Nutrition Geeks, Vitamin D 4000 iu - 1 Year Supply, 365 Easy-Swallow Tablets Vegetarian D3 iu, High Strength Supplet UK Made VIT & Vitamins Awarded by The Independent

Overview

We keep Nutrition Geeks Vitamin D 4000 iu - 1 Year on our vitamin d shelf alongside 50 others, and rank it on rating, review volume and live price rather than on the brand. The manufacturer puts it this way: 12 Month Supply of Vitamin D3 tablets Made by British PhD Geeks: Each pouch contains 365 vit d3 4000 iu tablets that are scientifically proven to support your immune system making it ha. Our vitamin d high strength tablets have been uniquely formulated to be just 6mm in diameter - so small you won't even notice when you swallow them! Although smaller. That is the maker talking, not us, so read it as a claim rather than a finding. On Amazon it sits at 4.7 out of 5 across 3,300 ratings. How that compares with the rest of the shelf is below.

How it compares on the vitamin d shelf

The typical vitamin d product on our shelf scores 4.7 out of 5, measured across 51 rated products. This one comes in at 4.7. That's mid-table. Star ratings won't separate this from its neighbours, so the decision comes down to pack size, price per unit and whether the specifics below suit you.

Behind that score sit 3,300 ratings, against a shelf median of 1,800. Enough reviews to trust the direction, not enough to close the question.

The shelf runs from £3.50 to £29.99 and the midpoint is about £8.99. On price, this one is in the middle third. Which is where most sensible buys end up: not the cheapest on the shelf, and not the one you pay a name for.
