Frequently asked questions
What exactly is NAD+?
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell of your body. It is essential for turning nutrients into energy and repairing damaged DNA. As we age, our natural levels drop significantly, which is why supplementing can help restore youthful energy and mental clarity.
Why is an injection better than taking a pill?
When you swallow a supplement, much of the active ingredient is broken down by your digestive system before it reaches your bloodstream. The Crest Pharmacy injection pen bypasses the gut entirely, ensuring near-100% absorption so your cells get the full benefit of the 100mg dose.
Does the injection hurt?
We use ultra-fine, medical-grade needles designed for a virtually painless experience. Most users compare the sensation to a minor pinch. Because it is a subcutaneous injection (into the fatty layer of skin), it is much simpler and more comfortable than a traditional blood draw.
How quickly will I feel the effects?
While everyone’s biology is unique, many users report improved mental focus and higher energy levels within the first 24 to 48 hours. The benefits are cumulative, meaning they often become more pronounced after the third or fourth dose as your cellular levels stabilise.
Is Crest Pharmacy a regulated provider?
Yes. We are a fully regulated UK pharmacy. Our NAD+ is sourced and dispensed under strict pharmaceutical standards, ensuring that you receive a safe, high-purity product delivered directly to your door.
