About the Brand
Solgar is a brand in the dietary supplement industry with over 75 years of experience. The company says they’ve always worked with nutrition scientists and do not add unnecessary fillers to their products.
Solgar manufactures its products in facilities in the USA and claims to follow standard production practices. They also say they are committed to the goal of seeing a hunger-free America.
However, the fact that they are silent about whether or not their facility is FDA-approved and GMP-certified makes a lot of potential buyers skeptical about trying its product.
Also, the lack of a money-back guarantee and the high price of its products may raise concerns for potential buyers.
How Does Solgar B-Complex “100” Work?
Solgar B-Complex “100” aims to support the body’s energy production and general health by providing a blend of essential B vitamins. It uses all these vitamins to convert carbohydrates, proteins, and fats into energy that the body can use.
For instance, Vitamin B1 helps convert carbohydrates into energy; Vitamin B6 supports amino acid metabolism; and Vitamin B3 helps to produce energy.
B12 in the form of cyanocobalamin is also included, which according to studies, is a synthetic compound of vitamin B12 used to treat vitamin deficiencies. Vitamin B12 may aid red blood cell formation and nervous system function. However, research suggests that this form of B12 (cyanocobalamin) in the capsule form may not be as beneficial as methylcobalamin.
Also, while Solgar states claims that make the product very promising, there are limited clinical studies to support this specific formulation.
Solgar B-Complex “100” Ingredients: Are They Safe & Effective?
Vitamin B1 (Thiamin)
Vitamin B1 is essential for converting carbohydrates into energy. It supports the nervous system and helps maintain proper muscle function.
As stated in our article on What Does Thiamine Do to Your Body? It’s Benefits & Side Effects, we mention that Thiamine improves digestion and energy production and also helps with brain health. Also, as reported in a StatPearls article, Thiamin plays a crucial role in energy metabolism and cardiovascular health.
Ma?gorzata Mrowicka, an Assistant Professor and Lecturer in Biochemistry, said,
Thiamine plays a special role in the body as a coenzyme necessary for the metabolism of carbohydrates, fats and proteins. It also participates in energy production in the mitochondria and protein synthesis.
Vitamin B2 (Riboflavin)
Riboflavin aids in breaking down fats, carbohydrates, and proteins. As documented in our WOWMD B-12 Complex Liquid Review (another supplement containing this ingredient), riboflavin is also used for the production of energy and the maintenance of healthy skin and eyes.
A study in the International Journal of Molecular Sciences shows that Riboflavin aids in breaking down food into fuel to ensure optimal cellular function.
Vitamin B3 (Niacin)
Niacin is vital for converting food into energy at the cellular level. It supports skin health, improves cholesterol levels, and promotes cardiovascular health.
According to the American Journal of Physiology, niacin helps to improve metabolic functions and reduce inflammation. However, high doses may cause side effects like flushing or discomfort.
In addition, Dr Laura White, a Clinical Nutritionist, states,
Niacin supplementation significantly improves metabolic functions and reduces inflammation, aiding overall health.
Vitamin B6 (Pyridoxine)
Vitamin B6 plays a significant role in amino acid metabolism, neurotransmitter production, and red blood cell formation. A study in the Journal of Human Psychopharmacology shows that it can help reduce stress and improve metabolic processes.
Vitamin B12 (Cyanocobalamin)
Vitamin B12 is critical for nerve function, DNA synthesis, and red blood cell production. Its inclusion ensures the body has enough oxygen to support energy production.
According to a study published in Nutrients Journal, Cyanocobalamin helps with energy production and neurological health, which makes it important for maintaining vitality. However, cyanocobalamin (while commonly used) may not be as readily absorbed as methylcobalamin.
Folic Acid
Folic acid, or Vitamin B9, is essential for DNA synthesis and cell division. It also supports cardiovascular health by lowering homocysteine levels (which may reduce the risk of heart disease). Research in the Journal of American Heart Association links folic acid to improved heart and brain function.
How to Use Solgar B-Complex “100”?
To get the most out of Solgar B-Complex “100”:
