Walking into the supplement aisle — or scrolling through an online store — with three good options and no idea where to start is a genuinely common problem. NAD+, ashwagandha, and nerve support supplements all show up in searches for "best supplements for energy," "best supplements for stress," and "healthy aging supplements," which makes it easy to end up overwhelmed instead of informed. The truth is, these three supplement categories aren't competing with each other — they target completely different systems in the body. This guide breaks down exactly what each one does, who it's actually built for, and how to figure out which one deserves the first spot in your routine.

The Quick Answer: It Depends on Your Primary Goal

Before the deep dive, here's the fastest way to think about it:

• Low energy, fatigue, or interest in healthy aging? Start with NAD+.
• Chronic stress, anxiety, or trouble winding down? Start with ashwagandha.
• Tingling, numbness, or nerve discomfort in your hands or feet? Start with nerve support.

If more than one of these applies to you — which is common, since stress, energy, and nerve health are all connected — the sections below will help you prioritize, and the end of this guide covers how to eventually combine all three into one daily stack.

NAD+: Best for Cellular Energy and Healthy Aging

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell in the body, playing a central role in energy metabolism and cellular repair. NAD+ levels are well-documented to decline naturally with age, which is why NAD+ resveratrol supplements have become one of the most searched categories in the entire longevity and healthy-aging supplement space.

Choose NAD+ if you're dealing with:

• Low daily energy or fatigue that doesn't improve with sleep
• General interest in healthy aging and cellular health support
• A desire for a non-stimulant alternative to caffeine-based energy products

What to look for: a precursor-based formula (since raw NAD+ absorbs poorly on its own), a meaningful dose, and complementary ingredients like resveratrol and quercetin for antioxidant support and better absorption.

Ashwagandha: Best for Stress and Cortisol Support

Ashwagandha is an adaptogen — a category of botanicals traditionally used to help the body adapt to and regulate everyday stress. Clinical research shows ashwagandha supplementation can meaningfully reduce cortisol levels and lower measured stress and anxiety scores after consistent use, which has helped drive its rapid growth as one of the most popular herbal supplements on the market.

Choose ashwagandha if you're dealing with:

• Chronic or daily stress that feels hard to manage
• Trouble winding down or falling asleep due to a busy mind
• General interest in supporting a calmer, more regulated stress response

What to look for: a standardized extract with a specified withanolide percentage, a clinically relevant dose (typically 300–600mg), and a formula paired with black pepper extract (BioPerine) to improve absorption.

Nerve Support: Best for Tingling, Numbness, or Nerve Discomfort

Nerve support supplements are formulated specifically to support healthy nerve function and signal transmission, typically through ingredients like alpha lipoic acid and B vitamins. Unlike NAD+ and ashwagandha, which are broadly relevant to almost anyone, nerve support supplements are the most targeted of the three — built for people already noticing specific symptoms rather than general wellness maintenance.

Choose nerve support if you're dealing with:

• Tingling or "pins and needles" sensations in your hands or feet
• Numbness, especially at night or after sitting still
• Increased sensitivity to touch or mild balance issues

What to look for: alpha lipoic acid and B vitamins (especially B12) as core ingredients, clearly stated dosing rather than a proprietary blend, and — importantly — a conversation with your healthcare provider if symptoms are persistent, since nerve discomfort can sometimes signal an underlying condition worth ruling out.

Side-by-Side Comparison

Can You Take All Three Together?

Yes — and many people eventually do, since these three supplement categories target different systems rather than overlapping. Chronic stress affects energy metabolism, and both stress and low cellular energy can influence how well the body supports nerve health over time, so the three areas are more connected than they might first appear. The most common approach is starting with whichever category matches your most pressing concern, giving it a few weeks to assess how you feel, and then layering in the others as needed. We cover exactly how to structure this in our guide on building a daily supplement stack.

Where to Start: A Simple Decision Framework

If you're still not sure, ask yourself this one question: What's bothering me most right now — my energy, my stress, or a physical symptom like tingling or numbness?

Whichever answer comes to mind first is almost always the right place to start. From there:
