Question 1

What is the Weekly Evidence Bulletin?

Accepted Answer

The Weekly Evidence Bulletin is Vitagri's Monday-morning briefing that interprets the past seven days of additions to the Pulse Brain Growing Health Evidence Index — currently 18,000+ peer-reviewed studies and industry reports on soil health, farming systems, nutrient density and human health. Each issue is written in five persona-specific cuts (Farmer, Food Buyer, Investor, Academia, Nutritionist) so readers can jump straight to the implications for their role.

Question 2

When is the bulletin published?

Accepted Answer

Every Monday. A new issue is published at 09:00 UK time after editorial review. The previous week's catalogue additions are synthesised into the five persona cuts, tier-graded against Pulse Brain's evidence hierarchy, and UK-contextualised before release.

Question 3

How do I subscribe to the Weekly Evidence Bulletin?

Accepted Answer

Subscribe on Substack at https://vitagri.substack.com to receive each Monday's issue in your inbox, or read online at https://vitagri.org/evidence/bulletin/. You can also browse previous issues by persona at /evidence/bulletin/<persona>/ — for example /evidence/bulletin/farmer/ for every Farmer cut ever published.

Question 4

Which personas does the bulletin cover?

Accepted Answer

Five: Farmer (evidence for practice), Food Buyer (supply-chain signals), Investor (market and thesis updates), Academia (fresh literature worth citing) and Nutritionist (dietary and clinical evidence). Every weekly issue contains all five cuts on one page, or each can be browsed chronologically at its own persona feed URL.

Question 5

How is the evidence quality-graded?

Accepted Answer

Every Pulse Brain record is assigned a tier: T1 (meta-analyses and systematic reviews), T2 (randomised controlled trials and large cohort studies), T3 (observational studies and field trials) and T4 (narrative reviews, commentaries, guidelines). The bulletin surfaces tier-graded studies so readers can weight claims appropriately.

Question 6

Is the bulletin free?

Accepted Answer

Yes. The bulletin, the underlying Pulse Brain catalogue, and the Pulse AI research assistant are all free to browse. The catalogue's full API is also free for academic use.
