Understanding NRV

What is NRV?

NRV stands for Nutrient Reference Value — the daily amount of a vitamin or mineral that meets the needs of most healthy adults. It's set by the European Food Safety Authority (EFSA) and printed on supplement labels as %NRV. Think of it as the recommended daily target, not a maximum limit.

NRV replaces the older term RDA (Recommended Daily Allowance) still used in some countries. The values are largely harmonised across the EU under Regulation (EU) No 1169/2011.

Why %NRV matters on your supplement label

The %NRV tells you what proportion of the daily reference intake one dose delivers:

• 100% NRV — one dose provides the full daily reference amount
• 50% NRV — one dose provides half; your diet should supply the rest
• Over 100% NRV — common for water-soluble vitamins (C, B vitamins) where the body excretes excess; less common for minerals where long-term high intake needs care

Nutri-Leaf products and NRV values

Vitamin C 1000mg — 1250% NRV

This is a high-potency formula. Vitamin C is water-soluble — the body takes what it needs and excretes the rest. The 1250% NRV reflects the 1000mg dose against an 80mg reference value. High-dose vitamin C is well-tolerated by most adults.

Vitamin B Complex — varies by B vitamin

B vitamins are water-soluble with NRV values ranging from 1.1mg (thiamin) to 16mg (niacin). The B Complex delivers multiples of the NRV for most B vitamins — again, safe because water-soluble excess is excreted.

Immune Complex — 50–100% NRV for minerals

Zinc at 10mg delivers 100% NRV. Selenium at 50µg delivers 91% NRV. Vitamin C at 40mg delivers 50% NRV (complemented by the rose hip). These levels are designed to be safe for daily, long-term use alongside a balanced diet.

Skin Hair & Nails — balanced mineral levels

Zinc at 3.5mg (35% NRV) and copper at 1.0mg (100% NRV) are set at complementary levels. Biotin at 50µg delivers 100% NRV for this B vitamin specifically associated with skin, hair, and nail maintenance.
