Life Extension Magnesium Threonate Stress Review

If you feel like your mind isn’t as sharp as you’d like, Life Extension Magnesium Threonate may be your best bet. This supplement is ideal for anyone hoping for a quick brain boost with long-lasting effects. 

With a focus on healthy memory and youthful cognitive function, Magnesium Threonate can help you get your mind back on track.

Almost everyone has experienced the struggle of trying to focus when all you want to do is relax. Brain fog isn’t easy to fight, but sometimes it can feel like there’s so much in your brain that you feel like it’s overflowing. 

Magnesium is vital for brain function, and unfortunately, your brain starts losing magnesium as you age. Because you don’t get much magnesium from your diet and environment, supplements like these can give you the extra help that you’re missing. 

Life Extension Magnesium Threonate comes in bottles of 90 vegetarian capsules, meant to last you for 30 days. The brand offers either a one-time purchase or a subscription option for the following prices:

  • One-time purchase: $30
  • Subscription option: $27 (10% discount)

The brand website also offers you a 10% discount on your order by buying 4 bottles at once ($27 each).

You can find this supplement on the following retail partner websites for a one-time purchase:

  • Amazon: $28
  • Walmart: $33
  • iHerb: $30

Ingredients Label

The main ingredient of Life Extension Magnesium Threonate is magnesium. Magnesium[1] is essential for brain health, but it starts to deplete with age. 

Although mild magnesium deficits aren’t that noticeable, they can get to a much more serious level. This is reflected in the number of neurodegenerative brain diseases that people experience in their old age. 

Nutritional Value

Magnesium[2] is crucial in providing your brain with a boost, helping with many different cognitive functions like memory and learning. This is especially useful for people as they age because their natural magnesium levels start to drop. 

Magnesium can even help after the experience of traumatic brain injury[3], protecting against neurological deficits.


Life Extension Magnesium Threonate comes with three major benefits for everyone:

  1. Healthy brain function and youthful cognition
  2. Important synaptic connections maintained between brain cells
  3. Improved brain signaling between pathways

How Does It Work

When you take Life Extension Magnesium Threonate, the magnesium makes its way to your nervous system and brain. This ingredient boosts your natural properties and strengthens the connections to provide you with a long-term brain boost and improved health overall.

How to Take & Dosage 

You should take 3 capsules of Life Extension Magnesium Threonate a day unless a healthcare provider has recommended something different. You’ll see the best results if you take this supplement daily.

Life Extension Body Trim and Appetite Control Review

Losing weight isn’t a one-step process. It requires many different factors coming together to make the change happen. 

For most people, that can include eating well, exercising regularly, and avoiding all other temptations. But one thing people forget to add to their healthcare regimen is an excellent natural supplement. 

Now I’m not saying that taking a supplement can replace the hard work that comes with everything you need to do to lose weight. Still, consuming certain vitamins and minerals can make a difference that can make the process less of a struggle. 

With Life Extension Body Trim and Appetite Control, you get the chance to continue making healthy choices without feeling the temptations of all the yummy cravings around you. 

With its primary focus on reducing cravings and keeping you full after every meal, you may realize that your weight loss journey has taken on a much more efficient route. 

Life Extension Body Trim and Appetite comes in bottles of 30 vegetarian capsules, meant to last you for 30 days. The brand offers either a one-time purchase or a subscription option for the following prices:

  • One-time purchase: $23
  • Subscription option: $20 (11% discount)

The brand website also offers an 11% discount when you buy 4 bottles at once. Each supplement will then cost you $20

You can find this supplement at Walmart for $27 (one-time purchase).

Ingredients Label

Life Extension Body Trim and Appetite is made from an ingredient named Metabolaid, a unique compound made of lemon verbena extract and hibiscus.

Lemon verbena extract is derived from a plant, while hibiscus is a flower. Both ingredients have great digestive properties[4] and are useful in helping you control your appetite and curb unhealthy cravings.

Nutritional Value

There are many nutritional benefits of the ingredients in Life Extension Body Trim and Appetite, all of which work together to provide you with the best support for your digestion and  weight loss.

By keeping you full and sated after a regular meal, you’re not tempted to eat anything unhealthy, preventing you from overeating.


Life Extension Magnesium Threonate comes with the following benefits for those who use it:

  1. Reduced cravings and controlled appetite
  2. Up to 5% weight loss when combined with a healthy diet and exercise
  3. Free Body Trim app with a product that encourages a healthy lifestyle

How Does It Work

Life Extension Body Trim and Appetite works by helping to control your appetite. A huge portion of weight gain is knowing when to stop eating, even when you’re full.

So, the main ingredient in this supplement provides you with a signal so that you don’t stuff yourself with food that you can’t handle. 

It’s important that you pair this supplement with a healthy diet and exercise, so you can see the best results of this supplement. The supplement alone may not help you see the results you’d like without a healthy lifestyle.

That’s why this supplement comes with a free app for you to track your progress and receive encouragement on your hard work.

How to Take & Dosage 

You should take 1 capsule of this supplement a day before breakfast. You’ll notice the best results if you take the supplement daily. 

Life Extension NAD+ Cell Regenerator and Resveratrol Review

When you’re so busy with life, it can get easy to get down in the dumps. No one thinks about using dietary supplements to get their energy back, but believe it or not, there are natural ingredients out there that can charge your metaphorical batteries and get you back to your peppy self.

Life Extension NAD+ Cell Regenerator and Resveratrol is an energy-boosting supplement that can jump-start your day at a cellular level. With the goal of longevity, this supplement aims to boost your cellular energy, improve your cellular metabolism, and encourage healthy aging. 

Life Extension NAD+ Cell Regenerator and Resveratrol comes in bottles of 30 vegetarian capsules, meant to last you for 30 days. The brand offers either a one-time purchase or a subscription option for the following prices:

  • One-time purchase: $45
  • Subscription option: $40 (11% discount)

The brand website also offers a discount of 11% for a 4-pack ($40 each).

You can find this supplement on the following retail partner websites (one-time purchase):

  • Walmart: $56
  • iHerb: $18

Ingredients Label

The serving size for this supplement is one capsule, and it contains the following ingredients:

  • Niagen (nicotinamide riboside chloride): 300mg
  • Bio-quercetin phytosome: 15mg
  • Trans-resveratrol: 100mg
  • Red grape and wild blueberry: 40mg
  • Fisetin: 10mg

Non-active ingredients include silica, maltodextrin, microcrystalline cellulose, vegetable stearate, and vegetable cellulose to form the capsule itself.

Nutritional Value

This supplement has a few different ingredients. However, the two main ingredients are Niagen and resveratrol, which come together to provide you with cellular health and energy. 

Your body naturally produces vitamin B3, which works to repair your cells and make you look younger by releasing the essential enzyme NAD+[5]. That’s exactly what Niagen[6] does as well. 

Both Niagen and vitamin B3 are alternatives to each other, so this supplement contains an ingredient that may slow down aging.

Resveratrol[7] generally promotes and maintains health and longevity, ensuring that you live a long and healthy life. More specifically, this ingredient can have an impact on diseases and keep you safe throughout old age. 

Other properties of resveratrol[8] include antioxidative, anti-inflammatory, and anticancer properties.

All ingredients within this supplement work together to increase NAD+ levels in your body, which has enormous benefits for middle-aged and older adults[9]


Life Extension NAD+ Cell Regenerator and Resveratrol can provide you with the following benefits:

  1. Fighting fatigue at the cellular level
  2. Reversing specific aging genes to make you look and feel younger
  3. Providing mitochondrial health and youthful cellular energy
  4. Reducing oxidative stress 
  5. Promoting cardiovascular health

How Does It Work

The two main ingredients of Niagen and resveratrol work together to heal your cells and keep you healthy and young in the long-term.

Niagen increases NAD+ levels in your system to increase cellular energy, while resveratrol[10] works by managing and even preventing diseases, conditions, and aiding recovery from injuries.

How to Take & Dosage 

You should take 1 capsule a day of Life Extension NAD+ Cell Regenerator and Resveratrol with or without food. You’ll see the best results if you take this supplement daily for a whole month. 

Who Is Life Extension For?

Life Extension Review

Based on this Life Extension review, many products by this brand cater to anyone over 18. This isn’t uncommon, as most supplements contain doses and ingredients that may not be suited for young children.

A product like the Magnesium Threonate would be a better fit for you if you’re looking to boost your brain function, whereas Body Trim and Appetite Control would be better for you if you’re struggling with losing weight and keeping it off. 

Meanwhile, a product like NAD+ Cell Regenerator and Resveratrol is more inclusive and almost anyone can benefit from using it, as it helps provide you with long-term cellular energy.

Please note that if you are pregnant, nursing, taking medication for any serious illnesses, have a weakened immune system, or have any severe allergies or reactions, you should speak with your doctor before taking Life Extension supplements.

Life Extension Side Effects

Life Extension Review

Because Life Extension supplements come from natural ingredients that mimic the body’s vitamins and minerals, there are no official side effects reported about any of the products.

However, as this brand works with dietary supplements, there is still a risk that you may experience stomach cramps, nausea, or poor bowel movements. This is especially likely if you don’t follow the suggested dosage.

Life Extension Reviews: What Do Customers Think?

Life Extension Review

This Life Extension review found quite a positive reaction to the products I went over. Customers rated the products highly with detailed success stories posted on the brand website, as well as partner websites like Amazon, Walmart, and iHerb.

The Life Extension products I reviewed posted the following ratings on the brand website:

  • Life Extension Magnesium Threonate: 4.7/5 stars by 422 reviewers
  • Life Extension Body Trim and Appetite: 3.1/5 stars by 35 reviewers
  • Life Extension NAD+ Cell Regenerator and Resveratrol: 4.8/5 stars by 263 reviewers

Life Extension targets a variety of different goals with their many products, including improved brain function, weight loss, and boosted energy. The customers who have tried their supplements mostly had great things to say about the benefits that they experienced.

One satisfied customer commented on the change he noticed after taking Magnesium Threonate for 2 months, stating, “I experienced an immediate shift in mental clarity on the first dose. Now after two months, I am excited about improved thought organization, increased multitasking ability, and increased short and long term memory.”

This was supported by another post on Amazon, where a customer made a comment along the same lines, saying: 

“Morning of Day 4 the brain fog is gone. After 3 years of the cloud living in my consciousness slowly putting me to sleep, I have taken initiative and made the effort to stop the numbing effects of whatever it is that is slowing me down and not caring.”

The Body Trim and Appetite supplement also has positive ratings. One customer commented, “After taking this supplement for about a week, I did notice a change in my tendency to snack. The evening is when I tend to snack, not because I’m hungry but because I have developed a really bad habit to do so. It’s really helping!” 

The few negative reviews about this supplement were regarding the lack of results, but since all bodies are different, it can take people an additional time to see results.

The brand also holds a 3.1/5-star rating on Trustpilot, with 60% of reviews ranking as “excellent.” Most customer complaints are about shipping times and customer service, though that does imply that very few people have problems with the products themselves.

All in all, most people who tried the Life Extension products were happy with their purchase, and some even mentioned using them for multiple years. The brand’s supplements have helped many people and have reached the goals they set out to! 

Is Life Extension Legit?

Life Extension Review

Based on my evaluation of the brand, its products, and the many reviews posted on multiple platforms, I think Life Extension is legit.

The brand has very clear details posted on their website and all third-party retailer sites regarding how each product works and what they are made of.

There are many customer reviews that have commented on the benefits they’ve experienced since starting to take Life Extension products which make their effectiveness believable. 

There are no complaints about Life Extension’s shipping policy, and it seems like everyone who placed an order got their products right on time. Plus, the brand has a transparent approach to deliveries, where they’ve outlined the different delivery times and prices on their website.

This Life Extension​​ review can say with confidence that this is a legitimate supplement brand that has done its research.

Is Life Extension Worth It?

Life Extension Review

This Life Extension review finds that this brand is worth purchasing for many different reasons. The variety of products, the effectiveness of the ingredients, and the glowing customer reviews are only the tip of the iceberg when you consider the positive features of this brand.

On the off chance that you buy a Life Extension supplement and discover that it’s not right for you, you have 12 whole months to contact the customer service team and either get a replacement product or a credit on your account. 

Overall, I believe that Life Extension is worth a try
