BIOVIT Zinc
Natural source: Guava Leaf
Guava leaf Zinc, built for immunity, beauty, and sports
The mineral with the broadest commercial reach in the BIOVIT portfolio. Zinc carries 18 EFSA-authorised health claims spanning immunity, skin, hair, nails, cognition, fertility, bones, vision, and testosterone, the highest count of any single nutrient. BIOVIT's extract from organically grown guava leaf (BI077 organic, BI092 natural) delivers 4,000 mg of Zinc per 100g within a matrix of naturally occurring polyphenols and flavonoids.
Organic and natural variants both GB and EU compliant, and direct one-to-one replacements for synthetic zinc oxide, zinc gluconate, and zinc sulphate across supplements, gummies, sports nutrition, and plant-based ranges.
Specified by leading UK manufacturers, with samples dispatched within a week and reformulation support included.

From supplements to meat replacements
Zinc's 18 EFSA claims mean it earns its place across more categories than any other single nutrient in the BIOVIT range. Three where guava-leaf Zinc delivers the strongest commercial pull.
Supplements
Capsules, tablets, and powders where Zinc's claim breadth carries the format. Sits comfortably in immunity, beauty, sports, men's health, and women's health stacks, with the negligible 0.0375 g inclusion rate leaving room for complementary nutrients.
Meat Replacements
One of the three priority nutrients in plant-based meat fortification alongside B12 and Iron. Guava leaf reads as food, not fortifier, on a category where shoppers increasingly scrutinise the back-of-pack.
Gummies
Pairs naturally with Vitamin C in immunity gummies, where the two together anchor the on-pack claim story. At 0.0375 g per portion, Zinc disappears into the gummy matrix without affecting set, texture, or finish.

Frequently asked questions
Common buyer and formulator questions on specifying guava-leaf Zinc, covering bioavailability, taste profile, sports nutrition relevance, and the full EFSA claim set.
Zinc was one of eight micronutrients measured in BIOVIT's 30-day human intervention trial at Swansea University (61 volunteers, UKRI-funded, led by Prof Richard Bracken). The trial confirmed equivalent bioavailability between the natural and synthetic groups across the nutrients measured, supporting the position that guava-leaf Zinc performs in line with synthetic zinc forms.
Zinc is involved in over 300 enzymatic reactions in the body, which translates into the broadest authorised claim set of any single mineral. The claims span immunity, skin, hair, nails, DNA synthesis, cognitive function, fertility, fatty acid metabolism, bones, vision, testosterone, and cell division.
At typical inclusion rates (0.0375 to 0.075 g per portion), guava-leaf Zinc is taste-neutral across most formats. That sidesteps the metallic and astringent profile commonly associated with synthetic zinc forms, particularly in beverages, dairy alternatives, and chewable applications.
"Organic guava leaf extract" for BI077, or "Guava leaf extract" for BI092. Both read as recognisable food ingredients, far cleaner than "zinc oxide", "zinc gluconate", or "zinc sulphate" on a label.
Yes. Zinc carries the EFSA claims for normal protein synthesis, maintenance of normal testosterone levels in the blood, and normal function of the immune system, all directly relevant to sports performance and recovery positioning. It is a core ingredient in BIOVIT's Sports Performance premix.
0.0375 g per portion for "Source of", 0.075 g for "High in". For a precise cost figure in your formulation, get in touch with the team.

Yes. Every wholesale order comes with full reformulation support from BIOVIT's Head of Nutrition, Eiméar Sutton RNutr MSc. That includes equivalence mapping against your incumbent zinc form, inclusion-rate modelling, and on-pack claim wording aligned to GB and EU regulation, at no extra cost.
Zinc contributes to the following EU-authorised health claims under EFSA Regulation (EC) No 1924/2006:
Protection of cells from oxidative stress
Has a role in the process of cell division
Normal DNA synthesis
Normal acid-base metabolism
Normal carbohydrate metabolism
Normal cognitive function
Normal fertility and reproduction
Normal macronutrient metabolism
Normal metabolism of fatty acids
Normal metabolism of vitamin A
Normal protein synthesis
Maintenance of normal bones
Maintenance of normal hair
Maintenance of normal nails
Maintenance of normal skin
Maintenance of normal testosterone levels in the blood
Maintenance of normal vision
Normal function of the immune system
Reformulation support is included
Every BIOVIT wholesale order comes with full technical reformulation support at no extra cost, giving your NPD and technical teams direct access to a qualified nutritionist from brief to production.
Eiméar Sutton (RNutr MSc), our Head of Nutrition, leads the technical work on every account: equivalence mapping against your incumbent synthetic, inclusion-rate modelling, on-pack claim wording aligned to GB and EU regulation, and the small details that decide whether a synthetic-to-natural switch lands cleanly on the production line.
The result: shorter development cycles, fewer reformulation rounds, and a finished product your commercial team can stand behind.
