Pantethine (B5)
Description
Pantethine is the biologically active form of pantothenic acid (B5) and a direct precursor to coenzyme A, which is central to fat and carbohydrate metabolism. It has well-documented effects on lipid profiles, particularly in lowering LDL and triglycerides while raising HDL, making it a natural option for cardiovascular support. Pantethine also nourishes the adrenal glands, which rely heavily on B5 during periods of stress. This activated form is more bioavailable than standard pantothenic acid supplements.
Effects
First weeks
no felt change
Weeks 4–8
lipid markers begin shifting on labs
Ongoing
adrenal and cholesterol support
How it Feels
This is a lab-driven supplement, not a felt one. Its value is in cholesterol numbers over a couple of months. Do not expect any noticeable day-to-day effect.
Usage
Commonly Referenced Starting Amount
300 mg/day
Commonly Referenced Amount
600–900 mg/day is the range used in lipid-management trials
Referenced Upper Limit
No upper limit has been established for pantethine or pantothenic acid
Onset
4–8 weeks (lipids)
Combinations
Pairs well with
Synergistic
CoQ10 — both support mitochondrial energy production via the CoA pathway
Omega-3 — complementary lipid-lowering via different mechanisms
Vitamin C — C supports adrenal CoA-dependent hormone synthesis alongside B5
Avoid combining
Contraindicated

Biomarkers to Track
Subjective
(Daily)
Energy levels mid-day (1–10)
Stress and adrenal fatigue score
Skin oiliness or acne changes
Objective
(Quarterly)
LDL and total cholesterol
Triglycerides (fasting)
HDL cholesterol level
Very safe with only mild digestive upset at most.
Few people need to avoid it.
Expecting to feel something, and quitting before the two months it takes to move lipid numbers.
Moderate (some human RCTs)
Lipid-lowering effect is modest compared with pharmaceutical options; evidence base is smaller than for niacin-family compounds generally.
