  The supplement stack now has one hub: keep maintenance D3/K2 and modest fish oil; use probiotics,
  B12/B-complex, magnesium, zinc, psyllium, or iron only when they answer a logged symptom/lab branch.
  Psyllium is the cleanest fiber add-on when stool regularity or fiber consistency is a target, but
  consistently good stool firmness makes it low-priority; do not add it just to chase bloating or pain.

# Supplement Stack + Add-ons

## Bottom line

The practical stack should shrink, not grow. Supplements are allowed only when they answer a specific branch: vitamin D sufficiency, modest omega-3 maintenance, logged probiotic symptom response, B12/homocysteine, magnesium/zinc deficiency-style support, tolerated fiber titration, or iron repletion after the stool-blood/iron branch justifies it. With stool firmness already consistently good, psyllium is optional/low-priority and should not be added just to treat bloating or pain. Do not add several items at once; the logs become unreadable.

Current medication/supplement safety details live in [Medication List + Hard Avoids](#sec-medication-avoid-list); antiplatelet/aspirin tradeoffs live in [Antithrombotic Strategy](#sec-antithrombotic).

## Keep / conditional / defer / stop

| Bucket | Items | Current call |
|---|---|---|
| Keep | D3/K2 maintenance; modest fish oil | No escalation. D is sufficient; K2 is not a proven valve/CAC treatment; standard-dose omega-3 has no clear bleeding signal, but high-dose purified EPA belongs to clinician-led plans. |
| Conditional | One multi-strain probiotic; S. boulardii; CBM588 | Use only as symptom tools. Multi-strain data are broader but low-certainty; S. boulardii mainly earns its place for diarrhea-type benefit; CBM588 is a targeted SUDD/butyrate trial if exact strain sourcing is confirmed. |
| Conditional | B12 or active B-complex | Best fit if the B12/homocysteine branch remains active; not a generic energy supplement. See the B12 owner for repletion vs maintenance dosing. Avoid chronic high-dose B6 because neuropathy is the critical toxicity signal. |
| Conditional | Magnesium | Consider only for a named target such as constipation tendency, sleep/muscle symptoms, or measured low-normal magnesium; avoid dose creep if stools loosen. Practical range: 200-300 mg elemental/day, preferably glycinate/citrate/malate rather than oxide. |
| Conditional | Zinc | Skin/epithelial-repair trial only if diet/intake or skin activity justifies it. Practical range: 15-25 mg elemental/day; add 1-2 mg copper if used long term. |
| Conditional / lower priority when stool is already good | Psyllium | Clean fiber add-on when stool regularity or travel-related fiber consistency is the target; real LDL/non-HDL/ApoB lowering is a secondary bonus. If stool firmness is already consistently good, do not start it just for bloating or pain. |
| Defer | Oral iron | Follow the ferritin/stool-blood branch; do not use iron to obscure an unresolved source-of-loss question. Keep iron away from fiber/tea/coffee/calcium when it is used. |
| Stop / avoid | Turmeric+piperine, broad anti-inflammatory botanicals, indefinite multi-probiotic stacking | Turmeric+piperine has vague upside and avoidable liver/interaction noise; probiotic stacking becomes commercial clutter unless logs show benefit. Quercetin is low-priority clutter unless deliberately testing a skin-focused add-on. |

## Psyllium: useful, but treat it like a trial

Psyllium husk is a viscous gel-forming soluble fiber from Plantago ovata. It is more practical than chasing many "gut health" supplements, but its main role is stool/fiber regularity. With consistently good stool firmness, it becomes a low-priority optional trial rather than a current bloating/pain tool. It has three relevant signals:

| Target | Evidence / meaning | Translation for this profile |
|---|---|---|
| Diverticular history | AGA guidance supports a fiber-rich diet or fiber supplementation after diverticulitis; broader diverticular cohorts favor higher fiber patterns. | Reasonable long-term hygiene when not in an acute unstable flare. It does not explain or treat positive stool blood; that branch stays separate. |
| Lipids / ApoB | Psyllium meta-analysis of 28 RCTs, median ~10.2 g/day, reduced LDL-C by ~0.33 mmol/L, non-HDL-C by ~0.39 mmol/L, and ApoB by ~0.05 g/L. FDA labeling rules recognize 7 g/day soluble fiber from psyllium husk as part of a low saturated-fat/cholesterol diet that may reduce CHD risk. | Useful incremental ApoB/LDL hygiene, not a substitute for atorvastatin, BP control, smoking abstinence, or imaging-guided prevention. ApoB is already fairly low, so the upside is modest but clean. |
| Stool regularity | AGA/ACG constipation guidance conditionally supports fiber supplementation; among evaluated fiber supplements, psyllium is the one with the clearest efficacy signal. Hydration is part of the recommendation; flatulence/bloating are common limits. | Main reason to use it. If stool firmness is already consistently good, the expected symptom upside is small and the risk is adding gas/distension/noise. |

## Psyllium trial protocol

- Decision gate: if stool firmness is already consistently good, skip psyllium during active bloating/coffee/meal-spacing experiments unless the specific goal is LDL/ApoB hygiene or travel-fiber backup.
- Product: plain psyllium husk powder/capsules, not stimulant-laxative blends or sugar-heavy mixes.
- Start: ~2-3 g/day for 3-4 days, then 5 g/day if tolerated.
- Target trial range: 5 g/day first; only move toward 7-10 g/day if stool/bloating logs improve and gas/distension do not rise.
- Administration: mix each dose with at least 240 mL water and drink promptly; add extra water during the day. Never take dry powder.
- Timing: separate from prescription medicines and key supplements by about 2-3 hours; be stricter around iron, thyroid meds if ever used, digoxin/salicylates/nitrofurantoin, and minerals.
- Iron-aware rule: if oral iron becomes active, keep psyllium away from the iron dose just like tea/coffee/calcium separation.
- Stop / do not start during: acute severe abdominal pain, vomiting, suspected obstruction, difficulty swallowing, unexplained worsening pain, or a new visible bleeding episode. Rectal bleeding is a clinician branch, not a fiber-fix branch.
- Success criterion: better stool regularity or easier high-fiber consistency without worse post-prandial bloating, abdominal circumference, or stool-photo pattern.

## Simplest self-test sequence

1. Stop turmeric+piperine and avoid adding new botanicals during the clean experiment.
2. If stable, trial stopping daily S. boulardii for 2-4 weeks while keeping the base multi-strain product unchanged.
3. Keep fish oil and D3/K2 steady; do not escalate either to chase Lp(a), valve, CAC, or generic inflammation effects.
4. Do not start psyllium just to chase bloating/pain while stool firmness is consistently good; keep it as a later low-dose trial only if fiber consistency, travel backup, or LDL/ApoB hygiene becomes the explicit target.
5. Add B12/B-complex, magnesium, zinc, or iron only when the relevant owner topic says the trigger is present.

# Omega-3 Supplementation

## Bottom line

Current fish-oil dosing is reasonable as maintenance. This audit found no concrete indication to escalate omega-3 for vague inflammation, Lp(a), or gut reasons. Hypertriglyceridemia, documented plaque with a cardiology plan, or another specific indication would be a different branch.

## What the evidence says

- 1-2 g/day EPA+DHA is a common trial range, but that does not automatically mean it is needed here.
- Higher-dose arterial-inflammation studies in elevated Lp(a) used much larger doses and more selected populations than routine supplement use (PMID: 37598001).
- 2024 meta-analysis of 11 RCTs found no overall bleeding increase with omega-3; the signal was concentrated in very-high-dose purified EPA (PMID: 38742535).

## Practical interpretation

- current ~600 mg/day EPA+DHA is acceptable maintenance
- escalation toward 1.5-2 g/day is optional and currently low-yield
- avoid self-directed 3-4 g/day strategies in a prior diverticular-bleed profile unless a specialist gives a specific reason

## Fish oil vs krill oil

- Per gram of EPA+DHA, krill oil does not clearly outperform standard fish oil (PMID: 37413768, 32073633).
- Source matters less than total EPA+DHA delivered and whether the product is tolerated.

## Key Takeaways for This Profile

1. Current dosing is a reasonable maintenance choice.
2. The evidence for routine escalation is weaker than the evidence for staying at a modest dose.
3. Bleeding risk at standard supplemental doses appears low despite the prior diverticular bleed.
4. High-dose EPA strategies should stay in the specialist / prescription bucket, not the self-directed supplement bucket.
