For Buyers
ISTC LLC works with U.S. professional buyers seeking vitamins and dietary supplements. Share what your business needs so we can review the requirement and discuss possible next steps.

Retailers, distributors, healthcare-related businesses, e-commerce businesses, supplement businesses and procurement teams can contact ISTC about professional supply requirements. We serve business enquiries rather than consumer health or treatment questions.
Product details
Tell us the vitamin or supplement category, specific product, brand or formulation you seek. An exact product identifier helps when available.
Specification
Include preferred format, strength, ingredients, pack size or documentation needs where these are relevant to your purchasing decision.
Commercial needs
Share estimated quantity, intended market, target timing and any other requirements that could affect supply discussions.

Make the first discussion productive
When you know your required specifications, include them at the start. If you are still defining the requirement, explain the product category and intended business use. ISTC can then ask focused follow-up questions.
