NatroVital ZSIM Capsules

  • NatroVital ZSIM Capsules combine zinc, selenium, iodine, and magnesium—four key minerals valued for their wide-reaching roles in supporting everyday health. Each one plays a part in keeping essential body systems running smoothly, including immune defences, thyroid activity, skin integrity, brain function, energy production, and reproductive health.

    Each capsule contains 100% pure active ingredients with absolutely no binders, fillers or synthetic additives. This clean, simple formulation is designed to deliver the minerals your body needs, support optimal absorption, and leave out anything unnecessary.

    How NatroVital ZSIM Supports Your Health

    • Immune Support: Zinc, selenium, iodine, and magnesium work in combination to help maintain healthy immune function, assisting the body’s ability to adapt to seasonal changes and handle everyday environmental challenges.
    • Hormonal Health: Iodine, zinc, selenium, and magnesium each play a role in reproductive health and in the natural production of hormones that influence menstrual cycles, fertility, mood, and energy for both men and women.
    • Thyroid Function: These minerals contribute to the normal production and regulation of thyroid hormones, which are essential for managing metabolism, energy balance, and temperature control.
    • Skin Health & Recovery: Zinc, selenium, and magnesium help maintain skin strength and elasticity, assist in tissue repair, and support the healing of minor cuts, scrapes, and blemishes.
    • Cognitive Function: Zinc, selenium, magnesium, and iodine are involved in processes linked to memory, focus, mental clarity, and learning ability.
    • Reproductive Function: Zinc and selenium support healthy sperm and egg development, while iodine and magnesium assist with hormone regulation connected to fertility.
    • Muscle & Nerve Function: Magnesium, zinc, and selenium work together to support smooth muscle movement, relaxation, and reliable nerve signalling for coordination and performance.
    • Bone Health: Magnesium, zinc, and iodine help maintain bone density and strength, supporting mobility, posture, and long-term skeletal wellbeing.
    • Hair Health: Zinc, selenium, and iodine help keep hair follicles healthy to support normal growth, strength, and texture.
    • Antioxidant Support: Selenium, zinc, and magnesium form part of the body’s antioxidant defence system, helping protect cells from damage caused by factors such as an unbalanced diet, environmental pollutants, intense exercise, and the natural ageing process.
    • Energy Production: Magnesium, zinc, and iodine assist in converting food into usable energy, helping to maintain stamina throughout the day.
    • Blood Sugar Support: Magnesium, zinc, and selenium contribute to maintaining stable blood sugar levels, supporting consistent energy and appetite control.
    • Allergy Support: Zinc, selenium, and magnesium help maintain a balanced immune response to everyday environmental triggers, including pollen, dust, and pet dander.

    What We Often Combine with NatroVital ZSIM in Clinic

    In clinic, we often pair NatroVital ZSIM with other NatroVital formulas to complement its mineral support and enhance overall wellbeing. For example:


    Why choose NatroVital over other supplement brands?

    NatroVital is a proudly Australian-owned and operated business, founded by Greg Newson—a qualified naturopath, herbalist, and nutritionist with over 20 years of clinical experience. Our range was created out of frustration with the supplement industry, where too many products were filled with synthetic binders, fillers, flavours, and unnecessary additives that compromise quality and efficacy.

    We believe what’s left out is just as important as what goes in. Every NatroVital product, including ZSIM, is formulated without synthetic additives, binders, fillers, or artificial preservatives. Instead, we use clean, functional ingredients that deliver nutritional support without compromise.

    All NatroVital products are developed and produced in small batches at our own facility in Australia. As a family-run business, we are committed to creating honest, effective, practitioner-formulated supplements you can trust.

    Does NatroVital ZSIM contain any fillers, preservatives or artificial additives?

    No. NatroVital ZSIM contains only 100% pure active ingredients in a vegetable capsule. It is completely free from binders, fillers, additives, colours, preservatives, and anything artificial.

    Is NatroVital ZSIM suitable for vegans and vegetarians?

    Yes. NatroVital ZSIM contains no animal-derived ingredients, making it fully suitable for both vegans and vegetarians.

    Are there any contraindications or situations where NatroVital ZSIM should be avoided?

    Avoid using NatroVital ZSIM if you are allergic to any of its ingredients.

    Some people may experience nausea when taking zinc on an empty stomach. If this occurs, take the morning capsule after lunch instead of after breakfast.

    Caution is advised if taking antibiotics such as Ciprofloxacin, Doxycycline, or Tetracycline, as zinc and magnesium may reduce their absorption and activity. Take ZSIM at least 2 hours apart from these medications.

    Zinc may lower blood sugar levels, so extra care is needed if you are also taking antidiabetic medication.

    If you are on Ritonavir or Atazanavir, be aware that zinc may reduce serum ritonavir levels by binding to it in the gut and limiting absorption.

    Do not take NatroVital ZSIM if you are currently using antithyroid medication.

    Is NatroVital ZSIM a therapeutic medicine?

    NatroVital ZSIM is a practitioner-formulated nutritional supplement containing zinc, selenium, iodine, and magnesium—nutrients recognised for their role in supporting general health and wellbeing. It is not listed with the Therapeutic Goods Administration (TGA) and is not intended to diagnose, treat, cure, or prevent any medical condition.

    In Australia, only products listed or registered with the TGA are permitted to make therapeutic claims. We refer instead to the recognised role of these nutrients in supporting healthy body systems. If you’re unsure whether this supplement is right for you, please speak with your healthcare provider.

    Why isn’t NatroVital ZSIM listed with the TGA?

    We’ve chosen not to list ZSIM with the Therapeutic Goods Administration (TGA) so we can speak more openly about the recognised role of nutrients in supporting everyday health. TGA listing requires strict language restrictions, significant regulatory costs, and licensed manufacturing—factors that can reduce flexibility and increase product prices.

    By remaining AustL-exempt, we can formulate and produce in small batches, keep pricing affordable, and stay true to our commitment to clean, transparent, practitioner-designed supplements without unnecessary fillers or additives.

    At Vitality and Wellness, we believe supplements should work with your body—not against it. That’s why every product we stock is selected with care, guided by clinical experience, and included because it meets a standard we’re comfortable recommending. While some formulas may include common excipients, we always prioritise cleaner, practitioner-quality options—like the NatroVital range—where purity, effectiveness, and transparency come first.
