Maximum bioavailability through zinc bisglycinate

You may be asking yourself: "Zinc is zinc, right?" Not quite. The decisive difference lies in the chemical compound.

Cheap variants like oxides or sulfates often fall short. A large portion of them never reaches your blood but is excreted by the body unused.

Here comes the game changer: in bisglycinate, the mineral is firmly bound to two molecules of the amino acid glycine (a so-called chelate complex). Your body recognizes this structure as an amino acid and channels it through the "VIP entrance" across the intestinal wall, so to speak; zinc absorption is significantly more efficient with this form.

What this means for you: you get more active ingredient into your cells without unnecessarily burdening your stomach. So if you value efficiency, this organic compound is your first choice.

Highly dosed: perfect for athletes and increased needs

Let's be honest: for someone who lies on the couch all day, 10 mg is perfectly fine. But you are here at Gigas, so we assume you go all out.

While the normal daily requirement is often lower, athletes and bodybuilders have a significantly higher turnover. You lose valuable electrolytes and trace elements through sweat with every workout. A standard product is often simply not enough to refill the tank.

This is exactly where the 25 mg per serving comes in. This supplement was specifically designed for people with increased needs. It is not a "lifestyle candy" but a potent tool to keep your levels stable even during hard training phases.

More efficient support for testosterone & the immune system

What matters is not only what you take, but how much active ingredient actually arrives. Because the bisglycinate is absorbed so efficiently, it can optimally fulfill its tasks in the body.

Thanks to its high bioavailability, zinc contributes to:

  • Ensuring a normal function of the immune system (the body's defenses), essential when you push to your limit in training ("open window effect").
  • Maintaining normal testosterone levels in the blood and supporting normal fertility and reproduction. This is the foundation of your hormone balance.
  • Playing a role in cell division (important for recovery) and protecting cells from oxidative stress.
  • Ensuring a normal carbohydrate metabolism, an often underestimated factor for your energy supply during dieting and building phases.
  • Supporting the maintenance of normal skin, hair, and nails as well as normal vision.

Intake & flexibility of the tablet

Many users are surprised at first: "Why should I split it?" Quite simply: GN Laboratories has pressed an extremely potent 50 mg form here. Since that would be too much for daily continuous use for most people, the tablets have a practical score line.

Here is how to do it right: simply break it in half. The recommended daily dose is half a tablet. This already delivers the full 25 mg of active ingredient. That makes the container incredibly economical (price-performance winner).

If you are ever in an extremely hard competition prep, you have the flexibility to adjust temporarily, but for everyday use the half serving is absolutely potent enough.

Mentor tip for intake: The best time is in the evening or at some distance from meals. Avoid taking it at the same time as dairy products (calcium) or coffee, as these can inhibit absorption.

Quality promise – Made in Germany

With dietary supplements, trust is the currency. GN Laboratories produces this product in Germany according to the strictest standards (GMP & IFS certified).

That means: you get exactly what is stated on the label. No hidden hormones, no impurities, no animal-derived components. The product is 100% vegan (as no gelatin capsule shell is used) and comes without magnesium stearate as an anti-caking agent.

Frequently asked questions about Zinc Bisglycinate

What is the difference between zinc bisglycinate and the citrate form?
Both are organic forms with good absorption. However, bisglycinate is considered to be the "premium class" (chelate), as it is often better tolerated and absorption is less disturbed by other foods. Citrate is also solid - if you prefer this, you can find our citrate here. For maximum performance, we recommend bisglycinate.

Why do the tablets contain 25 mg zinc?
The product is primarily aimed at athletes and active people. Due to heavy sweating and an accelerated metabolism, the requirement here can be significantly above average. With 25 mg (1/2 tablet) you ensure that there is no shortage.

Is this zinc bisglycinate vegan?
Yes, absolutely. As these are tablets (and not capsules made from bovine gelatine) and no animal excipients are used, it is perfect for vegans.

How long does one can last?
That's the amazing thing about this product: as you only need half a tablet a day, one can (120 tablets) will last you a whole 240 days. That's 8 months' supply for a very fair price.
