Description of Oh!Mg

Oh!Mg is NMN Bio's evening magnesium blend, formally presented as Relax Dream Repair. It combines three magnesium forms with L-theanine, lemon balm, zinc, vitamin B6, and vitamin B5 in a three-capsule bedtime serving. The formula contains no melatonin, which may appeal to adults who want an evening routine without taking that hormone. The brand positions it for calm, muscle relaxation, sleep, and overnight recovery, but those outcomes remain individual and the product does not diagnose or treat insomnia, anxiety, restless legs, or magnesium deficiency. Persistent sleep problems deserve clinical evaluation.

Composition of Oh!Mg

The ingredient list names magnesium bisglycinate, magnesium lactate, magnesium taurate, lemon balm extract, L-theanine, vitamin B6, vitamin B5, zinc glycinate, a hydroxypropyl methylcellulose capsule, microcrystalline cellulose, and berry scent. The official page publishes every amount for the three-capsule serving: 240 mg of elemental magnesium from bisglycinate, 38.4 mg from lactate and 28.4 mg from taurate, for a stated total of 306.8 mg of elemental magnesium, plus lemon balm extract 50 mg, L-theanine 50 mg, vitamin B6 5 mg, vitamin B5 2 mg and zinc 2 mg.

  • Magnesium bisglycinate, lactate, and taurate.
  • L-theanine and lemon balm extract.
  • Vitamin B6, vitamin B5, and zinc glycinate.
  • Melatonin-free three-capsule evening serving.

Ingredient Sourcing and Origin of Raw Materials

NMN Bio states that its products are third-party tested and packaged in a UK facility certified to GMP and ISO 9001 standards. The Oh!Mg page does publish the individual active doses and the total elemental magnesium, but not the country of origin of each magnesium salt, the extract ratio for the lemon balm, or a public lot-specific certificate. Certification of a facility supports process quality but does not prove every sleep claim or replace the actual Supplement Facts panel. US shoppers should request the current label and confirm international product compliance before relying on a UK formulation.

How to Take Oh!Mg

Take three capsules in the evening, about 30 to 60 minutes before bedtime, according to the official direction. The page states 306.8 mg of total elemental magnesium for that serving, which is a substantial dose to check against your other sources. Taking it with a light snack may improve stomach tolerance, although the label should take priority. Do not add other magnesium or calming supplements automatically.

  • Take three capsules 30 to 60 minutes before bed.
  • Count the 306.8 mg of elemental magnesium per serving against any other magnesium you take.
  • Separate magnesium from medicines such as certain antibiotics, bisphosphonates, and thyroid hormone when a clinician or pharmacist advises.
  • Avoid driving if the blend causes drowsiness or reduced alertness.

Price and Where to Buy Oh!Mg

The official NMN Bio store displays $63.00 (£45.00) for one bottle on a one-time purchase. Subscription pricing starts at 17% off and multi-bottle discounts go further, but recurring terms and cancellation rules should be checked carefully. Cost per night depends on the capsule count in the bottle, since a serving is three capsules. US buyers should also account for shipping, taxes, and delivery time.

My Take on Oh!Mg

My assessment is based on the published formula. Combining gentle magnesium forms with L-theanine and lemon balm is conceptually coherent for an evening product, and the absence of melatonin is a clear differentiator. Dose transparency is in fact a strength here: the page publishes each active and a total of 306.8 mg of elemental magnesium, which is what makes a real comparison possible. Kidney disease, sedatives, medication timing, pregnancy, and persistent sleep symptoms require extra care. I would still not purchase on claims of deeper sleep alone, but the published formula does allow an informed comparison.

Magnesium supplements can cause diarrhea, nausea, or abdominal cramping, even when a form is marketed as gentle. Reduced kidney function can increase the risk of magnesium accumulation.

Lemon balm and L-theanine may add to the effects of sedating products in some people. A first trial should happen at home when reduced alertness would not create a hazard.

The berry scent is a sensory feature, not an active sleep ingredient. Shoppers with sensitivities should inspect the complete excipient and allergen statement on the package.

For a careful personal trial, record the exact serving, timing, tolerance, and any other products used at the same time. Oh!Mg should be judged against its current label and intended role, with the stated precautions reviewed before a recurring purchase.
