Zinc Bisglycinate 25mg with Copper
A chelated zinc bisglycinate supplement at a higher-absorption form and dose than a standard daily pick, with copper bisglycinate individually disclosed alongside it specifically to offset the copper-depletion risk that sustained higher-dose zinc use creates.

CURATEDFIT SUMMARY
Passes because both active minerals, zinc bisglycinate (25mg elemental zinc) and copper bisglycinate (1mg elemental copper), are individually disclosed with separate exact amounts, not combined under one ambiguous total. Bisglycinate is a genuinely better-evidenced absorption form than the picolinate form used in this catalogue's other zinc pick (Osavi), and the copper inclusion isn't padding, it directly addresses a real, well-documented interaction: sustained zinc supplementation depletes copper over time. Worth knowing this is a meaningfully higher zinc dose than a standard daily-maintenance amount, see the Transparency Note for how this compares against the Osavi option and which one actually fits which situation.
WHAT IT IS
A UK-manufactured tablet providing 25mg of elemental zinc as zinc bisglycinate and 1mg of elemental copper as copper bisglycinate, made to GMP standards without magnesium stearate, using a rice-derived flow agent blend instead.
WHO IT IS FOR
Someone specifically wanting the more absorbable bisglycinate form of zinc, or supplementing at a higher dose than standard daily maintenance, where the built-in copper safeguard matters more. Not the first choice for someone who just wants a simple, lower-dose daily zinc, see the Osavi Zinc Picolinate review for that use case instead.
INGREDIENT BREAKDOWN
Ingredient Amount per Serving (1 tablet) Form
Zinc Bisglycinate (providing 25mg elemental Zinc)
25mg elemental zinc
Chelated organic mineral form. Both actives are individually disclosed with separate exact amounts, this is not a combined-total blend the way both of Life Extension's zinc products are. The rice extract blend functions as a natural flow agent replacing magnesium stearate, disclosed as a named group rather than hidden.
Copper Bisglycinate (providing 1mg elemental Copper)
1mg elemental copper
Chelated organic mineral form

TRANSPARENCY NOTE
Worth comparing this directly against the other zinc option in this catalogue, Osavi Zinc Picolinate, since the two aren't redundant, they fit different situations. Osavi delivers 10mg of elemental zinc as picolinate, a form with decent but older, more mixed evidence, at a dose matching standard daily maintenance needs (100% NRV), with no added copper because none is needed at that dose. This product delivers 25mg of elemental zinc as bisglycinate, a form with stronger, more consistent modern evidence for absorption and gastric tolerance, but at two and a half times the standard daily dose, which is exactly why copper is included here. Sustained zinc intake above maintenance levels measurably depletes the body's copper stores over time, and the 1mg copper bisglycinate is included specifically to offset that, not as an added benefit claim.
In short: better absorption and a real safeguard for the dose, but also a meaningfully higher dose than most people need for routine daily maintenance. Someone wanting a straightforward, standard-dose daily zinc is better served by the Osavi pick. Someone with a specific reason to supplement at a higher zinc level, or who prioritizes the stronger-evidenced bisglycinate form, is better served by this one, with the copper inclusion meaning that choice doesn't come with the same long-term risk the Peak Supps 50mg zinc bisglycinate product (also checked during sourcing, and explicitly not intended for long-term use) would carry.
FREQUENTLY ASKED QUESTIONS
Why is this dosed so much higher than the Osavi zinc pick?
This isn't meant to replace a standard daily zinc, it's positioned for someone specifically wanting the bisglycinate form's better absorption, or supplementing above maintenance levels for a specific reason. The copper inclusion is what makes that higher dose safer for sustained use.
Do I need the copper if I'm only taking this occasionally?
The copper depletion risk is specifically tied to sustained, ongoing zinc supplementation. For short-term or occasional use, it matters less, but it's included regardless as a built-in safeguard.
Which zinc product should I actually pick, this one or Osavi?
If in doubt, start with the Osavi Zinc Picolinate for standard daily maintenance. Reach for this one specifically if you want the more absorbable form or a higher dose for a particular reason.
