What Dr. Brad Stanfield Thinks About Longevity Supplements: A Critical Overview

Dr. Brad Stanfield is known for taking a conservative, science-first approach to longevity. A general practitioner based in New Zealand, he runs a popular YouTube channel where he reviews clinical trials, supplements, and health trends — always asking whether the evidence is strong enough to justify the hype.

This article is an independent, journalistic summary of supplements Dr. Stanfield has publicly discussed. For Youth is not affiliated with Dr. Stanfield , and this article should not be seen as an endorsement of our products. It is intended purely to help readers understand how his views compare with currently available formulations.

Dr. Stanfield has often highlighted magnesium — especially in forms that cross the blood–brain barrier — as useful for improving sleep, brain health, and overall wellbeing. While he doesn’t push specific brands, he supports the general use of magnesium L-threonate for its superior neurological effects.

The Unwind features magnesium L-threonate in a clean, research-backed formula designed for sleep, stress, and cognitive support:

Dr. Stanfield supports collagen supplementation, particularly for joint and skin health as we age. He cites studies suggesting that hydrolysed collagen may improve skin elasticity and reduce signs of ageing — especially when taken consistently over time.

The Skin is For Youth’s daily collagen supplement — formulated for elasticity, hydration, and long-term joint support:

Dr. Stanfield has spoken about NMN — but cautiously. While he recognises the theoretical promise of NMN as an NAD⁺ booster, he has expressed concerns over the lack of large, long-term human trials and does not actively recommend its use. That said, his commentary is often nuanced, acknowledging that NMN has a strong mechanistic rationale and encouraging more rigorous research.

If you’re exploring NMN on your own terms, The Repair and The Base offer well-formulated options with clean, tested ingredients:
