Supplements Worth Taking

The supplement industry sells a lot of noise. This is the short list of things with real evidence behind them for men focused on body composition, energy, and long-term health — plus what each one actually does.

Foundational

Creatine Monohydrate

The most-studied supplement in existence. Improves strength, power output, and muscle growth when paired with training, and has emerging evidence for cognitive benefits.

  • Increases strength and training capacity
  • Supports lean muscle retention, especially useful during a calorie deficit or on a GLP-1
  • Some evidence for brain energy metabolism and mood
Foundational

Protein Powder (Whey or Plant)

Not magic — just a convenient way to hit a daily protein target that's hard to reach through food alone, especially with a busy schedule or reduced appetite.

  • Supports muscle repair and growth
  • Helps preserve lean mass during fat loss
  • Improves satiety between meals
Foundational

Vitamin D3 (+K2)

A huge share of adult men are functionally deficient, especially with limited sun exposure. Low vitamin D is linked to lower testosterone, worse bone health, and immune function.

  • Supports hormone and immune health
  • Pairing with K2 helps direct calcium to bone rather than soft tissue
Foundational

Omega-3 (Fish Oil / Algae Oil)

Most men eat far more omega-6 than omega-3. Correcting that ratio supports heart, joint, and brain health.

  • Supports cardiovascular health
  • Anti-inflammatory effects that support joint recovery
  • Linked to improved mood and cognitive function
Recovery

Magnesium (Glycinate)

Involved in over 300 enzymatic processes, including sleep regulation and muscle relaxation. Commonly low in men who train hard or drink caffeine and alcohol regularly.

  • Improves sleep quality
  • Reduces muscle cramping
  • Supports stress and nervous system regulation
Recovery

Zinc

Critical for testosterone production, immune function, and wound healing. Deficiency is common in men with high sweat rates or restrictive diets.

  • Supports healthy testosterone levels
  • Supports immune function
Situational

Ashwagandha (KSM-66)

An adaptogen with reasonable clinical evidence for lowering cortisol and improving perceived stress, sleep, and in some studies, strength and testosterone.

  • May reduce perceived stress and cortisol
  • Some evidence for improved sleep and recovery
Situational

Fiber (Psyllium Husk)

Especially relevant for men on GLP-1 medications dealing with slowed digestion, or anyone not hitting 25-35g of fiber daily through food.

  • Supports regularity and gut health
  • Improves satiety and blood sugar response

What to Skip (Usually)

  • Proprietary "testosterone boosters" with no disclosed doses of active ingredients
  • Fat burners relying mainly on stimulants — the effect is caffeine, not fat loss
  • Most multivitamins as a substitute for actually eating vegetables
  • BCAAs if you're already eating enough total protein — redundant

Resources

Verify Third-Party Testing

Look for NSF Certified for Sport or Informed Sport seals, especially for creatine and protein — this confirms label accuracy and screens for banned substances.

Check the Evidence

Examine.com aggregates and rates the research behind individual supplements in plain language — a good first stop before buying anything.

Bloodwork First

Before supplementing vitamin D, zinc, iron, or magnesium long-term, get baseline bloodwork through your doctor so you're correcting an actual deficiency, not guessing.
