1 of 8 recognized ingredients hit their clinically studied dose.

Ingredients vs the studied dose

IngredientLabel doseStatus
Zinc
40mg zinc citrate — above the 30mg dose (the one genuinely-dosed active)
40mg✓ OK
D-Aspartic Acid
2g D-aspartic acid — below the ~3g studied amount (and the evidence is shaky)
2g⚠ LOW
Fenugreek Extract
200mg fenugreek 4:1 extract — the '800mg' is raw-herb equivalent
200mg (labeled '800mg equiv')⚠ LOW
Vitamin D3
26.68mcg vitamin D3 (~1,068 IU) — about half the 2,000 IU target
1068 IU⚠ LOW
Green Tea Extract (EGCG)
~70mg EGCG — the '4,000mg' is raw-leaf equivalent, far below the 400mg dose
200mg 20:1 (70% catechins)⚠ LOW
Panax Ginseng
40mg ginseng 200:1 extract — the '8,000mg' is raw-root equivalent
40mg (labeled '8000mg equiv')⚠ LOW
Ashwagandha (KSM-66)
55.67mg KSM-66 12:1 extract — a tenth of the 600mg studied dose
55.67mg (labeled '668mg equiv')⚠ LOW
Garlic Extract
16mg garlic 100:1 extract — a token amount, effectively fairy dust
16mg (labeled '1600mg equiv')⚠ LOW

The verdict

This is a masterclass in "equivalent" inflation. The label shouts 668mg ashwagandha, 8,000mg ginseng, 1,600mg garlic, 4,000mg green tea — but read the small print and those are raw-herb equivalents. The actual extract you get is 55mg ashwagandha, 40mg ginseng, 16mg garlic. Graded on the real amounts, only the zinc hits its dose; almost everything else is fairy dust wearing a big number. Fully disclosed, to its credit — but the disclosure is what exposes it.
