The essentials

A closer look.

Douglas Labs Zinc Lozenges deliver elemental zinc in a dissolvable lozenge format, supporting immune function and upper respiratory wellness. The lozenge delivery allows zinc to make direct contact with throat tissues, which may support localized immune response more readily than standard swallowed tablets. This product is suited for adults seeking targeted immune and throat support, particularly during seasonal challenges.

Why It's Worth Considering: Douglas Labs is a practitioner-trusted brand with a long history of rigorous quality manufacturing; the lozenge form maximizes mucosal exposure compared to capsule delivery.

More category questions

How much zinc should I take daily?

For maintenance, 15-30mg of elemental zinc daily. For immune support during illness, up to 50mg for 1-2 weeks. The tolerable upper limit is 40mg/day for long-term use. Always balance with 2mg copper per 30mg zinc to prevent copper depletion.

What is the best form of zinc?

Zinc picolinate has the highest bioavailability in clinical studies. Zinc bisglycinate (chelated) is the most GI-friendly. Zinc carnosine is specifically indicated for gut healing and H. pylori. Zinc gluconate is primarily used in cold lozenges for topical throat contact. Avoid zinc oxide (poorly absorbed).

Can zinc help with acne?

Yes. Multiple studies show 30mg zinc gluconate or picolinate daily reduces inflammatory acne by 30-50% over 3 months. Zinc reduces sebum production, fights acne-causing bacteria, and modulates inflammation. It's comparable to low-dose antibiotics for mild-moderate acne.

Should I take zinc on an empty stomach?

No — zinc on an empty stomach commonly causes nausea. Take with food. However, avoid taking with high-phytate foods (whole grains, legumes) or calcium-rich foods as they reduce zinc absorption. A small meal with some protein is ideal.

Does zinc affect testosterone?

In zinc-deficient men, supplementation can significantly increase testosterone (one study showed a 73% increase over 6 months of repletion). In men with adequate zinc, the effect is minimal. Zinc supports the enzyme 5-alpha reductase and is concentrated in the prostate gland. Athletes who sweat heavily often have marginal zinc status.
