Effects and Benefits

Zinc citrate provides you with a trace element that is involved in over 300 metabolic processes. Your immune system, your hormones, and your recovery only function optimally with a sufficient zinc supply. Physical exertion increases your requirement – this supplement quickly replenishes your stores.

How Zinc Citrate Works in the Body

You use this mineral for cell division, DNA synthesis, and immune defense¹,⁴. The trace element contributes to a normal function of the immune system¹,³ and supports the maintenance of normal skin, hair, and nails. Zinc citrate, as an organic compound, is absorbed significantly better in the small intestine than other zinc forms¹³,¹⁴ and enables rapid availability in the bloodstream.

High Bioavailability for Maximum Absorption

This zinc form has a demonstrably higher absorption rate than zinc oxide or zinc sulfate¹³,¹⁴. You absorb up to 61 % of the active ingredient it contains.

That means: more of it arrives where you need it. With zinc citrate tablets, bioavailability makes the difference between intake and actual effect.

Dosage and Use

Half a zinc citrate tablet daily optimally covers your zinc requirement. Each tablet provides 50 mg; the recommended daily dose of half a tablet corresponds to around 25 mg of zinc citrate with approximately 7.88 mg of elemental zinc².

Take the half tablet with water and a meal. This improves absorption and prevents stomach irritation.

The contents of 120 tablets last up to 8 months at this dosage.

How Much Zinc per Day Makes Sense?

Adults need between 7 and 16 mg of this mineral daily, depending on gender and physical activity². Athletes have a higher requirement due to sweat and increased metabolism⁷,¹¹.

With zinc citrate 50 mg tablets, the recommended intake amount is within the safe range and delivers an effective dose. The stated daily intake amount should not be exceeded.

Safe Use and Tolerability

At the recommended dosage, this zinc form is well tolerated⁸. Take the supplement with a meal – not on an empty stomach.

Avoid taking it at the same time as coffee or calcium-rich foods, as these can impair absorption. This dietary supplement is not a substitute for a balanced diet and healthy lifestyle.

Frequently asked questions about Zinc Citrate

What is zinc citrate good for?
Zinc citrate supports the immune system, metabolism and regeneration¹,³,⁴. Physical stress increases your requirement - the mineral compensates for losses. The trace element contributes to the normal function of the immune system¹,³, has an antioxidant effect⁴ and supports the maintenance of normal skin, hair and nails.

How much zinc citrate per day makes sense?
Half a tablet of zinc citrate 50 mg tablets provides around 7.88 mg of pure mineral per day. This optimally covers the needs of adults². Athletes have an increased need for this trace element due to sweat and intensive training⁷,¹¹. Studies show that up to 90 percent of endurance athletes may not consume enough of it. The recommended daily dose should not be permanently exceeded.

Is zinc citrate safe?
At the recommended dosage, this form of zinc is well tolerated⁸. The tolerable upper limit is 40 mg of the mineral per day for adults. Take the preparation with a meal to optimize absorption and avoid stomach irritation. Prolonged intake of very high doses over 50 mg daily may impair copper absorption.

What is the difference between zinc and zinc citrate?
Zinc is the chemical element, zinc citrate is an organic compound of the element and citrate. You can absorb this form much better than inorganic forms such as zinc oxide¹³,¹⁴. The citrate compound ensures higher bioavailability and faster availability in the bloodstream. The pure element cannot be directly utilized.

Is zinc better than zinc citrate?
This question is based on a misunderstanding. The pure element needs a compound such as citrate, gluconate or oxide to be utilized by the body. The citrate compound has been shown to have the best absorption rate¹³,¹⁴ and is therefore the most effective choice for your supplementation. Studies show a significantly higher absorption rate compared to inorganic forms.

Can I combine zinc citrate with other supplements?
Yes, this form of zinc can be combined very well with magnesium and vitamin D. These nutrients support each other in immune function and metabolism. Take the mineral at intervals (1 to 2 hours apart) with high-dose iron or calcium supplements to ensure optimal absorption. If you have any questions about combining with other supplements, our customer service team will be happy to help.

Does zinc citrate protect cells from oxidative stress?
Yes, the trace element acts as an antioxidant⁴ and activates the body's own protective mechanisms against free radicals. Intensive training increases oxidative stress in your muscles - a sufficient supply promotes cellular regeneration and accelerates recovery.
