Alpha-Lipoic Acid
Also known as: ALA, Thioctic Acid, Lipoic Acid, Alpha-Lipoate
Alpha-lipoic acid is a powerful antioxidant compound synthesized by your body and found in small amounts in foods. ALA is unique because it is both water and fat-soluble, allowing it to work throughout the entire cell. It plays essential roles in energy production and has been shown to regenerate other antioxidants like vitamins C and E, amplifying their protective effects.
Benefits
Powerful antioxidant with cellular protection against free radical damage; supports blood sugar regulation and may improve insulin sensitivity; reduces peripheral neuropathy pain in diabetic patients; supports weight management and energy production; may reduce inflammation; enhances brain health and cognitive function; supports eye health.
Recommended Dosage
Supplementation typically ranges from 100-600 mg daily, with most clinical studies using 300-600 mg doses divided into two or three parts. ALA is best absorbed on an empty stomach, 30 minutes before meals. Taking with food can reduce absorption by up to 30%, though taking with meals may minimize nausea.
Food Sources
ALA is found in small amounts in red meat (especially beef), organ meats (liver, kidney), spinach, broccoli, Brussels sprouts, and tomatoes. However, dietary amounts are minimal compared to supplement doses; food sources provide only 5-10 mg per serving.
Side Effects
Generally well-tolerated. Mild side effects include nausea, stomach upset, or diarrhea, especially when taken on an empty stomach. Some individuals report a 'sulfur-like' body odor or taste. Insomnia or vivid dreams have been rarely reported. Rash or itching occurs in a small percentage of users.
Interactions
May lower blood sugar levels, potentially enhancing diabetes medication effects; monitor glucose closely if combining. May reduce effectiveness of thyroid medications; separate doses by 4+ hours. Can enhance anticoagulant effects of blood thinners. May interact with chemotherapy agents; consult oncologists before use.
Warnings
Not recommended during pregnancy or breastfeeding without medical guidance. Individuals with thiamine (vitamin B1) deficiency should not take ALA, as it may deplete B1. Those with diabetes should monitor blood glucose closely as ALA may lower it. Use cautiously in those with iron overload disorders.
Deficiency Symptoms
ALA deficiency is not a recognized clinical condition since the body synthesizes adequate amounts for normal function. However, in disease states or with aging, reduced ALA production contributes to oxidative stress and impaired glucose metabolism.

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.

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.
