Research-Supported Benefits:

Supports Cellular Health. A non-flushing form of vitamin B3, niacinamide is an antioxidant and NAD+ precursor that supports DNA repair and sirtuin activation. Niacinamide is an antioxidant, which fights oxidative stress and helps to repair DNA. (1)

Supports Energy Levels. Niacinamide is readily absorbed in the stomach and the small intestine, where it can be subsequently transported to tissues for the synthesis of NAD+ to help produce energy. (2)

Supports Skin Health. Niacinamide supports skin health through its actions as an antioxidant. It also increases the production of skin ceramides—healthy fats that strengthen skin barriers and lock in moisture—and boosts collagen production. (3)

Supports Joint Health. Niacinamide supports a healthier inflammatory response in the joints and boosts collagen production, leading to more flexibility, mobility and comfort. Research shows that adults with joint disorders who took niacinamide for 12 weeks had improved joint health by almost one-third compared to the control group. (4)

Supports Brain Health. Niacin deficiency is known to cause serious brain damage. Research suggests that niacinamide may be beneficial for protecting and supporting brain health and cognitive function with age because it protects against neuron damage and boosts NAD+ levels. (5)

  • Niacinamide vs. Niacin. Compared to other companies that typically use niacin, ProHealth Longevity uses niacinamide because the body doesn’t have to do extra work to convert niacin into niacinamide.
  • Doesn’t Cause Skin Flushing. Plus, high doses of niacinamide don’t cause skin flushing, like high-dose niacin products tend to do.
  • High Dosage. ProHealth Longevity’s Flush-Free Niacinamide contains 600 mg of niacinamide (as nicotinamide) per serving, which is 3,750% of the Daily Value for niacin. Competitors typically contain 500 mg.
  • Quality Manufacturing Practices. All of our products are manufactured in an FDA-registered, GMP-certified facility.
  • Third-Party Tested in the USA. Every batch is third-party tested in US laboratories to ensure the highest quality, purity and potency. Certificates of Analysis are available.

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot. Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable. The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold. The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.

Interesting
Format: Kindle
So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.

I’m a little disappointed.
Format: Kindle
I usually like Jillian West’s books but this one was missing a lot for me. The pregnancy didn’t come across as real. She’s on her feet for 12 hour days but is perfectly healthy at 8 months pregnant? Yet the week she moves in all of a sudden she’s not? She is planning on actually running during one of the plot buildups. But at 8 months pregnant that’s incredibly hard to do. The lack of breathing ability and lung space, the change in body center, mass, and gravity. All of it prohibits running, unless you’re an athlete this didn’t come off as at all realistic. I didn’t feel any connection with the alphas. There wasn’t any emotional connection. It could be because of the tense it was written in. But I didn’t get any deep feelings out of this. It came across as checking off boxes. Even the spicy scenes weren’t really believable for me. I wanted to see them fall for her, and it just kind of all fizzled. Even Bishop. One thing I did really like was the ending. I did not see it coming and I’m interested in reading book two because of it. But on the whole this book was mostly disappointing for me.
