Frequently asked questions
Practical answers to the questions buyers and formulators ask most when specifying natural calcium - bioavailability, declaration, formulation, and certifications.
Equivalent. The Swansea University human intervention trial (61 volunteers, 30-day intervention, eight blood markers) confirmed BIOVIT’s natural calcium delivers bioavailability comparable to synthetic calcium sources. The whole-food matrix means brands gain a clean-label declaration without trading off absorption.
“Organic algae extract” for BI090 and “Algae extract” for BI091 - both immediately recognisable to shoppers. 73% of UK consumers expect everyday products to contain only natural vitamins and minerals, and a recognisable plant or algae source on the ingredient panel does that work directly.
0.375 g per portion delivers a ‘Source of’ calcium claim (15% RI), and 0.750 g per portion delivers ‘High in’ (30% RI). Inclusion rates are very small and easy to manage, with per-unit cost impact for finished products typically around 1% of cost of goods. Eiméar will model the exact figure for your formulation.
Yes. Every batch is tested by ICP (Inductively Coupled Plasma) for calcium content and the trace mineral profile, with certificates of analysis issued against fixed specifications. The natural variability of any harvested ingredient sits within tolerances tighter than most botanical extracts.
Samples are dispatched within a week of request. Commercial orders are typically fulfilled in around 3 weeks from confirmed PO. Minimum order quantity is 1 kg for trials, with bespoke formats available on request.
Yes. Reformulation support is included in every BIOVIT consultancy. Eiméar Sutton (RNutr MSc) handles the technical work - equivalence mapping, inclusion-rate modelling, stability testing where needed, and updated on-pack claim wording — so the switch lands without disrupting your production schedule.
Calcium has 10 UK-valid EFSA-approved health claims (8 adult claims and 2 children's claims), each requiring at least 15% of the Reference Intake (RI) per portion.

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.
