Zinc Bisglycinate – What is it and why does the form matter?

Zinc is one of the body’s most versatile minerals – involved in over 300 enzymatic processes and crucial for everything from the immune system to hormone production. Despite this, zinc deficiency is more common than many think, especially among active individuals with high energy requirements. The problem is not always the intake – it is the absorption. Not all zinc is absorbed equally effectively by the body, and the form plays a decisive role. Zinc Bisglycinate is a chelate form where the zinc is bound to the amino acid glycine, providing superior bioavailability and minimal stomach upset. In this guide, we walk through what distinguishes Zinc Bisglycinate from regular forms of zinc and why it matters.

What is Zinc Bisglycinate?

Zinc Bisglycinate is a chelated form of zinc where the mineral is bound to two molecules of the amino acid glycine. The chelate bond protects the zinc in the gastrointestinal tract and allows for more efficient absorption compared to inorganic forms like zinc oxide or zinc sulfate. Glycine acts as a carrier molecule that transports the zinc past the barriers in the gut that otherwise limit mineral absorption – the result is more zinc into the body, with less impact on the stomach.

Core Chelate® – the patented difference

Skytrition's Zinc Bisglycinate is developed with the patented Core Chelate® technology. It is not just a quality choice – it provides extra assurance regarding the purity, consistency, and bioavailability of the raw material from batch to batch. Each capsule contains 150 mg of Zinc Bisglycinate (Core Chelate®), which provides 30 mg of elemental zinc – 300% of the RI.

Core Chelate® is a well-defined and controlled chelated zinc raw material with documented stability. This means you know exactly what you are getting – every time. Read more about Skytrition's patented ingredients.

What does zinc contribute to in the body?

According to EU-approved health claims, zinc contributes to:

• Normal immune system function
• Normal testosterone levels in the blood
• Normal metabolism and recovery
• Normal protein and DNA synthesis
• Normal cognition and psychological function
• Maintenance of normal hair, nails, and skin
• Normal protection of cells against oxidative stress

Zinc and training – why active people need more

Training increases the body's need for zinc in several ways. Sweat contains zinc, which means that intense training leads to losses that need to be replaced. Furthermore, zinc is central to protein synthesis and muscle repair after training – processes that are crucial for recovery and muscle building.

Studies show that athletes and active individuals are at higher risk for suboptimal zinc levels, which can negatively affect both performance and the immune system. A well-absorbed zinc supplement like Zinc Bisglycinate (Core Chelate®) is therefore a logical choice for those who train regularly.

Signs of low zinc levels

Suboptimal zinc levels can manifest in several ways:

• Slow recovery after training
• Increased susceptibility to infection
• Fatigue and reduced energy
• Hair loss or brittle nails
• Impaired sense of taste and smell
• Hormonal imbalance (especially testosterone in men)

Note: these symptoms can have many causes. Consult a doctor if you suspect a zinc deficiency.

Zinc Bisglycinate vs. regular zinc – what is the difference?

Form	Bioavailability	Stomach impact	Recommended for
Zinc Bisglycinate (Core Chelate®)	High	Minimal	Daily use, sensitive stomach
Zinc Oxide	Low	May irritate	Budget products
Zinc Sulfate	Medium	May irritate	Medical use
Zinc Gluconate	Medium	Mild	Short-term use

Dosage and use

Recommended daily dose: 1 capsule taken with 3–5 dl of water. Each jar contains 60 capsules – enough for 2 months. Zinc can be taken at any time of the day, but avoid taking it at the same time as iron or calcium as these may compete for absorption. If you take multiple minerals – spread them throughout the day for best effect.

Is Zinc Bisglycinate right for you?

The product is suitable for you if you:

• Train regularly and want to support recovery and immune function
• Want to ensure optimal zinc intake with high bioavailability
• Have a sensitive stomach and want to avoid irritating forms of zinc
• Prioritize patented and well-defined raw materials

The product is intended for healthy individuals over 18 years of age. If you are pregnant, nursing, or taking medication – consult a doctor before use. Do not exceed the recommended daily dose; high doses of zinc over a long period can affect copper absorption.

Combine smartly

Zinc works synergistically with several other nutrients. Here are three classic combinations:

• Zinc + Magnesium Bisglycinate – a classic stack for the immune system, recovery, and hormonal balance. Magnesium supports muscle function and sleep, while zinc supports testosterone and the immune system.
• Zinc + D3/K2 – zinc and vitamin D work together in the immune system. K2 ensures that calcium is correctly utilized in the body. A complete foundation for immune function and bone health.
• Zinc + Vitamin C – a classic immune combination, especially relevant during autumn and winter or during intense training periods.

Frequently asked questions

What is Zinc Bisglycinate?

A premium zinc supplement where the zinc is bound to the amino acid glycine via the patented Core Chelate® technology for superior bioavailability and minimal stomach upset.

Why is Core Chelate® better than regular zinc?

Core Chelate® is a patented chelate technology with documented stability and bioavailability. Unlike cheaper forms like zinc oxide, the chelate form is absorbed efficiently in the gut and is gentle on the stomach. Read more about Skytrition's patented ingredients.

How much zinc does each capsule contain?

Each capsule contains 150 mg of Zinc Bisglycinate (Core Chelate®), which provides 30 mg of elemental zinc – 300% of the RI.

Is 30 mg of zinc per day safe?

Yes, for normal daily use of 1 capsule. Do not exceed the recommended daily dose. High doses of zinc over a long period can affect copper absorption.

When is the best time to take zinc?

Zinc can be taken at any time of the day. Avoid taking it at the same time as iron or calcium as these may compete for absorption.

Can I combine Zinc Bisglycinate with Magnesium Bisglycinate?

Yes. Zinc and magnesium complement each other well and are a classic combination for immune function, recovery, and hormonal balance. Read more about Magnesium Bisglycinate with Core Chelate®.

Can I take zinc if I train hard?

Yes – active individuals often have an increased need for zinc due to losses through sweat and increased turnover in connection with training and recovery. Zinc Bisglycinate is an excellent choice for those who train regularly. Also see RestUP for optimized recovery and sleep.

What is curcumin and how does it relate to zinc?

Curcumin is the active substance in turmeric with powerful anti-inflammatory properties. Combined with zinc, it provides broad support for the immune system and recovery. Read more about curcumin and CurcuUP.
