Performance Nutrition,
Built By People Doing The Work

Calsanova exists because the tools practicing dietitians rely on every day are fragmented, slow, and built for someone else's workflow. We're fixing that.

Built by someone with first-hand experience

Nelson Marques, MS, RD, LD

Calsanova was created by Nelson Marques, MS, RD, LD — a Registered Dietitian and Performance/Tactical Dietitian for the United States Air Force, where he fuels AFSPECWAR (Air Force Special Warfare) operators at Patrick AFB.

With a Masters of Science, published research on ergogenic aids in collegiate athletes, and experience spanning elite military, professional, and collegiate sports nutrition, Nelson built Calsanova to solve the problems he faced daily: fragmented tools, manual SOAP notes, and meal plans that took hours instead of minutes.

Why I built this

Every day I sat down with an athlete or operator and opened five different tabs — one for their food log, one for body comp history, one for the meal plan template, one for the SOAP note, and one more to check their supplement stack against the current research. None of them talked to each other. Copy, paste, re-enter, double-check. Repeat for the next client.

The tools built for dietitians were designed by people who had never written a SOAP note at 0600 before a weigh-in. The tools built for athletes were full of ads, gated behind paywalls for basic features, and gave nutrition advice that ranged from questionable to dangerous. There was nothing in between — nothing built by someone who understood both sides of the table.

Calsanova is the tool I wish I had on day one. It's built around the actual workflow of a performance dietitian and the actual needs of the athletes and operators who sit across from them. No ads, no filler, no generic advice — just the platform I needed, now available to everyone.

Why Calsanova exists

The tools a practicing dietitian needs — food databases, meal planning, SOAP notes, client tracking, macro math — live in five different apps that don't talk to each other. The tools an athlete needs to log food quickly, see trends, and work with a real professional are either bloated with ads or locked behind a wall.

Calsanova brings the whole workflow into one place: a clean free tier for members, a professional suite for RDs and S&C coaches, and an AI layer that removes the busywork without replacing clinical judgment.
