The Three Highs Supplement Guide: 4 Ingredients With Real Evidence – and 5 You Can Skip
If you have high blood pressure, blood sugar, or cholesterol, chances are your supplement cabinet is full – spirulina, propolis, reishi spore powder, various “blood pressure teas” – and your numbers still aren’t where they should be.
The problem? Most of these supplements have zero clinical evidence for managing three highs. This article separates what actually works from what’s a waste of money.
One Important Disclaimer First
Supplements are not medications. They cannot replace your prescribed blood pressure pills, diabetes medications, or statins.
Any product claiming “no need for medication, just take this supplement” is misleading you. Supplements are designed to support – alongside proper medication, diet, and exercise – by improving metabolic function and reducing fluctuations.
Keep this in mind as we look at which ingredients are worth choosing.
4 Evidence-Based Supplement Categories for Three Highs
Category 1: Deep-Sea Fish Oil (Omega-3 EPA/DHA)
What it does: Lowers triglycerides, improves blood vessel elasticity, provides mild anti-inflammatory effects
Numerous clinical studies confirm that 2-4 grams of EPA+DHA daily can reduce triglycerides by 15%-30%. For people with elevated blood lipids – especially high triglycerides – fish oil is one of the best-supported non-prescription options available.
How to choose: – Look at EPA+DHA content, not total “fish oil” weight. Each capsule should contain at least 500mg of active ingredients – Choose rTG form (re-esterified triglyceride) – absorption is approximately 70% higher than standard EE form – Look for third-party testing (IFOS certification) to ensure no heavy metal contamination
Who it’s for: Elevated triglycerides, mild hypertension, individuals with cardiovascular risk
Caution: If you take anticoagulants (such as warfarin), consult your doctor first – fish oil has mild blood-thinning properties
Category 2: Coenzyme Q10 (CoQ10)
What it does: Protects heart muscle cells, supports blood pressure reduction, relieves statin side effects
CoQ10 is a core cofactor for mitochondrial energy production, with the highest concentration in heart cells. Studies show that supplementing 100-200mg daily can reduce systolic blood pressure by approximately 11 mmHg on average.
This is especially important for people taking statin cholesterol medications – statins suppress the body’s natural CoQ10 production, causing muscle aches and fatigue. Supplementing CoQ10 can effectively relieve these side effects.
How to choose: – Choose ubiquinol form – absorption is 3-8 times higher than ordinary ubiquinone – Take with a meal containing fat for better absorption – 100-200mg daily, split into two doses
Who it’s for: Hypertension patients, people taking statins, older adults with reduced cardiac function
Category 3: Nattokinase
What it does: Dissolves micro-thrombi, improves blood flow, supports blood pressure reduction
Nattokinase is a proteolytic enzyme extracted from natto, a traditional Japanese fermented food. It has the ability to break down fibrin – the main structural component of blood clots. Multiple studies show that supplementing 2,000-4,000 FU (fibrinolytic units) daily can reduce systolic blood pressure by approximately 5-8 mmHg and improve blood viscosity.
How to choose: – Look at FU (fibrinolytic units), not milligrams. Effective dosage is 2,000+ FU daily – Choose pure nattokinase without added Vitamin K2 (K2 can counteract anticoagulant medications) – Take on an empty stomach or before bed for best results
Who it’s for: Thick or slow-flowing blood, mild hypertension, older adults with cardiovascular risk
Caution: If you take anticoagulants (warfarin, aspirin, clopidogrel), you must consult your doctor before use – there is an additive bleeding risk
Category 4: Soluble Dietary Fiber (Psyllium Husk)
What it does: Slows post-meal blood sugar rise, lowers LDL cholesterol, improves gut microbiome
Soluble fiber (such as psyllium husk, beta-glucan, and pectin) forms a gel in the digestive tract that slows carbohydrate absorption, effectively reducing post-meal blood sugar spikes. Soluble fiber also binds to bile acids, promoting cholesterol excretion and lowering LDL levels.
How to choose: – Psyllium husk is the most researched soluble fiber – 5-10g daily – Take 15-30 minutes before meals with a large glass of water – Start with a small dose and increase gradually to avoid bloating
Who it’s for: Elevated blood sugar, high LDL cholesterol, people with constipation
Which Supplements Are Basically Useless?
| Product | The Reality |
|---|---|
| Spirulina | A protein source, no evidence for lowering three highs |
| Propolis | Antioxidant properties, no direct evidence for blood pressure or blood sugar reduction |
| “Blood pressure teas” | Mostly placebo; some contain undisclosed pharmaceutical ingredients |
| Reishi spore powder | Immune modulation, no evidence-based support for three highs |
| Grape seed extract | Antioxidant, no significant clinical effect on three highs |
Quick Shopping Summary
- ? Worth buying: Deep-sea fish oil (rTG form), CoQ10 (ubiquinol form), nattokinase (2,000+ FU), psyllium husk fiber
- ? Be cautious about: Products claiming “fast blood pressure or blood sugar reduction,” formulas with undisclosed ingredient amounts
- ?? Always consult your doctor: If you take anticoagulants, blood pressure medication, or diabetes medication, inform your doctor before adding any supplement.
