No-one can say for sure what is "best". There is still much that is not known about the bioavailability and effectiveness of different NAD+ boosters. We believe that NMN have somewhat different effects on different tissues and organs, so we offer both. Sublingual likely delivers around 30% of NMN or NAD+ direct to the bloodstream. The nasal spray likely delivers a far higher %, direct to the brain, so a much lower dosage is used. But it probably doesn't reach beyond the brain to muscles and other organs as well as a sublingual tablet or powder.jocko6889 wrote: ↑Wed Jul 24, 2019 12:13 amIs the NAD+ Nasal Spray a better way to increase NAD+ than the NMN sublingual tablets? The assortment of products offered by ABM is a little confusing for me as to what are the 1-2 best products to take for optimal benefits. I ordered the complimentary nasal spray and hope to start using it soon. I used the NMN sublingual tablets and didn't notice too much difference but had no objective testing to verify any beneficial results.
The nasal spray I take to clear my mind and help me focus. I take it 4 times a day, first dose at 7:30 am rising, last dose about 8pm. It is used by Inhaling a couple of squirts up each nostril while closing the not being used nostril, breathing in and squirting. You really should take the time to read the astonishing research on it on the product page. I really believe I'm able to focus much more clearly without the "foggy"thinking I used to sometimes experience.
When i have used it, i can literally feel it in my blood stream in seconds.
Are people getting the same effect taking it sublingually?
Nasal delivery is also very effective because of the large mucosal surface area and the amount of vascular beds as well as the ability to bypass the blood brain barrier by using the olfactory and trigeminal nerve. I have included an article that discusses in detail the nasal delivery system and mechanisms used to increase delivery. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5760728/
