Igennus Clean Chelated Zinc Pico...
Pros
- ✓Highly tolerated — multiple reviewers explicitly note no nausea or stomach upset, even when taken on an empty stomach
- ✓Copper bisglycinate included at a balanced ratio, preventing zinc-induced copper depletion for safe long-term use
- ✓Dual chelated forms (picolinate + bisglycinate) offer superior absorption over cheaper gluconate or oxide forms
- ✓Clean, verifiable formula — no magnesium stearate, titanium dioxide, artificial colours, or fillers; UK GMP-manufactured
Cons
- ✗Not effective for all conditions — one reviewer saw no benefit for gastritis, and zinc's evidence for gut inflammation is limited
- ✗Effects take time to assess; short-term users (under 2–4 weeks) cannot judge efficacy reliably
- ✗Third-party testing not independently confirmed despite 'lab verified' marketing claim
- ✗Tablet form may not suit those preferring capsules or liquids

What does the data say about Zinc Picolinate 22mg vs Igennus Clean Chelated...?
Both products use zinc picolinate as their base form, which is among the better-absorbed options compared to cheaper oxide or gluconate. The key difference is that Igennus adds zinc bisglycinate alongside the picolinate, plus includes copper bisglycinate in the formula itself — meaning you get a dual-chelated complex in one tablet. Thorne's offering is a single-form zinc without copper, so you'd need to supplement copper separately if using it long-term. Thorne scores higher overall at 85/100 versus Igennus's 81/100, but Igennus edges ahead on value at 83/100 compared to Thorne's 74/100 — and at £14.95 for 180 tablets, the price difference is substantial against Thorne's £21.38.
If you want the simplest, highest-quality single-ingredient zinc and don't mind managing copper separately, Thorne is the cleaner choice — particularly if you're already taking a multi that includes copper. Its ingredient quality score of 91/100 reflects Thorne's well-regarded manufacturing standards.
For most people, though, Igennus makes more practical sense. The built-in copper removes the need for an extra supplement, stomach tolerance appears better across reviewers, and the six-month supply format suits anyone looking to commit to consistent long-term use without frequent reorders.
Thorne Zinc Picolinate is a well-regarded supplement using zinc picolinate, one of the most bioavailable forms of zinc, bound to picolinic acid for superior absorption even in low-stomach-acid conditions.
