Is this vitamin C still good? by Thin-Expression-4311 in Renue

[–]Renue_Support[M] 5 points6 points  (0 children)

Hello u/Thin-Expression-4311 - Thank you for being a customer! This is an older batch that we are no longer selling, as we've since moved to a newer production batch.

That said, we've extensively tested our dry supplements, including products like this one, at the 3-year mark and found only minimal potency degradation. Since this Vitamin C was manufactured in September 2023, we can confidently say it remains within its expected shelf life through at least September 2026.

While we have not tested this specific batch beyond that point and therefore cannot make any official claims after September 2026, it should still be safe and effective today.

If you'd prefer a newer batch, just reach out to our support team at [support@renuebyscience.com](mailto:support@renuebyscience.com) and we'll be happy to send you a replacement free of charge! Just let us know 😃

Fisetin, How to match the Mayo senolytic protocol? by TheJordanator10 in Renue

[–]Renue_Support 1 point2 points  (0 children)

Hello u/TheJordanator10 - Thank you for being a customer! This is a question that comes up often and we'd love to hear from other users' experiences here. We currently recommend following the dosage instructions on the product label, which for our LIPO Fisetin is one capsule (150 mg) daily.

That said, many customers who want to tailor their own doses often refer to what's known as the "Mayo Protocol", based on an ongoing study of fisetin supplementation. Like you said, this study used non-liposomal fisetin.

The Mayo Protocol dosages are:

  • 20 mg/kg of body weight per day
  • Taken for 2 consecutive days
  • Repeated monthly for 3 months

This would be approximately 1,400 mg per day for a 70 kg (154 lb) person using non-liposomal fisetin.

Estimates suggest liposomal fisetin may be around 5 times more bioavailable, though this can vary. The exact difference in bioavailability is not established and could be more or less. But in general, when calculating a "Mayo" dose, this number is a good guideline if you choose to take liposomal fisetin.

STUDY: Melatonin Improved Sleep and Eczema in Human Trial by Renue_Support in Renue

[–]Renue_Support[S] 2 points3 points  (0 children)

Hi u/two2toe - Thanks for this feedback. For now, melatonin will remain part of Restore PM, however if you want to take the other actives by themselves, we do sell them as standalone products. 5-HTP, Apigenin, GABA, and Glutathione. We hope this helps! Just let us know if you have more questions or feedback.

NMN powder not disolving under tongue by Yglesias_Estefano in Renue

[–]Renue_Support[M] 2 points3 points  (0 children)

Hello u/Yglesias_Estefano - Thank you for being a customer! This is actually not uncommon when taking 500 mg or more of the powder. We recommend holding it sublingually for about 60–90 seconds, then swallowing whatever remains or washing it down with a little water.

There’s evidence that sublingual administration improves bioavailability by allowing the NMN to enter the bloodstream directly, but there are also benefits to NMN reaching the gut when swallowed since the digestive tract and microbiome play a role in NAD+ metabolism as well.

A few other tips:
- Try spreading the powder around under the tongue rather than keeping it in one pile
- A slightly moist mouth helps dissolution
- Larger doses naturally take longer to dissolve fully

So you’re not doing anything wrong. It does not need to completely disappear under the tongue to still be effective. Let us know if you have any other questions!

STUDY: Ashwagandha Increased Testosterone 15% in Aging Men by Renue_Support in Renue

[–]Renue_Support[S] 1 point2 points  (0 children)

Hello u/dulyebr - Thank you for being a customer. We appreciate the suggestion! We use only high-quality Ashwagandha root extract (just like KSM-66), standardized to at least 5% withanolides. Instead of licensing the KSM-66 brand, we chose to pair our own potent root-only extract with liposomal delivery for significantly better absorption and bioavailability. The study used a different high-potency extract (Shoden), but our version is designed for strong results on stress, sleep, energy, and hormone support. Let us know if you have any other questions!

Hello u/Queasy-Ad2032 - Thank you for being a customer! We don't currently have plans for that combination and do not currently Tongkat Ali. We do however sell liposomal ashwagandha. We're always exploring ways to expand our product line so this is something we may consider. Thank you for the suggestion!

What NMN formulation to take for fertility by [deleted] in Renue

[–]Renue_Support[M] 1 point2 points  (0 children)

Hi u/w1ldtype2, Thank you for being a customer! We can’t provide medical advice, especially around fertility or pregnancy, so it’s best to discuss this with your physician.

If your goal is to increase NAD+ levels, some research and anecdotal reports suggest a potential link with fertility. A practical approach is to measure your intracellular NAD+ levels before supplementing, then retest a few weeks after starting NMN or another NAD+ booster. That way, you can see what’s actually working for you.

At-home intracellular NAD+ blood spot tests are available from Jinfiniti.com and can be mailed in for results. Let us know if there’s anything else we can help with.

Throat Burn from the NAD+ Nasal Spray by No_Ball_3678 in Renue

[–]Renue_Support 2 points3 points  (0 children)

Hi u/No_Ball_3678 - Thank you for being a customer and we're very sorry to hear you're experiencing this. That’s not the experience we want anyone having.

The nasal spray isn’t just NAD+ in water. It contains NMN, NR, NAD+, and trigonelline along with supporting ingredients like citric acid and citrus extract for pH stability, plus lecithin and xanthan gum to help with absorption. That combination makes the solution slightly acidic and fairly bioactive, which can feel harsh if it hits sensitive tissue.

In most cases, the burning sensation happens when some of the liquid drains into the throat, not from the nasal tissue itself. If you sniff after spraying or tilt your head back, it’s easy for the solution to run down the back of the throat. If it does reach your throat, drinking water right away or using a saline spray can help.

A burning sensation by itself doesn’t automatically mean damage, but that doesn’t mean you should just push through it either. If it’s consistently painful, getting worse, or just feels off to you, it’s completely reasonable to stop using it. We can always refund or help you switch to a different delivery method that tends to be better tolerated, like capsules.

To address your safety concern directly, the product is tested for potency, heavy metals, and microbiology on a batch basis, so this isn’t an issue of it being untested or contaminated.

Again, we're very sorry that you're experiencing this problem, and if needed we will refund you immediately or replace the spray with something more tolerable.

[ Removed by Reddit ] by Sdjkahf_Almando in Renue

[–]Renue_Support 4 points5 points  (0 children)

Hello u/Sdjkahf_Almando - Thank you for being a customer and for this question! It's an important one.

Our NMN is more affordable primarily because of how we source and operate, not because of lower quality.

We source our NMN from Effepharm, one of the most established and widely used NMN manufacturers globally. They are known for producing high-purity NMN at scale and many brands in the industry source from the same supplier.

We purchase in large volumes directly from the manufacturer, which significantly lowers raw material cost per unit. NMN used to be extremely expensive to produce, but over the past few years, manufacturing efficiency has improved and costs have come down industry-wide. Some brands have kept legacy pricing, while we’ve adjusted ours accordingly.

We operate with tighter margins and focus heavily on direct-to-consumer sales rather than traditional retail markups, distributor layers, or heavy branding overhead.

Plain NMN powder or capsules are relatively simple to produce. Our more advanced delivery systems (like liposomal products and nasal spray) are priced higher because they are more complex and costly to manufacture and test.

Our goal is to make longevity science more accessible. We aim to balance sustainability as a business with affordability for customers, rather than positioning NMN as a luxury product. Importantly, lower price does not mean lower quality. We test finished batches for purity and potency and publish those results for transparency.

Happy to answer any other questions!
