About the niacin flush
At 50mg, nicotinic acid commonly causes a temporary skin flush (warmth, redness, tingling) within 15-30 minutes of taking it. This is a normal, harmless histamine response and usually subsides within an hour. Starting with the capsule alongside food can help reduce its intensity.
What’s NOT in it
- No artificial colours, flavours, or sweeteners
- No GMOs, gluten, dairy, soy, or animal products
- Vegan capsule shell
Also good to know: both Fertility Advance and Fertility Focus contain B-vitamins as part of the preconception package. This standalone complex is for everyday energy support outside the preconception window.
