Alpha-Lipoic Acid
Alpha lipoic acid supplement guide: 600 mg/day oral dosing, R-ALA vs racemic absorption, neuropathy trial data, antioxidant mechanism, interactions.
Lion's Mane
Lion's mane mushroom (Hericium erinaceus) supplement profile: hericenones and erinacines stimulate NGF in vitro. Human cognition trials are small.
Effects at a glance
Alpha-Lipoic Acid
- •Approved Rx for diabetic neuropathy in Germany at 600 mg/day IV (Thioctacid) since 1960s
- •Improves neuropathy symptoms (TSS, NIS) at 600 mg/day IV across ALADIN and SYDNEY trials
- •R-ALA enantiomer absorbs 40-100% better than racemic mixtures
- •Activates AMPK; produces small HbA1c reductions in T2DM
- •Plasma half-life ~30 minutes; split dosing or sustained-release is standard
- •Hypoglycemia risk with insulin or sulfonylureas; medication adjustment may be required
Lion's Mane
- •Edible medicinal mushroom containing NGF-stimulating hericenones and erinacines
- •Mori 2009 trial (n=30) in mild cognitive impairment showed cognitive improvement at 3 g/day for 16 weeks, reversing 4 weeks after discontinuation
- •Saitsu 2019 (n=31) in older adults reported MoCA improvements at 3.2 g/day over 12 weeks
- •Multiple small mood trials suggest reduced anxiety and depression scores at 1 to 4 g/day extract
- •Mechanistic case rests on NGF stimulation and remyelination support; in vivo human NGF measurement is absent
- •Product quality varies substantially; mycelium-on-grain products can be over 50% grain by weight

| Molecular formula | C8H14O2S2 | mixed extract |
| Mechanism | Dual lipid- and water-soluble antioxidant; redox cycles with dihydrolipoic acid (DHLA) to scavenge ROS, regenerate vitamin E and C, and chelate transition metals. Activates AMPK in liver and muscle; cofactor for pyruvate and alpha-ketoglutarate dehydrogenase complexes. | Hericenones and erinacines stimulate NGF mRNA expression and NGF protein release in cultured neurons; secondary anti-inflammatory and remyelination-supportive activity in preclinical models. |

Safety profile
Alpha-Lipoic Acid
Common side effects
- nausea
- abdominal discomfort
- diarrhea
- sulfurous odor
- rash (rare)
Contraindications
- pregnancy and lactation (insufficient safety data)
- active insulin autoimmune syndrome predisposition
Interactions
- insulin and sulfonylureas: additive hypoglycemia; medication dose adjustment may be required(major)
- thyroid hormone: may reduce T4 to T3 conversion at high doses(moderate)
- biotin: ALA competes with biotin uptake; chronic use can induce biotin insufficiency(minor)
- iron supplements: ALA chelates iron and reduces absorption; separate dosing(moderate)
- chemotherapy (oxidative-stress-dependent agents): theoretical interference; coordinate with oncology team(moderate)
Lion's Mane
Common side effects
- mild GI upset
- occasional skin rash
- contact dermatitis (rare)
Contraindications
- mushroom allergy
Interactions
- anticoagulants: theoretical antiplatelet effect, no documented clinical events(minor)
Which Should You Take?
Alpha-Lipoic Acid and Lion's Mane score evenly on the criteria we weight (goal breadth, legal accessibility, evidence depth). The conditionals below should drive the decision more than any aggregate score.
- → If your priority is metabolic health and glucose control, pick Alpha-Lipoic Acid.
- → If your priority is healthspan extension, pick Alpha-Lipoic Acid.
- → If your priority is focus or working memory, pick Lion's Mane.
- → If your priority is nerve health, pick Lion's Mane.
Edge case: Half-lives differ materially (Alpha-Lipoic Acid ~0.5 hr vs Lion's Mane ~6 hr). Lion's Mane reaches steady state faster; Alpha-Lipoic Acid is easier to dial in if tolerability is uncertain.
Default choice: either is defensible. Alpha-Lipoic Acid edges out on goal breadth + legal accessibility; Lion's Mane is the right call if your priority sits in the goals listed above.
