Zinc (as zinc gluconate)
Jafari et al., 2022 · Journal of Trace Elements in Medicine and Biology
Meta-analysis of RCTs; 35 randomized controlled trials included; participants with various health conditions
A meta-analysis of randomized controlled trials found that participants who received zinc supplementation showed statistically significant reductions in inflammatory markers including C-reactive protein, interleukin-6, and tumor necrosis factor-alpha compared to those who received placebo; effects varied across populations and zinc forms studied.
Participants with zinc insufficiency who received zinc gluconate supplementation showed statistically significant improvements in serum zinc concentrations and natural killer cell cytotoxicity compared to those who received placebo; the study population had baseline zinc insufficiency and results may not generalize to zinc-sufficient individuals.
Dawson-Hughes et al., 1990 · New England Journal of Medicine
Randomized, double-blind, placebo-controlled trial; n=301; 2 years; postmenopausal women
Postmenopausal women who received calcium supplementation showed statistically significant reductions in bone loss at the spine and femoral neck compared to those who received placebo; effects were most pronounced in women more than six years past menopause, and results are specific to this demographic.
Systematic review and meta-analysis; 43 randomized controlled trials included; various adult populations
A meta-analysis of randomized controlled trials found that participants who received calcium supplementation showed statistically significant improvements in bone mineral density at multiple skeletal sites compared to those who did not; effect sizes varied by supplementation form, dose, and baseline calcium status.

How it works
Every ingredient, chosen with intention.
Here's what's in this bottle - and why each ingredient earned its place in the formula.
Zinc
as zinc gluconate
A trace mineral involved in the function of over 300 enzymes in the body, participating in cellular metabolism, protein synthesis, and immune cell activity.
Why we chose it
Formulated as zinc gluconate, zinc bonded to gluconic acid, a naturally occurring acid found in fruit, rather than zinc oxide, the cheapest and least bioavailable form commonly used in supplements. Gluconate dissolves readily in water and is better studied for absorption than oxide forms.
A plant-based amino acid the body uses to build collagen and support the structural health of skin, tissue, and bone.
Questions, answered
What customers often ask.
The dose is 455% of daily value, is that safe?
The Daily Value for zinc is set at 11mg as a population-wide minimum. Many clinical studies use doses in the 25–50mg range. The upper tolerable intake level established by health authorities is 40mg/day, and this product contains 50mg, so if you take other zinc-containing supplements or multivitamins, check total zinc intake and consult your healthcare provider.
Should I take this with food or without?
The formula is described as gentle on the stomach and can be taken with or without food. If you find zinc causes any nausea on an empty stomach, taking it with a meal resolves this for most people. Zinc gluconate is a gentler form than zinc sulfate, which is more commonly associated with stomach upset.
What makes zinc gluconate better than zinc oxide?
Zinc oxide, the cheapest form in most budget supplements, is poorly soluble in water and has lower bioavailability. Zinc gluconate is zinc bonded to gluconic acid, a naturally occurring acid found in fruit. It dissolves readily and is better studied for absorption than oxide forms.
Does long-term zinc supplementation affect copper levels?
Zinc and copper compete for absorption in the gut, and sustained high-dose zinc can gradually reduce copper status. If you plan to take zinc daily long-term, consult your healthcare provider, they may recommend periodic monitoring or a copper supplement to balance intake.
Can I take this during cold and flu season?
Zinc is one of the most-studied minerals in relation to immune function. Research shows that participants with zinc insufficiency who received zinc gluconate showed improvements in immune cell activity. For ongoing immune support, daily use throughout the year tends to be more effective than short-term use.
Is this safe during pregnancy?
Zinc is an essential nutrient during pregnancy, but the required and upper-limit amounts differ from the standard adult dose. Please consult your healthcare provider or OB before taking this supplement while pregnant or breastfeeding.
