Nutritional & Functional Ingredients

Explore nutritional and functional ingredients for supplement, food and beverage development. This directory brings together amino-acid-related materials, vitamin derivatives, named microbial strains, protein and peptide ingredients, specialty materials and marine-derived products. These groups are not interchangeable: each needs a different identity check, specification and documentation review before it can be assessed for a formula.
Start an inquiry with the exact material name, intended application, target grade and destination market. For an amino acid or vitamin derivative, specify the form and assay basis you need. For a probiotic, identify the strain rather than relying on species alone, and ask about the current specification and handling requirements. For protein, peptide or marine materials, clarify source and any origin or allergen restrictions relevant to your project. We can confirm which listed grade, current-batch COA and supporting documents are available for review; do not assume one product’s documentation covers another.
Compare representative ingredients:

5-HTP Powder 98% and N-Acetyl-L-Cysteine Powder 99% show two distinct amino-acid-related purchasing specifications.
Pyridoxal-5-Phosphate Powder 98% and Vitamin K2 (MK-7) Powder 1.0% illustrate why the exact vitamin form and grade matter.
Bifidobacterium breve HC2953 Freeze-Dried Powder and Lactoferrin Powder 95% require different identity and handling questions.
Sunflower Lecithin Powder PC20, Alpha Lipoic Acid Powder 99% and Salmon Collagen Peptide Powder broaden the source and format comparison.

Before requesting a quotation, send the specification or formulation brief your quality team will use to approve the ingredient. Include any source, assay, microbial, allergen or packaging requirement that could rule out a grade. That lets us discuss available options and documents against a real purchasing decision, rather than a broad category label. Send your target ingredient and qualification requirements.
