Dietary Supplements & Blue Blockers

Bacillus coagulans

Bacillus coagulans (GREAT10015). Take 1 capsule daily with any meal. Bacillus coagulans is a probiotic bacterial strain that may play an important role in managing chronic colds and sinus problems by supporting the gut microbiome and, in turn, the immune system. Because a significant portion of the immune system is closely connected to gut health, Bacillus coagulans helps maintain a healthy, balanced intestinal microbiome. This may reduce the overgrowth of harmful microorganisms that can otherwise contribute to inflammation and infections. This strain produces bioactive compounds with anti-inflammatory properties and supports the intestinal barrier, potentially reducing the risk of increased intestinal permeability, often referred to as “leaky gut,” which can trigger chronic systemic inflammation and weaken the body’s defenses against respiratory and sinus infections. By helping stabilize the gut microbiome, Bacillus coagulans may support immune regulation and reduce the frequency of recurring infections, including colds and sinusitis. It may also help relieve bloating and digestive discomfort associated with imbalances in the gut microbiome, ultimately supporting overall health and resilience. Contains authentic LactoSpore® Bacillus coagulans.

Here’s what customers say about Bacillus coagulans

I sometimes struggle with a stress-sensitive stomach and have been looking for a more sustainable solution for a long time. I’ve tried many different types of probiotics, prebiotics and postbiotics. I’ve now been using Bacillus Coagulans LactoSpore® for a month together with Saccharomyces Boulardii Plus+ and your L-Glutamine, and I can already feel a difference compared with before. My stomach doesn’t feel as stressed, and I’m not as aware of it in the way I used to be. Bacillus Coagulans feels like the missing link. So pleased! – Marie

My veterinarian recommended giving my dog the probiotic Bacillus Coagulans because of skin issues and itching. He is also a researcher at KI. He also mentioned that he had recommended this to a good friend who got much better. Since I myself have psoriasis and an unbalanced stomach, I tried it myself and got better. – Eva

Sleep Plus+

Sleep Plus+ (GREAT10057). Take 4 capsules daily, 30–60 minutes before bedtime. Sleep Plus+ is the best and most important sleep supplement you can take. It is a specialized formula containing carefully selected amino acids, minerals, and vitamin B6 to support the body’s natural sleep processes and the pathways involved in producing melatonin naturally. It promotes relaxation, helps you fall asleep, and supports better sleep quality without leaving you feeling groggy or experiencing a “hangover” the following morning. Unlike basic sleep supplements, Sleep Plus+ stands out for its exceptional purity and carefully selected premium ingredients. From a biological perspective, Sleep Plus+ works by supporting the nervous system’s ability to wind down and the body’s natural circadian rhythm signaling. Glycine, taurine, and L-theanine help promote a calmer nervous system, while magnesium bisglycinate supports muscle relaxation and normal nervous system function. L-tryptophan serves as a building block for the body’s natural production of serotonin and melatonin. Zinc and active vitamin B6 contribute to normal neurotransmitter metabolism and hormonal balance, both of which are important for overnight recovery.

Here’s what customers say about Sleep Plus+

I’ve been taking Sleep Plus+ for three months now, and together with glycine, it’s worked really well for my sleep problems caused by menopause symptoms and long-term stress. I’m now sleeping through the night and getting more deep sleep than before. Highly recommend! – Veronica
Posted on 10/8/26

At times, I find it really difficult to fall asleep. Sleep Plus+ genuinely helps! Maybe not on the first or second night, but after that I fall asleep quickly and without feeling anxious or restless. Once I’m asleep, I sleep well for the rest of the night, and I’m so grateful to have found this supplement! – Kia

Magnesium M4

Magnesium M4 (GREAT10003). Take 2 capsules daily with breakfast. Magnesium is an essential cofactor in more than 300 enzymatic processes, including nerve signaling, energy production, and the regulation of muscle tone. Maintaining adequate magnesium levels throughout the day may help reduce neuromuscular hyperactivity, muscle tension, and stress-related symptoms that could otherwise interfere with falling asleep later in the evening. Magnesium citrate and magnesium malate are organic forms of magnesium with high bioavailability that are generally gentle on the digestive system. Malate is also involved in mitochondrial energy metabolism, which may help reduce physical fatigue that can sometimes negatively affect sleep quality. Magnesium bisglycinate supports deeper relaxation and may help improve sleep onset. If you choose not to take magnesium glycinate, which we advise against, you should instead take 3 capsules of Magnesium M4.

Here’s what customers say about Magnesium M4

“Please, please make sure you never run out of your magnesium! You can really tell the difference compared with other brands!” — Marie

“I’ve tried several other high-quality magnesium supplements, and while they worked reasonably well, none came close to this one. It’s truly in a league of its own! Waking up around 4 a.m. and not being able to fall back asleep may finally be a thing of the past. Such a relief!” — Agneta

Vitamin D3 with K2

Vitamin D3 with K2 (GREAT10022). The recommendation is to obtain 70–80 IU of vitamin D per kilogram of body weight each day from all sources combined, including sunlight, food, and supplements. On average, women obtain approximately 170 IU of vitamin D per day through their diet, men approximately 205 IU, and children ages 2–19 approximately 195 IU. The remaining vitamin D requirement needs to be met through supplementation unless you expose approximately 80% of your body to sunlight without sunscreen between roughly 11 a.m. and 3 p.m. for at least 20 minutes when the UV index is 3 or higher.

How to calculate your intake: Calculate your weekly vitamin D requirement and adjust your intake accordingly. For example, if your weekly requirement is 30,000 IU, take 5,000 IU daily from Monday through Saturday and skip Sunday. Take vitamin D with a meal containing fat. Vitamin D plays a central role in immune system function and is particularly important for people experiencing recurring or chronic colds and sinus problems. The active form of vitamin D, calcitriol, regulates gene expression involved in the body’s defenses against infection by stimulating the production of antimicrobial peptides, including cathelicidin (LL-37).

These peptides have demonstrated direct activity against bacteria and viruses in the respiratory tract, potentially helping reduce the risk of infections and inflammation in the sinuses. Vitamin D is a fat-soluble prehormone that is converted into its active form in the liver and kidneys. This active form binds to the vitamin D receptor (VDR), influencing both calcium regulation and immune responses. Vitamin D deficiency can impair immune function and increase susceptibility to respiratory infections, which is frequently observed in people experiencing chronic colds and sinusitis. In regions with limited sunlight exposure, particularly during the winter months, the risk of vitamin D deficiency is greater and may contribute to an increased incidence of upper respiratory infections. Vitamin D supplementation is therefore often recommended to help maintain adequate levels, support the body’s ability to fight infections, and reduce inflammation associated with chronic colds and sinus problems.

Here’s what customers say about Vitamin D3 2000 IU + K2 MK7

After blood tests showed low vitamin D levels, I have now been taking your Vitamin D3 2000 IU with vitamin K for over a year, and the results are the best I have ever achieved with a vitamin D supplement. I used to feel incredibly tired, but now I have more energy than ever and my immune system feels stronger than ever. I have hardly been ill at all since I started taking this product. – Julia

I’ve had some issues with every other vitamin D3 supplement I’ve tried in the past (around ten different brands), but I’ve had no problems whatsoever with this one, so I’ll definitely keep taking it. I take this together with your magnesium to help minimise low mood and lack of energy, and it works really well for me. – Christian

NRC for NAD+

NRC for NAD+ (GREAT10012). Take 1 capsule daily with breakfast. NRC for NAD+ is a unique supplement that increases NAD+ levels. NAD+ is an essential coenzyme that plays a central role in cellular energy metabolism and repair processes. It is crucial for maintaining high and consistent energy levels. Recurring infections, chronic colds, and sinus problems often expose the body to oxidative stress and mitochondrial dysfunction, potentially weakening the immune system and prolonging recovery. By increasing NAD+ levels, cellular energy production may improve, particularly in the rapidly responding cells of the immune system, helping strengthen the body’s resistance to infections. Adequate intake of NRC for NAD+ may help reduce fatigue, improve recovery, and support cellular repair following inflammation. In addition, NAD+ directly influences inflammatory signaling pathways such as NF-κB, potentially reducing the persistent low-grade inflammation that often aggravates sinus problems and respiratory infections. NRC for NAD+ also supports DNA repair and cellular stability, making it particularly valuable during chronic infections. By supporting immune function at the mitochondrial level, NRC for NAD+ may contribute to increased energy, improved recovery, and a more balanced immune response. These are important factors when dealing with recurring colds and sinusitis.

Here’s what customers say about NRC for NAD+

“Since I started taking NRC for NAD+ from Greatlife, I’ve noticed that my energy levels stay consistent throughout the day. I look healthier and more refreshed, and I receive lots of compliments. I also feel sharper and more focused, both at work and during exercise. My recovery after a demanding day is noticeably faster, too. The capsules are easy to take. In short, NRC for NAD+ has been a real game changer, and I absolutely recommend it!” — Natascha

I’ve been taking NRC for NAD+ for about 30 days now, and I have to say I noticed a difference in my energy levels after just 14 days. I lead a very active lifestyle, so the difference has been quite noticeable. I also take other supplements from you that I feel do me good, but the only thing I’ve changed recently is adding NRC for NAD+. That’s why I’m convinced it’s what’s made the difference to my energy levels. It’s given me that extra little boost of energy! A huge thank you to everyone who develops these fantastic supplements! – Tony

Oyster Pure

Oyster Pure (GREAT10006). Take 4 capsules daily with any meal. Do not take this supplement if you have hyperthyroidism (an overactive thyroid). This is one of my most important supplements. Oysters have existed on Earth for approximately 500 million years and may be one of nature’s greatest superfoods. Oysters are best known as an aphrodisiac, meaning a substance believed to stimulate sexual desire. However, oysters are also exceptionally rich in vitamin B12, zinc, copper, selenium, and iodine. They also contain all the amino acids, along with compounds such as riboflavin, niacin, betaine, beta-alanine, taurine, and carnitine.

Customer reviews:

“I’m currently recovering from an extremely severe chronic illness. I’ve tried more supplements than I can count, and oyster extract is by far the best. It has had an enormous impact on my healing process since I introduced it into my protocol several months ago.” — Matt

“Within a few weeks of starting oyster extract, I noticed firmer, smoother, more radiant skin and less hair shedding. Oyster extract is also an absolute must for anyone following a detox protocol.” — AK

“I’ve been struggling with constant colds and a stinging, burning sensation throughout my body for the past several months. My energy levels have been extremely low for a long time. After just a few days of taking Oyster Pure, I no longer feel sick! I still have a runny nose, but the burning sensation is gone, and I feel much more energetic overall. This is huge for me because I’ve been suffering and feeling desperate!” — Linn

Wild Alaskan Sockeye Salmon Omega-3

Wild Alaskan Sockeye Salmon Omega-3 (GREAT10007). Take 3 capsules daily with any meal. Omega-3 fatty acids are essential fats that the body cannot produce on its own and must therefore obtain through the diet. These fatty acids, particularly EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which are found in our omega-3 supplement, play important roles in maintaining brain function, cardiovascular health, and reducing inflammation throughout the body. Omega-3 fatty acids have also been shown to benefit vision, support healthy skin, and contribute to reducing the risk of certain diseases.

Here’s what customers say about Wild Alaskan Sockeye Salmon Omega-3

“I’ve been searching for a high-quality omega-3 supplement for a long time because I don’t get enough through my diet. I’m really happy with this one and will definitely order it again!” — Emelie

“Alaska Omega-3 has helped improve my skin. It’s better hydrated and looks much fresher! I also like that Alaska Omega-3 naturally contains vitamin D.” — Ayad

“Alaska Omega-3 is both high-quality and pure. I feel more energetic when I take it.” — Åsa

“My son and I have been using Alaska Omega-3 for quite some time, and we both feel noticeably more energetic. I’m very particular about supplement quality, and Alaska Omega-3 is the best I’ve found on the market.” — Christina

Electrolytes Plus+

Electrolytes Plus+ (GREAT10011). Mix 1 stick pack daily into a large glass of water. Can be mixed with Creatine Monohydrate Creavitalis® and Collagen Peptides Type I & III VERISOL®. Electrolytes Plus+ does not taste good. Electrolytes such as sodium chloride (NaCl), magnesium, and potassium are essential for maintaining proper hydration, supporting nerve signaling, and enabling normal muscle function. Sodium and potassium work together to regulate blood pressure and fluid balance within cells, while magnesium supports muscle relaxation and nervous system function. Together, these electrolytes help the body function optimally and are important for preventing dehydration, muscle cramps, and fatigue.

Here’s what customers say about Electrolytes Plus+

I’ve tried just about every electrolyte supplement on the market, as I travel a lot for work and jet lag is practically an everyday occurrence for me. They might not be the best-tasting electrolytes out there, as they’re unflavoured, but they’re by far the most effective. I highly recommend Greatlife Electrolytes+. – Martin

In my opinion, these are the best no-nonsense electrolytes on the market. No sugar, no artificial sweeteners and no vitamin C. They work really well for intense training, but also during water fasting. The only downside is that they are only available in single-serving sachets, which makes each dose a little expensive. A tub option would have been nice. But the product itself is excellent. – Janne

I’ve been looking for a clean electrolyte mix for a long time and have so far used XXX [I removed the other brand], but even their unflavored version contains OptiMSM (methylsulfonylmethane) and vitamin C, which I don’t want to consume. This is the only one I’ve found that consists of pure electrolytes in the right form for good absorption. It tastes salty and good, with just a slightly strange aftertaste from the magnesium bisglycinate, but it doesn’t bother me and is only a sign of its purity. The single-serve packets are convenient to bring along. – Kevin

Creatine Monohydrate Creavitalis®

Creatine Monohydrate Creavitalis® (GREAT10009). Take 2 heaping teaspoons daily in a large glass of water, preferably immediately after exercise. Can be mixed with Electrolytes Plus+ and Collagen Peptides Type I & III VERISOL®. Creatine enhances physical performance during successive bursts of short-term, high-intensity exercise. Daily creatine consumption may enhance the effects of resistance training on muscle strength in adults over the age of 55. Creatine is one of the most extensively studied substances in the world, with more than 66,000 published studies indexed in PubMed. More recent research has demonstrated that creatine may benefit not only muscle function but also brain health. Creatine may improve cognitive performance by increasing energy availability in brain cells, particularly during mentally demanding tasks. Studies have suggested that creatine supplementation may help improve short-term memory, mental clarity, and recovery following periods of mental exhaustion. Creatine has also demonstrated neuroprotective properties by reducing oxidative stress and inflammation. Creavitalis® is a premium form of creatine monohydrate manufactured in Europe under exceptionally strict purity and quality standards. It is tested for heavy metals, microbiological contamination, and solubility. Compared with less expensive creatine products, Creavitalis® offers better bioavailability, dissolves more easily in liquids, and is gentle on the stomach. It also remains stable over time, helping ensure that the creatine does not break down into inactive creatinine before use.

Here’s what customers say about Creatine Monohydrate Creavitalis®

I’ve been practising martial arts for over 20 years and have long combined my training with strongman training. I’ve been using Greatlife’s creatine for several years now, both for its physical and cognitive benefits. Six years ago, I suffered several very serious herniated discs, and it’s taken me nearly four years to work my way back. Creatine has been an important part of that journey. I’ve noticed a significant difference in my strength, energy and recovery, and above all in how my body responds to the demands I place on it. But for me, it’s actually the cognitive effects that matter most. After many years of martial arts and repeated blows to the head, I’ve struggled particularly with my short-term memory. That’s where creatine has made an enormous difference for me. I’d even go so far as to say that the cognitive benefits I’ve experienced have been at least as noticeable as the physical ones. It’s now a supplement I wouldn’t want to be without. Thank you, Greatlife, for a genuinely excellent product! – Isaac

Starting to take your creatine was absolutely the best thing I’ve ever done. I was off work with burnout and had no energy for anything. Quite quickly, I started to feel more energetic and found it easier to manage everyday activities than before. I’ll definitely keep taking it. – Agneta

I bought your creatine about a month ago and it works really well. I play tennis and beach volleyball quite often, and I’m happy to say the supplement significantly shortens my recovery time. Really good. I’m about to order more and also try your omega 3. – Bostjan

Collagen Peptides Type I & III VERISOL®

Collagen Peptides Type I & III VERISOL® (GREAT10074). Mix 1 stick pack daily into a large glass of water. Can be mixed with Creatine Monohydrate Creavitalis® and Electrolytes Plus+. Collagen is the most abundant protein in the human body and a fundamental structural component of the skin, fascia, tendons, ligaments, cartilage, bones, and other connective tissues. It provides tensile strength, structural integrity, and resilience, helping tissues withstand mechanical stress while maintaining their normal function. As we age, collagen production gradually declines, while existing collagen fibres undergo structural changes that can affect skin elasticity, connective tissue quality, and tissue recovery. Research suggests that supplementation with specific bioactive collagen peptides may improve skin elasticity, hydration, and wrinkle appearance. Clinical studies on VERISOL® have demonstrated improvements in several measures of skin quality, including elasticity and wrinkle depth, following regular supplementation. Research has also suggested potential benefits for brittle nails. Unlike ordinary collagen powders, VERISOL® contains a standardised profile of specific bioactive collagen peptides developed for the skin. These peptides are broken down during digestion into amino acids and smaller peptide fragments, some of which can be absorbed intact and may influence the activity of fibroblasts, the cells responsible for producing collagen and other components of the extracellular matrix. Greatlife’s Collagen Peptides Type I & III VERISOL® provides 5,000 mg of clinically studied VERISOL® peptides, combined with 1,000 mg of pharmaceutical-grade glycine and 200 mg of PureWay-C® vitamin C. Glycine is particularly important because approximately every third amino acid in collagen is glycine, making it essential to the collagen triple-helix structure. Vitamin C acts as a critical cofactor for the enzymes responsible for hydroxylating proline and lysine, processes necessary for the formation and stability of collagen fibres. PureWay-C® combines vitamin C with citrus bioflavonoids and lipid metabolites. The formula is free from added sugar, artificial sweeteners, unnecessary fillers, and magnesium stearate, and is manufactured in an ISO 22000-certified facility according to strict quality and hygiene standards.

Organ Mix

Organ Mix. Take 6 capsules daily with a meal. Organmix contains liver, heart, and kidney from organically raised, grass-fed cattle. It is a healthy supplement because organ meats are exceptionally nutrient-dense. Compared with muscle meat alone, organ meats provide a broader spectrum of micronutrients, making them an excellent complement rather than your primary protein source every day. Muscle meat is often rich in methionine, while collagen-rich tissues provide greater amounts of glycine and proline. For this reason, a nose-to-tail approach to eating may promote a more balanced amino acid intake.

Blue Blockers Optic Pro

Blue Blockers Optic Pro are glasses designed to block 99.43% of blue light emitted by smartphones, tablets, televisions, computer monitors, and even ordinary household lighting. These are among the best specialized blue-light-blocking lenses we have encountered. The frame and lenses weigh just 30 grams in total, and the lenses are shatter-resistant. The frame rests comfortably on the nose, and the temples do not irritate the ears. Blue Blockers Optic Pro can significantly improve your ability to fall asleep and the quality of your sleep throughout the night. Research has shown significant improvements in sleep efficiency and sleep latency (the time it takes to fall asleep) among people wearing blue-light-blocking glasses.

Here’s what customers say about Blue Blockers Optic Pro

“I have to say, I sleep so much better with these glasses. I no longer need to take melatonin capsules, which also used to give me nightmares. I put the glasses on three hours before bedtime and sleep incredibly well. I have Asperger’s syndrome and naturally lack melatonin. My brother has been using similar glasses for a long time, and he doesn’t have the condition, so he only needs to wear them for about an hour. For anyone with Asperger’s or autism, I really recommend these glasses. They work, and they’re cheaper than medication. The quality is excellent, they’re comfortable, and they fit everyone. Definitely the best purchase I’ve made this year!” — Dennis

These glasses are truly worth the money! I was on strong sleeping pills for two years, and my doctor prescribed even stronger ones when the old ones stopped working. Eventually, I got tired of taking medication and decided to try something completely different – these glasses. At first, I didn’t notice much of a change, but after just a week, my sleep started improving. Today, it’s been three years since I quit medication, and I only use these glasses! They are absolutely magical! If you put them on a few hours before bedtime, you’ll sleep like a dream! I’ve recommended them to everyone I know who struggles with sleep, and they’re all thrilled! – Nderim ademi

“They simply make me feel sleepy. The biggest difference is that when I wear them, my eyes no longer feel itchy or gritty the way they sometimes do after using my phone or tablet too much in the evening. What a difference! Thank you!” — Patrik
