The average adult loses 30% of their muscle by age 70

Stronghold is designed for active adults 50 and older who want to maintain muscle strength, energy, and independence as they age. Whether you're hiking, playing pickleball, chasing grandkids, or simply want to keep doing everyday things without slowing down, Stronghold delivers the clinical nutrition your body needs in one daily drink. It's also a fit if you're on GLP-1 medications and want to protect against muscle loss during weight loss. Not suitable for anyone under 18 or those who are pregnant or breastfeeding.

Mix one scoop into 8-10oz of cold water and stir or shake. That's it. Stronghold uses clear whey protein isolate, so it mixes like juice, no blender required, no chalky texture, no milky thickness. Take it every morning as part of your daily routine.

Many customers report improved energy and reduced fatigue within the first 2-3 weeks. Creatine saturates your muscles over approximately 3-4 weeks of daily use. Clinical trials on urolithin A showed measurable improvements in muscle endurance at 2 months, with continued gains through 4 months. Consistency is what matters most, the benefits build over time.

Stronghold contains natural food-derived ingredients and is generally well-tolerated alongside most medications. However, you should always consult your provider before starting. We always recommend bringing the ingredient label to your next appointment.

The whey protein is derived from dairy, so it is vegetarian but not vegan. Every other ingredient: creatine, HMB, urolithin A, vitamins D3, K2, and magnesium, contains no animal products.

Light, slightly fruity, and not too sweet. We use clear whey protein isolate (not the thick, creamy kind), natural flavor, a touch of stevia, and freeze-dried raspberry.

If you're not satisfied within 90 days of your first order, we'll refund you in full, no questions asked, guaranteed. We'd rather you try it with zero risk than wonder if it works.
