Pros and cons

Vitamin D3 2000 IU Softgels

  • USP Verified for ingredients, potency and manufacturing
  • 2,000 IU of D3 is half the adult upper limit
  • About $0.06 per day
  • Small softgel with an oil base that supports absorption
  • Gelatin shell, so not vegetarian
  • Soybean oil base may not suit people avoiding soy-derived ingredients
  • No vitamin K2 for those who want a combined formula

Advanced Testosterone Support

  • Shilajit at 500 mg per day matches the dose used in published trials of purified shilajit in men
  • Every ingredient amount is disclosed — no proprietary blend and no filler botanicals
  • Made by a brand with cGMP compliance, an NSF-certified facility, an A rating from Australia's TGA and four rounds of testing
  • Simple two-capsule daily dose; buyers consistently report no taste, no aftertaste and no side effects
  • Gluten-free, dairy-free and soy-free per Thorne's own verification
  • About $1.43 per serving at list price — steep for a four-ingredient formula
  • Ashwagandha at 120 mg is below the 300–600 mg used in most root-extract testosterone trials
  • Not NSF Certified for Sport, unlike several other Thorne products
  • Human evidence that luteolin meaningfully affects testosterone or aromatase is limited

Our verdicts

Vitamin D3 2000 IU Softgels

For most adults who want a daily vitamin D supplement, this is the benchmark: a sensible 2,000 IU dose, USP verification and a price that is hard to beat. Vegetarians should choose a gelatin-free option, and people who already have adequate levels should not expect broader health effects.

Full review

Advanced Testosterone Support

This is a clean, honestly dosed hormone-support formula from one of the most rigorously manufactured brands in the category, and shilajit at 500 mg is the one component genuinely matched to its research. But the overall evidence for raising testosterone with botanicals is modest, the ashwagandha dose is on the low side, and roughly $1.43 a day is a lot for four ingredients. Reasonable for men who want a conservative, fully disclosed option and have realistic expectations; not a substitute for sleep, training or medical evaluation of low testosterone.
