail (and being frustrated by stale flavors, missing US brands and pushy upsells), then as a buyer for several Montreal-area health stores. TNF was her answer to the question: "What would a supplement shop look like if every product on the shelf had been taste-tested by the owner first?"
What makes TNF different
- Owner taste-tests everything. Diana personally tries every flavor before it goes on the shelf. If a bar tastes like cardboard, it does not get carried — no matter how good the margin is.
- Authorized retailer for 100+ brands. No grey-market imports. No expired stock cleared from a closing competitor. Real warranties, real freshness, real distribution.
- Canada's widest singles catalog. Most retailers force you into 12-bar boxes. TNF stocks singles so you can try before you commit.
- Only Canadian retailer for several US brands. Bowmar Nutrition, ChocZero USA flavours, Simply Scrumptous, Built USA, Barebells USA.
- 5% cash back rewards on every order. Stacks with Onward 90-day satisfaction protection if you opt in.
E-E-A-T credentials
- Experience: 13+ years in the Canadian supplement industry as a buyer, trainer and operator.
