Magnesium Glycinate vs Citrate
Glycinate for sleep & anxiety, citrate for constipation. Both well-absorbed, different uses.
Ubiquinol vs CoQ10
Ubiquinol absorbs 2-3x better, especially over 50. Standard CoQ10 fine for younger adults.
Ashwagandha vs Rhodiola
Ashwagandha calms; rhodiola energizes. Match the adaptogen to your dominant pattern.
NMN vs NR
Both raise NAD+ similarly. NR has clearer FDA status; NMN was reclassified in 2022.
Melatonin vs Magnesium for Sleep
Different sleep problems. Melatonin = circadian timing. Magnesium = nervous system calming.
Glucosamine vs Chondroitin
Mixed evidence for both. Glucosamine sulfate slightly stronger for moderate knee OA.
Whey vs Casein Protein
Whey post-workout (fast). Casein at bedtime (slow, sustained). Complementary, not competing.
Curcumin vs Meriva
Standard curcumin barely absorbs. Meriva phytosome delivers 29x absorption. Form matters.
Creatine Monohydrate vs HCL
Equivalent at matched doses. Monohydrate has 500+ studies and costs 2-3x less. HCL helps if you have GI issues.
Collagen vs Whey Protein
Different goals entirely. Whey wins for muscle. Collagen wins for skin and joints. Many people benefit from both.
Lion's Mane vs Alpha-GPC
Different mechanisms. Alpha-GPC for acute focus (hours). Lion's Mane for long-term brain health (8-16 weeks).
Berberine vs Inositol
Berberine for general blood sugar/cholesterol. Inositol for PCOS and fertility. Can be combined for best results.
L-Theanine vs Ashwagandha
L-theanine for acute calm (30-60 min). Ashwagandha for chronic stress resilience (4-8 weeks). Complementary, not competing.
GABA vs L-Theanine
L-theanine wins for most people. Oral GABA struggles to cross the blood-brain barrier. L-theanine has stronger evidence.
Magnesium L-Threonate vs Glycinate
Threonate for cognitive/brain effects (crosses BBB). Glycinate for sleep, anxiety, muscles at lower cost.
Bovine vs Marine Collagen
Bovine: Type I + III, joints/gut, lower cost. Marine: Type I, skin focus, faster absorption claims, premium price.
Eggshell Membrane vs Glucosamine + Chondroitin
Eggshell membrane: 500 mg, 7-10 day onset. G+C: 2,700 mg, 8-12 week onset, 50-70% cheaper.
