XL Nutrition Testosterone Booster, D-Aspartic Acid, Fenugreek, Zinc and D3 in a 3-Capsule Daily Serving
XL Nutrition Testosterone Booster is a 90-capsule daily blend. Each 3-capsule serving delivers eight active ingredients including five vitamins and minerals at doses that qualify for EU-authorised health claims under Regulation 432/2012:
- Zinc 16.2 mg (162% NRV) - zinc contributes to the maintenance of normal testosterone levels in the blood, and to normal protein synthesis, normal fertility and reproduction, and the normal function of the immune system.
- Vitamin D3 30 ug / 1200 IU (600% NRV) - vitamin D contributes to normal muscle function, the maintenance of normal bones, and normal calcium absorption.
- Magnesium 336 mg (90% NRV) - magnesium contributes to normal muscle function and to a reduction of tiredness and fatigue.
- Vitamin B6 8.2 mg (585% NRV) - vitamin B6 contributes to the regulation of hormonal activity, and to normal energy-yielding metabolism.
- Vitamin C 100 mg (125% NRV) - vitamin C contributes to the protection of cells from oxidative stress.
The formula also includes D-Aspartic Acid (1000 mg), Fenugreek 4:1 seed extract (533 mg), and Boron (10 mg). These three ingredients are present in the formulation; no EU-authorised health claims are associated with them at the time of writing.
Built for adults pursuing a structured training programme who want a daily multi-nutrient capsule with the zinc, vitamin D and magnesium doses pitched at the upper end of the NRV range. XL Nutrition own-brand value tier: honest sports-nutrition formulations at a price that makes daily use sustainable.

Solid results
I've been taking these every day for the last six months. While it's difficult to measure whether a vitamin (which is essentially what these are) is actually working, it's inevitable that your testosterone levels will dip as you age (I'm 50), and it's important to find a natural way to support testosterone development. I believe that this supplement does just that.
As a side note, I take XL Test alongside the XL Nutrition Build capsules. I've been taking both every day for six months.
I take all six capsules at once, in the morning.
The biggest result I've seen is that I feel less tired and, as a result of having more energy, my workouts are more intense.

Was on these before, took a break over Christmas, but back on them and certainly notice the difference being back on them.
