Supplements
Every supplement we cover, in one place. Read the review first: each one explains what the studies found, the limits of that evidence and who should avoid it. Supplements are not a substitute for sleep, training and diet, and you should check with a doctor before taking anything.
Nature's Truth Ashwagandha (90 capsules)
6.5 / 10
A sensible, simple ashwagandha capsule at a trial-like extract amount. The research on stress and cortisol is encouraging but small, and this exact product has not been tested.

NOW Vitamin D3 1000 IU (360 softgels)
7.5 / 10
A simple, well-known, low-dose vitamin D3 softgel with good value per bottle. Most useful for men who are low in vitamin D; the testosterone evidence in men with normal levels is weak.

Thorne Zinc Picolinate 30 mg (60 capsules)
7 / 10
A clean, third-party tested zinc capsule from a respected brand. Worth considering if your diet or heavy training leaves you short on zinc. Unlikely to change testosterone if your zinc is already normal, and 30 mg is a high daily amount, so it isn't one to take long term without good reason.

NOW Magnesium Glycinate (180 tablets)
7.5 / 10
A good-value, gentle magnesium from an established brand, listed as halal and vegan. Most useful for men who are low in magnesium or train hard. The testosterone evidence is limited and comes from small studies.

BulkSupplements Longjack (Tongkat Ali) Extract (120 capsules)
5.5 / 10
A cheap, simple tongkat ali capsule, but the listing doesn't give the extract strength or standardisation, which the studies relied on. Tongkat ali has some promising small trials, mostly in older or stressed men. It's a gamble compared with zinc, vitamin D or magnesium.
