NAD+ after 40: what it is and what to expect.
NAD+ is everywhere in wellness right now, from IV drips to gummies. Let's look at what it actually is, what's in this packet, and how to set realistic expectations.
What is NAD+?
Nicotinamide adenine dinucleotide is a coenzyme in every cell. It helps convert food into usable energy and supports enzymes involved in DNA repair. Research suggests levels drop with age, which is why it's become a healthy-aging favorite.
What else is in here?
TMG (trimethylglycine) is a methyl donor, often paired with NAD+ boosters. Apigenin is a plant compound from celery and chamomile being studied for helping your body hang on to NAD+. And there's a light 20 mg of caffeine.
From the product's Supplement Facts. Formulas can change, so check the box you receive.
Who might consider it
- Women 40+ curious about healthy-aging support
- Anyone who wants a light, low-caffeine boost
- People who already have the basics (sleep, protein, movement) covered
Before you buy
- Sensitive to caffeine? Take it in the morning, and count it toward your daily total.
- Pregnant or breastfeeding? There isn't enough safety data. Skip it.
- In cancer treatment? Talk to your oncology team before NAD+ products.
- Taking prescription meds? Have your pharmacist check it against your list.
A PharmD note: if your energy has crashed, get labs first. Low iron, low B12, thyroid changes and poor sleep are common, fixable causes in midlife. If you're not sure where to start, my free doctor questions guide can help you have that conversation.
