Limu Original is a superfood juice shot that is a member of the Lium family of supplements whcih also include Limu Burn and the Limu Lean shake. All of the Limu supplements are said to be “superior liquid nutrition — all powered by a seaweed-based supernutrient called Fucoidan. “ In this review, I'll look at Limu Original juice and try to find research on it. I'll also look at what's said to be its main active ingredient too – fucoidan. Hopefully, what follows will give you a better idea if Limu is right for you.
What Is Limu?
Limu, also called Limu moui – is a brown seaweed or algae. The scientific name for brown algae is Phaeophyceae. According to a YouTube video I found, it's pronounced (FI-oh-fEE-she-I). Here is the Phaeophyceae Wikipedia page.
The specific type of brown algae mentioned on the bottle of Limu is called Sphaerotrichia Divaricata. All Limu supplements contain this is the type of brown seaweed.
Like all plants there are thousands of individual ingredients, although when it comes to Limu, one ingredient – called Fucoidan – is often highlighted as its main active ingredient. Fucoidan is pounced “FU-coy-din.”
According to the bottle I found on [easyazon_link identifier=”B00CMFU89E” locale=”US” tag=”mscscs-20″]Amazon[/easyazon_link], 1 oz (30 ml) of Limu Original has 33 servings and the following nutrition information:
|Amount Per Serving||Percent Daily Value|
|Total Carbohydrate||< 2g||< 1 % DV|
|Sugars||< 2 g||N/A|
|Proprietary Limu Blend||25 ml||N/A|
In the table above, N/A = no daily value has been established.
The label states that the Limu blend comes from the whole plant (Sphaerotrichia divaricata). This is wise
because it's probable the whole plant has more nutrients than just a single portion (extract) of the plant.
The label also states that Limu Original also contains these other ingredients in a “Proprietary All Natural Flavor Blend”
- Organic papaya puree
- Organic mango puree
- Pear juice concentrate
- Apple juice concentrate
The product also contains sodium benzoate, malic acid and potassium sorbate for freshness. The product also contains xanthian gum.
Several websites I saw discussing this product said “Go to pubmed and enter “Fucoidan” to see the research. Pubmed is the National Library of Medicine and is a repository of millions of studies from around the world. It's where I most usually go to when I research supplements.
While there is research on fucoidan, which I'll cover below, I was curious if Limu – the supplement– had any published clinical studies.
So, I went to Pubmed.gov entered “Limu.”
While I did see studies that mentioned Limu – the seaweed – I didn't see any studies on Limu Original, the dietary supplement.
- I then did a Google search for “Limu supplement pubmed.” I saw no clinical studies on the Limu supplement itself.
- I then searched ClinalTrials.gov to see if there were any ongoing studies on the supplement. At the time this review was written, I did not see any.
- I also checked the product website – TheLimuCompany.com – and likewise did not see any studies listed there either.
Therefore, I'm forced to conclude that at this time Limu – the supplement – appears to have no published clinical studies.
But what about Fucoidan, said to be the power behind Lium? It does have research, some of which I'll summarize below. But, first, lets briefly discuss what fucoidan is.
What Is Fucoidan?
Fucoidan is a type of carbohydrate found in brown algae (also referred to as brown seaweed. It's sometimes also called a sea vegetable). Fucoidan is said to have a poor absorption (about 2% or s0 if rat studies are to be taken as an indication?). That may not do away with any health benefits of fucoidan because -as can be seen below – there are some human studies showing something is going on when people ingest this compound.
As is pointed out in this 2015 review article – Therapies From Fucoidan: An Update – there are many types of fucoidan that come from different species of brown algae. Limu gets its fucoidan from Sphaerotrichia divaricata also sometimes called Tongan Limu Moui.
As for how much fucoidan is in Limu, I cannot say. The company states that it is not possible to know the exact amount as it would vary because the whole plant is used in making this supplement. In the review below, I will try to highlight how much fucoidan has been used in research.
Another ingredient in brown algae is fucoxanthin (fU-co-zan-thin). This is a carotonoid (plant nutrient). Some may have heard of beta carotene. It is also a member of the carotinoid family of nutrients. There are several hundreds of carotinoid molecules. Fucoxanthin is just one of them.
When I called the Limu company and asked about fucoxathin the person I spoke with couldn't give me any information about whether or not it was in the Limu drink. I also didn't see it mentioned on the product website either. As such I won't discuss fucoxathin here.
There are MANY studies on fucoidan. There are so many that it would be impossible to list them all here. Most of the studies I saw involved lab animals or were test tube studies. In the brief review of fucoidan below, I'll will try to highlight research that involves humans, because that's what everybody reading this is.
Fucoidan does have clinical studies on it in a variety of areas. If you want to see them, this page of Pubmed.gov should get you started. This list can be daunting to sift though, so to make it easier, I'll divide the research into different categorizes to help make your research easier.
I will also try to focus on human studies if possible. What follows is not an exhaustive review of fucoidan. I'm quite sure there will be studies I missed. My hope is that this will get you started if you decide to do your own research. If readers come across any human studies I missed, please let me know so I can update this review.
Fucoidan And Arthritis
In a 2015 study titled Effects of fucoidan from Fucus vesiculosus in reducing symptoms of osteoarthritis: a randomized placebo-controlled trial. Researchers noted that 300 mg of a fucoidan extract helped pain levels in 96 people with mild to moderate osteoarthrits of the knee and hip. In theory, less pain might mean more mobility. The fucoidan used in this study did not come from limu but a different type of brown seaweed, called Fucus vesiculosus, also known as bladder wrack.
Fucoidan And Cancer
In a 2007 study titled Fucoidan ingestion increases the expression of CXCR4 on human CD34+ cells, 3 grams (3000 mg) of fucoidan (taken from Tasmanian Undaria pinnatifida) given for 12 days was shown to improve immunity in people with a type of leukemia.
A 2011 study titlted Fucoidan reduces the toxicities of chemotherapy for patients with unresectable advanced or recurrent colorectal cancer, noted that fucoidan improved fatigue in people who were going through chemo therapy for colon cancer. In this study, people were given 150 ml/day of a liquid that contained 4.05 grams of fucoidan for 6 months. The fucoidan in this study was derived from a type of seaweed called Cladosiphon okamuranus
Test tube studies have also noted that fucoidan may have anti-estrogen properties. This might make it effective at some types of human cancers.
Fucoidan And Heart Disease
In a study titled Effect of fucoidan administration on insulin secretion and insulin resistance in overweight or obese adults, fucoidan 25 overweight adults randomly received either a placebo or 500 mg of fucoidan for 3 months. Compared to the placebo, those getting fucoidan, showed reduced LDL (bad cholesterol), reduced diastolic blood pressure and and increase in insulin production.
Fucoidan And Immune System
A study titled Supplementation of elderly Japanese men and women with fucoidan from seaweed increases immune responses to seasonal influenza vaccination, noted that 300 mg a day of fucoidan produced a more rhobust immune response to the flu vaccination than those who received a placebo. The fucoidan in this study came from Undaria pinnatifida.
Fucoidan And Colitis
Animal studies suggest fucoidan can reduce inflammation associated with colitis.
Fucoidan And Autism
I am not aware of any studies showing fucoidan (or Limu) helps autism symptoms in people who have autism. At the time this review was written, the connection between Limu and improvement in autism does not appear to have been studied. I'll update this as I become aware of studies on this topic.
Limu And Alzeheimers
I'm not aware of any studies showing fucoidan (or Limu) improves symptoms of Alzheimers disease in humans who suffer form this disease. The same is true for other forms of dementia also. At the time this review was written, the connection between Limu and improvement in Alzeheimers /dementia does not appear to have been studied. I'll update this as I become aware of studies on this topic.
Fucoidan has been studied for a variety of issues. If there is a health condition related to fucoidan you were curious about, leave a comment below and I will try to find research on it.
Can You Just Buy Fucoidan?
Some of the studies finding benefits used fucoidan derived from different species of brown algae. For example, one study I saw used fucoidan from Undaria pinnatifida while another used fucoidan obtained from Cladosiphon okamuranus. These are different than the type found in Limu Original (Sphaerotrichia divaricata).
Because of this, is it possible that fucoidan might be more important than the species of brown algae it's obtained from? I do not know but for those who want to just purchase fucoidan alone, there are several [easyazon_link keywords=”fucoidan” locale=”US” tag=”mscscs-20″]fucoidan supplements on Amazon[/easyazon_link] and I'm sure local health food stores have them too. I have no knowledge about whcih brand might be best or whether it is superior to that obtained from the Limu Original supplement.
How Much Iodine Is In Limu?
On the product website, a pdf fact product sheet can be downloaded. That sheet states that each 1 oz serving of Limu Original has less than 30 micgrograms of iodine. This low levels is attributed to the Tongan limu used in the product.
Brown seaweed is has been in other supplements previously reviewed such as:
- Arbonne Essentials Shake (Click to read review)
- Vital Factors (Click to read review)
- SlimQuick (Click to read review)
See those reviews for additional information.
While Limu Original is not marketed to help people lose weight, I sometimes notice brown seaweed in weight loss products. My theory is that this is because the iodine in seaweed night help us make thyroid hormone, which regulates metabolism. More iodine might mean more thyroid hormone. This, in turn might mean higher metabolisms – and more calories burned.
Whether or not this really works or not I cannot say. I also don't know what impact the iodine in Limu would have on thyroid hormone, metabolism or weight loss.
Does Limu Have Any Sugars?
The product website states that Limu Original has less than 2 grams of naturally occurring sugar per 2 oz serving. It also has no added sugars and no artificial flavors or sweeteners or artificial colors. It also does not contain any high fructose corn syrup.
Is It Kosher?
Yes, Limu is Kosher, vegan and gluten free. Limu Original bottles contain no BPA ( Bisphenol-A) (BPA) or PET (polyethylene terephthalate).
How To Buy Limu?
Limu Original is usually obtained from a Limu distributor. If you don't know any and want to purchase it from the company, I recommend you call them at 407- 548-3800. I'm sure they will be happy to help anyone who wants to order their products.
[easyazon_link keywords=”Limu” locale=”US” tag=”mscscs-20″]Limu supplements are also on Amazon.[/easyazon_link]
Who Makes Limu?
The company is called The Limu Company LLC and their website is TheLimuCompany.com. The website was created in 2003 so it has been around a long time. That's good.
The Better Business Bureau gave the Limu Company a rating of “A+” when this review was created. See the BBB file for updates and more information.
According to their Whois.com file and BBB file, The Limu Company is located at 610 Crescent Executive Ct Ste 110, Lake Mary, FL 32746-2111. If you search for the address (without the “Ste 110”) you see two large office buildings. My guess is the company is located in suite (“ste”) or office # 110 of that address.
According to the Better Business Bureau, the company contact number is 407- 548-3800. Their contact fax number is 407 804-5488. The LinkedIn page for the company states that it is privately owned and has between 51-200 employees (not including Limu distributors).
Another company website is LimuNation.com. This site appears to be for Limu Distributors rather than the general public interested only in ordering the product.
Limu Side Effects
I believe Limu Original is safe in healthy people. That said, here are a few things worth mentioning for those who take this – or other supplements.
Speak to your doctor first if you are pregnant/breastfeeding, have any health issues or take any medications. Stop taking Limu at least 2 weeks before having surgery. Because fucoidan may have blood thinning effects, people who take blood thinner medications should to speak to their doctor before using Limu.
Does Limu Work?
While Limu – the supplement – may lack published, peer reviewed trials, fucoidan (touted to be one of its main active ingredients) has been clinically studied. The bulk of those investigations appear to involve lab animals or are test-tube studies. The few human studies I was able to locate do appear to show fucoidan may be having some effects, although, given the small number of studies, I feel more research is needed to know for sure. I personally would like to see clinical trials on Limu -the supplement- and more human studies on fucoidan. Because Limu Original is derived from the whole plant, if it does work, I think its effects might be more complicated than any single nutrient, including fucoidan.
