What's in it
Each ingredient is in its most bioavailable form, at a clinically meaningful dose. No fillers, no token amounts, no marketing-led blends.
Zinc citrate
Zinc (as zinc citrate)
Required for thyroid hormone synthesis and for the action of thyroid hormone nuclear receptors. Zinc deficiency impairs both T4 production and T3 receptor binding.
156.5 mg (equivalent zinc 50 mg per tablet)
Always read the label and follow directions for use. Vitamins and minerals can only be of assistance if dietary intake is inadequate. If symptoms persist, consult a healthcare professional.
How to take it
Simple to take, with a few timing notes that make a real difference to absorption.
As directed. Typically taken with food. Do not take on an empty stomach, may cause nausea.
Do not exceed recommended dose, chronic high-dose zinc (above 40mg daily) can impair copper absorption. Zinc supplementation should be matched with dietary assessment and testing where possible. Dietary supplements should not replace a balanced diet.

Common questions about how OptiLabs works: testing, supplements, clinician review, returns and timing.
When is the best time to take zinc?
With food — zinc taken on an empty stomach commonly causes nausea. Avoid taking with iron supplements at the same time as they compete for the same intestinal transporters.
Are the supplements safe?
All carry an AUST L designation from the TGA. Every order is reviewed by a clinician before dispatch.
Do I need a referral?
No. All tests are available to order directly. Our lab partner is NATA and RCPA accredited, operating as a direct-access pathology service.
