Food Blend

Also known as: Proprietary blend, Whole food concentrate, Nutritional yeast, Food-source complex

C
Evidence

Food blends are concentrations of whole foods or food byproducts designed to provide additional nutrients, cofactors, and phytonutrients in their naturally-occurring forms. They may include nutritional yeast, vegetable powders, fruit concentrates, or fermented ingredients.

Primary uses

  • Nutrient delivery via whole-food matrix
  • Bioavailability enhancement
  • B-vitamin cofactor provision
  • Phytonutrient support

How it works

  • Provides nutrients in food-state form
  • May contain natural cofactors enhancing nutrient utilization
  • Fermentation may increase bioavailability and create metabolites
  • Whole-food matrix supports nutrient absorption

Dosage

Typical range
Varies by product; typically 100-500 mg per daily serving in multivitamins
Timing
With meals
With food
With food; supports nutrient absorption
Duration
Ongoing as part of daily nutritional support
Special populations
Generally safe; individuals with yeast sensitivity should verify if nutritional yeast is included

Forms

  • Nutritional yeast· 70/100
  • Vegetable concentrate· 70/100
  • Fruit concentrate· 70/100
  • Fermented food powder· 70/100
  • Proprietary blend· 70/100

Safety

Common side effects

  • Rare; depends on specific ingredients
  • Possible allergic reactions if contains known allergens

Contraindications

  • Yeast sensitivity (if blend contains nutritional yeast)
  • Food allergies to included ingredients (proprietary formulas may not fully disclose all components)

Evidence notes

Moderate evidence supports the bioavailability benefit of whole-food-derived nutrients and fermented forms compared to synthetic isolates in some contexts. However, most 'food blends' are proprietary with limited transparency; specific efficacy depends on ingredient composition and concentration (typically dilute in multivitamins).

Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
