About GDR Labs’ Heart Health Supplements
Heart disease is the number one killer worldwide. Many people take heart health supplements for blood flow and overall cardiovascular health.
GDR Labs offers four flagship supplements for targeting heart health, including:
- Carditrol: Natural heart health supplement
- Sirtuin: Natural antioxidant support
- Cholamax: Natural vitamin D fortification
- MAG-ION: Natural magnesium support
GDR Labs heart supplements support cardiovascular health using science-backed ingredients like beetroot, vitamin D3, and magnesium. These ingredients may help manage blood pressure, enhance circulation, reduce inflammation, and boost overall heart function.
Other GDR Labs heart health supplements, such as Sirtuin, function by utilizing antioxidants. Antioxidants neutralize the free radicals and reactive oxygen species that cause inflammation. Inflammation can worsen symptoms of heart disease and increase the risk of heart attack and stroke.
The remaining two heart health supplements in GDR Labs’ catalog are vitamin D and magnesium supplements. Vitamin D and magnesium are crucial for heart health, and deficiency in either nutrient could increase the risk of heart disease.
All GDR Labs heart health supplements are priced between $43 and $63 per bottle. Each bottle contains a one-month supply of liquid formula.
We’ll explore each of the GDR Lab’s heart health supplements in greater detail below.
Carditrol
Carditrol is GDR Labs’ best-known heart health supplement. Like the other three cardiovascular health supplements listed here, it is a concentrated liquid. To promote heart health, take 1 mL (about one full dropper) daily.
Carditrol supports heart health via:
- Supporting blood flow
- Promoting overall cardiovascular health
- Using beetroot extract and vitamin D3
Each 1mL (50 drops) serving of Carditrol contains three active ingredients in a 900mg proprietary blend. Those active ingredients include beetroot powder, black pepper extract, vitamin D (100% DV), and D-limonene:
Beetroot
Beetroot is one of the best-known ingredients in the world for heart health; some take beetroot daily. Beetroot contains nitrates. Your body uses nitrates to create nitrite, which converts into nitric oxide. Nitric oxide (NO) is known for widening blood vessels and supporting blood flow. Multiple studies have connected beetroot extract to better heart health, and some take it daily for blood pressure, cardiovascular health, and overall heart wellness. In a 2018 study, researchers found that beetroot juice supplements were cost-effective in reducing blood pressure by promoting nitric oxide production.
Black Pepper Extract
Black pepper extract contains a natural molecule called piperine linked to absorption. It helps your body absorb certain plants, herbs, and other nutrients. Your body may struggle to absorb plant extracts like beetroot without combining them with black pepper extract.
Vitamin D
Vitamin D is crucial for immune function, bone health, and blood flow. You could struggle maintaining good heart health if you’re not getting enough vitamin D through sunlight or dietary sources. A 2019 study, for example, found that people with vitamin D deficiency tended to have higher blood pressure and that taking a vitamin D3 supplement was linked to systolic and diastolic blood pressure drops.
D-Limonene
D-limonene is a natural oil in oranges, lemons, grapefruit, and other citrus fruits. It’s a monoterpene. Supplement companies typically add D-limonene to give formulas a pleasant scent and flavor.
Overall, GDR Labs designed Carditrol as a highly bioavailable heart health supplement linked to blood flow, cardiovascular wellness, and overall health. Based on testing on 15,000+ Americans, GDR Labs claims the supplement has a 90% success rate, with many people improving blood pressure and overall blood circulation with the liquid formula.
Sirtuin
Like most GDR Labs supplements, Sirtuin is available in Regular Strength or Clinical Strength varieties.
Sirtuin is positioned as an anti-aging, heart-supportive formula powered by resveratrol-rich Japanese knotweed. By targeting SIRT1 gene activation, Sirtuin may promote youthful energy, cellular longevity, and enhanced cardiovascular and brain function.
Most of the GDR Labs Sirtuin formula consists of antioxidants. GDR Labs claims to have added “one of the world’s most powerful antioxidant ingredients” to help achieve powerful effects.
Some of the benefits of GDR Labs’ Sirtuin include:
- Fight aging at the cellular level
- Powerful antioxidants
- Promote healthy brain and heart function
- Age-defying blend to stimulate the SIRT1 gene
Sirtuin works by stimulating the SIRT1 gene. Research has connected this specific gene to enhanced cellular function and youthfulness. By boosting the activity of this gene, Sirtuin could increase energy, cognition, strength, enthusiasm, and overall vitality.
Each 1mL serving of GDR Labs Sirtuin contains one primary active ingredient along with two complementary ingredients in a 900mg proprietary formula, including:
Japanese Knotweed 10:1 Extract
GDR Labs added Japanese knotweed to Sirtuin because it’s one of the most potent antioxidants in the world. Formally known as Polygonum cuspidatum, Japanese knotweed is known for being one of the best natural sources of resveratrol, the popular plant-based antioxidant. Resveratrol and Japanese knotweed are naturally present in grapes and other fruits. It’s a popular anti-aging compound that, when taken orally, could promote noticeable effects. One 2017 study, for example, found that taking 1,000mg of resveratrol from Japanese knotweed daily significantly increased circulating T cells and regulatory T cells, helping with inflammation and immune function.
Black Pepper Extract
GDR Labs added black pepper extract to Sirtuin for absorption. Studies suggest piperine, a natural black pepper molecule, enhances certain substances’ absorption. Without black pepper extract, your body struggles to absorb meaningful doses of some substances.
D-Limonene
Sirtuin contains the same D-limonene found in Carditrol and other heart health supplements. D-limonene is a natural oil from grapefruit and other citrus fruits. It helps the liquid Sirtuin formula taste better when held in your mouth.
GDR Labs recommends taking Sirtuin for at least 30 days to assess its benefits fully. However, some notice results within days of taking the supplement for the first time.
Sirtuin is priced at $63 to $89 per bottle (depending on whether you purchase the Regular Strength or Clinical Strength option).
Cholamax
Cholamax is an energy, immunity, and health supplement that promotes everything from heart health to immunity to strong bones.
GDR Labs designed Cholamax as a way to “achieve optimal health.” To do that, Cholamax targets different areas of human health, including:
- Elevate well-being and energy
- Support immune function
- Boost mood
- Enhance overall vitality
- Strengthen bones
- Fortify heart health, physical health, mental clarity, and more
If you want to perform at your best, Cholamax aims to help. Like other GDR Labs’ heart health supplements, Cholamax is a highly concentrated liquid formula. You can buy it in Regular Strength ($43 per bottle) or Clinical Strength ($69 per bottle) options, with the Clinical Strength version being twice as strong.
To achieve these effects, GDR Labs has added a single active ingredient to Cholamax: a strong dose of vitamin D (along with black pepper extract for absorption):
Vitamin D
Each 1mL (50 drops) serving of Cholamax contains 125mcg of vitamin D (625% DV) in the form of cholecalciferol. Studies show people deficient in vitamin D tend to have significantly worse heart health, brain health, immune function, and bone health than people who get their recommended daily intake of vitamin D. You can get vitamin D through sunlight exposure. Some take vitamin D3 supplements daily. It could be because of low vitamin D levels if you’ve felt mentally foggy, physically tired, or generally off lately.
Black Pepper Extract
GDR Labs added black pepper extract to Cholamax to promote absorption. Studies show that black pepper extract helps the body absorb vitamin D and other nutrients more efficiently.
Thanks to Cholamax, getting a potent daily dose of vitamin D is easy. Instead of swallowing large pills or standing in the sunlight for hours, you can swallow one full dropper of Cholamax.
MAG-ION
MAG-ION blends magnesium and essential minerals to promote heart and overall health.
MAG-ION is available in Regular Strength or Clinical Strength varieties. Like all other GDR Labs supplements, the formula is made in the United States and tested by third parties.
Some of the benefits of MAG-ION, according to GDR Labs, include:
- Support muscle and nerve function
- Enhance energy production
- Support overall health
- Promote better sleep
The benefits of MAG-ION are diverse because magnesium, the primary active ingredient, has varying influential roles throughout the body. The formula also contains 72 trace minerals to target other areas of health.
GDR Labs adds magnesium, sodium, and trace minerals to each drop of MAG-ION. Active ingredients include:
Magnesium
Magnesium is an essential mineral that influences hundreds of systems throughout the body – including your nervous system. It’s also crucial for muscle function. GDR Labs links magnesium to 600+ essential bodily functions, inkling health, sleep, heart health, and more. With MAG-ION, you get a strong dose of magnesium (420mg / 100% DV) to support all of these areas of health.
Sodium
Each serving of MAG-ION contains 7mg of sodium, less than 1% of your daily value. Typically, most adults get enough sodium through dietary sources. However, sodium deficiency could cause fluid imbalance, dehydration, muscle and nerve dysfunction, and other health issues. With MAG-ION, you get a small sodium dose to support your heart and overall health.
Natural Ionic Trace Minerals
The remaining ingredients in MAG-ION are ionic minerals found in small doses. They’re unnamed trace minerals that could promote health, wellness, immune function, and heart activity. You could have an increased risk of health problems if deficient in one or more minerals. Each drop of MAG-ION contains 72 trace minerals to promote overall health.
MAG-ION is made in the United States and lab-tested for purity and potency.
What Makes GDR Labs’ Heart Supplements Unique?
Many heart health supplements are available today – from beetroot powders to vitamin D3 capsules. Why pick GDR Labs’ heart supplements? What makes the company’s heart health supplements unique?
Here are some of how GDR Labs differentiates itself from competitors:
Easy-to-Take Liquid Formulas
All four heart health supplements listed above are easy-to-take liquid formulas. You place one full dropper in your mouth, hold it for 30 seconds, and then swallow. This is an easy way to take supplements without swallowing a capsule or using an injection.
Bioavailable Delivery System
The liquid delivery system enhances the absorption of all four heart health supplements listed above. For example, your body immediately absorbs some ingredients using the sensitive blood vessels around your mouth. GDR Labs also adds complementary ingredients specifically for absorption – like natural oils and black pepper extract, which can boost bioavailability.
Honest Advertised Effects
GDR Labs doesn’t claim its supplements can rapidly lower blood pressure or solve all your heart health problems overnight. Instead, the company makes honest claims about its supplements and their ability to promote heart health, support healthy blood pressure, and maintain overall wellness.
Regular & Clinical Strength Options Available
Most GDR Labs supplements, including all four heart health supplements, are available in Regular Strength or Clinical Strength varieties. Clinical Strength features double the dose of active ingredients at a slightly higher cost, helping you enjoy even more powerful effects.
Subscriptions & Multi-Bottle Discounts Available

For example, Most heart health supplements have just one to four active ingredients—including one or two main ingredients that account for 99% of the proprietary formula.
Small Batches for Freshness
GDR Labs produces supplements in small batches to ensure freshness. Instead of mass-producing thousands of bottles and leaving them on shelves for months, GDR Labs takes a different approach.
