How to choose within this range
| Your requirement | Specification to fix | Why |
|---|---|---|
| Dry blending | A powder or adsorbate grade | Oils and crystals are not directly blendable in dry premixes |
| Oil-based formulation | The oil grade at the required MIU/g | Potency per gram determines dosing and overage |
| High-potency premix | A crystal or high-dilution grade | Handling, weighing accuracy and dust control differ by form |
| Comparing quotations | Match physical form and potency basis first | The same vitamin name can cover several forms with different economics |

Frequently Asked Questions
Why are the same vitamins listed at different potencies?
Because the industry supplies the same vitamin as a crystal, an oil, and diluted powder or adsorbate forms. Each has a different potency, carrier and handling requirement.
Which form should I choose?
Match the form to your process: dry blending uses powders or adsorbates, oil-compatible systems use the oil grades, and high-potency premixes use crystals or high-dilution grades.
How is potency expressed?
As a percentage, as IU/g or MIU/g, or as a stated dilution. The basis is declared on each product page so grades can be compared consistently.
What stability information should I ask for?
Request the current COA, the carrier system and any available stability data for light, heat and oxygen exposure in your intended packing.
Are you a manufacturer or a trading company?
We are Shaanxi Longsheng Biotechnology Co., Ltd., a direct manufacturer integrating R&D, production and export support. Factory review may be arranged by video or an on-site visit.
Can I request the current batch COA before ordering?
Yes. Request the applicable current or representative COA for each shortlisted grade and compare identity, method, limits and results.
What is the minimum order quantity?
The regular MOQ is typically 1 kg. Evaluation samples of 10-20 g may be arranged subject to stock.
Can specifications or packaging be customised?
Selected assay targets, particle size, carrier and packing may be reviewed case by case before quotation.
