Creatine
Also known as: Creatine Monohydrate, Creatine Ethyl Ester, Buffered Creatine, Amino Acid Derivative
Creatine is a naturally occurring compound synthesized from amino acids that plays a critical role in energy production during high-intensity exercise. It is stored in muscles as phosphocreatine, which rapidly regenerates ATP (energy currency). Creatine is one of the most studied and effective sports supplements.
Benefits
Enhances athletic performance and muscle strength during high-intensity exercise. Increases muscle mass and supports muscle growth. Improves power output and training capacity. Supports brain health and cognitive function. May improve muscle endurance and recovery. Increases cellular energy availability. Supports mental health and mood.
Recommended Dosage
No established RDA. Common supplementation: Loading phase 20 grams daily (5 grams 4x daily) for 5–7 days, then 3–5 grams daily maintenance. Alternatively, take 3–5 grams daily without loading. Effects take 2–4 weeks to manifest. Creatine monohydrate is most studied and cost-effective. Take with carbohydrates and protein for absorption.
Food Sources
Red meat (beef), fish (salmon, tuna), poultry (chicken), eggs, milk, seaweed (small amounts).
Side Effects
Generally safe and well-tolerated. Mild side effects: water retention (1–2 pounds), bloating, stomach cramps, diarrhea, nausea. Some report muscle cramping. High doses may cause kidney stress (in those with predisposition). Hair loss reported anecdotally but not proven.
Interactions
May enhance effects of diuretics (dehydration risk). Interactions with standard medications unlikely at recommended doses. Caffeine may reduce creatine effectiveness. NSAIDs may reduce absorption. Works synergistically with beta-alanine and other performance supplements.
Warnings
Those with kidney disease should avoid or use only under medical supervision. Adequate hydration is essential during supplementation. Pregnant and breastfeeding women should avoid. Those taking cephalosporin antibiotics should monitor kidney function. Not recommended for children without medical guidance.
Deficiency Symptoms
Poor exercise performance and reduced muscle strength. Lower muscle mass and difficulty building muscle. Reduced energy availability during intense effort. Potential cognitive decline (in those with naturally low creatine).

Vitamin D
Vitamins
Vitamin D is a fat-soluble vitamin that plays a crucial role in calcium absorption, bone health, immune function, and mood regulation. Unlike most vitamins, your body can produce vitamin D when your skin is exposed to sunlight, earning it the nickname 'the sunshine vitamin.'
Vitamin C
Vitamins
Vitamin C is a water-soluble vitamin and powerful antioxidant that the human body cannot produce on its own. It is essential for the growth, development, and repair of all body tissues and plays a role in many body functions including immune defense, collagen formation, and iron absorption.
Omega-3 Fish Oil
Fatty Acids
Omega-3 fatty acids are essential polyunsaturated fats that your body cannot make on its own. The two most important omega-3s found in fish oil are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). They play critical roles in brain function, heart health, and reducing inflammation throughout the body.
