NAD+ & Collagen Boost: Immune Support Supplement Review


This NAD+ supplement has been great!


It contains thirty days worth of easy to take capsules and is made in the USA. I love that it also contains hydrolyzed fish collagen as well! It’s beneficial to immune systems and in helping my body reset after an illness. I feel an overall increase in wellness after the two weeks I’ve been taking it, and I’m excited about my results so far.


I’ve noticed no side effects and appreciate the quality of this supplement.


It’s a nice value!


Vitamin Basics & Tips


Vitamin A plays crucial roles in maintaining vision, immune function, and cellular communication. While this review focuses on an NAD+ supplement, it's worth noting that vitamin A works synergistically with collagen for skin health. Dietary sources like sweet potatoes, spinach, and fish liver oils provide retinol (preformed vitamin A) and beta-carotene (a provitamin).


Unlike water-soluble vitamins, vitamin A is fat-soluble and stored in the liver, requiring balanced intake to avoid toxicity. The recommended daily allowance is 900mcg RAE for men and 700mcg RAE for women. It supports mucous barriers in eyes/lungs - particularly relevant to the review's immune system benefits.


Recent studies show vitamin A enhances NAD+ metabolism, connecting to the supplement's formulation. Collagen supplements often pair well with vitamin A for skin repair. Always consult healthcare providers when combining multiple supplements to avoid nutrient interactions.
