AI Comparison Analysis
Thorne Basic B Complex - 60 Capsules vs Holland & Barrett Vitamin D3 4000 IU (100mcg) Tablets - 120 Count
Thorne Basic B Complex - 60 Capsules: Thorne Basic B Complex is the gold standard for bioactive B-vitamin supplementation, using tissue-ready forms throughout including methylfolate and methylcobalamin. The NSF Certified for Sport designation provides exceptional third-party quality assurance that few competitors match. Users with MTHFR variants and methylation concerns consistently report noticeable benefits. The main barrier is price — it costs significantly more than standard B complexes, and those without specific genetic or health needs may not benefit from the premium formulation.

Holland & Barrett Vitamin D3 4000 IU (100mcg) Tablets - 120 Count: Holland & Barrett's Vitamin D3 4000IU is a functional, affordable option that delivers an effective dose at the lowest price in its category. User blood test results confirm it works for raising vitamin D levels. However, the tablet format with bulking agents is less elegant than oil-based softgels, and absorption may be somewhat reduced without a lipid carrier. It is best suited for budget-conscious consumers who prioritise price over formulation quality.
