Natural vitamin E is a fat-soluble vitamin and is usually best taken after a meal. It should not be taken orally immediately after meals. The best time period is 30 minutes after meals to achieve the best absorption and digestion effect and not to stimulate and burn the gastric mucosa, causing excessive secretion of gastric acid, and long-term use will not cause the gastric mucosa and digestive system burden, causing symptoms such as gastric mucosa burn. If the need for vitamin E supplementation is not large, it can also be taken at bedtime. Taking natural vitamin E at bedtime also has the effect of improving sleep and preventing insomnia and excessive dreaming. Therefore, for 3 times/day orally, it is recommended to take one capsule 30 minutes after three meals; if 1 time/day, it is recommended to take one capsule 30-40 minutes before bedtime.
