What is NutriBiotic?

NutriBiotic was established in the early 1980s with a simple idea: to make clinically inspired, affordable nutritional supplements that follow the science on vitamin C, antioxidants, and natural plant extracts. The brand is heavily influenced by research into vitamin C’s role in immune defence and tissue repair, and it quickly became recognised for its pharmaceutical-grade vitamin C powders and innovative grapefruit seed extract (GSE) products.

Over time, NutriBiotic expanded into plant-based rice protein, immune sprays, ear drops, tablets & capsules, nasal care and skin ointments, but the core philosophy remains the same: minimal unnecessary excipients, allergen-conscious formulations and straightforward, label-transparent products. So, explore our website for NutriBiotic products today.

Benefits and features of the nutriBiotic collection on Welzo

High-quality vitamin C: NutriBiotic products have ascorbic acid and sodium ascorbate. They are flexible to use and provide strong antioxidant support.
Pure grapefruit seed extract: NutriBiotic supplements use carefully standardised grapefruit extract. It is effective for immunity, gut health, and skincare applications.

Clinically supported formulations: NutriBiotic products have a clear purpose—immune resilience, gut balance, skin defence, and ear hygiene. It makes it different from generic multivitamin blends.

What makes NutriBiotic so important for everyday health?

Modern lifestyles place constant pressure on immune function, skin barrier health, and mucosal defences (ears, nose, throat, and gut). NutriBiotic supports these functions in the body.

Immune defence: This collection has vitamin C, zinc-containing throat sprays, and antioxidant-rich GSE products. They maintain day-to-day immune resilience.
Microbial balance in the gut: Grapefruit seed extract improves digestive balance. It also facilitates microbial control when used with probiotics.
Skin support: This collection has ointments and cleansers. They combine GSE, lysine, and vitamins and protect skin from irritation.
Ear and nasal care: Gentle ear drops and sprays provide a more “natural leaning” option for those looking to support ear comfort and upper-respiratory health.

How to use NutriBiotic supplements & personal care products?

NutriBiotic products are straightforward to use. Here are guidelines for each product type.

Vitamin C powders: Mix them with water or juice and use daily with food. They adjust with our immunity-support supplements for daily defence.
Grapefruit seed extract liquids: We recommend following the label instructions. Stick to them for both topical and internal use.
Ear drops: Tilt your head and apply the drops as directed. Keep your head inclined for the suggested time. We have similar products in our ear care collection.
Skin ointments and cleansers: Apply cleansers & ointments as thin films on clean skin. Use a skin patch test in case of sensitive skin.
Throat and nasal products: Follow label instructions. Never use them on a long-term basis unless advised.

Pregnant and nursing women and people using medications must consult a doctor. Our blog titled 'First Step for Nutrition' can help eliminate your doubts.

Statistics, research & expert insight on NutriBiotic

NutriBiotic has been associated with vitamin C and GSE innovation for over four decades. The brand is strongly linked to the rise of high-dose vitamin C as a daily wellness tool and helped establish grapefruit seed extract as a widely used plant-derived ingredient in the natural health space. Many NutriBiotic products have become staples in integrative clinics and health stores worldwide, particularly among people seeking allergen-conscious, cruelty-free formulations.

Vitamin C deficiency causes scurvy in children. According to NHS England Digital, it is a rising threat in the UK, and its status has changed from rare to noticeable.
