Nitric Oxide Supplement: Why Need After Age 40?

As we reach to our 40s, our body starts showing noticeable changes to affect our energy, memory, blood pressure, and even intimacy. While many chalk this up to "normal aging," there's a hidden secret that works: declining nitric oxide levels. To boost you back into an energetic health form, a scientifically formulated Nitric Oxide Supplement can be a game-changer at your aging health.

In fact, research shows that by age 70, nitric oxide levels can fall by 75%, and by 80, as much as 85%. This decline contributes to fatigue, poor circulation, mental fog, joint discomfort, and more. But with the right Nitric Oxide Supplement, you can restore these levels quickly and safely.

 

What Is Nitric Oxide and Why It Matters

In a healthy individual, Nitricoxide is naturally produced by our body to keep blood vessels open, oxygen flowing, and your brain firing. Often called the “youth molecule,” it supports cardiovascular health, energy, cognitive clarity, and even intimacy.

The problem? Your body’s nitric oxide production declines dramatically after 40 — and even more so by 70.

When nitric oxide plummets, your body struggles to:

  • Circulate oxygen and nutrients efficiently
  • Maintain blood pressure and heart health
  • Power your muscles and stamina
  • Support memory and mental focus
  • Deliver peak performance — physically and mentally

This is where a Nitric Oxide Supplement like CircO2 offers rapid and transformative support.

Discover CircO₂: Your Fast-Acting Nitric Oxide Booster

CircO₂ is more than just a lozenge—it’s a science-backed breakthrough. Developed with expertise from MIT researchers, this fast-dissolving nitric oxide (NO) supplement works right where NO production begins: in your mouth. Clinically shown to double nitric oxide levels in just 20 minutes and boost blood flow by 34%, CircO₂ promotes wellness, energy, and vitality faster than traditional capsules.

Why Most Nitric Oxide Supplements Fail?

Many traditional nitric oxide supplements rely on outdated methods:

  • L-Arginine: Although once popular, lose up to 75% of their effectiveness in digestion. After age 45, your body also struggles to convert L-arginine into nitric oxide.
  • Beet Juice or Greens: While natural, you'd need to consume 2–3 pounds of beets or spinach daily to see results — and nutrient quality can vary by soil.
  • Pills and Capsules: MIT scientists discovered nitric oxide production starts in your mouth, not your gut. Pills that bypass this miss the crucial first step.

Why Choose CircO₂ Over Other NO Supplements?

  • Backed by MIT science and designed for rapid, efficient NO production.
  • Micro-delivery system avoids digestion delays and improves bioavailability.
  • Clean, quality-assured formula—vegan, gluten-free, non-GMO. 
  • Manufactured in GMP-certified facilities. 

If you're aiming to support circulation, increase energy, sharpen your focus, or enhance workout recovery—especially as you get older—CircO₂ offers a practical, fast-acting boost. Its convenient lozenge format makes it ideal for daily use or before workouts.


Why CircO₂ Works So Fast

  • Oral delivery harnesses the nitrate–nitrite–NO pathway
    LOZENGE dissolves in the mouth, allowing nitrites to form directly under the tongue. This shortcut bypasses digestion and elevates NO levels quickly—200% in just 20 minutes, according to MIT-backed studies.

  • Clinically proven blood flow benefits
    In as little as 20 minutes, CircO₂ raises NO by 200% and enhances circulation by 34%, helping your body maximize oxygen and nutrient delivery.
How to Use CircO₂

  • Take one lozenge daily, letting it dissolve slowly (1–2 minutes). 
  • Best absorbed on an empty stomach or between meals. 
  • Users often feel effects—like warmth in extremities or a surge in energy—in under 20 minutes.

Ingredients You'll Love in CircO2 Nitric Oxide Supplement

  • CircO₂ blends a premium mix of natural, synergistic ingredients known to support cardiovascular and endothelial health:

  • L‑Citrulline – Converts to L‑arginine, fueling the body’s NO production pathway.
  • Beetroot Powder – A rich source of nitrates, boosting endurance, circulation, and blood pressure support.
  • Hawthorn Berry Extract – Traditional heart tonic that improves microcirculation and supports arterial health.
  • Magnesium, Vitamin C & B12 – Essential co-factors: magnesium supports vessel relaxation; vitamin C protects NO and assists collagen; B12 supports energy and cognitive sharpness.
  • Sodium Nitrite – Helps stabilize nitrites for efficient NO release.

Together, these ingredients form a complete nitric oxide restoration system that’s powerful, natural, and fast-acting.

Benefits of Taking a Nitric Oxide Supplement After 40

1. Cardiovascular & Circulation Support: Supports healthy blood pressure and vessel flexibility. More oxygen-rich blood to your brain, heart and muscles. 

2. Energizes & Fights Fatigue: Improved blood flow and nutrient delivery means more stamina, focus and less brain fog.

3. Exercise & Performance Booster: Beet and citrulline nitrates support endurance and recovery—used by athletes for a performance edge.

The Perfect Pair: CircO2 and Advanced Mitochondrial Formula

The CircO2 Nitric Oxide Supplement pairs exceptionally well with the Advanced Mitochondrial Formula, as both are scientifically formulated to boost energy, enhance vitality, and support healthy aging—each from a unique but complementary angle.

CircO2 works by increasing nitric oxide levels, which naturally dilate blood vessels and improve circulation. This leads to better oxygen and nutrient delivery throughout the body, including to the mitochondria—the cellular powerhouses responsible for producing energy. When mitochondria receive more oxygen, their ability to perform aerobic respiration and ATP production improves significantly.

At the same time, the Advanced Mitochondrial Formula directly supports mitochondrial structure and function by delivering essential nutrients. These ingredients help repair and regenerate mitochondria, reduce oxidative stress, and maximize energy output at the cellular level.

Together, these two supplements create a synergistic energy-boosting system: one enhances the environment (blood flow and oxygenation), while the other strengthens the engine (mitochondria themselves). For anyone looking to fight fatigue, support brain and cardiovascular health, and reclaim youthful vitality, combining CircO2 and the Advanced Mitochondrial Formula offers a powerful, science-backed solution.

An Amino Acid Supplement That Delivers Beyond BCAAs

Image
Why Amino Acid Supplements Matter Amino acids in human health and fitness Amino acid supplements are gaining traction not just among athletes but also health-conscious individuals looking to improve overall well-being. Why? Because amino acids are the building blocks of life — compounds that your body uses to make proteins, enzymes, hormones, neurotransmitters, and more. There are 20 amino acids, and nine of them are considered Essential Amino Acids (EAAs) — meaning your body can’t make them on its own. These include leucine, isoleucine, valine (the 3  BCAAs ), as well as others like lysine, methionine, and tryptophan. They must come from food or amino acid supplements for healthy life. In various health situations — whether you’re recovering from illness, aging, managing stress, or following a plant-based diet — the need for balanced amino acid intake becomes more urgent. That’s where Advanced Amino Acid supplements can help. They offer a complete, bioavailable spe...
