How Does Nature’s Bounty Sublingual B-Complex Work?
Nature’s Bounty Sublingual B-Complex works by delivering essential B vitamins directly to the body in a liquid form that is absorbed quickly under the tongue. These B vitamins play a role in helping the body produce energy and maintain a healthy nervous system.
According to research in Nutrients, Thiamin, riboflavin, niacin, and vitamin B6 are essential micronutrients that are mainly involved in energy metabolism; they may prevent the occurrence of developmental abnormalities and chronic degenerative and neoplastic diseases.
By using a sublingual delivery system, Nature’s Bounty claims the product is absorbed faster than pills and this allows for quicker effects. This may help people feel more energetic and maintain better focus throughout the day. However, individual results can vary based on health and lifestyle factors.
Nature’s Bounty Sublingual B-Complex Ingredients: Are They Safe & Effective?
Here are some of Nature’s Bounty Sublingual B-Complex main ingredients:
Vitamin B-6 (Pyridoxine Hydrochloride)
Vitamin B-6 plays an important role in converting food into energy and supports brain function. However, a review in the Cochrane Database of Systematic Reviews found no evidence of short-term benefits from vitamin B6 in improving mood (depression, fatigue, and tension symptoms) or cognitive functions.
Vitamin B-12 (Cyanocobalamin)
Vitamin B-12 is known for its role in energy production and red blood cell formation. As highlighted in our Performance Lab Nutrigenesis Multi Men Review (another supplement containing this ingredient), this B vitamin supports healthy brain, heart, and nervous system function and is essential in producing red blood cells.
A meta-analysis published in Nutrients suggests that Vitamin B12 is often used to improve cognitive function, depressive symptoms, and fatigue.
Niacin (Vitamin B-3)
Niacin supports healthy skin, digestion, and nerve function. It also helps the body convert food into energy. As documented in our VitalRize Review (another supplement containing this ingredient), Niacin also reduces inflammation and supports cardiovascular health.
Additionally, an article in Mount Sinai says that Niacin helps improve circulation, and it has been shown to suppress inflammation.
Pantothenic Acid (Vitamin B-5)
Pantothenic acid aids in the production of energy and helps the body use fats, proteins, and carbohydrates. It also supports the nervous system.
According to a study published in the Dermatology and Therapy Journal, the administration of a pantothenic acid-based dietary supplement in healthy adults with facial acne lesions is safe, well tolerated, and reduces total facial lesion count.
Riboflavin (Vitamin B-2)
Riboflavin helps the body break down proteins, fats, and carbohydrates for energy. A study in the International Journal for Vitamin and Nutrition Research suggests that supplementation with vitamin B2 in adults can play a positive role in reducing the frequency and duration of migraine attacks with no serious side effects.

Oliviamariebish gave it 5 stars, saying, So I started using the sublingual B vitamin, and It is amazing!!! I talked to some of my doctors, and they all said Unless you got the shots, this was really the only other way a significant amount would be absorbed. So I am about 3 months in, and I take it daily, I highly recommend trying this out.”
On the other hand, tracyp63 rated it 1 star, stating, This tastes really nasty. I got it originally for my husband, and he took it one time and said never again. It was just stilling on the shelf, and I tried it to help with energy levels, and I agreed it tasted nasty after one time, so it’s still sitting on the shelf unexpired.”
Another user, Energygirl, added, I’m going to throw the bottle away it’s so very nasty” >
