Renew Sleep Supplement Review: Does This “Salt Water Trick” Really Work?

When I first heard about Renew Sleep Supplement and its “salt water trick” marketing angle, I was skeptical. After years of testing sleep aids and metabolism boosters, I’ve learned to look beyond the hype. I decided to give Renew a thorough trial to see if it could deliver on its promises of better sleep and enhanced metabolism.

What Is Renew Sleep Supplement?

Renew positions itself as a dual-action supplement targeting both sleep quality and metabolism. The formula contains eight key ingredients that work together to promote deeper sleep while supposedly optimizing your body’s fat-burning potential during rest. Unlike daytime fat burners that rely on stimulants, Renew takes the opposite approach – improve sleep first, and let your body’s natural processes handle the rest.

The Ingredients: How Effective Is This Formula?

Looking at the ingredient profile, Renew contains a mix of amino acids, adaptogens, and sleep-promoting compounds:

• L-Arginine (1200 mg): This amino acid boosts nitric oxide production, improving blood flow and potentially supporting growth hormone release during sleep. The 1200 mg dose is substantial and within the effective range.
• L-Lysine (1200 mg): Works synergistically with arginine for hormone balance and protein synthesis. Again, a solid dose that should be effective.
• L-Theanine (200 mg): One of my favorite sleep ingredients, this amino acid from green tea promotes relaxation without sedation. The 200 mg dose is spot-on.
• Ashwagandha Root Extract (150 mg): This adaptogen helps lower cortisol and stress levels. While effective, the 150 mg dose is on the lower end – I typically see benefits at 300-600 mg in other products I’ve tried.
• 5-HTP (100 mg): A precursor to serotonin that can improve mood and sleep quality. The 100 mg dose is appropriate.
• Melatonin (10 mg): This is a higher dose than many sleep supplements (which typically use 1-5 mg). From first-hand experience, this higher dose can be effective but might cause morning grogginess for some users.
• Magnesium (50 mg): Important for muscle relaxation and sleep, but at only 12% of the daily value, this dose is too low to have significant effects on its own.
• Zinc (15 mg): Supports immune function and testosterone production. This is a good dose at 136% of daily needs.

My Experience Taking Renew

I took Renew consistently for four weeks, taking the recommended four capsules about 45 minutes before bedtime. Here’s what I noticed:

Sleep Quality

The most immediate effect was on my sleep. Within the first few nights, I noticed I was falling asleep faster – typically within 15-20 minutes of laying down compared to my usual 30-45 minutes. My sleep tracker showed an increase in deep sleep time, averaging about 25-30 minutes more per night than my baseline.

However, I did experience some morning grogginess during the first week, likely due to the 10 mg of melatonin, which is on the higher end. This side effect diminished by the second week as my body adjusted.

Energy and Recovery

By the end of week two, I noticed I was waking up feeling more refreshed. My mid-afternoon energy slumps became less frequent, and my workout recovery seemed to improve. This makes sense given the formula’s support for growth hormone production via arginine and lysine.

Weight Management Effects

Regarding the metabolism and fat-burning claims, the results were more subtle. I didn’t notice dramatic weight loss, but I did lose about 1.5 pounds over the four weeks without changing my diet or exercise routine. More notably, I experienced fewer late-night cravings, which is likely due to better sleep regulation.

Comparing Renew to Similar Products

Having tried several sleep and metabolism formulas, I noticed Renew’s ingredient profile is strikingly similar to supplements like Resurge and Revive Daily. All three feature the amino acid combination of arginine and lysine paired with sleep-promoting ingredients.

What sets Renew apart is its slightly higher melatonin content (10 mg versus the 5-6 mg in many competitors) and the focused approach on just eight key ingredients rather than a kitchen-sink formula.

Compared to dedicated sleep supplements like ZMA formulas or pure melatonin products, Renew provides more comprehensive support for both sleep and recovery thanks to the adaptogenic and amino acid components.

Who Will Benefit Most from Renew?

From my experience, Renew works best for:

If you struggle with sleep onset (falling asleep) due to an overactive mind, the L-theanine and melatonin combination works particularly well. The ashwagandha and magnesium also help if stress is your primary sleep disruptor.

If you’ve noticed age-related metabolism slowdown, the growth hormone support from arginine and lysine might provide modest benefits, especially when combined with improved sleep quality.

If you tend to snack at night or make poor food choices when tired, the improved sleep regulation could help reduce those behaviors.

Who Should Avoid Renew?

I wouldn’t recommend Renew if:

You’re sensitive to melatonin – the 10 mg dose might cause excessive drowsiness or vivid dreams.

You’re taking medications for depression, anxiety, or blood pressure, as several ingredients might interact with these drugs.

You expect dramatic weight loss results without lifestyle changes. Renew might support your efforts, but it’s not a magic solution.

Value Assessment: Is It Worth the Price?

At approximately $49-69 per bottle (30-day supply), Renew sits in the mid-to-premium range for sleep and metabolism supplements. The multi-bottle discounts make it more economical for long-term use.

Looking at the ingredient quality and dosages, most components are well-dosed except for the somewhat underwhelming magnesium content. The arginine and lysine doses are generous compared to many competitors.

The 60-day money-back guarantee reduces the risk factor substantially, allowing you to try it without financial commitment.

The Bottom Line: My Overall Rating

After thorough testing and considering the formula, effects, and value proposition, I give Renew Sleep Supplement 3.7 out of 5 stars.

The formula delivers on its sleep-enhancement promises, with noticeable improvements in sleep quality and morning energy. The metabolism and weight management benefits are present but more subtle, which is realistic compared to the overhyped claims made by many supplements.

The high melatonin content is both a strength and potential drawback, depending on your sensitivity. The ashwagandha and magnesium doses could be more generous for optimal stress-reduction effects.

If better sleep is your primary goal with the added benefit of potential metabolic support, Renew is worth considering, especially with the money-back guarantee reducing your risk.
