Founded by a scientist
Engineered, not marketed
Dr Elena Seranova holds a PhD in stem cell biology and autophagy from Birmingham. After years of research, she built NMN Bio because she couldn't find supplements clean enough to take herself.
Oh!Mg follows the same rule as every NMN Bio product: third-party tested, no fillers, no fluff. If she wouldn't take it, she wouldn't sell it.

Questions, answered straight
When should I take Oh!Mg?
30 to 60 minutes before bed, with water. Three capsules per serving. Taking it consistently — not just on rough nights — gives the formula time to compound.
Will it make me groggy in the morning?
No. Oh!Mg is not a sedative. The magnesium, L-Theanine and Lemon Balm work by lowering nervous-system arousal, so you sleep deeper and wake up clear-headed.
Is it safe with other supplements?
Generally yes — Oh!Mg pairs well with NMN, NAD+ and standard multivitamins. If you're on prescription medication (especially blood pressure or muscle relaxants), check with your doctor first.
Is it vegan and allergen-free?
Yes. 100% vegan capsules. No gluten, dairy, soy, GMOs, or artificial fillers. Made in the UK to GMP standards and third-party tested for purity.
Why three forms of magnesium?
Bisglycinate is the gold standard for absorption. Lactate is gentle on the gut and supports nerve signalling. Taurate crosses the blood-brain barrier and supports cardiovascular calm. Together they cover pathways one form alone can't.
Where does it ship from?
All Oh!Mg orders ship from NMN Bio's UK fulfilment centre. International shipping is available — see nmnbio.co.uk for current rates and zones.
