Ranked Solutions
Ranked by how much each one actually moves the needle — our SAC Efficacy Score™. Supplements, protocols and gear compete in ONE ranking.
Omega-3 (EPA/DHA)
Supplement25-35% triglyceride drop + cardiovascular-event reduction at 2-4 g/day
8.1/10SAC Efficacy Score™- Effect size45%Large
- Evidence40%Very strong
- Reliability15%Works for most
Why these numbers?
Effect size: 4 g/day of purified EPA cut major cardiovascular events by 25% in 8,179 statin-treated patients (Bhatt 2019), and an updated meta-analysis of 13 trials links marine omega-3 to fewer heart attacks and cardiovascular deaths (Hu 2019). The strongest supplement effect on this page — 7.0/10.
Evidence: A landmark RCT plus a 127,000-patient meta-analysis: 9.2/10.
Reliability: Dose-dependent; 2–4 g EPA/DHA is the range the trials used, not one capsule. 8.4/10.
Fewer events, not just better numbers.

Omega-3 (EPA/DHA) · 8.1Berberine
Supplement~20-25% LDL reduction + better glucose control (30+ RCTs)
7.4/10SAC Efficacy Score™- Effect size45%Moderate
- Evidence40%Strong
- Reliability15%Works for many
Why these numbers?
Effect size: Berberine lowered LDL by ~25 mg/dL and triglycerides by ~44 mg/dL across randomised trials (Dong 2013) and improves glucose control in type 2 diabetes (Lan 2015). 6.4/10.
Evidence: Two meta-analyses, mostly Chinese trials of moderate quality: 8.4/10.
Reliability: Consistent metabolic effects; drug interactions and GI upset limit who can run it. 7.8/10.
LDL and glucose down, in the trials.

Berberine · 7.4Magnesium Glycinate
Supplementmodest blood-pressure reduction + rhythm support
- Effect size45%Moderate
- Evidence40%Strong
- Reliability15%Works for many
Why these numbers?
Effect size: Magnesium supplementation lowered blood pressure by about 2 mmHg systolic and 1.8 diastolic across 34 double-blind trials (Zhang 2016), more in the deficient. Modest, real — 5.8/10.
Evidence: A large meta-analysis: 8.2/10.
Reliability: Most adults run low; glycinate is the tolerable form. 7.2/10.
Two points quieter, more if you're low.

Magnesium Glycinate · 7.0Krill Oil (EPA/DHA)
SupplementEPA/DHA lower triglycerides + support cardiovascular health; phospholipid form aids tolerance
⚑ EPA+DHA per serving is often lower than a dosed fish oil — read the actives6.9/10SAC Efficacy Score™- Effect size45%Moderate
- Evidence40%Strong
- Reliability15%Works for many
Why these numbers?
Effect size: Krill oil delivers EPA/DHA in phospholipid form and matched fish oil's metabolic effects at a lower EPA+DHA dose (Ulven 2011); an early trial showed lower LDL and triglycerides (Bunea 2004). The omega-3 effect, gentler on the stomach — 5.6/10.
Evidence: Small trials; the case borrows from the omega-3 literature: 8.2/10.
Reliability: Well tolerated, less fishy; the dose per capsule is low, so read the milligrams. 7.0/10.
Omega-3 that sits well.

Why these numbers?
Effect size: Inorganic nitrate and beetroot juice lowered systolic blood pressure by about 4.4 mmHg across 16 trials (Siervo 2013) — a real, food-based effect on the number that predicts the most. 5.6/10.
Evidence: A systematic review and meta-analysis of randomised trials: 8.0/10.
Reliability: Consistent in adults with normal-to-high pressure; antibacterial mouthwash blocks the pathway. 6.2/10.

Why these numbers?
Effect size: Algal DHA lowered triglycerides by ~15% and raised HDL in a meta-analysis of 11 trials — with a small LDL rise to watch (Bernstein 2012). The vegan route to the omega-3 effect — 5.5/10.
Evidence: Meta-analysis of randomised trials: 8.2/10.

Why these numbers?
Effect size: Aged garlic extract lowered systolic pressure by ~9–12 mmHg in uncontrolled hypertensives (Ried 2013) and by ~10 mmHg with better arterial stiffness in a 2020 trial (Ried 2020) — comparable to a first-line drug in responders. 5.0/10.
Evidence: Several randomised trials from one group plus meta-analyses: 7.6/10.
Reliability: Hypertensives respond; normotensives see little. Kyolic-type aged extract is the studied form. 6.8/10.

⚑ clearest benefit in statin users6.1/10SAC Efficacy Score™- Effect size45%Modest
- Evidence40%Moderate

Why these numbers?
Effect size: CoQ10 eased statin-associated muscle symptoms in a 12-trial meta-analysis (Qu 2018) and lowered systolic pressure by up to 17 mmHg in hypertensive trials of variable quality (Rosenfeldt 2007). Clearest for statin users — 5.2/10.
Evidence: A solid statin meta-analysis, a weaker blood-pressure one: 7.4/10.
Reliability: Statin users and the over-40s respond; ubiquinol form, with fat. 5.6/10.

- SAC News2026 — Red Yeast Rice Is a Statin: 28 Brands, a 120-Fold Dose Gap, and No Label · Monacolin K, the active compound in red yeast rice, is chemically identical to the prescription statin lovastatin — the EU says so in a binding regulation. Researchers bought 28 brands at mainstream US retailers: two contained none at all, and following each label's own daily serving the dose ranged more than 120-fold.
