Product Reviews 

BioTonix BioBase 5-in-1 - R499.00

Review 

I’ve always preferred keeping my supplement routine simple, and the BioBase 5-in-1 makes that easier than ever. Instead of juggling multiple bottles, I now get everything I need in just three capsules a day — and I can genuinely feel the difference. This doctor-formulated stack covers all the essentials with Magnesium Bisglycinate, Buffered Vitamin C, Zinc Picolinate, Vitamin D3, and Vitamin K2 (MK-7), working together to support my immune system, energy, bone health, and overall vitality. What I really appreciate is how gentle it feels on my stomach while still being powerful and effective. It’s thoughtfully designed, clinically dosed, and formulated in the optimal forms my body can actually use. For me, it’s become an effortless, reliable way to stay consistent with my daily health routine — simple, smart, and effective.

BioTonix BioSpore Probiotic - R299.00

Review 

Finding a probiotic that actually works — without causing bloating or needing to live in the fridge — felt impossible until I tried BioSpore Probiotic. Formulated by Dr Terry Ann, this smart blend uses LactoSpore® Bacillus coagulans MTCC 5856, a clinically proven strain that survives stomach acid and gets to work where it matters most: the gut. Since adding it to my routine, I’ve noticed less bloating, better regularity, and an overall sense of digestive comfort and balance. It’s paired with Orafti® FOS inulin, a natural prebiotic that feeds the good bacteria, helping to maintain gut health over the long term. I also love that it’s shelf-stable, vegetarian, and travel-friendly — just one capsule a day is all it takes. It’s become my go-to for keeping my digestion and immunity steady, no matter how busy life gets.

BioTonix Bio B-Complex - R299.00

Review 

I started taking Bio B-Complex during a particularly stressful period, and it’s been such a lifesaver for my energy and focus. Formulated by Dr Terry Ann, it contains all eight essential B vitamins in their most active, bioavailable forms — including Magnafolate® C (a methylated form of folate) and Methylcobalamin B12 — so my body can absorb and use them effectively. Within days, I noticed a steady boost in mental clarity and stamina without that jittery feeling some supplements cause. It’s also made a real difference in my mood and stress levels; I feel more balanced and less fatigued by midday. I love that it’s gentle on the stomach, vegetarian-friendly, and even safe for pregnancy, making it something I can stick with long-term. It’s become my go-to daily essential for supporting brain function, energy, and overall well-being.

 

BioTonix Bio Omega-3 - R299.00

Review 

When it comes to supporting overall wellness, Bio Omega-3 feels like one of those quiet essentials that makes a real difference over time. Formulated by Dr Terry Ann, this double-strength marine oil delivers 600 mg of EPA and DHA in just one softgel — offering targeted support for brain function, heart health, and joint mobility. What sets it apart is its purity and precision: sustainably sourced, thoroughly purified, and completely free from fillers or oxidized fats. I’ve noticed improved focus, better energy, and a subtle sense of balance since introducing it into my daily routine. There’s no fishy aftertaste, just a clean, smooth supplement that truly delivers what it promises — advanced nourishment in its most effective form.

 

BioTonix BioFerrous Iron - R299.00

Review 

Iron supplements have always been tricky for me — most tend to upset my stomach — but BioFerrous Iron has completely changed that experience. Formulated by Dr Terry Ann, it uses Ferrochel® Iron Bisglycinate, a gentle, clinically tested form that’s easy to absorb and doesn’t cause constipation. I’ve noticed a real improvement in my energy levels and focus since taking it regularly. What makes it even better is the thoughtful combination of Magnafolate® C (active folate), methylated B12, and buffered Vitamin C, which work together to boost iron uptake and support healthy red blood cell formation. It’s vegan-friendly, safe for pregnancy, and genuinely delivers on its promise of raising ferritin without the unpleasant side effects. For anyone struggling with low iron or fatigue, this supplement makes feeling energised again simple and sustainable.

Naturmade Activated Charco Tabs - R159

Review 

Naturmade Charco Tabs have quickly become one of those essentials I like to keep on hand for those moments when my stomach just doesn’t agree with something I’ve eaten. Each tablet contains a precise dose of C-Extra® USP activated charcoal, known for its highly porous structure that gently binds gas and unwanted substances in the digestive tract. This helps ease bloating, cramps, and loose stools naturally — all without the charcoal entering the bloodstream. I also appreciate that they’re made in Europe in GMP-certified facilities, which gives me peace of mind about quality and safety. They’re small, convenient, and perfect for keeping at home, in your handbag, or even at the office, so quick relief is always within reach.

About Dr Terry Ann Serebro

I’m Dr Terry Ann Serebro, a qualified medical doctor with over 20 years of clinical experience—and a firm believer in science-backed, supplement-supported healing. For years, I’ve used targeted supplements in my integrative practice with exceptional results. From energy and immunity to gut health, hormone balance, and weight control, the right formulas at the right doses can be transformative.

But finding products that were effective, safe, and met my clinical standards wasn’t easy. My ethos has always been to provide patients with supplements that are safe, effective, and truly assist the body in healing itself. That’s why I began formulating my own—and curating only what’s proven to work, cutting out the fluff and hype.

The result is this site: a selection of products that reflect the same philosophy I use in practice every day. These aren’t gimmicks or general wellness fluff. They’re precise, practitioner-grade formulations designed to support real outcomes—whether you’re tackling fatigue, digestive issues, or simply want to feel better in your body.

As a doctor, I never recommend what I wouldn’t use myself or give to my own family. Every product listed here has been either formulated by me or selected based on real-world clinical results. It’s about combining rigorous science, personalisation, and care—now made more accessible, beyond the walls of my consultation room.

If you’ve ever wished your supplements actually made a difference, you’re in the right place.
