Our Verdict: Thorne Zinc Picolinate or Solgar Zinc Picolinate?
Thorne wins with superior ingredient quality (91 vs 82) and higher effectiveness, but at £21.38 costs more than double Solgar's £9.99. Choose Solgar if budget matters more than premium testing — the 6-point score gap may not justify doubling your spend.
