Beta-Carotene

Provitamin A Natural Algal & Synthetic Dunaliella salina E160a Colourant CAS 7235-40-7
The provitamin A carotenoid that converts to retinol on demand — safe at any supplemental dose, impossible to overdose, and backed by decades of clinical data on immune support, skin health, and vision.
Beta-carotene is the body's preferred way to maintain vitamin A status when dietary preformed retinol cannot be safely supplemented — in pregnancy, childhood, and populations at overdose risk. The intestinal enzyme beta-carotene-15,15'-dioxygenase converts beta-carotene to two molecules of retinol, but only when the body needs it. When vitamin A stores are replete, conversion slows to as little as 1:28. This self-regulatory mechanism is unique to provitamin A carotenoids and is the reason no tolerable upper intake level has been set for beta-carotene in non-smokers.

SV Botanica supplies natural Dunaliella salina algal beta-carotene (containing the full cis/trans isomer spectrum), palm-source concentrates, and synthetic water-dispersible beadlets — covering oil suspension grades for softgels and water-dispersible grades for tablets, beverages, and powder blends.

  • Oil suspension versus beadlet — the whole formulation decision. The oil grades need a lipid matrix and refrigerated handling; the beadlet is water-dispersible and stable at ambient, which is why beverage and tablet formats normally specify it.
  • Natural versus synthetic — the Dunaliella salina and palm-source grades support a natural declaration; the beadlet is synthetic. They are not interchangeable on a botanical or natural label, so specify which you require at enquiry.
  • Assay basis differs sharply — 20% or 30% in the oil suspension against 10% in the beadlet matrix. Confirm which basis your specification is written against before comparing quotations on price per kilo.
  • Cold chain for oil grades — refrigerated shipping is available and the 18-month shelf life assumes it. The beadlet grades ship ambient with a 24-month shelf life.
  • Colour carry-through — deep orange in the oil grades. It carries into the finished format and will tint an oil base or a softgel shell at low inclusion.
  • Mixed-carotenoid grade — a natural alpha plus beta-carotene blend from algae, specified where a broader carotenoid profile is wanted rather than beta-carotene alone.
  • Packaging — 5 kg and 25 kg sealed containers with nitrogen headspace for oil suspension grades, and 1 kg and 5 kg light-protected aluminium foil bags for beadlets. Custom concentrations available.
  • Documentation — each batch ships with a CoA covering assay against the stated grade, heavy metals at NMT 10 ppm with lead at NMT 0.5 ppm, moisture at NMT 2.0% for the beadlet form, microbial limits, and a source declaration for the natural grades.

Formulation Intelligence

Beta-Carotene Buyer's Guide: Natural vs Synthetic, Safe Dosing & Form Selection

Beta-carotene occupies a unique regulatory position — it is simultaneously a nutrient, an antioxidant, and a natural food colourant (E160a), making it one of the few nutraceutical ingredients used across supplement, food, and cosmetic categories. Specifying the right grade and form for the application is straightforward once the three key decision points are understood.

Natural Grade

Dunaliella salina Algae

CAS 7235-40-7 · ~50% all-trans + ~50% 9-cis

Deep orange oil suspension (20% or 30%). Supports "natural beta-carotene" or "from Dunaliella salina algae" label claims. Co-occurring alpha-carotene and xanthophylls provide a full carotenoid spectrum. Research suggests 9-cis isomers may have distinct antioxidant and biological activities not present in all-trans synthetic.

Best for: premium natural supplements, women's health, prenatal formulations.
Synthetic Grade

All-Trans Crystalline / Beadlet

>97% all-trans · Oil suspension or 10% beadlet

Available as oil (for softgels) or water-dispersible beadlet 10% (for tablets, beverages, and powders). Lower cost than natural algal grade. No "natural" label claim possible. Identical biological activity to all-trans natural in the dominant isomeric form. Excellent stability in beadlet matrix form.

Best for: food fortification, beverages, multivitamins where "natural" positioning is not required.
Dosing Safety

Standard vs High-Dose

Safe: 2–6 mg/day · Caution: >20 mg/day in smokers

For vitamin A equivalence in multivitamins: 2–6 mg/day corresponds to the RDA equivalent. Published safety literature reports an increased lung-cancer incidence among heavy smokers taking high-dose beta-carotene in the ATBC and CARET trials, and several markets restrict or require warnings on high-dose products as a result. Finished-product manufacturers should review the current safety literature and their market's requirements when setting inclusion levels and target populations. Documented risk. Label guidance for smokers required at high-dose formulations.

Note: No upper tolerable intake set by EFSA for non-smokers at standard supplement doses.
Form Selection

Oil vs Beadlet

Oil for softgels · Beadlet for tablets, powders, beverages

Oil suspension (20–30%) for softgels — best bioavailability when consumed with dietary fat. Beadlet 10% for tablets, powders, and beverages — water-dispersible for flexible manufacturing. Regardless of form, beta-carotene absorption requires co-ingestion with fat. Include vitamin E for shelf life stability.

Note: Softgels with vegetable oil excipient = maximum bioavailability delivery.
Buyer FAQ

Frequently Asked Questions

A 20% natural grade from Dunaliella salina algae in oil suspension, a 30% palm-source concentrate, a 10% synthetic water-dispersible beadlet for beverages and tablets, and a natural alpha plus beta-carotene mixed-carotenoid blend from algae.
The beadlet where the format is aqueous or dry — it is water-dispersible and ambient-stable with a 24-month shelf life. The oil suspension where a lipid matrix already exists, such as a softgel; it needs refrigerated handling and carries an 18-month shelf life.
Not on a label. The Dunaliella salina and palm-source grades support a natural declaration; the beadlet is synthetic. Assay basis also differs — 20% or 30% in oil against 10% in the beadlet matrix — so they are not comparable on price per kilo either.
Assay against the stated grade, heavy metals at NMT 10 ppm with lead at NMT 0.5 ppm, moisture at NMT 2.0% for the beadlet form, microbial limits, and a source declaration for the natural grades.
Deep orange viscous oil for the natural suspension grades; orange water-dispersible beadlets at 20–40 mesh for the synthetic grade. Shelf life 18 months refrigerated for the oil, 24 months cool and dry for the beadlet.
Yes. Deep orange in the oil grades, and it will tint an oil base or a softgel shell at low inclusion. This is a consideration for clear or lightly coloured presentations, and is also why the material is used as a colouring ingredient in its own right.
Formats where a broader carotenoid profile is wanted rather than beta-carotene alone. It is a natural alpha plus beta-carotene blend from algae.
5 kg and 25 kg sealed containers with nitrogen headspace for the oil suspension grades, and 1 kg and 5 kg light-protected aluminium foil bags for the beadlet grades. Refrigerated cold-chain shipping is available for oil suspension grades.
Against your specification and volume. Grade, concentration, natural versus synthetic and cold-chain requirements all move the price.
