What is the source of the vegetable capsules?

The plant fiber used to make the vegetable capsules is all-natural alpha cellulose derived from the pulp of specially selected, high-grade Southern soft pine trees.

I took Forbose and felt light-headed or another symptom of hypoglycemia, why?

Unlike most sugars, ribose (one of the key ingredients in Forbose™) can actually lower blood glucose. If prone to hypoglycemia, take Forbose with meals to counter that effect.

Why vegetable capsules?

Although the Bulletproof diet contains some animal-sourced protein, it also contains loads of healthy and delicious vegetables. Bulletproof strives to offer the best quality products possible, and vegetable capsules do just that. Although they are more expensive than the standard animal-sourced gelatin capsule, they offer some great benefits compared to gelatin. They’re 100% natural, vegetarian/vegan friendly, and more stable than gelatin when exposed to heat and humidity.

The dark brown, light brown and off-white particle sizes in my capsule are not uniform, is this normal?

Yes, these are all-natural ingredients and visual appearance may vary. The larger particles are from the Coleus forskohlii root.

What are excipients and flow agents? Why is there rice on the label?

Excipients and flow agents such as rice ingredients are part of the manufacturing process required to encapsulate ingredients. Bulletproof formulates its products with the latest technologies and adopts new and improved technologies as they become available. We have chosen to use the outermost layer of the rice grain (rice hull or bran) because it is one of the cleanest excipients available. Other options are less natural, like polydimethylsiloxane, sodium bicarbonate, stearic acid, and powdered cellulose. We use the least possible amount of rice hull or bran as necessary in the manufacturing process, ensuring minimal rice content that carries no discernible impact on the amount of complex carbohydrates in your individual diet.
