Two Rhodiola-based salidroside analysis research have been revealed in 2023 — one displaying a hormetic impact with a big stimulatory zone[1] and one other demonstrating unbelievable intestine well being results![2]
In dietary supplementation, putting the appropriate stability might be tough. We don’t need hormones like cortisol or estrogen to be too excessive, however we additionally don’t need them to be too low. As a way to maintain them within the applicable physiological vary, bloodwork is often required to information supplementation.
Two new research on salidroside in Rhodiola have been revealed in 2023: Improved intestine well being and hormesis for longevity and neuroprotection
There’s one class of dietary supplements the place that is much less relevant – adaptogens. Adaptogens assist normalize physiological processes, i.e. elevating cortisol when it’s too low or decreasing cortisol when it’s too excessive.
In additional technical phrases, an adaptogen ought to promote homeostasis by means of the regulation of physiological processes.
RhodioPrime 6X: Powered by 6% Salidroside
Certainly one of our favourite adaptogens is Rhodiola. The foundation has been proven to advertise cortisol homeostasis;[3,4] and struggle weight problems by inhibiting adipogenesis[5] whereas bettering glucose tolerance and insulin sensitivity[6] and suppressing urge for food.[7,8]
These are only a few of the advantages related to Rhodiola supplementation. There are others that may be particularly attributed to salidrosides, considered one of Rhodiola’s bioactive constituents.
The advantages of salidrosides
Analysis exhibits that salidrosides can:
So, with the lion’s share of Rhodiola advantages coming from salidrosides, we should always need a high-salidroside Rhodiola extract.
That’s the place RhodioPrime 6X from NNB Vitamin enters the image. In 2019, we observed vital shortcomings within the salidroside content material in commercially-available Rhodiola extracts. We approached NNB Vitamin to provide a higher-salidroside model, and inside 6 months, they introduced us with RhodioPrime 6X — at a whopping 6% salidroside content material, excess of the standard 0-1%!
New analysis on this portion of Rhodiola exhibits that this was an incredible concept:[19,
New Salidroside Research in 2023!
We published a detailed analysis of RhodioPrime 6X that’s linked above, and it’s well worth reading, but today we’re focusing on two new Rhodiola research studies that specifically target salidroside:
-
Rhodiola and Hormesis
The first study is a research review concerning rhodiola’s ability to stimulate hormesis, particularly with respect to longevity and neuroprotection.[1] It was revealed by Edward Calabrese and his staff of consultants in toxicology, danger evaluation, dose response, and hormesis on the College of Massachusetts. That is noteworthy as a result of he principally wrote the e-book on hormesis, and is cited quite a few instances in our explanations beneath.
What’s hormesis?
Hormetic compounds present advantages till the dose will get too excessive, and customarily their curve appears one thing like this.[21]
In hormesis, small doses of a compound are useful whereas bigger doses are poisonous.[22] Extra typically, your cells profit from an adaptive response to low-grade stress. This stress might be not simply chemical, but in addition physiological.[23] Train is definitely an instance of hormesis – the train itself is irritating, and even damaging, however due to the adaptive response triggered by train, your cells and muscle tissue can rebuild themselves to be even stronger than earlier than.
This sample is named a biphasic response[22] – i.e., dosing as much as a sure level yields a profit (the primary section), whereas exceeding that dose causes hurt (the second section).
Salidroside has a basic biphasic response
Past train, low-dose phytochemicals can even have hormetic results. In keeping with Edward Calabrese’s analysis evaluate slated to be revealed within the August 2023 version of Chemico-Organic Interactions, Rhodiola has hormetic properties with a basic biphasic response in a number of domains:[1]
From an earlier examine: Rhodiola markedly boosts temper scores[16]
- Growing older / Longevity
- Oxidative free radical stress
- Erythropoiesis (purple blood cell manufacturing)
- Neuroprotection
- Safety towards listening to harm
- Safety towards bone fractures
- Cartilage well being
- Bone cell proliferation
Whereas there are completely different mechanisms of motion behind these results, one massive takeaway from this examine is that animal research with massively excessive doses of salidroside displaying “poisonous” results aren’t essentially a nasty factor – subtoxic dosing of a chemical stressor is strictly what yields the hormetic profit.[1,24-27]
Typically, in hormetic conditions, there’s usually a most stimulatory response that results in results typically from 30% and 60% better than placebo controls. This vary additionally usually averages doses 10-20 fold beneath the toxicological/pharmacological threshold.[21]
From an earlier nootropic examine. Inclined to creating errors? Rhodiola appears to assist appropriate that.[18]
Nevertheless, there’s a whole lot of variability within the “stimulatory zone” throughout completely different herbs – not any two supplemental elements are the identical.
Salidroside has a very giant stimulatory zone
Fortunately, in quite a few research cited by this paper,[20,28-34] there have been no unfavourable results till large doses of salidroside have been administered — an incredible majority of dose ranges have been therapeutic.[1] And in different experiments, the very best dosing wasn’t deleterious — the outcomes from the very best doses merely returned to baseline, displaying the identical results as controls (after decrease/hormetic doses had advantages).[20,35-38]
RhodioPrime 6X from NNB Vitamin is a trusted supply, and excessive in salidroside!
Which means there’s a very giant stimulatory zone for Rhodiola, and with the doses typically really helpful — 200-600 milligrams per day in people — we’re unconcerned with overstepping the hormetic zone.
That is very useful for complement lovers and {industry} professionals: it represents a enormous step ahead in exactly quantifying the hormetic dose-response vary of Rhodiola extracts like RhodioPrime 6X.[1] Clearly, we don’t wish to take an excessive amount of of a hormetic complement, so we should know precisely the place the purpose of diminishing returns lies.
And in the end, Rhodiola’s toxicology is just not a priority for any cheap doses, in response to a 2019 evaluate of a number of toxicity research.[39]

Salidrosides’ Anti-Obesogenic Impact
The opposite examine we wish to point out right now is a salidroside-specific animal examine.[2] The researchers randomly assigned mice to considered one of three teams:
- Normal chow (CHOW)
- Normal chow + 15 mg/kg salidroside (CHOW+SAL)
- Excessive fats food plan + 15 mg/kg salidroside (HFD+SAL)
New analysis is displaying that rhodiola extracts excessive in salidroside are those with essentially the most potential… so why accomplish that many dietary supplements have such horrible standardizations? With RhodioPrime 6X, that each one modified…
The mice have been handled on this vogue for 8 weeks.
Predictably, the high-fat food plan worsened the metabolic well being of the mice, inflicting glycemic dysregulation and insulin resistance. However amazingly, the HFD+SAL group confirmed roughly the identical metabolic well being standing as CHOW and CHOW+SAL.[2] In different phrases, the examine authors demonstrated that salidroside remedy just about reversed the unfavourable metabolic results of the high-fat food plan!
Improved lipids and inflammatory biomarkers
Comparable results have been noticed for tumor necrosis issue alpha (TNF-a), serum lipopolysaccharide (LPS), and inflammatory interleukins.[2] And with respect to all cardiometabolic variables measured on this examine, salidroside remedy introduced HFD-fed mice in step with, or shut to in step with, standard-chow-fed mice.[2]
One notably vital and notable discount was in blood triglyceride (TG) ranges. From the visible knowledge supplied, we estimate that salidroside remedy lowered blood TG ranges by about 80%![2]
Summing up the outcomes, they discovered that SAL remedy in HFD-fed mice:[2]
- Decreased weight achieve and fats accumulation
- Improved signs of metabolic syndrome
- Diminished liver irritation
- Repaired intestinal harm
- Improved intestine flora
To this point, this was a reasonably normal randomized managed animal examine, however then, the researchers took issues to the following degree.
Can salidroside-enhanced intestine enhance fecal transplants?
In a second experiment, at week 4, the researchers transplanted feces from the dietary mice teams into a brand new group of recipient mice. The rationale for that is that gastrointestinal microflora is now a longtime think about metabolic well being, and fecal transplants work by establishing new microflora. Thus, if fecal transplants from salidroside-treated animals trigger metabolic enhancements, that may be taken as proof that salidroside’s results are a minimum of partly mediated by its affect on intestine microflora composition.[2]
The recipient mice have been randomly assigned to 3 teams, similar to the mice in experiment 1 – they received both CHOW, CHOW+SAL, or CHOW+HFD for 8 weeks after the fecal transplant.
Because it seems, the fecal transplants did trigger an a variety of benefits within the HFD-fed recipient animals. Extra particularly, they:[2]
- Decreased weight achieve and fats accumulation
- Repaired intestinal harm
So salidroside supplementation does seem to have a useful affect on the intestine microbiome.
Conclusion: Salidroside is the place one of the best Rhodiola advantages are
With improved intestine well being and hormesis for longevity/neuroprotection, we surprise if we’ll see extra Rhodiola in intestine well being dietary supplements
As soon as once more, we see the advantages of high-salidroside Rhodiola. Previous to 2020, it was too troublesome to discover a trusted and standardized extract that will stay available on the market lengthy sufficient for complement manufacturers to comfortably formulate with. NNB Vitamin solved that downside with RhodioPrime 6X, whose industry-leading 6% salidroside standardization will reliably be right here for years to return.
The hormesis examine is a superb growth for the complement {industry} – seeing researchers take steps towards exact quantification of optimum dose ranges for any complement is one thing we’ll at all times approve of.
And, to our information, fecal transplant research with salidroside haven’t been carried out earlier than the mouse examine we mentioned above, however we’re a bit much less concerned with that half, and extra concerned with the truth that it improved intestine well being so very a lot.
You’ll be able to learn extra about salidroside in our RhodioPrime 6X article, and browse extra concerning the herb typically in our Rhodiola article.
