National Nutrition Month is not about perfection.
It’s about awareness

We consistently see the same nutritional gaps — even among well-meaning, health-conscious adults.

Many people are eating “better,” but they are still undernourished at the cellular level. Let’s simplify what truly matters.

A Welcome and Reintroduction:

Dr. Coeurlida Louis Ashby is a Board-Certified Lifestyle Medicine Intensivist, Yale-trained physician, and former Chief Resident of Yale Primary Care with over 29 years in healthcare. Beginning her career as a Registered Nurse in 1996 and practicing Internal Medicine for more than two decades.

As Professional Bodybuilder she has advanced nutrition knowledge and a deep foundation in cardiometabolic and preventive medicine. As a Lifestye Medicine Intensivist she specializes in restoring health by addressing root causes rather than simply managing disease.

She believes nutrition is the most powerful tool we have to improve our health— when used intentionally, it nourishes the body at the cellular level and lays the foundation for strength, healing, and long-term vitality.

Let's Get Our Nutrition RIght:

Omega-3 deficiency is extremely common. These essential fats regulate inflammation, support brain function, protect the heart, and improve metabolic health.

Why levels stay low:

  • Low fatty fish intake
  • High intake of processed omega-6 oils
  • No lab testing to confirm adequacy

What to consider:

  • High-quality fish oil or algae-based omega-3
  • Periodic Omega-3 index testing

“Filling the Gaps” List: If I had to recommend a simple nutritional support foundation to discuss with your physician, it would include:
  • A high-quality multivitamin
  • Vitamin D3 with K2
  • Omega-3 fatty acids
  • B12 and/or B-complex
  • Magnesium
  • Fiber support
  • Adequate protein intake
  • Creatine (if appropriate)

.

Despite increased awareness, vitamin D deficiency remains widespread.

Most people:

  • Do not know their actual blood level
  • Supplement inconsistently
  • Fail to recheck levels

Vitamin D supports immune health, bone strength, mood stability, metabolic balance, and cardiovascular protection.

Best practice:​
Measure. Replace. Re-measure.
Vitamin D3 paired with K2 supports proper calcium balance.

Magnesium for Stress and Sleep

Commonly depleted by:

  • Stress
  • Processed foods
  • Poor soil quality

Magnesium supports sleep, blood pressure, muscle function, and stress regulation

Protein , Creatine & Muscle

Low Muscle Mass is one of the most overlooked health risks.

It is driven by:

  • Inadequate protein intake
  • Minimal resistance training
  • Aging-related muscle loss

Muscle is not cosmetic — it is metabolic protection.

Creatine supports muscle strength, cognitive health, and metabolic resilience.

Talk to your doctor to make sure taking protein and creatine are right for you.

Nutrition details and recommendations are in Dr. Ashby's Nutrition Protocol on Fullscript:

Low B12 is common even in individuals who believe they eat adequately. Symptoms may include:

  • Fatigue
  • Brain fog
  • Numbness or tingling
  • Mood changes

Your body deserves strength.
Your future deserves intention
