Jun 04, 2026 · 13 min read

Yes. Trauma can disrupt desire, erections, orgasm, and intimacy, and those symptoms can overlap with hypogonadism when persistent symptoms are present and morning testing shows total testosterone below 350 ng/dL or free testosterone below 100 pg/mL, with confirmation as needed. That is why trauma and relationships, men’s mental health, sexual health, and relationship stress often ...

Veedma's editorial team: Evidence-based men's health

May 28, 2026 · 15 min read

The best supported biohacking supplements for men are a short list, not a 20 bottle stack: creatine at 3 to 5 g daily, protein support when intake is low, vitamin D when labs show deficiency, and targeted minerals or electrolytes when diet or sweat losses create a real gap.

The best supplements for low energy in men are the ones that match the cause, not the loudest label, and testosterone treatment belongs only to men with symptoms plus properly confirmed low levels, typically below 350 ng/dL total testosterone or 100 pg/mL free testosterone on morning testing.

You should track your health metrics over time with daily wearable and home readings plus at least two lab updates a year, especially if testosterone is below 350 ng/dL or free testosterone is below 100 pg/mL with symptoms.

What affects male intimacy, libido, and sexual health? Relationship advice for men

Veedma's editorial team: Evidence-based men's health

Apr 23, 2026 · 14 min read

Male intimacy, libido, and sexual health are shaped by hormones, blood flow, mood, pain, and relationship quality, and true testosterone deficiency is only diagnosed when symptoms persist alongside low testosterone on properly timed morning testing, with LH and FSH measured to classify primary versus secondary hypogonadism. That is why good relationship advice for men starts ...

Keto diet and CGM: What your glucose level can look like and how to avoid reverse metabolic inflexibility

Veedma's editorial team: Evidence-based men's health

Feb 07, 2026 · 12 min read

On a ketogenic diet, CGM traces often show a lower, flatter 24-hour glucose curve, while an occasional high-carb meal can cause a higher peak and slower return to baseline that can reflect low-carb adaptation rather than automatically proving insulin resistance. Reproducible large excursions or abnormal fasting glucose or HbA1c still warrant medical evaluation. Learn how ...

Blueprint protocol review: Do Bryan Johnson’s supplements really help heart, vascular, and sexual health?

Veedma's editorial team: Evidence-based men's health

Jan 30, 2026 · 12 min read

No. There is no published clinical trial showing that the full Blueprint stack improves men’s heart, vascular, or sexual health. The Blueprint Stack is a $361 per month breakfast and supplement bundle that delivers about 400 calories, 26 g of plant protein, and roughly eight daily pills. That makes most Blueprint review claims an evidence ...

Inflammation and heart disease in men: What to test and what to do next

Veedma's editorial team: Evidence-based men's health

Jan 28, 2026 · 11 min read

Chronic, low-grade inflammation is a proven risk factor for atherosclerotic heart disease, and simple blood tests can detect it before symptoms appear. If your cholesterol looks “fine” but your family history, waistline, or energy say otherwise, inflammation may be the missing piece in your heart risk assessment. “Think of cholesterol as the building material for ...

Building muscle after 40: The smarter plan for strength, recovery, and hormones

Veedma's editorial team: Evidence-based men's health

Jan 26, 2026 · 11 min read

Yes, building muscle after 40 is absolutely possible for men, but you usually need a tighter plan for training, protein, recovery, and hormone health than you did at 25. The win is not “more grind.” It is better programming, better fuel, and better monitoring so you can keep progressing with fewer setbacks. “After 40, the ...

Bulking vs cutting for men: How to pick the right bulk vs cut plan and keep it healthy

Veedma's editorial team: Evidence-based men's health

Jan 26, 2026 · 12 min read

Choose a bulk if you are relatively lean and your main goal is size and strength. Choose a cut if your waist or body fat is trending high or you need to make weight. In either phase, keep the calorie change modest and continue lifting. “Most guys do not fail because they pick the wrong ...

Testosterone and the Dietary Guidelines for Americans: What men should actually do

Veedma's editorial team: Evidence-based men's health

Jan 21, 2026 · 12 min read

The Dietary Guidelines for Americans (DGA) do not provide testosterone targets. Men can use the DGA to support a healthy body weight and cardiometabolic health, which can indirectly support testosterone, and should seek medical evaluation for persistent symptoms or repeatedly low morning labs. Here’s what diet can improve, what it can’t, and how to act ...
