Hypertension – Including 3-legged-stool model

This post is an update of an earlier post. It deals mainly with non-prescription items. Some prescription items can have adverse effects on the microbiome seen with other conditions. “No medical condition is an Island

After reviewing reviewed tested supplements, we use the Three-Legged-Stool model to get additional candidates and then check if there are studies supporting their use.

Prescription Responder and Non-Responders

I came across this 2021 article that was investigating DNA/SNP and hypertension drugs.

“Drug effectiveness was defined as 10% decrease in systolic blood pressure at 1 week follow-up. “

Genomic markers associated with successful treatment of hypertension with lisinopril: A pilot study [2021]

If you do not see that type of response, there may be genetics involved.

Base List

This base list comes from my 2019 review, “Hypertension – What we know” with most items coming from Nutrients and Nutraceuticals for the Management of High Normal Blood Pressure: An Evidence-Based Consensus Document. [2019] All of these are based on actual human clinical studies and not on rodent studies. See above for amount of impact for each substance. Current studies suggests that impact is linearly cummative.

Pycnogenol100–200 mg
Lycopene15–50 mg
Melatonin2–5 mg
Coenzyme Q10100–300 mg
Resveratrol>300 mg
Cocoa flavonoids200 mg
Calcium1500–2000 mg
Potassium4–5 gr
L-Arginine10-20 gr
Taurine1-2 gr
Quercetin150 mg [2009]

Additional items are discussed in Role of natural herbs in the treatment of hypertension, 2011, but with less critical review.

Candidate Modelled Substances

For modelling substances for a condition, I often use a three legged tool as shown below

Items were ranked by number of bacteria favorability impacted. The top 3 suggested modifiers are below. The next step is to see if there is any literature. [Good Impact: Bad Impact]

  • resistant starch [12:6]
    • Trial using it [2021]
    • 3.3 mm HG drop in DBP (no change in SBP) [2019]
  • berberine [12:10]
    • Studies suggests lowering [2021]
  • Slippery Elm ( Ulmus macrocarpa ) [11:4]
    • Lowers in Rodent studies [2008]

The next 4 items contains one surprise – licorice is usually associated with increase of BP

  • lactobacillus plantarum (probiotics) [9:7]
    • Reduced mean arterial pressure [2021]
    • Effect of Lactobacillus plantarum containing probiotics on blood pressure: A systematic review and meta-analysis [2020]
    • “A statistically significant reduction in systolic blood pressure was also observed”[2017]
  • glycyrrhizic acid (licorice) [9:8}
    • “Women taking licorice have experienced elevated blood pressure” [2021]
    • ” No electrolyte abnormality, significant changes in blood pressure or blood glucose levels were observed during the [Licorice] study.” [2019]
    • appear to cause hypertension in association with potassium chloride [2018]
  • rosmarinus officinalis (rosemary) [9:1]
    • “Both blood pressure variables of SBP and DBP reflect the clinically significant antihypotensive effect of Rosemary essential oil that was maintained throughout the treatment period. ” [2014]
  • fructo-oligosaccharides (prebiotic) [9:6]
    • Nothing

The next items

  • zinc [8:3]
    • “Angiotensin-converting enzyme (ACE) is a zinc-dependent dicarboxypeptidase ” [2021] – impacts prescription hypertension medicines
    • “Zinc and copper might be not independently associated with hypertension in US adults.” [2018]
  • saccharomyces boulardii (probiotics) [8:3]
    • nothing
  • wheat [8:1] – complex, ancient varieties appear to have benefits
    • “Antihypertensive and antioxidant activities of enzymatic wheat bran protein hydrolysates” [2020]
    • Short-Term Hemodynamic Effects of Modern Wheat Products Substitution in Diet with Ancient Wheat Products: A Cross-Over, Randomized Clinical Trial [2018] SBP decreased
  • arabinoxylan oligosaccharides (prebiotic) [8:1]
    • nothing
  • inulin (prebiotic) [8:2]
    • Inulin Supplementation Reduces Systolic Blood Pressure in Women with Breast Cancer Undergoing Neoadjuvant Chemotherapy [2019] SBP: -4 mm Hg
  • lactobacillus salivarius (probiotics) [7:1]
    • Nothing
  • vitamin a [7:2]
    • Inverse association between dietary vitamin A intake and new-onset hypertension[2021] “Our results emphasized the importance of maintaining relatively higher vitamin A intake levels for the prevention of hypertension.”
  • oregano (origanum vulgare, oil) |[7:2]
    • Nothing

We do see some items from our first list, with predictions tending to agree. Remember that we are doing a naïve count by bacteria and dealing with fuzzy data

  • quercetin [6:2]
  • resveratrol (grape seed/polyphenols/red wine) [6:5]
  • melatonin supplement [5:8]
  • magnesium [4:0]
  • Cacao [3:1]

Bottom Line

This illustrates the use of the three legged stool approach for treating conditions. The use of microbiome appears to produce an extended list of candidates substances that appears to be in general agreement with studies. Each candidate substance should be researched because we have a complex mixture of bacteria.
